    [001] The present invention relates to a flow regulating valve for liquid-conducting heating or cooling systems, which consists of a housing with at least one inlet and at least one outlet and connection nozzles disposed between them, and in which a pressure regulating device is inserted, which maintains constant the pressure difference between the pressure regions before and after a flow regulating unit disposed in the connection nozzles, as well as a rod, with a drive part, which it protrudes from the housing and a first throttle body, which is located in the housing, and which acts on the flow regulating unit or parts thereof.
    [002] In particular, the invention relates to a flow regulating valve, which works dynamically, by means of which the flow is regulated in such a way that it remains constant over the entire valve, regardless of the pressure difference.
    [003] From document PCT/DE 2008/000669 a combination of components for regulating the flow rate and/or differential pressure in liquid-conducting heating or cooling systems is known, in which in the flow direction of the circulating medium, subsequently the inlet nozzle is followed by a first regulating device, then a first flow regulating device, then a second flow regulating device, and finally the discharge nozzle.
    [004] The known combination of components is complex in production because the corresponding components, which have to be produced in advance, need to be assembled in the housing. This not only means a large production effort, but it also has the consequence that the carcass needs to be formed relatively large. It is also disadvantageous that hitherto known configurations cannot be combined in a simple way with commercial flow thermostat valves, which are currently in use by the millions.
    [005] To carry out a hydraulic regulation in a fluid-conducting heating or cooling system, it is advantageous to install a valve with an integrated pressure regulating device on the individual consumers. As the plurality of valves in existing systems are installed without such an integrated pressure regulating device, until now it was necessary to completely replace this common valve with a valve with an integrated pressure regulating device.
    [006] From DE 102 56 035 B3 and also from WO 2009/135490 A2 valves with integrated pressure regulation are known for regulating a flow of fluid flowing through the valve. In that case, a pre-set cross section can be modified by means of two moving parts relative to each other and thus the fluid flow can be limited to a maximum value. However, this type of pre-adjustment requires additional installation space on the valve. In existing thermostat valve housings, commercial flows, which are formed without an integrated pressure regulating device, an additional installation space of this type is not available. In these solutions, a new housing, fitted to the corresponding components, is required and therefore installed.
    [007] From DE 10 20007 050 454 B4, particularly from the images according to Figures 3 and 4, pre-adjustable flow regulating valves are known, in which the pressure regulating device is arranged as a separate component below the throttle body and matching seat. Also in this case, additional installation space is required. Mounting on existing thermostat valve housings, commercial flows, without a pressure regulating device is also not possible in these embodiments. Therefore, also then a completely new housing, fitted to the components, has to be used.
    [008] From document DE 102 56 305 B3 and from document WO 2009/135490 A2 are furthermore known valves with integrated pressure regulation for regulating a fluid flow flowing through the valve, in which the theoretical value spring is arranged in the flow channel of the fluid flow. Furthermore, a valve spring is arranged on the valve stem. These solutions require, in each case, a new housing, adjusted to the use of a special valve. Furthermore, in these solutions the theoretical value spring is arranged in the flow channel of the fluid flow, which, on the one hand, narrows the cross-section of the flow channel and, on the other hand, influences the flow in the flow channel by the formation of turbulence, which is reflected in a disturbing way, especially in higher volume flows.
    [009] A similar arrangement is also known from document DE 10 2007 050 454 B4.
    [0010] Based on this state of the art, the invention is based on the task of creating a flow regulating valve, with integrated pressure regulation, to be produced at a favorable price, which is simply constructed, requires the least possible space and which offers the possibility of equipping existing thermostat valves with a corresponding configuration of the flow regulating valve, in which the non-dynamic valve fittings are replaced by a valve according to the invention.
    [0011] To solve this task, the invention proposes that the flow regulator unit, which consists of a first throttling device, which is formed by a first butterfly body fixed to the stem and a seat, and a second throttling device, consisting of a second throttle body, arranged on the stem, adjustable along it, and a seat, the second throttle body being movable towards and away from the first throttle body, thereby the cross section of the flow channel can be modified by the flow regulating valve.
    [0012] According to this configuration, the flow regulating unit is formed in a very compact way and has all the necessary components. In this case, it is therefore an independent flow regulator unit, which can be mounted in a corresponding housing.
    [0013] In this case, it is particularly preferred that the first throttle body forms the seat of the second throttle body.
    [0014] A very special configuration is seen in the fact that all parts, namely, the pressure regulating device, the valve stem, with first butterfly body, the flow regulating unit, with first throttling device and second Throttling device, together with the second throttle body and the corresponding seats for the throttling bodies, such as valve trim, are combined for a mounting unit, which can be mounted to the housing connection nozzles as a unit or disassembled from the same. , where the individual parts are connected to each other loss-proof.
    [0015] In particular, this creates the possibility of equipping the housing with such a valve trim, which comprises all the elements of pressure regulation and flow regulation. This valve trim is designed as a mounting unit, which in its entirety can be mounted on or removed from the corresponding housing. It also presents the possibility of retrofitting existing thermostat valves, which are on the market, with non-dynamic valve gaskets, with a dynamic valve gasket of this type, in which the existing valve gasket is replaced by the valve gasket according to the invention.
    [0016] In the configuration according to the invention, on the actuating part of the valve stem, which protrudes from the housing, an adjustment actuation can be fastened to the housing, by means of which the adjustment of the first throttling device occurs. By the adjustment drive, the valve stem is transferred axially, against a spring provided in the valve trim or in the retaining contour, from a position of maximum opening to a position of partial or complete closing.
    [0017] To enable a simple adjustment of the second choke device, it is provided that the rod preferably has, in its terminal region, which projects from the housing or valve trim, a handling device installed in it rigidly to the torsion, for adjustment of the second throttle device, the second throttle body being coupled to the stem via a threaded connection and the second throttle body is retained or rigidly guided to twist in a component of the valve trim or from the seat to the first throttle body, adjustable parallel to the longitudinal extension of the stem.
    [0018] In this case, it is preferably provided that the handling device is releasably retained on the rod.
    [0019] It may also be preferred that the handling device is formed as a polygon and forms an engagement contour for an adjustment wrench.
    [0020] To indicate to the user the position that he actually adjusted by the adjustment, it is preferably provided that the handling device is provided with first markings for the adjustment position and a second marking is arranged on the housing or valve trim corresponding to it.
    [0021] A preferred configuration of the pressure regulating device is seen in the fact that the pressure regulating device has a membrane fixedly retained in a hollow space of the valve trim, whose side facing the actuating portion of the stem is at open line communication with the input via a first channel formed in the stem and which side remote from the flow regulating unit is in communication via a second channel to the flow regulating unit.
    [0022] By this configuration, it is obtained in a simple way that the pressure difference between the pressure regions before and after the flow regulator unit is kept constant.
    [0023] In addition, to solve the initially proposed task, it is proposed to have a valve trim, which can be inserted or is inserted in the connection nozzles, with a pressure regulating device integrated in it, controlled by membrane, which it coaxially surrounds the stem and is axially displaceable over it, which maintains constant the pressure difference between the pressure regions before and after the flow regulating unit integrated in the valve trim, which consists of the valve seat and the butterfly body, being that the stem integrated in the valve trim has a drive part, which protrudes from the housing and valve trim and has the throttle body fixed on it, and that the preliminary adjustment of the flow regulating unit takes place by means of of adjustable throttle body lift limiting means.
    [0024] According to this configuration, the flow regulating unit of the flow regulating valve is formed in a very compact way and has all the necessary components. In this case, it is therefore an independent flow-regulating unit, which can be mounted in a corresponding housing, therefore particularly also in a housing, which has hitherto received non-dynamic valve gaskets, which can be replaced by the valve. flow regulator according to the invention.
    [0025] Due to this configuration, the corresponding valves can therefore be mounted in existing thermostat valve housing, commercial flows, and by the specified compact external measurements, a very small immersion depth is obtained in the housing of thermostat valve, so the geometries of the existing pipe connections of the housing are not covered by the valve trim and this solution allows you to mount or remove the component as a unit in a thermostat valve housing.
    [0026] According to the invention, the flow regulating unit is substantially formed by a valve seat and a butterfly body, and the preliminary adjustment of the flow regulating unit is obtained by means of a body elevation limitation throttle so that fluid flow can be limited to a maximum value, which corresponds to the lifting height of the throttle body. In addition, the pressure regulating device surrounds the rod coaxially coupled with the throttle body and is axially movable thereon, so that a compact unit is formed, which can also be mounted as a mounting unit in housings. existing thermostat valve, flows in trade, and dismantled from it.
    [0027] In this case, it is particularly preferred that the pressure regulating device and the flow flow regulating device, together with the lifting limiting means, as valve trim components, are connected to each other, proof against loss, for a mounting unit, so that the valve trim can be mounted as a complete mounting unit on or dismounted from the housing.
    [0028] In this way, both the compact form of construction and the possibility of handling are additionally favored.
    [0029] A preferred enhancement of the elevation limitation is seen in the fact that the stem has at least one collar or shoulder, which projects radially, which corresponds to a stop in an adjustment ring held axially in the valve trim. movable in relation to the valve trim, and in a terminal position it rests against the stop.
    [0030] In addition, in this case, it is provided that the axially movable adjustment ring coaxially surrounds the rod.
    [0031] Preferably, it is also provided that the adjustment ring has a thread, which cooperates in terms of thread with a threaded formation of the valve trim, whereby a rotary movement of the adjustment ring is converted into a movement of axial elevation.
    [0032] In particular, it is also provided that the adjustment ring is provided with a manual operating wheel rigidly coupled to the torsion with it, which presents a scale with readable preliminary adjustment values, which correspond with an indicator fixed on the gasket of valve.
    [0033] Finally, it is provided that the turning movement of the manual maneuver wheel is limited by a stop provided in the manual maneuver wheel, corresponding to the indicator.
    [0034] Due to these characteristics, an excellent handling for adjusting the elevation of the throttle body is obtained partially or completely and, thus, a simple way of the adjustable elevation limiting means is made available.
    [0035] In order to enable and facilitate the arrangement of maneuvering pieces, by means of which the stem can be maneuvered, i.e., displaced in the axial direction, it is proposed that the valve trim has a valve trim housing that has a connecting geometry for fastening adjustment members, which act on the actuating part of the rod.
    [0036] In order to keep the internal space of the fitting free from impurities, it is preferably provided that the valve seat of the valve fitting has a filter sieve.
    [0037] In this case, provision can also be made for the filter sieve to be releasably attached to the valve insert or components thereof.
    [0038] To create a generic type flow regulating valve, in which the installation of the necessary elements can take place in a thermostat valve housing, and despite the compact external dimensions specified in this way, a larger volume flow as possible, it can run through the flow regulating valve and being ensured that, despite the assembly of the corresponding parts, the internal space of the valve housing remains free in the region of the pipe connection geometries, therefore it is not covered by assembled elements, it is proposed. if a valve gasket is arranged, which can be inserted or is inserted in the connection nozzles, with a pressure regulating device, controlled by membrane, integrated therein, which surrounds the stem coaxially and axially displaceable over it, which maintains constant the pressure difference between the pressure regions before and after the flow regulating unit integrated in the valve trim, which consists of the as valve seat and throttle body, with the stem integrated in the valve trim having a drive part that protrudes from the valve casing and trim and the throttle body fixed thereon, which comprises a theoretical spring of the pressure regulating device on the side away from the flow channel or membrane slit or on the side facing the actuating portion of the stem, and that a valve spring coaxially surrounds the set spring.
    [0039] According to the invention, to perform a hydraulic adjustment in a fluid-conducting heating or cooling system, a valve with an integrated pressure regulating device is installed on the individual consumers. As the plurality of valves in existing systems are installed without an integrated pressure regulating device, it is advantageous when, according to the invention, in these valves only the valve insert is replaced by a valve insert with an integrated pressure regulating device. This is possible, for example, by means of assembly chambers, even under system pressure. In this way, in existing systems, a hydraulic adjustment with little complexity is possible. Furthermore, because the theoretical value spring is arranged on the side of the membrane away from the flow channel and it is arranged coaxially between the valve spring and the operating rod, in compact external dimensions it is nevertheless placed the largest possible volume flow is available, the flow being unaffected by the theoretical value spring.
    [0040] Particularly preferably, it is provided that the pressure regulating device and the flow flow regulating device, with the valve spring and the theoretical value spring as components of the valve trim, are connected to each other, in a non-reactive manner. loss, for a mounting unit, so that the valve trim can be mounted as a complete mounting unit in the housing or dismounted from it.
    [0041] This favors both the compact form of construction as well as the ease of handling.
    [0042] In addition, it is preferably provided that both the theoretical spring and the valve spring are supported on a common support element located in the valve insert.
    [0043] Also in this way, the compact form of construction is favored, which allows the assembly in existing valve housings.
    [0044] Preferably, in this case, provision is made for the support element to further form a contour supporting the membrane, which forms a mounting space for the outer sealing edge of the membrane.
    [0045] In addition, it can preferably be provided that the support element has a connection by frictional union or positive engagement with the valve trim housing.
    [0046] It can also be provided that the valve trim or the valve trim housing is provided with a connecting geometry for fixing adjustment members acting on the actuating part of the valve stem.
    [0047] In addition, it is preferably provided that the seat of the valve insert has a collar.
    [0048] A particularly preferred improvement is seen in the fact that on the valve trim seat, below the first throttle body, a second pre-adjustable throttle body is arranged.
    [0049] In this way, the possibility of pre-adjusting the flow is realized in a simple way, without the construction size of the valve trim being enlarged.
    [0050] To prevent impurities, it is also provided that the valve fitting seat has a filter sieve.
    [0051] In this case, it can preferably be provided that the filter sieve is interchangeably arranged.
    [0052] Examples of embodiments of the invention are represented in the drawing and described in more detail below.

    [0064] Figure 11 is a variant of a valve trim with separate pre-adjustment element and connection geometries for fastening an adjustment drive, which can act on the stem.
    [0065] In the drawing is shown a flow regulating valve 1 for liquid-conductive heating or cooling systems. It consists of a housing 2, in one or more parts, which in the example of the modality has an inlet 3 and an outlet 4. Between inlet 3 and outlet 4, connection nozzles 13 are provided, in which a pressure regulating device is mounted, which maintains constant the pressure difference between the pressure regions before and after a flow regulating unit 8 arranged in housing 2. In addition, a stem is arranged, in the manner of a valve stem, which has an actuation part that it protrudes upwards, out of frame 2. An adjustment drive can be mounted on frame 2, and the frame has a connection possibility 6 for connecting this adjustment drive. The adjustment drive acts on the upper end of the rod 7and thus on the flow regulating unit or part of it. Thereby, the flow channel is modified in cross-section by the valve or valve trim, still to be described later. The pressure regulating device 14 surrounds the rod 7 coaxially and is arranged axially movable thereon.
    [0066] The rod 7 contains at its lower end as a component of a first throttling device, a first throttle body 9, which determines the flow. In particular, the flow regulating unit 8 consists of a first throttling device with the first butterfly body 9 fixed to the rod 7 and a seat 10 associated thereto. In addition, the flow regulating unit 8 consists of a second throttling device, which is formed by a second butterfly body 11 adjustablely disposed along the rod 7 and a seat associated with it. The second throttle body 11 is movable towards the first throttle body 9, and away from it. Thereby, the cross section of the flow channel can be modified by the flow regulating valve 1.
    [0067] In particular, in this case, it is also provided that the first throttle body 9 simultaneously forms the seat for the second throttle body 1. For example, in Figure 1 a position is shown on the right in which the corner of the edge of the second throttle body 11 abuts hermetically against the underside of the first throttle body 9. In the drawing figure on the left it is shown that the second throttle body 11 leaves distance from the first throttle body 9, so that it is possible a flow through a slit 5 to the output 4.
    [0068] As also particularly shown in Figure 2, all parts, i.e. the pressure regulating device 14, the valve stem 7, with its first butterfly body 9, the flow regulating unit 8, with the first choke device and the second choke device together with the second throttle body 11 and the corresponding seats for the choke bodies like valve trim 5, are combined to a mounting unit, which as such can be inserted and assembled completely into the connection nipples 13 of frame 2 as a complete unit.
    [0069] The individual pieces are connected, in this case, to each other loss-proof. This configuration also makes it possible, among other things, to carry out an exchange in thermostat valves, which are on the market, with non-dynamic valve trims, in which the existing valve trim is exchanged for the valve trim 5 according to the invention.
    [0070] The rod 7 has in its terminal region that protrudes above the housing 2 or the nozzle 13 or the valve trim 5, a handling device installed therein rigidly to torsional, for adjustment of the second throttling device. The second butterfly body 11 is for this purpose coupled with the stem 7 via a threaded coupling 16. In addition, the second butterfly body 11 is releasably and rigidly retained and guided to twist in a component of the valve trim 5 or of the seat 10 for the first throttle body 9, parallel to the longitudinal extension of the stem. Therefore, by rotation of the rod 7, it is possible to adjust by means of the handling device 12 the second butterfly body 11 in the direction of the longitudinal extension of the rod.
    [0071] Preferably, the handling device 12 is releasably retained on the rod 7. It is also preferred that the handling device 12 is formed as a polygon and thus forms an engagement contour for an adjustment wrench, for example , a screwdriver.
    [0072] Additionally, it is provided that the handling device 12 is provided with first markings for the adjustment position and on the housing 2 or, preferably, on the valve trim 5, a second marking corresponding thereto is provided. Thus, it is possible, in a user-friendly way, to exactly set the preset values and read them.
    [0073] The pressure regulating device 14 is configured in a manner known per se. To this end, in a hollow space of the valve trim 5 is held a membrane 17, whose side facing the actuating part of the stem 7 (above in the drawing) is in open line communication with the inlet 3 through a first channel 18 formed in the stem 7. Its side facing the flow flow regulating device 8 is in communication through a second channel 19, which is open to the flow regulating unit 9. In this way, the pressure regulation is integrated with simple way in setting the valve trim 5.
    [0074] The invention makes available a flow regulating valve 1, which with the valve trim 5 with all functional components creates the possibility of producing these parts, in small dimensions, at favorable prices. In particular, these 5 valve trims can also be exchanged against conventional valve trims on common thermostat valves.
    [0075] In the drawing, particularly in Figures 3 to 8, there is shown a flow regulating valve 1 for liquid-conductive heating or cooling systems. It substantially consists of a housing 2 of one or multiple parts, which has an inlet 3 and an outlet 4. Between the inlet 3 and the outlet 4, connection nozzles 13 are provided, on which a pressure regulating device is mounted. 13, in which a pressure regulating device 14 is mounted, which maintains constant the pressure difference between the pressure regions before and after a flow regulating unit 8. In addition, a rod 7 is arranged in the manner of a rod. of valve, which has a drive part 7, which protrudes upwards out of the frame 2. An adjustment drive can be mounted on the frame 2, and the frame has a connection possibility 6, to connect a drive of this type of adjustment. The adjustment drive acts on the upper end 7’ of the stem 7 and thus on the flow regulating unit 8 or parts thereof. Thus, the flow channel is modified in cross-section by the valve or valve trim, yet to be described later.
    [0076] The rod has at its lower end a first throttle body 9, by which the flow is determined. The flow regulating unit with the throttle body attached to the stem 7 and a seat 10 associated therewith. The butterfly body 9 forms with the seat 10 a spacer slit 15, which is open towards the outlet 4, so that a corresponding flow through the valve is possible.
    [0077] As particularly shown in Figures 4, 6 and 8, all the parts, viz. the pressure regulating device 14, the rod 7 with the butterfly body 9 and the flow regulating unit 8 with the seat as valve trim 5, they are combined for a mounting unit, which as such can be inserted and mounted completely in the connection nipples 13 of the housing as a complete unit. The individual parts are connected to each other, in this case, loss proof. This configuration makes it possible, among other things, to carry out an exchange in thermostat valves, which are on the market, with non-dynamic valve trims, since the existing valve trim is replaced by the valve trim according to the invention. In this valve fitting 5, in addition, the pre-adjustment of the flow regulating unit 8 is integrated, which can be carried out by means of the adjustable lifting limiting means of the throttle body 9.
    [0078] The pressure regulating device 14 is configured in a manner known per se. In this case, and in a hollow space of the valve trim 5, a membrane 17 is fixed, whose side facing the actuating part of the rod 7 (in the drawing, above) is in open line connection with the inlet 3, through of a first channel 18 formed in the rod 7. Its side facing the flow flow regulating device 8 is in communication through a second channel 19, which is open towards the flow regulating unit 8. Thus, in a simple manner, the regulation pressure is integrated in the valve trim configuration 5.
    [0079] The valve trim 5 has particularly compact external measurements and, therefore, a immersion depth as low as possible in the thermostat valve housing 2, so that the connection geometries of the tubes 13 of the housing 2 are covered by the trim of valve 5, when the valve trim 5 is mounted as a unit in the housing or removed from it.
    [0080] By limiting the elevation of the throttle body 9, a pre-adjustment of the flow regulating unit 8 is obtained, so that the fluid flow can be limited to a maximum value, which corresponds to the elevation height of the throttle body 9.
    [0081] The pressure regulator device 14 coaxially surrounds the rod coupled with the butterfly body and is axially movable thereon, so that, in turn, there is a compact unit to be assembled.
    [0082] For the purpose of limiting the elevation, the rod 7 has at least one collar 20 or radially protruding shoulder, which can reach the abutment with a stop 22 mounted on an axially movable adjustment ring 21. The axially movable adjustment ring 21 surrounds the rod 7 coaxially. Additionally, in the example of modality, the adjustment ring 21 is provided with a thread 23, which converts the rotational movement into a lifting movement. In addition, the adjustment ring 21 is provided with a manual maneuver wheel 24 rigidly coupled to the twist therein. This manual maneuver wheel 24 has a scale 25 for reading the preset values, which corresponds to an indicator 26 installed in the valve trim 5. The rotary movement of the manual maneuver wheel 24 is limited by a stop 27 formed on the wheel. manual maneuver 24 and corresponding to indicator 26. In addition, the valve trim housing 28, as shown in Figure 8, can be provided with a connection geometry 29 for fixing adjustment members, which act on the part of activation 7 of rod 7.
    [0083] For the purposes of the elevation limitation, corresponding elements can be adjusted, as seen in the drawing figures, for example, to a position according to Figure 4, which defines a large preset value and thus a large elevation of the throttle body 9 or else, as shown in Figure 6, the elevation limitation can be correspondingly adjusted to form a small preset value. Also, as shown in Figure 8, the valve trim may be formed with a separate pre-adjustment element and connection geometries 29 for attaching an adjustment drive.
    [0084] Additionally, to avoid impurities that could impair the function of the valve trim, it is provided that below the valve seat 10 of the valve trim 5 a filter sieve 30 is provided, which is optionally detachably fixed, therefore exchangeable.
    [0085] Particularly by forming the lifting limiting means for lifting the butterfly body, a particularly compact form of construction of the valve insert 5 is promoted, so that this valve insert 5 can be exchanged for conventional valve inserts in conventional thermostat valves.
    [0086] In the drawing (Fig. 9 to 11) a flow regulating valve 1 for liquid-conducting heating or cooling systems is shown. It consists of a housing 2 in one part or in multiple parts, which in the example of the modality has an input 3 and an output 4. Between input 3 and output 4, connection nozzles 13 are provided, in which a flow regulating device is mounted. flow 14, which maintains constant the pressure difference between the pressure regions before and after a flow regulating unit 8 arranged in housing 2. Furthermore, a stem 7 is arranged in the manner of a valve stem, which has a part. of drive 7', which protrudes upwards from the housing 2. On the housing 2, for example, an adjustment drive can be mounted, and the housing 2 has a connection possibility 6 for connecting this adjustment drive. Such an adjustment drive acts on the upper end of the stem 7 and thereby on the flow regulating unit 8 or parts thereof. With this, the flow channel through the valve or the valve trim, still to be described later, is modified in cross-section.
    [0087] The rod 7 carries at its lower end as a component of a first throttling device a first butterfly body 9, which determines the flow. In particular, the flow regulating unit 8 consists of a first throttling device, with the first throttle body 9 fixed to the rod 7 and a seat 10 associated thereto. Furthermore, the flow flow regulating device consists of a second throttling device, which consists of a second throttle body 11, arranged axially adjustable on a collar 39, and which is associated with the throttle body 9. Depending on the adjustment of the second butterfly body 11, relative to the first butterfly body 9, the cross section of the flow slot 15 can be changed.
    [0088] All parts, viz., the pressure regulating device 14, the valve stem 7, with its butterfly body 9, the flow regulating unit 8, with the first throttling device and the second throttling device, together with the second throttle body 11 and the corresponding seats for the choke bodies are combined as a valve unit for an assembly unit, which, as such, can be inserted completely into the connection nozzles 13 of the housing as a unit and assembled or also disassembled. The individual parts are connected, in this case, to each other, loss-proof. This configuration also makes it possible, among other things, to exchange thermostat valves, which are on the market, with non-dynamic valve trims, as the existing valve trim is exchanged for valve trim 5 according to the invention.
    [0089] The pressure regulating device 14 integrated in the valve trim 5 is configured in a manner known per se. To this end, in a hollow space of the valve trim 5 a membrane 17 is held fixed, whose side facing the actuating part of the stem 7 (in the drawing, above) is in open line connection with the inlet 3, through of a first channel 18 formed in the rod 7. Its side facing the flow flow regulating device 8 is in communication through a second channel 19, which is open towards the flow regulating unit 8. Thus, in a simple manner, the regulation pressure is integrated in the valve trim configuration 5.
    [0090] Furthermore, a spring of theoretical value 32 of the pressure regulator device 14 is arranged on the side of the membrane 17 away from the flow channel or slit 15 and the side facing the drive part 7' of the rod 7. In addition Furthermore, a valve spring 33 is arranged, which coaxially surrounds the set spring 32. In this way, the mounting space for the two springs is kept small, so that the compact constructional shape of the valve trim is achieved and it is obtained that it can be mounted on existing valve housings of the type indicated above.
    [0091] Particularly, therefore, the pressure regulating device 14 and the flow regulating unit 8, together with the valve spring 33 and the theoretical value spring 32 are connected to each other as components of the valve trim 5, proof against loss, for a mounting unit, so that the valve trim 5 can be mounted as a complete mounting unit in the housing 2 or dismounted from it.
    [0092] In the example of embodiment, both the theoretical spring 32 and the valve spring 33 are supported on a common support element 34, which is located in the valve insert 5, which is favorable for the shape. of compact construction. This support element 34 further forms a contour 35, which supports the membrane 17, and which forms a mounting space 36 for the outer sealing edge 37 of the membrane 17. The support element 34 is connected by a frictional connection or positive engagement 38 with the valve trim housing 28. In the example of embodiment according to Figure 11, the valve trim 5 or the valve trim housing 28 has a connection geometry 29 for fastening adjustment members , which can act on the actuating part 7' of the valve stem 7.
    [0093] In addition, the seat 10 of the valve trim 5 has a collar 39. In that collar a second butterfly body 11 is pre-adjustable below the first butterfly body 9 which is pre-adjustable. Appropriately, it is axially adjustable, for example, by rotating the rod 7 coupled with the body and throttling 11.
    [0094] Additionally, the valve trim seat 5 is equipped on its underside with a filter sieve 30, which is preferably arranged interchangeably.
    [0095] The invention is not limited to the modality examples, but is multiple-mode variable within the scope of the declaration.
    [0096] All individual or combination characteristics stated in the description or in the figures are considered to be essential to the invention.
