    15 20 25 setting the max genom flow through the valve, ie the Kvs value. The valve knob in this solution is only a presetting tool, which after performing presetting is removed from the valve.
    The older solutions have a number of disadvantages. A disadvantage is that you need special presetting tools in the form of Allen keys, special knobs or the like for, for example, the presetting of the valve. These must first be delivered separately with the valve delivery, so that later, after commissioning of the system, with for example pre-setting of the control valve, they are taken care of and stored until the next time an adjustment of the valve's operating setting is needed. Another disadvantage is that when the valve type is a control valve, it is usually fitted with a mounted and motorized damper actuator, and then the presetting must take place before the actuator is mounted, and this must consequently take place on site in connection with commissioning and only then can the actuator mounted on the valve. Older solutions also have the disadvantage that fl your various actuators are needed to achieve fl your various functions, for example presetting and shutting down, ie an actuator for each function. Furthermore, these actuators are handled in different ways, for example rotated and displaced, respectively, in order to effect corresponding rotational and displacement movements of the different throttling members of the valves, which are arranged for each function. For example, there are such solutions where a special presetting tool is operated to effect an axial movement of a throttle member, while a valve knob is operated to rotate / rotate another throttle member, for example a ball or veil to close the valve through the valve. 10 15 20 25 Description of the invention In the present invention, the above problems have been solved, by providing the presettable control valve with only one actuator, which is arranged to surface both a first throttling member in the form of an inner cone, and a second throttling member in the form of an outer cone, axially in the direction of and from the valve seat of the control valve, respectively. This is thus achieved with a single actuator and only with one type of movement, preferably rotation of the actuator. This has the advantage that only one actuator needs to be handled in order to achieve all the functions included in the valve, and that the handling of said actuators is always done in the same way, preferably rotation, in order to achieve all functions.
    According to a preferred embodiment of the invention, the two throttling members, the inner cone and the outer cone, respectively, are moved axially towards the valve seat, when the actuator is rotated in a first operating position, which constitutes the shut-off position of the control valve. When the flow opening of the valve for fl uid fl fate is completely spared by the outer cone, fl uid fl fate ends through the control valve. As both the inner and outer cones are moved at the same time in this position, the presetting of the valve will not be affected by the closing movement, which is an advantage, since the valve does not need to be preset again after it has been closed.
    By rotating the actuator in a preferred second operating position, which constitutes the presetting position of the control valve, only the inner cone is moved axially in the direction of or from the valve seat, whereby the control valve is preset. This second operating position is clearly different from the first operating position so that the operator knows with certainty that the actuator when rotating in this second position only performs the presetting function. The advantage over older solutions is still that all functions of the control valve are performed with one and the same actuator and with the same handling, namely rotation.
    In a preferred embodiment, the actuator is slidably arranged between different positions, in which different functions can be performed. The actuator is preferably arranged around the valve spindle, but freely axially movable and rotatable relative thereto. A valve spindle is a shaft in which the regulating part, usually a cone, is coordinated with a damper actuator mounted on the control valve for motorizing the control function of the valve. The functions performed in the different modes are according to the preferred embodiment normal mode / control mode, presetting and shutdown but are not limited to only these functions but can be completely different functions, depending on needs and valve type. According to the invention, the actuator is advantageously mounted from the factory and arranged so that it never has to be removed from the valve, whether it is to be provided with an actuator or not. Consequently, the "tool" is always found on the valve upon delivery, during commissioning and all time thereafter.
    The advantages are then that service personnel do not have to spend time looking for missing tools of all possible different variants and furthermore that the handling / maneuvering of the valve is facilitated as all functions can be performed with one and the same actuator. Furthermore, it is entirely possible to deliver an attached actuator, mounted under factory efficiency instead of being controlled by an on-site installation, with increased costs for installation and poorer working environment conditions. The installation time is thus significantly shortened.
    The design is not limited to only this type of control valve, but can advantageously be applied to a number of different types of valves where a stationary tool is desired arranged for different functions.
    According to a further preferred embodiment of the invention, the actuator is rotatable in any position along its axis of rotation, in and between the end positions of the actuator 10. This means that the number of functions is not limited by the possible position positions of the actuator, but the valve itself can be provided with the number of functions that are technically possible from a valve construction point of view and that are needed. Nonnally and in the current situation, the need for function modes is usually in the order of 2-3, but the increase is not limited to this number, but the function modes can be fl er. Older solutions usually include a function mode where the preset tool is used.
    According to a preferred embodiment, the invention comprises two operating positions, a first remote position end position in relation to the valve housing and a second end position closest to the valve housing. The actuator is then displaceable between these two end positions and rotatable in the respective position. With one and the same actuator, which in addition, as mentioned above, is always available, two function modes are thus obtained, in which any function can be included.
    According to a preferred embodiment, the invention comprises a resilient member, preferably a return spring. In its mounted position, the resilient member has a clamped force directed substantially towards the first distal end position of the actuator in relation to the valve housing and which force is transmitted either directly or indirectly to the actuator. As a result, the actuator always returns to its first distal end position, which can also be called its original position or normal position. In this way it is ensured that the function provided in this original position or normal position is always available except when a larger, substantially opposite force acts on the actuator, for example pressing the actuator in the direction of the valve housing by hand force. In the same way, the advantage is obtained that this first remote position becomes distinct and the "operator" knows with certainty that the control valve is in its first functional position, after which, for example, the actuator is rotated and the function is performed in one way or another. According to a further preferred embodiment, the actuator is only displaceable to its second end position, closest to the valve housing, by an applied external axial force substantially in the direction of the valve housing. This force is for practical reasons usually in the form of manual force where the "operator" pushes the actuator in the direction of the valve housing, and when the end position is reached the arranged function is available, and preferably the actuator is rotated in this position to perform the function. Some known solutions have problems finding the right position for the presetting tool, for example, and it can be difficult to access at the right angle, for example with an Allen key and also difficult to access to see what you are doing. In combination with poor lighting around the control valve, it is even more difficult to perform the steps. These two distinct positions of the invention eliminate these difficulties.
    In a preferred embodiment of the invention, the first distal end position of the actuator comprises relative to the valve housing, the control position of the complete control valve. In this position the actuator is freely movable and rotatable relative to the valve stem, which makes the control of the valve possible when the actuator is in this position. A motorized actuator mounted on the control valve engages the valve stem and the actuator communicates with sensors in the ids uid system and receives signals as to whether the load / power take-off varies in the part that the current control valve regulates, after which the throttle actuator moves the spindle or axially. valve seat, depending on whether the need for fate increases or decreases. The spindle in turn is in engagement with the valve's regulating cone, the inner ball, which is arranged to regulate the fate through the valve. According to the invention, the regulation takes place in that the inner ball comprises an opening with a specific geometry, which opening cooperates with the valve seat which shields the opening more or less depending on the load. In the first remote position of the actuator, ie the control position of the complete control valve, the actuator is in a rest position. The actuator 10 15 20 25 is only used when there is a need for manual handling, in connection with commissioning, inspection or, for example, shutting down all or parts of the system.
    In a preferred embodiment of the invention, the second end position of the actuator, closest to the valve housing, comprises the preset position of the complete control valve. In this position, the actuator is also freely movable and rotatable relative to the valve stem, whereby the valve stem is not affected by the movement and rotation of the actuator. By pressing the actuator in the direction of the valve housing, to its end position in this direction, the actuator engages with cooperating parts in the valve housing and the valve neck whereby a rotational movement of the actuator in this position is transmitted to an axial movement of an inner cone, which is arranged to be preset in a position relative to the valve seat so that the desired maximum fl uid fl fate through the valve, i.e. the desired Kvs value, is obtained. Because a preferred form of the device comprises a clamped force fi, preferably a return spring, which acts on the actuator, the actuator always returns to its first distal end position, its normal position after the pressing force has been removed. An advantage of this arrangement is that the position for presetting is very clear as it is an end position, in which a simple grippable actuator is arranged to perform the function instead of using Allen keys and the like in older solutions.
    In a preferred embodiment of the invention, the first distal end position of the actuator relative to the valve housing also includes the shut-off position of the complete control valve. In this position, as previously described, the actuator is freely movable and rotatable relative to the valve stem, which makes the control of the valve possible when the actuator is in this position. By the actuator in this position gripping cooperating parts in the valve housing and the valve neck, a rotational movement of the actuator in this first distal end position is transmitted to the cooperating parts so that they act on an outer cone arranged in the valve neck. The outer cone is slidably arranged in the valve neck between a position at a distance from the valve seat and that another position adjacent to the valve seat and when the actuator is rotated in its first distal position the movement is transmitted to the outer cone which is displaced axially towards the valve seat to completely cut off both inner cone opening and a flow opening in the valve housing. The flow opening is arranged in close proximity to the valve seat. Since the actuator preferably comprises a return spring or the like which ensures that the actuator returns to this first distal end position when no external force (hand force) affects it, the shut-off function is always available with the complete control valve, in this position. Thus, the valve does not have to be set manually in this position to be able to perform this function and the valve is always possible to close completely for the flow of fl uid regardless of whether it is equipped with a single actuator or not.
    According to a preferred embodiment of the invention, the actuator is preferably a valve knob. The valve knob itself is well known in all forms of valves in HVAC technology, which is an advantage for adjustment / operating personnel who are then well acquainted with this tool and how it is handled. Older solutions have, as mentioned earlier, various different types of more or less custom-made tools for, for example, presetting the Kvs value or other functions.
    These tools often have to be inserted into a designated groove, sleeve or other instructions, often partially hidden or difficult to access. As the valves are usually mounted on pipes in suspended ceilings or in shafts, the lighting around the valve is substandard, which further complicates the use of special tools or Allen keys or the like, where adjustment / operating personnel must then try to find the right position for the tool. A sturdy and easily gripable valve knob clarifies and simplifies the adjustment of the valve: and this valve knob is advantageously provided with some form of scale or other clear indication indicating the operating modes / settings of the valve.
    This achieves both previously known advantages together with the new advantages and in one and the same valve, has been obtained: - A single actuator for all functions in the valve, which in the preferred embodiment are presetting, shut-off and control.
    - The valve preset does not change when the genom uid fl flow is switched off through the valve.
    - A single actuator / tool which is advantageously mounted on the valve from delivery, during operation and for the entire life of the valve.
    - Faster installation and improved installation ergonomics and thus lower installation costs as the pre-setting tool / shut-off tool / actuator is always mounted, and the valve is advantageously also delivered with mounted actuator.
    The constructive design of the present invention is described in detail below. In addition, the invention further advances the state of the art in the field in various respects. This is realized in the present invention in that a device of the type described below is substantially of such a nature as appears in the characterizing part of claim 1.
    Further features and advantages of the invention will become apparent from the following description taken in conjunction with the accompanying drawings, which show a preferred but non-limiting exemplary embodiment of the invention.
    Brief description of the figures In detail represents in diametrical, partly schematic cross-sections or perspective views: - Fig. 1 shows the actuator in its first, distal end position (a), in relation to the valve housing.
    Fig. 2 shows the actuator in its second end position (b), closest to the valve body. Detailed description of the figures Fig. 1 shows a complete control valve 1 comprising an actuator 10, preferably a valve knob, in its first operating position, a first distal end position (a), in relation to a valve housing 2 of the complete control valve 1, and this first operating position constitutes the shut-off position of the control valve.
    The actuator 10 is arranged on the valve neck 5 of the complete control valve 1, which connects at an angle to the valve housing 2 of the control valve. The valve neck 5 comprises a valve insert 9 whereby a valve spindle 11 is preferably centrally mounted. The complete valve insert 9 also comprises a sleeve-shaped and cylindrical inner cone 13 for regulating and presetting the valve's selectable Kvs value, which inner cone is fixedly arranged with the valve stem 11 and the inner cone has an open bottom for inflow of fl uid and an opening 14 at its fl ank, for outflow of fl uid. Furthermore, the complete valve insert 9 comprises a sleeve-shaped and cylindrical outer cone 15, which partially encloses the upper part of the inner cone 13 and this outer cone is arranged for, among other things, shutting off the flow through the complete control valve 1. The cylindrical outer cone 15 is slidably arranged in the valve. 13 and the outer cone 15 displaceable relative to each other. The complete control valve 1 also comprises an inlet connection 3 and an outlet connection 4 and a flow opening 7 located in the lower part of the valve neck 5 adjacent to a valve seat 6, and two connections for measuring nipples 8. During operation the fluid flows through the valve from the inlet connection 3 via the inner cone 13. through its bottom and further out through the opening 14 of the inner cone, then further through the flow opening 7 and then to the outlet connection 4.
    In the first, distal end position (a), the top of the actuator 10 connects to an adapter 18 which is fixedly mounted to the complete valve insert 9. The adapter 18 is arranged to function as a bracket for a mounted actuator, which is not shown.
    Since the top of the actuator 10 connects to the adapter 18, a distinct distal end position is obtained for the axial movement of the actuator along the valve stem 11.
    Regardless of the position, the actuator 10 is always freely axially movable and rotatable in relation to the valve stem 1 1.
    In the first, distal end position (a), which constitutes the first operating position of the control valve, the actuator 10 is via teeth, arranged at the inside of the actuator (not shown), in engagement with two toothed intermediate gears 19,21 which in turn engage with a shut-off screw 16 and a presetting screw 17, respectively. By a rotational movement of the actuator 10 in this first operating position, the rotational movement is transmitted to the rotatable and geared intermediate gear 19, arranged for the shut-off function. This intermediate gear 19 is in turn engaged with a rotatable and toothed so-called sol 22, which in turn is engaged with the shut-off screw 16. Upon rotation of the actuator 10, the rotational movement is thus transmitted to the shut-off screw 16, which by a threaded joint 23 transmits the rotational movement to an axial movement of the preset screw 17.
    The presetting screw 17 is fixedly arranged with the outer cone 15 and therefore the outer cone 15 will also be moved axially and together with the inner cone 13. To close the valve 1 completely for flow, the outer cone 15 is moved axially towards the valve seat 6 until the entire flow opening 7 is completely cut off by the outer cone 15. Thus, a shut-off function is obtained and this function is operated with the actuator 10 in its first operating position, the first, far end position (a).
    The first, far end position (a) also includes the control position of the complete control valve 1. As described above, the actuator 10 is freely rotatable relative to the valve stem 11, which means that the control function of the valve is not affected by any axial movement or rotation of the actuator 10 and not the other way around, that the control affects the actuator 10 in this position. An mounted actuator, not shown, communicates with sensors in the system where the complete control valve 1 is included and the actuator, which is in engagement with the valve stem 11, moves it axially in the direction of or from the valve seat 6, depending on load and need for increased or decreased fate. The opening 14 of the inner cone 13 is thus more or less shielded by the valve seat 6, whereby the fate through the valve changes. Thus, when the actuator 10 is in its first, distal end position (a), the preferred embodiment includes two valve functions - control and shut-off. However, it is quite possible according to the invention that completely different functions are included in this position, depending on the type of valve on which the actuator is mounted.
    The invention also comprises a resilient member, preferably a return spring 12 which is arranged to return the actuator 10 to its first, distal end position (a).
    In its mounted position, the return spring 12 has a clamped force directed substantially towards the first distal end position (a) of the actuator 10 relative to the valve housing 2 and the collar is transmitted indirectly to the actuator 10. Thereby the actuator 10 always returns to its first distal end position (a) and in this way it is ensured that the action / functions, which are arranged in this position, are always available in all cases except when an externally applied, opposite force fi, for example hand force, acts on the actuator 10 by pressing the actuator in the direction of the valve housing 2. If the actuator 10 is pressed against the valve housing 2, the actuator assumes its second end position (b).
    Fig. 2 shows the actuator 10, preferably the valve knob, in its second actuating position, its second end position (b), closest to the valve housing 2, and this second actuating position constitutes the presetting position of the control valve.
    In order to move the actuator 10 to the second end position (b), which constitutes the second actuating position, the actuator is pressed in the direction of the valve housing 2, for example by hand, the bottom of the actuator 10 connecting to a cover 20, whereby a second distinct function mode enters, a second end position (b), closest to the valve housing 2.
    In the second end position (b), the actuator 10 is via teeth, arranged at the inside of the actuator (not shown), in engagement with a geared intermediate gear 21 which in turn is in engagement with the presetting screw 17. When presetting, the outer cone 15 is found in its uppermost, in relation to the valve seat, remote position.
    The presetting means that the position / distance of the inner cone opening 14 in relation to the valve seat 6 is set.
    By a rotational movement of the actuator 10 in this second end position (b), the rotational movement is transmitted via the intermediate gear 21, which in turn is in engagement with a rotatable and toothed so-called sol 24, which in turn is in engagement with the presetting screw 17 and thus transmitted the rotational movement of the actuator 10 to the presetting screw 17. This is rotatable but does not move axially in the valve neck 5 during the presetting. The lower part of the presetting screw 17 comprises an internal thread which cooperates with an external thread arranged on the upper end of the inner cone 13, and these threads thus form a threaded connection 25, and by the rotation of the presetting screw 17, the rotation is transmitted to an axial movement of the inner cone 13. Thus, for fl, the inner cone is moved axially in the direction of or from the valve seat 6. Note that the outer cone 15 is not affected but remains in its upper position during presetting. When the presetting has been completed and the valve is ready for regulation, the mutual position, given by the presetting, between the inner and outer cones will not change. The inner cone 13 comprises the opening 14 for the flow of fl uid, which opening determines the control characteristics of the complete control valve 1, and by the opening 14 of the inner cone being more or less shielded by the valve seat 6, the maximum valve 14 of the control valve is set in this function, the other end position (b).
    The complete control valve 1 thus comprises a function for pre-setting the Kvs value and this function is available in that the actuator 10 assumes its second operating position, its second end position (b), closest to the valve housing 2. However, it is entirely possible according to the invention to completely other functions are included in this mode, depending on the type of valve on which the actuator is mounted. 10 15 20 25 15 BOME LIST l = control valve 2 = valve housing 3 = connection connection 4 = outlet connection 5 = valve neck 6 = valve seat 7 = flow opening 8 = connection for measuring nipple 9 = valve insert 10 = actuator 1 1 = valve return valve 1 2 = valve spindle 1 2 14 = inncrkäg1ans Opening 1 5 = outer jaw1a 6 6 = shut-off screw 1 7 = front set screw 1 8 = adapter 19 = me11and drive, shut-off 20 = cover 21 = me11and drive, íörinställning 22 = so1, shut-off 23 = threaded connection 24 = soband, iband 25
