Spring gasket for valve housing Field of the Invention
The present invention relates to a valve for regulating a fluid, the valve comprising a valve body, having a central portion and having two connecting ends, said connecting ends extending away from the central portion, and thus indicating a flow direction for said fluid, wherein inside the central part is arranged a valve body comprising a at least partially spherical surface for abutment against a corresponding valve seat, the valve body comprising at least one shut-off part and a flow-through part.
The invention further includes a method of making such a valve. BACKGROUND OF THE INVENTION
It is generally known to manufacture valves, for example ball valves, and thus valve housings in several parts, to then assemble these parts around one or two valve seats and a valve body. Such valves are typically manufactured in brass or in another copper-based alloy and are typically assembled with corresponding threads in the respective parts or alternatively by bolts. In the case of a ball valve, the valve body, as the name implies, is spherical and typically with an outer size larger than the connection openings in the valve body. Such a valve therefore has a valve housing with an internal geometry in which the valve seat and the valve body are placed. The valve body is typically joined in the vicinity of the valve body, requiring the largest internal dimension. Such valves are typically made of molded blanks which are formed and shaped by machining by machining to the desired geometry. However, this process of shaping is quite costly for several reasons. Partly, the individual workpieces must be molded, and partly they must be handled and processed individually in a suitable machining center. Since the individual items are processed individually, this process is time consuming, despite the fact that modern and relatively fast processes are used.
In addition to the molded items being handled and processed prior to assembly around one or two valve seats and a valve body, the material price also plays a major role. Brass or another suitable alloy is expensive and costs significantly more than, for example, ordinary weldable carbon steel.
There is therefore an expressed desire to be able to manufacture valves for both heating and cooling systems, for drinking water and for other purposes, in steel, for example carbon steel or stainless steel, which are partly cheaper than ordinary alloys and which can be machined directly with modern production equipment. from a sheet metal or a pipe blank, faster and cheaper than it is possible to cast and process cast items in, for example, brass.
At the same time, there is a great desire to be able to completely avoid having to perform welding processes on a valve, as such processes require the respective items to be technically tightened at least once and that the welding process itself must be performed, which of course is expensive for the product. .
It is further a desire to be able to make a quick and simple assembly of both valve seat and valve body while at the same time achieving a high quality and safe and unambiguous placement of these parts in relation to the valve body and to each other.
The object of the invention
SUMMARY OF THE INVENTION It is an object of the invention to provide a solution to the above problem in which a valve is manufactured with a valve body and with at least one valve seat which can be easily and effortlessly mounted and fixed together with the valve body, where a minimum number of cutting and cutting work processes are performed beforehand. for mounting a valve seat and valve body.
Description of the Invention
As mentioned initially, the invention relates to a valve for regulating a fluid, the valve comprising a valve body, having a central portion and having two connecting ends, said connecting ends extending away from the central portion, and thus indicating a flow direction for said fluid, wherein a valve body is arranged inside the central portion, comprising a at least partially spherical surface for abutment against a corresponding valve seat, the valve body comprising at least one shut-off portion and a flow-through portion.
The new feature of a valve according to the invention is that said valve seat is arranged in the valve body and in resilient abutment against said valve body, wherein the valve seat comprises a resilient structural part, the spring actuation of said resilient structural part acting in a direction which is essentially parallel to the flow direction of the valve, and wherein the resilient structural member comprises at least one annular flange portion, said annular flange portion being arranged for direct or indirect abutment against the valve body.
Thus, the resilient structural member exerts a resilient pressure between the valve body and the valve body, whereby a seal between the valve body and valve seat is obtained and where it is also possible to obtain a seal between valve housing and valve seat, depending on the construction design. It is precisely the resilient effect of the valve seat or of its resilient structural member that allows a valve seat to absorb tolerances within a relatively large area, thereby providing greater security for the intended effect of the valve. This is achieved by the fact that it is an annular flange portion which at least partially exerts a spring pressure against the valve body. Because it is a resilient flange that interacts with the valve body, the abutment pressure and thus the friction between the valve seat and the valve body can be more easily kept at a necessary and at a relatively low level. With the known solutions with valve seats constituted by solid elastomeric elements mounted in the valve body, it is necessary to ensure and maintain a relatively large pressure between the valve seat and the valve body, since it is the inherent elasticity of the elastomeric material that takes up tolerances and ensures sufficient system pressure between the respective parts. A pressure typically having a size that causes a relatively large friction between valve seat and valve body. The flange portion thus has the advantage that it is not a compressed elastic solid item, but rather a flange portion is resilient, the effect of which is on a protruding annular flange portion - on a type of cantilever , upon which the packing element itself in the form of an elastomer blank may be arranged.
A valve according to the invention may comprise a valve housing with a valve body and with one valve seat arranged in a recess or recess in the valve housing and in abutment against the valve body. The valve body may be a more or less traditional spherical valve body, but it may also be a valve body comprising only a portion of a spherical shell, and thus comprising at least one spherical sectional area of the valve body locking member corresponding to the valve seat shape on the side which faces the valve body. By designing the resilient portion of the valve body as a flange portion extending more or less radially with respect to the valve body or to the passage through the flow portion of the valve body, a suitable abutment pressure is obtained against the valve body and thus a suitable but modest friction. The valve can be provided with only one inset valve seat for abutment against one side of a valve body. In a variant of a valve according to the invention, the valve may comprise two oppositely directed resilient valve seats. Thus, one valve seat may be arranged on each side of, for example, a spherical valve body in a classic ball valve. In such a case, the two valve seats will each exert a resilient force on the valve body, which will assist in positioning the valve body itself in a kind of equilibrium position where the influence of the two valve seats is uniform.
A valve according to the invention may be arranged such that the said valve seat (s) comprise a fixing member for mechanically fixing the valve seat in a valve housing, the fixing member comprising means for installation in a recess or the like in a valve housing. Such a solution can advantageously be used in larger valves with a flow opening of 50, 100, 200 millimeters or even larger, but also in smaller valves. By arranging the valve seat with a so-called fixing part, which may be, for example, a cylindrical part with a radially outwardly extending flange part, which constitutes either the flange part which is to be directly or indirectly abutting the valve body or a flange part between the cylindrical part and just that flange part, which must be directly or indirectly against the valve body, it is possible to place the valve seat in a dedicated track, in a recess or in a fit in the valve housing, where, for example, a gasket may also be located. Such a gasket may be arranged between partly the cylindrical fixing member and a more or less radial flange member on the valve seat and partly on the valve body itself. An example of this will be described below with reference to a figure.
Advantageously, a valve according to the invention may be arranged so that the resilient valve seat (s) comprise a fixing member for mechanically fixing the valve seat in a valve housing, the fixing member comprising means, for example a flange part, where these means are fixed in a valve housing by plastic deformation. of said valve body and / or by plastic deformation of said means. A preferred method for this is that said valve housing is made of a plastic deformable tubular member and that the valve seat is fixed therein by a deformation of said tubular member. Such deformation may comprise locking of a valve seat in a given position, the valve housing being deformed thereby securing the valve seat in the desired position, but also a deformation of both valve housing and said fixing member, whereby the same mechanical fixing or locking of the valve seat is achieved. In a variant of a valve according to the invention, the resilient valve seat (s) may comprise a fixing member for mechanically fixing the valve seat in a valve housing, the fixing member comprising means in the form of a flange part, the flange part being conical in a direction which is substantially parallel. with the flow direction, wherein said flange portion comprises an opening portion, said portion comprising an outside edge arranged for fixation internally of the valve body, said edge constituting or including a bar for engagement with the interior surface of the valve body, the outside diameter of the flange portion being greater than the inside diameter of the valve body in the area where the valve seat is located. Thus, when the valve body and one or two valve seats are mounted in the valve body, no further fixation is required, as the tapered flange portion cuts into the inner surface of the valve body, thus locking the valve seat in its final position. In principle, the same technique is used as is known from the so-called spring lock washers and which is also used in, for example, push-in fittings for compressed air and for other purposes. Here it is merely a matter of placing the resilient and locking element inside and not outside in relation to what is to be fixed. In a valve according to the invention, the valve seat may be made of resilient metal, for example stainless steel or another suitable alloy, wherein at least part of the valve seat, for example the resilient structural part in the form of an annular flange part, is coated with a relatively thin elastomeric surface. for example, PTFE or another suitable type of elastomer with an appropriate coefficient of friction and sealing effect. In such a solution, there is thus a direct connection between said annular flange portion and the valve body. The sealing effect can be expressed partly between the valve seat and the valve body, but also between the edge of the valve seat in engagement or abutment with the valve housing, whether the valve seat is fixed by a resilient lock or by deformation of valve housing and / or valve seat. In a variant of a valve according to the invention, the valve seat may be made of resilient metal, for example stainless steel or another suitable alloy, wherein at least part of the valve seat, for example the resilient structural part in the form of an annular flange part, comprises a bearing surface for a elastomeric gasket, for example, a ring of PTFE or another suitable type of elastomer with an appropriate coefficient of friction and sealing effect. With such a variant, the annular flange portion may be provided with a recess or recess in which an annular elastomeric gasket is arranged and thus causes the flange portion to abut indirectly against the valve body. Thus, the resilient structural part is one workpiece, while the packing part itself is constituted by another workpiece arranged on or in the annular flange part. Such a solution will be discussed below with reference to a figure.
The valve body may also be coated with a surface coating, for example an elastomer in the form of PTFE or another suitable elastomer, and both the valve body and valve seat may also have such a suitable coating, just as the valve body may have a suitable sealing or low friction coating which cooperates. with a gasket member arranged on or in an annular flange member.
Still another variant of a valve according to the invention may comprise that the valve seat comprises a tubular flange portion with an inner cross-sectional area, said tubular flange portion extending away from the valve body and towards a connecting end, said inner cross-sectional area substantially corresponding to the interior cross-sectional area of the through-hole in the valve body. The tubular flange portion extends in a particularly preferred embodiment from the flange portion abutting the valve body or from a recess on a flange portion for a valve seat gasket. The main purpose of this tubular flange portion is to guide the media for which the valve is intended. By having a tube-shaped flange, a more controlled flow of media is ensured in front and / or after a valve body, where otherwise there will typically be a gap in diameters. The tubular flange portion acts as a kind of skirt that guides the medium.
Regardless of the type of valve seats mentioned, these may advantageously be mounted with or in glue. The glue is typically applied inside the valve body and subsequently the valve seat is then mounted, but alternatively the glue can be applied to the valve seat prior to mounting it. The adhesive ensures that the valve seat is held in the desired position both during the further shaping of the valve and during the subsequent use of the valve, and partly that the adhesive ensures that there is a tightness between the valve body and the outer periphery of the valve, with minor scratches or irregularities in the interior. surface in the valve body and on the periphery of the valve seat is filled by the glue. In a preferred variant of a valve according to the invention, the valve body and at least one valve seat may be fixed in a valve housing, the valve housing having two connecting ends each with a diameter, at least one connecting end having a diameter substantially corresponding to the diameter of the valve body. either the valve body or on a valve seat. Hereby, the valve body and valve seat can be mounted inside the valve body via this connecting end and there is no need to perform the valve body in several parts in order to assemble these about the valve body and / or the valve seats.
The invention further relates to a method of producing a valve as mentioned above, wherein the valve is adapted to regulate a fluid, the valve comprising a valve housing, having a central part and having two connecting ends, said connecting ends extending away from the central part. and thus a flow direction for said fluid, wherein inside the central part is arranged a valve body comprising a at least partially spherical surface for abutment against a corresponding valve seat, wherein the valve body comprises at least one shut-off part and a flow-through part, where manufacture said valve at least comprising the following steps: - providing a valve body with a central portion; - a valve body is arranged in said central part; - at least one valve seat is arranged and fixed in said central part and in abutment against said valve body.
A method according to the invention can, in a variant, at least comprise the following additional steps: - fixation of said at least one valve seat occurs by deformation of the valve housing, where the deformation is carried out after the valve seat is arranged in the central part.
A further method according to the invention can at least comprise the following additional steps: - fixing said at least one valve seat by deformation of at least one flange part on said valve seat.
With the aforementioned methods, a valve according to the invention can be mounted and both the valve body and one or two valve seats can be fixed in a simple and quick way via one or both connection ends of the valve housing. Whether a valve seat is fixed by deformation of the valve body and possibly also by a fixing part on the valve seat or if the fixing is done by the valve seat exerting a spring force on the inner side of the valve body, a easy and fast mounting and fixing of the respective parts in relation to each other. Examples of what a valve according to the invention may look like are shown below.
With this method, the valve can be manufactured, for example, in untreated steel, in a series of continuous and automated working processes and before or after mounting, the production may be terminated with a surface treatment. Such a valve and method of producing a valve are extremely advantageous, as the process is simple and occurs in a natural order. However, in a preferred variant of the invention, the valve housing may advantageously be made in, for example, a carbon steel already provided with a zinc coating or other suitable coating. For example, a steel pipe may be used which is galvanized by a suitable type of galvanizing process. This gives the obvious advantage that the surface treatment is carried out prior to the valve body being machined to its final geometric shape, which results in a lower production cost of the finished product.
A valve comprising a valve housing according to the invention is typically designed such that said connection ends have an inner diameter substantially corresponding to the inner diameter of the valve body. Thus, it is a so-called full flow valve which can advantageously be used in many places where a more unobstructed flow is needed in the medium flowing through the valve. The connector ends of the valve body may be designed as required and may be provided with either male or female ends and may comprise all conceivable types of couplings for connecting connecting tubes or hoses. Including clutches of the press-fitting type and flanges for bolt assembly or for a suitable assembly.
Thin-walled materials are currently gaining ground in the industry and are increasingly being used for industrial solutions as well as for plumbing installations in residential construction. There are countless advantages to thin-walled pipes and fittings and the assembly methods are very simple, avoiding the time-consuming and costly work of thread cutting, welding or brazing.
A valve housing according to the invention may advantageously be made of a thin-walled material such as either untreated or surface treated carbon steel or stainless steel, the valve housing being formed by plastic deformation of said material, for example by hydroforming or by axial molding or by another suitable process. Exactly hydroforming and axial shaping have proven to be particularly suitable for the manufacture of a valve body, since such a process is both quick and inexpensive compared to the traditional manufacturing methods for valve housings typically made of sintered, cast or forged brass or other suitable material, which is subsequently machined and fitted with a valve insert. Furthermore, both hydroforming and axial forming are very precise shaping methods and a good tolerance can be obtained.

Detailed Description of the Invention In FIG. 1, a portion of a valve 1 is shown in cross-section, where a valve housing 2 comprises a central part 3 and two connecting ends 4. In the central part 3 a valve body 5 is provided with a through opening 6. The valve body 5 is connected to a valve stem 7 and supported and fixed by two valve seats 8. In the variant shown, the valve seats 8 are fixed in that the two connecting ends 4 are deformed to a smaller internal cross-section, whereby the valve seats 8 are locked in their position with respect to both the valve body 5 and the valve housing 2. As can be seen in the figure, the valve seat 8 has a flange portion 9 abutting the valve body 5 and a flange portion 10 abutting the inner side of the valve body 2. The flange portion 9 abutting the valve body 5 exerts a slight influence on the valve body 5, thereby providing a seal between these parts. By the valve seat 8 being designed and mounted as shown here, the pressure exerted as a fluid by closed valve 1 may also act on the back of the flange portion 9, thereby pressing the flange portion 9 against the valve body 5, resulting in an even more optimal seal between the two. topics 5, 9.
FIG. 2 also shows a valve housing 2, with a central part 3, with connecting ends 4 and with a valve body 5 arranged between two valve seats 8. The difference between this figure and FIG. 1, the valve seats 8 are fixed only by the flange portion 10 being pressed against the inner side of the valve housing 2, thereby locking according to the same principle as in the various known push-in fittings, where engaging as a barbs with - in this case - the inner surface of the valve body. The valve seat 8 is seen here as a two-layer structure, which can be partly a rigid steel layer and partly a less rigid surface coating, for example PTFE or another suitable surface coating with the right material properties for the present task.
FIG. 2 can also be considered in another way in which the figure shows a method step in which the valve body 5 and the two valve seats 8 are arranged in a valve housing 2 immediately before it is deformed as seen in fig. 1. Both of the two considerations are relevant and a valve 1 according to the invention can be manufactured in either way as required or desired. Whether it is the cutting action of the flange 10 which acts as the final fixation or as a temporary fixation prior to the deformation of the connection transmitters 4, the valve body 5 and the valve seats 8 can easily and without significant difficulty be placed in the desired position, where a sufficient system pressure is established between the valve body 5 and the valve seat 8. Common to the solutions seen in fig. 1 and 2 is that both the valve body and valve seats and associated gaskets can be mounted in the central part 3 of the valve housing through one or both of said connecting ends 4. Thus, the valve housing 2 is not composed of several parts. In FIG. 3 is a cross-sectional view of a valve seat 8 with tapered fixing portion corresponding to flange portion 10 and flange portion 9 arranged for abutment against valve body 5. In addition, the previously mentioned two-layer construction is seen, where one layer 11 is steel, while the other Layer 12 is a surface coating, for example PTFE or other suitable material. The steel layer 11 is intended to provide stiffness and resilient properties to the valve seat 8, while the surface coating 12 is intended to seal between the valve body 5 and valve seat 8 while at the same time exerting so low / low friction between the two parts 5, 8 that the valve 1 can operated between a closed and an open position. However, the layer 11, which is made of steel here, may also be made of other materials, including metal, plastic, fiber-reinforced composite or other suitable materials. The same applies to the layer 12 of surface coating material which can be completely omitted or alternatively made of any suitable material. The thickness of the layer 11 and the layer 12 can be selected as needed so that the required elasticity, friction or other desired parameter is obtained. In FIG. 4 also shows a cross section of a valve seat 8, which is here formed / deformed as shown in FIG. 1. This shaping may have occurred prior to mounting in the valve body 2, but may also occur during deformation of the valve body 2 only after placement of the valve body 5 and valve seats 8. The coating 12 may furthermore be on only the portion of the valve seat 8 which contacts the valve body 8. valve body 5, which generally corresponds to the flange portion 9.
FIG. 5 also shows a cross-section of a valve seat 8 with a partial surface coating 12, thus leaving part of the flange part 10 free without coating 12. This allows better contact between the edge 13 of the flange part 10 and the inner side of the valve housing 2, which is particularly advantageous in the case that the valve seats are mounted and fixed by the edge 13 cutting into the interior surface of the valve housing. The shape of the layer 12 can be varied and applied as required and in the example shown it is seen that on the flange portion 9, which is intended to face the valve body 5, a coating 12 is arranged in a convex shape.
FIG. 6 shows a sectional view of a valve 1 with only one valve seat 8, the valve body 5 being a part of a ball shell, which is not a closed ball-shaped valve body 5 as shown in FIG. 1 and in FIG. 2. The valve body 5 is mounted here with a valve spindle 7, but also with a control spindle 14, as seen at the top of the figure. The valve seat 8 is also designed in a different way, being fixed with abutment in a recess 15 in the valve housing 2. The recess further comprises an additional recess 16 for a gasket 17. The variant of a valve seat seen in FIG. 6, is provided with a cylindrical flange portion 18 which is longitudinally disposed of the inner surface of the valve housing 2 and which is connected to a radial flange 19 which together with the cylindrical flange portion 18 forms a gasket surface for abutting said gasket 17. From the radial flange 19 extends a tapered inwardly flange 20 which in turn communicates with a tapered outward flange portion 9 which is adapted to abut the valve body. Thus, in this variant of a valve 1 according to the invention, tolerances can be accommodated and / or exerted a resilient effect on the valve body 25 from both the flange portion 9, but also from the tapered inward flange 20, which together constitute a kind of resilient bellows.
FIG. 7 shows a valve seat 8 as seen and discussed in the description of FIG. 6th
FIG. 8 is a sectional view of yet another variant of a valve 1 with spring-locked valve seat 8, showing a part of a valve housing 2, with a central part 3, with a connecting end 4 and with a valve body 5 in abutment with a valve seat 8. As also shown in FIG. 2, the valve seat 8 is here fixed only by the flange portion 10 being pressed against the inner side of the valve housing 2, thereby locking according to the same principle as in the various known push-in fittings. In the shown variant of a valve 1, the connecting end 4, after mounting the valve body 5 and valve seat 8, is deformed to a smaller diameter than the central part 3 itself, without the flange part 10 towards the inner side of the valve housing 2 being deformed. However, it will also be possible to fix a valve seat 8, as shown in this figure, in the same way as shown in FIG. 1, where a flange portion 10 is deformed.
However, there is the more significant difference between the valve seat 8 in this figure and the one shown in fig. 2, that a recess 21 is formed in the valve seat 8, on the flange portion 9, in which a valve seat gasket 22 is arranged. In this variant of a valve 1, both the valve seat gasket 22 and the flange member 9 act resiliently to the valve body 5, but the valve seat gasket 22 can in principle be very rigid with respect to the flange member 9, so that it is the flange member 9 which provides the necessary and desired spring force against the valve body 5.
The valve seat gasket 22 may be mounted with, for example, glue to the flange portion 9, it may be loose or it may be fixed by some form of clamping in the structural part of the valve seat 8. For example, the flange portion 9 may be formed with a recess which cooperates with a corresponding projections on the valve seat gasket 22 such that the two parts 8, 22 are fixed completely or partially in relation to each other.
FIG. 9 still shows a sectional drawing of a variant of a valve 1 with spring-locked valve seat 8. In principle, this is a solution which is largely identical to the solution as shown in FIG. 8. There is, however, the difference that the valve seat 8 here comprises a cylindrical tubular flange portion 24 extending from the recess 21 of the flange portion 9 and towards the connection end 4. This cylindrical tubular flange portion 24 causes a significantly more uniform flow. of the medium to which the valve 1 is used, the medium being, so to speak, guided the direct path and not flowing uncontrolled in the area before and after valve body 6 and valve seats 8. In fig. 9, glue 25 is also seen which ensures tightness between valve housing 3 and valve seat 8.
The invention is not limited to the embodiments described above, nor to the embodiments shown in the drawings, but can be supplemented and modified in any way according to the invention as described and defined in the claims.
