Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel valve plates, in particular to a stainless steel valve plate structure. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Among them, the valve plate is one of the important components that plays the opening and closing function.

[0003] At present, when using stainless steel valve plates, there is a lack of auxiliary anti-wear mechanisms. Usually, after long-term use, stainless steel valve plates are prone to wear at the edges and corners due to the rigid friction with the inner wall of the valve body, which not only affects the sealing of the valve plate, but also accelerates the service life of the valve. Therefore, a stainless steel valve plate structure is proposed to increase the auxiliary anti-wear mechanism and form a protective structure on the periphery of the valve plate, which can not only slow down the wear rate of the valve plate, but also help to extend the service life of the valve, thereby improving the use effect. Summary of the invention

[0004] In view of the problems in the prior art, the utility model provides a stainless steel valve plate structure, so as to add an auxiliary anti-wear mechanism and form a protective structure on the periphery of the valve plate, thereby improving the use effect.

[0006] The valve plate assembly comprises a valve plate, and a valve stem is connected to the valve plate via bolts. Both sides of the valve plate are sleeved with elastic washers, and an extended edge is arranged on the inner side of the elastic washers.

[0007] By adopting the above technical solution, it is convenient to add an anti-wear mechanism, improve the sealing performance of the valve plate, and extend the service life.

[0008] Specifically, the sheath assembly includes a sheath, and the valve plate is connected to the sheath by welding, and a sealing gasket is provided on the outer shell of the sheath.

[0009] By adopting the above technical solution, it is convenient to add a sealing protection mechanism and improve the service quality of the valve stem.

[0010] Specifically, bosses corresponding to the elastic gaskets are provided on both sides of the valve plate, and snap-in slots corresponding to the extended edges are provided on the surfaces of the bosses.

[0011] By adopting the above technical solution, it is convenient to form a slot structure for installing the elastic gasket.

[0012] Specifically, surfaces on both sides of the extended edge are provided with inclined protrusions.

[0013] By adopting the above technical solution, the stability of the installation of the extended edge can be improved.

[0014] Specifically, an annular groove corresponding to the sealing gasket is formed on the surface of the sheath.

[0015] By adopting the technical solution, it is convenient for the sealing gasket to be sleeved with the sheath.

[0016] Specifically, buffer pads are connected on both sides of the valve plate by gluing.

[0017] By adopting the above technical solution, the impact of the fluid on the valve plate can be alleviated.

[0018] Beneficial effects of the utility model:

[0019] The stainless steel valve plate structure described in the utility model can add an auxiliary anti-wear mechanism on the periphery of the valve plate by means of the valve plate, elastic gasket and extended edge, which can not only reduce the rigid friction wear rate of the valve plate corners, but also improve the sealing of the valve plate, thereby improving the use effect and quality of the valve plate.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] In order to facilitate the addition of auxiliary anti-wear mechanisms, a protective structure is formed on the periphery of the valve plate to improve the use effect, such as Figure 1-3 As shown, a stainless steel valve plate structure described in the utility model comprises a valve plate assembly 1, a valve stem 2 and a sheath assembly 3, wherein the valve plate assembly 1 is provided with the valve stem 2 at the top, and the sheath assembly 3 is provided at the top of the valve plate assembly 1 and located at the periphery of the valve stem 2;

[0029] The valve plate assembly 1 includes a valve plate 101 , and the valve stem 2 is connected to the valve plate 101 by bolts. Both sides of the valve plate 101 are sleeved with elastic washers 102 , and the inner side of the elastic washers 102 is provided with extended edges 103 .

[0030] When in use, the valve plate 101, the elastic gasket 102 and the extended edge 103 can provide a buffer and anti-wear structure, thereby improving the sealing performance of the valve plate 101 and slowing down the loss rate, thereby improving the quality and effect of the valve.

[0031] The valve plate 101 is made of stainless steel.

[0032] In order to improve the use quality of the valve stem 2, for example, Figure 1 , Figure 4 As shown, the utility model further includes that the sheath assembly 3 includes a sheath 301 , and the valve plate 101 is connected to the sheath 301 by welding, and a sealing gasket 303 is provided on the outer periphery of the sheath 301 .

[0033] When in use, the sheath 301 and the sealing gasket 303 can be used to avoid contact with the fluid in the valve, thereby improving the use quality of the valve stem 2.

[0034] For example, Figure 2 As shown, the utility model further includes that bosses 104 corresponding to the elastic gasket 102 are provided on both sides of the valve plate 101 , and a bayonet 105 corresponding to the extended edge 103 is opened on the surface of the boss 104 .

[0035] When in use, the boss 104 and the bayonet 105 facilitate forming a clamping structure, thereby improving the stability of the installation of the elastic gasket 102 .

[0036] For example, Figure 3 As shown, the utility model also includes that surfaces on both sides of the extended edge 103 are provided with inclined protrusions 106 .

[0037] When in use, both sides of the bayonet 105 are provided with slots corresponding to the inclined protrusions 106 , so that the inclined protrusions 106 can be easily inserted into the corresponding slots of the bayonet 105 , thereby further increasing the stability of the extended edge 103 .

[0038] For example, Figure 4 As shown, the utility model also includes that the surface of the sheath 301 is provided with an annular groove 302 corresponding to the sealing gasket 303 .

[0039] When in use, the annular groove 302 facilitates installation of the sealing gasket 303 .

[0040] For example, Figure 1 As shown, the utility model also includes that both sides of the valve plate 101 are connected with buffer pads 4 by gluing.

[0041] When in use, the buffer pad 4 can be used to mitigate the impact of the fluid in the valve on the valve plate 101 .

[0042] When the utility model is in use, firstly, when the valve stem 2 drives the valve plate 101 to rotate, the elastic contact friction between the elastic gasket 102 and the inner wall of the valve body can reduce the loss caused by the traditional rigid friction, which not only improves the working sealing performance of the valve plate 101, but also prolongs the service life. Moreover, by connecting the extended edge 103, the inclined protrusion 106 and the card slot of the bayonet 105, the valve plate 101 can be prevented from falling off during the working process, and the connection is more tightly fitted.

[0043] During the use of the valve stem 2, the sheath 301, the annular groove 302 and the sealing gasket 303 can increase the sealing performance of the valve stem 2, making it less likely to be corroded by contact with the fluid in the valve. The structure is simple, the cost is low, and the use is more stable and reliable.
