Description

Technical Field

[0001] The utility model relates to the technical field of rubber sheets, and more specifically, to a combined valve rubber sheet with a long service life. Background Technique

[0002] The valve rubber sheet, also known as the valve rubber seal, is a sealing component installed on a valve. In the oil fracturing industry, the valve rubber sheet is applied to the valve assembly of the high-pressure plunger pump of a fracturing truck. This assembly consists of a valve body, a valve seat, and a valve rubber sheet. As the main working machine of the fracturing truck, the high-pressure plunger pump has high standards for the performance of the valve rubber sheet, including the need to resist high pressure, corrosion, and wear. During operation, the valve rubber sheet not only has to withstand high pressure and chemical corrosion but also endure the erosion of mud and sand while ensuring good sealing performance.

[0003] For example, Chinese Patent No. CN221374446U discloses an enhanced valve rubber sheet. By setting a special-shaped ring, the support strength at the lower sharp corner can be enhanced, and the pressure-bearing capacity at the lower sharp corner can be improved. The performance of the special-shaped ring and the rubber gasket complement each other, effectively preventing damage to the lower sharp corner of the rubber gasket due to closing and extrusion.

[0004] Although the performance of the special-shaped ring and the rubber gasket complement each other, when the rubber gasket is damaged, attention still needs to be paid to the performance of the rubber gasket under extreme working conditions. If the rubber gasket is damaged during use, it needs to be replaced in time to ensure overall sealing performance and operation safety, otherwise, the overall service life will be reduced.

[0005] Regarding the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0006] Regarding the problems in the related technology, the present utility model proposes a combined valve rubber sheet with a long service life to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To this end, the specific technical solution adopted by the present utility model is as follows:

[0008] A combined valve rubber sheet with a long service life includes a valve rubber sheet body. A sealing outer ring is arranged on the outer side of the valve rubber sheet body. Both ends of the sealing outer ring are connected to a first wear-resistant ring and a second wear-resistant ring through a plurality of clamping components, and the first wear-resistant ring and the second wear-resistant ring have the same structure; a splitting opening is provided on the valve rubber sheet body. A hollow-out groove matching the valve rubber sheet body is provided on one side of the splitting opening. A limiting hole is provided at the top of the hollow-out groove, and a limiting post is arranged inside the limiting hole; a clamping convex block matching the limiting post is arranged on one side of the hollow-out groove. A limiting groove matching the limiting post is provided at the top of the clamping convex block. A fillet is arranged on the outer side of the end of the first wear-resistant ring.

[0009] Furthermore, in order to reduce the direct wear on the outside of the valve rubber body under the combined action of the sealing outer ring, the clamping component, and wear-resistant ring 1 and wear-resistant ring 2, and by setting rounded corners on the outer sides of wear-resistant ring 1 and wear-resistant ring 2, the friction generated between wear-resistant ring 1 and wear-resistant ring 2 and the outside world is reduced, thereby increasing the service life of wear-resistant ring 1 and wear-resistant ring 2. At the same time, under the action of the clamping component, wear-resistant ring 1, wear-resistant ring 2 and the sealing outer ring are connected to protect the valve rubber body from direct wear, thereby increasing the service life of the valve rubber body and ensuring the use efficiency of the valve rubber body. The surface of the rubber sealing outer ring is evenly provided with a number of installation grooves that cooperate with the clamping component, and the surface of the installation groove is provided with a rubber soft ring that cooperates with the clamping component.

[0010] Furthermore, in order to reduce the direct wear on the outside of the valve rubber body under the combined action of the sealing outer ring, the clamping component, and wear-resistant ring 1 and wear-resistant ring 2, and by setting rounded corners on the outer sides of wear-resistant ring 1 and wear-resistant ring 2, the friction generated between wear-resistant ring 1 and wear-resistant ring 2 and the outside world is reduced, thereby increasing the service life of wear-resistant ring 1 and wear-resistant ring 2. At the same time, under the action of the clamping component, wear-resistant ring 1, wear-resistant ring 2 and the sealing outer ring are connected to protect the valve rubber body from direct wear, thereby increasing the service life of the valve rubber body and ensuring the use efficiency of the valve rubber body. The clamping component includes a connecting column provided at the top of wear-resistant ring 2, and the outer side of the connecting column cooperates with the rubber soft ring. A clamping block that cooperates with the installation groove is provided at the top of the connecting column, and the shape of the clamping block is spherical.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. Under the combined action of the sealing outer ring, the clamping component, and wear-resistant ring 1 and wear-resistant ring 2, the present utility model uses wear-resistant ring 1 and wear-resistant ring 2 to reduce the direct wear on the outside of the valve rubber body, and by setting rounded corners on the outer sides of wear-resistant ring 1 and wear-resistant ring 2, the friction generated between wear-resistant ring 1 and wear-resistant ring 2 and the outside world is reduced, thereby increasing the service life of wear-resistant ring 1 and wear-resistant ring 2.

As Figures 1 - 5As shown in the figure, the combined valve rubber sheet with a long service life according to an embodiment of the present invention includes a valve rubber sheet body 1. A sealing outer ring 2 is arranged on the outer side of the valve rubber sheet body 1. Both ends of the sealing outer ring 2 are connected to a wear-resistant ring 1 4 and a wear-resistant ring 2 5 through a plurality of clamping components 3, and the structures of the wear-resistant ring 1 4 and the wear-resistant ring 2 5 are the same; a splitting opening 6 is formed on the valve rubber sheet body 1. A hollowing groove 7 matching with the valve rubber sheet body 1 is formed on one side of the splitting opening 6. A limiting hole 8 is formed at the top of the hollowing groove 7, and a limiting post 9 is arranged inside the limiting hole 8; a clamping convex block 10 matching with the limiting post 9 is arranged on one side of the hollowing groove 7. A limiting groove 11 matching with the limiting post 9 is formed at the top of the clamping convex block 10. A fillet 12 is arranged on the outer side of the end of the wear-resistant ring 1 4.

[0025] With the aid of the above technical solution, in the present invention, under the combined action of the sealing outer ring 2, the clamping components 3, the wear-resistant ring 1 4 and the wear-resistant ring 2 5, the wear-resistant ring 1 4 and the wear-resistant ring 2 5 are used to reduce the direct wear on the outside of the valve rubber sheet body 1, and through the arrangement of the fillets 12 on the outer sides of the wear-resistant ring 1 4 and the wear-resistant ring 2 5, the friction generated between the wear-resistant ring 1 4 and the wear-resistant ring 2 5 and the outside world is reduced, thereby increasing the service life of the wear-resistant ring 1 4 and the wear-resistant ring 2 5. At the same time, under the action of the clamping components 3, the wear-resistant ring 1 4, the wear-resistant ring 2 5 and the sealing outer ring 2 are connected, thereby protecting the valve rubber sheet body 1 from direct wear, thereby increasing the service life of the valve rubber sheet body 1 and ensuring the use efficiency of the valve rubber sheet body 1; under the combined action of the hollowing groove 7, the limiting hole 8, the limiting post 9, the clamping convex block 10 and the limiting groove 11, the stability of the connection at the oil seal splitting opening 6 is ensured, and the valve rubber sheet body 1 can be quickly installed and disassembled, improving the working efficiency of the valve rubber sheet body 1 during the installation and disassembly process.

[0026] In one embodiment, for the above-mentioned sealing outer ring 2, a plurality of installation grooves 201 matching with the clamping components 3 are evenly formed on the surface of the sealing outer ring 2. A rubber soft ring 202 matching with the clamping components 3 is formed on the surface of the installation groove 201. Thus, under the combined action of the sealing outer ring 2, the clamping components 3, the wear-resistant ring 1 4 and the wear-resistant ring 2 5, the wear-resistant ring 1 4 and the wear-resistant ring 2 5 are used to reduce the direct wear on the outside of the valve rubber sheet body 1, and through the arrangement of the fillets 12 on the outer sides of the wear-resistant ring 1 4 and the wear-resistant ring 2 5, the friction generated between the wear-resistant ring 1 4 and the wear-resistant ring 2 5 and the outside world is reduced, thereby increasing the service life of the wear-resistant ring 1 4 and the wear-resistant ring 2 5. At the same time, under the action of the clamping components 3, the wear-resistant ring 1 4, the wear-resistant ring 2 5 and the sealing outer ring 2 are connected, thereby protecting the valve rubber sheet body 1 from direct wear, thereby increasing the service life of the valve rubber sheet body 1 and ensuring the use efficiency of the valve rubber sheet body 1.

And through the rounded corners 12 arranged on the outer sides of the first wear-resistant ring 4 and the second wear-resistant ring 5, the friction generated between the first wear-resistant ring 4 and the second wear-resistant ring 5 and the outside world is reduced, thereby increasing the service life of the first wear-resistant ring 4 and the second wear-resistant ring 5. At the same time, under the action of the clamping component 3, the first wear-resistant ring 4, the second wear-resistant ring 5 and the sealing outer ring 2 are connected, so as to protect the valve rubber body 1 from direct wear, thereby improving the service life of the valve rubber body 1 and ensuring the use efficiency of the valve rubber body 1.

[0028] The installation principle of the clamping component 3, the first wear-resistant ring 4, the second wear-resistant ring 5 and the sealing outer ring 2 is as follows: The present utility model adopts a plurality of clamping components 3. At the same time, installation grooves 201 and rubber soft rings 202 equal in number to the clamping components 3 are arranged on the surface of the sealing outer ring 2. During the installation process, the clamping block 302 of the clamping component 3 squeezes the rubber soft ring 202, and the rubber soft ring 202 enters into the interior of the installation groove 201, and thus is fixed inside the installation groove 201 by the rubber soft ring 202.

[0030] During actual application, first, the limit post 9 passes through the limit hole 8 and is matched with the limit groove 11 of the clamping convex block 10, thus completing the installation of the valve rubber body 1. Then, the sealing outer ring 2 and the valve rubber body 1 are set as an integral structure. A number of clamping components 3 are arranged on the surfaces of the first wear-resistant ring 4 and the second wear-resistant ring 5. The first wear-resistant ring 4 and the second wear-resistant ring 5 are installed on the top and bottom of the rubber sealing outer ring 2 by using the clamping components 3, and the installation of the entire valve rubber body 1 is realized, reducing the direct wear on the valve rubber body 1 and increasing the service life of the valve rubber body 1.

[0031] The installation principle of the clamping component 3, the first wear-resistant ring 4, the second wear-resistant ring 5 and the sealing outer ring 2 is as shown above.

At the same time, under the action of the clamping assembly 3, the first wear-resistant ring 4, the second wear-resistant ring 5 and the sealing outer ring 2 are connected, so as to protect the valve rubber body 1 from being directly worn, thereby improving the service life of the valve rubber body 1 and ensuring the use efficiency of the valve rubber body 1; under the combined action of the hollow groove 7, the limiting hole 8, the limiting post 9, the clamping convex block 10 and the limiting groove 11, the stability of the connection at the oil seal split 6 is ensured, so that the valve rubber body 1 can be quickly installed and disassembled, and the working efficiency of the valve rubber body 1 during installation and disassembly is improved.
