Description

Technical Field

[0001] The utility model relates to the technical field of air intake valves, in particular to a valve seat cushion for an air intake valve. Background Art

[0002] An air intake valve is an accessory that maintains stable pressure within a pipe without requiring a ventilation duct. It's typically installed at the top of each horizontal branch pipe and on risers several floors apart. The air intake valve operates by opening the valve disc when negative pressure develops within the drainage pipe, allowing air to enter. When positive pressure develops, the disc closes, preventing harmful gases from entering the room. The air intake valve seat is a crucial component, primarily responsible for maintaining the valve's temperature. During installation, a gasket is typically placed underneath the seat to aid in installation.

[0003] However, the existing intake valve seat gasket is usually a metal component. Since the surface of the seat gasket is relatively smooth, after connection, as the intake valve works for a long time, the valve seat gasket is easy to loosen. Therefore, a rubber gasket is usually placed on the surface of the seat gasket to increase friction and prevent the valve seat gasket from loosening. During long-term use, the gasket is easy to separate from the seat gasket, resulting in poor sealing performance of the seat gasket. After the rubber gasket is separated from the seat gasket, the uneven force on its various parts causes the rubber gasket to be easily damaged, requiring frequent replacement, which is inconvenient to use. Utility Model Content

[0004] The purpose of this application is to provide an intake valve seat pad to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: an intake valve seat gasket, comprising a gasket, wherein the top outer wall and the bottom outer wall of the gasket are both provided with anti-slip pads, the anti-slip pads are adapted to the gasket, the thickness of the anti-slip pads is less than the thickness of the gasket, the anti-slip pads are made of nitrile rubber, the gasket and the anti-slip pads are both in a circular shape, the outer wall of the gasket is provided with a sealing ring, the sealing rings are respectively adapted to the gasket and the anti-slip pad, the thickness of the sealing ring is the same as the sum of the thickness of the gasket and the anti-slip pad, a connecting component is provided between the gasket and the anti-slip pad, and the connecting component is respectively adapted to the gasket and the anti-slip pad.

[0006] Preferably, the working inner diameter of the sealing ring is the same as the outer diameter of the gasket and the anti-slip pad, the sealing ring is made of elastic rubber, and the initial inner diameter of the sealing ring is smaller than the outer diameter of the gasket and the anti-slip pad.

[0007] Preferably, the connecting component includes fixing holes opened on the top and bottom outer walls of the gasket, an adhesive pad is installed on the inner wall of the fixing hole, the anti-slip pad is provided with a connecting hole on the outer wall close to the gasket side, an adhesive patch is provided on the inner wall of the connecting hole, and the adhesive patch is adapted to the adhesive pad.

[0008] Preferably, threaded holes are provided on the outer wall of the gasket and the outer wall of the anti-slip pad, and the threaded holes are arranged in a circular shape at equal distances.

[0009] Preferably, both the top outer wall and the bottom outer wall of the gasket are provided with limit blocks, the limit blocks are located between the adhesive pads, and the height of the limit blocks is less than the thickness of the anti-slip pad.

[0010] Preferably, the anti-slip pad has a limiting hole on its outer wall close to the gasket, the limiting hole is matched with the limiting block, the number of the limiting holes is the same as the number of the limiting blocks, and the depth of the limiting hole is less than the thickness of the anti-slip pad.

[0011] In summary, the technical effects and advantages of the utility model are:

[0012] 1. In the utility model, when the gasket is used, the gasket and the valve seat are connected by fixing bolts through the threaded holes. The anti-slip pad increases friction, making the fixing bolts more securely installed. After the suction valve has been working for a long time, the valve seat and the gasket are not easy to loosen and separate, which is beneficial to extending the service life of the gasket. The sealing ring seals the connection between the valve seat and the gasket to improve air tightness and prevent gas leakage when the suction valve is working. Compared with traditional devices, the sealing ring and the anti-slip pad enhance the air tightness and friction of the gasket, and are tightly connected to the gasket. They are not easy to separate without external interference, making the gasket not easy to loosen after long-term use and more durable. At the same time, the sealing ring and the anti-slip pad can be manually separated from the gasket for easy replacement and use.

[0013] 2. In the present invention, when the anti-slip pad is connected to the gasket, the adhesive sticker and the adhesive pad are aligned, and the anti-slip pad and the gasket are connected by bonding the two together. The anti-slip pad and the gasket will not separate in the absence of external interference, preventing the anti-slip pad and the gasket from separating during use and affecting the normal operation of the gasket. The limiting hole is connected to the limiting block to improve the stability of the anti-slip pad. During the operation of the gasket, the anti-slip pad will not be displaced by gas impact.
