Description

Pneumatic valve seat Technical Field The utility model belongs to the technical field of air pressure valve seats, and particularly relates to an air pressure valve seat. Background The air pressure valve is a device for controlling fluid flow driven by compressed air, a valve core and a valve seat are key components in the valve, the valve core is a movable component in the valve, and the valve core changes the flow passage sectional area by moving in the valve seat so as to regulate the flow rate and the pressure of fluid. The valve seat is a gasket arranged in the valve body and mainly used for forming a sealing surface by being matched with the valve core so as to prevent fluid leakage. However, in actual use, solid particles may be contained in the fluid and wear of the internal material of the pneumatic valve may occur over time to produce debris. In the process of opening and closing the low-flow-rate or pneumatic valve, the solid particles can stay on the valve seat sealing surface to obstruct or interfere the tight contact between the valve seat sealing surface and the valve core surface, so that the sealing effect of the valve can be reduced, gas leakage is caused, and the normal operation of equipment is influenced. It can also lead to wear and corrosion of the valve seat sealing surfaces, resulting in more frequent maintenance and even replacement of damaged valve seats by the user, increasing maintenance costs. Accordingly, in view of the above-described problems, it is necessary to provide a pneumatic valve seat.
