Technical Field

The utility model belongs to the field of valves, and relates to a check valve, in particular to a high-performance buffering silencing check valve.

Background

The check valve functions to prevent flow in the opposite direction and to allow flow in only one direction. Typically such valves are automatically operated, with the valve flap opening under the pressure of fluid flowing in one direction; when fluid flows in the opposite direction, the self-weight of the valve clack acts on the valve seat by the pressure of the fluid and the self-weight of the valve clack, thereby cutting off the flow. It is not suitable for fluids containing solid particles and having a relatively high viscosity.

The valve clack of the check valve widely applied in the market at present is under the action of spring force, self-generated gravity of the valve clack and back flow fluid force to accelerate the linear motion to close the valve, so that the impact force between the valve clack sealing surface and the valve body sealing surface of the traditional check valve is relatively large, the noise is relatively large, and the sealing pair formed by the valve clack sealing surface and the valve body sealing surface is easily damaged by the impact of large force, so that the check sealing performance of the traditional check valve is invalid, and the service life is shortened.
