Novel check valve structure

Technical Field

The utility model relates to a check valve technical field among the automobile brake system especially relates to a novel check valve structure.

Background

The function of the check valve is to allow the medium to flow in one direction only, but to prevent the flow in the opposite direction. Typically such valves are self-actuating, with the flap opening under the pressure of a fluid flowing in one direction; when the fluid flows in the opposite direction, the valve clack is acted on the valve seat by the fluid pressure and the self weight of the valve clack, thereby cutting off the flow. The check valve on the hydraulic control valve body of the automobile brake system generally comprises a valve body, a valve core and a spring, liquid can only be allowed to circulate in one direction during working, the condition that the valve core is poor in sealing and the spring does not return completely after long-time use results in that the sealing effect of the check valve is reduced when the automobile is braked emergently, and the braking effect of the automobile is influenced.
