Background

The check valve is a valve which automatically opens and closes a valve flap by the flow of a medium and is used for preventing the medium from flowing backwards, and is also called a check valve, a one-way valve, a reverse flow valve and a back pressure valve. The check valve is an automatic valve and mainly used for preventing medium from flowing backwards, preventing the pump and a driving motor from reversing and discharging container medium. Check valves may also be used in lines that provide makeup to auxiliary systems where the pressure may rise above the system pressure, and may be largely divided into swing check valves (rotating about the center of gravity) and lift check valves (moving along an axis) that function to allow media flow in only one direction and to prevent 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 reverse direction, the valve clack is combined by the fluid pressure and the self weight of the valve clack and acts on the valve seat, so that the flow is cut off;
