Muffler check valve refers to the valve that automatically opens and closes the disc depending on the flow of the medium itself to prevent the medium from flowing back. It is also called check valve, one-way valve, muffler check valve, reverse valve, and back pressure valve. The check valve is a kind of automatic valve, its main function is to prevent the back flow of the medium, prevent the pump and the drive motor from reversing, and the discharge of the container medium. Check valves can also be used to supply pipelines where the pressure of the auxiliary system may rise above the system pressure. Check valves can be divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).


The function of the silencing check valve is to prevent the flow in the opposite direction and only allow the medium to flow

 in one direction. Usually this kind of valve works automatically. Under the action of fluid pressure flowing in one direction, 

the valve flap opens; when the fluid flows in the opposite direction, the fluid pressure and the self-coincidence of the valve 

flap act on the valve seat, thereby cutting off the flow. It is not suitable for medium containing solid particles and high viscosity.
