Waterproof hammer silencer check valve its structural  structural characteristics only allow the medium to flow in one direction and prevent the direct of flow .Usually this valve is automatic work ,in the direction of the flow of fluid flows in the opposite direction the fluid pressure and the self -coincidence of the valve disc act on the valve seat ,thus cutting off the flow .It is not suitable for medium containing solid particles and high viscosity .

When the medium flows in the specified direction ,the valve disc is opened by the force of the medium , Medium countercurrent ,due to the weight of the valve disc and the valve disc by the reverse force of the medium ,so that the valve disc and the sealing surface of the valve seat closed the closed , to prevent the purpose of the medium countercurrent .
