Structural principle of swing check valve（1）

The swing check valve adopts an internal rocker arm swing structure, and all the opening and closing parts of the valve are installed inside the valve body, without penetrating the valve body. Except for the sealing gasket and ring used in the middle flange part, there are no external leakage points overall, eliminating the possibility of valve leakage. The connection between the swing arm and the valve disc of the swing check valve adopts a spherical connection structure, allowing the valve disc to have a certain degree of freedom within a 360 degree range and appropriate micro position compensation.Suitable for cleaning media, not suitable for media containing solid particles and high viscosity.
