Production Introduction
The swing check valve adopts a built-in rocker swing structure. All the opening and closing parts of the valve are installed inside the valve body and do not penetrate the valve body. Except for the sealing gasket and sealing ring at the middle flange, the whole There is no leakage point, preventing the possibility of valve leakage. The swing arm of the swing check valve adopts a spherical connection structure at the connection between the rocker arm and the valve clack, so that the valve clack has a certain degree of freedom within the range of 360 degrees, and there is an appropriate trace position compensation. Suitable for clean medium, not suitable for medium containing solid particles and high viscosity.
