Application of swing check valve

Swing check valve, also known as one-way valve or check valve, is used to prevent the medium in the pipeline. The valve whose opening and closing parts open or close automatically by medium flow and force to prevent medium is called check valve. The check valve is an automatic valve, which is mainly used on the pipeline with one-way flow of medium. The medium is only allowed to flow in one direction to prevent accidents. This type of valve shall be installed horizontally in the pipeline。

DBV according to the swing check valve adopts the 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 used at the middle flange, there are no external leakage points as a whole, so as to eliminate the possibility of valve leakage. The connection between rocker arm and disc of swing check valve adopts spherical connection structure, so that the disc has a certain degree of freedom within 360 degrees and appropriate micro position compensation.
