Swing check valve infomation: Check valve swing check valve
Check valve can be called as upstream valve, non-return valve, backpressure valve and one-way valve. Kind of this valve is opening and closing by the power of the medium going through the pipe. It is belong to an automatic valve. Check valve is using for piping system. Its main function is to prevent the backflow medium, prevent the reverse of pump and drive, prevent the mediumin in the container to discharge. It can also be used the pressure of the system pressure may rise over the auxiliary system supply piping.
Swing check valve can be different according to the material, and suitable for various kinds of medium.
Swing check valves are installed in the pipeline, which become one fluid part of the complete pipeline. The disc of the valve will be effected by the flowing state. Conversely, the closing character of swing check valve will also effect on the fluid flowing state. Th working feature of the check valve is large loading, and small frequency of opening and closing. The period of the using will be longer and no need to request the moving parts to move, But once again "switch" requirement, it must to be moving flexibly. This requirements is more critical than common mechanical moving.
