The check valve is used in the piping system, its main function is to prevent the backflow of the medium, prevent the pump and its driving motor from reversing, as well as the release of the medium in the container.
Check valves can also be used to feed pipes where the pressure may rise to exceed the pressure of the main system. Check valve according to the different material, can be applied to a variety of media pipeline.
The check valve is installed on the pipeline, which becomes one of the fluid components of the complete pipeline. The opening and closing process of the valve disc is affected by the transient flow state of the system in which it is located. In turn, the closing characteristics of the disc have an effect on the fluid flow state.
