Swing Check Valves Description
Valve is an important mechanical device in the pipeline, through the valve opening and closing, adjustment, control equipment and pipeline medium pressure, flow and direction. Valve classification is a lot of check valves refers to the media itself rely on the flow and automatically open and close the valve flap, allowing the media to flow in a one-way valve to protect pipeline machinery and equipment from water hammer damage plays an important role. Check valve work process water hammer transient impact pressure ΔH may be higher than the normal working pressure of several times, the performance of the system stability and reliability of the work has a great impact on the stability of multiple pumps in parallel with the application of high-pressure piping systems, check valve water hammer problem is more prominent, in order to prevent water hammer in the pipeline hidden danger, the design of the valve to use some of the new structure, new materials, to ensure that the valve work characteristics, while the water hammer The impact force of water hammer is minimized.
