Fall short height reduces the inertia time is also relatively reduced speed, and can prevent the formation of destructive or reduce water hammer water hammer.Quick closing and silencing check valve and silencing check valve is to rely on the flow of the medium itself automatically open and close the valve, backflow valve to prevent the media, also known as check valve, check valve, silent check valve reflux valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure.
