The valve consists of king valve 2, check valve 5 and needle valve 1 It is composed of ball valve 3 and pressure gauge 4. The slow closing check valve has the check function of opening and closing speed regulation. After the valve is installed, it can effectively control the water pump to automatically adjust to the best opening and closing speed when starting and stopping. It is applicable to the direct water supply and drainage system of open-pit enterprises and high-rise buildings by pumps to reduce the occurrence of water hammer and water hammer, so as to achieve the effect of safe shutdown.
