The slow-closing check valve is an intelligent valve installed at the outlet of the water pump in the water supply system of high-rise buildings and other water supply systems to prevent medium backflow, water hammer and water hammer. This valve has three functions: electric valve, check valve and water hammer eliminator, which can effectively improve the safety and reliability of the water supply system. It also integrates the technical principles of slow opening, quick closing, and slow closing to eliminate water hammer to prevent the occurrence of water hammer when the pump starts and when the pump stops.
