Device and method for effectively controlling closing of water hammer prevention valve

The invention discloses a device and a method for effectively controlling closing of a water hammer prevention valve, and relates to the technical field of long-distance pipeline conveying. The devicecomprises a water conveying pipeline 1, wherein a manual ball valve 1 and the water hammer prevention valve are sequentially arranged on the water conveying pipeline in the water flow direction, a water conveying pipeline 2 is connected to the water conveying pipeline 1 in a branched T mode, and a manual ball valve 2 and a manual ball valve 3 are sequentially arranged on the water conveying pipeline 2. According to the device and the method for effectively controlling closing of the water hammer prevention valve, the original control mode of the water hammer prevention valve is changed, so that the water hammer prevention valve has a reasonable and rapid closing function, the working time of overhauling and maintenance is shortened, water resources are saved, a certain effect on preventing corrosion of the pipeli
