Description

technical field [0001] The invention relates to the technical field of drainage and pipelines, in particular to a water hammer elimination device. Background technique [0002] When a pump stop water hammer accident occurs in the pump station, it will cause "running of water" and water stoppage, and in severe cases, the pump room will be flooded, so that the factory will be forced to stop production, damage the infrastructure, and some equipment will be damaged by the water hammer. The damage caused casualties. The water hammer effect refers to a serious water shock caused by the water flow hitting the pipeline when the feed water pump starts and stops. Because the inner wall of the water pipe is smooth and the water flows freely, when the valve is opened Sudden shutdown or stop of the water supply pump, the water flow will generate a pressure on the valve and the pipe wall, mainly the valve or the pump. Because the pipe wall is smooth, the subsequent water flow will quickly...
