在我国给排水工程中,常用的泵后阀门一般是由止回阀、闸阀共同承担的。对于高层建筑、长距离输水泵站,还要装设水锤消除装置。这些装置不仅消耗了大量生铁材料和增加了泵房占用面积,而且给管理、操作等均带来不便。 In China’s water supply and drainage project, commonly used after-pump valves are generally shared by check valves and gate valves. For high-rise buildings and long-distance water pumping stations, water hammer elimination devices must also be installed. These devices not only consume a large amount of pig iron material and increase the footprint of the pump room, but also cause inconvenience to management, operation, and the like.
