【摘要】：正1研究背景在扬水泵站输水管道系统中,止回阀承担着防止水泵倒转和水锤防护的重要作用,作为水泵的保护装置,是水泵管路系统最基本的防护设备。本文就不同管道断面的扬水管道止回阀关闭特征和时间条件设定,与对应的水泵运转及管道压力变化条件进行分析,针对在目前管道建设项目中多采用二阶段控制关闭型止回阀问题,通过工程案例探讨泵站止回阀的关闭特征和时间条件选择与泵站安全防护经济性的关系。2止回阀的关闭特征和时间条件
[Abstract]:Background in the water pipeline system of pumping station, check valve plays an important role in preventing water pump reverse and water hammer protection. As the protection device of water pump, it is the most basic protective equipment of pump pipeline system. In this paper, the closing characteristics and time conditions of check valves for different pipe sections are analyzed, and the corresponding conditions of pump operation and pipeline pressure change are analyzed. In order to solve the problem of adopting two-stage control closed check valve in the current pipeline construction project, Discussion on the relationship between the closing characteristics and time condition of check Valve in pumping Station and the economy of Safety Protection in pumping Station through the Project case .2 the closing characteristic and time condition of check Valve
