摘　　要：研究了阀调节V S(Valve Stroking)的理论和计算方法 ,并将阀调节应用于泵系统的水锤防护中 ,对事故停泵过渡过程进行了计算机模拟 .计算结果表明 ,方法较好地解决了长管道泵系统中的气液两相瞬变流的控制问题 ,消除了水锤危害 ,具有构思新颖、实用易行等优点 。The calculation method of Valve-Stroking was studied and applied to waterhammer in pumping system with long pipe. The computer simulation of the transition process of unexpected pump-stop was made. It is proved that the method is effective to control gas-liquid transient in pumping system. It is practical and has important significance to reduce the cost of project and management.
