摘要
在中小型引水式水电站中,为达工程安全和经济的要求,常需设置调压阀来作为调节保证措施。文中针对目前现状,结合西藏某水利水电站工程实例,对有压引水系统在设置有调压阀和无调压阀时,两种情况的大波动稳定性进行了计算、分析。论证了用调压阀代替调压井的可行性,为类似工程设计提供参考。
In small and medium-sized diversion hydropower stations,to meet the safety and economic requirements of the project,it is often necessary to set up a pressure regulating valve as a guarantee measure.In view of the present situation and combining with the engineering example,the large fluctuation stability of the pressurized water diversion system with and without pressure regulating valve is calculated and analyzed.The feasibility of replacing pressure regulating well with pressure regulating valve is demonstrated,which provides reference for similar engineering design.
