大梁水库是引黄工程北干线上一个以城市供水及工业用水为主的水利工程，该水库主要用于对总干线上总流量进行调节，使得总干线在停运期间能够持续对下游用户供水，使得水资源得到充分合理的利用。主要研究水库放水系统，通过运用数值模拟与理论计算相结合的方法，对放水系统过渡过程进行计算和分析。结果表明：高压调流阀开启与关闭可采用100 s线性规律，管道系统的最低压力发生在最大泄流流量时阀门关闭工况，位于高压调流阀出口。

Daliang Reservoir is a hydraulic project on the North Line of Yellow River diversion project ,which is applied to urban wa‐ter supply and industrial water .The reservoir is mainly used to adjust the total flow on North Line ,which can continue to supply water with the downstream users and fully rational use of water resources .To discuss the drainage system transition process of Daliang Reservoir ,numerical simulation combined with theoretical analysis methods has been applied in the research to calculate and analyze the transition process .It show s that the opening and closing of high pressure flow-adjustable valve can adjust linear law of 100 s ,and low pressure of piping systems occurs at the maximum discharge flow conditions w hen the valve is close ,it is located in the high-pressure regulating valve outlet .
