小浪底西沟水电站调压系统优化设计研究

小浪底西沟水电站输水管道0+000—0+838.71桩号段由小浪底水利枢纽原灌溉洞改建而成。根据电站规模及布置条件,对单纯设置调压阀和"调压井+调压阀"两个方案进行了引水系统水力过渡过程计算和分析,确定调压系统采用"调压井+调压阀"方案布置。调压井布置在0+750.00桩号处,对调压井进行了支护和结构设计,解决了调压系统设计的难题。

Optimization of Pressure Regulator System of Xiaolangdi Xigou Hydropower Station

Xiaolangdi Xigou Hydropower pipeline 0+000-0+838.71 section had been converted from the irrigation tunnels of Xiaolangdi Water Control Project.According to the power plant size and the layout conditions,it was compared with the combined action of surge shaft and horizontal relief valve,and water system hydraulic transition processes of two options were calculated and analyzed.It is determined to use the program layout of "combined action of shaft and horizontal relief valve ".Surge shaft has been arranged in the place of 0+750.00,which was supported and designed for structure to solve the regulator problem of system design.
