水电站多用途调压阀应用

Application of Multi-purpose Pressure Regulating Valve in Hydropower Station

通过一具体工程,系统地介绍了在没有条件设置调压井的低水头小型水电站,采用电磁换向阀控制的多用途调压阀,用于替代调压井以及兼做灌溉阀和安全泄压阀的应用,并附有相关的选择计算,可为类似电站调压阀的应用提供参考。

Based on a specific project, this paper systematically introduces a multi-purpose Pressure Regulating Valve （PRV） controlled by solenoid directional control valve to be adopted for replacing of surge shaft and also adopted as irrigation valve and safe relief valve in a low-head small-scale hydropower station without conditional to set surge shaft. The paper also carries out the relevant selection calculation. It can provide areference for the application of PRV in a similar power station.
