摘　　要：向家坝水电站技术供水系统采用单机单元自流减压供水方式,为避免长时间运行使冷却设备换热器管网内部淤塞,该水电站左岸厂房机组技术供水系统采用由四个水力控制阀组成的正、反向供水阀门组,以定期对管网进行正、反向冲洗,保证供水系统正常的冷却效果。A gravity-flow pressure-reduced water supply mode is adopted in the technical water supply system of Xiangjiaba Hydropower Station. However,long time operation of the system could cause the internal clogging of the heat exchange pipes of the cooling device. Thus,a double-direction water supply valve group with four hydraulic control valves are adopted in the technical water supply system in the left bank power plant,which could be used to flush the pipes forward and reversely. With this strategy,the cooling performance of the water supply system is guaranteed.
