在黄壁庄水库灵正渠电站设计中,实行工人、干部、技术人员相结合,经过调查研究,合理地采用了安全阀——爆破膜装置代替调压塔设计。这次措施为国家节省投资三万多元,约占电站总投资的10%。安全阀——爆破膜装置代替调压塔作调节保证措施的基本原理是:当机组正常运行时,引水管内压力正常,安全阀呈关闭状态。当甩负荷急速关机时,引水管内发生水锤,压力上升超过安全阀整定值时,水压力使安全阀自动开启,泄放一定流量,限制了水锤压力上升。同
In the design of Lingzhengqu Hydropower Station in Huangbizhuang Reservoir, the combination of workers, cadres and technicians was adopted. After investigation and study, the safety valve - blasting membrane device was adopted instead of the pressure regulating tower design. This measure saves more than 30,000 yuan for the state, accounting for about 10% of the total investment of the power station. Safety valve - Burst membrane device instead of regulating tower to ensure the adjustment of the basic principles is: When the normal operation of the unit, the water pipe pressure is normal, the safety valve was closed. When the rejection load quickly shut down, the occurrence of water hammer within the water pipe, the pressure rises over the safety valve setting, the water pressure to automatically open the safety valve, a certain flow of discharge, limiting the water hammer pressure rise. with
