摘要
主要介绍抽汽逆止阀的开闭控制原理,对原水控系统出现的故障原因进行分析,并结合实际提出改造方案,将抽汽逆止阀开启的控制动力由水控系统改为气控系统,消除了故障。
The open and close principal of the exhaust check valve is mainlyintroduced. The causes of faults in the original water control system were analyzed andmodification program was put forward based on real condition. The control power for openingthe check valve was changed to pneumatic control system from water control system, whichhas eliminated such failures.
