摘要
论述了超临界火电机组给水系统再循环用调节阀多级减压组件汽蚀损坏的原因,介绍了在调节阀后建立一段有效水柱压力可以减弱或避免调节阀减压组件受汽蚀损坏的方法。
This paper discusses the causes of the cavitation damage of the multi - stage decompression component for the water supply system control valve of the supercritical thermal power unit, introduces the method of setting up an effective water column pressure behind the control valve to reduce or avoid cavitation damage for decompression component of the control valve.
