核电再热阀组结构设计与分析

Nuclear Power Reheat Dual Valve Units

介绍了核电再热阀组的应用工况、运行参数及其使用要求,分析了阀门的结构特点、运行过程及驱动方式。核电再热阀组是安装在从汽水分离器(MSR)出口至中压缸或低压缸入口之间的再热管道上的阀门,其主要作用是参与汽轮机负荷调节及在系统紧急情况下快速关闭以防止汽轮机超速。目前,该类型阀门已应用到工程项目中。

This paper briefly describes the application conditions and uses of the nuclear reheat valve group,and briefly introduces the structural characteristics and functions of the valve.The nuclear reheat valve group is a valve installed on a reheat pipe from the outlet of the steam separator(MSR) to the inlet of the intermediate or low pressure cylinder,Its main role is two,One is involved in steam turbine load regulation,and the other is to quickly shut down in an emergency to prevent turbine overspeed.This type of valve is currently used in engineering projects.
