核电站用主蒸汽隔离阀性能分析

Performance Analysis of Main Steam Isolation Valve for Nuclear Power Plant

介绍了主蒸汽隔离阀的技术发展历程,分析了目前核电站采用的闸阀式气液联动主蒸汽隔离阀和蒸汽自驱动式主蒸汽隔离阀及平衡球型主蒸汽隔离阀的结构特性,提供了主蒸汽隔离阀的研究方向。

The technical development of main steam isolation valve is introduced in this article. The structures of classical Edward Equi-wedge MSIV with gas/hydraulic actuator; of steam-driven MSIV; as well as of equi-ball designed MSIV are all presented. This article is aimed at giving some advice for the MSIV research.
