摘要

介绍了一种具有慢速开启、快速关闭和缓冲功能

以及可通过调整不同的弹簧预紧力来实现不同快速动作时间要求的集成型、无需外供油源的汽轮机组用快速关断阀

该快速关断阀快关可靠

结构紧凑

无安装方向限制。

Abstract

A rapid shut-off valve

which is an integrated type

needing no oil source from outside

and being used for steam turbine units

has been presented

the said rapid shut-off valve boasting functions of slow speed to open

rapid shut-off

and buffer effect

as well as can realize the requirement of different rapid action time through adjustment of spring's different pretightening force.Comparing with other rapid shut-off values

the said spring rapid shut-off valve can be securely rapid shut-off

having compact structure

and without limitation for installing orientation.
