产品简介
A49H、GA49H型主安全阀主要用于电站锅炉、压力容器、减温减压装置上使用，防止压力超过允许Z高压力值，保证设备安全运行。

详情介绍

A49H、GA49H型主安全阀
产品型号：A49H-4
 
GA49H型主安全阀说明：

　　主要用于电站锅炉、压力容器、减温减压装置上使用，防止压力超过允许zui高压力值，保证设备安全运行。

GA49H型主安全阀结构简述：

1、当介质压力升高到整定压力时，冲量安全阀打开，介质从脉冲管进入主安全阀的活塞室，推动活塞下降，使阀门自动打开，当冲量阀关闭时，阀瓣又自动关闭。
2、密封面用钴基铬镍不锈钢堆焊而成，阀瓣经热处理，提高了耐磨性和抗冲蚀性。

GA49H型主安全阀安装说明：

1、阀门必须垂直安装在设备的zui高位置。
2、主安全阀紧固在支座上，支座承受主安全阀排汽时产生的反座力。
3、排汽管应有专门吊架，排汽管重量不得加在主安全阀上，主安全阀与排汽管之间的连接法兰应消除任何的附加预应力。
4、排汽管的zui低点应考虑疏水，以免排汽时产生水击。
