弹簧微启封闭式安全阀指依靠弹簧的弹性压力而将阀的瓣膜或柱塞等密封件闭锁,一旦当压力容器的压力异常后产生的高压将克服安全阀的弹簧压力,所以闭锁装置被顶开,形成了一个泄压通道,将高压泄放掉。
弹簧微启封闭式安全阀区别于一般的全启式安全阀，其泄压后可自动关闭,无需人手动复位,A41H弹簧微启封闭式安全阀适用于工作温度≤300℃的石油气、空气、水等介质的设备或管路上。A41Y-P/R不锈钢安全阀适用于工作温度≤200℃有腐蚀性介质的设备或管路上,作为超压保护装置。连接法兰标准按JB/T……94/系列1。
Scope of application（SANJING VALVE）
A41H type are used for the equipment and pipeline of the petroleum gas air water etc medium what are working temperature are less than ≤300℃ A41Y-P/R type are used for the equipment and pipeline of the quality with corrode medium what the wirking temperatrue are less than 200℃ Take for extra pressure devices Flange connecting dimentsions of comply with Standard series first of JB/T...94
