产品详情
简单介绍:
弹簧微启封闭式**阀A41H-16C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型适用于工作温度≤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。
详情介绍:
**阀是一种由进口静压开启的自动泄压防护装置,它是压力容器*为重要的**附件之一,它的功能是:当容器内压力超过某一定值时,依靠介质自身的压力自动开启阀门,迅速排出一定数量的介质。当容器内的压力降到允许值时,阀又自动关闭,使容器内压力始终低于允许压力的上限,自动防止因超压而可能出现的事故,所以**阀又被称为压力容器的*终保护装置。
**阀常见故障及原因
【**阀漏气】(1)阀芯与阀座接触面不严密;(2)阀芯与阀座接触面有脏物;(3)阀杆偏斜。
【**阀到规定压力时不开启】(1)阀芯与阀座粘住,可做手动排气试验排除;(2)弹簧式**阀的弹簧调整压力过大,应重新调整;(3)杠杆式**阀的重锤向后移动,应将重锤移到原来定压的位置上,用限动螺丝紧固。
【**阀不规定压力时开启】(1)弹簧式**阀的弹簧调整压力不够、弹簧失效或弹力不足,应重调或重换**阀;(2)杠杆式**阀重锤向前移动,应将重锤移到原来定压的位置上,用限动螺丝紧固。
