1座位安全阀的铅封和锁的选择

Reply #22019-02-17

安全阀设置的前后阀门，之前包括一些标准规定都是讲要标注CSC和CSo，最近看到一份流程图，上面全部标准的是LC和lo。这两种到底如何选择呢，区别到底在哪里

安全阀前后都要锁开或铅封，要不安全阀有什么作用

就是文字上的的区别吧，我觉得不用扣字眼

最好是铅封！被人误操作了，铅封断开，能一眼发现；如果用锁，是可以防止别人误操作，但遇到紧急时刻需要动作阀门，还要开锁浪费时间，万一钥匙找不到，那可能就要出大问题了。

考虑到实际操作的便捷性和可靠性工程上一般使用铅封

csc和cso是铅封，类似于家里面电表及水表那个铅封，lc和lo就是锁，需要钥匙开关。 lc
