FO、FC我见过，但是这个什么意思呢？ FI = Fail to Intact FR = Fail to Remain 请大神指教，多谢了

看下HG/T 20505-2014 过程测量与控制仪表的功能标志及图形符号

没有一致的东西啊，这俩我查了都是保持的意思啊

Reply #42018-05-23

FI 是任意位置，FR是复位吗？

Reply #52018-05-24

都是故障保持的意思，具体需要看回路图。在信号回路和气源回路方面，有区别。

Reply #62018-05-24

FI应该是故障保持，FR也是故障保持吧

Reply #72018-05-25

我查的英语也是这个意思，感觉不太对。FL是什么呢？

Reply #82018-05-25

FL应该是故障锁定吧。fail lock

Reply #92018-05-25

一般不单独标识“FL”, 而是“FLC”或 “FLO”，表示故障锁定及趋向。

阀门故障形式 FI指的是流量不足，而FR指的是泄漏。后面应该还带有O或者C才对。
