一起阀门事故导致的系统停车

Shutdown of system due to a faulty valve

因减压阀门运作过快,导致氢气调节阀跟不上氯气调节阀的动作,氯氢压差大于上限值,引发系统连锁跳停。针对事故原因,提出排查电器仪表设备、加强巡检和培训的事故防范措施。

Pressure reducing valve operated so quickly that the action of hydrogen regulating valve could not follow the action of difference exceeded upper limit, chlorine regulating valve, and thus which triggered off interlock shutdown prevention measures were proposed, including investigating electric strengthening inspection and training. the chlorine-hydrogen pressure of the whole system.
