Abstract: The safe operation of the device about interlock valve device,and if the valve position to malfunction,the control valve is unable to track the actual valve position. Operator can’t through the remote monitoring to observe valve is in what state,easy to cause abnormal shutdown. This paper provides for the screening of field and circuit method and the corrective actions,eventually eliminate the problems,maintain the normal production of the safety device.
