<p>PROBLEM TO BE SOLVED: To provide an automatic valve device inspection system, when an emergency situation occurs during an inspection, minimizing a delay time in dealing with a fire by shortening a transfer time from stopping a remote-control inspection to a water spray standby state.SOLUTION: When an inspection recovery water discharge instruction section 98 instructs a pilot valve 30 to open and stops a remote-control inspection in an inspection state of the test water discharge for passing a pressure water from a secondary side to a water discharge side of an automatic valve, on the basis of a detection of a fire signal, the inspection recovery water discharge instruction section retains the stopped inspection state as a water discharge standby state, and does not restore to a steady monitoring state for closing the automatic valve. When detecting a water discharge signal in the water discharge standby state, with the automatic valve opened, the inspection recovery water discharge instruction section instructs an inspection valve 40 functioned as an inspection valve and a test water discharge valve 42 to change to the steady positions, fully opens a test gate valve by the drive of a hydraulic actuator, supplies the pressure water from the secondary side of the automatic valve to a water spray head, and discharges water without any need of a recovery time of the automatic valve to the steady monitoring state.</p> |
