流体の排出部材とを設ける。
Means for Solving the Problems A pressurized nonflammable gas supply member and a pipe fluid discharge member are provided between the two valves.

作用 緊急時には2個のバルブを閉鎖し、2個のバルブの間に
残っている管路内流体を不燃性ガスで迅速に追出し、し
かる後にバルブの中間部を切離す。
In the event of an emergency, the two valves are closed, the fluid remaining in the pipeline between the two valves is quickly expelled with non-flammable gas, and then the middle part of the valve is disconnected.

9 is an actuator for driving an inlet valve; 9 is an actuator for driving an outlet valve; and 10 is an actuator for driving an outlet valve. In such a device, the inlet valve 7 is supplied with pressurized nonflammable gas such as nitrogen gas. Valve 1 is activated automatically or by a signal from the operator as soon as an emergency occurs.
, 2 are closed by an actuator 3 for driving the valve 1 and a link mechanism 4. The closed position of valve 1.2 is detected by a limit switch (not shown) whose signal causes valve 7.9 to be opened by actuator 8.10. At this time, pressurized non-flammable gas is constantly supplied to the line on the inlet valve 7 side, and when the inlet valve 7 is opened, the non-flammable gas flows between the valves 1 and 2 and flows into the outlet valve 7. 97 to drain the liquid or gas between valve 1.2. At the same time as the discharge is completed, valve 7.8 is closed and disconnection device 5 is activated to disconnect.

As a result, the liquid or gas between the valves 1 and 20 will not flow out to the outside (it can be recovered).The discharged liquid or gas will be transferred to the drain or tank line on the land or ship side via piping connected to the outlet valve 9. or to a tank permanently installed on the loading arm or bridge.
