を切離す。Conventional technology Figure 2 shows the concept of a conventional emergency release device? show. In the same figure, 01 and 02 are valves, 03 is a disconnection device, and 04 and 05 are hydraulic actuators for driving the valves.In an emergency, the actuators are operated 04.05Y, and after closing the valve 01.02', the disconnection device 03 is activated. Disconnect the conduit.
発明が解決しようとする問題点
管路の切離し時は、バルブとバルブの間に封入された液
もしくは気体が外部へ流出するため非常に危険である。Problems to be Solved by the Invention When a pipe line is disconnected, it is extremely dangerous because the liquid or gas sealed between the valves will leak out.
問題点を解決するための手段
２個のバルブの間に加圧不燃性ガスの供給部材と管路内
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.

is a disconnection device, 6 is a check valve, 7 is an inlet valve, 8
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.

クへ戻すことが出来る。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.
発明の効果
緊急時に管路を切離す前に、２個のバルブの間に残って
いる流体？不燃性ガスで置換するので、管路を切離す際
にバルブ間の流体が外部に流出せず、安全な切離しを行
うことができる。Effects of the Invention: Fluid remaining between two valves before disconnecting the pipe in an emergency? Since the replacement is performed with nonflammable gas, the fluid between the valves does not leak out when the pipe is disconnected, allowing safe disconnection.
