Claims

[Scope of utility model registration request]

In an emergency disconnection device for a fluid cargo handling line that disconnects one and the other couplings provided in the middle of the fluid cargo handling line in an emergency to interrupt the flow of the fluid cargo handling line, the one and the other couplings include: The valve head is inserted so as to be slidable along the axial direction of the coupling, and when both couplings are detached, the valve head is pressed against the connection opening edge of each coupling by the biasing means, and the flow path of each coupling is opened. At the same time, the protrusion of the spacer rods provided protruding from each of the valve heads is minimized, and when both couplings are joined, the spacer rods contact each other, thereby causing the biasing means to move in opposite directions. One and the other slide valves are pushed against a biasing force to open a flow path between the two couplings, and when the two couplings are joined, the slide strokes of the two slide valves are restricted. The slide valves are provided with stopper rings on one side and the other side for holding the flow paths of both couplings in an open position. The valve head is molded in such a shape that a uniform cross-section of the flow path is formed between the valve head and each slide valve, and a sealing pad that is removably attached to the entire circumference is attached to the portion of the valve head that is pressed against the connection opening edge. An emergency disconnection device for a fluid cargo handling line, characterized in that an emergency disconnection device is attached to the fluid cargo handling line.
