摘要： To provide an emergency detachment mechanism for a fluid handling device that has exceptional heat insulation performance and enables liquid hydrogen or another very-low-temperature fluid to be handled. An emergency detachment mechanism for a fluid handling device provided with a pair of couplers 1, wherein each of the pair of couplers 1 has a coupler body part 5 including an internal tube part 2 in which a fluid passes through an interior and which opens at a distal end side, an external tube part 3 which forms a vacuum layer 9 with the internal tube part 2 and which opens at a distal end side, and a connecting flange part 4 that closes off a space between the internal tube part 2 and the external tube part 3, a wall thickness of the connecting flange part 4 being less than a wall thickness of the external tube part 3.

摘要： An object is to provide an emergency detachment device of a fluid handling device, the emergency detachment device having exceptional heat insulation performance and making it possible to handle extremely-low-temperature fluids such as liquid hydrogen. A first coupler 2 and a second coupler 3 are provided with a vacuum section 10 between an inner pipe section 5 and an outer pipe section 6, and are provided with two valves 1 in series. A remaining-fluid-transferring mechanism is provided such that, after second valves 1B provided further inward enter a closed-valve state during emergency detachment, residual fluid that remains closer to the first valves 1A than the second valves 1B is transferred into the inner pipes sections 5 provided further inward of the second valves 1B. Once emergency detachment is in a completed state, heat insulation sections 9 are formed in the space between the first valve 1A and the second valve 1B in each of the first coupler 2 and the second coupler 3, and heat insulation performance is improved by the heat insulation sections 9 and the vacuum sections 10.

摘要： An emergency release mechanism is applied to fluid loading equipment for transporting fluid, and includes: a pair of pipe portions having a vacuum double structure in each of which a flow path for transporting the fluid is formed, the pair of pipe portions being arranged with opening ends abutting against each other; a coupling member capable of coupling the pair of pipe portions to each other and being removed therefrom; and a pair of shutoff valves configured to shut off the flow path in the pipe portions. The pair of pipe portions respectively include valve seats formed in the flow path. The shutoff valves respectively include valve bodies configured to seat on the respective valve seats to close the flow path, and linear motion drive devices configured to move the respective valve bodies along the flow path to cause the valve bodies to seat on the respective valve seats.

摘要： Each of a pair of couplers includes: a vacuum double-pipe structure main part; a valve seat forming an opening through which a fluid flows; and a valve body in the main part. The valve body is configured such that, when separating the couplers, in each coupler, the body is brought into contact with the seat by a spring to close the opening, and when coupling the couplers, the body of each coupler is pressed by the body of the other coupler to move away from the seat and open the opening. The valve body includes: a holding member holding a sealing material sealing between the body and the seat when the body is in contact with the seat; a resin block covering a distal end surface of the holding member; and a metal operating member accommodating the block and protruding from the holding member to pass through the opening.
