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 system includes a first shut-off valve unit which is land-based; and a second shut-off valve unit which is provided for a marine vessel and separably connected to the first shut-off valve unit, and the first shut-off valve unit is provided with a reservoir container which receives liquid air generated in the first shut-off valve unit and dropped, in a state in which the second shut-off valve unit is separated from the first shut-off valve unit, and the system includes a container support mechanism which is capable of retaining the reservoir container at a retracted position in a state in which the first and second shut-off valve units are connected to each other, the container support mechanism being configured to automatically shift the reservoir container to a reserving position, in a state in which the first and second shut-off valve units are separated from each other.
