摘要： An object is to propose a fluid handling device for liquid hydrogen that prevents evaporation of liquid hydrogen, and moreover affords excellent heat insulation without liquefying oxygen in the vicinity. In a fluid handling device for liquid hydrogen, piping sections (1) have a heat insulation structure, a swivel joint section (2) is configured with helium gas sealed into a boundary relative-rotation section (6) between an outer ring section (3) and an inner ring section (4) with a bearing section (5) interposed, and moreover, between an outside-air-contacting wall section (7) that is in contact with the outside air and a liquid-hydrogen-contacting wall section (8) that is in contact with liquid hydrogen, a vacuum section (9) extends in the axial direction and moreover a heat-conducting extended path section (10) is provided with one end connected to the outside-air-contacting wall section (7) and the other end connected to the liquid-hydrogen-contacting wall section (8), extending the heat conduction distance between the outside-air-contacting wall section (7) and the liquid-hydrogen-contacting wall section (8), and reducing heat conductivity between the outside-air-contacting wall section (7) and the liquid-hydrogen-contacting wall section (8).

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.
