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.
