Abstract
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 couplerand a second couplerare provided with a vacuum sectionbetween an inner pipe sectionand an outer pipe section, and are provided with two valvesin series. A remaining-fluid-transferring mechanism is provided such that, after second valvesB provided further inward enter a closed-valve state during emergency detachment, residual fluid that remains closer to the first valvesA than the second valvesB is transferred into the inner pipes sectionsprovided further inward of the second valvesB. Once emergency detachment is in a completed state, heat insulation sectionsare formed in the space between the first valveA and the second valveB in each of the first couplerand the second coupler, and heat insulation performance is improved by the heat insulation sectionsand the vacuum sections
