EMERGENCY REMOVAL DEVICE FOR FLUID HANDLING DEVICE
Document Type and Number:
Japanese Patent JP2017020584
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an emergency removal device for fluid handling device showing a superior heat insulation property and enabling handling of cryogenic fluid such as liquid hydrogen and the like to be realized.SOLUTION: In this invention, a first coupler 2 and a second coupler 3 are configured to have vacuum segments 10 between inner pipes 5 and outer pipes 6 and there are provided two valves 1 arranged side-by-side. There is provided a residual fluid transferring mechanism operated in such a manner that under an emergency removal state, after each of the second valves 1B installed at a deep location is closed, residual fluid left in the first valves 1A rather than in the second valves 1B is transferred into the inner pipes 5 placed at the deep side of the second valves 1B. Under a state of completion of emergency removal, a heat insulation part 9 is formed among the first valves 1A and the second valves 1B of each of the first coupler 2 and the second coupler 3 and then heat insulation property is improved by the heat insulation part 9 and the vacuum segments 10.SELECTED DRAWING: Figure 2
