Document Type and Number:
Japanese Patent JP2022183097
Kind Code:
A
Abstract:
To protect an exterior of a stationary tank or an exterior of a movable semitrailer from overpressure in a space between walls.SOLUTION: A cryogenic container 1 comprises an inner wall 2 defining a storage volume, and an outer wall 3 having a space 4 between vacuum insulation walls, and disposed around the inner wall. A pressure-control valve 5 configured so as to discharge excessive pressure in the space between the walls is disposed on the outer wall. The pressure-control valve can move between a first position and a second position thereof, and is guided in a vertical direction via a guide system located inside an opening. A cap is configured to be moved toward the second position by overpressure greater than a threshold determined in the space between the walls, and to be returned toward the first position by gravity when the overpressure greater than the determined threshold is stopped.SELECTED DRAWING: Figure 1
