摘要： An emergency release mechanism is applied to fluid loading equipment for transporting fluid, and includes: a pair of pipe portions having a vacuum double structure in each of which a flow path for transporting the fluid is formed, the pair of pipe portions being arranged with opening ends abutting against each other; a coupling member capable of coupling the pair of pipe portions to each other and being removed therefrom; and a pair of shutoff valves configured to shut off the flow path in the pipe portions. The pair of pipe portions respectively include valve seats formed in the flow path. The shutoff valves respectively include valve bodies configured to seat on the respective valve seats to close the flow path, and linear motion drive devices configured to move the respective valve bodies along the flow path to cause the valve bodies to seat on the respective valve seats.

摘要： Vacuum-insulated double-wall piping for transporting a cryogenic fluid includes an inner pipe that includes a bellows part, and an outer pipe that is provided to the outer periphery of the inner pipe with a vacuum layer interposed therebetween, the vacuum-insulated double-wall piping having a straight pipe section and elbow sections. The vacuum-insulated double-wall piping is characterized in that the bellows part is provided to an inner-pipe straight pipe section positioned in the straight pipe section, protruding parts that protrude outward toward the outer pipe are provided to inner-pipe elbow sections positioned in the elbow sections, and receiving parts that come into contact with the protruding parts are provided to outer-pipe elbow sections positioned in the elbow sections, contact surfaces of at least the protruding parts or the receiving parts furthermore being configured from heat-insulating members.
