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.

A liquefied hydrogen transport method includes connecting first and second loading arms to the manifold while vacuum insulation double tubes of the first and second loading arms are filled with hydrogen gas and air is mixed in piggyback lines; supplying an inactive gas to one of the piggyback lines of the first and second loading arms and taking in a gas mixture of an inactive gas and air from the other of the piggyback lines of the first and second loading arms; supplying hydrogen gas to one of the piggyback lines of the first and second loading arms and taking in a gas mixture of hydrogen gas and an inactive gas from the other of the piggyback lines of the first and second lading arms; and transporting liquefied hydrogen through any one of the vacuum insulation double tubes of the first and second loading arms.
摘要:
A low temperature fluid dual structure pipe includes: an inner pipe through which a low temperature fluid flows; and an outer pipe externally fitted to the inner pipe with a sealed tubular space therebetween. An inactive gas having a melting point and a boiling point each of which is equal to or higher than a temperature of the low temperature fluid is filled in the tubular space between the inner pipe and the outer pipe. When the low temperature fluid flows through the inner pipe, the inactive gas is liquefied or solidified, and therefore, at least one of a liquefied inactive gas layer and a solidified inactive gas layer is formed on an outer peripheral surface of the inner pipe. As a result, a pseudo vacuum layer that is in a substantially vacuum state is formed in the tubular space.
