配管継手構造。 Vacuum insulation that connects a pair of left and right vacuum insulated piping, which seals the space between the inner tube and the outer tube that is coaxially installed at a constant interval around the outer circumference of the inner tube and maintains it in a vacuum state. The pipe joint structure is such that the inner pipes of the pair of left and right vacuum insulated pipes are respectively protruded from the ends of the outer pipe, and the protruding portions of the pair of left and right inner pipes are butted and joined. A cylindrical fixing part provided with a first exhaust valve at one end of the outer circumferential surface is fitted onto the outer circumferential surface of the outer pipe of the left and right pair of vacuum insulated piping in a joined state, and the fixing part is A sealing material is disposed along the circumference between the inner circumferential surface of both ends and the outer circumferential surface of the outer tube, and this sealing material is disposed along the circumference between the inner circumferential surface of the fixed part and the outer circumferential surface of the outer tube. The outer circumferential surfaces of both ends of the fixing part are tightened and fixed with clamps so that they are in close contact with each other. A second exhaust valve communicating with the inside is provided on the outer peripheral surface of the outer shell, and a porous heat insulating material is filled in the gap formed by the inner pipe, the outer pipe, and the fixing part. With,
A vacuum insulation piping joint structure characterized in that the cavity and the cylindrical space of the outer peripheral shell can be evacuated and depressurized via the first and second exhaust valves.
