That is, the liquid chamber cable 7 is passed through the outer tube 1 that forms the adiabatic vacuum M2 - the shield pipe 13 to which the shield coil 6 is attached is inserted into the outer tube! placed concentrically with
It has a structure in which inner pipes 3 and 4 for transferring cryogenic fluids 5a and 5b such as liquid helium are arranged inside the shield pipe B. These inner tubes 3 and 4 are held in the shield pipe 13 by a plate-shaped spacer 14 which is fixed with screws 15 in a vertically overlapping and divided manner. Here, 8a is a spacer supporting the shield pipe 13, 12a, 12c.

合せ加工に多大な時間を費していた。The above conventional technology does not give consideration to the ease of assembly, and although the spacer 14 can be machined with high dimensional accuracy, the inner diameter accuracy of the shield pipe 13 cannot be increased to the dimensional accuracy of the spacer 14. The final dimensions were determined by matching the dimensions of the shield pipe 14 to the inner diameter dimensions of the shield pipe 13, and performing an actual match. For this reason, a large amount of time was spent processing one combination.
本発明の目的は、組合せ時の合せ加工工数をなくして、
効率よく組立てられる多管式極低温移送配管を提供する
ことにある。The purpose of the present invention is to eliminate the number of man-hours required for assembly when assembling,
An object of the present invention is to provide a multi-tubular cryogenic transfer pipe that can be assembled efficiently.

より、達成さｎる。The above purpose is to provide an outer tube whose inside is vacuum insulated, a shield pipe provided inside the outer tube and arranged approximately concentrically with the outer tube, and an outer tube provided inside the shield pipe. It consists of multiple inner tubes that transport low-temperature fluid, and the multiple inner tubes are covered with laminated insulation material.
This is achieved by partially supporting the laminated insulation by spacers.
シールドパイプの内径精度が粗鳴とも、それ以上に弾性
変形可能な積層断熱材をスペーサによって部分的に支持
することにより、シールドパイプの内径精度誤差が積層
断熱材で吸収されるので。Even if the inside diameter accuracy of the shield pipe is rough, by partially supporting the elastically deformable laminated insulation material with a spacer, the error in the inside diameter accuracy of the shield pipe can be absorbed by the laminated insulation material.
組み合せ時の合せ加工が不要となる。No machining is required when assembling.
以下１本発明の一実施例を第１図および第２図こより説

略同心に配設さｎている。A vacuum layer 2 is formed inside the outer tube 1, and serves as a heat insulating layer from the outside. In this case, a shield pipe 13 with a shield coil 6 for transferring liquid nitrogen Tnia attached to the outer surface by a clamp 11 is arranged within the outer tube 1 by a spacer 8 so as to be substantially concentric with the outer tube 1.

材１２ａ、１２ｂをおのおの外周に装着していを。Inside the shield pipe 13, inner pipes 3 and 4 for transferring a cryogenic fluid 58e5b such as liquid helium or liquid hydrogen, which has a lower temperature, are arranged substantially parallel to each other with a spacer 16 interposed therebetween. The shield pipe 13 is protected against external radiant heat, and the inner pipe 3°4 is protected against external radiant heat.
In order to suppress the intrusion heat from the radiant heat, laminated heat insulating materials 12a and 12b are attached to the outer periphery of each.

弾性変形により行う。In addition, in this case, the inner pipe 3.4 is supported by the shield pipe 1.
This is carried out using the spacer ring 10, which has a spacer pipe 9 attached inside which contacts the outside of the laminated heat insulating material 12b, and the spacer 8 outside of the spacer ring 10. At this time,
A spacer 16 made of a heat insulating material is installed between the inner tubes 3 and 4 to maintain a distance of one interval. The diameter of the spacer ring IO is the same as that of the shield pipe 13, so that the spacer 8 can be used in common and the laminated heat insulating material 12a can be easily wrapped around it. In addition, the diameter of the spacer pipe 9 installed inside is
It is determined based on the relationship between the inner tube 3.4 and the inner diameter of the spacer ring 1G, and the final radial dimension is adjusted by elastic deformation of the laminated heat insulating material ν.

And can be assembled efficiently.
