The technological scheme of the utility model can also be further perfect:
As preferably, after the docking adapter butt joint, between interface place vacuum tube and cryogen delivery pipe, form a seal space, there is radially accumulation of energy seal ring in this outside, space, and there is end face accumulation of energy seal ring the inboard.If the end-face seal ring on the cryogen delivery pipe damages; Cryogen gets in this space, after vaporization, can produce a large amount of gases, and pressure raises; Too high pressure can destroy the docking adapter structure; For this reason the end face accumulation of energy seal ring of interface and radially the seal space between the accumulation of energy seal ring be provided with outlet pipe, outlet pipe one end links to each other with seal space, one-way valve of another termination.In normal working, peripheral air can not get in the docking adapter from one-way valve, in case the interface seal ring damages, the seal space internal pressure raises, and when pressure surpasses the one-way valve setting, the seal space pressurized gas discharge at once, play the safety protection effect.
As preferably, said end face accumulation of energy seal ring or radially the accumulation of energy seal ring be the low temperature resistant engineering material of cirque structure, innerly embed low temperature resistant metal material spring.After the docking adapter butt joint, the seal ring bi-side are compressed by external force, and its contained spring produces a spot of resiliently deformable, and the elastic force of spring flicks the seal ring both sides, makes two interface reliable sealings.
Radially the accumulation of energy seal ring is used for the sealing at vacuum tube place, prevents that outside air from getting into.
As preferably, said interface is a flanged surface.
As preferably, said bimetallic tube is a concentric tube.
The utility model beneficial effect is:
1, good insulation is adiabatic in working order, and the abutted flange place does not freeze;
2, two pipeline Butt sealing face reliable sealings under normal temperature and low-temperature condition;
3, abutted flange is realized throwing off fast behind the end-of-job.
