Abstract
The invention discloses a heat insulation connecting device for low-temperature transmission lines. The device comprises left and right low-temperature liquid transmission lines, the left and right low-temperature liquid transmission lines are hermetically jointed by adopting left and right flanges, and a step sealing component is arranged between a right transmission inner tube and a right extending section. The device has simple design structure, greatly reduces difficulty in design of the transmission lines for distant low-temperature liquid transmission, and reduces the emptying and leakage detection costs of the transmission lines.
Description
Technical field
The thermal insulation of transmission line butt joint when the present invention relates to a kind of cryogenic liquide remote transmission, to satisfy the less loss of refrigeration capacity of transmission line, being mainly used in the design aspect of aspect low temperature transmission lines such as experimental setup, bioengineering, mainly is the adiabatic connection set of a kind of low temperature transmission line.
Background technique
Require cryogenic tank away from device for the low temperature test device, when bioengineering is equipped with, this timer moves required cryogenic liquid just must be by remote low-temperature transmission lines transmission, the design of the transmission line of having relatively high expectations for thermal insulation just involves segment design or the problem of global design, if global design will increase the find time operating cost of cost and transmission line of stopping leakage in the roof of transmission line greatly.The transmission line segment design is coupled together by adiabatic plug then, can greatly reduce the insulated design requirement of transmission line, and can reduce the cost of stopping leakage in the roof of finding time of transmission line, therefore for the design of the adiabatic plug of remote low-temperature transmission lines to transmission line design, install, stop leakage in the roof etc. and bring higher practicality.
Summary of the invention
