Embodiment 1

[0029] Such as Figure 1 to Figure 3 As shown, a multi-channel liquid helium infusion tube includes a first sleeve 1, an intermediate tube 2, and a second sleeve 3 that are connected sequentially and are all hollow. The first sleeve 1 is provided with a first port 11, The second port 12 and the third port 13. The second sleeve 3 is provided with a fourth port 21 and a fifth port 22. The third port 13 and the fourth port 21 are respectively connected to the two ends of the intermediate pipe 2. The first port 11 , the second port 12 , the third port 13 , the fourth port 21 and the fifth port 22 can all be used to pass through the liquid helium infusion pipeline 4 , the liquid helium precooling pipeline 5 , and the helium gas return pipeline 6 .

[0030] In use, the cold box 61 is connected to the first port 11 , the first thermostat 62 is connected to the second port 12 , and the second thermostat 63 is connected to the fifth port 22 . The present invention introduces the liqui...

Embodiment 2

[0042] Such as Figure 1 to Figure 3 As shown, as a further optimization of Embodiment 1, this embodiment includes all the technical features of Embodiment 1. In addition, this embodiment also includes the following technical features:

[0043] A multi-channel liquid helium infusion device, comprising a multi-channel liquid helium infusion tube, a cold box 61 connected to the first port 11, a first thermostat 62 connected to the second port 12, and a fifth port 22 connected to the second thermostat 63.

[0044] The present invention introduces the liquid helium infusion pipeline 4, the liquid helium precooling pipeline 5, and the helium gas return pipeline 6 through the first port 11, the second port 12, and the fifth port 22, thereby realizing the only multi-channel liquid The helium supply interface supplies liquid helium to the two thermostats in different periods. After the initial project installation is completed, the working thermostat can be changed by switching with...

Embodiment 3

[0048] Such as Figure 1 to Figure 3 As shown, this embodiment includes all the technical features of Embodiment 1 and Embodiment 2. On the basis of Embodiment 1 and Embodiment 2, this embodiment provides a more detailed implementation mode.

[0049] The vacuum insulation design of the multi-channel infusion tube, how to install the liquid nitrogen protection screen in the narrow interlayer, the liquid helium supply switching of the two thermostats, and the installation and operation of the other thermostat at room temperature when one thermostat is working are technical problems. .

[0050] The only multi-channel liquid helium supply interface of a 2K cold box 61 of the present invention is that two thermostats (the first thermostat 62 and the second thermostat 63) supply liquid helium in time intervals. After the initial project installation is completed, the working thermostat can be changed by switching the valves (the first valve control device 10 and the second valve cont...

Abstract

The invention discloses a multi-channel liquid helium infusion tube and a liquid helium infusion device.The multi-channel liquid helium infusion tube comprises a first sleeve, a middle tube and a second sleeve which are all hollow and are sequentially communicated, the first sleeve is provided with a first port, a second port and a third port, the second sleeve is provided with a fourth port and a fifth port, and the fourth port is communicated with the middle tube. The third port and the fourth port are connected with the two ends of the middle pipe correspondingly, and the first port, the second port, the third port, the fourth port and the fifth port can be used for allowing a liquid helium liquid conveying pipeline, a liquid helium pre-cooling pipeline and a helium gas return pipeline to pass through. The problems that in the prior art, when helium needs to be conveyed to another thermostat, a liquid helium conveying pipe needs to be replaced, so that the replacement period is long, replacement operation is troublesome, and danger is large are solved.

Description

technical field [0001] The invention relates to the technical field of cryogenic transportation, in particular to a multi-channel liquid helium infusion tube and a liquid helium infusion device. Background technique [0002] During the operation of the existing cryogenic system, the multi-channel liquid helium infusion pipe is connected to the 2×4cells thermostat, and the helium and liquid helium pass through the pre-cooling pipe, liquid infusion pipe and helium gas return pipe to complete the cooling infusion of the thermostat. [0003] In order to reduce the heat leakage of the liquid helium infusion tube itself and reduce the vaporization and evaporation of 2K liquid helium, an 80K liquid nitrogen screen is technically used for heat insulation, and the inner pipe is wrapped with multiple layers of heat insulating materials, and the inner pipe and the atmosphere are wrapped by pipes , Vacuuming further reduces heat radiation. The original multi-channel liquid helium infusi...
