Multi-channel inner pipe supporting structure

Abstract

The invention discloses a multi-channel inner pipe supporting structure. The multi-channel inner pipe supporting structure comprises a supporting plate and connecting parts; the supporting plate takes a line passing through the center as a symmetric line, and quasi-circular structures each with two notches are symmetrically formed in the two ends of the supporting plate correspondingly. the supporting plate vertically penetrates through a main pipe through hole with the axis on the symmetric line of the four notches. the supporting plate is further provided with two first auxiliary pipe holes which are through up and down. the two first auxiliary pipe holes are symmetrical relative to the symmetrical line of the four notches; the first auxiliary pipe holes are located in one end of the supporting plate; the supporting plate is further provided with two second auxiliary pipe holes; the two second auxiliary pipe holes are symmetrical about the symmetrical line of the four notches; second auxiliary pipes are adjacent to the first auxiliary pipe holes respectively and are arranged outside the two first auxiliary pipe holes; cooling pipe avoiding positions are arranged at the other end of the supporting plate; and the connecting parts connected with a cold shield is fixed to the supporting plate at the edges of the notches. According to the multi-channel inner pipe supporting structure, the supporting effect is good, and system heat leakage is reduced.

Description

technical field [0001] The invention relates to the technical field of pipe support, in particular to a multi-channel inner pipe support structure. Background technique [0002] Large scientific devices all involve the field of low-temperature superconductivity. As the key equipment for the transmission of low-temperature fluid medium for low-temperature superconductivity—multi-channel low-temperature transmission pipeline: a vacuum outer tube, forming a variety of temperature zones / transmission of different fluid media has the following features Advantages Low heat leakage: Similar to cable resistance, the greater the cable resistance, the greater the power transmission loss. In other words, the greater the heat leakage of the multi-channel itself, the lower the effective transmission efficiency of the pipeline. The heat leakage of multi-channel pipelines is about 20% of that of ordinary single-channel pipelines, which has obvious advantages in low-temperature fluid transpo...

Problems solved by technology

[0005] But there are the following defects: the fixed point force arm is too long, it is easy to cause system instability; the fixed point is subjected to too much torque, it is easy to cause fixed point instability; increase system heat leakage: the connection and fixation between different temperature zones will inevitably cause system heat leakage increase; complex structure: increase the fixed structure between the cold screen and the inner pipe, resulting in the complexity of the piping system, increasing the assembly work, and increasing the requirements for the system assembly tolerance
