Detachable mechanism used for installing low-temperature superconducting magnet refrigerator

Abstract

A detachable mechanism used for installing a low-temperature superconducting magnet refrigerator comprises a connection flange connected with the refrigerator. The connection flange is connected with a supporting flange through a corrugated pipe, a primary cooling pipe is connected with the supporting flange and a cold shield flange respectively, the upper end of a secondary cooling pipe is connected with the lower portion of the cold shield flange, and the lower end of the secondary cooling pipe is communicated with the inside of a helium tank. The refrigerator and components of the refrigerator can be conveniently mounted and dismounted through commonly-used sealing rings and bolts, and meanwhile a sealed space environment of the components can not be damaged. The refrigerator still can effectively play a refrigeration role through the corrugated pipe, the cold shield flange, the cooling pipes and other parts. The detachable mechanism is simple and compact in structure, simple in manufacturing technology, low in cost, good in interchangeability, low in maintenance cost, long in service life, good in universality, and capable of being modularized.

Description

technical field [0001] The invention belongs to the technical field of installation of a low-temperature superconducting magnet refrigerator, and in particular relates to a detachable mechanism for installing a low-temperature superconducting magnet refrigerator. Background technique [0002] For the low temperature superconducting magnet system, the superconducting coil is in a certain low temperature environment so as to achieve the superconducting working state and other expected performances. If the temperature rises, the quenching phenomenon will occur in the superconducting coil, so that the superconducting magnet equipment cannot be used. Its normal working performance may even cause safety accidents. Therefore, in order to ensure a specific low temperature environment, liquid helium is injected into the closed space where the superconducting coil is located, and then the liquid helium is made to achieve zero volatilization through a specific method, thereby ensuring ...
