Problems solved by technology

The material of the support tube 4 has the characteristics of low thermal conductivity, but at the same time, the strength of this material is low. Therefore, in order to achieve the strength required by the design, the structural size of the support tube 4 must be increased, which in turn leads to heat transfer. Increased Negative Effects
In addition, during the transportation and use of cryogenic insulated gas cylinders with traditional support structures, the end of the metal support ring 3 is ground against the support tube 4 due to continuous vibration, resulting in defects such as local wear of the support tube 4

Embodiment Construction

[0014] Please refer to FIG. 2 for the supporting structure of the present invention. The present invention uses a solid metal rod or a hollow metal tube as the supporting tube 4 . The inner head 1 is provided with an insertion hole 7 through which the first end A of the support tube 4 is inserted into the inner head 1 . A cap 8 is installed inside the inner head 1 to fix the first end A of the support tube 4 , so that one end of the support tube 4 is fixed on the inner head 1 . A support frame 5 is fixed inside the outer sealing head 2 , and an insertion hole 6 is formed on the support frame 5 . The insertion hole 6 on the support frame 5 is opposite to the insertion hole 7 on the inner head 1, so that the second end B of the support tube 4 is inserted into the insertion hole 6 on the support frame 5, thereby, the support tube 4 is fixed in the inner seal Between head 1 and outer head 2. The support frame 5 may be composed of a horizontal support frame 5a and a vertical supp...

Abstract

A supporting structure for a low temperature thermal insulation air bottle between the inner container and the outside housing of the said air bottle, comprises a supporting pipe that sticks to the No.1 end of the inner sealer of the said inner container, a pipe cover that is located at the inner side of the inner sealer and fastens the No.1 end of the said supporting pipe to the inside of the said inner sealer, a support bracket that is set at the inside of the outside sealer of the said outside housing with inserting holes on it, with the No.2 end of the said supporting pipe inserted into the inserting holes of the said support bracket. The invention can not only improves the supporting strength but also reduce the transmission of heat.

Description

technical field [0001] The invention relates to a supporting structure of a low-temperature heat-insulating gas cylinder, in particular to a supporting structure supported between an inner tank and an outer shell of a low-temperature heat-insulating gas cylinder. Background technique [0002] Typically, cryogenically insulated gas cylinders are designed with a double-layer vacuum structure. Its liner is fixed in the shell through the supporting structure. This requires the supporting structure to have sufficient strength to withstand the external forces generated during transportation and use; in addition, since the inner tank of the cryogenic insulating gas cylinder is filled with cryogenic liquid, in order to reduce the evaporation loss caused by heat transfer, the supporting structure is also required It must have the performance of small heat transfer. The traditional supporting structure is shown in Fig. 1, a metal support ring 3 is welded on the outside of the inner ...
