AI Technical Summary

Technical Problem

When welding insulating gas cylinders transporting deep-cooled liquid, the prior art is difficult to ensure the high connection strength and thermal insulation performance of the inner liner and the bottle body at the same time, resulting in heat transfer problems.

Method used

Using a vacuum sandwich connection structure between the inner liner and the bottle body, a combination structure of the upper support table, fiberglass pad plate, lower support table and support tube cap is combined with the locking component and fiberglass collar to form a stable connection structure to reduce the Heat conduction and enhance the connection strength through the inlet and outlet pipe.

Benefits of technology

It achieves high connection strength and excellent thermal insulation performance, ensuring low-temperature storage of deep-cooled liquids and reducing heat transfer between the inner liner and the bottle body.

Abstract

The utility model provides a welding heat insulation gas cylinder which comprises an inner container and a cylinder body located on the outer side of the inner container, the inner container is provided with an inner upper sealing head, the cylinder body is provided with an outer upper sealing head located on the outer side of the inner upper sealing head and a distribution head fixedly arranged on the outer upper sealing head, and a connecting structure is connected between the distribution head and the inner upper sealing head. The connecting structure comprises an upper supporting table, a glass fiber reinforced plastic base plate, a lower supporting table and a supporting pipe cap which are sequentially arranged from outside to inside, the supporting pipe cap is arranged in the inner container and fixedly installed on the inner wall face of the inner upper sealing head, and the inner end of the lower supporting table penetrates through the inner upper sealing head from outside to inside and abuts against the supporting pipe cap. The outer end of the upper supporting table is fixedly connected with the distribution head, the glass fiber reinforced plastic base plate is clamped between the inner end of the upper supporting table and the outer end of the lower supporting table, and the upper supporting table, the glass fiber reinforced plastic base plate and the lower supporting table are fixedly connected and locked through a plurality of locking assemblies. The heat transfer between the inner container and the bottle body is reduced while the connection strength between the inner container and the bottle body is ensured.
