example 1
[0026] The front end of the 450-liter liquefied natural gas (LNG) vehicle gas cylinder adopts this support structure, which can reduce heat transfer, increase strength, and ensure the excellent performance and service life of the product.
example 2
[0028] The upper neck tube of the 200-liter vertical low-temperature insulated gas cylinder adopts this support structure, which can greatly optimize the daily evaporation rate index of the gas cylinder under the premise of ensuring strength. Of course, in order to install a liquid level gauge, etc., holes need to be opened on the cap of the small tube.

An inner container supporting structure of a low temperature insulation air bottle is used to fasten the inner container of the air bottle to the interior of the outside container and supporting it, with the inner supporting structure making of an extension pipe, whose one end connected to the inner sealing joint of the said inner container, the other end sticking to the inner container to seal it, a supporting piece whose one end linked with the outside sealing joint of the said outside container, and the other end sticking to the extension pipe to support and fasten the inner sealing joint. In this way, the supporting structure can not only improves supporting intensity, effectively reducing heat transmission, but also makes the inner and outside container having more compact structures to improve the transmission efficiency.
Description
technical field [0001] The invention relates to a support structure, in particular to an inner tank support structure for a low-temperature heat-insulating gas cylinder. Background technique [0002] Cryogenic insulating gas cylinders are cylinders used for storage and transportation of liquefied natural gas (LNG), liquid oxygen, liquid nitrogen, liquid argon and other cryogenic liquids, especially for the supply of LNG fuel for automobiles, LNG bottled fuel for residential areas and industries Supply, as well as the supply of LNG bottled fuel for electronics, scientific research, chemical industry, welding and other industries and industries. Generally, the known low-temperature insulating gas cylinders are all provided with a double-layer structure including an inner tank and an outer tank, and a vacuum is drawn between the inner tank and the outer tank; The supporting structure connects and fixes the inner tank to the outer tank. Since the support structure has to bear ...
