Embodiment Construction

[0013] The refillable vertical mobile gas cylinder of the present invention is composed of an austenitic stainless steel inner tank 5, an outer shell 3, a support structure 6 connected to the inner tank, at least one inflation pipe 4 and an exhaust pipe 7, the inner tank The space 35 between the 5 and the shell 3 is a vacuum, the end 41 of the gas-filled tube 4 communicates with the inner tank 5 and the tube body 42 is penetrated in the space 35 .

[0014] The inflation tube 4 includes at least one pipeline, which is arranged between the inner tank 5 and the shell 3 in the form of a spiral curve, and the ends of each pipeline are connected to the bottom of the inner tank 5 .

[0015] The exhaust pipe 7 includes a long pipe 71 and a short pipe 72, the long pipe 71 has a valve on the top end, and the end of the long pipe 71 extends into the position below the inner bag 5, the short pipe 72 also has a valve on the upper end, and The end of the short tube 72 is close to the mouth ...

Abstract

The invention discloses a refillable vertical movable gas cylinder, which comprises an austenitic stainless steel liner, a housing, a support structure, at least one gas tube and an exhaust tube, wherein the support structure is connected with the liner, a vacuum space is formed between the liner and the housing, the tail end of the gas tube is communicated with the liner, and a tube body is arranged in the space. The gas tube of the movable gas cylinder disclosed by the invention penetrates through and is arranged in the space between the liner and the housing, so that the outer surface of the gas cylinder has a simple structure, and the inconvenience caused by the winding of the tube body is avoided in handling and use processes. One end of the support structure is fixed, and the other end of the support structure is not fixed, so that the support performance of a low-temperature insulating gas cylinder can be effectively strengthened. In addition, the liner of the movable gas cylinder disclosed by the invention is made of austenitic stainless steel, so that the movable gas cylinder has sufficient strength, can pass the test of shrinkage deformation of stored liquid after the stored liquid is cooled, and can withstand certain inertial load in a moving process. Therefore, low-temperature gas can be safely and reliably handled.

Description

technical field [0001] The invention relates to a low-temperature heat-insulating gas cylinder. Background technique [0002] Cryogenic insulated gas cylinders are safe, reliable, easy to use, high loading rate and refillable, and have been used to replace traditional Dewar cylinders and high-pressure steel cylinders. As cryogenic liquids play an increasingly important role in the national economy, it can be predicted that cryogenic insulating gas cylinders will be more widely used in national production due to their advantages such as flexible transportation, convenient use, and reliable performance. Cryogenic insulated gas cylinders need to have sufficient strength and be able to withstand the test of shrinkage and deformation of the storage liquid after being cooled, and must also bear a certain inertial load during the movement process. However, the safety, loading rate and gas purity of the existing cryogenic insulating gas cylinders are not ideal, and need to be furth...
