Problems solved by technology

[0004] One is that the support structure between the inner container and the outer container will produce a certain amount of heat transfer, which affects the insulation effect of the ultra-low temperature liquefied gas pressure vessel
[0005] Second, the cooling capacity of the liquefied gas released under overpressure is not fully utilized, which will also affect the insulation effect of the ultra-low temperature liquefied gas pressure vessel

Abstract

The ultralow-temperature liquefied gas pressure container comprises an inner container body, an outer container body and a supporting assembly supported between the inner container body and the outer container body, and the supporting assembly comprises a first supporting ring with an annular hollow inner cavity and a second supporting ring with an annular hollow inner cavity. A gas throttle pipe is arranged between the annular hollow inner cavities of the first support ring and the second support ring; a first gas pipeline is led out of the upper gas space inside the inner container, the first gas pipeline enters the annular hollow inner cavity of the first supporting ring after being led out, and a second gas pipeline is led out of the annular hollow inner cavity of the second supporting ring; a first valve is arranged on the first gas pipeline, a second valve is arranged on the second gas pipeline, a branch gas pipeline is arranged at a section of position between the second valve and the outer container on the second gas pipeline, and a third valve and a vacuumizing device are sequentially arranged on the branch gas pipeline. The heat insulation effect of the ultralow-temperature liquefied gas pressure vessel is improved.

Description

Technical field [0001] The present invention relates to the field of low temperature pressure vessels, and more particularly to an ultra-low temperature liquefied gas pressure vessel for increasing the heat insulating effect. Background technique [0002] Ultra-low temperature liquefied gas storage pressure vessels are a deep-cooling pressure vessel for storing ultra-low temperature liquefied gas, which uses a double layer structure, including a sewer and outer container, an extension, and an outer container to form a vacuum interlayer space to isolate external heat. Pass to ensure the safety of low temperature liquefied gas in the contentor. In order to improve the heat insulating performance, it is generally wound around the insulation insulation material to reduce heat transfer, convection, and radiation to reach heat insulation, and store low temperature liquid. The arrangement of the insulation of the inside the can body in the interlayer vacuum and the insulation of the hea...
