Problems solved by technology

By evacuating the space between the vessel and the jacket and placing an insulating medium in it such that the insulating medium prevents the transfer of heat to the cryogenic liquid, which can cause vaporization and expansion, affects the safety of the vessel and cannot be guaranteed against said vessel The effect of dynamic monitoring is greatly detrimental to prevent heat penetration while setting efficient isolation
[0005] In order to solve the ubiquitous problems in the field such as the lack of safety monitoring of the container, the inability to perform diagnosis, the inability to timely feedback the pressure value of the container, and the poor heat insulation effect of the container, etc., the present invention is made

Description

technical field [0001] The invention relates to the technical field of pressure vessel detection, in particular to a low-temperature pressure vessel diagnosis and monitoring system. Background technique [0002] Fuel stored in non-operating vehicles heats up slowly when the insulation of the pressure vessel is insufficient. Here, the pressure in the pressure vessel rises gradually at the same time. When the limit pressure is exceeded, the fuel must escape through the safety valve to prevent the cryogenic pressure vessel from bursting. Pressure vessels therefore require excellent thermal insulation in order to prevent as much as possible the penetration of undesired heat into the cryogenically stored medium. [0003] Such as CN102393767A The prior art discloses a low-temperature valve detection device and its use method. After the pressure of the helium cylinder is low, it will be introduced into the low-pressure tank, and then the low-pressure tank will be pressed into th...
