Description

Technical Field

[0001] The utility model relates to the technical field of solid hydrogen storage, in particular to a valve of a solid hydrogen storage device. Background Technique

[0002] Hydrogen (H2) is a highly efficient clean energy source, and hydrogen storage technology plays an important role in the practical application of hydrogen energy. Traditional hydrogen storage methods are to compress and store gaseous hydrogen, which has poor safety and small storage capacity, or to freeze hydrogen to make it liquefied for storage, with relatively high costs. Currently, the most advanced hydrogen storage method is to use solid hydrogen storage materials to absorb and store hydrogen.

[0003] When existing solid hydrogen storage devices are in use, valves are generally provided on the surface to control exhaust. However, when the existing valves are fixedly installed with the solid hydrogen storage device, they are usually docked through the flange on the valve and the flange on the intake pipe of the solid hydrogen storage device, and then fixed with bolts. This installation method has low efficiency and is not convenient for quick installation. Therefore, we propose a valve for a solid hydrogen storage device. Content of the Utility Model
