Abstract

The invention relates to the technical field of hydrogen storage valves, and discloses a valve assembly of a hydrogen storage device of a hydrogen energy automobile. The valve assembly comprises a valve body, a filler cover plate, a valve rod and filler, the filler cover plate covers the top of the valve body and is fixedly connected to the valve body through bolts, the filler is located inside the valve body and covers the lower portion of the filler cover plate, the valve rod penetrates through the filler cover plate and the filler, and the valve assembly further comprises a dismounting part, a connecting block, hydrogen absorption reactors and a negative pressure telescopic pipe; and an internal piston is driven to ascend through rotation of a screw rod, negative pressure treatment is conducted on the interiors of the negative pressure telescopic pipe and the connecting block under the action of the piston, the negative pressure telescopic pipe transversely shrinks under the action of negative pressure, the length of the negative pressure telescopic pipe starts to be shortened, the hydrogen absorption reactors in clamping grooves are pulled to be adsorbed to the two sides of the connecting block, then, a supporting rod can be pulled to take out the hydrogen absorption reactors from the interior of the filler cover plate, and then the hydrogen absorption reactors are replaced, so that the replacement of the whole filler cover plate is avoided, and unnecessary troubles are reduced.

Description

technical field [0001] The invention relates to the technical field of hydrogen storage valves, in particular to a valve assembly of a hydrogen storage device for a hydrogen energy vehicle. Background technique [0002] Hydrogen is a flammable and explosive medium, because of its small molecular diameter, it is easy to leak through the sealing medium. The leaked hydrogen reaches a certain concentration after contacting with the air. Once it comes into contact with an open flame or a high temperature, it will burn and explode. In the valve of the hydrogen storage bottle, due to the continuous opening and closing of the valve, the tightness of the sealing packing inside the valve It will gradually decrease, and eventually develop from a small amount of leakage to a large amount of leakage, such as the hydrogen valve with the function of leaking hydrogen removal with the application number CN201610936892.5, in which the Pd / Pt-Al2O3 catalyst coated on the hydrogen absorption rea...
