Abstract

The invention relates to the technical field of high-pressure hydrogen storage containers, and discloses a high-pressure hydrogen storage container with sealing structures at two ends. The high-pressure hydrogen storage container comprises a hydrogen storage cylinder, plungers mounted in inner holes at the two ends of the hydrogen storage cylinder, ejecting rings mounted at orifice parts of the two ends of the hydrogen storage cylinder and used for ejecting against the plungers, and tensioning devices for axially tensioning the plungers on the ejecting rings; sealing rings are arranged between the ejecting rings and the plungers; and low-hydrogen-embrittlement stainless steel metal overlaying layers are arranged on the surfaces of the inner holes of the hydrogen storage cylinder and the surfaces of the plungers. The high-pressure hydrogen storage container prolongs the product life period, improves the product reliability, and facilitates the product detection and maintenance after use.

Description

technical field [0001] The invention relates to the technical field of high-pressure hydrogen storage containers, in particular to a high-pressure hydrogen storage container with sealing structures at both ends. Background technique [0002] The high-pressure hydrogen storage container belongs to the hydrogen gas storage equipment of the hydrogen refueling station, which is mainly to meet the storage needs of the compressor in the 70MPa hydrogen refueling station after compressing hydrogen. [0003] The high-pressure hydrogen storage container in the prior art has the following problems: [0004] One is the existing high-pressure hydrogen storage container, whose overall structure is a steel inner container + laminate wrapping structure, which has low fatigue strength, fewer filling times, and a shorter product life cycle, generally only 10 years. [0005] The second is that the high-pressure hydrogen storage container has many laminated layers, large wall thickness, and he...
