Abstract

The nonmetal carbon fiber full-winding high-pressure hydrogen storage bottle inner container bottle opening structure comprises a plastic bottle opening, the end of the plastic bottle opening is sleeved with a metal sleeve piece, and sealing gaskets are arranged at the contact position of the metal sleeve piece and the plastic bottle opening and the contact position of a protruding edge strip and the plastic bottle opening; the device further comprises a fixing sleeve, the fixing sleeve is arranged on the outer side of the top of the metal sleeve in a threaded and sleeving mode, an outer fixing strip is fixed to the inner wall of the protruding note, a gear ring is movably installed in the top of the metal sleeve in an embedded mode, a vertical rod is fixedly installed in a gear, and an inner fixing rod is connected to the side of the interior of the metal sleeve in a penetrating mode through a spring. And the sealing cover is arranged at the bottom position of the vertical rod in a threaded and sleeving manner. According to the nonmetal carbon fiber full-winding high-pressure hydrogen storage bottle inner container bottle opening structure, sealing and fixing of the metal sleeve piece and the plastic bottle opening can be achieved by rotating the fixing sleeve, and meanwhile the sealing effect can be enhanced through the sealing cover by means of internal air pressure.

Description

technical field [0001] The invention relates to the technical field of high-pressure gas storage bottles, in particular to a non-metallic carbon fiber full-wound high-pressure hydrogen storage bottle liner bottle mouth structure. Background technique [0002] High-pressure gas storage cylinder is a container for storing high-pressure gas. The inner liner is widely used due to its light weight and high strength, but the strength of the plastic inner liner seal is low, and it is usually necessary to add a metal bottle mouth for installation to ensure the strength of the bottle mouth, but the existing liner bottle The mouth structure has the following problems in use: [0003] In the bottle mouth structure of the inner tank, in order to ensure the installation, tightening and sealing, it is usually necessary to use a clamping structure, but the existing bottle mouth structure of the inner tank usually adopts the concave-convex matching for direct clamping, which requires a lar...
