Abstract
A high-pressure composite container is provided. At least a plastic-liner is provided with a plastic shell and a metal end encapsulated by the plastic shell. The plastic-liner of the sealing structure only consists of the plastic shell and the metal end, and the sealing structure is simple. The metal end and a bottle mouth valve jointly compress a sealing ring on the bottle mouth valve, so that the sealing ring forms a stable compression amount, and finally the high-pressure gas cylinder has excellent sealing performance. In addition, the metal end and the plastic shell are well positioned both axially and circumferentially. In the case of high and low pressure and temperature alternation, the relative positions of the metal end and the plastic shell do not change, and a sealing surface of the plastic shell does not deform and dislocate.
