Problems solved by technology

Specifically, since the sealing member 4 is made of a rubber material with a short service life, when the durability of the sealing member 4 is reduced, the high-pressure gas in the container still leaks to the outside, and since the durability of the sealing member 4 is reduced, High pressure vessels need to be replaced periodically

Embodiment Construction

[0038] Hereinafter, a high pressure container for a vehicle according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0039] Such as Figure 2 to Figure 5 As shown in , the high-pressure container for vehicles according to the present invention includes: a plastic liner 10 including a through hole 11 provided thereon; The liner 10 is overlapped, wherein the part overlapping with the plastic liner 10 is combined with the plastic liner 10 by thermal bonding; the metal nozzle boss 30 is combined with the plastic sealing member 20 to cover the plastic sealing member 20 overlapping with the plastic liner 10 composite material layer 40 , combined with the plastic liner 10 and the metal nozzle boss 30 to cover the plastic liner and the metal nozzle boss; and the valve 50 screwed to the metal nozzle boss 30 .

[0040] In order to save weight, the plastic liner 10 is integrally formed by blow molding of a p...

Abstract

The present invention has a structure in which a gap does not appear between the plastic gasket and the plastic gasket since the plastic sealing member is bonded to the plastic gasket by thermal bonding, thereby completely preventing the high-pressure gas from leaking to the plastic gasket and the plastic gasket. Seal gaps between components. In addition, since the plastic gasket and the plastic sealing member made of the same material are bonded to each other by thermal bonding, there is no need to use a conventional lower fastening member, and further, there is no need to use a rubber sealing member to maintain airtightness, This contributes to an increase in productivity by reducing the number of parts, weight, cost, and man-hours.

Description

technical field [0001] The present invention generally relates to a high pressure vessel for a vehicle. More particularly, the present invention relates to a high-pressure container for a vehicle, thereby preventing high-pressure gas in the container from leaking to the outside through a gap between a plastic liner and a metal nozzle boss. Background technique [0002] Generally, a compressed natural gas (CNG) vehicle or a hydrogen fuel cell vehicle includes a high-pressure vessel installed therein through which fuel in a vaporized state is pressurized and stored. [0003] The high pressure vessel consists of a plastic liner, a composite layer covering the plastic liner, and a metal nozzle boss. To reduce weight, plastic liners are made from plastic materials such as high-density polyethylene, polypropylene or polyester resins by mixing carbon or glass fibers with a polymer resin such as epoxy for strength The composite material layer is combined with the plastic liner to ...
