    Abstract: The present invention relates to a metal nozzle boss provided with a sealing device, which has highly improved tightness and is combined with a plastic liner of a composite vessel used as a high-pressure vessel. The metal nozzle boss uses an elastic seal ring and a tightening piece in the plastic liner, so that the nozzle boss reliably seals the junction of the nozzle boss and the liner and prevents gas leakage from the vessel. The blade part of the nozzle boss has a dovetail-shaped locking groove, with locking ridges formed in the locking groove. Thus, when the plastic liner is produced by injecting molten resin into the locking groove, the plastic liner is securely combined with the metal nozzle boss. The composite vessel having the metal nozzle boss can be used as a fuel tank for natural gas vehicles or a hydrogen tank for fuel cell vehicles.

    Abstract translation: 本发明涉及一种具有密封装置的金属喷嘴凸台,其具有高度改进的密封性,并且与用作高压容器的复合容器的塑料衬套组合。 金属喷嘴凸台在塑料衬套中使用弹性密封环和紧固件,使得喷嘴凸台可靠地密封喷嘴凸台和衬套的接合部,并防止气体从容器中泄漏。 喷嘴凸台的叶片部分具有燕尾形锁定槽,锁定脊形成在锁定槽中。 因此,当通过将熔融树脂注入到锁定槽中来制造塑料衬套时,塑料衬垫与金属喷嘴凸台可靠地组合。 具有金属喷嘴凸台的复合容器可以用作天然气车辆的燃料箱或用于燃料电池车辆的氢罐。
