Title:
PRESSURE VESSEL
Document Type and Number:
WIPO Patent Application WO/2017/200206
Kind Code:
A1
Abstract:
The present invention relates to a pressure vessel. Particularly, the pressure vessel according to the present invention comprises: a nozzle boss provided with a hollow neck part, a flange part extended outward from the neck part, and a hollow protrusion part extended from an end part of the neck part; a liner coupled to the flange part of the nozzle boss and providing a fluid-filling space therein; and a sealing part, a pressurization part, an elastic member and a pressurization-enhancing part which are sequentially inserted from the outside along the outer circumferential surface of the protrusion part. Here, the sealing part blocks the direct contact of the fluid with respect to the boundary between the flange part and the liner, thereby preventing the leakage of the fluid through the boundary; the pressurization part pressures the sealing part in the upward axial direction; the pressurization-enhancing part is coupled to the protrusion part, thereby providing a pressurizing force to the pressurization part and maintaining the force; and the elastic member is provided between the pressurization part and the pressurization-enhancing part. The pressure vessel according to the present invention is provided with the elastic member between the pressurization-enhancing part and the pressurization part, such that, in case of repeated use, the reduction of the fixing force for maintaining the coupling force between components, that is, the nozzle boss and the liner, can be maximally delayed, and a tightly sealed structure enabled by the sealing part can be maintained via constant elasticity.
