| Zusammenfassung: | A pressure vessel according to the present invention comprises: a cylinder extending in one direction and having both ends open and empty inside; a closed end that blocks both open ends of the cylinder and is fastened to the inner surface of the cylinder; a cap which supports the closed end in the longitudinal direction of the cylinder and is fastened to the outer surface of the cylinder; a winding wrapped around the cap and the outer surface of the cylinder; and a valve provided at the closed end to store and discharge a fluid. According to the present invention, the pressure vessel can have an increased fatigue strength by supporting the longitudinal stress and the radial stress of the cylinder. Accordingly, the number of times of use of the pressure vessel can be further increased.
본 발명에 따른 압력용기에는, 일방향으로 연장되고 양단이 개방되고 내부가 비어 있는 실린더; 상기 실린더의 개방되는 양단을 막고 상기 실린더의 내면에 체결되는 폐쇄단; 상기 폐쇄단을 상기 실린더의 길이방향 안쪽으로 지지하고, 상기 실린더의 외면에 체결되는 캡; 상기 캡 및 상기 실린더 외면에 접하여 감싸는 권선; 및 상기 폐쇄단에 마련되어 유체를 저장하고 배출하는 밸브가 포함된다. 본 발명에 따르면, 실린더의 길이방향응력 및 방사방향응력을 지지하여 압력용기의 피로강도를 더 크게 할 수 있고, 이에 따라서, 압력용기의 사용횟수를 더 증가시킬 수 있다. |
