Abstract

파이프 조인트 유체통로로서 축방향으로 형성된 관통구멍(12)을 가진 조인트 몸체(16), 조인트 몸체(16) 상에서 나사결합되어 파이프(20)를 조인트 몸체(16)에 연결하는 너트(22); 및 환형의 단표면(24)에 의해서 조인트 몸체내에 형성된 구멍의 바닥(26)에 대해서 유지하고 소정의 각도로 경사진 팽창부분을 가진 슬리브(28)로 구성되어 있다. 너트(22)는 방사상 내부 파이프 프레서(40)를 그 본래의 형상으로 복귀시키는 탄성력하에서 파이프(20)의 끝을 상기 슬리브(28)에 대해 가압시키기 위하여 너트(22)가 조인트 몸체(16)에 점진적으로 나사 결합될 때 팽창부분(32)에 대한 보충형상으로 구부러지고 휘여지는 방사상 내부 파이프 프레서(40)를 가지고 있다.
