Claims (1)
- 고압 가스에 노출되는 부재에 형성된 장착 구멍과, 이 장착 구멍에 장착되는 장착 부품 사이의 고리모양 간극을 밀봉하는 밀봉장치로서,
상기 장착 부품의 외주면 측에 형성된 고리모양 홈에 장착되는 밀봉장치에 있어서,
상기 고리모양 홈 내에서 고압 가스의 압력을 받는 측에 설치되는 수지로 만들어진 실 링과,
상기 고리모양 홈 내에서 상기 실 링에 대하여 고압 가스의 압력을 받는 측과는 반대측에 설치되는 고무 모양 탄성체로 만들어진 탄성 링을 구비하되,
상기 실 링은, 외주면 측에는 상기 장착 구멍의 내주면에 밀착하는 원기둥면 부분을 갖고, 또한 내주면 측에는 고압 가스의 압력을 받는 측에서 상기 고리모양 홈의 홈 바닥에 밀착하는 원기둥면 부분과, 상기 반대측에서 그 반대측으로 향함에 따라 직경이 확대되는 경사면 부분을 가지고 있으며,
상기 탄성 링은, 그 적어도 일부가 상기 경사면 부분과 상기 고리모양 홈의 홈 바닥 사이에 끼워넣어짐으로써, 상기 실 링에서의 상기 반대측의 부위를 외주면 측을 향해 꽉 누르도록 배치되는 것을 특징으로 하는 밀봉장치.
