Description

부품 조합형 노즐댐
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 개량된 부품조합형 노즐댐을 원형부위로 일부 떼어내어 도시한 종래 형식의 핵중기발생기 시스템의 개략적인 입면도
제4도는 개량된 부품조합형 노즐댐이 일체볼트링을 가지는 중기발생기의 노즐에 장착된 상태로서 제2도와 유사한 측면도.
제6도는 밀봉수단 및 경보수단을 도시하며 제5도의 부분을 확대한 단면도.

Claims (4)

  1. 노즐표면에 구멍을 뚫지 않고 또한 발생기 내부로 심각한 돌출부가 생기지 않으면서 일체 볼트링을 가진 중기발생기를 격리시키기 위해 유용하게 사용되는 개량된 부품 조합형 노즐댐에 있어서,
    대체로 원형의 둘레와 일차압력 수령부와이차측을 가지는 본체구조와,
    적오도 3개의 분리된 팽창성 주시 밀봉부와 일차측 가요성 격막과 가요성 부품 접촉영역 밀봉부를 포함하는 과잉 밀봉수단과,
    링에 볼트로 고정되어서 이차측과 결합하는 다수의 독립바아를 포함하는 과잉 지지수단을 구비하는 것을 특징으로 하는 부품조합형 노즐댐.
  2. 제1항에 있어서,
    일차측은 도움을 형성하는 것을 특징으로 하는 부품 조합형 노즐댐
  3. 제2항에 있어서,
    압력 감지수단은 제2팽창성 밀봉부와 제3팽창성 밀봉부 사이에서 증가하는 압력을 감지하는 것을 특정으로 하는 부품조합형 노즐댐.
  4. 제3항에 있어서,
    압력 감지 경보수단은 압력 감지수단이 불필요하게 증가한 압력을 감지할 때 작동되는 것을 특징으로 하는 부품조합형 노즐댐.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
