플러그 제거방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 점선에 의하여 도시된 변위된 코운위치와 함께 증기 발생기 튜브에서 내부 나사로 된 플러그의 부분단면 정면도.
제2도는 점선에서 최초 팽창된 나사로 된 플러그와 실선에서 신장 및 방사상으로 감축된 것을 나타낸 제1도에서 도시한 플러그 형태의 개략도.
제3도는 선 3-3을 따라 취한 제2도 개략도의 단면도.
제4도는 신장단계의 수행을 위한 위치에서 튜브 신장기 및 변위된 코운에 의한 제1도와 유사한 도면.
제5도는 변위 가능한 코운과 함께 교대의 내부 나사로 된 플러그의 도면.
* 도면의 주요부분에 대한 부호의 설명
10 : 튜브 시이트 부분 14 : 튜브
20,20' : 플러그 22 : 내부공동
24 : 내부 나사부분 26 : 테이퍼면
30 : 코운 40 : 플러그 신장기
42 : 중공 어댑터 부재 52 : 단부 패드

Claims (7)

  1. 제1경도를 갖고 나사부분과 보다 적은 제2경도의 연화된 플러그를 방사상으로 팽창시키고 이를 결함있는 튜브와 밀폐결합 상태로 유지하는 힘의 성분을 발생하도록 플러그 공동의 내부 테이퍼면을 따라서 이동하도록 보다 큰 제2의 경도의 변위 가능한 코운을 수용하는 부분을 갖는 내부공동을 포함하는 증기발생기 튜브용 내부나사 플러그를 제거하는 방법에 있어서, 내부공동내에서 방사상으로 팽창된 위치로부터 변위 가능한 코운을 이동하는 단계와, 플러그를 신장시키도록 공동내에서 플러그에 힘을 길이방향으로 적용하는 단계와, 튜브로부터 플러그를 견인하는 단계를 포함하는 것을 특징으로 하는 내부나사 플러그 제거방법.
  2. 제1항에 있어서, 플러그를 신장시키기 위해 공동내에서 플러그에 힘을 길이방향으로 적용하는 단계에 의해 플러그 직경이 감축되는 것을 특징으로 하는 방법.
  3. 제2항에 있어서, 플러그에 힘을 길이방향으로 적용하는 단계는 나사부분과 변위 가능한 코운 사이에 힘을 적용하는 단계를 포함하는 것을 특징으로 하는 방법.
  4. 제3항에 있어서, 나사부분과 변위가능한 코운사이에 힘을 적용하는 단계는 내부공동의 나사부분에서 내외부 나사 어댑터를 설치하는 단계를 포함하는 것을 특징으로 하는 방법.
  5. 제4항에 있어서, 플러그에 길이방향으로 힘을 적용하는 단계는 내외부 나사로 된 어댑터와 변위 가능한 코운사이에 힘을 적용하는 단계를 포함하는 것을 특징으로 하는 방법.
  6. 제5항에 있어서, 튜브로부터 플러그를 견인하는 단계는 어댑터에서 힘의 적용단계를 포함하는 것을 특징으로 하는 방법.
  7. 제5항에 있어서, 내외부로 나사로 된 어댑터와 변위가능한 코운 사이에 힘을 적용하는 단계는 코운에 대하여 신장된 부재로부터 그리고 플러그 공동의 내면에 대해 코운으로부터의 힘을 적용하여 나사 어댑터의 내부나사와 결합하도록 신장된 부재를 비틀어서 플러그를 신장시키는 단계를 포함하는 것을 특징으로 하는 방법.
