Abstract

본 발명은 고압력 개스 용기 밸브에 요구되는 조건을 만족시키고 지진과 같은 재난시 발생하는 화재 또는 폭발과 같은 사고를 미연에 방지하는 밸브 통합 시스템에 관한 것이다.
볼의 정상적인 작동 상태에서의 고정 위치와 비정상적인 작동 상태에서의 개스 차단 위치 사이에서 가동 가능한 볼은, 안전 밸브로 이르는 분기점과 폐쇄 밸브 사이의 개스 통로내에 제공된다. 폐쇄 밸브를 향하여 좁아지는 통로를 갖고 있는 테이퍼부는 개스 통로를 차단하는 위치부근의 개스 통로내에 제공되어 볼이 상기 테이퍼부에 대해 접하여 비정상적인 개스 유출시 개스 통로를 차단한다. 더욱이, 용기 밸브가 차단되는 상태에서는, 폐쇄 밸브의 시트 패킹 말단부가 볼에 대해 접하여 테이퍼부와 볼 사이에서 공간을 형성한다. 주변을 향하여 상승된 우산 프레임의 형태로 볼 리시버는 볼의 정상적인 작동 상태에서 고정 위치에 제공된다.

Description

재난에 대비한 엘피(LP) 개스 용기 밸브
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 실시예를 나타내는 정단면도이다.
제4도는 (비정상적인 개스 유출시)스탑 볼의 작동을 예시한다.
제5도는 (잔류개스의 회수시)에 스탑 볼의 작동을 예시한다.
제6도는 스탑 볼의 정상적인 위치에 대한 잘못된 세팅으로 인해 작동이 불가능 상태를 예시한다.

Claims (5)

  1. 밸브 배출구에 이르는 개스 통로를 개방/폐쇄하는 폐쇄 밸브와 비정상적인 개스 압력이 상승에 반응하여 작동되는 안전 밸브를 포함하는 프로판 개스 용기상에 장착된 용기 밸브로서의 LP 개스 용기 밸브에 있어서, 정상적인 작동 상태에서의 고정 위치와, 상기 개스 용기에서 상기 안전 밸브로 이르는 분기점과 상기 폐쇄 밸브 사이에 있는 용기 밸브 배출구까지 이르는 개스 통로내에서의 비정상적인 작동 상태에서의 개스 차단위치를 갖고, 상기 고정 위치와 개스 차단 위치 사이에서 가동 가능한 볼과, 상기 폐쇄 밸브를 향하는 통로에서 좁아지는 상기 개스 차단 위치 부근에 있는 개스 통로내에 제공된 테이퍼와, 상기 볼이 상기 테이퍼부에 접하여 용기 밸브 배출구로 향하는 상기 개스 용기로부터 비정상적으로 개스가 유출할 때 개스 통로를 폐쇄하는 것을 특징으로 하는 재난에 대비한 LP 개스 용기 밸브.
  2. 제1항에 있어서, 폐쇄 밸브가 차단되면, 폐쇄 밸브의 시트 패킹의 말단부는 볼에 대해 접하여 테이퍼부와 볼사이에 공간을 형성하는 것을 특징으로 하는 재난에 대비한 LP 개스 용기 밸브.
  3. 제1항 또는 제2항에 있어서, 볼을 수용하는 낮은 중앙부와 이 중앙부로부터 주변부로 향하는 상승부를 갖는 우산 프레임 형태의 볼 리시버는 개스 통로내에 제공되어 볼의 정상적인 작동상태에서 고정위치에 있게 되는 것을 특징으로 하는 재난에 대비한 LP 개스 용기 밸브.
  4. 제1항 내지 제3항중 어느 한 항에 있어서, 상기 안전 밸브는 볼의 정상적인 작동 상태에서의 고정 위치와 비정상적인 작동 상태에서의 개스 차단 위치 사이에서 4㎜또는 그 이상의 거리를 제공할 수 있도록 배치된 것을 특징으로 하는 재난에 대비한 LP 개스 용기 밸브.
  5. 제1항 내지 제4항에 있어서, 볼의 직경은 8.17㎜∼10㎜, 테이퍼 부분의 최소 직경은 7.5㎜∼8㎜이며, 테이퍼 부분까지 이어지는 개스 통로 구경은 13㎜ 또는 그 이상으로 설정된 것을 특징으로 하는 재난에 대비한 LP 개스 용기 밸브.
