Abstract
Description
Claims (3)
- 확대 관로에 설치되어 한쪽 방향으로만 유체가 흐르도록 개폐하는 체크 밸브에 있어서,상기 체크밸브는 상기 확대 관로 입구에 위치되어 작용되는 유압에 의해 개폐되는 제1밸브판과, 상기 제1밸브판 뒤쪽에서 길게 설치된 밸브 로드와, 상기 밸브 로드 중간에 상기 확대 관로를 막도록 위치되고 유체가 통과되는 다수의 구멍이 형성된 막이판, 상기 제1밸브판과 막이판 사이에 위치되어 상기 제1밸브판을 원위치시키는 리턴 스프링과, 상기 밸브 로드에 고정되고 상기 제1밸브판과 동시에 이동되어 상기 막이판의 구멍을 개폐하는 제2밸브판으로 구성된 것을 특징으로 하는 다단계형 체크 밸브.
- 제1항에 있어서,상기 제2밸브판은 상기 밸브 로드에서 상기 막이판의 구멍 방향으로 절곡되게 돌출된 연결부와, 상기 연결부 끝단에 설치되어 상기 막이판의 구멍을 개폐하는 개폐구로 구성된 것을 특징으로 하는 다단계형 체크 밸브.
- 제1항 또는 제2항에 있어서,상기 제2밸브판은 유체의 흐름 저항에 최소화되도록 상기 밸브 로드에서 방사형으로 배열되어 설치된 것을 특징으로 하는 다단계형 체크 밸브.
