Description
Claims (4)
- 유체가 흐르는 관로에 설치되어 역류를 차단하고 한 방향으로만 흐르게 하는 체크밸브를 형성함에 있어서,상기 체크밸브의 케이싱을 출구(11)를 갖는 상부케이싱(10)과 입구(21) 및 밸브시트(22)를 갖는 하부케이싱(20)으로 분리 형성하여 볼트(30)로 체결하고, 상기 상하부케이싱(10,20)의 출입구(11,21)에는 지지리브(12,23)에 의해 지지되는 원통형의 가이드부(13,24)를 일체로 형성하여 가이드부싱(40,50)을 삽입하며, 상기 밸브시트(22)에 안착되는 밸브체(60)의 상하단에는 가이드부싱(40,50)에 끼워지는 구동축(61,62)을 형성하여서 된 것을 특징으로 하는 체크밸브.
- 제 1항에 있어서, 상기 상부케이싱(10)의 내부 상단에는 밸브체(60)의 승하강시 상승량을 제한하기 위한 복수개의 스토퍼돌기(15)가 형성된 것을 특징으로 하는 체크밸브.
- 제 1항에 있어서, 상기 가이드부싱(40,50)은 열가소성 고성능 수지인 폴리에칠렌계의 수지를 원료로 하여 만든 특수 엔지니어링 플라스틱의 일종으로 열가소성 고성능 수지인 것을 특징으로 하는 체크밸브.
- 제 1항에 있어서, 상기 상부케이싱(10)의 가이드부(13)와 밸브체(60) 사이에 원뿔형 코일스프링(70)을 탄설된 것을 특징으로 하는 체크밸브.
