Abstract
Description
Claims (2)
- 밸브홀(2)을 구비한 밸브하우징(1)의 하측 내부에 밸브(10)의 설치를 위한 밸브실(3)이 형성되어 있는 체크밸브에 있어서,밸브실(3) 내에 스프링(12)에 의해 탄지되어 밸브홀(2)을 선택적으로 개방시키는 밸브(10)를 평판형으로 형성하고, 상기 밸브(10)의 상면에 밸브홀(2)을 수용하면서 밸브실(3)의 상부벽면에 밀착되는 밀착돌기부(11)를 환형으로 돌출형성하되, 상기 스프링(12)을 원추형으로 형성하여 밸브(10)의 연속동작시에도 스프링(12)이 밸브(10)로부터 이탈되지 않도록 한 것을 특징으로 하는 체크밸브구조.
- 제 1 항에 있어서,상기 밸브실(3)의 하부에 결합되어 스프링(12)을 지지하는 스프링시트(13)를 원판형으로 평평하게 형성한 것을 특징으로 하는 체크밸브구조.
