Abstract

체브 밸브의 구조를 간단히 하기 위해 본 발명은 접시 스프링(10)과 일체적인 밸브폐쇄체(12)를 제안하고 있다. 밸브 폐쇄체(12)는 접시 스프링(10)의 중앙에서 구형 캡 형상으로 구성이 되어 있다. 접시 스프링은 나선 형상의 스프링 웨브(14)를 갖추고 있다.In order to simplify the structure of the valve valve, the present invention proposes a valve closing body (12) integral with the disc spring (10). The valve closure 12 is configured in a spherical cap shape at the center of the disc spring 10. The disc spring has a spiral spring web 14.
