Abstract

본 저압작동형 역지밸브는 밸브몸체와, 밸브몸체와 결합되어 유조를 형성하는 밸브캡과, 상기 유조에서 설치되어 밸브몸체와 밸브캡을 연통하는 유통공을 갖는 밸브시이트와, 유체의 흐름방향에 따라 탄성변형되어 상기 유통공을 개방, 폐쇄하는 박막의 스커트부를 갖고, 상기 밸브시이트에 결합설치되는 밸브체로 구성되어 작은 압력차에 의해서도 작동되는 것이다.The low pressure actuated check valve includes a valve body, a valve cap coupled to the valve body to form an oil tank, a valve seat installed in the oil tank to communicate with the valve body and the valve cap, and in a flow direction of the fluid. Accordingly, it is elastically deformed and has a skirt portion of a thin film for opening and closing the flow hole, and is composed of a valve body coupled to the valve seat and operated by a small pressure difference.
