Abstract
Description
즉, 상기 보조링(30)에 형성되는 에어공(32)은 전면과 후면에 각각 형성되어 전면에 형성되는 에어공(32)을 통해 유입된 공기가 후면에 형성되는 에어공(32)을 통해 에어시트(20)에 공기를 전달하게 되는 것이다.
Claims (3)
- 밸브몸체(10) 중앙의 게이트(12)가 실린더(S)에 의해 승하강 하면서 메탈시트(15)에 밀착되거나 이탈되어 유통로(13)를 개폐하는 것에 있어서,상기 밸브몸체(10)의 입구측(10a)에는 전방 외주연이 공기압에 의해 팽창하면서 게이트(12)를 메탈시트(15)에 가압하거나 가압 해제하면서 기밀작동하는 기밀부(21)와 외측 중앙을 따라 내측을 향해 에어통로(25)가 형성되는 고무시트(20)와; 공기가 유입되는 상기 에어통로의 입구에 장착되어 에어통로(25) 및 고무시트(20)를 지지하도록 삽입되고 어느 일측에 에어통로와 연통되는 에어공(32)이 형성되는 보조링(30) 및; 상기 고무시트(20)의 외측을 감싸도록 지지 설치되고 그 내측단부(41)와 게이트(12)와 의 간격을 조절하여 불순물의 흐름을 차단하는 시트링(40)을; 조립 설치하여 이루어진 것을 특징으로 하는 시트 팽창식 본네트형 나이프 게이트 밸브장치.
- 제1항에 있어서,상기 고무시트(20)의 기밀부(21)는 중앙에 공기압에 의해 신축작동하는 기밀돌기(22)를 돌설하여 이루어진 것을 특징으로 하는 시트 팽창식 본네트형 나이프 게이트 밸브장치.
- 제2항에 있어서,상기 기밀부(21)의 기밀돌기(22) 내외측에는 기밀돌기(22)보다 더 돌출되는 형태로 보조돌기(23)를 돌설하여 이루어진 것을 특징으로 하는 시트 팽창식 본네트형 나이프 게이트 밸브장치.
