VALVE WITH WELDED DIAPHRAGM TO ASSIST OPENING FORCE

A springless diaphragm valve and an associated diaphragm have increased lifting force for opening the valve. In an embodiment, the diaphragm is a diaphragm assembly of a domed diaphragm having a surface that comes in contact with the valve seat to close the valve, and a biasing member which may also...

Zusammenfassung:	A springless diaphragm valve and an associated diaphragm have increased lifting force for opening the valve. In an embodiment, the diaphragm is a diaphragm assembly of a domed diaphragm having a surface that comes in contact with the valve seat to close the valve, and a biasing member which may also be a domed diaphragm. The diaphragm has a central portion that is attached to the biasing member, for example by a weld. The diaphragm and the biasing member may be nested together, and each may be circular and include a domed portion. The weld is preferably in a central portion of the diaphragm near the apex or geometric center of the diaphragm. 무 스프링 다이어프램 밸브 및 연관된 다이어프램은 밸브를 개방하기 위한 증가된 리프팅 힘을 갖는다. 일실시예에서, 다이어프램은 밸브를 폐쇄하기 위해 밸브 시트와 접촉하는 표면을 갖는 돔형 다이어프램과, 또한 돔형 다이어프램일 수 있는 편향 부재의 다이어프램 조립체이다. 다이어프램은 예를 들어 용접에 의해, 편향 부재에 부착되는 중앙 영역을 갖는다. 다이어프램 및 편향 부재는 함께 상주될 수 있고, 각각은 원형일 수 있고, 돔형 부분을 포함한다. 용접은 바람직하게 다이어프램의 정점 또는 기하학적 중심 근처에서 다이어프램의 중심 부분에 있다.
