ONE PIECE DOUBLE MEMBRANE DIAPHRAGM VALVE |
摘要 |
<p>A one piece double membrane diaphragm including an upper (308) and lower diaphragm membrane (310) joined together by a central section (312) is provided. The upper diaphragm membrane (308) seals against a top sealing surface (222) when the diaphragm is in a first position. The lower diaphragm membrane (310) seals against a bottom sealing surface (224) when the diaphragm is in a second position. The diaphragm may also be made from a resilient material and shaped in such a way as to create a spring force holding the diaphragm into a default position in the valve.</p> |
