A ROCKER TYPE DIAPHRAGM VALVE |
摘要 |
<p>A rocker type diaphragm valve is disclosed. The diaphragm (428) in the diaphragm valve is asymmetric and the stroke of the diaphragm is offset from the center of the diaphragm. The two sealing surfaces (318, 320) that the diaphragm acts against form two planes that make an angle with respect to ones another. The diaphragm (428) may be fabricated in only one piece. The diaphragm (428) 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> |
