VACUUM RELEASE VALVE AND METHOD |
摘要 |
<p>A vacuum release valve and method are defined. The valve 10, 100, 200 is positioned on a line L between a pool suction inlet I and a pump PU for pumping pool liquid from the inlet and along the line L. The valve 10, 100, 200 includes a valve member 24, 108, 214 that is urged by the pump into a sealing position during normal pumping of pool liquid from the inlet to the pump, so that pool liquid does not flow across the valve. When a predetermined level of vacuum is induced in the line, the valve member is moved out of the sealing position by the vacuum so that a fluid is allowed to flow through the valve to release the vacuum.</p> |
