Device backflow of hydraulic valves for siphon having a cartridge with flat plates for flow control.

摘要

A hydraulic GRIFFIN READY to receive a cartridge (81) having ORGANS OF CONTROL FLOW BY WAY OF PLATES PLANAS (102,103) MATERIAL HARD, and having a fitting body (81) and a cover JOINABLE (86), IN WHAT ARE FEW STEPS (87) ambient air inlet so as to correspond to the PATA (86) GRIFFIN, AND A flapper Unidirectional (89) relative to the elastic lip (90) is installed inside TOP between an outer region (85) GRIFFIN, which communicates with the output FLOW (107) GRIFFIN. THIS CLAPPER Unidirectional (89) relative to LIP ELASTICO is arranged such that it remains closed so Stalls as the pressure in the lower region (84) GRIFFIN not less than atmospheric pressure REINANTE in the outer region (85 ) GRIFFIN, which opens automatically when the pressure decreases in the lower region (84) GRIFFIN, even slightly, below atmospheric pressure. THIS WAY, YOU MAY NOT OCCUR IN CONSIDERABLE DEPRESSION outflow (107) GRIFFIN, so that prevents anything from siphoning.
