ABSTRACT:
An improved reversible quick exhaust valve is provided which comprises, in combination, a valve housing and a flexible resilient valve member disposed in the housing. The housing has a hollow interior and defines and entry port and first and second exit ports. A valve support is positioned in the interior to define with the housing a narrow passageway between the inlet port and the first exit port. The valve member is in the form of a flexible plate having a depending wall. The plate is disposed over one end of the valve support and the depending wall extends into the passageway. The plate blocks passage of liquid from the inlet port to the second exit port. The depending wall flexes during passage of the liquid from the inlet port into the housing and through the passageway to permit the liquid to pass out of the housing through the first exit port. When liquid is passed into the housing from the first exit port, the valve member is displaced sufficiently to permit the liquid to pass out of the housing through the second exit port but seals the first exit port from the inlet port. The valve is simple, efficient and utilizable in a liquid treating system such as filtration systems for agricultural and industrial water and the like.
