ABSTRACT:
A Venturi vent valve is disclosed suitable for relieving pressure differentials in sewer systems and preventing the escape of odorous gases. The valve consists of a flared tube containing a conical valve so that the annulus forms a Venturi chamber. The conical valve is mounted axially on a rod that engages in bushes attached to the tubular body and an annular base plate and constrains the valve to move axially. The conical valve rests on a rubber washer secured and sealed to the tubular body by the base plate and prevents the escape of fluids by its own weight. The conical valve lifts off the rubber washer to admit a flow of air when the pressure in the sewer system is less than ambient and the valve opening is maintained by the pressure differential, the venturi effect and the viscous forces acting on the conical valve.
