Self-Closing Valves And Venting Or Aerating Valves
(AREA)
Abstract
Valve for pumping air into sewage treatment tanks, characterized in that it comprises a bell internally to which, and through its upper mouth, air is injected, which exits through a series of slots evenly distributed around the periphery of the mouth lower of the bell in which said air is divided into small bubbles, the air mass reaching said grooves through multiple holes made in the bell, normally sealed by an elastic crown adapted to the conical shape of the surface in which it carries out the sealing, acting as a spring while closing said holes and preventing the penetration of wastewater into the interior of said holes to which it releases, for the passage of air, by action of the pressure of said air.
