Auto-aerating plant for drinking water supplies - has centralised battery of aerators with common dispersal conduit

摘要

Auto-Aerating plant for drinking water supply pipes, is designed to centralise the aeration of supply e.g. for a multi-storey building, and constitutes a battery of aerators traversed by rising mains and featuring a common drainage collection and dispersal conduit. Each aerator embodies a means of collecting the water produced by the process with means of extraction and limitation. Pref. the limiter is uniquely common to all aerators, and comprises a float valve with poppet valve hanging float and closes onto its sealing seat either when aerators penetrate the drainage conduit or when water overflows the supply pipes. The float embodies lateral channels which with a counter surface forms an annular groove resting freely against the sealing seat when the float is in the closed position.
