Document Type and Number:
WIPO Patent Application WO/1987/005133
Kind Code:
A1
Abstract:
A device for automatic dosage of a gas into a liquid comprises a gas pressure regulator (1), a gas flowrate meter (2), a gas flowrate regulator (3), a one-way vacuum restrictor valve and an ejector (5) connected to the main for the gasified liquid as well as a liquid flowrate meter (9) and a control system (39). The gasflow rate regulator (3) and the one-way vacuum restrictor valve are designed as a combined unit, which comprises a sealed chamber (11), two opposite walls of which are constituted by membranes (12, 13), a hollow cylinder (14) located between the membranes and provided on its butt-end with a central opening (17), a bushing (19) mounted in the centre of the membrane (13) and rigidly connected, by its closed butt-end, with an output element (26) of an actuating mechanism (27) of the gas flowrate regulator (3), a needle valve with a seat (21), and a closing member shaped as a rod (21) with a pointed cap (23) at the end.
