DEVICE FOR REGULATING TWO-PHASE FLOW AND PORTABLE SPRAYER OF TWO-PHASE FLOW

摘要

1. A device for controlling a two-phase flow in liquid sprayers, comprising a mixing chamber (2) formed in a housing (8) having separate inlet channels for supplying a liquid phase under pressure and a gas phase pressure and an outlet channel (19) connecting the mixing chamber with a spray nozzle using a flow tube (20), characterized in that a separate cylindrical layout chamber (1) is formed in the housing (8), a rotor (3) with blades (5) is installed inside the layout chamber, the rotor blades of which are periodically close the inlet channels of two phases formed in separate sectors of the aforementioned layout chamber (1), as delimited by the rotor blades (5), in which the inlet channel (11) of the gas phase is closed alternately with at least one inlet channel (12) of the liquid phase supplying the liquid phase to the mixing chamber (2) through open channels between the blades; in which the sector of the layout chamber (1) containing the inlet channel (11) of the gas phase is also separated from the mixing chamber (2) by means of a continuous section of the partition (7), which overlaps the channels between the rotor blades (3) inside this sector. 2. The device according to claim 1, in which the rotor (3) has from 3 to 7 blades (5), and each of the blades (5) has a recessed cavity (6), inclined in the direction of the side wall of the layout chamber (1) and facing the inlet channel (11) of the gas phase. 3. The device according to claim 2, in which the balancing channel (18) is formed in the side wall of the layout chamber (1) at the same height as the cavity (6). 4. The device according to claim 1, in which the rotor (3) is installed between the base (15) of the layout chamber (1), in which
