DEVICE FOR TWO-PHASE FLOW ADJUSTMENT AND PORTABLE SPRAYER OF TWO-PHASE FLOW Russian patent published in 2014 - IPC A62C13/66 

FIELD: process engineering.

SUBSTANCE: set of invention relates to two-phase flow regulator and to portable sprayer of two-phase flow designed to spray fie extinguishing fluids. Proposed device comprises mixing chamber (2) composed in case (8) with separate inlet channels for forcing fluid and gas at pressure in and discharge channel (19) communicating mixing chamber with sprayer nozzle by means of flow pipe (20). Note here that a separate cylindrical chamber (1) is arranged in said case (8) to accommodate rotor (3) with blades (5). Rotor blades shut off inlet channels of two phases formed in separate sectors of said chamber (1) confined by rotor blades (5). Gas phase inlet channel (11) is shut off in turn with at least one fluid inlet channel (12) that feed fluid into mixing chamber (2) via open channels between blades. Sector of said chamber (1) including gas inlet channel (11) is also separated from mixing chamber (2) by a continuous section of web (7) that shuts off the channels between the blades of rotor (3) inside said sector.

EFFECT: two-phase flow regulator to be used in portable hand-held fire extinguishers.
