Estimating the term…
The invention is aimed at generating a finely dispersed gas-and-drop flow with its cross-section in the shape of an ellipse and uniform intensity distribution. A fluid spray nozzle is built in the form of a body (1) with two coaxial channels (2) of the same cross-section designed for head liquid supply and a nozzle having a shape of a conical diffuser (3). The diffuser (3) is oriented transverse to the channels, the area of its inlet orifice not exceeding the total cross-section area of the channels. The fire extinguisher fitted with a fluid spray nozzle comprises a liquid vessel (4) for fire extinguishing, a liquid expulsion system, a pipeline (11), connecting a liquid cavity (5) of the vessel (4) to a spray nozzle and at least one valve or a regulator (8) to control the liquid supply to the spray nozzle.
A fluid spray nozzle made in the form of a body (1) with two co-axial channels (2) of the same cross-section designed for head liquid supply and a nozzle, an inlet orifice of which is formed by intersection of internal channel surfaces and a nozzle-forming surface, wherein the nozzle is formed as a conical diffuser (3) with an angle at the diffuser-forming cone vertex oriented transverse to the channels (2), the diffuser (3) inlet orifice area not exceeding a total cross-section area of the channels (2).
