摘要
FIELD: fire-fighting facilities.;SUBSTANCE: invention relates to devices of fire-extinguishing with a charge of fire extinguishing liquid with the ability to spray extinguishing liquid with finely pulverized flow. The devices of fire-extinguishing with finely pulverised flow of fire extinguishing liquid with a given level of dispersion or a flow of foam with a given level of multiplicity, comprises a sealed container with a liquid fire extinguishing agent and compressed expelling gas, a system of release the liquid fire extinguishing agent, a siphon tube, a lock-start gear, and a sprayer. The system of release the liquid fire extinguishing agent is provided with a second siphon tube which through the U-shaped drain is tightly connected to the gas tube, which input end is located above the entry level of the liquid fire extinguishing agent in the sealed container. The sprayer for formation of finely pulverised flow of fire extinguishing liquid comprises a housing and coaxially located in it along the flow the tapered compression chamber and a vacuum chamber. The tapered chamber comprises an outlet. The vacuum chamber comprises an inlet and an outlet. The outlet of the compression chamber is made in the form of a vacuum chamber inlet. The inner surface of the vacuum chamber is made in the form of a surface of revolution which diameter in any of its cross-section exceeds the diameter of cross section of standard straight truncated cone with bases which are formed by the inlet and outlet of the vacuum chamber.;EFFECT: providing opportunity of spraying finely pulverised flow of fire-extinguishing liquid.;15 cl, 3 dwg
