FIELD: fire safety. ^ SUBSTANCE: invention relates to automatic fire-fighting plants. A plant for supply of a fire-quenching fluid comprises a body with supply and drencher chambers, separated with a seat, a cover with a booster chamber in it, the main slide, a control slide connected to a drive. The supply chamber is installed inside the drencher one and is additionally connected with the booster chamber by a calibrated opening. The control slide is installed separately from the main slide in the booster chamber cover as capable of closing unloading openings. At the outlet of the drencher chambers there are vortex foam generators fixed, each comprising a vessel, distributing and guiding devices. The body is made in the form of a cylindrical shell with circular stiffening ribs at the edges. At one side there is a foaming solution distributor attached to the body by means of spikes installed along generatrices of a truncated conical surface, which is axisymmetric and axial to a cylindrical shell. The foaming solution distributor has a shape of toroid surface connected with an inlet pipeline. Perpendicularly to the inlet pipeline there is an additional pipeline installed with plugs at both ends. Branches are connected to inner cavities of the pipelines: shortened, medium and long, ending with spray nozzles. Each spray nozzle comprises a body and a nozzle with a cylindrical hole, a diffusor and a gasket. ^ EFFECT: higher efficiency and reliability of operation. ^ 1 cl, 3 dwg |
