FIELD: fire-fighting facilities.SUBSTANCE: invention is intended for fire extinguishing with automatic fixed installations. The fire-extinguishing module comprises a housing, a cylinder with a siphon tube, a pressure signal indicator. The cylinder is filled with a fire-extinguishing liquid, at the outlet of the cylinder a lock and release pyrotechnic device is mounted. The pressure signal indicator is mounted on upper part of the cylinder. The sprayer comprises a foam nozzle and a distributor of two-phase flow. The nozzle housing is made in the form of a cylindrical shell, on which the windows are made for ejecting air. At the output of the housing the distributor of two-phase flow is fixed which is made in the form of a packet of serially connected networks. The packet of networks is formed by two conical surfaces with a common circular base which is fixed on the housing. The conical surface which faces the cut of the cylindrical shell is formed truncated. The nozzle housing is attached to the conical surface of the diffuser, on which the windows for ejecting air are located. The sprayer consists of a sleeve, on which one side there is a partition. The vortex chamber is fixed coaxially on the inner surface of the sleeve of the sprayer, and is made in the form of a cylindrical cavity with tangential holes. The cylindrical cavity is formed by a ring and two partitions, one of which is made solid, and the other - with the outlet opening.EFFECT: increased operating speed.2 dwg |
