EXTINGUISHER FOR MOBILE EQUIPMENT FOR EDUCATIONAL COMPLEX TRAINING STANDARDS IN THE FIELD OF CIVIL DEFENCE AND PROTECTION OF EMERGENCY

摘要

The invention relates to a portable fire-fighting installations, in particular fire extinguishers to complete mobile educational complex for training in the field of civil defense and protection of the population from emergency situations. The technical result - more efficient use of the fire-extinguishing liquid to extinguish fires of different classes. This is achieved in that the fire-extinguisher, comprising a container with extinguishing liquid from the container liquid expulsion system comprising a siphon tube, locking-starting device connected to the outlet of the siphon tube, fluid flow restrictor which provides control of the cross-section of the flow channel depending on the fluid pressure in the container, the liquid dispenser is formed as a vortex type of foam generator comprising sprayer which is connected to the housing ejecting nozzles configured as a a diffuser, mounted symmetrically with respect to the nebulizer to the body of the ejecting nozzle, a part located closer to the spray gun, are made, at least three windows for air ejection, and inside the ejecting nozzle through at least three spokes rigidly connected to the housing ejecting nozzle is fixed, made of a mesh or perforated material, a two-phase stream splitter in the form of a truncated cone, the smaller base of which is directed towards the spray gun, and more - in the direction of differential cutoff fuzora, wherein the nozzle body comprises two concentric, interconnected, cylindrical bushings bushings larger diameter and smaller diameter of the sleeve, the inside of the smaller diameter sleeve coaxially located screw rigidly connected to its inner surface, for example press-fitted into it , wherein the outer surface of the screw is a helical groove formed within the screw and the screw-threaded bore and in a sleeve of greater diameter, coaxially located nipple rigidly mounted therein, for example by p ezbovogo compound through the sealing gasket, the inside fitting coaxially formed cylindrical hole passing axially disposed in a diffuser, which is connected to a cylindrical chamber formed by the inner surface of the smaller diameter sleeve and the end surface of the screw.
