Description

The invention relates to fire fighting equipment, and specifically to portable fire extinguishers, and can be used to extinguish fires in small isolated rooms (for example, ships) using the method of volumetric-chemical extinguishing and separate open fires in open areas using liquid evaporative fire extinguishers. - tely, for example freon 1211, 1301 2402, etc.

The purpose of the invention is the expansion of the operational and tactical capabilities of the fire extinguisher being dropped.

FIG. 1 shows a fire extinguisher, a longitudinal section J in FIG. 2, a directional spray device connected to a conical stopper placed in the outlet of the fire extinguisher,

The fire extinguisher consists of a housing 1 Sch1LIiScht form with an inlet 2 and an outlet 3 nozzles, inside the case there is a free piston A with o-rings in the grooves 5, In the inlet nozzle 2 by means of o-rings 6 and a threaded figured sleeve 7, the membrane 8, made of metal foil. In the sleeve 7 a needle 9 is fixed to the floor and an O-ring 10, which includes the neck of the cartridge 11 with a gas propellant. The balloon is blocked by a fusible plug 12 (like a household siphon), the balloon is placed in the housing 13 ,. having a possibility to screw onto the nipple 2, B of the upper part of the fire extinguisher, the atomizer 14 is directed to the action of the movable fastener; To the outlet nipple 3 the valve 15 is fixed, inside which the ball valves 16 and the grids 17 are freely located, preventing the valves 16 from falling into the nipple 3, Perforated pipes 1-18 are attached to distributor 15 for dissipative spraying of fire extinguisher 19 poured into the case. To protect against external damage, elastic coils are fixed to perforated tubes 18. 20, outlet conduit 3 matingly cap nut 21 is fixed conical floor plug 2 having radial holes 23 by the number of side holes in the pipe

which are connected by a distributor 1 with perforated tubes. On the tapered stopper 22, a spray gun 14 of a directional action, rigidly connected with it, is placed; the spray gun and the tip 24 with a locking spring-loaded spring 25 and needle 26 and the handle 27 with a trigger mechanism 2 controlling the locking needle 26. When a hawk of sealing rings 29 in the nozzle is fixed membrane 31, sealing the cavity of the fire extinguisher. The conical floor of the plug has the ability to rotate in two fixed positions. In the first position, the radial channels 23 in the tube coincide with the corresponding radial channels of the outlet nozzle, in the second position the radial channels in the hollow conical plug and in the outlet nozzle are sealed off, the floor of the conical piercing through the longitudinal channel is connected to the cavity of the body of the dispenser of directional action; the needle is controlled by a trigger 8 fixed on the handle 27,

The fire extinguisher works as follows ..

Variant of the fire extinguisher. By the handle 27, the body of the atomizer 14 and the hollow conical plug 22 are placed in a position in which the primary channels in the plug 22 coincide with the radial channel of the outlet nozzle 3. The case 13 is screwed onto the inlet nozzle 2, while the low-melting plug 12 is stuck into the hollow needle 9 and breaks through it, the fire extinguisher is thrown into the fire.

The compressed gas from the cartridge enters the axial orifice of the needle 9 and, breaking the membrane 8, enters the piston 4 and begins to compress the igniter 19 until the membrane 31 breaks (Fig 2), after which the piston begins to force the fire extinguisher through the hollow radial channels conical plug 22 and outlet nozzle 3 into perforated tubes 18. As a result, the dehumidifier is dispersed. It accumulates ai: with spherical flows, regardless of the position of the fire, in the fire center, which ensures the most efficient extinguishing of the fire.

Option manual fire extinguisher. With the handle 27, the body of the atomizer 14 and the hollow conical plug 22 are placed in a position in which the radial channels in the outlet nozzle 3 are tightly closed. The further work of the fire extinguisher is carried out as in the abandoned version until the moment of immediate extinguishing of the fire source.

The directional guiding device presses the trigger 28, while the needle 26 opens the hole in the tip 24 and the fire extinguisher is forced through the piston out of the fire extinguisher body in the form of a directional flow. Holding the fire extinguisher by the handle 27 and the body 13, the fire extinguisher is directed to the flame. If necessary, by releasing the trigger 28 and pressing it, you can interrupt the extinguishing process and resume it.
