Abstract

The invention relates to a fire extinguishing technique and makes it possible to increase the efficiency of the fire extinguishing system by allowing it to be controlled. The extinguishing fire extinguished through the nozzle 7, interacts with the plate 8 and gives an audible signal that the fire extinguishing system was turned on. When the extinguishing agent has been consumed, the buzzer stops. This indicates the end of the system. 1 il. (L oo oo with 00 O5 Go

Description

The invention relates to a fire extinguishing technique and is an improvement of the known invention according to the authors. St. No. 1093349.

The purpose of the invention is to increase the efficiency of the fire extinguishing system by ensuring its control.

The drawing shows the proposed device, obsh, i view.

The device contains a sprayer 2 connected to the fire extinguishing system 1 and filled with fire Besh, having a housing 3 with spring-loaded stoppers 4, nopineHb 5 with aperture 6, a device for giving a signal to turn the fire extinguishing system on and off in the form of a nozzle mounted inside 7, a plate 8 placed in the piston 5. In this case, the nozzle 7 is in communication with a hole 6 of the piston 5 having lower 9 and upper 10 cavities for stoppers 4, a spring 11, cooperating with an upper end with an emphasis 12 fixed on the inner side bushings 13, made of heat-shrinkable material and a spring 11, which grips the upper end through the stop 12 and the atomizer 2, and interacting with the lower end with the outer end of the piston 5.

The device works as follows.

In the non-working state, the stoppers 4 fix the piston 5 with the opening 6 in the upper position, with the result that the opening of the atomizer 2 is closed. In the event of a fire under the action of high temperature, the sleeve 13 begins to decrease in diameter and, through the stop 12, compresses the spring 11 to its final position, after which the spring 11 works as a rigid element. After the compression force has reached a higher rated value, the stoppers 4 are actuated, as a result of which the piston 5 is sharply displaced downwards under the action of potential

energy of the spring 11. At the same time, the opening 6 of the piston 5 is aligned with the opening of the sprayer 2, the stoppers 4, interacting with the upper recesses 10 of the piston 5, fixing the piston 5 in the lower (operating) position, keeping it from dislodging with the possible combustion of the sleeve 13 during a fire.

At the same time, the extinguishing agent extinguished through the nozzle 7, interacts with the plate 8 and gives an audible signal that the fire suppression system is activated. After the extinguishing of the extinguishing agent has elapsed, the audible signal ceases, indicating that the system has stopped working.

Transverse shrinkage of the sleeve 13 ensures reliable operation of the valve of the fire extinguishing system trigger mechanism in the event of a fire. The automatic fixing of the piston 5 in the working position ensures the operation of the fire extinguishing system even when the start mechanism 13 is burned, and the rapid alignment of the holes of the piston 5 and the spray gun 2 ensures that the fire extinguishing system is reliably turned on and the system quickly reaches its full capacity.
