In the third embodiment, the valve is provided with a valve with a seat and a retainer, wherein the valve, the housing and the plug form an insulated volume with which the actuator is connected via a hole in the housing. The latch can be made in the form of a spring.

FIG. 1-3 schematically shows a high-speed shutter, options.

The gate capacitance 1 of FIG. 1 is filled with a fire extinguishing fluid under pressure from a gas, such as nitrogen. The body 2 of the shutter is rigidly connected to the container 1. A destructible plug 3, which is made in the form of a membrane having a weakened annular cross-section at the periphery, seals the outlet cross section of the shutter. On the housing 2, a camera with a pyrotechnical device 4 is installed. The insulated volume 5 of the shutter is connected to the camera of the pirobozhitel 4 by opening 6 and is separated from the tank 1 by a partition 7. The housing 2 has a stop 8 for the partition 7. Clamp 9 made in the form of a rod It is in contact with the partition 7 and the breakable plug 3. The membrane 10 separates the igniter 4 from the fire extinguishing fluid. A spray nozzle 11 is rigidly connected to the housing 2 with openings for liquid outlet.

In accordance with FIG. 2 tank 1 is filled with extinguishing fluid under pressure of gas. The body 2 of the shutter is rigidly connected to the container 1, the breakable plug 3, made in the form of a membrane having a weakened section at the periphery, seals the output section of the shutter. A housing with a pipper A is installed on housing 2. The gate volume 5 is separated from container 1 by means of an additional plug 12, which is rigidly connected to housing 2, supported by support 13. The plug 12 to compensate for thermal expansion of the liquid has a choke hole 14 section 15 and installed with a gap relative to the stop 8. Cap 1 can break down over section 15 at a pressure less than the pressure of the extinguishing fluid, and the inner diameter of the stop 8 is smaller than the small diameter of section 15. Isolated around The port 5 communicates with the chamber of the pyroboiler 4 through the opening 6 in which the membrane 10 is installed. With the housing 2, the atomizer 11 is rigidly connected to the openings for the outlet of the liquid.

The gate capacitance 1 of FIG. 3 is filled with a fire extinguishing fluid under gas pressure. The body 2 of the shutter is rigidly connected to the container 1. A destructible plug 3, which is made in the form of a membrane having a weakened section along the periphery, seals the output section of the shutter. On the housing 2 is installed a camera with a piperator 4. The volume of the shutter 5 is separated about

tank 1 through the lever 16 mounted on the axis 17, which for fixing the lever 16 in the closed position on the saddle 18 is made in the form of a torsion. The insulated volume 5 communicates with the chamber of pyrobudger 4 through apertures 6, in which a membrane 10 is installed. A sprayer 11 is rigidly connected to the housing 2 with openings for liquid outlet.

ten

The operation of the shutter in the first embodiment is as follows.

When applying electric signal

The experiments are initiated by the trigger 4. Under the action of the combustion products, the membrane 10 is destroyed, and the gases through the opening 6 enter the isolated volume 5, affecting

liquid. At the same time, as a result of a sharp increase in the pressure of the liquid, the partition 7 sits on the support 8, preventing the transfer of pressure by the hydro shock wave front into the tank 1, and

plug 3 is destroyed over the weakened section, opening the flow area of the shutter. After that, the fire extinguishing fluid ejects the partition 7 into the spray gun 11 and through the holes of the splitter 11 enters the protected area.

According to the second variant, when the pyrobudget 4 is triggered, the gases, destroying the membrane 10, enter the isolated volume 5. With this, the excess

fluid pressure leads to the destruction of the additional plug 12, which sits on the support 8, and plug 3, over the weakened section. After that, the plug 12 falls into the spray gun 11, and the extinguishing fluid enters the protected area.

The shutter of the third option works as follows.

When pyrobudger 4 is triggered, the gases destroy the membrane 10 and enter the isolated volume 5. The excessive pressure of the liquid leads to the destruction of the plug 3, after which the lever 16 opens, twisting the axis 17, made in the form of a torsion, and the extinguishing fluid enters the protected zone. After exiting the fluid, the lever 16 closes.
