The first valve 130 and the second valve 150 may be configured to be closed.

Next, the compressed air container 120 is connected to supply high pressure compressed air. For example, high-pressure air or nitrogen gas, or any gas flow that helps the extinguishing effect may be used, and may be applied by increasing the number of containers according to the amount of discharged air required. It is also possible to use an air compressor.

Supply. In more detail, the foam aqueous solution passes through the air injection holder 160 along the foam aqueous solution supply line 140. At this time, the flow rate of the foam aqueous solution is adjusted by passing through the inlet side of the air injection holder 160, and the compressed air bubble generated by injecting compressed air into the adjusted foam aqueous solution is supplied to the injection device 300. Here, the injection device 300 is a device that is installed in a place to prevent fire to inject the foam aqueous solution to the outside. The injection device 300 should be a type of injection hole in which the generated compressed air bubbles are delivered without abnormality in the supply line and can be injected as it is without installing any device for adjusting the flow rate and other additional devices in the injection device 300. . Such a dedicated injection hole should be used as a rotary injection hole.

Next, the second valve 150 is installed at the rear end of the foam aqueous solution storage container 110 in the foam aqueous solution supply line 140, and opens and closes the discharge of the foam aqueous solution. At this time, in order to maintain a constant discharge pressure may be additionally installed a constant pressure valve 180 to supply a constant foam solution at a pressure of 3kg / Cm 2 or more.

On the other hand, the first valve 130 and the second valve 150 may be made of a valve operated by electricity, such as a solenoid valve, or a valve operated by pneumatic pressure controlled by the solenoid valve. For this reason, the first valve 130 and the second valve 150 may be configured to operate in conjunction with an electrical signal such as a fire detector.

And when the second valve 150 is opened, the compressed air discharged from the compressed air container 120 is supplied to the foam aqueous solution storage container (110). Thereafter, the pressure in the foam aqueous solution storage container 110 is increased, and the foam aqueous solution is supplied to the injector 300 through the air injection holder 160 along the foam aqueous solution supply line 140. In this case, the air injection holder 160 may allow the air to be quickly mixed with the foam aqueous solution supplied along the foam aqueous solution supply line 140 by the compressed air supplied through the air injection nozzle 162.

As a result, the smart powerless automatic fire extinguishing system 100 according to the present invention can provide an excellent fire extinguishing effect while reducing the amount of digestion water and the stock solution. In particular, the compressed air bubbles generated by passing through the air injection holder 160 is preferably formed in a structure that does not interfere with the passage through the injection port to reach the flower source.

At this time, the compressed air is a type that secures the surface area of the moisture, and uses the heat of vaporization to cool, and can be formed to suppress the fire by widening the fire extinguishing area by inducing a decrease in surface tension when launched in the direction of the combustion products.

In addition, since the foam aqueous solution and the compressed air generally have to be mixed at a constant ratio (1: 4 to 1: 7) to have a large extinguishing effect, the foam aqueous solution and the air are injected into the air injection holder 160 at such a constant ratio, so that the foam aqueous solution and air are correct. It is desirable to allow the compressed air bubbles produced by the mixing to be released.

In addition, by using compressed air to supply the foam aqueous solution, a separate power source such as a pump is not required. Thus, the initial investment cost is reduced when the system is constructed, and when the package is configured, the size is small so that it can be stored in an independent dangerous storage space or a small space. Easy to install, you can expect the perfect fire extinguishing effect.
