Description

{FIRE EXTINGUISHING DEVICE}

The present invention relates to a fire extinguishing system for extinguishing a flame during a fire in a building, and more particularly to a fire extinguishing system in which a liquid fire extinguishing agent is sprayed after a powder fire extinguishing agent is sprayed.

In general, the powder fire extinguisher opens the pressurized container or the electronically opened valve of the main-pressor by the signal sensed by the fire sensor when the fire occurs, and then opens the select valve and the main valve to emit the powder through the radiating head of the predetermined area .

Powdered fire extinguishing agents are generally used for oil fires and are not electrically conductive, so they are also effective for electric fires. It is also used for surface fires including gas and general fires that are ejected by using the fast fire extinguishing performance. Particularly, in the case of the third type (ABC) powder fire extinguishing agent, it is adaptable to the A class fire due to the dustproof effect of metaphosphoric acid.

In addition, powder fire extinguishing agents are widely used for various objects ranging from small capacity in fixed fire extinguishing facilities to large capacity to be installed in hangars of jumbo jet and inside of the oil refineries of LNG tanks as well as early fire extinguishing facilities due to fast fire extinguishing performance.

On the other hand, a powdered fire extinguishing agent has a fast fire extinguishing performance, but if the fire extinguishment of the powder is unsuccessful, the fire extinguishing agent can return to the state before the fire extinguishment.

In case of using fire extinguishing agent in case of fire, especially in case of enclosed space or underground space, it is difficult to secure visibility due to powdered powder and difficulty breathing. In addition, after fire evacuation, It always has the risk of damage.

On the other hand, liquid fire extinguishing agents have been mainly used as a fire extinguishing agent for fires generated in oil fires, gas fires, and household furniture such as wood and ordinary households.

Such a liquid fire extinguishing agent makes it possible to minimize the secondary damage of the powder fire extinguishing agent.

Although powder and liquid fire extinguishing agents are complementary to each other in this way, liquid fire extinguishing agents through sprinklers are generally applied to general fire extinguishing systems of buildings.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a fire extinguishing agent and a liquid fire extinguishing agent which are capable of evolving a fire or electric fire, And to provide a fire extinguishing system of a building that can reduce the secondary damage of the powder fire extinguishing agent.

According to an aspect of the present invention, there is provided a fire extinguishing system for a building having a plurality of fire ejecting nozzles for ejecting fire extinguishing agents according to a fire detection signal,

The powder extinguishing agent is stored under pressure in a first pass,

A second passage through which the liquid extinguishing agent is stored under pressure,

A first main valve for opening the first cylinder according to the fire detection signal,

A second main valve for opening the second cylinder after all of the first cylinder of powder extinguishing agent is ejected,

And a solenoid valve for selectively connecting the powder extinguishing agent and the liquid extinguishing agent to the spraying nozzle.

In the apparatus of the present invention, the solenoid valve is operated to connect the first passage injection nozzle when the fire detection signal is generated.

Further, in the apparatus of the present invention, the timer is provided with a timer for setting the time at which all of the powder extinguishing agent of the first cylinder is ejected, and the second main valve is opened after the timer is operated for a predetermined time .

The present invention as described above enables a fire extinguishing agent and a liquid fire extinguishing agent to be sequentially sprayed in the event of a fire in a building to evolve oil or electric fire while also evolving general wood fire and reduce the secondary damage of the powder fire extinguishing agent .

1 is a circuit diagram in which a powdered fire extinguishing agent is ejected,
2 is a circuit diagram in which a liquid extinguishing agent is ejected.

The fire extinguishing device of the present invention allows the fire extinguishing agent and the liquid fire extinguishing agent to be sequentially injected in the event of a fire in a building, so that it can evolve a general fire of wood while evolving the oil or electric fire and reduce the secondary damage of the powder fire extinguishing agent .

Referring to FIG. 1 showing an extinguishing device according to an embodiment of the present invention, a plurality of ejection nozzles 40 for ejecting extinguishing agents according to a fire detection signal are provided at indoor or outdoor angles of a building. The injection nozzles 40 are opened by the detection of the fire detection sensor s, and the fire extinguishing agent is ejected.

The fire extinguishing system according to the present invention is characterized in that the powder fire extinguishing agent comprises a first cylinder 10 with a pressure stored thereon, a second cylinder 20 with a liquid extinguishing agent stored under pressure, A second main valve (21) for opening the second cylinder (20) after the powder fire extinguishing agent of the first cylinder (10) is blown out, and a second main valve And a solenoid valve (30) for selectively connecting the medicine and the liquid extinguishing agent to the injection nozzle (40).

The solenoid valve 30 is a two-position solenoid valve operated to connect the first cylinder 10 and the injection nozzle 40 when the fire detection signal is generated.

The second main valve 21 is operated after the timer 12 has been operated for a predetermined time after the timer 12 has been set to the time when all of the powder extinguishing agent in the first cylinder 10 is ejected. So that the second cylinder 20 is opened.

1, when the fire detection sensor s detects the occurrence of a fire, the valve is opened and the fire extinguishing agent can be ejected through the injection nozzle 40. At the same time, the first main valve 11 is operated by opening the first cylinder 10 by the detection of the first syringe s and the powder fire extinguisher is ejected through the first line 13. [

The solenoid valve 30 is operated to connect the first line 13 and the third line 43 so that the powder fire extinguishing agent is injected through the injection nozzle 40 and thus extinguishes primarily.

The second main valve 21 is operated so that the second cylinder 20 is operated after the timer 12 in which the time for spraying the powdered fire extinguishing agent of the first cylinder 10 is set is operated for a predetermined time, Open.

At this time, the solenoid valve 30 is operated to connect the second line 23 and the third line 43 so that the liquid fire extinguishing agent in the second cylinder 20 is injected through the injection nozzle 40, .

Here, when the powdery extinguishing agent of the first cylinder 10 is ejected after the liquid fire extinguishing agent of the second cylinder 20 is ejected, the water remains in the inner wall of the third line 43, . Therefore, in the embodiment of the present invention, the liquid fire extinguishing agent in the second cylinder 20 is ejected after the powder fire extinguishing agent in the first cylinder 10 is ejected.

The present invention as described above enables a fire extinguishing agent and a liquid fire extinguishing agent to be sequentially sprayed in the event of a fire in a building to evolve oil or electric fire while evolving general wood fire and reduce the secondary damage of the powder fire extinguishing agent .
