The sprinkler head 400 is a component that normally pressurizes the shrinking tube 310 constituting the valve member 300 to cut off the supply of the water for fire fighting and to open the valve member 300 to be.

3, the sprinkler head 400 includes a plunger 410 movably coupled to the housing 100 to press the contraction tube 310 and a plunger 410 coupled to the housing 100, And a glass bulb 430 for supporting the plunger 410 in a state of being embedded in the bulb case 420 and allowing movement of the plunger 410 while being damaged by the heat generated by the fire .

As shown in FIG. 3, the glass bulb 430 supports the plunger 410 and presses the shrink tube 310, as shown in FIG. 4, The fire extinguishing water is supplied to the fine particle spraying nozzle 200 by allowing the piston 320 to move by relaxing the contraction pipe 310 by expanding and breaking due to heat when a fire occurs.

That is, the sprinkler head 400 may be a thermal member widely used in a conventional wet-type fire extinguishing system.

The operation and operation of the wet nozzle unit 33 will now be described.

3, the valve member 300 is connected to the wet digestion line 30b through the adhesive sheet 321 of the piston 320 as the shrinkage tube 310 is compressed and contracted by the sprinkler head 400, And the supply of water for fire fighting and fire extinguishing is cut off.

When the fire occurs, the valve member 300 opens the wet digestion line 30b and the supply port 110 as shown in FIG. 4, and supplies the water for fire prevention to the mistless nozzle 200.

4, the sparkler head 400 releases the pressure of the shrinking tube 320 as the glass bulb 430 is broken due to the heat of the fire and the movement of the plunger 410 is allowed, (320) is spaced at the end of the wet digestion line (30b) while moving by the relaxation of the shrinking tube (320).

The water for fire fighting in the wet digestion line 30b flows through the water hole 322a of the water screen 322 constituting the piston 320 and is supplied to the mist nozzle 200. [

Then, the supplied water is introduced into the upper portion of the nozzle housing 210. At this time, the water for fire fighting is split into two sides by the split pin 242 fixed to the communication ring 241, and flows into the nozzle housing 210 while causing a vortex.

The water is discharged to the orifice 211 while rotating along the outer flow path 220a formed on the outer peripheral surface of the outer tip 221 and is rotated along the inner flow path 220b formed on the outer peripheral surface of the inner tip 223 And is discharged to the central orifice 222a.

At this time, the water for fire extinguishing water discharged to the orifice 211 is dispersed in a fine particle state by colliding with the protruding protrusion 231a of the protruding nipple 231 as shown in FIG. 9, And diffuses into the mist state.

As described above, according to the automatic control and the non-explosion-proof fire extinguishing system using the touch screen according to the present invention, the water for fire fighting or the fire extinguishing water circulates in the water supply line 30 and the bypass line 50 by the low- The fire can be rapidly and smoothly evolved since it is sprayed in a non-split state by the high-pressure pump 60 when a fire occurs.

The operation of the pumps 40 and 60 and the open / close valves 71 is monitored through the touch screen 72 constituting the controller 70, The central control can be smoothly performed and the malfunction of the low pressure pump 40 or the high pressure pump 60 can be verified by monitoring the pressure of the water supply line 20 through the pressure sensor 73. [

Since the tank valve 13 constituting the storage tank 10 supplies water for fire fighting or fire extinguishing liquid to the tank body 11 in accordance with the detection signal of the water level sensor 12, have.

In the case of the wet type 30b, the supply port 110 of the housing 100 may be used in various ways, such as the dry type 30a, the wet type 30b, and the fire hydrant 30c. The valve member 300 shielding the wet digestion line 30b is opened by the sprinkler head 400 and the structure can be simplified through a mechanical mechanism. 310 are contracted or loosened by the sprinkler head 400 to move the piston 320, so that the piston 320 can be controlled in a stable and rigid state with the water for fire fighting or the fire extinguishing liquid.

The water or fire extinguishing water that has flowed into the nozzle housing 210 constituting the wet nozzle unit 33 and the dry nozzle unit 31 of the mist nozzle 200 is blown by the nozzle tip 220 into the orifice 211 And the water or fire extinguishing water discharged to the orifice 211 collides with the protruding protrusions 231a of the protruding nipple 231 and then collides with the recessed portion 232 to be dispersed, So that the evolving power of the fire can be improved.

In addition, when the nozzle tip 220 is constituted only by the outer tip 221, the water for fire fighting or the fire extinguishing agent can be dispersed to both sides of the protruding nipple 231 through the outer passage 220a.

Since the inner tip 223 is coupled to the receiving portion 222 of the outer tip 221 to form the inner flow path 220b and spray water or fire extinguishing liquid through the central orifice 222a, The range can be extended.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various changes, substitutions, and alterations can be made therein without departing from the spirit of the invention.
