Sprinklers {Fire sprinklers}

More particularly, the present invention relates to a fire-extinguishing sprinkler, and more particularly, to a fire-extinguishing sprinkler, and more particularly, to a fire-extinguishing sprinkler which comprises a sprinkler head coupled to a pipeline, It is about the fingers.

In general, Spinkler Systems is a fire extinguishing system that detects the fire in a generation and automatically suppresses the spread of the fire by spraying water to suppress the fire early. Especially, In the case of high-rise buildings, the need for them has become even higher. Recently, sprinkler systems have been installed in most high-rise buildings.

1 and 2, the conventional sprinkler system includes a pipe 10 installed in a ceiling and supplied with digested water, a coupler 40 which is an elbow pipe connected to the pipe 10, a coupler 40 And a sprinkler head 200 connected to the sprinkler head 200.

The sprinkler head 20 is installed so as to protrude from a ceiling finishing material (not shown) for finishing the ceiling.

2, the sprinkler head 20 includes a hollow main body 21 which is screwed with the coupler 40 and through which the digestive water flows through the pipe 10, And is lowered to the lower end side of the frame 22 in the event of a fire so as to be introduced into the main body 21 And a deflector 23 for radiating the extinguished water in a radial direction.

At this time, a step 22a protruding inward is formed at the lower end of the frame 22 so that the deflector 23 can be lowered. A hollow main body 21 is provided at the center of the deflector 23 An opening / closing block 24 is formed to protrude toward the main body 21 to prevent leakage of the extinguished water.

A fixing part 25 and a thermosensitive part 26 are sequentially installed below the deflector 23. The fixing part 25 includes two fixing plates 25a stacked vertically, A sealing member 25b for fixing the fixing portion 25 to the frame 22 is provided on the outer side surface between the fixing plates 25a so as to be in contact with the inner side surface of the step 22a of the frame 22, A plurality of heat-insulating plates 26a are vertically stacked and fixed to the stationary part 25. As shown in FIG.

The sealing member 25b of the sprinkler head 20 installed as described above is a member which is melted by heat when a fire occurs and the sealing member 25b is caught by the sealing member 252 at the step 221 of the frame 22 when the sealing member 252 melts The fixing part 25 is separated from the step 22a of the frame 22 so that the fixing part 25 and the thermosensitive part 26 are separated from the sprinkler head 20 and the deflector 23, Is lowered by the water pressure of the extinguishing water flowing into the main body 21 and caught by the step 22a of the frame 22 so that the extinguishing water is radially injected and discharged.

Meanwhile, in the sprinkler system, sufficient fire can be performed only when the fire extinguishing water is filled at a predetermined pressure or more for rapid fire suppression. Therefore, when the sprinkler system is installed, the pressure of the fire extinguishing water is checked in the pipe 10 The process is essential.

1, the cap 1 is screwed into the end of the coupler 40 instead of the sprinkler head 20 after the piping 10 is installed to prevent water leakage. In this case, The digestion water is filled in the pipe 10 and the pressure of the water is checked to confirm the water pressure. After confirming the water pressure, the stopper 1 is taken out from the pipe 10 to prevent frost, and the digestion water filled in the pipe 10 is completely discharged The sprinkler head 20 is attached to the sprinkler head 20. Such a water pressure test is inconvenient and cumbersome due to a lot of work processes proceeding with the coupling of the plug 1 and the separation of the plug 1, There were disadvantages.

When the water pressure test is performed in a state where the sprinkler head 20 is engaged in place of the cap 1 in the hydraulic test, the workability is better than in the case described above. However, when the sprinkler head 20 installed after the water pressure test is separated from the pipe 10 The digestion water filled in the pipe 10 is frozen in winter, and the pipe 10 is finally broken. Therefore, even when the sprinkler head 20 is used, the sprinkler head 20 must be separated from the piping 10 after the water pressure test to completely discharge the water. In this case, however, There is a problem in that the disadvantages as in the case are retained.

The deflector 230 is extended from the deflector 230 to open and close the hollow main body 210, A fixing part 250 fixed to the step 221 of the frame 220 to support the opening and closing block 240 and a plurality of heat shielding plates 261 under the fixing part 250. [ But the detailed description thereof will be omitted from the prior art.

In the opening / closing block 240 protruding into the main body 210, a flow path 241 through which water in the main body 210 can flow is perforated in a lateral direction perpendicular to the axial direction of the opening / closing block 240 .

The sprinkler head 200 is formed with a drain member 270. The drain member 270 includes a flow passage 273 formed along the axial direction and a drain hole 272 communicated with the flow passage 273 in a vertical direction And a head portion 275 formed at an upper end portion of the shaft portion 271 and having a larger diameter than an outer diameter of the shaft portion 271. The shaft portion 271 has a cylindrical portion 271,

The shaft portion 271 of the drain member 270 is rotatably installed to pass through the thermal heater 260 and the fixing portion 250 and the opening and closing block 240. The drain hole 272 of the shaft portion 271, The flow path 273 of the shaft portion 271 is selectively communicated with the flow path 241 of the opening and closing block 240 according to the position of the drain port 272, .

Accordingly, when the flow path 273 of the shaft portion 271 communicates with the flow path 241 of the opening / closing block 240 through the drain port 272, the sprinkler head 200 and the digestion The water is discharged to the outside.

Although the flow path 241 of the opening and closing block 240 is shown as being spaced upward from the inner bottom surface of the main body 210 in the figure of the present invention, It is preferable that the flow path 241 of the opening and closing block 240 is located on the inner bottom surface of the main body 210 so that the extinguished water after the water pressure test can be completely discharged.

Particularly, when the digestion water is supplied to the drain member 270 as described above, arbitrary rotation of the drain member 270 can be prevented unless the tool is used by the water pressure of the digestion water.

In addition, a display portion is formed on the outer surface of the shaft portion 271 protruding downward from the sprinkler head 200 by painting or coating so that the position of the drain hole 272 of the shaft portion 271 can be visually confirmed easily desirable.

The head portion 275 of the drain member 270 is seated on the upper surface of the openable and closable member 240 located inside the main body 210 to prevent any disengagement of the drain member 270.

A water pressure test can be performed in a state where the sprinkler head 200 is coupled to the piping 100 by the drain member 270 configured as described above. First, a tool or the like is coupled to the coupling portion 274 of the drain member 270 Thereby rotating the drain member 270 by 90 degrees.

The drain hole 272 formed in the shaft portion 271 of the drain member 270 is spaced apart from the flow passage 241 of the opening and closing block 240 by 90 degrees and thus the flow passage 273 of the shaft portion 271 and the opening / So that the flow path 241 of the valve body 240 is shut off from each other.

In this state, the fire extinguishing water is supplied to the pipe 100 and the pressure is increased to check the water pressure. After confirming the water pressure, the drain member 270 is reversed by 90 degrees in the above-described reverse direction and then raised.

The drain port 272 of the shaft portion 271 coincides with the flow path 241 of the opening and closing block 240 so that the flow path 273 of the shaft portion 271 and the flow path 241 of the opening and closing block 240 are mutually communicated, All the digested water filled in the drainage unit 100 is discharged to the outside, and after discharging the digested water, the drainage member 270 is again lowered and rotated 90 degrees.

As described above, the sprinkler head 200 equipped with the drain member 270 of the present invention is configured such that when the fire occurs, the sealing member 252 is melted by heat, and the sealing member 252 melts the step 221 of the frame 220, The fixing part 250 engaged with the frame 220 is detached from the step 221 of the frame 220 so that the fixing part 250 and the thermosensitive part 260 are separated from the sprinkler head 200 and the deflector 230 and the opening and closing block 240 are lowered by the water pressure of the extinguishing water flowing into the body 210 and the lowered deflector 230 is caught by the step 221 of the frame 220, And discharged.

The drainage member 270 coupled to the opening and closing block 240 is lowered as in the opening and closing block 240. At this time, the flow passage 273 of the drainage member 270 and the flow passage 241 of the opening and closing block 240 It is blocked.
