A first flow pipe 430 to be coupled, a connection portion 440 having one end coupled to the other end of the first flow pipe 430 and formed to be bent at a lower end, and a second flow pipe 431 coupled to the other end of the connection portion 440 ), and a water spraying unit that is coupled to the other end of the second flow pipe 431 and is separated from the second flow pipe 431 when heat is sensed, and is coupled to the end of the connection unit 440 and sprays liquid to the outside ( 470).

The configuration of the sealing part 420 according to the fourth embodiment is shown in FIGS. 11 and 12 and is the same as the first to third embodiments, so a detailed description thereof will be omitted.

11 and 12, a third flow pipe 432 is formed inside the sealing part 420, the first flow pipe 430, the connection part 440, and the second flow pipe 431.

Although not shown in the drawings, the first flow pipe 430 and the second flow pipe 431 may be formed to be changeable into short or long pipes according to the structure and arrangement of the ceiling 2.

A liquid inflow prevention part 422 is connected to one end of the third flow pipe 432, and the third flow pipe 432 has a constant inner diameter and a third flow pipe 432 so that no liquid is ejected at the end. It includes a holder 433 for supporting the third flow pipe 432 in the inner passage of the.

More specifically, the holder 433 has a fitting portion formed at the end so that one side of the heat-sensitive portion 460 is inserted, and a stepped portion 434 is formed at the coupling portion between the holder 433 and the third flow pipe 432, The heat-sensitive part 460 is fitted to the end of the second flow tube 431 and the holder 433, respectively.

Referring to FIG. 12, the connection part 440 includes a first pipe 441 and a first pipe in which one side is fitted with the other end of the first flow pipe 430 and the second flow pipe 431 is fitted to the other side. A second pipe 442 that is fitted to the lower end of the 441 and extends vertically to the lower end, and a third pipe 443 that is fitted to the lower end of the second pipe 442 to be bent downward, and the third It includes a fourth pipe 445 that is fitted to one side of the three pipe 443 and is formed in parallel with the second flow pipe 431.

At this time, a protrusion 444 facing both sides is formed inside the end of the second flow pipe 431, and when the third flow pipe 432 is advanced, the stepped portion 434 of the holder 433 becomes the second flow pipe. It comes into contact with the protrusion 444 of the 431.

In detail, as shown in FIG. 13, when the heat sensor 460 detects whether a fire has occurred, it is separated from the second flow pipe 431, and as mentioned above, the stepped 434 of the holder 433 is In contact with the protruding portion 444 of the flow tube 431, the liquid is sealed so that the heat-sensitive portion 460 is not ejected to the separated portion.

On the other hand, although not shown in the drawings, the second pipe 442 and the fourth pipe 445 may be formed to be changeable to a short or long pipe according to the structure and arrangement of the ceiling (2).

In addition, the watering part 470 is screwed to the end of the fourth pipe 445 so that the liquid supplied from the water supply device 410 may be sprayed to the outside through the connection part 440.

More specifically, when the heat sensing unit 460 senses heat and is separated to the outside due to the occurrence of a fire, the liquid inflow prevention unit 422 is pushed out by the pressure of the liquid supplied from the water supply device 410, thereby As the sealing part 420 is opened accordingly, the first flow pipe 430, the second flow pipe 431, the third flow pipe 432, the first pipe 441, the second pipe 442, the third pipe Liquid is supplied along the inside of the 443 and the fourth pipe 445,

At this time, the water spraying part 470 is screwed to the end of the fourth pipe 445 and coupled to the top of the liquid spraying part 471 and the liquid spraying part 471 in the form of which the liquid spraying pipe is exposed to lower the sprayed liquid. It consists of a deflector (472) that guides to,

As shown in FIG. 13, when the heat-sensitive part 460 is separated to the outside, the liquid spraying part 471 connects the first flow pipe 430, the second flow pipe 431, the third flow pipe 432 and the connection part 440. The liquid supplied through is sprayed to the outside. The liquid sprayed to the outside is not sprayed upwards while hitting the deflector 472, but is sprayed downward, so that the fire can be effectively extinguished.

In addition, by branching the connection part 440 to the central part of the upper pipe as shown in FIG. 13, the second flow pipe 431 and the water spray part 470 coupled to the heat sensing unit 460 are connected to the fourth pipe 445 to the ceiling ( 2) can be formed so as to be coupled through at the same time, and unlike the first to third embodiments, the open type dry sprinkler head 400 has an effect of minimizing the portion exposed to the outside of the ceiling (2).

According to the present disclosure, water can be evenly sprayed into the fire zone by separating the heat-sensing unit, the sprinkler, and the deflector that sense heat, and additionally, there is an effect of adjusting the length and height of the pipe.

The content of the present disclosure described above is not limited by the above-described embodiments and the accompanying drawings. It will be apparent to those of ordinary skill in the art that various substitutions, modifications and changes are possible within the scope of the technical spirit of the present disclosure.
