The present invention relates to a sprinkler head, and in particular, to reduce the cost by changing the structure of the deflector to make the body and the lower frame in one piece, and reduce the cost by eliminating the coupling holes formed in the lower frame because the body and the lower frame is integral. It is related with the sprinkler head which can do it. In addition, the present invention relates to a sprinkler head capable of preventing malfunction due to foreign matter.

In general, the sprinkler is the upper part of the building, that is, the heat sink of the sprinkler attached to the ceiling or the wall, the fuse is melted by the heat in the event of a fire, the support component falls off, the digestive fluid is radiated by the deflector as the digestive fluid pipe installed on the upper part is opened And extinguishing fluid is radiated from the deflector to the entire ignition point.

The fire extinguishing liquid is sprayed (분무), so it is effective in liquid fire, and it is suitable as a fire extinguishing facility in the part of the underground cavity or difficult to find fire or extinguishing activity, or a lot of underground buildings or combustibles (combustible materials) The scope of application is very wide. It usually operates at 67 ~ 180 ℃, but it depends on the type, and the installation location, layout, and the amount of waterproofing are regulated by fire method according to the type of building and the degree of interior.

The head should be installed 10 ~ 20cm away from the back of the ceiling and placed at a horizontal distance of 2.1m or less (2.3m or less for a fireproof structure). 3.2m living room in apartment (apartment) households 3.2m or less). A similar fire extinguishing facility is a drencher that has a head installed on the roof, at the edge of the eaves, at the edge of a window, and prevents the combustion of adjacent fires with a water film when it is waterproof.

A cross-sectional view of a sprinkler head according to the prior art is shown in FIGS. 1 and 2. As shown, the sprinkler head is formed with a body 1 to which the pipe of the fire extinguishing system is connected, and the frame 2 is screwed to the lower portion of the body 1. A holder 4 is provided inside the frame 2 to block the digestive fluid passage of the body 1, and the holder 4 is supported by the upper and lower couplings 7 and 8. The couplings 7, 8 are connected to the lower heat collector 5 and in the event of a fire, the melting fuse 6 is operated with the spring 9 by recording to couple with the heat collector 5 as shown in FIG. 2. Both rings 7 and 8 are removed so that the holder 4 descends with the deflector 3. As a result, the extinguishing fluid is ejected to extinguish the fire.

The sprinkler head according to the prior art has a problem that the body and the frame is formed of a different body has a large number of parts, complicates the structure and at the same time as the body and the frame is assembled by screw coupling as shown in FIG. A hole for inserting the tool is formed to facilitate the assembly by grasping and rotating the frame. Therefore, there is a problem that more time and money is put into the production.

The present invention has been made to solve the problems of the prior art described above, by forming the body and the frame to be assembled by screwing integrally, there is no need to make a screw hole formed in the frame can reduce the production time and cost The purpose is to provide a sprinkler head.

In the sprinkler head according to the present invention is connected to the pipe of the fire extinguishing equipment, when the fire occurs in the sprinkler head to eject the extinguishing liquid by removing the parts blocking the extinguishing liquid by the heat, the internal passage through which the extinguishing liquid is formed is formed When the passage is extended but the inner wall and the outer wall is formed so as to form a double pipe and the outer wall is extended longer shape, the holder is installed to block the inner wall end of the body so that the digestive fluid is not ejected, and when descending together with the holder It characterized in that it comprises a deflector installed to be caught by the inner jaw formed on the outer wall end of the body.

Here, the head is characterized in that there is no assembly hole for coupling the two parts because the frame is integrally formed in the body.

In addition, the sprinkler is characterized in that composed of two thermal plates.

Since the sprinkler head according to the present invention integrally forms the body and the frame, there is no need to form an assembly hole for joining the two parts, thereby providing an effect of saving manufacturing time and cost.

3 is a front view of a sprinkler head according to the prior art,
4 is a sectional view of the sprinkler head according to the present invention,
5 is a cross-sectional view at the time of operation of the sprinkler head according to the present invention;
6 is a front view at the time of operation of the sprinkler head according to the present invention;
7 is a perspective view of a deflector which is a part of the sprinkler head according to the present invention.

4 to 7, the sprinkler head according to the present invention has a body 10 to which a pipe through which the extinguishing fluid of a fire extinguishing facility passes, and components inside the body 10, and a lower collector as shown in FIGS. 4 to 7. It consists of

The body 10 is formed with an inner passage 11 through which the digestive fluid is moved, and the passage 11 extends to form an inner tube 12 and an outer wall 13 to form a double tube, and the outer wall 13 is extended longer. Has a shape. The holder 40 is installed inside the body 10 to block the inner wall end of the body 10 so that the extinguishing liquid is not ejected. The washer 20 and the seat 21 are installed at the contact portion between the holder 40 and the inner wall 12 of the body 10. When the holder 40 is installed in this way, the digestive fluid cannot pass. A deflector 30 is installed around the holder 40. As shown in FIG. 7, the deflector 30 has a hole 30c formed so that the center holder 40 is fitted into the lower plate 30a having a ring shape, and an inner jaw 13b at the bottom of the body 10 when descending. It consists of a snap ring-shaped support ring 31 of the upper end to be caught on, and three connecting rods 30b connecting the lower plate 30a and the support ring 31 to each other. The support ring 31 has a snap ring shape. In other words, the support ring 31 is made of a ring shape, but is made of a portion cut in shape. Therefore, when the pulled in the incision portion is reduced in diameter, when released, the original position by the elastic force is returned to the original diameter. Referring to FIG. 5, the support ring 31 is hung on the inner jaw 13b of the body 10, and when the ends of the support ring 31 are pulled from each other, the diameter of the support ring 31 is reduced and the separation is possible from the body 10. Of course, the assembly can also be easily assembled using this method. Since such assembly is possible, the conventional body and the lower frame can be formed integrally, not separately.

A stop ring 41 is fitted below the holder 40. A groove is formed in the holder 40 of the portion in the circumferential direction, and a stop ring 41 also formed in a snap ring shape is assembled. When the stop ring 41 is pushed against the groove of the holder 40, the stop ring 41 is opened and is driven into the holder 40 and then assembled to return to its original state. This stop ring 41 prevents the holder 40 from escaping from the deflector 30 when the holder 40 moves upward.

Under the deflector 30 and the holder 40, the upper and lower couplings 51 and 53, the clamping ring 52, the rod screw 50, the locking screw 60, the collector 70, the insulating plate ( 62, a fuse 61 is provided. According to the present invention, two heat transfer plates can be provided.

The lower coupling 53 is formed differently from the conventional one. That is, the upper and lower couplings 51 and 53 are installed at the end of the outer wall 13 of the body 10 to support the holder 40 at the same time, while blocking the end thereof, and the upper coupling 51 is operated. To go down, the lower coupling 53 is formed with a jaw made of a larger diameter outside the outer jaw (13a) formed on the end surface of the body (10). This protects the internal parts and prevents leakage or malfunction even if the couplings 51 and 53 are pushed from the bottom or impact from the outside occurs.

Normally, the holder 40 blocks the digestive fluid passage 11 in a state as shown in FIG. 4, and then the holder 40 and the deflector 30 sit down as shown in FIG. 5. That is, the remaining parts are separated and dropped, and the support ring 31 of the deflector 30 hangs on the inner wall 13b of the body 10, and the extinguishing fluid passes through the inner passage 11 and is widened by the deflector 30. Spreads.
