Description

[0001] The present invention relates to a sprinkler head,

The present invention relates to a sprinkler head device capable of height-adjustable corresponding to the height of a ceiling.

Generally, with the advantage of initial digestion, high-rise buildings, high-rise apartments, theaters, and department stores are required to install sprinklers by fire brigade. The basic requirements for such sprinklers are specified in KSBISO 6182-1 to KSBISO 6182-1.

The sprinklers are classified into various types according to the shape of the heat insulating body, the shape of water distribution, the installation position, the sensitivity characteristic and the special use. Basically, a heat sensing body for sensing heat is assembled and the heat sensing body is automatically operated at a predetermined temperature Thereby opening the orifice so that it is designed to automatically emit a specified amount of water and a spray pattern embodied throughout the design area.

In addition, the sprinkler is constructed such that the sprinkler head is connected to the water supply pipe through a pipe fitting. Since the height of the space formed on the ceiling is different for each structure, the length should be designed to be adjustable in the upward and downward directions.

However, in the conventional sprinkler head device, the inner barrel has to be inserted from the upper side to the lower side of the outer barrel in order to screw the outer barrel and the inner barrel. For this purpose, the lower outer diameter of the inner barrel is formed smaller than the inner diameter of the outer barrel . In addition, since a stop ring for stopping the upward movement of the outer barrel must be fitted to the lower portion of the inner barrel, it is inevitable to form a groove in the lower outer diameter of the inner barrel. In order to move the inner barrel up and down, It is necessary to cut out a part of the lower outer diameter because it is necessary to make the tool fastening portion into a polygonal shape on the lower side outer diameter.

Accordingly, since the lower portion of the inner barrel, which is made to have a mechanical structure and a thickness that is hard to withstand the physical assembly pressure, becomes thinner due to the engagement of the sprinkler head, the inner barrel is damaged In addition, there was a problem that the binding site pops up due to the strong pressure of the fire water.

Here, the inner barrel is made thin in thickness because the outer barrel used in the fire extinguishing system, the sprinkler head, etc. are standard screws, so that the inner diameter of the inner barrel can not be made to an arbitrary size. When replacing the sprinkler head according to the occurrence of defects, the sprinkler head is separated from the inner barrel, the outer barrel is separated from the water supply pipe, the detent ring fitted to the inner barrel is peeled off, It is necessary to perform a series of operations to release the engagement between the outer barrel and the inner barrel.

The horizontal pipe is connected to the fire water pipe to introduce the fire water, and then the water pipe is connected to the vertical pipe through the vertical pipe in the downward direction .

The upper end of the connection pipe 30 is inserted into the vertical pipe of the distribution pipe 10 by a predetermined length. The inner wall of the distribution pipe 10 and the outer wall of the connection pipe 30 are sealed by the O-rings 50 as described above.

Therefore, the fire water of the distribution pipe 10 is supplied to the connection pipe 30 by the pressure, and the pressure is constantly maintained in the sprinkler head 60.

3, an outer thread 10a is provided to a predetermined height from the lower end of the distribution pipe 10 in the same manner as the connection pipe 30. As shown in FIG.

Referring to FIG. 3, the outer thread 10a of the distribution pipe 10 is engaged with the second threaded portion 20a of the height adjusting nut 20 so that the height thereof can be adjusted.

1 to 3, the height adjusting nut 20 includes a first screw portion 20c engaged with an outer screw 32 of the connection pipe 30 and a second screw portion 20c engaged with an outer screw And a second screw portion 20a engaged with the first screw portion 10a. That is, the height adjusting nut 20 can be screwed into both the connection pipe 30 and the distribution pipe 10 so that the height of the sprinkler head 60 can be adjusted.

3, the outer diameter of the first screw portion 20c is smaller than the outer diameter of the second screw portion 20a. The inner diameter of the first screw portion 20c is smaller than the inner diameter of the second screw portion 20a.

Referring to FIGS. 2 and 3, the height adjusting nut 20 has a horizontal groove 20b formed horizontally in the outer diameter of the first screw portion 20c, and a portion thereof is cut so as to have a through hole. The grip ring 40 as the nut fixing means is inserted into the horizontal groove 20b to prevent the height adjusting nut 20 from being rotated to fix the installation height of the sprinkler head 60. [

The grip ring 40, which is a nut fixing means, prevents the rotation of the height adjusting nut 20 and fixes the height of the coupling tube 30. [

The grip ring 40 is inserted into the horizontal groove 20b formed in the height adjusting nut 20 so as to restrain the outer surface screw 32 of the connection pipe 30, Is inserted into the outer surface screw (32) of the pipe (30) and restrained.

2, the grip ring 40 includes an inlet portion 40b that is opened and cut at one end and a mouth portion 40b that is extended from the inlet portion 40b to have a width greater than that of the inlet portion 40b, And a restricting portion 40a which penetrates through the through hole and restrains the outer surface screw 32 of the connection pipe 30. [

The grip ring 40 has a flat plate shape and has a partially incised portion such that the inlet portion 40b and the restricting portion 40a are provided.

The width of the inlet portion 40b of the grip ring 40 is formed to be slightly smaller than the width of the restricting portion 40a so that when the insertion portion 40b is inserted into the horizontal groove 20b, And after the insertion, the inlet portion 40b must be forced to expand again so that it can be prevented from being separated.

Part of the restricting portion 40a passes through the through hole formed in the horizontal groove 20b, that is, passes through the body of the height adjusting nut 20, . Therefore, the height adjustment nut 20 can not be rotated further, and the height of the connection pipe 30 can no longer be adjusted, so that the height of the sprinkler head 60 is fixed.

Referring to FIG. 3, the assembly of the sprinkler head device will be described below.
