Description

[0001] Sprinkler head apparatus [0002]

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.
