Abstract

PURPOSE: A linear rod-shaped support stand is provided to prevent water leakage and malfunction of a sprinkler and to rapidly sense heat. CONSTITUTION: A sprinkler head comprises a frame, a water-jet valve(230), a fuse, and a sealing membrane(210). The frame is combined with a water discharge path. A water reflector is combined with the end of the frame. The fuse is formed in a linear type. The linear rod-shaped support stand comprises a rod made of a thermal conductor, a tube made of a thermal conductor, a support stand, and a molten material. The sealing membrane is supported by the fuse and blocks a water outlet of the water discharge path.

Description

Stick type straight support

The present invention relates to the fuse blink of the sprinkler head to form a fuse made of a rod-shaped straight support made of a tube and a rod made of molten material and a heat conductor, so that the leak and malfunction of the sprinkler does not occur and the thermal response is quickly and accurately. The fuse is made of a material similar to the head body to prevent malfunction due to thermal expansion shrinkage for a long time.

 Sprinklers are obliged to be installed on certain buildings or high-rise buildings for the initial suppression of fires. Various kinds of sprinkler installations are used according to the purpose and purpose of use, but the sprinkler has always been accompanied by problems such as ceiling height limitation and malfunction.

1 is a cross-sectional view of a fuse type sprinkler head using a conventional molten metal. The sprinkler head of FIG. 1 cuts off the feed water supplied from the nozzle unit 100 connected to the water supply pipe, opens the feed water by leaving the sealing membrane 110, and operates by hitting the dispersion plate 130 while scattering the feed water. That's the way.

The conventional sprinkler head has a nozzle unit 100 connected to the water supply pipe, a sealing film 110 for blocking the supply water, a dispersion plate 130 for scattering the supply water, a support 121 for supporting it, a support membrane for the sealing film It consists of a heated soluble metal 124 installed in conjunction with several levers 120, 121, 123, 125 to keep in close contact.

When the sprinkler is configured as described above, when the fire temperature rises above the set temperature, the molten metal 124 is melted, and the balance between the levers 120, 121, 123, and 125 supporting the sealing membrane is broken, thereby separating the sealing membrane 110. Digestion water works by scattering the plates.

This sprinkler head has a disadvantage in that the production of the lever is not easy due to the complicated structure of the lever, and when a long time passes, the lever is pushed into the molten metal by the pressure of hydraulic pressure and thus the seal membrane cannot be completely adhered to and leaks.

The present sprinkler head object is to provide a sprinkler head comprising a fuse made of a rod-shaped straight support using a tube and a rod and a support having a protrusion using a heat conductor.

An object of the present invention is made of a straight support and a molten material using a tube and a rod using a heat conductor, and usually supports the hydraulic pressure by a support having a rod and a protrusion using a heat conductor, and when the temperature rises above a certain temperature, the support melts. It works by tilting the rod with the thermal conductor down.

The fuse link of the sprinkler head consists of a flat support and a molten material using a tube and a rod using a heat conductor, and usually supports the hydraulic pressure by a support with a rod and a protrusion using a heat conductor. Since the support rod is tilted and the rod using the thermal conductor is set down, the rod and the support rod with the protrusion support the hydraulic pressure, so that no problem of leakage occurs even at a very high hydraulic pressure, and the structure is simpler than the conventional sprinkler head. In addition, by using a material similar to the sprinkler head body, there is an advantage of preventing malfunction due to thermal expansion and contraction, and also improving work efficiency in production.

The terms and words used in this specification and claims should not be construed as limiting their ordinary or dictionary meanings, and in light of the principle that the concept of terminology may be appropriately defined in order to best explain the invention. It should be interpreted as meanings and concepts consistent with the technical idea of the present invention.

 Therefore, the configuration of the embodiments and drawings described herein are only one of the most preferred embodiments of the present invention and do not represent all of the technical principles of the present invention, various equivalents that may be substituted for them at the time of the present application It should be understood that there may be variations and examples. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  2A is a cross-sectional view of a sprinkler head according to an embodiment of the present invention, the sprinkler head 201 is a frame 202 coupled to the waterproof passage 200, a water jet plate 230 coupled to the end of the frame 202, water injection Fuse 220 supported by the central height adjustment means 240 of the plate 230, a sealing film supported by the fuse 220 and blocking the waterproof opening 201 of the waterproof passage 200

And 210.

 Frame 240 according to an embodiment of the present invention is coupled to the waterproof passage 200, the water reflector 230 is coupled to the end of the frame 250. The waterproof port 201 through which the extinguishing water of the frame 250 connected to the waterproof path 200 is discharged is blocked by the sealing membrane 210, and the fuse 220 is positioned between the sealing membrane 210 and the water jet plate 230. The fuse 220 is fixed by the height adjusting means 240 at the center of the water jet plate 230.

 Therefore, it is considered that it is preferable to use a screw for the height adjusting means 240, the fuse 220 is raised by tightening the height adjusting means 240, the sealing film 210 is a waterproof opening 201 by the rise of the fuse 220 ) Tightly shut off.

The fuse 220 has a straight shape, and the straight support includes a rod 221 using a heat conductor, a pipe 222 using a heat conductor, a support 223 having a protrusion using a heat conductor, and a molten material 224. Normally, the rod 221 using the thermal conductor and the support 223 having the protrusion using the thermal conductor are arranged in a row to receive the water pressure and keep the sealing membrane 210 in close contact with the upper portion.

2B is a cross-sectional view of an operating state in which a support 223 having a protrusion using a thermal conductor is separated from side to side due to decomposition of molten material during a fire, and a rod 221 using a thermal conductor falls down by a hydraulic pressure to seal the membrane ( 210) is separated to spray water.
