Description

Sprinkler with drain on head

In order to prevent freezing of piping and sprinkler head due to the water of the sprinkler pipe and the sprinkler head, the present invention drains the digestive water without temporarily disconnecting the connecting parts such as the union constituting the sprinkler. It relates to a sprinkler having a drain in one head to enable.

More particularly, the present invention relates to a sprinkler provided with a drainage device in one head to drain digestive water through a drain hole formed in a sprinkler head or a drain hole of a sprinkler head in a state in which the head is coupled to a sprinkler.

In general, according to the National Fire Safety Standards (NFSC) 103 Article 10, paragraph 7, 3 and 7, dry sprinkler equipment should be installed in the underground parking lot where the pipe is exposed to the outside to prevent freezing of the sprinkler and pipe in winter. These dry sprinkler installations must be equipped with a bottom up sprinkler head, but if a dry pendant sprinkler head is used, top down sprinkler installations may be applied.

Sprinkler is a kind of automatic fire extinguishing system, and the drainage pipe is arranged vertically and horizontally on the ceiling of the building, and the sprinkler head is installed at the end of the sprinkler at regular intervals and connected to the water supply.

When the sprinkler's head receives heat due to a fire and reaches a certain temperature (67-75 ° C), the fuse blocking the head melts to open the drain hole, and the pressure water strikes the head's watering pin to spray water over a wide range. At the same time as the watering, the fire extinguishing pump operates automatically and an alarm sounds. Watering will continue unless the main valve is manually locked. These sprinklers are installed in windows, entrances, ventilation openings, etc. in addition to wooden building.

The installation of sprinkler is suitable for fire extinguishing equipment in the part where people have a lot of combustibles and buildings that have a great effect on liquid fire, and are difficult to find fire or extinguish. The scope of application is very wide, as it can expect nighttime fire fighting activities. It usually operates at 67 ~ 180 ℃ but depends on the type. The location, layout, and amount of waterproofing are prescribed as firefighting methods, depending on the type of building and the degree of interior.

If the sprinkler is operating normally, install a test valve in the toilet, etc., and check whether the sprinkler is operating normally in the test valve. Because sprinkler sprays water in all directions, spraying water directly from the ceiling of homes, offices, etc. causes the surrounding wallpaper, furniture, office appliances to get wet.

As shown in Figure 1, the sprinkler according to the prior art,

Fire extinguishing water supply pipe (2) fixed to the floor of the slab (1) of the building and connected to the water supply source,

Coupling water pipe (2) is connected to the "T" shaped connecting pipe (3) connected to the joint, and maintains a predetermined length of the joint connecting pipe 4 (distance between the slab (1) of the building and the ceiling panel (5) The sprinkler head 6 is fixed to the lower end after arbitrarily adjusting the length of the branch pipe according to

Digestion water in the digestion water supply pipe (1) and the joint connecting pipe (4) can be drained.

As described above, after the extinguishing water is drained from the extinguishing water supply pipe (1) and the joint connecting pipe (4), after rewinding the leak-proof tape to the coupling portion (6a) (referring to the screw portion) of the sprinkler head (6) Reassemble by screwing into the lower end of the joint connector (4). That is, the process of temporarily separating and reassembling the sprinkler head 6 with respect to the joint connecting pipe 4 is required in order to drain the digestive water supply pipe 1, the joint connecting pipe 4, and the sprinkler head 6. In addition, the work time is excessively excessive and the workability is inferior.

In addition, repeated disassembly and reassembly of the joints 4 and the splices 6a of the sprinkler head 6 for drainage causes wear and breakage of these parts. As a result, when the airtightness of the coupling portion of the joint connector 4 and the sprinkler head 6 is loose, and leakage occurs through the gap, the surrounding ceiling panel or wallpaper is contaminated, and thus the reliability is low.
