Description

Fire fighting pipe device for preventing fire spread

The present invention relates to a fire fighting piping device for preventing the spread of fire, and more particularly, when a fire occurs or a fire spreads through a door, fire extinguishing water is sprayed by a signal detected through a plurality of fire detection means. It relates to a fire-fighting piping system for fire-fighting that prevents the spread of fire that allows the spray nozzles of the to move to the fire detection position and actively focus on extinguishing the fire easily and quickly.

In general, in order to prevent the spread of large-scale fires, various types of firefighting equipment are installed in buildings including apartment houses and various underground facilities, and a water supply pipe for supplying extinguishing fluid to the firefighting equipment is constructed.

Fire hydrants and sprinklers are representative firefighting equipment, and these firefighting equipment extinguish fires by spraying extinguishing fluid.

However, in most water supply pipes, one firefighting equipment installs multiple firefighting equipment in series to supply water, so in case of emergency, firefighting equipment adjacent to the water supply source is capable of repelling the extinguishing liquid with sufficient water pressure, but firefighting equipment located far from the water supply source extinguishes the fire. There is a problem that the water repellency of the digestive juice of insufficient water pressure is made.

Moreover, there is a problem that fire suppression itself becomes impossible because a sufficient amount of extinguishing liquid cannot be supplied with firefighting equipment with low water pressure.

In order to solve this problem, a separate water pump is installed for each firefighting equipment, but this is not preferable because it increases the installation cost of the firefighting equipment.

As another solution, there is an alternative that minimizes the number of firefighting equipment by widening the distance between them. There is a downside to not being able to detect it.

To this end, the fire-fighting piping system of the apartment house of Registration Patent No. 1787089 (2017.10.11.) ensures that sufficient water pressure and water supply for fire suppression can be supplied to the sprinkler, which is a fire-fighting equipment.

That is, in the prior art, the first and second water supply pipes are in communication with the first and second main pipes, respectively, and the first and second water pipes are each supplied with extinguishing liquid to one water supply unit through the first and second branch units as a medium. It is to diversify the water supply route in the connection unit so that a sufficient amount of extinguishing fluid can be supplied from multiple water supply routes in case of emergency.

However, in the prior art, when the stopper bulb supporting the lower part of the pad is thermally expanded and broken by the fire heat transferred through the support in the first branch hole sealed by the pad, the pad falls to the top of the support and the extinguishing solution of the first branch hole flows into the catchment hole. Water is repelled to the outside through the water-repellent port, but in order for the support to be affected by the fire heat, the support must directly contact the fire heat above a certain temperature. If it does not go far enough, there is a fatal problem that the digestive juices cannot be repelled.
