A directional fire extinguishing system for fire sprinkler heads

Abstract

The invention discloses a directional fire extinguishing system for a fire-fighting sprinkler head, which comprises a sprinkler head, and a directional water spray mechanism is arranged on the sprinkler head, and the directional water spray mechanism includes a mounting block fixedly connected to the bottom of the sprinkler head. There are four control cavities inside the block, the inner walls of the four control cavities are sealed and slidingly connected with piston plates, and the side walls of the installation block are fixedly embedded with four heat conduction plates, and the four heat conduction plates respectively extend to four In the control cavity, the space between the heat conduction plate and the piston plate in the four control cavities is filled with low-boiling evaporating liquid, and the space far away from the heat conduction plate in the four control cavities is filled with magnetic fluid. Four placement cavities are arranged inside the block, and the four placement cavities are respectively communicated with the four control cavities through connecting pipes. The invention avoids the waste of water resources, and at the same time, most of the water is used for fire extinguishing, which can also increase the impact force of the water sprayed from the nozzle and improve the fire extinguishing effect.

Description

technical field [0001] The invention relates to the technical field of fire sprinklers, in particular to a directional fire extinguishing system for fire sprinklers. Background technique [0002] With the continuous improvement of people's safety awareness, now, some public places will be equipped with fire sprinklers for fire extinguishing. The high temperature of the fire will make the liquid in the glass body expand and crush the glass body, and then the water in the fire pipe Can flow out, carry out fire extinguishing, but, existing fire sprinkler head, especially the fire sprinkler head that is used in places such as some company's office buildings has some problems. [0003] Since fires in office buildings and other places are generally caused by some electrical equipment or power lines, when a fire occurs in these places, there is generally only one fire source, and the fire source is not necessarily located in the center of the fire sprinkler head. At the lower end,...

Problems solved by technology

[0003] Since fires in office buildings and other places are generally caused by some electrical equipment or power lines, when a fire occurs in these places, there is generally only one fire source, and the fire source is not necessarily located in the center of the fire sprinkler head. At the lower end, when the fire sprinkler head sprays water, the water will splash on the splash plate and then splash around, so this will cause a large part of the water used to extinguish the fire to be sprayed to the unfired area, and only a part Water can be sprayed to the corresponding fire source point. On the one hand, most of the water will be wasted, wasting water resources. On the other hand, the amount of water used to extinguish the fire is less, and the sprayed water spreads around , so that the impact force of the sprayed water is low, which makes the fire extinguishing effect worse. Therefore, it is necessary to design a directional fire extinguishing system for fire sprinkler heads to solve the above problems
