Firefighting nozzle: the "automatic fire extinguishing guard" beside you
1、 Who is it?
A fire sprinkler is a small device installed on the roof or wall, like a "small faucet", that does not spray water normally but automatically sprays water to extinguish a fire.
2、 How does it work?
Sensing temperature: There is a glass ball inside the nozzle, which contains a special liquid. The higher the temperature, the faster the liquid expands.
Automatic water spray: When the temperature reaches the set value (such as 68 ℃), the glass ball bursts, the water pressure opens the nozzle, and the water flow is evenly sprayed out.
3、 Common types
Vertical type: with the nozzle facing downwards, suitable for areas without suspended ceilings.
Pendant type: with the nozzle facing upwards, commonly found in spaces with suspended ceilings.
Side wall type: Installed on the wall with a metal cover plate.
4、 How important is it?
Quick fire extinguishing: In the early stages of a fire (within 3 minutes), automatic water spraying is used to cool the fire source and isolate oxygen.
Case: In 2025, an electric vehicle in a residential area caught fire, and the nozzle was promptly activated to avoid the fire.
5、 Precautions
Do not cover: Do not place anything within 1 meter around the nozzle.
Don't hang: Clothes and decorations should not be hung on the nozzle.
Regular inspection: Ensure that the nozzle glass ball is intact and free of coating.
