Fire sprinkler system is an automatic fire extinguishing system mainly used to detect and control the spread of fire in buildings. The working principle of the fire sprinkler system is to automatically activate the sprinkler heads through temperature sensing. When the temperature reaches the set value of the nozzle (usually 68°C or 93°C), the temperature sensing element (such as the glass ball) of the nozzle breaks and the water flow is sprayed through the nozzle. The entire process is completed automatically without manual intervention. With proper design and regular maintenance, fire sprinkler systems can significantly improve building safety and quickly and effectively protect people and property in the event of a fire.
