1. Working principle of ordinary sprinkler head
The working mechanism of ordinary sprinkler head is relatively simple but very efficient. When a fire occurs, the temperature inside the building rises sharply, and the thermistor in the ordinary sprinkler head will sense the temperature change and automatically start the water spraying function. The sprinkler head begins to spray water mist downward and in the direction of the ceiling. According to the design, ordinary sprinkler head sprays 40% to 60% of the water volume downward and forms a wide range of water mist coverage in the ceiling area.
2. Mechanism of spray control of fire
Ordinary sprinkler head plays a key role in the early stage of fire through water mist. Its mechanism of controlling fire is mainly reflected in the following aspects:
Cooling effect: Water mist first absorbs heat quickly through evaporation to reduce the temperature of the fire source area. The evaporation of water absorbs heat and can take away a lot of heat energy from the fire source, slowing down the temperature rise of the flame. The fine particles of water mist can maximize the contact with high-temperature air, thereby improving the cooling effect.
Isolating oxygen: The occurrence of fire is inseparable from the participation of oxygen. Ordinary sprinkler head sprays water mist to make water vapor occupy the air in the fire area. This water vapor blanket can partially isolate the fire source from oxygen, reduce the oxygen supply, and thus reduce the intensity and activity of the flame. The tiny water droplets produced by the water mist help reduce the oxygen concentration in the fire source area, thereby inhibiting the fire source.
Cooling burning materials: In addition to cooling the air, water mist can also directly act on flames and combustible materials to help cool down and reduce the burning rate. Because the sprayed water particles are very small and can penetrate into every corner of the burning area, the cooling effect of the water mist can quickly reduce the temperature of the fire source, reduce the pyrolysis rate of the combustibles, and gradually slow down or stop the combustion process.
Improve the efficiency of extinguishing fires in the early stage: Ordinary sprinklers quickly reduce the temperature and limit the spread of the fire, buying time for firefighters and reducing the further spread of the fire. Because water mist can quickly cool down, it can curb the development of the fire in the early stage of the fire, providing firefighters with sufficient time and conditions to extinguish the fire.
3. The actual effect of ordinary nozzle spray
The effect of ordinary nozzle spray in controlling fire can be reflected in the following aspects:
Improve fire extinguishing efficiency: By spraying water mist, ordinary nozzles can quickly reduce the temperature of local areas and inhibit the spread of flames. This process can greatly improve the efficiency of initial fire extinguishing and effectively reduce the losses caused by fire.
Reduce the risk of fire spread: Ordinary nozzles can not only extinguish flames directly, but also reduce the possibility of fire spread by cooling and isolating oxygen. The water mist covers a wide range, which can not only act on the fire source itself, but also prevent the flame from spreading to other areas to a certain extent.
Reduce casualties: Ordinary nozzles can effectively reduce the temperature and flame intensity of the fire scene by quickly starting and spraying water mist, providing a relatively safe environment, allowing people to have more time to evacuate and reduce the risk of casualties caused by fire.
Adapt to a variety of building environments: The spray method of ordinary nozzles is very suitable for a variety of building environments, especially in places with low ceilings or hanging objects. Water mist can quickly cover the entire area and play a fire extinguishing role.
4. Advantages of ordinary sprinklers
Automatic response: Unlike manual fire extinguishers, ordinary sprinklers are automated devices that can respond immediately when a fire occurs without human intervention. This automatic response capability allows it to work quickly in the early stages of a fire, effectively reducing the time it takes for the fire to spread.
Save water resources: Ordinary sprinklers spray fine water mist, which can cover a wider area and use less water than traditional water columns. Because the water mist particles are tiny, it can fully contact the fire source and maximize the fire extinguishing effect.
Wide applicability: Ordinary sprinklers can be used not only in commercial buildings, residential and industrial plants, but also in various ceiling heights and space layouts. Its flexible adaptability allows it to play an effective role in different building environments.
