Basic introduction to fire sprinklers
Fire sprinkler systems are fire-fighting equipment used to automatically detect and extinguish fires. It controls and extinguishes the fire source by spraying water or other fire extinguishing media, thereby preventing the fire from spreading and expanding.
The working principle of the automatic sprinkler system is based on automatic detection and automatic fire extinguishing. The system consists of a series of sprinkler heads connected to the piping system and containing a fire-extinguishing medium (usually water). When the system detects a fire or high temperature, the relevant sprinkler heads will automatically start, release the fire extinguishing medium, and spray it near the fire source to extinguish the flames.
Fire sprinkler systems are usually divided into different zones, each of which can work independently. This zoning design helps deliver the fire extinguishing agent to the fire source more accurately and reduces the waste of fire extinguishing agent.
Fire sprinkler systems are usually equipped with an independent water supply system, including water pumps, water tanks or water sources, to ensure adequate water pressure and water supply in the event of a fire.
Sprinkler selection depends on fire risk and environmental conditions. Different types of sprinkler heads can release different amounts and types of fire extinguishing media to suit different situations.
Automatic sprinkler systems are usually combined with fire detection systems, such as smoke detectors, heat detectors, etc., to detect fire sources early and automatically activate the sprinkler system.
Systems often have a variety of safety measures to prevent accidental activation, such as using independent detection devices to ensure they do not activate before an actual fire occurs.
Application areas: Automatic sprinkler systems are widely used in commercial buildings, industrial facilities, warehouses, hotels, medical institutions, residences and other places to provide fire protection.
The automatic sprinkler system is an important fire-fighting equipment that can quickly extinguish the fire source in the early stages of a fire and reduce casualties and property losses.
What are the different types of fire sprinklers?
Fire sprinklers are equipment used to control and extinguish fires. There are many different types of fire sprinklers based on their design and working principles.
Wall-mounted sprinklers: This is the most common type and is usually installed on the ceiling of a building. They have a glass tube or fuse that breaks when the temperature rises to a certain level, releasing water.
Dry sprinklers: These sprinklers are separated from the water and use compressed air or nitrogen to maintain pressure in the pipes. When a fire alarm occurs, the valve opens, allowing dry powder or water to enter the pipe and spray out. This type of sprinkler is often used in cold climates where pipes freeze.
Pre-action sprinklers: These sprinklers are connected to the fire detection system and automatically release water based on a signal from the detector. They allow precise operation based on the location and severity of the fire, reducing water loss.
Foam Sprinklers: These sprinklers are used to extinguish fires involving flammable liquids, such as oils and solvents. They release foaming chemicals to extinguish the source of the fire and form a layer of foam on the surface of the liquid to stop the flames from spreading.
High-pressure sprinklers: These sprinklers use higher water pressure to deliver large amounts of water quickly and are used to fight large fires, such as industrial facilities or oil fields.
Gas Sprinklers: These sprinklers use dry powder or other chemical gases to extinguish fires instead of water. They are often used in places such as electrical equipment rooms where water cannot be used.
Liquefied gas sprinklers: These sprinklers use liquefied gas, such as carbon dioxide or Freon, to extinguish fires. They are widely used near electrical equipment and other sensitive equipment.
