What role does fire damper play in the fire protection system

Fire dampers play a crucial role in the fire protection system. They are not only an important component of the fire protection system, but also play a crucial role in the event of a fire. The following is a detailed explanation of the main role and function of fire dampers in fire protection systems:
To prevent the spread of fire:
The main function of fire dampers is to automatically close and cut off ventilation ducts in the event of a fire, preventing the fire from spreading to other areas through the ventilation system. This is the most basic and core function of fire dampers.
When the temperature of the flue gas in the pipeline reaches 70 ℃, the temperature sensor inside the fire damper will sense the temperature change, thereby triggering the closing mechanism of the fire damper. In the smoke exhaust duct, when the smoke temperature reaches 280 ℃, the smoke exhaust fire damper will automatically fuse and close, further ensuring that the fire will not spread through the smoke exhaust system.
Control smoke flow:
In addition to preventing the spread of fire, fire dampers can also control the flow of smoke. When a fire occurs, the closure of the fire damper can block the spread of smoke through ventilation ducts to other areas, creating better conditions for personnel evacuation and firefighting and rescue work.
As a key component of the fire protection system:
Fire dampers are an important component of the fire protection system. They work together with fire detectors, alarm systems, fire suppression systems, and other equipment to form a complete fire protection system. In the event of a fire, fire dampers can quickly respond and function, providing strong support for fire prevention and control.
Classification and application:
Fire dampers can be divided into various structures according to their functions, such as smoke exhaust valves, smoke exhaust fire dampers, fire control valves, smoke and fire control valves, etc. These different types of fire dampers are widely used in fire protection systems in commercial buildings, public facilities, hospitals, and other places based on their application scenarios and performance characteristics.
Maintain the integrity of the fire protection system:
The normal operation of fire dampers is crucial for maintaining the integrity of the fire protection system. To ensure that fire dampers can be reliably closed and function in the event of a fire, regular maintenance and upkeep are required. This includes checking the appearance, sealing performance, integrity of transmission mechanisms and other components of fire dampers, as well as cleaning and lubricating related components.
Fire dampers play a crucial role in preventing fire spread and controlling smoke flow in fire protection systems. As an important component of the fire protection system, fire dampers work together with other fire equipment to provide strong support for fire prevention and control. To ensure the reliable operation of fire dampers, regular maintenance and upkeep are required.
