What is the function of fire dampers

Fire dampers play a crucial role in buildings, mainly reflected in the following aspects:
Fire resistance function: The fire damper can meet the requirements of fire resistance stability and integrity within a certain period of time. The valve body shell is made of high-quality metal materials, ensuring that the valve will not deform, rupture or produce gaps due to temperature rise in a fire, effectively preventing the spread of fire.
Control smoke diffusion: Fire dampers are usually used in conjunction with smoke exhaust systems to prevent smoke from spreading to other areas of the building through ventilation ducts by closing the valves in the event of a fire. This helps to reduce the impact of smoke on personnel evacuation and firefighting rescue work, and improve the overall safety of buildings.
Adjusting air volume: Fire dampers also have the function of adjusting air volume. Under normal circumstances, fire dampers can control the airflow in the ventilation ducts by adjusting their opening to meet the air circulation requirements inside the building.
Linkage control: Modern fire dampers are usually equipped with electric actuators that can achieve linkage control with the fire control center. When the fire detector detects a fire alarm signal, the fire control center can automatically close the fire damper, cut off the ventilation pipes in the fire area, and prevent the fire from further spreading.
Fire separation: The setting of fire dampers can divide a building into several fire compartments. When a fire occurs, closing the fire damper can limit the fire to a smaller area, prevent the fire from spreading to other areas, and provide favorable conditions for firefighting and rescue work.
Easy smoke exhaust: In the early stage of a fire, the fire damper is in an open state, which is beneficial for smoke exhaust. This helps to reduce toxic smoke and heat at the fire scene, creating better conditions for personnel evacuation and firefighting and rescue work.
In summary, fire dampers play an important role in building fire resistance, controlling smoke diffusion, adjusting air volume, linkage control, fire separation, and facilitating smoke exhaust. By properly setting and using fire dampers, the fire safety level of buildings can be effectively improved, and the safety of personnel and property can be protected.
