How does Fire Damper build a safety barrier for the ventilation system?
Publish Time: 2024-08-13
Fire Damper plays a vital role in the ventilation system. It builds a safety barrier for the ventilation system through a series of designs and functions.1. Prevent the spread of fireThe main function of Fire Damper is to prevent the spread of fire through the ventilation duct by automatically closing the valve when a fire occurs. Since the ventilation ducts run through various areas of the building, once the fire spreads through these ducts, it will quickly spread to the entire building, causing serious consequences. The setting of Fire Damper effectively cuts off the propagation path of the fire, buying precious time for fire fighting and personnel evacuation.2. Temperature control mechanismThe working principle of Fire Damper is mainly based on temperature control. When the gas temperature in the pipeline reaches the preset fuse temperature (usually 70℃ or 280℃), the temperature sensitive element inside the Fire Damper will melt or deform, thereby triggering the valve closing mechanism. This mechanism ensures that Fire Damper can respond quickly at the early stage of the fire to prevent the fire from further expanding.3. Multiple installation methodsThe installation location of the Fire Damper is carefully designed to ensure that it can maximize its fire prevention effect. Specifically, the Fire Damper should be installed in the following locations:Fire separation: such as fire walls, fire-resistant walls, etc., to prevent the fire from spreading from one fire partition to another.Where the air duct passes through the partition walls and floors of important rooms or machine rooms: to prevent the fire in the machine room or important room from spreading to other areas through the air duct.On the horizontal pipe section where the vertical air duct meets the horizontal air duct on each floor: to prevent the fire from spreading in the vertical direction.Crossing both sides of the deformation joint: to ensure that the Fire Damper can still play a role when the building structure is deformed.4. Linkage with other fire-fighting equipmentThe Fire Damper can also be used in conjunction with other fire-fighting equipment, such as fire alarm systems, water sprinkler systems, etc. When the fire alarm system detects a fire, it can control the closure of the Fire Damper and start the water sprinkler system to extinguish the fire. This linkage mechanism improves the efficiency of fire handling and further ensures the safety of the building.5. Strict inspection and maintenanceIn order to ensure that the Fire Damper can play a role at critical moments, it needs to be inspected and maintained regularly. The inspection content includes the appearance, installation location, nominal operating temperature, basic functions, etc. of the Fire Damper. Through these inspections, potential problems can be discovered and dealt with in time to ensure that the Fire Damper is always in good working condition.In summary, the Fire Damper has built a safety barrier for the ventilation system through its unique design and function. It can not only prevent the spread of fire, but also work with other fire-fighting equipment to improve the efficiency of fire handling. At the same time, regular inspection and maintenance also ensure the reliability and effectiveness of the Fire Damper.
