Description

Technical field:

[0001] The utility model relates to the technical field of fire dampers, and more specifically to a fire smoke exhaust fire damper special for modern logistics warehousing. Background technology:

[0002] With the rapid economic growth and people's increasing demand for materials, the circulation of logistics has also increased dramatically. The items in the warehouse are diverse and complicated, and the stored goods are often large. Therefore, the warehouse is most afraid of fire. Modern logistics warehouses are equipped with ventilation systems. Fire dampers need to be installed on the pipelines of the ventilation system to suppress the spread of fire. Fire dampers are mainly based on high-temperature fuses. The regulating controller drives the rotation of the blades to close the channel. However, it was found during use that some regulating controllers will fail after being exposed to high temperatures. When the fire is over, it is necessary to start the ventilation system first to ensure the oxygen in the warehouse, handle the items in the warehouse, and then repair the facilities, including replacing the fire dampers. However, the failure of the regulating controller will cause the operation of the ventilation system. Therefore, it is necessary to provide a channel connecting structure on the fire damper.
