Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhaust fire damper actuators, in particular to an intelligently controlled smoke exhaust fire damper actuator. Background Art

[0002] With the development of my country's economy and society, there are more and more high-rise buildings, and high-rise buildings pay the most attention to fire prevention. Therefore, smoke exhaust fire dampers are generally installed in the ventilation systems of high-rise buildings. The blades of the smoke exhaust fire dampers can be opened for smoke exhaust, and the blades can be closed to prevent the thick smoke from spreading to other rooms and corridors. Generally, the opening and closing of the blades of the smoke exhaust fire dampers are controlled by the actuator. The blades are usually in a closed state. Once a fire occurs, the actuator controls the opening of the blades of the smoke exhaust fire dampers to exhaust smoke. If the smoke exceeds a certain temperature, such as 280°C, the smoke has sparks. At this time, if the blades of the smoke exhaust fire dampers are not closed to prevent smoke exhaust, it will help the fire spread. Therefore, the actuator is required to close the blades. The actuators of the prior art usually adopt electric and manual control. It is necessary to connect the line from the control room to the actuator to make it work normally. The wiring cost is high and the installation is inconvenient. When the valve needs to be opened and closed, it is necessary to manually press the button in the control room. In case of an emergency, the operation cannot be performed quickly, and there are certain safety hazards. Summary of the invention
