A fire damper actuator is installed in a high-rise building and is used to open and close the smoke exhaust port of a fire prevention and smoke exhaust ventilation system.
And the safety device is formed by the mutual matching electromagnet, swing rod, and swing frame with rotating column. The cam is clamped on the belt, and the upper and lower housings with springs are installed on the hollow shaft. The handle will The upper and lower housings are connected as a whole and cooperate with the fuse to form an operating device. It also includes the gear on the motor shaft meshing with the gear on the controller shaft through the gear set, the rotating shaft on the gear of the controller is connected with the rotating shaft fixed on the hollow shaft through a pull rod to form an electric operating mechanism, which is electrically reset and operated, and is more convenient and rapid to use.
Smoke fire damper actuator is one of the commonly used and reliable actuator types. Single-phase or three-phase motor is used to drive gear or worm gear to drive the valve stem nut. The valve stem nut makes the valve stem move to open or close the valve. Smoke fire damper actuator can quickly drive large-size valves. In order to protect the valve from damage, the limit switch installed at the end of the valve stroke will cut off the motor power supply. At the same time, when the safety torque is exceeded, the torque sensing device will also cut off the power of the motor, the position switch is used to indicate the switching state of the valve, and the hand wheel mechanism with the clutch device can manually operate the valve in the event of a power failure.
The main advantage of this type of actuator is that all components are installed in a housing, in this waterproof, dustproof, explosion-proof enclosure integrates all the basic and superior functions, the main disadvantage is that when the power failure, the valve can only remain in place, only the use of backup power system, the valve can achieve a fail-safe position (failure on or off).
Function of smoke-proof fire damper actuator: normally open at ordinary times, valve can be closed manually, fire damper electrical signal command or temperature sensor, equipped with 70-degree temperature sensor, main technical data: control voltage DC24V micro switch contact capacity AC380V current ≤ 0.5A adjustable 5-gear air volume manual reset torque 15N · M spindle aperture Φ12 ㎜ spindle height 110 ㎜ weight: 1.3 ㎏.
The use of smoke fire valve actuator:
Generally installed in the smoke fire damper-multi-leaf smoke outlet-multi-leaf air supply-positive pressure air supply.

Function:
1 Open the valve manually or by electrical signal to exhaust smoke, and close it again when the temperature rises to 280 ℃.
2DC24V power control valve open.
3 manually open the valve, manual reset.
4 After the valve is opened, the output electrical signal is interlocked with other related equipment.
5 This product has been installed to open and close two kinds of torsion spring, in the valve body without the installation of tension spring.
Since the fire damper is continuously upgraded and updated from the smoke exhaust system, you will find that the fire damper actuator installed in the modern fire control system has more and more technical advantages. In the process of application, the advantages and characteristics of this technology are found. In the process of promotion, most of the fire control systems are installed and applied, and the functions and technical advantages brought by them are more and more ideal, achieved a trustworthy choice for customers.
After the output valve opening signal of the fire damper actuator is displayed in the execution system, it will be directly transmitted to the computer, which will be more convenient for the control process. Therefore, from this perspective, only after knowing the technical advantages and characteristics, you will find that after the valve is opened, the working efficiency in the application process will be higher and higher, it is still very helpful in the implementation process.
