Medium size, electrical signal, manual fire damper actuator

A manual fire damper actuator is a device used to control the opening and closing of a fire damper, and is usually operated manually to achieve precise control of the fire damper. The following is a detailed introduction to the manual fire damper actuator:

1. Definition and function

The manual fire damper actuator is an important part of the fire damper system, which allows operators to directly control the opening and closing status of the fire damper manually. When a fire occurs, the fire damper can automatically close to block the spread of fire and smoke, while the manual fire damper actuator provides a means of manual intervention in special circumstances (such as failure of the automatic control system).

2. Structure and working principle

The manual fire damper actuator is usually composed of handwheels, handles, transmission mechanisms and other components. The operator turns the handwheel or handle to transmit force to the valve plate or valve sheet of the fire damper through the transmission mechanism, thereby changing its open or closed state. This actuator has a simple structure, is easy to operate, and has high reliability and stability.

3. Application scenarios

Manual fire damper actuators are widely used in ventilation and air-conditioning systems of various buildings, especially in areas where fire dampers need to be installed, such as where pipes pass through firewalls, floors and other locations. By installing a manual fire damper actuator, it can be ensured that the opening and closing status of the fire damper can be quickly and effectively controlled in an emergency, thereby ensuring the fire safety of the building.

IV. Precautions

When selecting a manual fire damper actuator, the appropriate model and specification should be selected according to actual needs, and it should be ensured that it meets the requirements of relevant standards and specifications.

Before installation, the appearance and internal structure of the actuator should be carefully checked to see if it is intact, and whether the transmission mechanism is flexible and reliable.

During the installation process, the operation should be carried out in accordance with the requirements of the instructions to ensure that the installation is correct, firm and reliable.

Regularly inspect and maintain the actuator to ensure that it is in good working condition.

In summary, the manual fire damper actuator is an indispensable and important part of the fire damper system, and its performance and reliability are directly related to the fire safety of the building. Therefore, sufficient attention and concern should be given during the selection and use process.
