The structure and working principle of the fire damper The structure of the fire damper is mainly composed of a valve body and an actuator. The valve body is composed of a shell, a flange, a fire damper blade and a blade linkage mechanism. The actuator is composed of a shell, a blade adjustment mechanism, a clutch, and a temperature Fuse, etc., the actuator of the fire damper controls the rotation of the blade through a metal fusible plate and a clutch mechanism

In the pipeline planning of ventilation and air conditioning systems, although it is calculated, if the working conditions of practical projects change, it is required to dispatch the air volume of each part of the system through fire dampers and valves, carry out system debugging, fix the opening of the valves and allocate them reasonably to meet the planning requirements. As an indispensable fire fighting facility in engineering construction equipment, fire dampers can effectively prevent fire extension, it plays a vital role in promoting a safe environment.

The daily inspection and adjustment of the fire damper is required to be done every day, because it is closely related to the working efficiency and service life of the fire damper. If you want to create greater value for the fire damper, please pay attention to the daily inspection and adjustment of the fire damper.

Fire damper: installed on the air supply and return pipelines of ventilation and air conditioning systems, it is usually open. When the gas temperature in the pipeline reaches 70 ℃ in case of fire, the fusible sheet will fuse and the valve will automatically close under the action of torsion spring force. It can meet the requirements of fire stability and fire integrity within a certain period of time. It will output a closing signal when the valve is closed.
