Description
The air duct damper is an indispensable central air-conditioning terminal accessory in the ventilation, air schedules, and air purification engineering of industrial plants and civil buildings. It is generally used in air conditioning and ventilation system pipes to control the air volume of branch pipes. It can also be used for fresh air and return air mixed scheduling.
1. Structural characteristics of the air duct damper
(1) The air duct damper has four specifications when the blade width is all the same. The blade shape is a diamond-shaped double blade, and the blades are soft overlapped, so the sealing performance is excellent.
(2) The damper body frame of the air volume control valve is injection molded from polypropylene material, which has good sealing performance. The product itself has the characteristics of anti-acid and alkali corrosion and can be widely used in exhaust gas exhaust pipes.
(3) The dispatch damper is divided into manual and electric. The damper body structure and specifications are the same.
2.the characteristics of the air duct damper
(1) The takeover standard of the split multi-leaf air volume dispatching damper is the same as the rectangular air duct standard of the national ventilation duct standardization.
(2) The blades of the air volume dispatching dampers are side-opening and forward-opening, which are used as dispatching valves in ventilation, air dispatching, and air purification systems.
(3) According to the test, the air-tightness of the air volume dispatching damper is good, and its relative air leakage is about 5%, and the dispatching performance is good.
3. the scope of application of the air duct damper
It is widely used in industrial, mining, and civil building HVAC systems to accurately schedule airflow. It is one of the key pieces of equipment for controlling ventilation modes in various environments. Its main features are flexible work, low noise, small leakage, reliable structure, safety, and convenience.
The above are the main functions and features of the air duct damper. There are also different types of dampers for different occasions and needs.
