Problems solved by technology
[0003] Moreover, the air valve structure can only be adapted to a specific motor. When the required motor size or driving force changes, the air valve needs to be redesigned.
Therefore, the specific air valve structure and supporting motor can only be applied to specific models. When there are more models, the types of air valves will be more diversified, resulting in low generalization of air valves and increasing the development of the unit. Cost, but also increases the maintenance difficulty of the unit

The invention relates to an air valve device and a fresh air system. The air valve device comprises a mounting plate (2) and an air guide plate (3). A connector which is used for being connected with a driving part (4) is arranged on the mounting plate (2), the air guide plate (3) is detachably fixed to one end of the mounting plate (2), and the mounting plate (2) can drive the air guide plate (3) to rotate under the action of the driving part (4) so that opening and closing operation of a ventilation opening (6) of an air channel can be achieved. By the adoption of the air valve device, an air door is designed to be of a split structure, the mounting plate is only used for transmitting the power of the driving part, and the air guide plate is used for covering the ventilation opening; and according to the ventilation openings with different sizes and shapes, the air guide plate only needs to be designed to be matched with the ventilation openings, the structure of the mounting plate can be unchanged, and therefore the universality of the air valve device can be improved, and the development cost and the maintenance difficulty of units can be reduced.
Description
technical field [0001] The invention relates to the technical field of fresh air systems, in particular to a damper device and a fresh air system. Background technique [0002] According to different building structures and different application scenarios, the design and development of heat exchange fresh air fans often have a variety of different requirements, such as air volume, installation method, performance, etc. The air ducts of heat exchange fresh air fans with different air volumes and different installation methods also have different shapes and sizes, so for heat exchange fresh air fans with different air ducts, different air valve structures need to be designed, resulting in a series of heat exchange fresh air fans. The structure of the air valve is diversified. [0003] Moreover, the air valve structure can only be adapted to a specific motor, and when the required motor size or driving force changes, the air valve needs to be redesigned. Therefore, the specif...
