This application relates to a Magnus-type airflow regulating valve, specifically a flow control valve. It includes an inlet duct, at least two branched guide pipes connected to the end of the inlet duct, a rotating component rotatably mounted within the inlet duct, and a driver. The driver in this application drives the rotating component to rotate at a high speed in a specific direction. The rotating component causes the air adhering to its outer periphery to rotate along with it, resulting in different airflow velocities on both sides of the rotating component. According to Bernoulli's principle, the airflow behind the rotating component is directed to the side with the higher airflow velocity and exits through the branched pipe on that side. Since the regulating capacity of this airflow regulating valve is achieved by the rotation direction and speed of the rotating component, the current operating state of the airflow regulating valve can be identified through driver status feedback, improving the problem of inconvenient monitoring of the operating state of the airflow regulating valve. Because there is no resistance mechanism, the system flow characteristics outside the branch where the airflow regulating valve is located remain essentially unchanged, and it will not affect the airflow of other unrelated branches.
