の風量を１呆つことになる。First, the principle of the present invention will be briefly explained. When the damper blade receives airflow, a large static pressure is generated on the back surface, and since the blade end on the closing side is large, this pressure acts on the blade shaft as a blade closing torque. An example of this characteristic curve is shown in FIG. Therefore, if a torque that is balanced with the closing torque corresponding to the required air volume and the blade opening at that time is applied to the blade shaft, the blade opening will be one less than the air volume at that time.

作用する負圧の差が羽根の閉鎖力となる。FIG. 3 shows the air volume and blade closing torque in the air duct with exemplary dimensions in relation to the damper opening, and the spring torque is superimposed thereon. For example, in the case of an air volume of 3000 rd/h, the illustrated spring can stably reach the required air volume at an opening angle of 49° to 63°. Therefore, when the lever 19 shown in FIGS. 1 and 2 is set to a required torque position, the damper blade 11 maintains this position at a predetermined air volume position where the closing force and spring force are balanced. As mentioned above, the difference in negative pressure acting on the back surface of the blade due to the airflow passing through the air duct becomes the closing force of the blade.

簡単に得ることができる。During operation, when adjusting the air volume, loosen the set screw 21 shown in FIG. 2. The damper blade 11 is a spring when the air volume is 0! It is kept in the fully open position by the action of 7 or 60. When the blower is driven to start blowing air, the blades tend to move in the closing direction due to negative pressure acting on the back surface of the blades. The blade glue stops at the balance position between this closing force and the spring acting force,
Since a specific air volume is obtained, the spring position at this time can be displayed on the scale 65 as the air volume. In practice, once the air duct and blower are identified, the air volume is displayed on a scale, making it easy to obtain the desired air volume.
