One of that air blade is adjusted to be connected with rotatable master control bar in centerline, remaining N-1 tune air blade is in
It is connected with rotatable control-rod at heart line, one end of the master control bar and control-rod is connected to the end cap of outer barrel the center point
On, the other end is pierced by barrel and is connected with connection sheet in end, and the both ends of the connection sheet are respectively articulated with single pole ball cup, adjacent
Coupling bar is installed between the single pole ball cup of connection sheet,
The end that master control bar is pierced by barrel is equipped with worm and gear fan valve executor, rotation of worm gear worm screw fan valve executor
Master control bar is with rotation when handwheel.
Further, the maximum rotation angle of the rotation of worm gear worm screw fan valve executor is 90 °.
Further, the fan-shaped quantity for adjusting air blade is 8.
Further, the shape of the connection sheet is diamond shape.Due to the symmetry of diamond shape, connection sheet both ends coupling bar can be made
Torque is equal.Ensure the synchronism of each tune air blade rotation.
Further, the control-rod is 2/3rds of main control lever length.
The working principle of the utility model is that worm and gear fan valve executor is connect with master control bar, rotary air valve actuator
Handwheel, the connection sheet of end rotates synchronously when master control bar rotates, at this point, the hinged single pole ball cup in connection sheet both ends drives connection
Extension bar is mobile, and the connection sheet of the other end is passed to by coupling bar, links by the transmitting of each coupling bar, realizes and control in each connection sheet
The synchronous rotation of bar processed achievees the purpose that adjust the adjustment of air blade angle.
Compared with prior art, the utility model has the beneficial effects that:
1, the utility model is linked by the combination of worm and gear fan valve executor, coupling bar and single pole ball cup, to adjust
Section adjusts the rotation or even closure of air blade, easy to operate, realizes accurate adjusting, ensure that the stability of ventilation, dedusting and other effects.
2, the utility model can make that air blade is adjusted to be rotated by 90 °, and close from complete to standard-sized sheet, can accomplish step-less adjustment, worm gear snail
Bar fan valve executor can be self-locking, and maximum pressure can bear 1500pa.
