Detailed Description

The utility model discloses the device is a actuating lever, and its effect mainly is the valve rotation in the drive butterfly valve.

As shown in fig. 1, a butterfly valve driving rod comprises a driving rod body 1 and a driving motor 2, wherein the driving motor 2 drives the driving rod body 1 to rotate, so as to drive a valve to rotate, and thus a butterfly valve is opened.

As shown in fig. 2 to 5, one end of the driving rod body 1 is connected to an output shaft of the driving motor 2 through a driving part 3, and the driving part 2 is connected to the driving rod body 1 through a thread, so that the driving rod body can be conveniently detached and maintained; the other end of the driving rod body 1 is provided with an output part 5, and the output part 5 is connected to a connecting shaft of the valve so as to drive the valve to rotate. The driving part 3 is provided with a connecting groove 31 with an opening on the upper end surface, the side surface of the driving part 3 is provided with a first threaded hole 32, a locking bolt 33 is arranged in the first threaded hole 32, and the edge of the connecting groove 31 is provided with notches 311 which are uniformly distributed; a second threaded hole 211 matched with the first threaded hole 32 is formed in the side face of the output shaft of the driving motor 2, and a protrusion 212 matched with the notch 311 is formed in the output shaft of the driving motor 2. When the output shaft of the driving motor 2 is inserted into the connecting groove 31, and the output shaft of the driving motor 2 is inserted into the bottom of the connecting groove 31, the first threaded hole 32 and the second threaded hole 211 correspond to each other, and the locking bolt 33 is tightened, so that the output shaft of the driving motor 2 is arranged on the driving part 3, and the protrusion 212 on the output shaft of the driving motor 2 is matched with the notch 311 on the driving part 3, so that the acting force between the output shaft of the driving motor 2 and the driving part 3 can be increased, and the rotation is promoted.

The depth of the connecting groove 31 is equal to the distance between the upper end surface of the protrusion 212 and the bottom surface of the output shaft of the driving motor 2. This ensures that the projection 212 is completely fitted in the recess 311, and increases the force between the output shaft of the drive motor 2 and the drive section 3, facilitating rotation.
