Abstract
The invention discloses a valve hand gear for drive of a secondary worm and gear and a cylindrical gear. The valve hand gear comprises an input shaft, wherein a first worm wheel is connected to one end of the input shaft, and a drive gear is fixed on the other end of the input shaft; a first worm is arranged on the first worm wheel so as to drive the first worm wheel to rotate; the cylindrical gear is meshed on the drive gear; a second worm is fixed on the cylindrical gear, and can be rotated along with the cylindrical gear; a second worm wheel is connected onto the second worm; and a valve connecting device is arranged on the second worm wheel and is used for connecting with a valve required to be acted. During a use process, through the drive of the secondary worm and gear and the cylindrical gear, the drive ratio on the first worm can be reduced and is transmitted to the valve connecting device arranged on the second worm wheel so as to control the valve required to be acted, the accurate control of the valve is realized, and the functions of fine adjustment and accurate control on the valve required to be acted can be achieved.
