Abstract
The utility model relates to a valve manual device with two-stage transmission of worm wheels and worms and a cylindrical gear. The valve manual device comprises an input shaft, one end of the input shaft is connected with a first worm wheel, a transmission gear is fixed at the other end of the input shaft, a first worm is arranged on the first worm wheel to drive the first worm wheel to rotate, the cylindrical gear is meshed on the transmission gear, a second worm is fixed on the cylindrical gear, the second worm can rotate along with the cylindrical gear, a second worm wheel is connected on the second worm, and a valve connection device is arranged on the second worm wheel to be used for being connected with the valve needing to be operated. In a using processing, transmission between the two stages of worm wheels and worms and the cylindrical gear can reduce the transmission ratio on the input shaft and is transmitted to the valve connection device arranged on the second worm wheel to control a valve needing to be operated. Thus, accurate control on the valve is achieved, and further the functions of fine adjustment and accurate control on the valve are achieved.
