Abstract
The utility model relates to a two-stage planet gear valve control device which comprises a first transmission shaft, a first planet gear, a first switchover part, a second transmission shaft, a second planet gear, a second switchover part, a worm, a worm rod, a valve and an adjusting switch. The first transmission shaft, the first planet gear and the first switchover part form a first planet gear train. The second transmission shaft, the second planet gear and the second switchover part form a second planet gear train. The transmission ratio from the first transmission shaft to the worm rod is reduced through two stages of the planet gear trains to achieve fine adjustment of the adjusting switch. A sensing device and a controlling device can be further arranged on the connection portion of the first transmission shaft to achieve automatic control of the valve.
