Detailed Description
The double-shaft double-speed-ratio valve manual device shown in fig. 1 comprises a hand wheel, a box body 1, a worm wheel 2, a worm 3, a first transmission group 4, a second transmission group 5 and a transmission group 6, wherein the worm wheel 2 is matched with the worm 3, the transmission group 6 is in transmission connection with the worm 3, the first transmission group 4 and the second transmission group 5 are in transmission connection with the transmission group 6 respectively, the speed ratio of the first transmission group 4 to the transmission group 6 is smaller than that of the second transmission group 5 to the transmission group 6, and the first transmission group 4 and the second transmission group 5 are connected with the corresponding hand wheel respectively. The corresponding hand wheels are rotated to respectively drive the worm and gear 3 to operate. When a large-flow medium in the valve needs to be opened and closed due to circulation, the hand wheel corresponding to the second transmission set 5 is rotated because the required torque is larger; when the valve is empty or the flow rate is small, the hand wheel corresponding to the first transmission set 4 is rotated.
One end of the worm 3 is connected with a worm gear 21 through a double flat key, the transmission group 6 comprises a secondary gear shaft 61 and a secondary gear 62, the secondary gear 62 is fixed on the end part of the secondary gear shaft 61 through a key connection, the secondary gear 62 is respectively connected with the first transmission group 4 and the second transmission group 5, the secondary gear shaft 61 is meshed with the worm gear 21, and therefore power is input from the secondary gear 62 and output to the worm 3 from the secondary gear shaft 61.
