In addition to the electric explosion-proof electric valve device, there is also a manual wheel, which is mainly used for manual adjustment and control when the electric actuator cannot work. However, for the explosion-proof electric valve device with large pipeline diameter or poor lubrication, the operator is often difficult to adjust and control through the manual wheel.
At present, there is a kind of explosion-proof electric valve intelligent actuator reduction device, the worm gear and worm gear mechanism including worm, worm gear ring and front shaft bearing cap and rear shaft bearing cap, worm gear ring rotation installed on the box, installed on the box and worm gear ring third external tooth mesh, front shaft bearing cap and rear shaft bearing cap seal installed on the box, and the worm extends out of the front shaft bearing cap. But the worm extends out of the front shaft bearing cap and the hand wheel is directly connected, manual operation because of the transmission speed ratio is small, manual is more laborious, encounter a larger valve, the rotation of the hand wheel is difficult, often can not turn the valve.
Therefore, in order to solve the above problems, the manufacturer provides an explosion-proof electric valve actuator manual wheel improvement structure, the improvement structure is mainly to increase the hand wheel gear at the front end of the hand shaft, and cooperate with the reduction gear group of the reduction wheel, to achieve deceleration, so that manual operation is more labor saving, to avoid the actuator hand wheel manual operation can not turn the valve.
