Valve actuating mechanism's manual, automatic switching device

The utility model discloses a valve actuating mechanism's manual, automatic switching device belongs to valve actuator technical field, sets up between handle and automate ware, and the key lies in: include that the axle bed of being connected with the driving shaft and the handle of automate ware, the push rod spare that sets up on the axle bed reach the stop pin that has movement freedom between driving shaft and axle bed with the help of push rod spare. The utility model discloses an useful technological effect is: when the automate ware worked, stop pin and conversion round pin axle played the transmission moment of torsion in order to open the effect of closing the valve, and when the automate ware breaks down or need to safeguard, thereby press down or rotatory conversion push rod makes the stop pin leave driving shaft, the whole driving shaft isolation driving shaft that gets into of conversion round pin axle, and the valve can be realized opening or closing by the twist grip, whole device simple structure, compactness, with low costs.
