On another side of the connecting plate 3, the right-angle deceleration device 2 is connected to the hollow deceleration device 6 via the second hole and fixed to the hollow deceleration device 6 by screws.

[0034] The compensation connection element 4 is inserted into the hollow deceleration device 6 and fixed by screws. The compensation connection element 4 is provided with an inner groove. An inner groove of the connection adapter 5 is selected according to the dimensions of a handwheel shaft of the valve. A housing of the connection adapter 5 has a shape adapting to the shape of the inner groove of the compensation connection element 4, and the connection adapter 5 can be fixed to the handwheel shaft of the valve by screws.

[0035] The servo motor 1 is connected to the right-angle deceleration device 2 by the screws. The present invention adopts a 750W servo motor having a maximum rotational speed of 3000 rpm and having properties such as small size, large torque, light weight and low power, a not very powerful electric source is sufficient for operation during use.
