Four-way ball valve operating mechanism capable of avoiding misoperation

The invention belongs to the field of four-way ball valves, particularly relates to a four-way ball valve operating mechanism capable of avoiding misoperation, and provides the following scheme aiming at the problems that when an existing four-way ball valve works normally, misoperation often occurs, a valve rod is reversely rotated and a device is damaged due to the fact that the situation in the four-way ball valve cannot be seen. The valve comprises a valve body and two semi-cylindrical shells, a valve rod is arranged in the valve body, the top of the valve rod extends to the position above the valve body, the four side faces of the valve body are fixedly connected with communicating connecting pipes, and one end of each connecting pipe is fixedly connected with a flange. The connecting rod can only move clockwise along the first vertical groove, the first transverse groove, the second vertical groove and the second transverse groove in sequence and cannot move reversely, so that misoperation is avoided, t
