The ball body of the ball valve has a channel, and the alignment or misalignment of the channel and the pipeline can be realized by rotating the ball body. When the ball body channel is aligned with the pipeline, the medium can smoothly pass through the valve, so that the pipeline is in a conductive state. When the ball body is rotated by 90 degrees and the channel is perpendicular to the pipeline, the ball body completely blocks the pipeline, preventing the medium from flowing, so as to achieve the purpose of cutting off the medium flow and realize the on-off control of the medium in the pipeline.
