The multi-way ball valve can flexibly control the confluence, the diversion and the switching of the flow direction of the medium on a pipeline, and can close any channel to connect the other two channels. The three-way ball valve has a T shape and an L shape. The T shape can make three orthogonal pipelines mutually communicated and cut off a third channel, thereby playing the roles of shunting and converging. The L-shaped three-way ball valve type can only connect two mutually orthogonal pipelines, cannot simultaneously keep the mutual communication of a third pipeline, and only plays a role in distribution. The ball valve is divided into: pneumatic ball valves, electric ball valves, manual ball valves.
But the existing multi-channel ball valve structure has certain defects: 1. a sewage pipeline is not provided with a mechanism capable of monitoring the sewage quality, and a method and equipment capable of quickly shunting the sewage are not provided after the heavy metals in the sewage exceed the standard; 2. in northern factories in cold winter, industrial sewage is extremely easy to freeze in the ball valve and freeze the ball valve, so that the ball valve cannot work continuously, and parts in the ball valve are easily damaged due to too low temperature in the ball valve; 3. the current ball valve is unsuitable to be used for flow control through the ball valve is half-opened, under the condition that sewage in the ball valve need reduce flow temporarily, need rotate the ball valve to the position of the water pipe of alignment not completely, but the impact of rivers can't be born to current ball valve, consequently makes ball valve leakproofness worsen very easily.
To this end, a multi-channel ball valve structure is proposed.
