Circular pipeline one-way valve based on Tesla valve principle

The invention relates to the technical field of flow control, and provides a circular pipeline one-way valve based on a Tesla valve principle, which comprises a valve pipe and at least three flow guide groups, and the valve pipe is provided with a medium flow channel, and a first opening and a second opening which are communicated with the medium flow channel; the at least three flow guide sets are arranged in the medium flow channel, the flow guide sets are arranged along the central axis of the valve pipe in an array mode, each flow guide set comprises a positive flow guide taper pipe and a deviation flow guide taper pipe, and the positive flow guide taper pipes are arranged in a gradually-shrinking mode from the first opening to the second opening; the deflection flow guide taper pipes are arranged in the mode that the first opening is gradually shrunk towards the second opening, the end openings, close to the second opening, of the deflection flow guide taper pipes are arranged towards one side of the def
