Wedge-shaped flow meter with pressurizing function

The invention discloses a wedge-shaped flow meter with a pressurizing function. The wedge-shaped flow meter comprises a tube body, wherein a wedge-shaped pressure regulating device is arranged on thetube wall of the front end of the tube body; the wedge-shaped pressure regulating device comprises a wedge-shaped block with a rotating shaft; with the shaft as the circle center, the two ends of thewedge block are symmetrical and equal-radius arcs including an outer side arc and an inner side arc with the same top height, and the arc length of the outer side arc is larger than the arc length ofthe inner side arc. And the pressure tapping pipe is arranged on the pipe body at the rear end of the wedge-shaped pressure regulating device. Through the symmetrical wedge-shaped pressure adjusting devices, the flow and the flow speed of fluid flowing into the pressurizing pipe are adjusted in the longitudinal direction respectively, and the pressurizing effect is achieved through diameter changing of the pressurizing pipe
