Guide vane linkage bevel gear meshing valve

The guide vane linkage bevel gear meshing valve comprises a shell, a guide vane linkage mechanism and a plurality of guide vanes, the shell is in a cylindrical shape, the guide vane linkage mechanism is located in the center of the shell, and the guide vanes are evenly distributed around the guide vane linkage mechanism in the circumferential direction; the top of each guide vane is connected with the guide vane linkage mechanism through one end of the guide vane intermediate shaft, the root of each guide vane is connected to the wall of the shell in a pivoted mode through the other end of the guide vane intermediate shaft, and the guide vane linkage mechanism is of a bevel gear set structure. Other guide vanes are in mutual linkage around respective guide vane intermediate shafts to achieve synchronous rotation. The bevel gear mechanical structure in the center of the valve is adopted, the guide vane angle is synchronously adjusted to adjust the fluid flow, and the valve is simple in structure, high in safet
