Abstract: For cone valve throttle orifices with different structure parameters, first, the characteristics of triangular (45°, 53° and 60°), U-shape and rectangular throttling notches are analyzed and the corresponding calculation formulas of the valve port areas are deduced. Then, the flow coefficients of different valve cores in cone valve are obtained according to the experiments on the flow and pressure characteristics and the Matlab program. Results show that the flow coefficients of the cone valve are not only related to the system pressure and valve port area, but also related to the configuration feature. The flow coefficient of cone valve increases with the pressure, and it decreases with the increase in the orifice area. The stability of the flow coefficients of triangular valves with 53° and 60° throttle grooves is better than the other three kinds of structure; and the flow coefficients of triangular valve with 45° throttle groove is most unstable.

Key words: fluid power transmission and control, cone valve, throttling groove, valve port area, flow coefficient
