| Abstract: | The orifice area characteristics and the equivalent orifice area of three typical shape orifice valves are analyzed . And the phenomenon of shift of orifice location in hydraulic valve is presented and analyzed. The equivalent orifice areas calculated are compared with the results acquired by experiment and flow field simulation. This study has some value for the valve design with complicated orifices and valve noise study . |
