| Abstract: | Floating ball valve with the structure and performance are briefly introducedand the fluid supply system, fault reason and mechanism of valve failure occurring. ANSYS Workbench platform to build models based on job characteristics, on the basis of the valve, on the sphere and the left valve body valve fatigue life in different loads were simulated and analyzed ,obtain the valve ball and the left valve body deformation, stress concentration and fatigue damage size and location, and with the actual usage of the comparison and verification of the valve. Put forward the method to improvethe measures and extend valve life. |
