ABSTRACT

In this study, Solidworks software was used to calculate and analyze the stress and strain of the valve port of the ball valve, and the numerical characteristics of the stress, strain and displacement of the ball valve were preliminarily estimated. The results of this study will provide a good basis for further research on numerical characteristics of ball valve at different positions. By studying the preliminary findings of ball valve in the fully open and fully closed in both cases, the stress, strain and displacement of the valve port suffered under the grid as a variable stress change with the increase of grid number , strain and displacement data in the grid number increase after the change is small, the material is a greater difference between the values of maximum stress under variable, while the smallest stress value were similar, strain and displacement of maximum minimum value difference is not large, in the variable for the load stress and strain when the maximum and the minimum and maximum displacement and load force has a positive correlation. The minimum displacement value does not increase with the increase of the loading force, and remains unchanged.
