畢業(yè)設(shè)計(jì)說明書中文摘要
本文通過對球閥結(jié)構(gòu)的分析，先后計(jì)算了球體直徑，密封比壓，密封力，轉(zhuǎn)矩，并且通過對閥桿強(qiáng)度的計(jì)算以及球體和閥座的設(shè)計(jì)，較為全面的設(shè)計(jì)和確定和球閥的零件尺寸和材料，并通過Pro/e軟件對圖形進(jìn)行建模，使用SolidWorks Simulation軟件對閥體進(jìn)行了簡單的應(yīng)力分析，最終完成了本篇設(shè)計(jì)。

title A design of liquid ball valve


Abstract
Through the analysis of the structure of ball valve this paper has calculated the sphere diameter sealing pressure sealing force torque. With the calculation of strength of the stem and the design of ball and seat The size and materials of ball valve parts are designed and determined. The Pro/e software makes great contribution to the graphic modeling. SolidWorks software has been used to make body stress analysis. With all these work done the design is completed finally..


Keywords Structure design; Strength check; Stress analysis; Energy agency
