摘　　要：提出了基于可拓工程方法的阀门概念设计方法,并将其应用于球阀的方案设计。先采用发散树方法的一般模式发散出各种球阀设计方案,再根据已知特征值找出满足要求的初选方案,最终采用优度评价法选取较优方案。Based on the extension engineering method, the method of the conceptual design of valves is proposed, and this method is in application to the ball-valve schemes＇ design. At first, the general mode of the divergent tree method is utilized to gain several of schemes of the ball-valve. Then qualified schemes are selected preliminarily according to the known characters＇ value. Finally, the most excellent one is selected by the optimal appraisal method.
