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。
The conceptual design method of valve based on extension engineering method was put forward and applied to the design of ball valve. First use the general model of divergent tree method to emit a variety of ball valve design scheme, and then find out the primaries according to the known eigenvalue to meet the requirements, and finally use the excellent evaluation method to select the optimal scheme.
