摘要
本文在分析了插装阀液压系统特点的基础上，提出了一种基于通路拓扑的插装阀液压系统原理图设计模板，介绍了基于该设计模板的插装阀液压原理图CAD系统HGHSCAD的体系结构和工作流程，最后在总结分析的基础上得出了一些有益的结论。
In this paper, a global model (palette ) which can include all kinds of logic valve hydraulic systems and canbe easily dealt by computer is presented on the base of analyzing the characteristics of logic valve hydraulic system. Thenthe system structure of a logic valve CAD Software based on the previous global model is introduced, some valuableconclusions are obtained at last.
