摘　　要：针对目前换向阀存在体积大,需借助外力工作及实时性差等缺点,设计了一种基于流体压力的新型二位三通自动换向阀。借助流体仿真软件Fluent仿真该换向阀在最大开度时,边界及出口处流体流动速度分布。仿真结果分析表明,该阀门流场流动稳定、设计合理、外观小巧、实时性好,为阀门的进一步优化设计提供依据。In view of the disadvantages of large volume, working by external force and poor real - time performance, a new type of two - position and three - way automatic reversing valve based on fluid pressure is designed. The fluid simulation software Fliuent is used to simulate the valve in the maximum opening, and obtain the velocity distribution of fluid flow at boundary and exit. The simulation results show that the flow stability of the valve flow field, reasonable design, compact appearance, good real - time performance. The basis for the further optimization design of valve is provided.
