Chapter 4 firstly analyses the generation mechanics, calculating method and interference effect of flow force in the outflowing large-capacity proportional valve. Then it not only presents a structural design to compensate the flow force according to the performance characteristic of the cone valve, but also calculates and simulates the flow field at the valve port through CFD software Fluent6.0. At last it studies the influence of compensation structure parameters and obtains better projected dimensions.

第四章主要阐述了电液大流量控制阀的液动力产生机理，计算及其对系统的干扰作用，在此基础上针对该阀的结构和工作特点提出阀芯所受液动力的补偿方法和结构，然后对阀口处的流场进行了有限元仿真计算，探索了液动力大小与补偿结构的各参数之间的关系，最后得出能实现液动力补偿的合理结构。
