摘要
为了降低负载敏感型多路阀的体积和重量,提出了一种三通流量阀与溢流阀的集成设计方案。文中详细阐述了该集成阀的结构及原理,搭建了其液压仿真模型,并应用于某款工程机械产品的变幅系统,测试验证了其三通分流功能和溢流保护功能。进一步,讨论分析了集成阀的设定压差、阀芯过流孔径等关键参数对系统压损和工作效率有很大的影响,实际使用中需综合两者来选用该阀。
In order to reduce the volume and weight of load sensitive multi-way valve,an integrated design scheme of three-way flow valve and overflow valve is proposed in this paper.The structure and principle of the integrated valve are described in detail,and its hydraulic simulation model is built.It is applied to the luffing system of a construction machinery product,and its three-way shunt function and overflow protection function are tested and verified.Further,it is discussed and analyzed that the key parameters such as the set differential pressure of the integrated valve and the overflow aperture of the valve core have a great impact on the system pressure loss and work efficiency.In practical use,the valve needs to be selected by combining the two factors.
