摘　　要：平衡阀是液压起重机械中的一个重要元件,针对现有平衡阀存在的问题,提出了基于负载敏感的平衡阀,介绍了其工作原理及结构特点,建立了平衡阀的动态数学模型,借助MATLAB/Simulink进行了数字仿真。研究表明该阀的导控压力为定值,不随负载变化,节能、稳定性好。Balancing valve has been playing a key role in crane mechanics. In order to solve the problems in traditional balancing valve, a new type load-sensing balancing valve is put forward. The valve, of which the structure and working principle have been described and its static and dynamic characteristics been analysed, has been indicated by Matlab/Simulink simulation with lower controlling pressure and higher stable performance than traditional balancing valve which produces higher energy loss.
