大型机械的液压系统由于流量较大等特点,采用插装阀(又称锥阀)愈来愈显示出其独特的优越性。随着机械控制功能的不断完善,插装阀液压系统也日趋复杂。但目前对插装阀液压系统的图解还沿用一般的表示法,其层次不很清楚。本文提出一种液阻桥路图解分析法,它不仅适用于液压控制系统及传动系统,而对大流量的插装阀液压系统 Large-scale mechanical hydraulic system due to the larger flow characteristics, the use of cartridge valve (also known as cone valve) has increasingly shown its unique advantages. With the continuous improvement of mechanical control functions, cartridge valve hydraulic system is also increasingly complicated. But at present, the illustration of the hydraulic system of the cartridge valve also follows the general notation, and its level is not very clear. This paper presents a schematic diagram of the hydraulic bridge, which not only applies to the hydraulic control system and transmission system, and the flow of the cartridge valve hydraulic system
