摘　　要：软质材料通常采取压缩包装的形式进行储存和运输,该研究设计了一种基于插装阀的软质材料压缩包装的液压回路,该回路可以实现空行程快速下降、压缩时正常速度下降、捆扎时低速下降、捆扎完毕后快速上升的功能,并且在活塞杆和压头停止运动时能够保压。对插装阀的阀块进行了有限元分析,结果显示阀块满足结构强度要求。所设计的液压回路已经应用在纤维的压缩包装中,效果良好。Soft materials are usually compressed and baled for store and transport. A hydraulic circuit based on cartridge valve is designed to compress and bale soft materials. By this circuit, to fall quickly in idle, normally in compression, slowly in binding and to rise quickly in return can be achieved. The oil pressure can be maintained when the piston is in halt. The block of cartridge valve is analyzed by the finite element method （FEM） and the results show that the structure intensity meets the requirements. The circuit has been applied to the compression of fibers and the system runs well.
