摘　　要：液压阀是控制工程机械行动与工作的关键元件。由于工程机械结构复杂、工作条件恶劣、工作环境和工作介质多变,每年发生故障失效的液压阀数量巨大。这些失效的液压阀往往被当作废品进行回炉再利用,其中的附加值绝大部分被浪费掉,同时消耗大量资源。再制造产业的日益成熟可以有效的解决这一问题。通过回收大量失效的液压阀,利用专业化的处理方式对其进行批量化修复、性能升级,使得失效的液压阀恢复原有的性能。文章对工程机械液压阀的失效模式以及再制造工艺流程进行了介绍,并对再制造液压阀的经济效益、资源效益和环境效益三方面进行深入分析。结果表明,工程机械再制造液压阀不仅可以恢复原产品的质量和性能,缩短生产周期,并且能够节约成本55%,节能85%,节材90%。The hydraulic valve is the key part of controlling the movement and working of construction ma- chinery. A large number of hydraulic valves lose efficacy every year because of the complex mechanism of con- struction machinery, bad working conditions and changeable objects. These invalid hydraulic valves were mel- ted down in the oven and then reused. However, the additional value of valves is wasted, and it will consume a lot of resources. The remanufacturing industry, which is becoming increasingly mature, can solve this prob- lem. The hydraulic valve can be remanufactured by recollection using professional technology. The failure modes and remanufacturing process of the hydraulic valve were introduced, and the benefits of economy, re- sources and environment were analyzed. The results show that remanufacturing can restore the function of the invalid hydraulic valve and shorten the production cycle. It also can save costs by 55%, save resources by 85%, and save material by 90%.
