(Reporter Xu Qi-min) set of magnetic technology in an electro-hydraulic servo system, manufacturing level, is a measure of the level of national industrial automation a sign, and our long-term servo valve manufacturing industry remained at the low-end market. Recently, this situation has changed - from CSIC's seventh 〇 4 Institute was informed by decades of painstaking research and development of the jet pipe electrohydraulic servo valve and implementation of industrialization, through the efforts, and now finally shake the foreign brands the monopoly of the domestic Check Valves high-end market. The servo valve of large equipment, like motor neurons, can the "brain" came the directive into hydraulic power, driving the machine to make the appropriate action. Satellite launched solar panels, a huge robotic arm lift lines, long wheel drive tons of ocean, all without it. To create "Accuracy is king," the jet-pipe servo valve, you need a higher level of technology - a lot of core components of the processing must be magnifying glass, microscope, the error can only be less than 1 micron. Since 1985, the first in the country to produce a jet pipe servo valve 704 in this area have continued to explore and accumulate. But when small quantities of "lab to create" large quantities into the "assembly line to create" quality control has become a big problem. In response to this situation, Butterfly Valves researchers starting in 2006, technical research, establish a series of quality control system. To date, the Institute researchers have developed out of six series, more than 60 specifications of the jet pipe servo valve, while the product failure rate from the original more than 30% to 3% or less. 704 electro-hydraulic servo valve industry, by director Wong told reporters that at present they have accumulated up to 0.08-micron precision detection and measurement capabilities, developed a sophisticated car, precision grinding, micro-processing capabilities. When the 704 high-quality jet-pipe servo valve to the market, Reducing Valves foreign firms are forced to lower prices of similar products by half, while shortening lead times and enhance service quality. Recently, Huang Zeng introduction, after a successful first step, they challenge the new height: the development of the world's most next-generation digital servo valve, while strengthening the quality system, servo valve to spend to fight for domestic aircraft, spacecraft.

本报讯（记者许琦敏）集机电液磁技术于一身的伺服系统的制造水平，是衡量国家工业自动化水平高低的一个标志，而我国的伺服阀制造业长期徘徊在低端市场。最近，这一情况有了改观——记者从中船重工第七〇四研究所获悉，该所几十年潜心研发射流管电液伺服阀并实施产业化，经过努力，如今终于撼动了国外品牌对国内高端市场的垄断。　　大型装备中的伺服阀好比运动神经元，能将“大脑”传来的指令，转化成液压动力，驱动机器做出相应的动作。卫星展开太阳能电池板、生产线抬起巨大的机械臂、万吨巨轮远驶大洋，都离不开它。　　制造“精度为王”的射流管伺服阀，则需要更高水平的技术——不少核心器件的加工，必须在放大镜、显微镜下进行，误差只能小于1微米。自1985 年在国内生产出第一个射流管伺服阀，七〇四所就不断在这个领域中探索、积累。可当小批量的“实验室制造”转变为大批量的“流水线制造”，质量控制却成了大问题。针对这一情况，科研人员从2006年开始了技术攻关，建立了一系列质控体系。　　迄今为止，该所科研人员已研发出了6个系列、60多个规格的射流管伺服阀，同时将产品故障率从原先的超过30%降到了3%以下。七〇四所电液伺服阀产业部主任黄增告诉记者，目前他们已拥有了精度高达0.08微米的检测能力和计量能力，发展出了精密车、精密磨、微孔加工等能力。　　当七〇四所的高质量射流管伺服阀推向市场后，国外厂商被迫将同类产品价格下降了一半，同时缩短了供货周期，提升售后服务质量。最近，黄增介绍，在成功迈出第一步后，他们又挑战新的高度：开发世界上最新一代的数字伺服阀，同时加强质量体系建设，争取将国产伺服阀用上飞机、飞船。
