二、高精度电动伺服针型调节阀(High precision electric servo needle regulating valve)


高压高精度针形调节阀采用高精度文丘里喉道及高精度阀针结构,具有整体系统性能稳定、气体输出端流速平稳、高灵敏度位置反馈、高精度控制、可调比宽等优点。其中,阀门可调比高于1:300,比国内同类产品的1:30提高了10倍,阀门可控分辨率达到0.05%,一般气流量可控制精度达0.3%。
High-pressure and high-precision needle valve adopts high precision Venturi throat and high-precision valve needle structure, which has the advantages of stable overall system performance, smooth flow of gas output, high sensitivity position feedback, high precision control and adjustable ratio. Among them, the valve adjustable ratio can be adjusted higher than 1: 300, compared to the 1:30 that of the similar products in China, which increased by 10 times combined with the valve control resolution of 0.05% and the general air flow control accuracy of 0.3%.
该产品相比全电子系统控制阀、集成箱体等类型控制阀,控制精度高,运行稳定,输入、输出端均采用高压连接法兰方式。不锈钢及性能更优的材质结构外表面,均采取特殊先进的技术处理,外表面整洁美观;该产品是国内首批研制,且国外无同类产品,能替代国外类似产品,市场竞争能力强。
Compared with the full electronic system control valve, the integrated box and other types of control valves, this product has the virtue of high control precision, stable operation, in the reason of that its input and output terminals are high-pressure connection flange. Stainless steel and better performance of the material structure of the outer surface, are taken to special advanced technology. Therefore, the outer surface is neat and beautiful. The product is the first batch of domestic development, and no similar foreign products, which can replace correlative overseas products with strong market competition ability.
该产品进入系列和批量、规模生产后,对产品开发人员、技术人员和制造人员的需求将持续增长,促进当地就业。同时,在国家制造强国战略指导下,高端制造业对此类产品的需求也将持续增长。
When the product starts series, batch, and scale production, product developers, technicians and manufacturing staff demand will continue to grow and local employment will be promoted. At the same time, under the guidance of the national manufacturing strategy, high-end manufacturing demand for such products will experience a sustainable growth as well.
