三、多喷管组合控制阀(Multi - nozzle Combined Control Valve)


该产品属于我公司自主开发,采用二进制权值喷管及驱动阀组合构成,数字量驱动操作,具有响应快、控制精度高、控制范围宽等优点。其中,在高压应用场合气流流量控制精度达1g/s,流量控制范围极高。
The product belongs to our company's independent development. By applying binary weight nozzle and drive valve combination, digital drive operation, it has the advantages of fast response, high control precision, wide control range and so on. In addition, in high pressure applications, the flow rate control accuracy is up to 1g/s, so that flow control range is very high.
该产品采用全电子系统控制,不锈钢结构,高压法兰连接方式,外表面整洁美观,是国内首批研制。与国外同类产品相比,对二进制权值冗余做了深度优化,克服了进位跳变等组合阀缺点,性能更稳定,完全能替代国外同类产品,高端市场竞争能力强。
The product adopts the fully electronic system control, stainless steel structure, high pressure flange connection, which is the first batch of domestic development. By doing so, the outer surface is clean and beautiful. Compared with the similar products abroad, the binary weight redundancy has been optimized in depth, overcoming the shortcomings of the combination valve such as the carry-over jump. What’s more, the performance is more stable, and it can replace the foreign similar products completely. Therefore, its high-end market competition ability is strong.
该产品特别适用于高精度气流压力及流量控制的高端科研生产领域,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。
The product is particularly suitable for high-end scientific research and production areas of high-precision air pressure and flow control . When it into the series and volume, scale production, product developers, technicians and manufacturing staff demand will continue to grow and local employment will be promoted accordingly.
