             从20世纪初到现在的近百年时间里，调节阀还处于第一代产品的水平上。其特征是：①以20世纪六七十年代水平的单座阀、双座阀、套筒阀为主导产品；②这代产品功能不齐全，不得不依靠扩充产品品种、变型来适应各种不同的场合，过滤器造成了品种规格繁多，对调节阀使用、计算、选型、调校、维护、备件等要求特别高；③可靠性差，使用时出现的问题多；④十分笨重。

　　现今，比较盛行的CV3000、精小型阀与传统老产品相比多了三个30%：重量下降30%；高度下降30%；流量系数提高30%。但它们没带来质的突破，蝶阀只是对传统产品作了改进而已。　　第二代产品从可靠性、功能、重量上应有质的突破。其特征是：①全功能超轻型调节阀代替了众多可靠性差、功能不齐全、又十分笨重的产品，疏水阀代替了第一代的主导产品单座阀、双座阀、套筒阀，成为第二代主导产品；②电子式电动全功能超轻型调节阀逐步取代传统的因原执行机构可靠性差，不得不采用的“气动阀+电气阀门定位器+气源”的组合方式。 　　从外观上看，第二代产品应具备轻型化、小型化、仪表化的特征。

 　　其突出特征是智能化，并满足现场总线的要求，调节阀 在应用上的特点是：①与计算机接口；②自诊断使可靠性更加提高，故障率进一步下降；③改良阀的特性曲线，从而改变阀的调节品质；转子泵④调节阀的品种以及对调节阀的使用要求进一步的简化；⑤指标上，满足现代工业要求达到新的性能水平，例如一些工业部门推出的新的流程与系统对调节阀提出的一些苛刻的要求。 　　第三代调节阀具备的特征　　其突出特征是智能化，并满足现场总线的要求，眼镜阀在应用上的特点是：①与计算机接口；②自诊断使可靠性更加提高，故障率进一步下降；③改良阀的特性曲线，从而改变阀的调节品质；④调节阀的品种以及对调节阀的使用要求进一步的简化；⑤指标上，满足现代工业要求达到新的性能水平，例如一些工业部门推出的新的流程与系统对调节阀提出的一些苛刻的要求。

           From the early 20th century, now nearly a hundred years time, the control valve is still in the first generation level. The features are: ① to the level of the sixties and seventies of the 20th century single-seat valves, seat valves, sleeve valves as the leading product; ② generation product is not complete and had to rely on expansion of product varieties, forms to suit different occasions, resulting in manyForged Steel Valves varieties and specifications, on the control valve to use, calculate, selection, calibration, maintenance, spare parts for special high; ③ poor reliability, multi-use problems; ④ very heavy. Today, the prevailing CV3000, fine old tradition of small valves with more than three compared to 30%: weight decreased by 30%; height decreased 30%; discharge coefficient increased by 30%. But they did not bring a qualitative breakthrough, but it was improved on the traditional products. The second generation of productsWater Control valves from the reliability, function, weight should be a qualitative breakthrough. The features are: ① full-featured ultra-light control valve instead of a number of poor reliability, functionality is not complete, but also very heavy products, instead of the first generation of leading products single-seat valve, double seat valve, sleeve valve, a second-generation The main products; ② Electronic full-function ultra-light electric control valve to gradually replace the traditional low reliability because of the original executive body, had adopted a "pneumatic valve positioner valve + electric + gas source" of the combination. Forged Steel Valves From the exterior view, the second generation should have the light, miniaturization, instrumentation characteristics. Its outstanding feature is the intelligent, and meet the requirements of the fieldbus in the application's features are: ① with the computer interface; ② self-diagnosis to increase reliability even more, the failure rate to decline further; ③ improved valve characteristic Cast Steel curve, thereby changing the valve quality regulation; rotor pump control valve ④ varieties and the use requirements of the regulating valve further simplified; ⑤ indicators to meet the requirements of modern industry to reach a new level of performance, such as some industry's new process and system control valve raised a number of stringent requirements. With the third generation of the characteristics of control valve The outstanding feature is the intelligent, Other pumpsand meet the requirements of field bus, the application features: ① with the computer interface; ② self-diagnosis so that the reliability of increasingly risen, and the failure rate further decreased; ③ Gailiang valve characteristic curve, thereby changing the valve quality regulation; ④ species control valve and the valve further simplify the use of requirements; ⑤ indicators to meet the requirements of modern industry to reach a new level of performance, such as some industrial sectors introduced new processes and systems put forward by regulating valve a number of stringent requirements.
