　       国际上调节阀技术发展到现在，其结构、材料等技术已经非常成熟，在这方面几乎没有很大的进展，于是调节阀的发展方朝向何处？疏水阀成了国际阀门界探讨的问题，最近，美国费希尔公司研制出一种计量调节阀，它是在原有1098系列自力式调压阀的基础上改进成功的。 所谓计量调节阀就是：流经阀门介质的压力、电动执行器温度、流量、开度参数可以现场显示、远传、并有网络接口，还有故障报警等，集这些功能于阀门一身，主要供远程调度监控使用。 在顶盖有一个位移传感器与阀瓣连接，可以感知精确的开度，通过阀门进出口两个压力传感器测出压差，由阀门的流量系数间接的换算出流量，特殊阀门2003年刚刚推出此产品时，流量误差在5%，不能作为贸易计量使用，到今年又推出的改进产品其流量误差达到1%。 我国阀门设计制造在结构、工艺、材料等方面与国际上相差很多，衬里阀门但是在新技术方面也可以迎头赶上，从上例可以看出，流量功能只不过把阀门本身当成电磁阀一个压差（孔板）式流量计，各种传感器技术、单片机技术在我国也比较成熟，其实我们也可以造出这种阀门，但是美国人想到了前面。您有什么感想？

       International control valve technology to now, its structure, materials technology has been very mature in this respect very little progress, so control valve toward the development of sidePLUG VALVES Where? Become a problem of the international valve industry, most recently, the U.S. Fisher developed a metering valve, which is the original 1098 series of self-operated pressure regulator on the basis of improved success. The so-called metering valve is:REDUCING VALVES flow through the valve of pressure, temperature, flow, opening arguments could live show, Remote, and a network interface, as well as fault alarm, set these features on the valve 1,SAFETY VALVES mainly for remote schedule to monitor the use. In the roof there is a displacement sensor connected with the valve flap, the opening can be accurately perceived, both import and export through the valve pressure sensors measure the pressure, the valve flow coefficient of conversion of the flow of indirect, hasMULTI-FUNCTIONAL WATER PUMP CONTROL VALVE just launched the 2003 product, the flow error of 5%, not as a trade measure used to improve products introduced this year and its flow rate error of 1%. Valve design and manufacturing in China in the structure, processes, materials and so much difference with theMUD VALVES international community, but new technology can also be caught up and can be seen from the above example, flow features only to itself as a pressure valve (orifice ) flow meter, a variety of sensor technology, single chip technology is relatively mature in China, in fact, we could fabricate such a valve, but the Americans thought of before. What do you think?
