阀门定位器工作原理讲解

(Summary description)随着智能仪表技术的发展,微电子技术广泛应用在传统仪表中,大大提高了仪表的功能与性能。阀门定位器是调节阀的主要附件,通常与气动调节阀配套使用,它接受调节器的输出信号,然后以它的输出信号去控制气动调节阀,当调节阀动作后,阀杆的位移又通过机械装置反馈到阀门定位器,阀位状况通过电信号传给上位系统。

  随着智能仪表技术的发展,微电子技术广泛应用在传统仪表中,大大提高了仪表的功能与性能。阀门定位器是调节阀的主要附件,通常与气动调节阀配套使用,它接受调节器的输出信号,然后以它的输出信号去控制气动调节阀,当调节阀动作后,阀杆的位移又通过机械装置反馈到阀门定位器,阀位状况通过电信号传给上位系统。
  定位器根据工作原理可分为:气动定位器、电气式定位器、智能式定位器
  电气阀门定位器工作原理。电气阀门定位器是控制阀的主要附件。它将阀杆位移信号作为输入的反馈测量信号,以控制器输出信号作为设定信号,进行比较,当两者有偏差时,改变其到执行机构的输出信号,使执行机构动作,建立了阀杆位移倍与控制器输出信号之间的一一对应关系。因此,阀门定位器组成以阀杆位移为测量信号,以控制器输出为设定信号的反馈控制系统。该控制系统的操纵变量是阀门定位器去执行机构的输出信号。
  阀门定位器如何选择?我们专注于电子备件产品的销售和解决方案的服务,产品涉及工业自动化、过程自动化、电力自动化,尤其是停产仅作为备件、以旧换新、稀缺、非标、订制特制备件产品的销售,针对广大客户的需要,公司备有大量现货。

The working principle of valve positioner

Under the advancement of technology, we have developed a valve positioner to control the equipment in order to work more accurately. The valve positioner can be used in conjunction with various equipment. Using the valve positioner, we can understand a signal of the adjustment output in the equipment, so as to realize the control of the equipment. Although the use of valve positioners is very common in our lives, many people do not know much about the structure and working principle of valve positioners. Let's take a look at the working principle of the valve positioner together.
