  可能大家对智能阀门定位器的了解不是很多,但是那也没有关系,让小编来给大家介绍一下,看看是怎么进行区分的,我们一起来看看本章的所有内容。

  控制信号增加,使阀杆下行的为正作用,使阀杆上行的为反作用。阀门定位器是控制阀的主要附件,通常与气动控制阀一起使用。然后气动控制阀由其输出信号控制,控制阀移动后通过机械装置将阀杆的位移反馈给阀门定位器。阀门位置状态通过电信号码传送到上层系统。

  智能阀门定位器不需要手动调节,可自动检测调节阀零点、全量程、摩擦系数,并自动设定阀门定位器的控制参数。阀的开度(阀杆行程)是信号压力和弹簧力组合的结果。理论上,阀杆的位置应该是信号压力和弹簧力之间的平衡。

  然而,在实际工作中会有其他的作用力,主要是阀杆的摩擦力和介质对阀芯的推力。这使得阀门的开启与理论位置不一致,阀门定位器可以看作是以控制信号为给定值的伺服控制系统,以阀杆位移的机械反馈为测量值,使调节阀的开启和控制信号保持相应的功能关系,所以以上就是小编要给大家介绍的区分,希望能给大家带来帮助。

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.
