YT-1000定位器

◆ 定位器:YT-1000R,YT-1000L,YT-1200R,YT-1200L


◆ 概述:

阀门定位器,按结构分气动阀门定位器、电-气阀门定位器及智能阀门定位器,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。


◆ 工作原理:

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,建立了阀杆位移量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。


◆ 适配品种:

常用执行机构分气动执行机构,电动执行机构,有直行程、角行程之分。用以自动、手动开闭各类阀门、风板等。

Products and services that meet fluid control requirements

Each process, facility, and environmental constraint has its own special requirements. Therefore, Kinko offers a comprehensive range of products that include different performance levels, pressures, functions, and materials.

Product application scope

These devices are suitable for accurately controlling media such as gases, liquids, steam, etc., and maintaining process parameters such as pressure, flow rate, temperature, and liquid level at given values. Especially suitable for work environments where the allowable pressure difference is small and the allowable leakage is also small, and the pressure difference is not significant.
