BURKERT气动阀001248中秋节*
德国宝德BURKERT阀门定位器(又称:气动阀门定位器)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。德国宝德BURKERT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。德国宝德BURKERT阀门定位器的作用(1)用于对调节质量要求高的重要调节系统,以提高调节阀的定位及可靠性。(2)用于阀门两端压差大( △p>1MPa)的场合。通过提高气源压力增大执行机构的输出力,以克服液体对阀芯产生的不平衡力,减小行程误差。 (3)当被调介质为高温、高压、低温、有毒、易燃、易爆时,为了防止对外泄漏,往往将填料压得很紧,因此阀杆与填料间的摩擦力较大,此时用定位器可克服时滞。
