电站调节阀

电站调节阀】是调节阀旗下产品,我们可为客户提供相关电站调节阀、标准、作用、结构图、规格、型号、外形尺寸、工作原理、说明书、欢迎来电咨询、采购。

  电站调节阀由电动执行机构和阀体两部分组成,电动调节阀输入是调节器送来的直流电信号,经伺服放大器放大后来驱动执行机构,产生轴向推力,带动调节阀动作,从而引起介质流量的变化,来调节系统中各类参数。同时执行机构发出一个阀的位置信号供伺服放大器比较,使调节阀始终保持在一个输入信号相对应的位置上,完成伺服调节任务。

  The Power Station Control Valve Consists Of An Electric Actuator And A Valve Body. The Input Of The Electric Control Valve Is The Dc Electric Signal Sent By The Regulator. After Being Amplified By The Servo Amplifier, The Actuator Is Driven To Generate Axial Thrust, Which Drives The Regulating Valve To Act, Thus Causing The Change Of Medium Flow To Adjust Various Parameters In The System. At The Same Time, The Actuator Sends A Valve Position Signal For The Servo Amplifier To Compare, So That The Control Valve Is Always In A Position Corresponding To The Input Signal To Complete The Servo Regulation Task.
