The analysis of automatic regulating system of liquid level of regulating valve
The author: Time:2021/2/24

        从液面调节的观点出发,可用流入量qv1或流出量qve作为调节量。采用哪一个作为调节量,要根据容器的工艺条件来确定。
        给出液面调节的两个可能性:①实线表示控制输入;②虚线表示控制输出。罐中的液面高度z的信号,由变送器TL传送给调节器C0液面输出值与给定值z1在调节器C中比较,调节器输出信号xe,作用于调节阀RR。当液面增高时,流量qv1减少;相反,当液面下降时,流量qv1增加。当以流出量qve作为调节量时,指令正好相反。
        关于液面自动调节系统必须作下列说明:当qve作为调节量时,流出量qve构成主要干扰;相反,以qve作为调节量时,流入量qv1构成主要干扰。
