进口自力式压差控制阀

英国Regus雷格斯进口自力式压差控制阀

自力式压差控制阀不需外来能源依靠被控介质自身压力变化进行自动调节,自动消除管网的剩余压头及压力波动引起的流量偏差恒定用户进出口压差,有助于稳定系统运行,特别适用分户计量或自动控制系统中。

英国Regus雷格斯进口自力式压差控制阀的定义

压差控制阀一般安装在用户入口回水管上,阀下导压管与入口处供水管相接,P1为供水压力,P2为阀内回水压力,P3为阀外回水压力。

设阀内系统压差△Pi(△Pi=P1-P2)为阀门压差设定值时,阀门下膜室压力P1与P2加上弹簧被压缩变形产生的推力相平衡,从而确定了流体流过阀门的流通截面积A和流量系数。当流量改变时,上述力的平衡使阀门的流通截面积A和流量系数发生变化,但△Pi保持不变。

△P=Kqm2

K-------管路阻抗;

qm----流量。

由上式可知管路阻力与质量流量的二次方及管路阻抗成正比。当流量变化时使上膜室压力P2变化导致阀芯上下移动,使A及相应的流量系数均改变来调整阀内系统总阻力的变化,使△Pi基本保持不变。
