进口高压电动调节阀概述：
高压电动调节阀是一种压力平衡式的调节阀。接受调节仪表来的直流电流信号，改变被调介质流量，使被控电动单座调节阀(14张)工艺参数保持在给定值。广泛应用于电力、冶金、化工、石油、轻纺、制药、造纸等工业部门的生产自动化控制。
Imported high pressure electric regulator overview:
High voltage electric control valve is a kind of pressure balance type regulator. Accept adjusting instruments to dc current signal, change the modulated medium flow, make charged electric single-seat regulating valve (14) process parameters in a given value. Widely used in electric power, metallurgy, chemical industry, petroleum, textile, pharmaceutical, paper and other industrial sectors of production automation control.
一、进口高压电动调节阀产品特征分类：
流通能力Cv是选择调节阀的主要参数之一，调节阀的流通能力的定义为：当调节阀全开时，阀两端压差为0.1MPa，流体密度为1g/cm3时，每小时流径调节阀的流量数，称为流通能力，也称流量系数，以Cv表示，单位为t/h，液体的Cv值按下式计算。根据流通能力Cv值大小查表，就可以确定调节阀的公称通径DN。调节阀的流量特性，是在阀两端压差保持恒定的条件下，介质流经调节阀的相对流量与它的开度之间关系。调节阀的流量特性有线性特性，等百分比特性及抛物线特性三种。等百分比特性的相对行程和相对流量不成直线关系，在行程的每一点上单位行程变化所引起的流量的变化与此点的流量成正比，流量变化的百分比是相等的。所以它的优点是流量小时，流量变化小，流量大时，则流量变化大，也就是在不同开度上，具有相同的调节精度。线性特性的相对行程和相对流量成直线关系。单位行程的变化所引起的流量变化是不变的。流量大时，流量相对值变化小，流量小时，则流量相对值变化大。
Flow capacity Cv is one of the most important parameters to choose the regulating valve, regulating valve of flow capacity is defined as: when the control valve fully open, on both ends of the valve differential pressure is 0.1 MPa, the fluid density is 1 g/cm3, the regulator on the number of traffic flow diameter per hour, called flow capacity, also known as the flow coefficient, expressed as a Cv, unit for t/h, Cv value of the liquid press type calculation. According to the flow capacity Cv value look-up table size, you can determine the nominal size of the regulating valve DN. Regulating valve flow characteristic, it is on both ends of the valve differential pressure under the condition of constant, medium flows through the regulator of the relation between relative flow and its opening. Regulating valve the flow characteristic of linear features, such as percentage and parabolic characteristics of three. Percentage characteristics such as relative trip and no linear relationship between relative flow in the process of every point unit running change caused by the flow of change is proportional to the flow of this point, the percentage of the flow rate change is equal. So it has the advantage of traffic hours, changing flow is small, large flow, the flow rate change is big, is also on the different opening, has the same accuracy. Linear characteristic of relative stroke and the relative flow into a linear relationship. Unit trip caused by the changes in the flow rate change is constant. Large flow, the flow relative changes little, traffic hours, flow relative change is big.
