一、电动单座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。
电动平衡笼式调节阀控制各种高温、低温的高压流体，是一种压力平衡式的调节阀。阀结构紧凑，有呈S流 线型的通道.DHCB电动平衡笼式调节阀，控制各种高温、低温的高压流体，是一种压力平衡式的气动调节阀。阀结构紧凑，有呈S流线型的通道，还设有一个改善套筒周围流体平衡流动的导 流翼，使其压降损失小，流量大，可调范围广，流量特性精度高，符合IEC534-1-1976 标准。调节阀的动态稳定性好，噪音低，空化腐蚀小。调节阀的泄漏量符合ANSIB16.1 04标准。
Electric single-seat regulating valve is a kind of pressure balance type regulator. Accept adjusting instruments to dc current signal, change the modulated medium flow, keep accused of process parameters in the given value. Widely used in electric power,
Electric balance cage valve control all kinds of high temperature and low temperature high pressure fluid, is a kind of pressure balance type regulator. Valve structure is compact, in an s-shaped channel flow lines. DHCB electric balance cage valve, high pressure fluid control all kinds of high temperature, low temperature, is a kind of pressure balance type pneumatic control valve. Valve structure is compact, has S streamlined channel, also has an improved balance flow guide sleeve around fluid flow wing, make its loss of the pressure drop is small, large flow, adjustable range and flow characteristic of high precision, IEC534-1-1976 standard. Regulator of dynamic stability, low noise, small cavitation corrosion. Regulating valve leakage ANSIB16.1 04 standards.

三、电动单座调节阀优点
电动单座调节阀是一个新的自力式调节阀种类。相对于手动调节阀，它的优点是能够自动调节;相对于电动调节阀，它的优点是不需要外部动力。应用实践证明，在闭式水循环系统(如热水供暖系统、空调冷冻水系统)中，正确使用这种阀门，可以很方便地实现系统的流量分配;可以实现系统的动态平衡;可以大大简化系统的调试工作;可以稳定泵的工作状态等。
Electric single-seat regulating valve is a new type control valve types themselves. Compared with the manual control valve, its advantage is able to automatically adjust; Relative to the electric control valve, its advantage is not need external motivation. Application practice proved that in a closed water circulation system, such as hot water heating system, air conditioning chilled water system), the proper use of the valve, the flow distribution can be easily implemented system; Can realize the dynamic equilibrium of system; Can greatly simplify the system debugging work; Fix the pump working condition, etc.
四、电动单座调节阀特点
1、可调节范围大，固有可调比为50，流量特性有直线和等百分比。
2、阀体按流体力学原理设计的等截面低流阻流道，额定流量系数增大30%。
3、调节切断型采用软密封结构阀芯，达VI级泄漏标准(零泄漏)。
4、伺服放大器采用深度动态负反馈，可提高自动调节精度。
5、电动操作器有多种形式，可适用于4~20mA。DC或0~10mA.DC。
6、波纹管密封型调节阀对移动的阀杆形成完全的密封，堵绝流体外漏。
7、电子型电动调节阀可直接由电流信号控制阀门开度，无需伺服放大器。
1, wide adjustable range, inherent adjustable ratio of 50, flow characteristic such as straight lines and percentage.
2, the valve body according to the fluid mechanics principle design of cross section, such as low flow resistance of fluid, rated flow coefficient increases by 30%.
3, adjust the cutting type USES the soft sealing structure of valve core, grade VI leakage standard (zero leakage).
4, the depth of the servo amplifier adopts dynamic negative feedback, can automatically adjust the accuracy.
5, electric operator has a variety of forms, can be applied to 4 ~ 20 ma. The DC or 0 ~ 10 ma. DC.
6, bellows seal type regulator for mobile stem form completely sealed, plugging fluid leakage.
7, electrical power regulator can be directly controlled by the current signal valve opening, without the servo amplifier.
