流量调节阀又名自力式流量控制阀，流量平衡阀，静态平衡阀，它是一种直观简便的流量调节控制装置，管网中应用流量调节阀可直接根据设计来设定流量，阀门可在水作用下，自动消除管线的剩余压头及压力波动所引起的流量偏差，无论系统压力怎样变化均保持设定流量不变，该阀这些功能使管网流量调节一次完成，把调网工作变为简单的流量分配，有效的解决管网的水力失调。

流量控制阀用来控制执行机构的速度。按其功能和用途，可分为节流阀、行程节流阀、调速阀和分流一集节流阀等。它们的共同特点是利用改变阀中的节流口的过流面积，来调节油液流过节流口时的液阻大小，从而实现对流量的控制。

流量调节阀的工作原理：

数显流量调节阀其结构是由自动阀芯，手动阀芯及显示器部分组成。显示部分则由流量阀机芯、传感器发讯器、电子计算器显示器部分组成。被测水流经阀门，水流冲击流量机芯内的叶轮，叶轮旋转与传感发讯器感应，使传感器发出与流量成正比的电讯号，流量电讯号通过导线送入电子计算器，经过计算器计算、微处理器处理后，其流量值显示出来。

自力式流量控制阀是一种依靠流经阀内介质自身的压力驱动阀门自动控制流量的阀。基本原理是流体经过阀门时，在阀内的节流元件（如设定阀门）两端会产生压力差，流量越大压差越大。利用这个压差来驱动主阀阀瓣，使得压差越大阀瓣开度越小。从而达到控制流量的目的。

流量调节阀的作用：

1、节流阀：在调定节流口面积后，能使载荷压力变化不大和运动均匀性要求不高的执行元件的运动速度基本上保持稳定。

2、调速阀：在载荷压力变化时能保持节流阀的进出口压差为定值。这样，在节流口面积调定以后，不论载荷压力如何变化，调速阀都能保持通过节流阀的流量不变，从而使执行元件的运动速度稳定。

3、分流阀：不论载荷大小，能使同一油源的两个执行元件得到相等流量的为等量分流阀或同步阀；得到按比例分配流量的为比例分流阀。

4、集流阀：作用与分流阀相反，使流入集流阀的流量按比例分配。

5、分流集流阀：兼具分流阀和集流阀两种功能。

2FRM 型流量控制阀是一种二通流量控制阀。它们用于保持流量稳定，通常不受压力和温度的影响。

通常，阀由壳体、节流孔衬套、带有可选行程限制 的压力补偿器、单向阀、型号 2FRM 中的调节元件及齿轮活塞传动装置和方向阀组成。从通道 A 到通道 B 的流量在节流点处节流。在型号 2FRM 中，节流剖面可通过机械转动调节元件上的曲线螺栓进行设置。速率可通过单向节流阀进行设置。为固定所需的调节范围，在齿轮活塞传动装置的两侧配备可调行程限制。含有上游压力补偿器，以确保流量在节流点处不受压力影响且保持稳定。

由于节流点采用了节流孔设计，因此不会受到温度的影响。

通过单向阀实现从通道 B 到通道 A 的自由回流。

调节流量只能从通道 A 流向 B。

为了在两个方向上控制流量，可在流量控制阀下安装一个 Z4S 型整流器叠加阀板。

调节阀流量特性选择

1、流量特性

调节阀的流量特性是指被调介质流过调节阀的相对流量与调节阀的相对开度之间的关系。其数学表达式为

式中：Qmax--调节阀全开时流量，mm3/s

L----调节阀某一开度的行程，mm

Lmax--调节阀全开时行程，mm

调节阀的流量特性包括理想流量特性和工作流量特性。理想流量特性是指在调节阀进出口压差固定不变情况下的流量特性有直线、等百分比、抛物线及快开4种特性。

（1）直线性质：调节阀的相对流量与相对开度呈直线关系，即单位相对行程变化引起的相对流量变化是一个常数。

特点：①小开度时，流量变化大，而大开度时流量变化小；

②小负荷时，调节性能过于灵敏而产生振荡，大负荷时调节迟缓而不及时；

③适应能力较差。

（2）等百分比性质：单位相对行程的变化引起的相对流量变化与此点的相对流量成正比。

特点：①单位行程变化引起流量变化的百分率是相等的；

②在全行程范围内工作都较平稳，尤其在大开度时，放大倍数也大，工作更为灵敏有效；

③应用广泛，适应性强。

（3）抛物线性质特性介于直线特性和等百分比特性之间，使用上常以等百分比特性代之。

特点：①特性介于直线特性与等百分比特性之间；

②调节性能较理想但阀瓣加工较困难。

（4）快开性质：在阀行程较小时，流量就有比较大的增加，很快达*。

特点：①在小开度时流量已很大，随着行程的加大，流量很快达到*；

②一般用于双位调节和程序控制。

在实际系统中，阀门两侧的压力降并不是恒定的，使其发生变化的原因主要有两个方面。一方面，由于泵的特性，当系统流量减小时由泵产生的系统压力增加。另一方面，当流量减小时，盘管上的阻力也减小，导致较大的泵压加于阀门。因此调节阀进出口的压差通常是变化的，在这种情况下，调节阀相对流量与相对开度之间的关系。称为工作流量特性。具体可分为串联管道时的工作流量特性和并联管道时的工作流量特性。
