压力调节阀亦称自力式平衡阀、流量控制阀、流量控制器、动态平衡阀、流量平衡阀，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。流量调节阀主要应用于：集中供热（冷）等水系统中，使管网流量按需分配，消除水系统水力失调，解决冷热不均问题。
压力调节阀工作原理：
通过接收工业自动化控制系统的信号（如：4~20ma）来驱动阀门改变阀芯和阀座之间的截面积大小控制管道介质的流量、温度、压力等工艺参数。实现自动化调节功能
由于气动调节阀具有本质防爆、性能可靠等优点，国内外调节阀仍以气动为主。
过去，国内正式生产的小流量调节阀。 高使用压力可达100公斤/厘米 2 ，额定的流通能力c 值可以 从0.05 到0.0012。其阀座孔径为3毫米，阀芯为圆柱形，上面刻有一道或数道v 型槽 ，阀杆行程6毫米，阀门 无配套 的定位器，因此控制精度较差。

我国也引进了小流量调节阀。流通能力约为0.001，阀芯为带有缺口的圆柱形。工作压力为300公斤/厘米 2 阀杆行程7/16英寸，阀芯为圆锥形，该阀门带有摩尔公司 的顶装定位器。
上述这类阀门的特点是结构简单，重量轻。常用的阀座孔径为1/8～1/4英寸(约为3.175a-6.35 毫米)，阀杆行程为1/4～l/2英寸(合6.35～12.7 毫米)。这类阀门的流量能力 小可以做到0.00006，以至更小。
一般地说，圆柱开槽型的阀芯，在特性化方面比圆锥形好，它可以通过改变 槽深来获得 设计特性，但后者调节可*性好，因为通过阀门的流体，分布在阀芯截面的整个圆周上。这种阀门常用在精度要求不很高的场合。但容量精度和特性的重现性较差。
阀门流通能力，主要取决于流孔直径，对于一个1/16英寸的流孔，理论上的 cv 值约为0·06，或者说只是接近小流量的上限。要进～步减小流量，必须从根本上减小阀芯的行程或约束流孔 的开度
解决气蚀问题应从求避免气蚀的方法和耐气蚀 的材料着手，避免气蚀的方法有几种。
1、改进阀芯，阀座设计，使其具有合理的液流速度分布和压力分布。如小流量调节阀采用狭长通道式阀芯、阀座。阀芯、阀座孔都有很小的锥度，适用于在恒定的上游压力条件下地控制流量。由于这种 结构具确吸收 能量，减小气蚀的功能，据资料报导，它曾用于4200公斤/厘米 2 的压降下。
2、在 条件充许的 情况下，在液流中充气，以局部地或全部地消除低压区。
3、阀门串联使用，以减小每个阀的压降。
4、使阀前后压差低于该介质在调节阀入口温度下产生汽蚀现象的 大允许压差。
5、介质在“流开”状态下工作，允许压差比“流闭”状态大三倍多
结构
自力式压力调节阀因为不需要其它外来能源如电源、气源，仅靠介质自身的能量来驱动，既节能又环保，使用方便，安装完毕后设定好压力值即可投入自动运行，所以在对控制精度要求不高，又缺乏电源、气源的场合，得到了越来越广泛的使用。但在使用过程中，一定要注意选型的特殊性，否则容易引起事故。在使用过程中，要注意使用的选型和安装环境，因此，详细了解自力式压力调节阀的工作原理和结构是非常重要的。
特点
所谓小流量调节阀，顾名思义，就是流通能力很小的调节阀。
阀门的流通能力是在统一条件下的阀门容量指标。我国用c 值表示 。其定义为：阀门全开时，当阀前后压差为1公斤/厘米 2 ，介质重度为1克/ 厘米 3 时 ，每小时流过阀门的介质量(米 3 /时)。对于不可压缩流体，在充分湍流的状态下阀门的流通能力仅仅取决于阀本身的结构。在计算所需的阀门流通能力时，应注意介质不同或流动条件不同时， 阀内流动 状态会有很大的差异。
在小流量情况下，尤其是粘性流体和低压下工作时，流体的主约束往往是层流或层流和湍流的混合态。层流时，经过阀门的介质流量和阀前后压差呈线性关系。而在层流和湍流混合态下，随着雷诺数的增加，即使压差不变，流经阀门的介质量也会增加。在完全湍流时，流量才不随雷诺数变化而变化。尽管如此，选择小流量调节阀，仍然用传统的方法和计算公式进行。但是其计算值和实际值偏离很大，据资料介绍在 cv=0.01以下时，它只是作为一个容量指标，具有参考意义而已。实际流通能力应根据经验确定。
随着流通能力减小，阀门的可调比将下降。但 少也能保证10:l到15:1之间，如果可调比再小，就难以进行流量的调节。
