通过启闭件（阀瓣）的运动，改变通路截面积， 用以调节流量、压力的阀门称为节流阀。
节流阀在外形和结构上都与截止阀非常相似，所不同的只是阀瓣的形状和工作行程，因此，节流阀与截止阀的零部件通用程度很高。
各种截断阀都可以改变介质通道截面积，因而在一定程度上也可以起到调节作用，但是它们的调节性能不好。这是因为它们的启闭件和阀杆是活动连接的，在连接处有间隙，不便调节；启闭件的升降与通道面积的改变不成比例，因而不易做到准确、连续调 节；当通道面积小而介质流速很大时，会造成密封面的严重冲蚀，并引起阀瓣的振动。因而通常都采用专门结构和启闭件形状的节流阀进行调节。
图11-1所示的Z形流道式节流阀，其内部结构简单，属于粗调式节流阀，行程的大小与流量变化关系无法事先标定，只能借助另外的流量测试仪表临时加以判断，所以，这种阀只用于一般工艺管路。
图11-2所示的角式节流阀，其结构复杂，属于细调式节流阀，它有三个特点：①采用针形阀瓣，工作行程大，行程与流量变化的关系具有较小的斜率； ②采用螺旋测微机构标定行程，精度高而且稳定，为事先标定行程与流量变化关系曲线提供了有利的条 件；③结构紧凑，轻巧，密封性能好，安装位置与形式不受限制。因此，它可用于调节精度要求较高的工艺分析管路和小流量精密调节工位，既能方便地安装于仪表控制盘上，又能直接安装于各种管路中，当安装于仪表控制盘上时，可将锁紧螺母旋下，待阀门插入控制盘孔后再复位并拧紧即可。
11.3.1节流阀的阀瓣
节流阀阀瓣主要有以下几种形状。压力继电器HED80H20/100K14
