调节阀用于调节介质的流量、压力和液位。根据调节部位信号,自动控制阀门的开度,从而达到介质流量、压力和液位的调节。调节阀分电动调节阀、气动调节阀和液动调节阀等。本手册主要介绍电动调节阀和气动调节阀两种。
调节阀由电动执行机构或气动执行机构和调节阀两部分组成。调节并通常分为直通单座式和直通双座式两种,后者具有流通能力大、不平衡办小和操作稳定的特点,所以通常特别适用于大流量、高压降和泄漏少的场合。
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。三种注量特性的意义如下:
