流量控制阀功用 功能:通过改变阀门的过流面积来控制输出流量??执行元件的运动速度 流量控制阀分类：节流阀、调速阀、分流阀、温度补偿调速阀 节流阀组成：阀体、阀芯、弹簧、调节手轮等 工作原理：调节手轮，阀芯移动， A变化，q变化。
特点：∵进口压力油通过弹簧腔径?向小孔和阀体上的斜孔同时作用在阀芯的上下两端 ∴即使在高压下，调节阀口比较方便 调速阀 ∵q=CA△pφ F变化，△p变化， A=C，q仍变化 ∴v稳定性要求较高时，用调速阀??调速阀的组成 组成部分差减压阀与节流阀串联 减压阀阀芯受力平衡方程 ∵p2A=p3A+Ft ∴p2-p3=Ft/A=kX0/A ∵k较小且不可调，工作时阀芯移动很小。
∴Ft≈c△p=p2-p3=Ft/A≈c 故??当A=c时，q=c，v=c 调速阀的工作原理 F↑,p3↑，减压阀阀芯右移，x↑，减压作用↓，p2↑，使△p=p2-p3，基本不变 反之：F↓，p3↓减压阀阀心左移，x↓，减?压作用↑，p2↓仍使△p=p2-p3基本不变 ∴F皆有△p=c，若A=c，则q=c 调速阀的流量特性 ∵对调速阀，当△p最大，不减压， 最小压差△pmin>△p——相当于节流阀，中低压，=0.5MPa 最小压差△pmin1Mpa ∵调速阀虽然解决了负载变化对流量的影响，但温度变化?对流量仍有影响。
温度补偿调速阀的组成：在上述调速阀中节流阀的推杆部分加上一根温度补偿杆（一般用聚氯已烯塑料），且将阀口变成薄刃形（轴向缝隙式） 温度补偿调速阀的工作原理：利用温度补偿杆的热胀冷缩补偿流量 k↑q↑ T↑<>从而使q稳定 L↑A↓q↓ 90L075-KA-5-AB-80-S-3-C6-D-03-GBA-20-20-20 90L075KA5AB80S3C6D03GBA202020
