调速阀是进行了压力补偿的节流阀。它由定差减压阀和节流阀串联而成。
节流阀前、后的压力p2和p3分别引到减压阀阀芯右、左两端，当负载压力p3增大，于是作用在减压阀芯左端的液压力增
大，阀芯右移，减压口加大，压降减小，使p2也增大，从而使节流阀的压差（p2-p3）保持不变；反之亦然。这样就使
调速阀的流量恒定不变（不受负载影响）
减压阀芯或节流阀芯在全闭位置时，径向卡住会使出油腔没有流量，在全开位置（或节流口调整好）时，
径向卡住会使调整节流调节部分出油腔流量不发生变化。
另外，当节流调节部分发生故障时，会使调节螺杆不能轴向移动，使出油腔流量也不发生变化。发生阀芯
卡住或节流调节部分故障时，应进行清洗和修复。
