产品描述
调速阀是由定差减压阀与节流阀串联而成的组合阀。节流阀用来调节通过的流量，定差减压阀则自动补偿负载变化
的影响，使节流阀前后的压差为定值，消除了负载变化对流量的影响。
节流阀前、后的压力分别引到减压阀阀芯右、左两端，当负载压力增大，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，从而使节流阀的压差保持不变；反之亦然。这样就是调速阀的流量恒定不变
（不受负载影响）。调速阀也可以设计成先节流后减压的结构。
一般调速阀不带温度补偿， 可用在机床、动力头滑台及类似设备上 ；另一种带温度补偿装置，把转动式的阀芯改
成薄刃结构的滑阀式阀芯以减少温度对流量的影响。因为节流阀的节流缝隙越短 ，温度对流量的影响就越小， 这是
一种受温度影响较小的流量控制阀。或者是在调节螺钉与阀芯之间加一根用热敏性较大材料制成的感温杆， 温度变
化时，利用阀芯的热胀冷缩来自动调节阀芯和阀体间形成的节流面积。带温度补偿的调速阀通常用在对调速性能要
求很高的设备上。
调速阀的常见故障及排除
（一） 流量调节失灵
这是指调整节流调节部分，出油腔流量不发生变化，其主要原因是阀芯
径向卡住和节流调节部分发生故障等。主要原因是锁紧装置松动，节流口部分堵塞，油温升高，进、出油腔*小压差
过低和进、出油腔接反等。因此在使用时要注意进、出油腔的位置，避免接反。
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。
