伺服控制阀

伺服控制阀输入信号(电量、机械量)多为偏差信号(输入信号与反馈信号的差值),阀的输出量(压力、流量)也按照其输入量连续、成比例地进行控制的阀。这类阀的工作性能类似于比例控制阀,但具有较高的动态瞬应和静态性能,多用于要求较高的、响应快的闭环液压控制系统。

大型钢厂现场采用的主要伺服阀如:伺服阀，

1、基本结构：

主阀体（阀芯/阀套）、先导阀（伺服射流管）、电气控制盒（放大版）

2、工作原理

伺服射流管先导级

射流管先导级主要由力矩马达、射流管和接收器组成。

当线圈中有电流通过时,产生的电磁力使射流管喷嘴偏离零位,管内的大部分液流集中射向一侧的接收器,而另一侧接收 器所得到的流量减少,由此造成两接收器的压力变化。主阀阀芯因此压差而产生位移。

先导级的泄漏油通过喷嘴环形区域处的排出通道直接回油箱。

多级阀的工作原理

多级阀中的功率级阀芯的位置闭环控制是由阀内控制电路来实现的。对控制电路中的位移控制器输入一个指令信号(与阀期望输出的流量成正比),同时位移传感器通过一激励器测出功率级阀芯的实际位移(以与实际位移成正比的电压形式出现),次位移信号被调解并反馈至位移控制器与指令信号相比较,得出的偏移信号驱动先导级并使功率级阀芯

产生位移,直至偏差信号为零。

由此得到功率级滑阀的位移与指令电信号成正比。

比例阀VT-NE30-2X的输入压力为零.即.;时,输出腔的压力通过比例阀皮圈凸筋间空酸从唇口泄去高压,同时,当比例阀芯所受的弹簧力大于向右的液压力时,比例阀弹簧将比例阀芯推回原始位置,使比例阀芯与比例阀皮圈内孔完全分离而完全泄压.此时输入输出压力为零.随着输入压力.加大,即左加大,使比例滑阀单向力平衡遭破坏.当<>&;6-时,比例阀芯左移与比例阀皮圈产生间隙形成节流并混合比倒阀常见的故障为:1,输入输出压力同步.2,低压时辅人输出压力同步,高压时输入输出压力正常.3,低压时输入输出压力正常,高压时输入输出压力不正常.
