比例控制阀

采用比例电磁铁(或力矩马达)将输入信号转换成力或阀的机械位移，使阀的输出(压力、流量)也按照其输入量连续、成比例地进行控制的阀。

比例阀三种形态

（1）电磁式 电磁式是指采用比例电磁铁作为电气一机械转换元件的比例阀，比例电磁铁将输入的电流信号转换成力、位移机械信号输出．进而控制压力、流量及方向等参数。

（2）电动式 电动式是指采用直流伺服电动机作为电气一机械转换元件的比例阀，直流伺服电动机将输入的电信号．转换成旋转运动转速，再经丝杆螺母、齿轮齿条或齿轮凸轮等减速装置和变换机构，输出力与位移，进一步控制液压参数。

（3）电液式 电液式是指采用力矩马达和喷嘴挡板的结构为先导控制级的比例阀。对力矩马达输入不同的电信号，并通过同它连接在一起的挡板（有时力矩马达的衔铁就是挡板）输出位移或角位移，改变挡板和喷嘴之间的距离，使喷嘴喷出的油液流阻产生变化，进而控制输小参数。

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。

此型号的阀门是电动操作式二级伺服方向阀，其油口安装面符合 ISO 4401-03-02-0-05 标准。 它们主要用于控制位置、力、压力或速率。

这些阀门由机电转换器（力矩马达）(1)、液压放大器（原理：喷嘴挡板）(2) 和套筒（第二级）中的控制阀芯 (3)（通过机械反馈连接到力矩马达）组成。

力矩马达线圈 (4) 上的电气输入信号通过较好磁体产生作用于电枢 (5) 的力，并与弹性管 (6) 一起产生扭矩。这导致通过螺栓连接到弹性管 (6) 的挡板 (7) 从两个控制喷嘴 (8) 之间的中心位置移开，并且在控制阀芯 (3) 的前侧产生压差。压差导致阀芯改变位置，并导致压力油口连接一个执行机构油口，同时，另一个执行机构油口连接到回流油口。

控制阀芯通过弯曲弹簧（机械反馈）(9) 连接到挡板或力矩马达。阀芯的位置将改变，直到弯曲弹簧的反馈扭矩和力矩马达的电磁扭矩达到平衡并且喷嘴挡板系统的压差变为零。

因此，控制阀芯的行程和伺服阀的流量是与电气输入信号成比例来控制的。必须注意的是，流量取决于阀压降。

用于外部控制电子元件的型号 4WS2EM 6-2X/…

外部控制电子元件（伺服放大器）操作阀门并放大模拟输入信号（控制值），以便通过输出信号以流量控制形式驱动伺服阀。

带有 OBE 的型号 4WSE2EM 6-2X/…

要放大模拟输入信号，需集成特别针对此阀类型进行过调整的控制电子元件 (10)。它们与位于力矩马达盖帽中的连接器 (11) 相连接。

安全阀是启闭件受外力作用下处于常闭状态，当设备或管道内的介质压力升高超过规定值时，通过向系统外排放介质来防止管道或设备内介质压力超过规定数值的特殊阀门。安全阀属于自动阀类，主要用于锅炉、压力容器和管道上，控制压力不超过规定值，对人身安全和设备运行起重要保护作用。注安全阀必须经过压力试验才能使用。
