H-4WEH25C6X/6HG24N9TK4电液换向阀

电液换向阀是由电磁换向阀作先导阀与液动换向阀组合而成，由电磁阀引进油液，推动主滑阀运动，使主油路换向。主要用于改变油流方向，改变油马达旋转方向，和油缸的运动方向等。也可用以完成卸荷和顺序动作等用途。适用于大流量的液压系统。液动阀换向的快慢可用其控制油路中的单向节流阀来调节。

 

电液动滑阀既能实现换向的缓冲，避免液压系统的换向冲击，同时又能用较小的电磁铁控制较大的液流，所以常在流量较大的系统中应用。

 

电液换向阀有二位与三位，均是四通。按其电磁阀的电源电压可分为交流(110V/220V/380V)、直流(24V/110V/220V)两种。

 

P为进油口，O为回油口，AB至油缸两端。K为电磁先导阀的进油口，L为电磁先导阀的回油口，L应该直通回油池，不应通过任何的背压阀，亦避免与回油O连通。

 

主要结构品种：

1．电液换向的先导电磁阀为NG6、NG10二种。

2．电液换向阀的控制电磁铁有干式型、湿式型二种结构，工作电源有交流、直流二种。

3．电液换向阀有二位四通无弹簧型、三位四通弹簧对中型及行程调节型三种，后者可

借助调节螺钉改变阀芯的移动距离，以调整进出阀的流量，起到节流调速的作用。

4．在电磁导阀与液动阀的控制之间，可加入阻尼调节阀，以控制主阀芯的换向速度。

方向控制阀

方向控制阀用于控制或调节液压系统或回路中方向及其通和断,从而控制执行元件的

运动方向及其启动、停止的阀。如单向阀、换向阀等;

大型钢厂现场采用的主要方向控制阀，如:电磁换向阀、手动换向阀、电液换向阀、单向阀、方向插件，插装阀。

3、4WEH..型方向阀

型号4WEH..型方向阀WEH型方向阀是-种电液操作的方向滑阀。它们用于控制液流的开启、停止和方向。

此类阀组成主要包括阀体( 1 )主控制阀芯(2 )一个或两个复位弹簧( 3.1 )和(3.2 ),带一个或两个电磁铁:电磁铁"a” (5.1 ),电磁铁"b" (5.2 )的先导阀(4)。

主阀阀芯由弹簧或液压力保持在中位或初始位置。在初始位置, 两个弹簧腔( 6 )和( 8 )通过先导阀无压的油箱连通。经过控制油路(7 )向先导阀(4)供油。控制泊可以由内部或外部供给( 外部供给油口X )当先导阀操作时,如电磁铁"a”得电,先导滑阀(10)向左移动,因此弹簧腔(8)获得先导油压力而弹簧腔(6)保持无压状态。

先导压力施压于主阀芯的左端, 并克服弹簧力( 3.1),其结果,主阀的P至B和A至T被接通。当电磁铁断电,先导阀回复至初始位置(带定位机构滑阀除外),弹簧腔( 8 )向油箱卸荷。

控制油从弹簧腔经先导阀排入Y口。控制油可内部或外部供油和回油外部经油口Y )可选择的应急手动操作( 9 ),在电磁铁不通电情况下,可对先导滑阀( 10 )进行操作。

电液阀是由一个主阀和两个电磁阀组成，主阀响应速度的控制是两个柱塞阀，安装于主阀的入口和出口。通过两个柱塞阀细微调节主阀的启闭速度。调整这些装置（柱塞阀）以控制流入和流出活塞上方介质的流量。达到主阀启闭速度能基于介质的粘度及压力调整的目的。

换向阀有两组密封组件。每组密封组件(图2)由阀瓣、密封圈、调整块、调节螺钉、夹板和螺栓组成。阀瓣为碳钢板焊件，设有加强筋，即增加阀瓣强度又起导向作用，保证每组阀瓣间的同轴度。阀瓣上镶嵌聚氨脂橡胶圈，该材料具有耐油、耐磨损、性能稳定、密封良好和使用寿命长的特点。在凸轮的作用下，密封圈的球面与阀体密封面相接触产生挤压弹性变形，达到密封效果。调整块和调节螺钉在两组密封组件不能同步到位时可起调整作用，确保各通道密封性能同步到位。

电液比例阀是比例控制系统中的主要功率放大元件,按输入电信号指令连续地成比例地控制液压系统的压办流量等参数。与伺 服控制系统中的伺服阀相比,在某些方面还有一-定的性能差距(主要性能比较如表1所示),但它显著的优点是抗污染能力强,大大地减少了由污染而造成的工作故障,提高了液压系统的工作稳定性和可靠性。另一方面比例阀的成本比伺服阀低，结构也简单,已在许多场合获得广泛应用。
