插装阀的工作原理及特点
插装阀是另一类液压控制阀的统称。其基本核心元件是一种液控型、单控制口的装于油路主级中的两通液阻单元(故又称二通插装阀)。将一一个或若干个插入元件进行不同的组合，并配以相应的先导控制级，可以组成插装阀的控制功能单元。比如方向控制功能单元、压力控制单元、流量控制单元、复合控制功能单元。
插装阀具有以下特点:内阻小，适宜大流量工作，阀口多数采用锥面密封，因而泄漏小，对于乳化液等地粘度的工作介质也适宜，结构简单、工作可靠、标准化程度高;对于大流量、高压力、复杂的液压系统可以显著的减小尺寸和重量。
其结构:先导阀，控制盖板，插装件。
它是由插入元件、控制盖板、通道块部分组成。插入元件有阀芯、阀套、弹簧和密封件组成;控制盖板上根据插装阀的不同控制功能，安装有相应的先导控制级元件;通道块既是嵌入插入元件及安装控制盖板的基础阀体，又是主油路和控制油路的连通体。其中A、B为主油路通口，C为控制油路通口。A、B、C油口的压力和作用面积分别为PA、PB、PC和A1、A2、A3，A3=A1+A2， Fs为弹簧作用力。
使用二通插装阀的粉末制品液压机液压系统分析
控制上液压缸的液压阀采用了二通插装阀，
控制下液压缸的液压阀采用了滑阀。粉末制品液压机与普通液压机有所不同，下缸装有控制活塞高位置的限程机构，调节限程机构，可控制模具中的装料量。下缸带有中心缸，以满足不同制品的工艺要求。
由于主机各液压缸的大小和速度相差大，所需流量也有大差别，液压系统采用压力补偿轴向柱塞变量泵，可以根据负载的大小，自动变换泵输出的流量,以适应不同工作状态压力和流量的不同要求。液压控制阀采用了二通插装阀与滑阀混合使用，以发挥两种控制阀各自的优点。在液压系统中，上缸液压系统需要大流量,使用了二通插装阀，下缸液压系统需要小流量,使用滑阀，以降。
使用二通插装阀的YA79液压机液压系统分析
液压机液压系统因其压力高，流量大，液压控制阀适于采用二通插装阀,YA液压机液压系统原理，液压系统的液压控制阀全部采用二通插装阀。系统采用双泵供油，泵1为低压大流量泵,用于上缸和下缸的快速行程;泵2为高压小流量泵，用于系统实现压制及保压。液压系统控制部分包括七个集成块。泵1的调压、安全、卸荷及防止油液倒流由集成块②控制，泵2的调压、安全、卸荷由集成块①控制;上缸运动由集成块⑤和⑥控制;下缸运:动由集成块③和④控制;送料缸由集成块⑦控制。
由于液压系统控制阀除送料缸液压系统外，其余部分采用了二通插装阀;集成块,使液压系统结构紧凑、简单,便于安装、调试和维护。系统的工作性能得以改善:速度快、稳定性好、响应快、精度高,系统配以计算机控制,可方便地实现自动控制。
螺纹插装阀的安装方式是采用螺纹直接旋入阀块的插孔里，所以又叫旋入式插装阀，它的小通径为3mm，大通径为32mm，常用通径为4mm、8mm、10mm、12mm、16mm、20mm，高压力可达63MPa，大流量达760L／min，适合于中高压中小流量的液压系统。

换向阀主要由阀体、密封组件、凸轮、阀杆、手柄和阀盖等零部件组成(图1)。阀门由手柄驱动，通过手柄带动阀杆与凸轮旋转，凸轮具有定位驱动与锁定密封组件的开启与关闭功能。手柄逆时针旋转，两组密封组件分别在凸轮的作用下关闭下端的两个通道，上端的两个通道分别与管道装置的进口相通。反之，上端的两个通道关闭，下端两个通道与管道装置的进口相通，实现了不停车换向。
