插装阀基本组件

组件由阀芯、阀套、弹簧和密封圈组成。根据用途不同分为方向阀组件、压力阀组件和流量阀组件。同一通径的三种组件安装尺寸相同，但阀芯的结构形式和阀套座直径不同。三种组件均有两个主油口A 和B、一个控制口x 。

插装阀在流体控制功能的领域的使用种类比广泛，已应用的元件有是电磁换向阀，单向阀，溢流阀，减压阀，流量控制阀和顺序阀。通用性在流体动力回路设计和机械实用性的延伸，充分展示了插装阀对系统设计者和应用者的重要性。由于其装配过程的通用性、阀孔规格的通用性、互换性的特点，使用插装阀完全可以实现完善的设计配置，也使插装阀广泛地应用于各种液压机械。

以轮式装载机为例，采用插装阀集成块来代替故障不断、难以诊断和维修的动力传动控制装置。原有控制系统有60多个连接管件和19个元件。用来替代的整体特制集成块上只有11个管件和17个元件。体积为12 x 4 x 5立方英寸，是原系统所占空间的20%。采用插装阀的特点如下：

减少安装时间 减少泄漏点 减少易污染源 减少维修时间（因为插装阀无需取下管接头配件即可更换）

插装阀单元的工作状态 记油口A、B、x的压力分别为pA、pB、px， 作用面积分别为AA、AB、Ax， 阀芯上端复位弹簧力为Ft ， 当 pxAx Ft >pAAA pBAB 时 阀口关闭 ； 当 pxAx Ft ≤ pAAA pBAB 时 阀口开启。

实际工作时，阀芯的受力状况是通过油口x的通油方式控制的。

泄压功能

用于泄压功能的插装阀 (1)（类型 LC . DB...）设计为无面积差的座阀（B 口无有效面积）。油口 A 的有效压力通过先导供油孔 (5) 引导至元件的弹簧侧 (6)。在先导控制阀 (4) 设置的压力下，阀芯 (3) 进行压力补偿并由弹簧力关闭。

达到设定压力后，阀芯 (3) 打开，端口 A 的压力根据压力-流量特性进行限制。

减压功能

休息位置关闭

对于具有开启特性的减压功能，应用了限压插装阀（LC..DB40D...型）和带减压先导控制阀（LFA..DR...型）的控制盖。先导油通过供油孔和打开的先导控制阀从端口 A 导向 B 侧。

主阀芯打开，从 A 口到 B 口的流量被释放。

达到设定压力后，阀芯关闭，端口 B 的压力根据压力-流量特性降低。二次侧增加的电位压力通过先导控制阀的第三路排放到油箱。方向阀的设置可以实现附加的闭锁功能（LFA..DRW...型）。

压力排序功能

此功能可实现第二个系统的压力相关连接。

所需的切换压力在集成在控制盖中的先导控制阀上设置。

先导供油可以通过外部（先导油口 X）或内部（从 A 口经先导油口 X 或 Z2）实现。

先导控制弹簧室通过油口 Y 或 Z1 被引导，减压到油箱。

电路示例

示例 1：（低压系统的压力相关卸载电路）

在图示的回路中，系统通过高压泵和低压泵供气。系统压力p S从高压侧通过先导控制阀上的先导油口X对外作用，达到设定压力值后将低压侧设置为减压循环。止回阀 RV（不包括在供货范围内）阻止高压系统与现已减压的低压系统连接。

在达到先导控制弹簧上设定的压力时，先导控制阀被切换，主阀到油箱的弹簧腔被卸载。主阀芯打开，A 到 B 的连接被释放。

对于 LFA..DZW... 型，除了液压回路外，还可以通过电动先导控制阀选择所需的开关位置（不包括在控制盖 LFA..DZ... 的交付范围内） ）。
