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 。

HAWE插装阀工作原理//哈威插装阀原理

　　1.HAWE插装阀设计因素

　　插装阀和其阀孔的设计通用性的重要性在于大批量生产。就某一种规格的插装阀为例，为了批量生产，其阀口的尺寸是统一的。此外，不同功能的阀可采用同一规格阀腔，例如：单向阀、锥阀、流量调节阀、节流阀、两位电磁阀等等。如果同一规格、不同功能的阀无法采用不同阀体，那么阀块的加工成本势必增加，插装阀的优势就不复存在。插装阀在流体控制功能的领域的使用种类比较广泛，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。

　　2.HAWE插装阀体积小、成本低

　　批量生产的对用户益处在阀块还未装配线终点时就已显现。采用插装阀设计的整套控制系统可为用户大大减少制造工时;该控制系统的每个元件在组装成集成阀块前就可进行独立测试;集成块在发给用户之前就可进行整体测试。由于必须安装的元件和连接的管路大大减少，为用户节省大量的制造工时。由于系统污染物的减少，泄漏点的减少和装配错误的降低，使可靠性显著提高。插装阀的应用实现了系统的高效、方便。　　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个独立元件。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12x4x5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)

　　3.HAWE插装阀功能全、应用广泛

　　装阀已经广泛应用于多种工程机械、物料搬运机械和农业机械。在常被忽视的工业领域中，插装阀的应用在不断的扩大。特别是在许多重量和空间的限制的场合中，传统工业液压阀束手无策，而插装阀却大显身手。在某些应用场合，插装阀是提高生产力和竞争力的唯一选择新型插装阀的功能正不断被开发出来。这些新开发成果将保证将来可持续的生产效益。过去的经验证明：想象力的贫乏是采用插装阀实现生产既期效益的唯一限制。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。X通回油箱，阀口开启;x与进油口相通，阀口关闭。改变油口通油方式的阀称为先导阀。

哈威插装阀的工作原理：
①当控制油路未接通压力油液时，液控单向阀就象普通单向阀一样工作，压力油只从进油口流向出油口，不能反向流动。
②当控制油路有控制压力输入时，活塞顶杆在压力油作用下向右移动，用顶杆顶开单向阀，使进出油口接通。若出油口大于进油口就能使油液反向流动。
