力士乐插装阀盖板LFA25H2-7X/F

产品简介：

插装阀与我们所说的普通液压控制阀有所不同，它的通流量可达到1000L/min,通径可达200~250mm。阀芯结构简单，动作灵敏，密封性好。它的功能比较单一，主要实现液路的通或断，与普通液压控制阀组合使用时，才能实现对系统油液方向、压力和流量的控制。

简介

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 。

插装阀原理

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。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。

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可进行测试;集成块在发给用户之前可进行整体测试。

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、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)

功能全、应用广泛

插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。

插装阀的应用

三通阀 由两个方向阀组件并联而成，对外形成一个压力油口、一个工作油口和一个回油口。三通插装阀的工作状态数取决于先导换向阀的工作位置数。

四通阀由两个三通阀并联而成

先导阀可以是一个三位四通换向阀，见动画。

先导阀也可以是两个二位四通换向阀或四个二位三通换向阀，见动画。

四通插装阀的工作状态数取决于先导换向阀的工作位置数。
