六、单向阀、液控单向阀、SV/SL型液控单向阀、叠加式液控单向阀
1.结构和工作原理
单向阀又称止回阀或逆止阀。用于液压系统中防止油流反向流动。单向阀有直通式和直角式两种。如图15、图16所示。
SV和SL型液控单向阀都是座式阀，由液压开启，能给出反向流。
这种阀用来隔离局部压力回路，即作为在管子破裂时防止负载降落的保护，也可防止负载下爬。这种液控单向阀主要包括阀体、主阀、先导阀、压缩弹簧和控制活塞 。
SV型阀(无泄油口)一一泄漏油内部回油
由A口至B口始终可以流动。反方向上则导阀和主阀被压缩弹簧和系统压力保持在阀座上。若X口供给压力油则控制活塞被推向右。
这首先打开导阀，然后打开主阀。于是油液先通过导阀，然后通过主
导阀。为了保证用控制活塞能可靠地操纵，需要一定的*低控制压力。
SL型阀(带泄油口)-一-泄漏油外部回油
在原理上，此阀与SV型有相同的功能。不同之处在于增加了泄油口Y,这就可使控制活的环形面积与A口隔离。A口来的油压只作用在控制活塞的面积A4上，从而有效地降低此条件下所需的控制压力。
Z2S型叠加式液控单向阀
Z2S型单向阀是叠加式液控单向阀。它可用于关闭一个或两个工作油口，无泄漏持续时间长，稳定性好。
油液从A到A1或B到B1自由流通，反向则被截止。如果油流通过阀，例
如从A到A1，压力油作用在阀芯上，阀芯则向右运动并推动钢球离开阀座。单向阀被控制油打开时，油可从B1到B流通。压力在B1腔卸荷，单向阀全部开启。为保证两个主单向阀在换向阀中位时能可靠的关闭，阀的A、B口与回油路连接。
2.单向阀的主要故障
单向阀可能出现的*主要的故障，是当油液从P2腔反向进入时，锥阀芯(或钢球)不能将油液严格封闭而产生渗漏。这种渗漏现象更容易出现在反向流油的压力比较低的情况。这时需要检查阀芯锥面(或钢球)与阀座的接触是否紧密;或检查阀座孔与阀芯孔是否保证所需要的同轴度要求，或者当阀座压入阀体孔时有没有压歪。如不符合要求，则需将阀芯锥面(或钢球)与阀座重新配研，或者将阀座拆出重新压装，直到与阀芯锥面(或钢球)严密接触为止。
另外单向阀的阀座或阀套与阀体间的密封装配或拆装时挤伤，而造成内部泄漏。
如果单向阀启闭不灵活，这种阀芯有卡阻现象，则需检查阀体孔与阀芯的加工几何精度，以及二者的配合间隙是否符合要求。这种现象有可能出现于正向开启压力很小的单向阀，或者这种开启压力很小的单向阀是阀芯轴线沿水平方向安装使用时的场合;另外，也应检查弹簧是否断裂或者过分弯曲而引起卡阻。这里应该注意的是，不论是直通型单向阀还是直角型单向阀，都不允许阀芯锥面向上安装。

七、电磁换向阀和电液换向阀
1.结构和工作原理
WE型电磁换向阀采用湿式交流或直流电磁铁。该阀是通过电磁铁控制阀芯的不同工作位置。当电磁铁断电时，阀芯靠弹簧压力保持在中间或终端位置(脉冲式阀除外)。电磁铁通电，阀芯被推到工作位置上，断电后又恢复到初始状态。这时用手推动故障检查按钮可使阀芯移动。
由于湿式电磁铁内部与回油腔相通，这样衔铁油里移动，可以减少磨损、缓冲，并且提高了散热性能，提高了使用寿命。交流电磁铁具有动作时间短，电气控制线路简单，不需特殊的触头保护等特点。直流电磁铁是切换特性软，动作频率高，对过载或低电压反应不敏感，工作可靠。
WE型换向阀是由电磁铁控制的滑阀式换向阀，它主要用于控制液体的通断和流动方向。
其结构主要是由阀体、电磁铁、滑阀以及复位弹簧等组成。在不通电的情况下被复位弹簧保持在中间位置或初始位置上(脉冲阀除外)。电磁铁的推力通过推杆作用在滑阀上，并且把它从静止位置推到工作位置上(终端位置)，由此改变了液流的方向P→A和B→T或者P→B和A→T。当电磁铁断电后，滑阀被复位弹簧重新推到原来的静止位置上。在电磁铁断电时，用故障检查按钮推动滑阀移动。
WEH型换向阀
WEH型换向阀是由电磁阀作为先导控制的滑阀工换向阀。用于控制液流的通断和流动方向。
换向阀是由主阀体、主阀芯、-个或二个复位弹簧和带一个或二个电磁铁的先导阀组成。主阀芯借助于弹簧力或液压力保持中间位置。先导阀可选择湿式直流(或交流)电磁铁，用先导阀的控制油使主阀芯换向(移位)。
当电磁铁不通电时，推动故障检查按钮可导阀芯移动。控制油的输入与输出可选用内控或外控。
弹簧对中的三位四通换向阀( 4WEH25,, 60/,型)
主阀芯是靠两个弹簧保持在中间位置，两弹簧腔与导阀T腔相通(无背压)。控制油从通道引入供给先导阀，当先导阀换向后控制油作用在主阀芯两端中的一端上，推动主阀芯换向，从而使各油口按滑阀机能接通。当电磁铁断电时，导阀芯回到初始位置(脉冲阀除外)，控制油腔
通过导阀T腔与油箱接通，在弹簧力的作用下，主阀芯回到中间位置。弹簧内的控制油经先导阀T腔或外排口Y排出。
压力对中的三位四通换向阀(4WEH25H,,60/,型)
在这种结构中是通过压力油作用在主阀芯的两端面上，由阀体内的定位套使主阀芯保持在中间位置上。
如果主阀芯一端卸荷，则主阀换向，使相应的油口接通;此卸荷端的控制油通过先导阀通过通道Y排出。
二位四通换向阀有4种不同的结构
1.4WEH,, /,型:先导阀和主阀中各有一个复位弹簧(当电磁铁断电时，
使主阀芯固定在初始位置上)
2.4WEH，H/,, /,型:先导阀有一个复位弹簧，由它来控制导阀芯保持在初始位置上。
3.4WEH,, H，/0.,型: 先导阀有两个电磁铁。在先导阀和主阀里都没有复位弹簧，在这种情况下分别由电磁铁和压力油的同时作用下使主阀芯换向。因此就总有一个电磁铁处于工作状态。
4.4WEH, H/,, /0F,型:先导阀有两个电磁铁，可使阀芯停在某个工作位置上(脉冲式阀)。
主阀上没有定位器，是在压力油作用下移到相应的工作位置。
在上述结构中，主阀芯只有在控制油作用下才能正常动作。
型号H.4WEH25,, 60/,, 6A,:在这种结构里控制油是外供外排型的。控制没从外排口X引入，并通过外排Y排出。

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。
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。
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
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
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。

单向节流阀的结构原理。该阀是管式联接的单向节流阀，其节流口采用轴向三角槽式结构。旋转调节螺母，可改变节流口通流面积的大小，以调节流量。正向流动时起节流阀作用；反向流动时起单向阀作用，这时由于有部分油液可在环形缝隙中流动，可以清除节流口上的沉积物。在阀体2左端有刻度槽，调节螺母3上有刻度，用以标志调节流量的大小。
