伺服阀是-种根据输入信号及输出信号反馈量连续成比例地控制流量和压力的液压控制阀。根据输入信号的方式不同，又分电液伺服阀和机液伺服阀。电液伺服阀将小功率的电信号转换为大功率的液压能输出，实现执行元件的位移、速度、加速度及力的控制。
电液伺服阀由电气一机械转换装置、液压放大器和反馈(平衡)机构三部分组成。
电气一机械转换装置将输入的电信号转换为转角或直线位移输出，常称为力矩马达或力马达。
电液比例阀是一种性能介于普通控制阀和电液伺服阀之间的新阀种。它既可以根据输入电信号的大小连续成比例地对油液的压力、流量、方向实现远距离控制、计算机控制，又在制造成本、抗污染等方面优于电液伺服阀。
电液比例阀根据用途分为:电液比例压力阀，电液比例流量阀，电液比例方向阀。
电液比例阀的控制性能低于电液伺服阀，因此广泛应用于要求不高的一般工业部门。

电液比例多路阀负载传感与压力补偿技术
节约能量、降低油温和提高控制精度，同时也使同步动作几个执行元件运动时互不干扰，现较先进工程机械都采用了负载传感与压力补偿技术。负载传感与压力补偿是一一个很相似概念,都是利用负载变化引起压力变化去调节泵或阀压力与流量以适应系统工作需求。负载传感对定量泵系统来讲是将负载压力负载感应油路引至远程调压溢流阀上，当负载较小时，溢流阀调定压力也较小;负载较大，调定压力也较大，但也始终存一定溢流损失。变量泵系统是将负载传感油路引入到泵变量机构，使泵输出压力随负载压力升高而升高(始终为较小固定压差)，使泵输出流量与系统实际需要流量相等，无溢流损失，实现了节能。压力补偿是提高阀控制性能而采取一种保证措施。将阀口后负载压力引入压力补偿阀，压力补偿阀对阀口前压力进行调整使阀口前后压差为常值，这样节流口流量调节特性流经阀口流量大小就只与该阀口开度有关，而不受负载压力影响。

工程机械电液比例阀先导控制与遥控
电液比例阀和其它专用器件技术进步使工程车辆挡位、转向、制动和工作装置等各种系统电气控制成为现实。一般需要位移输出机构可采用比例伺服控制手动多路阀驱动器完成。电气操作具有响应快、布线灵活、可实现集成控制和与计算机接口容易等优点,现代工程机械液压阀已越来越多采用电控先导控制电液比例阀(或电液开关阀)代替手动直接操作或液压先导控制多路阀。采用电液比例阀(或电液开关阀)另一个显著优点是工程车辆上可以大大减少操作手柄个数，这使驾驶室布置简洁，能够有效降低操作复杂性，对提高作业质量和效率都具有重要实际意义。

电液比例阀工程机械上应用实例
汽车起重机液压系统。该机采用了3片型比例多路阀，负载传感油路中3个梭阀将3个工作负载中大压力选出来送至远程调压溢流阀远控口，调整溢流阀溢流压力，使液压泵输出压力恰好符合系统负载需要即可，达到一定节能目。压力补偿油路使每一片阀流量仅与该阀开度有关，而所承受负载无关，它阀片所承受负载也没有关系，达到任一负载下均可随意控制负载速度目。
推土机推土铲手动与电液比例先导控制实例。当二位三通电磁阀不通电时，先导压力与手动减压式先导阀相通，梭阀选择来自手动先导阀压力对液动换向阀进行控制;当二位三通电磁阀通电时，先导控制压力油通向三通比例减压式先导阀，梭阀对液动换向阀进行控制。

比例控制技术是在开关控制技术和伺服控制技术之间的过渡技术，采用比例放大器控制比例电磁铁，实现对比例阀的连续控制，从而实现对液压系统压力、流量、方向的无级调节；但是用比例方向阀进行速度控制时，如果负载是变化的，那么执行元件的速度就会受负载变化的影响（负载小时速度快，负载大时速度慢）；于是在系统设计时，人们引入了压力补偿器，它可以使比例阀阀口的压差保持恒定，使执行元件的速度不受负载变化的影响。

某钢厂步进梁式加热炉中步进梁升降液压回路。 此回路使用了比例方向阀与进口压力补偿。 由于步进梁下降时，存在超越负载，所以在油缸无杆腔设置了平衡阀。 压力补偿器的弹簧调定后（这里为定值）,比例阀节流口的压差 Δp 就近似为恒定值,即比例方向阀进油口前后压差 Δp 保持恒定值。 当节流口前后压差保持不变时,通过节流口的流量只与节流口的开口面积成正比。 对比例方向阀而言, 进油节流口的开口面积与比例方向阀的输入电流信号有关,而与负载的变化无关。 亦即升降油缸的供油流量 Q 只与比例方向阀的输入电流信号有关,与负载的变化无关。

液压系统的组成及其作用
一个完整的液压系统由五个部分组成，即动力元件、执行元件、控制元件、辅助元件(附件)和液压油。
动力元件的作用是将原动机的机械能转换成液体的压力能，指液压系统中的油泵，它向整个液压系统提供动力。液压泵的结构形式一般有齿轮泵、叶片泵和柱塞泵。
执行元件(如液压缸和液压马达)的作用是将液体的压力能转换为机械能，驱动负载作直线往复运动或回转运动。
控制元件(即各种液压阀)在液压系统中控制和调节液体的压力、流量和方向。根据控制功能的不同，液压阀可分为村力控制阀、流量控制阀和方向控制阀。压力控制阀又分为益流阀(安全阀)、诚压阀、顺序阀、压力继电器等;流量控制阀包括节流阀、调整阀、分流集流阀等，方向控制阀包括单向阀、液控单向阀、梭阀、换向阀等。根据控制方式不同，液压阀可分为开关式控制阀、定值控制阀和比例控制阀。
辅助元件包括油箱、滤油器、油管及管接头、密封圈、快换接头、高压球阀、胶管总成、测压接头、压力表、油位油温计等。
液压油是液压系统中传递能量的工作介质，有各种矿物油、乳化液和合成型液压油等几大类。

液压系统结构
液压系统由信号控制和液压动力两部分组成，信号控制部分用于驱动液压动力部分中的控制阀动作。
液压动力部分采用回路图方式表示，以表明不同功能元件之间的相互关系。液压源含有液压泵、电动机和液压辅助元件;液压控制部分含有各种控制阀，其用于控制工作油液的流量、压力和方向;执行部分含有液压缸或液压马达，其可按实际要求来选择。
在分析和设计实际任务时，一般采用方框图显示设备中实际运行状况。空心箭头表示信号流，而实心箭头则表示能量流。
基本液压回路中的动作顺序一控制元件(二位四通换向阀)的换向和弹簧复位、执行元件(双作用液压缸)的伸出和回缩以及溢流阀的开启和关闭。对 于执行元件和控制元件，演示文稿都是基于相应回路图符号，这也为介绍回路图符号作了准备。
根据系统工作原理，您可对所有回路依次进行编号。如果一个执行元件编号为0，则与其相关的控制元件标识符则为1。如果与执行元件伸出相对应的元件标识符为偶数，则与执行元件回缩相对应的元件标识符则为奇数。不仅应对液压回路进行编号，也应对实际设备进行编号，以便发现系统故障。
DIN ISO1219-2 标准定义了元件的编号组成，其包括下面四个部分，设备编号、回路编号、元件标识符和元件编号。如果整个系统仅有一种设备，则可省略设备编号。
实际中，另一种编号方式就是对液压系统中所有元件进行连续编号，此时，元件编号应该与元件列表中编号相一致。这种方法特别适用于复杂液压控制系统，每个控制回路都与其系统编号相对应。

液压或气动技术在工业中的应用
液压传动和气压传动统称为流体传动，是根据17世纪帕斯卡提出的液体静压力传动原理，利用液体与气体来传递能量的一门新兴技术，是工农业生产中广为应用的一门技术。液压技术*初用水作为工作介质，以水压机的形式将其应用于工业上，后来随着技术的逐步进步，介质改为油，至今大部分的液压机械仍然是使用油作为介质，但制造出来的产品无论在性能、范围、用途等各方面都是以往的技术所不能比及的。经过二百多年的发展，到如今，流体与气体传动技术水平的高低已成为一个国家工业发展水平的重要标志。液压与气动技术开始大范围的应用是在二十世纪，特别是1920年以后，发展更为迅速。液压元件大约在19世纪术20世纪初的20年间，才开始进入正规的工业生产阶段。1925年维克斯发明了压力平衡式叶片泵，为近代液压元件工业或液压传动标准的逐步建立奠定了基础。20世纪初康斯坦丁尼斯克对能量波动传递进行了理论及实际研究。
液压技术一般应用于重型、大型、特大型设备，如冶金行业轧机压下系统，连铸机压下系统等;高速响应随动系统等工程机械，抗冲击，要求功重比较高系统一般都采用液压系统，这是应用液压技术的三个领域。

液压传动基本原理
从原理上来说，液压传动所基于的基本的原理就是帕斯卡原理，就是说，液体各处的压强是一致的，这样，在平衡的系统中，比较小的活塞上面施加的压力比较小，而大的活塞上施加的压力也比较大，这样能够保持液体的静止。所以通过液体的传递，可以得到不同端上的不同的压力，这样就可以达到一个变换的目的。我们所常见到的液压千斤顶就是利用了这个原理来达到力的传递。液压传动中所需要的元件主要有动力元件、执行元件、控制元件、辅助元件等。其中液压动力元件是为液压系统产生动力的部件，主要包括各种液压泵。液压泵依靠容积变化原理来工作，所以一般也称为容积液压泵。齿轮泵是常见的一-种液压泵，它通过两个啮合的齿轮的转动使得液体进行运动。其他的液压泵还有叶片泵、柱塞泵，在选择液压泵的时候主要需要注意的问题包括消耗的能量、效率、降低噪音。液压执行元件是用来执行将液压泵提供的液压能转变成机械能的装置，主要包括液压缸和液压马达。液压马达是与液压泵做相反的工作的装置，也就是把液压的能量转换称为机械能，从而对外做功。液压控制元件用来控制液体流动的方向、压力的高低以及对流量的大小进行预期的控制，以满足特定的工作要求。正是因为液压控制元器件的灵活性,使得液压控制系统能够完成不同的活动。液压控制元件按照用途可以分成压力控制阀、流量控制阀、方向控制阀。按照操作方式可以分成人力操纵阀、机械操纵法、电动操纵阀等。除了上述的元件以外，液压控制系统还需要液压辅助元件。这些元件包括管路和管接头、油箱、过滤器.蓄能器和密封装置。通过以上的各个器件，我们就能够建设出一个液压回路。所谓液压回路就是通过各种液压器件构成的相应的控制回路。根据不同的控制目标，我们能够设计不同的回路，比如压力控制回路、速度控制回路、多缸工作控制回路等。根据液压传动的结构及其特点，在液压系统的设计中，首先要进行系统分析，然后拟定系统的原理图，其中这个原理图是用液压机械符号来表示的。
之后通过计算选择液压器件，进而再完成系统的设计和调试。这个过程中，原理图的绘制是关键的。它决定了一个设计系统的优劣。液压传动的应用性是很强的，比如装卸堆码机液压系统，它作为一种仓储机械，在现代化的仓库里利用它实现纺织品包、油桶、木桶等货物的装卸机械化工作。也可以应用在万能外圆磨床液压系统等生产实践中。这些系统的特点是功率比较大，生产的效率比较高，平稳性比较好。
