溢流阀是一种液压压力控制阀，在液压设备中主要起定压溢流作用，稳压，系统卸荷和安全保护作用。
定压溢流作用：在定量泵节流调节系统中，定量泵提供的是恒定流量。当系统压力增大时，会使流量需求减小。此时溢流阀开启，使多余流量溢回油箱，保证溢流阀进口压力，即泵出口压力恒定（阀口常随压力波动开启）。


稳压作用：溢流阀串联在回油路上，溢流阀产生背压，运动部件平稳性增加。
系统卸荷作用：在溢流阀的遥控口串接溢小流量的电磁阀，当电磁铁通电时，溢流阀的遥控口通油箱，此时液压泵卸荷。溢流阀此时作为卸荷阀使用。
安全保护作用：系统正常工作时，阀门关闭。只有负载超过规定的极限（系统压力超过调定压力）时开启溢流，进行过载保护，使系统压力不再增加（通常使溢流阀的调定压力比系统高工作压力高10%～20%）。
实际应用中一般有：作卸荷阀用，作远程调压阀，作高低压多级控制阀，作顺序阀，用于产生背压（串在回油路上）。


溢流阀一般有两种结构：1、直动型溢流阀 。2、先导式溢流阀。
对溢流阀的主要要求：调压范围大，调压偏差小，压力振摆小，动作灵敏，过载能力大，噪声小。
先导型溢流阀的导阀部分结构尺寸较小，调压弹簧不必很强，因此压力调整比较轻便。但因先导型溢流阀要在先导阀和主阀都动作后才能起控制作用，因此反应不如直动型溢流阀灵敏。
与三节同心结构相比，二节同心结构的特点是：①主阀芯仅与阀套和主阀座有同心度要求，免去了与阀盖的配合，故结构简单，加工和装配方便。②过流面积大，在相同流量的情况下，主阀开启高度小；或者在相同开启高度的情况下，其通流能力大，因此，可做得体积小、重量轻。③主阀芯与阀套可以通用化，便于组织批量生产。

    
比例溢流阀的压力等级要与系统所需要的压力相适应，以确保较好的分辨率。 系统需要调节的高压力是180bar，则比例溢流阀的压力等级应该是210左右 .不应该是315bar等太高的等级。原则是尽量使比例溢流阀的高控制压力略大于系统所需要的高压力。
　　先使系统安全阀全开，比例溢流阀输入电流为零，再起泵。然后保持安全阀为零，给比例阀输入大电流 .慢慢调节手调安全阀的手柄，使系统压力逐步上升，将比例阀输入电流降下来，直到系统需要的高压力，记录对应当输入电流数值。这就是系统要求的高压力说对应的电流，如果用计算机控制或用信号发生器输入，将这个电流为输入电流的限制值。

1）电磁溢流阀原理上，一般是由先导式溢流阀加上一个2位2通电磁阀组成。
2）这个电磁阀实际上由两部分组成：2位2通的液压阀部分，加上一个电磁铁。2位2通阀是开通，还是关闭，是由电磁铁推动阀芯运动来实现的。有的阀电磁铁通电时打开，有的阀电磁铁断电时打开，萝目青菜个人各爱（根据系统要求选择）。也就是说，电磁阀这里有一条通路一头与先导溢流阀的某个部位相连，另一头通过油管与油箱相连。通过操作电磁铁可以让先导溢流阀的某个部位或者与油箱相通，或者不与油箱相通。
 
3）先导溢流阀的主阀上腔压力，是由先导阀加于控制的。如果先导阀正常工作，即主阀上腔有先导阀规定的压力，则整个溢流阀就会在系统压力到达调定压力时其主阀口打开一定的开度，一方面能将系统多余流量流回油箱，另一方面又能维持系统的压力为先导阀的调定值。可见，先导阀主要管压力，主阀服从先导阀的领导，在先导阀动作时将主阀口开到合适大小，正好将多余流量流出去，又不影响系统压力。

一、液压传动技术的应用
液压传动技术在近代工业制造中的应用
液压传动有许多突出的优点，因此它的应用非常广泛，如一般工业用的塑料加工机械、压力机械、机床等，行走机械中的工程机械、建筑机械、农业机械、汽车等;钢铁工业用的冶金机械、提升装置、轧辊调整装置等;土木水利工程用的防洪闸门及堤坝装置、河床升降装置、桥梁操纵机构等，发电厂涡轮机调速装置、发电厂等等。

二、液压传动技术的原理与特点
1、液压传动的介绍
液压传动是用液体作为工作介质来传递能量和进行控制的传动方式。液压传动和气压传动并称为流体传动，是根据17世纪帕斯卡提出的液体静压力传动原理而发展起来的一门新兴技术，是工农业生产中应用广泛的技术。
2、液压传动的优点
(1)体积小、重量轻，因此惯性力较小，当突然过载或停车时，不会发生大的冲击，
(2)能在给定范围内平稳的自动调节牵引速度，并可实现无极调速;
(3)换向容易，在不改变电机旋转方向的情况下，可以较方便地实现工作机构旋转和直线往复运动的转换;
(4)液压泵和液压马达之间用油管连接，在空间布置上彼此不受严格限制;
(5) 由于采用油液为工作介质，元件相对运动表面间能自行润滑，磨损小，使用寿命长;
(6)操纵控制简便，自动化程度高;
(7)容易实现过载保护。
液压传动有许多突出的优点，因此它的应用非常广泛，如一般工业用的塑料加工机械、压力机械、机床等，行走机械中的工程机械、建筑机械、农业机械、汽车等，钢铁工业用的冶金机械、提升装置、轧辊调整装置等，土木水利工程用的防洪闸门及堤坝装置、河床升降装置、桥粱操纵机构等;发电厂涡轮机调速装置等等，船舶用的甲板起重机械、船头门、舱壁阀、船尾推进器等，特殊技术用的控制装置、测量浮标、升降旋转舞台等。
3、液压传动的基本原理
液压传动的基本原理是在密闭的容器内，利用有压力的油液作为工作介质来实现能量转换和传递动力的。其中的液体称为工作介质，一般为矿物油，它的作用和机械传动中的皮带、链条和齿轮等传动元件相类似。液压传动是利用帕斯卡原理!帕斯卡原理是大概就是:在密闭环境中，向液体施加一个力，这个液体会向各个方向传递这个力!力的大小不变!液压传动就是利用这个物理性质，向一个物体施加一个力，利用帕斯卡原理使这个力变大!从而起到举起重物的效果!
液压传动在阀门行业也得到很大的应用,如阀门的机床制造加工设备、阀门]液压试验设备、阀门的液压传动装置等。

三、液压传动系统的组成
1、液压动力原件
将动力装置的机械能转换成为液压能的装置，其作用是为液压传动系统提供压力油,是液压传动系统的动力源。例如液压泵。
1.1液压泵
液压泵是液压系统的动力元件，其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。
1.2齿轮泵
齿轮泵即依靠密封在个壳体中的两个或两个以上齿轮,在相互啮合过程中所产生的工作空间容积变化来输送液体的泵。齿轮泵的概念是很简单的，即它的基本形式就是两个尺寸相同的齿轮在一个紧密配合的壳体内相互啮合旋转，这个壳体的内部类似“8”字形，两个齿轮装在里面,齿轮的外径及两侧与壳体紧密配合。来自于挤出机的物料在吸入口进入两个齿轮中间，并充满这一空间，随着齿的旋转沿壳体运动，*后在两齿啮合时排出。困油现象齿轮泵要平稳工作，齿轮啮合的重合度必须大于1, 于是总有两对齿轮同时啮合, :并有一部分油液被围困在两对轮齿所围成的封闭容腔之间。这个封闭的容腔开始随着
齿轮的转动逐渐减小，以后又逐渐加大。封闭腔容积的减小会使被困油液受挤压而产生很高的压力，并且从缝隙中挤出，导致油液发热，并致使机件受到额外的负载，而封闭腔容积的增大又造成局部真空，使油液中溶解的气体分离，产生气穴现象。这些都将产生强烈的振动和噪音，这就是齿轮泵的困意现象。
危害：径向不平衡力很大时能使轴弯曲，齿顶与壳体接触，同时加速轴承的磨损，降低轴承的寿命。
消除困油现象方法:通常是在两侧盖板上开卸荷槽，使封闭腔容积诚小时通过左边的卸荷槽与压油腔相通，容积增大时通过右边的卸荷槽与吸油腔相通。
1.3叶片泵
叶片泵即通过叶轮的旋转，将动力机的机械能转换为水能(势能、动能、压能)的水力机械。
叶片泵转子旋转时，叶片在离心力和压力油的作用下，尖部紧贴在定子内表面上。这样两个叶片与转子和定子内表面所构成的工作容积，先由小到大吸油后再由大到小排油，叶片旋转一周时，完成两次吸油与排油。
1.4柱塞泵
柱塞泵即利用柱塞在泵缸体内往复运动，使柱塞与泵壁间形成容积改变，反复吸入和排;出液体并增高其压力的泵。
柱塞泵是液压系统的一个重要装置。它依靠柱塞在缸体中往复运动，使密封工作容腔的容积发生变化来实现吸油、压油。柱塞泵具有额定压力高、结构紧凑、效率高和流量调节方便等优点，被广泛应用于高压、大流量和流量需要调节的场合，诸如液压机、工程机械和船舶中。
