卸荷溢流阀
先导式卸荷式溢流阀，电磁卸荷溢流阀用于带蓄能器的液压系统，使泵自动卸荷或加载;用于高低压双泵系统，使低压泵卸荷。DAW型阀利用电磁阀使系统卸荷。
先导式溢流阀主要由先导阀、带主阀芯的主阀和单向阀组成，电磁溢流阀还在先导阀上装有电磁阀。通径10mm的先导式卸荷阀的单向阀在主体阀内;而通径25mm和32mm的先导式卸荷阀的单向阀在主阀底下的连接板内。溢流阀应用于有蓄能器的液压系统中时，主要作用是给蓄能器补油:应用于高、低压双泵系统中时，可使低压泵卸荷。而DAW型阀利用其上的电磁阀，还可以在任何压力下使系统卸荷。

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。

目前钢筋切断机的主要有两种形式,一种是机械式切断机, 一种是液压式切断
机,机械式切断机主要利用凸轮的运动来切断钢筋,液压式切断机主要利用液压系统为机器提供动力进行工作。 这两种切断机相比较而言,液压式切断机优势较为明显,性能稳定 、噪音小,这些优势给液压切断机的广泛应用创造力有利条件。 就目前的发展趋势来看,液压切断机克服了过去的一些缺点,剪姆率、速度、误差等性能有了大幅提高。本设计对切断机的液压系统泵站进行了设计,系统采用电磁换向阀、叠加式减压阀 压力传感器等措施,使该液压系统运行平稳、能耗小、安全可靠性高。

由于液压技术有很多优点，从一般传动到精密控制，都得到了广泛的应用。在机械工业中，目前机床传动系统有85%采用液压传动与控制，如磨、铣、刨、拉、及组合车床等；在工程机械中，普遍采用了液压传动，如挖掘机、轮胎装载机、汽车起动机、履带推土机，自行式铲运机、平地机、压路机等；在农业机械中，目前已用于联合收割机、拖拉机、工具悬挂系统；在汽车工业中，液压制动、液压自卸、消防云梯等都得到广泛应用；在冶金工业中，如电炉控制系统、轧钢机的控制系统、手炉装料、转炉控制，高炉控制等；在轻纺工业中，诸如注塑机、橡胶硫化机、造纸机、印刷机、纺织机械等；在船舶工业中，如全液压挖泥船、打捞船、采油平台、翼船、气垫船及船舶辅机等。一切工程领域，凡是有机械设备的场合，均可采用液压技术，使用领域和设备越来越宽、越来越多

折弯机是一种能够对薄板进行折弯的机器，其结构主要包括支架、工作台和夹紧板，工作台置于支架上，工作台由底座和压板构成，底座通过铰链与夹紧板相连，底座由座壳、线圈和盖板组成，线圈置于座壳的凹陷内，凹陷顶部覆有盖板。使用时由导线对线圈通电，通电后对压板产生引力，从而实现对压板和底座之间薄板的夹持。由于采用了电磁力夹持，使得压板可以做成多种工件要求，而且可对有侧壁的工件进行加工，操作上也十分简便。
