    电磁阀(Electromagnetic valve)是用电磁控制的工业设备,是用来控制流体的自动化基础元件,属于执行器,并不限于液压、气动。用在工业控制系统中调整介质的方向、流量、速度和其他的参数。电磁阀可以配合不同的电路来实现预期的控制,而控制的精度和灵活性都能够保证。电磁阀有很多种,不同的电磁阀在控制系统的不同位置发挥作用,常用的是单向阀、安全阀、方向控制阀、速度调节阀等。
     电磁阀里有密闭的腔,在不同位置开有通孔,每个孔连接不同的油管,腔中间是活塞,两面是两块电磁铁,哪面的磁铁线圈通电阀体就会被吸引到哪边,通过控制阀体的移动来开启或关闭不同的排油孔,而进油孔是常开的,液压油就会进入不同的排油管,然后通过油的压力来推动油缸的活塞,活塞又带动活塞杆,活塞杆带动机械装置。这样通过控制电磁铁的电流通断就控制了机械运动。
    适用于以下空压机:瑞典Atlas.Copco(阿特拉斯.科普柯),美国SULLAIR(寿力)、Ingersoll-Rand(英格索兰),英国CompAir(康普艾)、中国台湾FS(复盛)、登福GD(嘉顿丹佛) GardnerDenver、日本HITACHI(日立)、KOBELCO(神钢)、Iwata(岩田)、德国ECOAIR(艾高)、BOGE(宝驹/伯格)、KAESER(凯撒)、霸尔向阳(ROTORCOMP)、柳州LiUTEHCH(富达)、德国曼(MAN)、昆西、博莱特、施耐德日盛、优耐特斯、正力精工、斯可络、凌格风、锡压、飞和、维肯、玛泰、艾能、浪潮、开山、捷豹·····

    电磁阀从原理上分为三大类:
      1)直动式电磁阀:
      原理:通电时,电磁线圈产生电磁力把关闭件从阀座上提起,阀门打开;断电时,电磁力消失,弹簧把关闭件压在阀座上,阀门关闭。
      特点:在真空、负压、零压时能正常工作,但通径一般不过25mm。
      2)分步直动式电磁阀:
      原理:它是一种直动和先导式相结合的原理,当入口与出口没有压差时,通电后,电磁力直接把先导小阀和主阀关闭件依次向上提起,阀门打开。当入口与出口达到启动压差时,通电后,电磁力先导小阀,主阀下腔压力上升,上腔压力下降,从而利用压差把主阀向上推开;断电时,先导阀利用弹簧力或介质压力推动关闭件,向下移动,使阀门关闭。
      特点:在零压差或真空、高压时亦能可*动作,但功率较大,要求必须水平安装。
      3)先导式电磁阀:
      原理:通电时,电磁力把先导孔打开,上腔室压力迅速下降,在关 闭件周围形成上低下高的压差,流体压力推动关闭件向上移动,阀门打开;断电时,弹簧力把先导孔关闭,入口压力通过旁通孔迅速腔室在关阀件周围形成下低上高的压差,流体压力推动关闭件向下移动,关闭阀门。
      特点:流体压力范围上限较高,可任意安装(需定制)但必须满足流体压差条件。
      2、电磁阀从阀结构和材料上的不同与原理上的区别,分为六个分支小类:直动膜片结构、分步直动膜片结构、先导膜片结构、直动活塞结构、分步直动活塞结构、先导活塞结构。
      3、电磁阀按照功能分类:水用电磁阀、蒸汽电磁阀、制冷电磁阀、低温电磁阀、燃气电磁阀、消防电磁阀、氨用电磁阀、气体电磁阀、液体电磁阀、微型电磁阀、脉冲电磁阀、液压电磁阀 常开电磁阀、油用电磁阀、直流电磁阀、高压电磁阀、防爆电磁阀等。
     电磁阀是由电磁线圈和磁芯组成,是包含一个或几个孔的阀体。当线圈通电或断电时,磁芯的运转将导致流体通过阀体或被切断,以达到改变流体方向的目的。电磁阀的电磁部件由固定铁芯、动铁芯、线圈等部件组成;阀体部分由滑阀芯、滑阀套、弹簧底座等组成。电磁线圈被直接安装在阀体上,阀体被封闭在密封管中,构成一个简洁、紧凑的组合。我们在生产中常用的电磁阀有二位三通、二位四通、二位五通等。这里先说说二位的含义:对于电磁阀来说就是带电和失电,对于所控制的阀门来说就是开和关。
      电磁阀的故障将直接影响到切换阀和调节阀的动作,常见的故障有电磁阀不动作,应从以下几方面排查:
      1、电磁阀接线头松动或线头脱落,电磁阀不得电,可紧固线头。
      2、电磁阀线圈烧坏,可拆下电磁阀的接线,用万用表测量,如果开路,则电磁阀线圈烧坏。原因有线圈受潮,引起绝缘不好而漏磁,造成线圈内电流过大而烧毁,因此要防止雨水进入电磁阀。此外,弹簧过硬,反作用力过大,线圈匝数太少,吸力不够也可使得线圈烧毁。紧急处理时,可将线圈上的手动按钮由正常工作时的“0”位打到“1”位,使得阀打开。
      3、电磁阀卡住:电磁阀的滑阀套与阀芯的配合间隙很小(小于0.008mm),一般都是单件装配,当**械杂质带入或润滑油太少时,很容易卡住。处理方法可用钢丝从头部小孔捅入,使其弹回。根本的解决方法是要将电磁阀拆下,取出阀芯及阀芯套,用CCI4清洗,使得阀芯在阀套内动作灵活。拆卸时应注意各部件的装配顺序及外部接线位置,以便重新装配及接线正确,还要检查油雾器喷油孔是否堵塞,润滑油是否足够。
      4、漏气:漏气会造成空气压力不足,使得强制阀的启闭困难,原因是密封垫片损坏或滑阀磨损而造成几个空腔窜气。在处理切换系统的电磁阀故障时,应选择适当的时机,等该电磁阀处于失电时进行处理,若在一个切换间隙内处理不完,可将切换系统暂停,从容处理。
    Electromagnetic valve, Electromagnetic valve) is to use Electromagnetic control of industrial equipment, is used to control fluid automation of basic components, belonging to the actuator, is not limited to hydraulic, pneumatic. In the industrial control system, is used to adjust the direction of the medium, flow, speed and other parameters. Solenoid valve with different circuit to achieve the desired control, and can guarantee control precision and flexibility. Solenoid valve, electromagnetic valve, there are many kinds of different work in different locations in the control system, the most commonly used is a one-way valve, safety valve, direction valve, speed regulator, etc.
    Solenoid valve has closed cavity, opened a hole in different position, each hole connect different tubing, cavity piston is among, two sides are two electromagnets, which face the magnet coil electricity will be attracted to the body which side, by controlling the movement of the body to open or close the different discharge of oil hole, and the oil hole is always open, hydraulic fluid will enter the different oil drain, and then through the oil pressure to push the cylinder piston, the piston drives the piston rod, piston rod drive mechanism. Electric current to break by controlling the electromagnet is to control the mechanical movement.

    Solenoid valve in principle can be divided into three categories:
    1) direct acting solenoid valve:
    Principle: electricity, electromagnetic coil to produce electromagnetic force to close a file from the seat, the valve is open; Power, the electromagnetic force disappears, press on the seat, spring to close the valve closed.
    Features: in a vacuum and negative pressure, can work properly when the zero pressure, but size is generally not more than 25 mm.
    2) by direct acting solenoid valve:
    Principle: it is a direct acting and pilot operated combination principle, when the inlet and outlet no pressure difference, after electrify, the electromagnetic force directly to the pilot valve and main valve closure in turn lift, the valve open. When the differential pressure of the inlet and outlet at startup, after electrify, the electromagnetic pi
