PARKER電磁換向閥D91VW001E2NJW91派克是用電磁控制的工業(yè)設(shè)備，是用來控制流體的自動化基礎(chǔ)元件，屬于執(zhí)行器，并不限于液壓、氣動。用在工業(yè)控制系統(tǒng)中調(diào)整介質(zhì)的方向、流量、速度和其他的參數(shù)。電磁閥可以配合不同的電路來實現(xiàn)預(yù)期的控制，而控制的精度和靈活性都能夠保證。電磁閥有很多種，不同的電磁閥在控制系統(tǒng)的不同位置發(fā)揮作用，常用的是單向閥、安全閥、方向控制閥、速度調(diào)節(jié)閥等。工作原理

電磁閥里有密閉的腔，在不同位置開有通孔，每個孔連接不同的油管，腔中間是活塞，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會被吸引到哪邊，通過控制閥體的移動來開啟或關(guān)閉不同的排油孔，而進(jìn)油孔是常開的，液壓油就會進(jìn)入不同的排油管，然后通過油的壓力來推動油缸的活塞，活塞又帶動活塞桿，活塞桿帶動機械裝置。這樣通過控制電磁鐵的電流通斷就控制了機械運動。
