博世力士樂(lè)比例壓力流量閥
博世力士樂(lè)比例壓力流量閥用來(lái)控制流體方向的自動(dòng)化基礎(chǔ)元件,屬于執(zhí)行器;通常用于機(jī)械控制和工業(yè)閥門(mén)上面,對(duì)介質(zhì)方向進(jìn)行控制,從而達(dá)到對(duì)閥門(mén)開(kāi)關(guān)的控制。工作原理電磁閥里有密閉的腔,在不同位置開(kāi)有通孔,每個(gè)孔都通向不同的油管,腔中間是閥,兩面是兩塊電磁鐵,哪面的磁鐵線圈通電閥體就會(huì)被吸引到哪邊,通過(guò)控制閥體的移動(dòng)來(lái)?yè)踝』蚵┏霾煌呐庞偷目?,而進(jìn)油孔是常開(kāi)的,液壓油就會(huì)進(jìn)入不同的排油管,然后通過(guò)油的壓力來(lái)推動(dòng)油缸的活塞,活塞又帶動(dòng)活塞桿,活塞桿帶動(dòng)機(jī)械裝置動(dòng)。這樣通過(guò)控制電磁鐵的電流通斷就控制了機(jī)械運(yùn)動(dòng)。
