FESTO雙電控電磁閥JMC-4-1/4@FESTO螺紋氣缸
雙電(dian)(dian)(dian)(dian)(dian)控電(dian)(dian)(dian)(dian)(dian)磁閥： 也叫雙線(xian)(xian)(xian)圈電(dian)(dian)(dian)(dian)(dian)磁閥，通(tong)常不帶(dai)電(dian)(dian)(dian)(dian)(dian)。一個(ge)線(xian)(xian)(xian)圈帶(dai)電(dian)(dian)(dian)(dian)(dian)1個(ge)脈沖(chong)后，線(xian)(xian)(xian)圈失電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)磁閥動作，到一種氣路(lu)(lu)。 另一個(ge)線(xian)(xian)(xian)圈帶(dai)電(dian)(dian)(dian)(dian)(dian)1個(ge)脈沖(chong)后，線(xian)(xian)(xian)圈失電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)磁閥動作，氣路(lu)(lu)切換(huan)。
雙電控電磁閥就像雙作用氣缸一樣，不帶彈簧復位，兩個線圈只能有一個勵磁，一推一拉的工作方式
單電控(kong)電磁(ci)閥(fa)就(jiu)像單作(zuo)用(yong)氣缸一(yi)(yi)樣，帶彈簧(huang)(huang)復(fu)位，帶電一(yi)(yi)拉(線圈勵磁(ci))，失(shi)電一(yi)(yi)推(彈簧(huang)(huang)復(fu)位)的工(gong)作(zuo)方式
應該(gai)是每一(yi)種狀態都需要電源驅動，就是斷電維持在原(yuan)狀態
雙電(dian)(dian)控電(dian)(dian)磁閥有三位(wei)(wei)，存在中(zhong)位(wei)(wei)，在中(zhong)位(wei)(wei)輸(shu)出(chu)端(duan)沒有動力能出(chu)現；單電(dian)(dian)控電(dian)(dian)磁閥重(zhong)油兩位(wei)(wei)，沒有中(zhong)位(wei)(wei)！
雙(shuang)控(kong)電(dian)磁閥(fa)為(wei)三位(wei)(wei)閥(fa)，無(wu)信號(hao)(hao)時為(wei)中間(jian)位(wei)(wei)置(zhi)，哪(na)端有有信號(hao)(hao)，活(huo)塞到哪(na)里，管(guan)路導通，失(shi)電(dian)后活(huo)塞又回中間(jian)位(wei)(wei)置(zhi)。單控(kong)電(dian)磁閥(fa)只有兩個位(wei)(wei)置(zhi)，一(yi)個是無(wu)信號(hao)(hao)時在彈簧(huang)作用下的位(wei)(wei)置(zhi)。另一(yi)個則是有信號(hao)(hao)時的電(dian)磁作用下的位(wei)(wei)置(zhi)。
電控是(shi)(shi)不是(shi)(shi)就(jiu)是(shi)(shi)偶們所說的(de)(de)雙線(xian)(xian)(xian)圈(quan)(quan)啊，這個與單(dan)線(xian)(xian)(xian)圈(quan)(quan)zui大的(de)(de)區別(bie)就(jiu)是(shi)(shi)一個雙線(xian)(xian)(xian)圈(quan)(quan)一個單(dan)線(xian)(xian)(xian)圈(quan)(quan)。在制造上的(de)(de)表(biao)現(xian)就(jiu)是(shi)(shi)雙線(xian)(xian)(xian)圈(quan)(quan)由于兩側(ce)通過(guo)電磁吸力來實(shi)現(xian)閥體內部活(huo)塞桿的(de)(de)移(yi)動來產生(sheng)狀態轉換因此不需要初始(shi)彈(dan)簧，而單(dan)線(xian)(xian)(xian)圈(quan)(quan)的(de)(de)電磁閥需要安裝初始(shi)彈(dan)簧。
可以(yi)這(zhe)樣類比，單線(xian)圈(quan)電磁(ci)閥(fa)就如同氣動(dong)薄膜調節閥(fa)的(de)執行器，雙線(xian)圈(quan)電磁(ci)閥(fa)就如同雙作用的(de)汽(qi)缸(gang)
