德國寶德電磁閥92004665的工作原理：

德國寶(bao)德電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)用(yong)于(yu)控制(zhi)液(ye)壓(ya)(ya)(ya)流(liu)(liu)動(dong)方向，工廠的(de)(de)(de)機(ji)械裝置一般都由液(ye)壓(ya)(ya)(ya)鋼控制(zhi)，所以就會(hui)(hui)用(yong)到電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)。電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)的(de)(de)(de)工作原(yuan)理(li)，電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)里(li)有(you)密閉的(de)(de)(de)腔(qiang)，在(zai)的(de)(de)(de)不(bu)(bu)同(tong)(tong)(tong)位(wei)置開(kai)有(you)通孔，每個孔都通向不(bu)(bu)同(tong)(tong)(tong)的(de)(de)(de)油(you)(you)管(guan)，腔(qiang)中間是(shi)(shi)閥(fa)(fa)(fa)(fa)，兩面是(shi)(shi)兩塊電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)鐵(tie)(tie)，哪面的(de)(de)(de)磁(ci)(ci)(ci)鐵(tie)(tie)線圈(quan)通電(dian)(dian)(dian)(dian)(dian)閥(fa)(fa)(fa)(fa)體(ti)(ti)就會(hui)(hui)被吸引到哪邊，通過(guo)控制(zhi)閥(fa)(fa)(fa)(fa)體(ti)(ti)的(de)(de)(de)移動(dong)來(lai)檔住或漏(lou)出不(bu)(bu)同(tong)(tong)(tong)的(de)(de)(de)排油(you)(you)的(de)(de)(de)孔，而(er)(er)進(jin)(jin)油(you)(you)孔是(shi)(shi)常開(kai)的(de)(de)(de)，液(ye)壓(ya)(ya)(ya)油(you)(you)就會(hui)(hui)進(jin)(jin)入不(bu)(bu)同(tong)(tong)(tong)的(de)(de)(de)排油(you)(you)管(guan)，然后(hou)通過(guo)油(you)(you)的(de)(de)(de)壓(ya)(ya)(ya)力(li)(li)來(lai)推動(dong)油(you)(you)剛的(de)(de)(de)活(huo)(huo)(huo)塞，活(huo)(huo)(huo)塞又(you)帶動(dong)活(huo)(huo)(huo)塞桿，活(huo)(huo)(huo)塞竿帶動(dong)機(ji)械裝置動(dong)。這樣通過(guo)控制(zhi)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)鐵(tie)(tie)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)就控制(zhi)了機(ji)械運動(dong)。上面說得是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)的(de)(de)(de)普通原(yuan)理(li)實際(ji)上，根據流(liu)(liu)過(guo)介質(zhi)的(de)(de)(de)溫度，壓(ya)(ya)(ya)力(li)(li)等情況，比(bi)如管(guan)道有(you)壓(ya)(ya)(ya)力(li)(li)和自流(liu)(liu)狀(zhuang)(zhuang)態無壓(ya)(ya)(ya)力(li)(li)。電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)的(de)(de)(de)工作原(yuan)理(li)是(shi)(shi)不(bu)(bu)同(tong)(tong)(tong)的(de)(de)(de)。比(bi)如在(zai)自流(liu)(liu)狀(zhuang)(zhuang)態下(xia)需要(yao)零(ling)壓(ya)(ya)(ya)啟(qi)動(dong)的(de)(de)(de)，就是(shi)(shi)通電(dian)(dian)(dian)(dian)(dian)后(hou)，線圈(quan)整個把閘體(ti)(ti)吸起(qi)(qi)來(lai)。而(er)(er)有(you)壓(ya)(ya)(ya)力(li)(li)狀(zhuang)(zhuang)態的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)，則(ze)是(shi)(shi)線圈(quan)通電(dian)(dian)(dian)(dian)(dian)后(hou)吸出插在(zai)閘體(ti)(ti)上的(de)(de)(de)一個銷子(zi)，用(yong)流(liu)(liu)體(ti)(ti)自身的(de)(de)(de)壓(ya)(ya)(ya)力(li)(li)把閘體(ti)(ti)頂起(qi)(qi)來(lai)。這兩種(zhong)方式的(de)(de)(de)不(bu)(bu)同(tong)(tong)(tong)之處(chu)是(shi)(shi)，自流(liu)(liu)狀(zhuang)(zhuang)態的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)，因為(wei)線圈(quan)要(yao)吸起(qi)(qi)整個閘體(ti)(ti)，所以體(ti)(ti)積較大而(er)(er)帶壓(ya)(ya)(ya)狀(zhuang)(zhuang)態的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)，只需要(yao)吸起(qi)(qi)銷子(zi)，所以體(ti)(ti)積可(ke)以做的(de)(de)(de)比(bi)較小。

德國寶德電磁閥92004665的選型原則：

1、腐蝕性(xing)介質(zhi)：宜選(xuan)用(yong)塑料王電(dian)磁(ci)閥(fa)(fa)和全不銹(xiu)(xiu)鋼；對于強腐蝕的介 質(zhi)必須選(xuan)用(yong)隔離膜片式。中性(xing)介質(zhi)，也宜選(xuan)用(yong)鋁合金(jin)為閥(fa)(fa)殼材(cai)料的電(dian)磁(ci)閥(fa)(fa)，否則，閥(fa)(fa)殼中常有銹(xiu)(xiu)屑脫落，尤其(qi)是動作不頻繁(fan)的場(chang)合。氨(an)用(yong)閥(fa)(fa)則不能采用(yong)銅材(cai)。

2、爆炸(zha)性環(huan)境：必須選(xuan)用相(xiang)應(ying)防爆等(deng)級產品，露天安裝或粉塵多場合應(ying)選(xuan)用防水，防塵品種。

3、電磁閥(fa)公稱壓力應超過管內(nei)工(gong)作壓力。
