的工作原理

電磁(ci)(ci)閥里(li)有密閉的(de)(de)(de)腔，在(zai)不同(tong)位(wei)置開有通(tong)孔(kong)(kong)，每個孔(kong)(kong)連接(jie)不同(tong)的(de)(de)(de)油(you)(you)管，腔中(zhong)間是活(huo)塞(sai)，兩面(mian)是兩塊電磁(ci)(ci)鐵，哪(na)面(mian)的(de)(de)(de)磁(ci)(ci)鐵線圈通(tong)電閥體就會(hui)被吸引到哪(na)邊(bian)，通(tong)過(guo)控(kong)制(zhi)閥體的(de)(de)(de)移動(dong)(dong)來開啟(qi)或關閉不同(tong)的(de)(de)(de)排(pai)油(you)(you)孔(kong)(kong)，而進(jin)油(you)(you)孔(kong)(kong)是常開的(de)(de)(de)，液壓油(you)(you)就會(hui)進(jin)入不同(tong)的(de)(de)(de)排(pai)油(you)(you)管，然后通(tong)過(guo)油(you)(you)的(de)(de)(de)壓力來推動(dong)(dong)油(you)(you)缸的(de)(de)(de)活(huo)塞(sai)，活(huo)塞(sai)又帶(dai)動(dong)(dong)活(huo)塞(sai)桿(gan)，活(huo)塞(sai)桿(gan)帶(dai)動(dong)(dong)機(ji)械(xie)(xie)裝置。這樣通(tong)過(guo)控(kong)制(zhi)電磁(ci)(ci)鐵的(de)(de)(de)電流通(tong)斷(duan)就控(kong)制(zhi)了機(ji)械(xie)(xie)運動(dong)(dong)。

電磁閥從(cong)原理(li)上分為三大類：

先導式電磁閥

原理：通(tong)電(dian)時，電(dian)磁力把(ba)先(xian)導孔打(da)開，上(shang)腔室壓(ya)(ya)(ya)力迅速(su)下降，在(zai)關(guan)(guan) 閉(bi)件(jian)(jian)周圍(wei)形成上(shang)低下高的(de)壓(ya)(ya)(ya)差(cha)，流體(ti)壓(ya)(ya)(ya)力推動關(guan)(guan)閉(bi)件(jian)(jian)向(xiang)上(shang)移動，閥門打(da)開；斷電(dian)時，彈簧(huang)力把(ba)先(xian)導孔關(guan)(guan)閉(bi)，入口(kou)壓(ya)(ya)(ya)力通(tong)過旁通(tong)孔迅速(su)腔室在(zai)關(guan)(guan)閥件(jian)(jian)周圍(wei)形成下低上(shang)高的(de)壓(ya)(ya)(ya)差(cha)，流體(ti)壓(ya)(ya)(ya)力推動關(guan)(guan)閉(bi)件(jian)(jian)向(xiang)下移動，關(guan)(guan)閉(bi)閥門。

德(de)國GSR高壓電磁(ci)閥的(de)工作(zuo)原(yuan)理(li)是什么？

直動式電磁閥

原理(li)：通電(dian)時，電(dian)磁(ci)線圈產生電(dian)磁(ci)力(li)把(ba)關閉件(jian)從閥(fa)座上(shang)提起，閥(fa)門打開；斷電(dian)時，電(dian)磁(ci)力(li)消失，彈簧把(ba)關閉件(jian)壓在(zai)閥(fa)座上(shang)，閥(fa)門關閉。

特點：在(zai)真空、負(fu)壓(ya)(ya)、零(ling)壓(ya)(ya)時能正常工作，但通徑(jing)一般(ban)不超過(guo)25mm。

分步直動式電磁閥

原(yuan)理：它是一種直(zhi)動和先(xian)導式相結合(he)的原(yuan)理，當入口與(yu)出口沒有壓(ya)差時(shi)，通(tong)電(dian)后，電(dian)磁力(li)(li)直(zhi)接把(ba)(ba)先(xian)導小(xiao)閥(fa)(fa)和主(zhu)閥(fa)(fa)關閉件(jian)依次向上提起(qi)，閥(fa)(fa)門(men)打開。當入口與(yu)出口達(da)到啟動壓(ya)差時(shi)，通(tong)電(dian)后，電(dian)磁力(li)(li)先(xian)導小(xiao)閥(fa)(fa)，主(zhu)閥(fa)(fa)下腔壓(ya)力(li)(li)上升，上腔壓(ya)力(li)(li)下降，從而利(li)用壓(ya)差把(ba)(ba)主(zhu)閥(fa)(fa)向上推(tui)開；斷(duan)電(dian)時(shi)，先(xian)導閥(fa)(fa)利(li)用彈簧(huang)力(li)(li)或介質壓(ya)力(li)(li)推(tui)動關閉件(jian)，向下移動，使閥(fa)(fa)門(men)關閉。

特點：在零壓(ya)差或(huo)真空、高(gao)壓(ya)時亦(yi)能(neng)動作(zuo)，但功率較大，要(yao)求(qiu)必須水平安(an)裝。

特點：

1、流體(ti)壓(ya)力范圍上限較高，可任意安裝（需定制）但必須(xu)滿足流體(ti)壓(ya)差(cha)條件。

2、電磁閥(fa)從閥(fa)結(jie)(jie)(jie)(jie)構和材(cai)料(liao)上的不同(tong)與(yu)原理上的區別，分為(wei)六個分支(zhi)小類(lei)：直動(dong)膜(mo)片結(jie)(jie)(jie)(jie)構、分步直動(dong)膜(mo)片結(jie)(jie)(jie)(jie)構、先導膜(mo)片結(jie)(jie)(jie)(jie)構、直動(dong)活塞(sai)結(jie)(jie)(jie)(jie)構、分步直動(dong)活塞(sai)結(jie)(jie)(jie)(jie)構、先導活塞(sai)結(jie)(jie)(jie)(jie)構。
