力(li)士樂電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)它由(you)閥(fa)體、閥(fa)罩(zhao)、電(dian)(dian)(dian)磁(ci)(ci)(ci)組(zu)件、彈(dan)簧(huang)(huang)及密封結構等部(bu)(bu)件組(zu)成,動(dong)(dong)鐵(tie)芯(xin)底部(bu)(bu)的(de)(de)密封塊(kuai)借助彈(dan)簧(huang)(huang)的(de)(de)壓力(li)將閥(fa)體進(jin)氣(qi)(qi)口(kou)關(guan)閉(bi)。通(tong)電(dian)(dian)(dian)后(hou),電(dian)(dian)(dian)磁(ci)(ci)(ci)鐵(tie)吸(xi)合,動(dong)(dong)鐵(tie)芯(xin)上(shang)部(bu)(bu)帶彈(dan)簧(huang)(huang)的(de)(de)密封塊(kuai)把排氣(qi)(qi)口(kou)關(guan)閉(bi),氣(qi)(qi)流(liu)(liu)(liu)從進(jin)氣(qi)(qi)口(kou)進(jin)入膜(mo)(mo)(mo)頭(tou),起到控制(zhi)(zhi)(zhi)(zhi)(zhi)作用(yong)(yong)(yong)。當失(shi)電(dian)(dian)(dian)時(shi),電(dian)(dian)(dian)磁(ci)(ci)(ci)力(li)消(xiao)失(shi),動(dong)(dong)鐵(tie)芯(xin)在(zai)彈(dan)簧(huang)(huang)力(li)作用(yong)(yong)(yong)下離開(kai)固(gu)定(ding)鐵(tie)芯(xin),向下移動(dong)(dong),將排氣(qi)(qi)口(kou)打開(kai),堵住進(jin)氣(qi)(qi)口(kou),膜(mo)(mo)(mo)頭(tou)氣(qi)(qi)流(liu)(liu)(liu)經排氣(qi)(qi)口(kou)排出,膜(mo)(mo)(mo)片恢復原來位置(zhi)。在(zai)我(wo)(wo)(wo)們的(de)(de)制(zhi)(zhi)(zhi)(zhi)(zhi)氧(yang)(yang)設備中,在(zai)透平膨脹機進(jin)口(kou)薄膜(mo)(mo)(mo)調節閥(fa)的(de)(de)緊急切斷等處有應用(yong)(yong)(yong)。Rexroth四(si)通(tong)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)在(zai)我(wo)(wo)(wo)們的(de)(de)生(sheng)產(chan)中應用(yong)(yong)(yong)也很多,其(qi)工作原理如下:當有電(dian)(dian)(dian)流(liu)(liu)(liu)通(tong)過(guo)線圈(quan)時(shi),產(chan)生(sheng)勵磁(ci)(ci)(ci)作用(yong)(yong)(yong),固(gu)定(ding)鐵(tie)芯(xin)吸(xi)合動(dong)(dong)鐵(tie)芯(xin),動(dong)(dong)鐵(tie)芯(xin)帶動(dong)(dong)滑閥(fa)芯(xin)并壓縮(suo)彈(dan)簧(huang)(huang),改變了滑閥(fa)芯(xin)的(de)(de)位置(zhi),從而改變了流(liu)(liu)(liu)體的(de)(de)方向。當線圈(quan)失(shi)電(dian)(dian)(dian)時(shi),依靠彈(dan)簧(huang)(huang)的(de)(de)彈(dan)力(li)推(tui)動(dong)(dong)滑閥(fa)芯(xin),頂回(hui)動(dong)(dong)鐵(tie)芯(xin),使流(liu)(liu)(liu)體按原來的(de)(de)方向流(liu)(liu)(liu)動(dong)(dong)。在(zai)我(wo)(wo)(wo)們制(zhi)(zhi)(zhi)(zhi)(zhi)氧(yang)(yang)生(sheng)產(chan)中,分(fen)子篩切換(huan)系(xi)統強制(zhi)(zhi)(zhi)(zhi)(zhi)閥(fa)的(de)(de)開(kai)關(guan)就是通(tong)過(guo)二(er)位四(si)通(tong)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)來控制(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de),氣(qi)(qi)流(liu)(liu)(liu)分(fen)別供至強制(zhi)(zhi)(zhi)(zhi)(zhi)閥(fa)的(de)(de)活塞兩端。從而來控制(zhi)(zhi)(zhi)(zhi)(zhi)強制(zhi)(zhi)(zhi)(zhi)(zhi)閥(fa)的(de)(de)啟(qi)閉(bi)。

1、技術參數:
1)根據介質流向要求及管道連接方式選擇閥門通口及型號;
2)根據流量和閥門Kv值選定公稱通徑,也可選同管道內徑;
3)工作壓差:zui低工作壓差在0.04Mpa以上是可選用間接先導式;zui低工作壓差接近或小于零的必須選用直動式或分步直接式。
2、環境條件
1)環境的zui高和zui低溫度應選在允許范圍之內;
2)環境中相對濕度高及有水滴雨淋等場合,應選防水電磁閥;
3)環境中經常有振動,顛簸和沖擊等場合應選特殊品種,例如船用電磁閥;
4)在有腐蝕性或爆炸性環境中的使用應優先根據安全性要求選用耐發蝕型;
5)環境空間若受限制,需選用多功能電磁閥,因其省去了旁路及三只手動閥且便于在線維修。
3、電源條件
1)根據供電電源種類,分別選用交流和直流電磁閥。一般來說交流電源取用方便;
2)電壓規格用盡量優先選用AC220V.DC24V;
3)電源電壓波動通常交流選用+%10%.-15%,直流允許±%10左右,如若超差,須采取穩壓措施;
4)應(ying)根(gen)據電源容(rong)量選擇額定電流(liu)和消(xiao)耗功率。須注(zhu)意交流(liu)起動時VA值較高,在容(rong)量不足時應(ying)優先(xian)選用間(jian)接導式(shi)電磁閥。
