ATOS電磁(ci)閥的(de)主要(yao)分類
1、ATOS電磁閥從原理上分(fen)為三大類：
1）直動式電磁閥：
ATOS電(dian)磁閥(fa)(fa)原理：通電(dian)時，電(dian)磁線圈(quan)產(chan)生電(dian)磁力把(ba)關(guan)閉(bi)件從閥(fa)(fa)座上提起，閥(fa)(fa)門打開；斷電(dian)時，電(dian)磁力消(xiao)失，彈簧把(ba)關(guan)閉(bi)件壓在(zai)閥(fa)(fa)座上，閥(fa)(fa)門關(guan)閉(bi)。
ATOS電磁閥特(te)點：在真空、負壓、零壓時能正常工作，但通徑一般(ban)不超過25mm。
2）分步直動式電磁閥：
ATOS電磁(ci)閥(fa)(fa)原理：它(ta)是(shi)一種(zhong)直(zhi)動(dong)(dong)(dong)和先(xian)導(dao)式相結合的原理，當入口(kou)與(yu)出口(kou)沒有壓(ya)(ya)(ya)差時(shi)，通(tong)電后，電磁(ci)力(li)直(zhi)接把(ba)先(xian)導(dao)小(xiao)(xiao)閥(fa)(fa)和主(zhu)閥(fa)(fa)關閉件依次向上(shang)提起，閥(fa)(fa)門打開。當入口(kou)與(yu)出口(kou)達到啟(qi)動(dong)(dong)(dong)壓(ya)(ya)(ya)差時(shi)，通(tong)電后，電磁(ci)力(li)先(xian)導(dao)小(xiao)(xiao)閥(fa)(fa)，主(zhu)閥(fa)(fa)下(xia)(xia)腔壓(ya)(ya)(ya)力(li)上(shang)升，上(shang)腔壓(ya)(ya)(ya)力(li)下(xia)(xia)降(jiang)，從而利(li)用(yong)壓(ya)(ya)(ya)差把(ba)主(zhu)閥(fa)(fa)向上(shang)推開；斷電時(shi)，先(xian)導(dao)閥(fa)(fa)利(li)用(yong)彈簧力(li)或介質壓(ya)(ya)(ya)力(li)推動(dong)(dong)(dong)關閉件，向下(xia)(xia)移動(dong)(dong)(dong)，使閥(fa)(fa)門關閉。
ATOS電磁閥(fa)特點：在零(ling)壓差或(huo)真(zhen)空、高壓時亦能可(ke)*動作，但功率(lv)較大，要求必須水平(ping)安裝(zhuang)。
3）先導式電磁閥：
ATOS電(dian)磁閥原理：通(tong)電(dian)時，電(dian)磁力把先導(dao)孔打(da)開(kai)，上(shang)(shang)腔室壓(ya)力迅速(su)下(xia)降，在(zai)關(guan)(guan) 閉(bi)件周圍形成(cheng)上(shang)(shang)低下(xia)高的壓(ya)差(cha)，流體(ti)(ti)壓(ya)力推動關(guan)(guan)閉(bi)件向(xiang)上(shang)(shang)移動，閥門打(da)開(kai)；斷電(dian)時，彈(dan)簧力把先導(dao)孔關(guan)(guan)閉(bi)，入(ru)口(kou)壓(ya)力通(tong)過旁通(tong)孔迅速(su)腔室在(zai)關(guan)(guan)閥件周圍形成(cheng)下(xia)低上(shang)(shang)高的壓(ya)差(cha)，流體(ti)(ti)壓(ya)力推動關(guan)(guan)閉(bi)件向(xiang)下(xia)移動，關(guan)(guan)閉(bi)閥門。
ATOS電磁閥特點：流體(ti)壓力范圍上限較高，可任意安裝(zhuang)（需定制）但(dan)必須滿足(zu)流體(ti)壓差條件。
2、ATOS電磁閥從閥結構(gou)(gou)(gou)和材(cai)料上(shang)的不同(tong)與原理上(shang)的區別，分(fen)為(wei)六個分(fen)支(zhi)小(xiao)類：直(zhi)(zhi)動膜片結構(gou)(gou)(gou)、分(fen)步(bu)直(zhi)(zhi)動膜片結構(gou)(gou)(gou)、先(xian)導膜片結構(gou)(gou)(gou)、直(zhi)(zhi)動活(huo)塞結構(gou)(gou)(gou)、分(fen)步(bu)直(zhi)(zhi)動活(huo)塞結構(gou)(gou)(gou)、先(xian)導活(huo)塞結構(gou)(gou)(gou)。
3、ATOS電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)按(an)照功能分(fen)類(lei)：水用電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、制(zhi)冷電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、低溫(wen)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、燃氣(qi)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、消防電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、氨(an)用電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、氣(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、液體電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、微(wei)型電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、脈沖電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、液壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa) 常開電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、油用電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、防爆電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)等。
ATOS電磁閥(fa)選型注意：
ATOS電磁閥選型依(yi)據(ju)
ATOS電磁(ci)閥選型首(shou)先(xian)應該依次遵(zun)循安全性(xing)，可靠性(xing)，適用性(xing)，經(jing)濟性(xing)四大原 則，其(qi)次是根據六個方面的現場(chang)工(gong)況(kuang)（即(ji)管(guan)道參(can)數、流體參(can)數、壓力參(can)數、電氣參(can)數、動作方式、特殊要求進行選擇）。
ATOS電(dian)磁閥選型依據：
1、根據管道參數選(xuan)擇電(dian)磁(ci)閥的：通(tong)徑規格（即DN）、接口方(fang)式
1）按照現場管(guan)道內徑(jing)(jing)尺寸或流量要求(qiu)來確定通徑(jing)(jing)（DN）尺寸；
2）接口方式，一般>DN50要(yao)選擇(ze)法蘭接口，≤DN50則可根據用戶需要(yao)自由選擇(ze)。
2、根據流體(ti)參數(shu)選擇(ze)電(dian)磁閥的(de)：材質、溫度組
1）腐(fu)蝕性流(liu)(liu)體：宜選用耐腐(fu)蝕電磁(ci)閥(fa)和(he)全(quan)不(bu)銹鋼；食用超凈流(liu)(liu)體：宜選用食品級(ji)不(bu)銹鋼材質電磁(ci)閥(fa)；
2）高(gao)溫流體：要(yao)選擇(ze)采用耐高(gao)溫的(de)電工材料和密封材料制造的(de)電磁閥，而且要(yao)選擇(ze)活塞式結構(gou)類型的(de)；
3）流體狀態(tai)：大至有氣態(tai)，液(ye)態(tai)或混合狀態(tai)，特(te)別是口(kou)徑大于DN25時一定要區(qu)分開來；
4）流體粘度：通常在50cSt以(yi)下可任意選(xuan)擇，若超過此(ci)值，則要選(xuan)用高粘度電磁閥。
3、根據壓力參數選擇電磁(ci)閥的：原理和結(jie)構品種(zhong)
1）公(gong)稱壓力：這個參(can)數與(yu)其(qi)它通(tong)用閥門的含義是(shi)(shi)一樣的，是(shi)(shi)根據管道公(gong)稱壓力來定；
2）工作(zuo)壓(ya)力：如果工作(zuo)壓(ya)力低則(ze)必須選用直(zhi)動或分步直(zhi)動式原理；zui低工作(zuo)壓(ya)差(cha)在(zai)0.04Mpa以上時直(zhi)動式、分步直(zhi)動式、先導(dao)式均(jun)可選用。
4、電(dian)氣選擇：電(dian)壓規格應盡量優先選用(yong)AC220V、DC24較為方(fang)便(bian)。
5、根據(ju)持(chi)續(xu)工作(zuo)時間長(chang)短來選(xuan)擇：常(chang)閉、常(chang)開、或(huo)可持(chi)續(xu)通(tong)電
1）當電磁閥(fa)需要長時間開(kai)(kai)啟，并且持(chi)續(xu)的時間多于關閉的時間應選 用(yong)常開(kai)(kai)型；
2）要是開啟的(de)時(shi)(shi)間短或(huo)開和關的(de)時(shi)(shi)間不多時(shi)(shi)，則選常閉(bi)型；
3）但(dan)是有些用(yong)于(yu)安全保護的(de)工況(kuang)，如爐(lu)、窯火(huo)焰監測(ce)，則(ze)不能選常(chang)開的(de)，應選可長期通電型。
6、根據環境要求選擇(ze)輔助功能：防爆、止回、手動、防水(shui)(shui)霧、水(shui)(shui)淋、潛水(shui)(shui)。
