VICKERS電磁閥原理： VICKERS電磁(ci)閥(fa)(fa)和安(an)全(quan)閥(fa)(fa)為(wei)一體，組(zu)成先導式壓(ya)力閥(fa)(fa)，該(gai)閥(fa)(fa)即是(shi)(shi)卸(xie)(xie)(xie)荷(he)(he)閥(fa)(fa)又是(shi)(shi)安(an)全(quan)閥(fa)(fa)，有時(shi)(shi)又是(shi)(shi)溢(yi)流(liu)閥(fa)(fa)．卸(xie)(xie)(xie)荷(he)(he)時(shi)(shi)其(qi)控(kong)制(zhi)油(you)(you)(you)道(dao)(dao)貫(guan)(guan)穿各(ge)(ge)路換向(xiang)(xiang)(xiang)閥(fa)(fa)，同(tong)前述(shu)卸(xie)(xie)(xie)荷(he)(he)油(you)(you)(you)道(dao)(dao)．當各(ge)(ge)路換向(xiang)(xiang)(xiang)閥(fa)(fa)處(chu)于(yu)中立位置時(shi)(shi)，卸(xie)(xie)(xie)荷(he)(he)閥(fa)(fa)的(de)控(kong)制(zhi)油(you)(you)(you)道(dao)(dao)，貫(guan)(guan)穿各(ge)(ge)路換向(xiang)(xiang)(xiang)閥(fa)(fa)并與油(you)(you)(you)箱連(lian)通(tong)．卸(xie)(xie)(xie)荷(he)(he)時(shi)(shi)，大部分油(you)(you)(you)液卸(xie)(xie)(xie)荷(he)(he)，通(tong)道(dao)(dao)短，壓(ya)力損失低．任一路閥(fa)(fa)換向(xiang)(xiang)(xiang)工(gong)作，便切斷控(kong)制(zhi)油(you)(you)(you)道(dao)(dao)，油(you)(you)(you)源來油(you)(you)(you)就(jiu)從(cong)換向(xiang)(xiang)(xiang)閥(fa)(fa)進入(ru)執行元(yuan)件(jian)工(gong)作，其(qi)工(gong)作壓(ya)力大小由導閥(fa)(fa)控(kong)制(zhi)．此(ci)時(shi)(shi)系統壓(ya)力為(wei)導閥(fa)(fa)調整壓(ya)力．該(gai)種(zhong)卸(xie)(xie)(xie)荷(he)(he)方式，即使換向(xiang)(xiang)(xiang)閥(fa)(fa)路數(shu)增加，只是(shi)(shi)控(kong)制(zhi)油(you)(you)(you)道(dao)(dao)增加，卸(xie)(xie)(xie)荷(he)(he)壓(ya)力增加不大，始終保持(chi)較(jiao)低卸(xie)(xie)(xie)荷(he)(he)壓(ya)力，此(ci)種(zhong)卸(xie)(xie)(xie)荷(he)(he)方式多用于(yu)手動(dong)換向(xiang)(xiang)(xiang)閥(fa)(fa)，卸(xie)(xie)(xie)荷(he)(he)可(ke)靠 美國VICKERS電磁閥隔磁套管內(nei)的(de)鐵芯完成，不(bu)存在動(dong)密封，所以外(wai)漏(lou)易(yi)(yi)堵絕。電動(dong)閥力矩(ju)控制不(bu)易(yi)(yi)，容(rong)易(yi)(yi)產生內(nei)漏(lou)，甚至拉(la)斷閥桿頭(tou)部；電磁閥的(de)結構(gou)型式容(rong)易(yi)(yi)控制內(nei)泄漏(lou) ，直至降為零。 VICKERS電磁閥的(de)用(yong)途電(dian)(dian)磁閥(fa)(fa)(fa)用(yong)于(yu)液體和(he)氣(qi)體管(guan)路的(de)開(kai)(kai)關(guan)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)，是兩位DO控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)。一般(ban)(ban)(ban)用(yong)于(yu)小(xiao) 型管(guan)道的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)。電(dian)(dian)動(dong)(dong)閥(fa)(fa)(fa)用(yong)于(yu)液體、氣(qi)體和(he)風(feng)系統管(guan)道介質流量(liang)的(de)模擬量(liang)調(diao)節(jie)，是AI控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)。在(zai)大型閥(fa)(fa)(fa)門和(he)風(feng)系統的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)中也可以(yi)用(yong)電(dian)(dian)動(dong)(dong)閥(fa)(fa)(fa)做兩位開(kai)(kai)關(guan)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)。電(dian)(dian)磁閥(fa)(fa)(fa)只(zhi)能(neng)(neng)用(yong)作(zuo)(zuo)(zuo)開(kai)(kai)關(guan)量(liang)，是DO控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)，只(zhi)能(neng)(neng)用(yong)于(yu)小(xiao)管(guan)道控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)，常見于(yu)DN50及以(yi)下(xia)管(guan)道，往上就(jiu)很(hen)(hen)少了。電(dian)(dian)動(dong)(dong)閥(fa)(fa)(fa)可以(yi)有AI反饋信(xin)號，可以(yi)由DO或(huo)(huo)AO控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)，比(bi)較見于(yu)大管(guan)道和(he)風(feng)閥(fa)(fa)(fa)等(deng)。1.開(kai)(kai)關(guan)形式電(dian)(dian)磁閥(fa)(fa)(fa)通(tong)過線圈驅(qu)動(dong)(dong)，只(zhi)能(neng)(neng)開(kai)(kai)或(huo)(huo)關(guan)，開(kai)(kai)關(guan)時(shi)(shi)動(dong)(dong)作(zuo)(zuo)(zuo)時(shi)(shi)間(jian)短。電(dian)(dian)動(dong)(dong)閥(fa)(fa)(fa)的(de)驅(qu)動(dong)(dong)一般(ban)(ban)(ban)是用(yong)電(dian)(dian)機(ji)，開(kai)(kai)或(huo)(huo)關(guan)動(dong)(dong)作(zuo)(zuo)(zuo)完成需要(yao)一定的(de)時(shi)(shi)間(jian)模擬量(liang)的(de)，可以(yi)做調(diao)節(jie)。2.工(gong)作(zuo)(zuo)(zuo)性質電(dian)(dian)磁閥(fa)(fa)(fa)一般(ban)(ban)(ban)流通(tong)系數很(hen)(hen)小(xiao)，而且工(gong)作(zuo)(zuo)(zuo)壓(ya) 力差很(hen)(hen)小(xiao)。比(bi)如一般(ban)(ban)(ban)25口(kou)徑(jing)的(de)電(dian)(dian)磁閥(fa)(fa)(fa)流通(tong)系數比(bi)15口(kou)徑(jing)的(de)電(dian)(dian)動(dong)(dong)球閥(fa)(fa)(fa)小(xiao)很(hen)(hen)多。 VICKERS電(dian)磁閥的主要特(te)點(dian) (1)外(wai)漏堵絕，內(nei)漏易(yi)(yi)控(kong)，使(shi)(shi)用安全。內(nei)外(wai)泄漏是危(wei)及安全的要素。其它自控(kong)閥(fa)通常(chang)將(jiang)閥(fa)桿(gan)(gan)伸出，由電(dian)動(dong)(dong)、氣動(dong)(dong)、液動(dong)(dong)執行機構(gou)控(kong)制(zhi)(zhi)閥(fa)芯(xin)的轉動(dong)(dong)或(huo)移動(dong)(dong) 。這都要解決長期動(dong)(dong)作閥(fa)桿(gan)(gan)動(dong)(dong)密封的外(wai)泄漏難題；唯有(you)電(dian)磁閥(fa)是用電(dian)磁力(li)作用于(yu)密封在電(dian)動(dong)(dong)調(diao)節閥(fa)隔(ge)磁套管內(nei)的鐵芯(xin)完成(cheng)，不存(cun)在動(dong)(dong)密封，所以外(wai)漏易(yi)(yi)堵絕。電(dian)動(dong)(dong)閥(fa)力(li)矩控(kong)制(zhi)(zhi)不易(yi)(yi) ，容(rong)易(yi)(yi)產(chan)生內(nei)漏，甚(shen)至(zhi)拉斷閥(fa)桿(gan)(gan)頭部；電(dian)磁閥(fa)的結構(gou)型式容(rong)易(yi)(yi)控(kong)制(zhi)(zhi)內(nei)泄漏，直至(zhi)降為零。所以，電(dian)磁閥(fa)使(shi)(shi)用特別安全，尤其適用于(yu)腐(fu)蝕性、有(you)毒(du)或(huo)高低溫的介質。 (2)系統簡單， 便(bian)(bian)接電腦，價(jia)格(ge)低謙。電磁(ci)閥(fa)本身結(jie)構(gou)簡單，價(jia)格(ge)也低，比起調節閥(fa)等其(qi)它種(zhong)類(lei)執行器易于安裝(zhuang)維護(hu)。更顯著的是所組成的自控(kong)(kong)系統簡單得(de)多(duo)，價(jia)格(ge)要低得(de)多(duo)。由于電磁(ci)閥(fa)是開關 信號控(kong)(kong)制，與工控(kong)(kong)計算機連接十分方(fang)便(bian)(bian)。在(zai)當(dang)今電腦普及，價(jia)格(ge)大幅(fu)下降的時代，電磁(ci)閥(fa)的優勢就更加(jia)明顯。 (3)動作快遞，功率微小，外形輕巧。電(dian)磁閥(fa)(fa)(fa)(fa)響(xiang)應時間可(ke)以短至幾個 毫(hao)(hao)秒，即(ji)使是先(xian)導式(shi)電(dian)磁閥(fa)(fa)(fa)(fa)也可(ke)以控制在幾十毫(hao)(hao)秒內。由于自(zi)成回路，比之其它自(zi)控閥(fa)(fa)(fa)(fa)反應更靈敏。設計得當的電(dian)磁閥(fa)(fa)(fa)(fa)線圈(quan)功率消耗很低，屬節能產品；還可(ke)做(zuo)到只需觸發動作， 自(zi)動保持(chi)閥(fa)(fa)(fa)(fa)位，平時一點也不耗電(dian)。電(dian)磁閥(fa)(fa)(fa)(fa)外形尺寸(cun)小，既(ji)節省空間，又輕巧美(mei)觀(guan)。 (4)調節精度受限(xian)(xian)，適(shi)用介質受限(xian)(xian)。電磁閥(fa)通常只(zhi)(zhi)有開關兩種(zhong)狀(zhuang)(zhuang)態，閥(fa)芯只(zhi)(zhi)能(neng)處于兩個極限(xian)(xian)位置，不能(neng)連續調節，(力圖突破的(de)新構(gou)思不少，但還都處于試(shi)驗試(shi)用階段(duan))所(suo)以(yi)調節精度還受到一定(ding)限(xian)(xian)制。電磁閥(fa)對介質潔凈度有較(jiao)高要求，含顆粒(li)狀(zhuang)(zhuang)的(de)介質不能(neng)適(shi)用，如(ru)屬雜(za)質 須先濾(lv)去。另外，粘(zhan)稠狀(zhuang)(zhuang)介質不能(neng)適(shi)用，而且(qie)，特定(ding)的(de)產(chan)品適(shi)用的(de)介質粘(zhan)度范圍相對較(jiao)窄。 (5)型號多樣，用(yong)途(tu)廣泛(fan)。電磁閥雖有先天不足(zu)，優(you)點仍十分(fen)突出，所以就設計成多種(zhong)(zhong) 多樣的產品，滿足(zu)各種(zhong)(zhong)不同的需(xu)求(qiu)，用(yong)途(tu)極為(wei)廣泛(fan)。電磁閥技(ji)術的進步也(ye)都是圍繞著如(ru)何克服先天不足(zu)，如(ru)何更好地發揮固有優(you)勢(shi)而展開。 VICKERS電(dian)磁(ci)(ci)閥(fa)是用來控(kong)(kong)制(zhi)(zhi)流(liu)體方向(xiang)的(de)(de)(de)(de)(de)自動(dong)(dong) 化(hua)基礎元件(jian)，屬于(yu)執(zhi)行器；通(tong)(tong)常(chang)(chang)用于(yu)機械控(kong)(kong)制(zhi)(zhi)和工(gong)業閥(fa)門上(shang)面，對(dui)介質方向(xiang)進行控(kong)(kong)制(zhi)(zhi)，從而達到對(dui)閥(fa)門開關的(de)(de)(de)(de)(de)控(kong)(kong)制(zhi)(zhi)。工(gong)作(zuo)原理電(dian)磁(ci)(ci)閥(fa)里有密閉的(de)(de)(de)(de)(de)腔，在不同(tong)位(wei)置開有通(tong)(tong)孔(kong)，每個孔(kong) 都通(tong)(tong)向(xiang)不同(tong)的(de)(de)(de)(de)(de)油(you)管，腔中間是閥(fa)，兩(liang)面是兩(liang)塊電(dian)磁(ci)(ci)鐵，哪(na)面的(de)(de)(de)(de)(de)磁(ci)(ci)鐵線圈通(tong)(tong)電(dian)閥(fa)體就(jiu)會(hui)被吸引到哪(na)邊(bian)，通(tong)(tong)過(guo)(guo)控(kong)(kong)制(zhi)(zhi)閥(fa)體的(de)(de)(de)(de)(de)移動(dong)(dong)來擋住或漏出不同(tong)的(de)(de)(de)(de)(de)排(pai)油(you)的(de)(de)(de)(de)(de)孔(kong)，而進油(you)孔(kong)是常(chang)(chang)開的(de)(de)(de)(de)(de)，液壓 油(you)就(jiu)會(hui)進入不同(tong)的(de)(de)(de)(de)(de)排(pai)油(you)管，然(ran)后通(tong)(tong)過(guo)(guo)油(you)的(de)(de)(de)(de)(de)壓力(li)來推動(dong)(dong)油(you)缸的(de)(de)(de)(de)(de)活(huo)塞(sai)，活(huo)塞(sai)又帶動(dong)(dong)活(huo)塞(sai)桿，活(huo)塞(sai)桿帶動(dong)(dong)機械裝(zhuang)置動(dong)(dong)。這樣(yang)通(tong)(tong)過(guo)(guo)控(kong)(kong)制(zhi)(zhi)電(dian)磁(ci)(ci)鐵的(de)(de)(de)(de)(de)電(dian)流(liu)通(tong)(tong)斷就(jiu)控(kong)(kong)制(zhi)(zhi)了機械運動(dong)(dong)。
