力士樂電磁閥主要特點 1、外漏堵絕(jue),內漏易控,使用安全 內外泄漏(lou)(lou)是危(wei)及安全(quan)的(de)要素。其(qi)它(ta)自控(kong)閥(fa)通(tong)常將閥(fa)桿(gan)伸出,由電(dian)動(dong)、氣動(dong)、液動(dong)執行機(ji)構(gou)控(kong)制(zhi)閥(fa)芯的(de)轉動(dong)或移動(dong)。這都要解(jie)決(jue)長期動(dong)作(zuo)閥(fa)桿(gan)動(dong)密封(feng)的(de)外泄漏(lou)(lou)難題;唯有電(dian)磁(ci)(ci)閥(fa)是用電(dian)磁(ci)(ci)力作(zuo)用于(yu)密封(feng)在(zai)電(dian)動(dong)調節(jie)閥(fa)隔磁(ci)(ci)套(tao)管內的(de)鐵芯完成(cheng),不存在(zai)動(dong)密封(feng),所以外漏(lou)(lou)易堵絕。電(dian)動(dong)閥(fa)力矩控(kong)制(zhi)不易,容(rong)易產生(sheng)內漏(lou)(lou),甚(shen)至拉(la)斷閥(fa)桿(gan)頭部;電(dian)磁(ci)(ci)閥(fa)的(de)結構(gou)型式容(rong)易控(kong)制(zhi)內泄漏(lou)(lou),直至降為零。所以,電(dian)磁(ci)(ci)閥(fa)使用特別安全(quan),尤其(qi)適(shi)用于(yu)腐蝕性、有毒或高低溫(wen)的(de)介質。 2、系統簡單,便接電腦,價格低廉 電磁閥本身結構簡(jian)單,價格也低,比起調節(jie)閥等其(qi)它種類執行器易于安裝維(wei)護(hu)。更顯(xian)著的是所(suo)組成的自控(kong)系(xi)統簡(jian)單得(de)多(duo),價格要低得(de)多(duo)。由(you)于電磁閥是開關信號控(kong)制,與工控(kong)計算機連接十分方便。在當今電腦普(pu)及,價格大幅下(xia)降的時代,電磁閥的優勢(shi)就更加明顯(xian)。 3、動(dong)作快遞,功率微小,外形輕(qing)巧(qiao) 電(dian)磁(ci)閥響應時間可以短至幾個(ge)毫秒(miao)(miao),即使(shi)是(shi)先導式電(dian)磁(ci)閥也可以控(kong)(kong)制(zhi)在幾十毫秒(miao)(miao)內。由(you)于自(zi)成回路,比之其它自(zi)控(kong)(kong)閥反應更靈(ling)敏。設(she)計(ji)得當的電(dian)磁(ci)閥線圈(quan)功率消耗很低,屬節能(neng)產品;還可做到只需(xu)觸發動作,自(zi)動保持(chi)閥位(wei),平時一(yi)點也不(bu)耗電(dian)。電(dian)磁(ci)閥外(wai)形尺寸小,既節省空間,又輕巧美(mei)觀。 4、調節精度(du)受(shou)(shou)限,適用介質受(shou)(shou)限 電磁閥(fa)(fa)通常只有(you)開關兩種狀態,閥(fa)(fa)芯(xin)只能(neng)處于兩個極(ji)限(xian)位置,不能(neng)連續(xu)調(diao)節,所以(yi)調(diao)節精(jing)度還受到一定(ding)限(xian)制(zhi)。 電磁閥對介質(zhi)(zhi)(zhi)潔(jie)凈度有較高要求,含顆粒狀的介質(zhi)(zhi)(zhi)不能適用,如屬雜(za)質(zhi)(zhi)(zhi)須(xu)先濾去。另外(wai),粘稠(chou)狀介質(zhi)(zhi)(zhi)不能適用,而且,特(te)定的產(chan)品適用的介質(zhi)(zhi)(zhi)粘度范圍相(xiang)對較窄。 5、型號(hao)多樣(yang),用途廣泛(fan) 電磁(ci)(ci)閥(fa)雖(sui)有(you)先(xian)天不足(zu),優點仍(reng)十分(fen)突出,所以就(jiu)設計成多(duo)種多(duo)樣的(de)產品,滿足(zu)各種不同的(de)需求,用(yong)途極為廣泛(fan)。電磁(ci)(ci)閥(fa)技術的(de)進步也(ye)都是圍(wei)繞著如何(he)克服先(xian)天不足(zu),如何(he)更好地發揮(hui)固有(you)優勢而展開。 1、電磁閥從原理上分(fen)為三大(da)類(lei): 直動式電(dian)磁(ci)閥 原(yuan)理:通電時(shi),電磁線圈產生電磁力(li)把關閉件(jian)從閥(fa)座上提起,閥(fa)門(men)打(da)開;斷電時(shi),電磁力(li)消失,彈簧(huang)把關閉件(jian)壓在閥(fa)座上,閥(fa)門(men)關閉。 特點:在真空、負壓、零壓時能正常工作,但通徑(jing)一般(ban)不超(chao)過25mm。 分步直動(dong)式電磁閥 原(yuan)理:它是(shi)一種直(zhi)動(dong)和先(xian)導(dao)式相結合的原(yuan)理,當入口(kou)與(yu)出口(kou)沒有壓(ya)(ya)差(cha)時,通(tong)電(dian)后,電(dian)磁(ci)力(li)(li)直(zhi)接把先(xian)導(dao)小閥(fa)(fa)(fa)(fa)和主閥(fa)(fa)(fa)(fa)關閉(bi)件依次向上(shang)(shang)提起,閥(fa)(fa)(fa)(fa)門打開。當入口(kou)與(yu)出口(kou)達(da)到(dao)啟動(dong)壓(ya)(ya)差(cha)時,通(tong)電(dian)后,電(dian)磁(ci)力(li)(li)先(xian)導(dao)小閥(fa)(fa)(fa)(fa),主閥(fa)(fa)(fa)(fa)下腔(qiang)壓(ya)(ya)力(li)(li)上(shang)(shang)升,上(shang)(shang)腔(qiang)壓(ya)(ya)力(li)(li)下降,從(cong)而利用壓(ya)(ya)差(cha)把主閥(fa)(fa)(fa)(fa)向上(shang)(shang)推(tui)開;斷電(dian)時,先(xian)導(dao)閥(fa)(fa)(fa)(fa)利用彈簧(huang)力(li)(li)或介質壓(ya)(ya)力(li)(li)推(tui)動(dong)關閉(bi)件,向下移動(dong),使閥(fa)(fa)(fa)(fa)門關閉(bi)。 特(te)點:在(zai)零(ling)壓(ya)差(cha)或真空、高壓(ya)時亦(yi)能可*動作,但功率(lv)較大,要求必須水平(ping)安(an)裝(zhuang)。 先導式(shi)電磁閥 原理:通(tong)(tong)電時,電磁力(li)把先(xian)導孔(kong)打開(kai),上(shang)腔室(shi)壓(ya)(ya)(ya)力(li)迅速下(xia)降(jiang),在關(guan) 閉件(jian)(jian)(jian)周圍(wei)形成上(shang)低下(xia)高(gao)的(de)壓(ya)(ya)(ya)差,流體壓(ya)(ya)(ya)力(li)推動(dong)關(guan)閉件(jian)(jian)(jian)向(xiang)上(shang)移(yi)動(dong),閥(fa)門(men)打開(kai);斷(duan)電時,彈簧(huang)力(li)把先(xian)導孔(kong)關(guan)閉,入口壓(ya)(ya)(ya)力(li)通(tong)(tong)過(guo)旁通(tong)(tong)孔(kong)迅速腔室(shi)在關(guan)閥(fa)件(jian)(jian)(jian)周圍(wei)形成下(xia)低上(shang)高(gao)的(de)壓(ya)(ya)(ya)差,流體壓(ya)(ya)(ya)力(li)推動(dong)關(guan)閉件(jian)(jian)(jian)向(xiang)下(xia)移(yi)動(dong),關(guan)閉閥(fa)門(men)。 特(te)點:流體壓力(li)范圍上限較高,可任意安裝(需定制)但必須(xu)滿足流體壓差條(tiao)件。 2、電磁閥從閥結構(gou)和材料上的不(bu)同與原理(li)上的區別,分(fen)(fen)為六個分(fen)(fen)支小類:直(zhi)動膜片(pian)結構(gou)、分(fen)(fen)步(bu)直(zhi)動膜片(pian)結構(gou)、先(xian)導膜片(pian)結構(gou)、直(zhi)動活塞(sai)結構(gou)、分(fen)(fen)步(bu)直(zhi)動活塞(sai)結構(gou)、先(xian)導活塞(sai)結構(gou)。 3、電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)按照功(gong)能(neng)分類(lei):水用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、制(zhi)冷(leng)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、低(di)溫(wen)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、燃氣電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、消(xiao)防(fang)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、氨用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、氣體(ti)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、液(ye)(ye)體(ti)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、微型電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、脈沖電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、液(ye)(ye)壓電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)
