力士樂電磁閥主要特點 1、外(wai)漏(lou)堵(du)絕,內漏(lou)易控,使用安全(quan) 內(nei)(nei)(nei)外(wai)泄(xie)漏(lou)是危(wei)及安(an)全的(de)要(yao)素(su)。其它自控(kong)閥(fa)通常將閥(fa)桿(gan)伸出,由電(dian)(dian)動(dong)、氣動(dong)、液動(dong)執行機構控(kong)制(zhi)閥(fa)芯的(de)轉動(dong)或移動(dong)。這都要(yao)解(jie)決長期(qi)動(dong)作閥(fa)桿(gan)動(dong)密封(feng)的(de)外(wai)泄(xie)漏(lou)難題(ti);唯有(you)電(dian)(dian)磁(ci)閥(fa)是用電(dian)(dian)磁(ci)力作用于(yu)密封(feng)在電(dian)(dian)動(dong)調節閥(fa)隔磁(ci)套(tao)管(guan)內(nei)(nei)(nei)的(de)鐵芯完成,不存在動(dong)密封(feng),所以(yi)外(wai)漏(lou)易堵絕。電(dian)(dian)動(dong)閥(fa)力矩控(kong)制(zhi)不易,容(rong)易產生內(nei)(nei)(nei)漏(lou),甚至拉斷閥(fa)桿(gan)頭部;電(dian)(dian)磁(ci)閥(fa)的(de)結構型式容(rong)易控(kong)制(zhi)內(nei)(nei)(nei)泄(xie)漏(lou),直(zhi)至降為零(ling)。所以(yi),電(dian)(dian)磁(ci)閥(fa)使(shi)用特別安(an)全,尤其適用于(yu)腐蝕性、有(you)毒或高低溫的(de)介(jie)質。 2、系統簡單,便接電(dian)腦,價格低廉(lian) 電磁閥(fa)本身(shen)結構簡單(dan),價(jia)格(ge)也低,比起(qi)調節閥(fa)等其它種類執行器易于安裝維護(hu)。更(geng)顯著的(de)(de)是所(suo)組成的(de)(de)自控(kong)系統簡單(dan)得多,價(jia)格(ge)要低得多。由于電磁閥(fa)是開關信號控(kong)制,與工控(kong)計算機連接十分方便(bian)。在當今電腦(nao)普及(ji),價(jia)格(ge)大幅下降的(de)(de)時代(dai),電磁閥(fa)的(de)(de)優勢就更(geng)加(jia)明顯。 3、動(dong)作快遞(di),功率微小,外形(xing)輕巧 電磁(ci)閥(fa)響應時(shi)間可以短至幾個毫秒(miao),即使是先導式電磁(ci)閥(fa)也可以控(kong)(kong)制在幾十(shi)毫秒(miao)內。由于自成回路,比之其它自控(kong)(kong)閥(fa)反(fan)應更靈敏(min)。設(she)計得當的電磁(ci)閥(fa)線圈(quan)功(gong)率消耗很低,屬節能產品;還(huan)可做到(dao)只需觸(chu)發動(dong)作,自動(dong)保持閥(fa)位,平(ping)時(shi)一點也不耗電。電磁(ci)閥(fa)外(wai)形尺寸小,既節省空(kong)間,又輕巧美觀。 4、調節精度(du)受(shou)限,適用介(jie)質(zhi)受(shou)限 電(dian)磁閥(fa)通常只(zhi)有開關兩種狀態(tai),閥(fa)芯只(zhi)能(neng)處于兩個極限位(wei)置,不能(neng)連續調(diao)節,所以調(diao)節精度(du)還(huan)受到一定限制。 電磁閥對介質潔(jie)凈(jing)度有(you)較高要求,含(han)顆粒狀的介質不能適用(yong),如屬雜(za)質須先濾去。另外,粘(zhan)稠(chou)狀介質不能適用(yong),而且,特定的產品適用(yong)的介質粘(zhan)度范圍相對較窄。 5、型號多樣,用(yong)途(tu)廣泛 電磁閥雖有先天不(bu)足,優點(dian)仍(reng)十分(fen)突出,所以就設(she)計(ji)成(cheng)多(duo)種(zhong)多(duo)樣的產品(pin),滿足各(ge)種(zhong)不(bu)同的需求(qiu),用途(tu)極為廣泛。電磁閥技(ji)術(shu)的進步也都是(shi)圍繞(rao)著如(ru)何克服先天不(bu)足,如(ru)何更好地(di)發揮固有優勢(shi)而(er)展(zhan)開。 1、電(dian)磁閥從原理上(shang)分為三大類: 直動式電磁閥(fa) 原理:通電(dian)(dian)時,電(dian)(dian)磁(ci)(ci)(ci)線圈產生電(dian)(dian)磁(ci)(ci)(ci)力把關閉件從閥座上提起,閥門(men)打開(kai);斷電(dian)(dian)時,電(dian)(dian)磁(ci)(ci)(ci)力消失,彈簧(huang)把關閉件壓在閥座上,閥門(men)關閉。 特點:在(zai)真空、負壓、零壓時(shi)能正常工作,但(dan)通徑一般(ban)不超過25mm。 分(fen)步直動式電(dian)磁閥(fa) 原(yuan)理:它是一(yi)種(zhong)直動和先導(dao)式(shi)相(xiang)結合的原(yuan)理,當入(ru)口與(yu)出口沒有壓(ya)(ya)差(cha)時(shi),通(tong)電(dian)后,電(dian)磁(ci)力(li)直接把先導(dao)小閥(fa)和主(zhu)閥(fa)關(guan)閉(bi)件依次向(xiang)上提起,閥(fa)門(men)打開。當入(ru)口與(yu)出口達到啟動壓(ya)(ya)差(cha)時(shi),通(tong)電(dian)后,電(dian)磁(ci)力(li)先導(dao)小閥(fa),主(zhu)閥(fa)下(xia)腔壓(ya)(ya)力(li)上升,上腔壓(ya)(ya)力(li)下(xia)降,從而利(li)用壓(ya)(ya)差(cha)把主(zhu)閥(fa)向(xiang)上推開;斷電(dian)時(shi),先導(dao)閥(fa)利(li)用彈簧力(li)或介(jie)質壓(ya)(ya)力(li)推動關(guan)閉(bi)件,向(xiang)下(xia)移(yi)動,使閥(fa)門(men)關(guan)閉(bi)。 特點:在(zai)零壓差或真空、高壓時亦(yi)能可*動作,但功率較(jiao)大,要求必須水平安(an)裝。 先(xian)導(dao)式電磁閥 原理:通電時,電磁力(li)(li)把(ba)先(xian)導孔打(da)開,上(shang)(shang)腔室(shi)壓(ya)(ya)力(li)(li)迅速下(xia)降,在(zai)關(guan)(guan)(guan) 閉(bi)件(jian)周圍形(xing)成(cheng)上(shang)(shang)低下(xia)高的(de)壓(ya)(ya)差,流(liu)體壓(ya)(ya)力(li)(li)推動關(guan)(guan)(guan)閉(bi)件(jian)向(xiang)上(shang)(shang)移(yi)動,閥(fa)(fa)門打(da)開;斷電時,彈簧力(li)(li)把(ba)先(xian)導孔關(guan)(guan)(guan)閉(bi),入(ru)口(kou)壓(ya)(ya)力(li)(li)通過(guo)旁通孔迅速腔室(shi)在(zai)關(guan)(guan)(guan)閥(fa)(fa)件(jian)周圍形(xing)成(cheng)下(xia)低上(shang)(shang)高的(de)壓(ya)(ya)差,流(liu)體壓(ya)(ya)力(li)(li)推動關(guan)(guan)(guan)閉(bi)件(jian)向(xiang)下(xia)移(yi)動,關(guan)(guan)(guan)閉(bi)閥(fa)(fa)門。 特點:流(liu)體壓(ya)力范圍上限較高(gao),可任意安裝(需(xu)定制)但(dan)必須滿足流(liu)體壓(ya)差條件。 2、電磁閥(fa)從閥(fa)結(jie)(jie)構(gou)和材料(liao)上的(de)不同與(yu)原理(li)上的(de)區別,分(fen)為六個分(fen)支小類(lei):直動(dong)膜(mo)片(pian)(pian)結(jie)(jie)構(gou)、分(fen)步(bu)(bu)直動(dong)膜(mo)片(pian)(pian)結(jie)(jie)構(gou)、先(xian)(xian)導(dao)膜(mo)片(pian)(pian)結(jie)(jie)構(gou)、直動(dong)活(huo)塞(sai)結(jie)(jie)構(gou)、分(fen)步(bu)(bu)直動(dong)活(huo)塞(sai)結(jie)(jie)構(gou)、先(xian)(xian)導(dao)活(huo)塞(sai)結(jie)(jie)構(gou)。 3、電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)按照功能分(fen)類(lei):水用電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、制冷電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、低(di)溫(wen)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、燃氣(qi)(qi)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、消防電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、氨用電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、液體(ti)(ti)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、微型電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、脈沖電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、液壓電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa) 常開(kai)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、油(you)用電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、直(zhi)流(liu)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、高壓電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、防爆(bao)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)等。
