意大利ATOS電磁換向閥的特點: (1)外漏(lou)堵絕(jue),內(nei)(nei)漏(lou)易(yi)(yi)(yi)控(kong)(kong)(kong),使(shi)用(yong)(yong)安(an)全(quan)。內(nei)(nei)外泄漏(lou)是危及安(an)全(quan)的(de)(de)要(yao)素。其它(ta)自控(kong)(kong)(kong)閥(fa)通常將閥(fa)桿(gan)伸出,由(you)電(dian)(dian)動(dong)(dong)(dong)、氣動(dong)(dong)(dong)、液動(dong)(dong)(dong)執行機構控(kong)(kong)(kong)制(zhi)閥(fa)芯(xin)的(de)(de)轉動(dong)(dong)(dong)或(huo)(huo)移動(dong)(dong)(dong)。這都(dou)要(yao)解決長期動(dong)(dong)(dong)作(zuo)閥(fa)桿(gan)動(dong)(dong)(dong)密封(feng)的(de)(de)外泄漏(lou)難題;唯有電(dian)(dian)磁(ci)(ci)閥(fa)是用(yong)(yong)電(dian)(dian)磁(ci)(ci)力作(zuo)用(yong)(yong)于(yu)密封(feng)在(zai)電(dian)(dian)動(dong)(dong)(dong)調(diao)節閥(fa)隔(ge)磁(ci)(ci)套管內(nei)(nei)的(de)(de)鐵芯(xin)完成,不(bu)存在(zai)動(dong)(dong)(dong)密封(feng),所以(yi)外漏(lou)易(yi)(yi)(yi)堵絕(jue)。電(dian)(dian)動(dong)(dong)(dong)閥(fa)力矩控(kong)(kong)(kong)制(zhi)不(bu)易(yi)(yi)(yi),容易(yi)(yi)(yi)產生(sheng)內(nei)(nei)漏(lou),甚至(zhi)拉斷閥(fa)桿(gan)頭部;電(dian)(dian)磁(ci)(ci)閥(fa)的(de)(de)結構型式(shi)容易(yi)(yi)(yi)控(kong)(kong)(kong)制(zhi)內(nei)(nei)泄漏(lou),直至(zhi)降(jiang)為(wei)零。所以(yi),電(dian)(dian)磁(ci)(ci)閥(fa)使(shi)用(yong)(yong)特別(bie)安(an)全(quan),尤其適用(yong)(yong)于(yu)腐蝕性、有毒(du)或(huo)(huo)高低溫的(de)(de)介(jie)質。 (2)系統簡(jian)單,便接(jie)電(dian)腦,價(jia)(jia)(jia)格(ge)低謙(qian)。電(dian)磁(ci)閥(fa)本身結(jie)構簡(jian)單,價(jia)(jia)(jia)格(ge)也低,比(bi)起調節(jie)閥(fa)等其它(ta)種(zhong)類執行器(qi)易于(yu)安(an)裝維護。更(geng)(geng)顯(xian)著的(de)是(shi)所(suo)組成(cheng)的(de)自控系統簡(jian)單得多(duo),價(jia)(jia)(jia)格(ge)要低得多(duo)。由(you)于(yu)電(dian)磁(ci)閥(fa)是(shi)開關信號控制,與工控計算機連接(jie)十分方便。在當(dang)今電(dian)腦普及(ji),價(jia)(jia)(jia)格(ge)大幅(fu)下降的(de)時代,電(dian)磁(ci)閥(fa)的(de)優勢就更(geng)(geng)加明顯(xian)。 (3)動(dong)作快遞,功率微小,外形輕巧。電磁閥(fa)(fa)(fa)響應(ying)時(shi)間(jian)可以短至幾個毫(hao)(hao)秒,即(ji)使是先導式電磁閥(fa)(fa)(fa)也可以控制在幾十(shi)毫(hao)(hao)秒內。由于自(zi)成回路,比之其它自(zi)控閥(fa)(fa)(fa)反應(ying)更靈(ling)敏。設計得當的電磁閥(fa)(fa)(fa)線圈功率消耗很低(di),屬(shu)節(jie)能產品(pin);還(huan)可做到只(zhi)需觸(chu)發(fa)動(dong)作,自(zi)動(dong)保持閥(fa)(fa)(fa)位,平時(shi)一點也不耗電。電磁閥(fa)(fa)(fa)外形尺(chi)寸小,既節(jie)省(sheng)空間(jian),又輕巧美觀(guan)。 (4)調節(jie)精(jing)度受(shou)限(xian)(xian),適(shi)用介質(zhi)受(shou)限(xian)(xian)。電磁(ci)閥通(tong)常只(zhi)(zhi)有開關兩(liang)種狀(zhuang)(zhuang)態,閥芯只(zhi)(zhi)能處于(yu)兩(liang)個(ge)極(ji)限(xian)(xian)位置,不能連續調節(jie),(力圖突破的(de)新構思不少,但還都(dou)處于(yu)試(shi)驗試(shi)用階段)所以調節(jie)精(jing)度還受(shou)到一定限(xian)(xian)制。電磁(ci)閥對介質(zhi)潔凈度有較(jiao)高要(yao)求(qiu),含顆粒狀(zhuang)(zhuang)的(de)介質(zhi)不能適(shi)用,如屬雜質(zhi)須(xu)先濾去。另外,粘(zhan)稠狀(zhuang)(zhuang)介質(zhi)不能適(shi)用,而且,特(te)定的(de)產品適(shi)用的(de)介質(zhi)粘(zhan)度范圍相對較(jiao)窄。 (5)型號多(duo)樣,用途廣(guang)泛(fan)。電磁(ci)閥雖有先(xian)天(tian)(tian)不(bu)足,優點仍十分突(tu)出,所以就設計成多(duo)種(zhong)多(duo)樣的(de)產(chan)品,滿足各種(zhong)不(bu)同的(de)需求,用途極為廣(guang)泛(fan)。電磁(ci)閥技術(shu)的(de)進步(bu)也都是圍(wei)繞著(zhu)如何克服先(xian)天(tian)(tian)不(bu)足,如何更好地(di)發揮(hui)固有優勢而展(zhan)開。 意大利ATOS電磁閥DHI系列型號: DHI-0610/A-X 230/50/60AC DHI-0610/A-X 24DC 23 DHI-0610-X 110/50/60AC DHI-0610-X 230/50/60AC 23 DHI-0610-X 24DC DHI-0611/A-X 24DC 23 DHI-0611/FC-X 24DC 23 DHI-06119/A-X 24DC 23 DHI-0611-X 24DC 23 DHI-0612/A-X 24DC DHI-0613/A-X 24DC 23 DHI-0613/WP-X 230AC DHI-0613-X 230/50/60AC DHI-0613-X 24DC DHI-0614-X 24DC DHI-0616/A-X 230/50/60AC DHI-0618/A-X 24DC 23 DHI-0630/2/A-X 230/50/60AC 23 DHI-0630/2/A-X 24DC 23 DHI-0630/2-X 24DC DHI-0631/1/2/A-X 24DC DHI-0631/2/A-IX 24DC DHI-0631/2/A-X 110/50/60AC 23 DHI-0631/2/A-X 230/50/60AC 23 DHI-0631/2/P-X 24DC DHI-0631/2/WP-X 12DC 23 DHI-0631/2/WP-X 220DC 23 DHI-0631/2/WP-X 230/50/60AC DHI-0631/2P/A-X 24DC DHI-0631/2P-X 24DC DHI-0631/2-X 230/50/60AC DHI-0631/2-X 110/50/60AC DHI-0631/2-X 220DC DHI-0631/2-X 230/50/60AC DHI-0631/2-X 24DC DHI-0632/2/A-X 230/50/60AC 23 DHI-0632/2/A-X 24DC 23 DHI-0632/2-X 230/50/60AC DHI-0632/2-X 24DC 23 DHI-0639/C-X 24DC 23 DHI-0670-X 24DC 23 DHI-0671/A-X 24DC DHI-0671/FC-X 24DC 23 DHI-0674-X 24DC 23 DHI-0701/2-X 110/50/60AC DHI-0710/WP-X 24DC 23 DHI-0710-X 230/50/60AC DHI-0710-X 24DC DHI-0711-X 24DC DHI-0711-X 110/50/60AC 23 DHI-0711-X 230/50/60AC DHI-0713/1-X 230/50/60AC DHI-0713/WP-X 12DC 23 DHI-0713/WP-X 230/50/60AC 23 DHI-0713/WP-X 24DC 23 DHI-07139-X 24DC 23 DHI-0713P 24DC DHI-0713-X 110/50/60AC DHI-0713-X 230/50/60AC DHI-0713-X 24DC DHI-0713-X 24DC 23 /PE DHI-0714/WP-X 230/50/60AC DHI-0714/WP-X 230/50/60AC 23 /PE DHI-0714-X 230/50/60AC DHI-0714-X 24DC DHI-0715/FI/NC-X 24DC DHI-0715-X 24DC DHI-0716-X 24DC DHI-0717-X 24DC DHI-0718-X 230/50/60AC DHI-0718-X 24DC DHI-0750/2-X 24DC DHI-0751/2/FI/NC-X 24DC 23 DHI-0751/2/FI/NO-X 24DC 23 DHI-0751/2/WP-X 230/50/60AC DHI-0751/2/WP-X 230/50/60AC 23 /PE DHI-0751/2/WP-X 24DC DHI-0751/2-X 110/50/60AC 23 DHI-0751/2-X 230/50/60AC DHI-0751/2-X 24DC |
