意大利ATOS電磁換向閥的特點: (1)外(wai)漏(lou)堵絕,內漏(lou)易(yi)控,使用(yong)安全(quan)。內外(wai)泄(xie)漏(lou)是危及(ji)安全(quan)的(de)要素。其(qi)它(ta)自控閥(fa)(fa)通常將閥(fa)(fa)桿(gan)(gan)伸出,由(you)電(dian)(dian)動(dong)、氣動(dong)、液動(dong)執行機(ji)構(gou)控制(zhi)(zhi)閥(fa)(fa)芯(xin)(xin)的(de)轉動(dong)或(huo)移動(dong)。這都(dou)要解決長期(qi)動(dong)作(zuo)閥(fa)(fa)桿(gan)(gan)動(dong)密(mi)封(feng)的(de)外(wai)泄(xie)漏(lou)難題;唯有(you)電(dian)(dian)磁(ci)(ci)閥(fa)(fa)是用(yong)電(dian)(dian)磁(ci)(ci)力作(zuo)用(yong)于密(mi)封(feng)在電(dian)(dian)動(dong)調節閥(fa)(fa)隔磁(ci)(ci)套管(guan)內的(de)鐵芯(xin)(xin)完成,不(bu)(bu)存在動(dong)密(mi)封(feng),所以外(wai)漏(lou)易(yi)堵絕。電(dian)(dian)動(dong)閥(fa)(fa)力矩控制(zhi)(zhi)不(bu)(bu)易(yi),容易(yi)產生內漏(lou),甚至(zhi)拉斷(duan)閥(fa)(fa)桿(gan)(gan)頭部;電(dian)(dian)磁(ci)(ci)閥(fa)(fa)的(de)結(jie)構(gou)型式容易(yi)控制(zhi)(zhi)內泄(xie)漏(lou),直至(zhi)降(jiang)為(wei)零。所以,電(dian)(dian)磁(ci)(ci)閥(fa)(fa)使用(yong)特別安全(quan),尤其(qi)適用(yong)于腐(fu)蝕性、有(you)毒或(huo)高低溫的(de)介質。 (2)系統簡(jian)單(dan),便接電(dian)腦,價(jia)格低(di)(di)謙。電(dian)磁閥本身結(jie)構簡(jian)單(dan),價(jia)格也低(di)(di),比(bi)起調節閥等其它(ta)種類執行器(qi)易于(yu)安裝(zhuang)維護。更顯著的(de)是所組(zu)成的(de)自控系統簡(jian)單(dan)得多(duo)(duo),價(jia)格要低(di)(di)得多(duo)(duo)。由于(yu)電(dian)磁閥是開關信號控制(zhi),與工控計算機(ji)連接十分方便。在當今電(dian)腦普及(ji),價(jia)格大幅下降的(de)時代,電(dian)磁閥的(de)優勢就更加明顯。 (3)動(dong)(dong)(dong)作快遞(di),功(gong)率(lv)微小(xiao),外(wai)(wai)形輕(qing)巧。電(dian)(dian)磁閥(fa)響應(ying)時(shi)間可(ke)(ke)以(yi)短至幾(ji)個毫秒,即使是先導(dao)式電(dian)(dian)磁閥(fa)也可(ke)(ke)以(yi)控(kong)制在幾(ji)十毫秒內。由于自(zi)(zi)成回路(lu),比之其(qi)它自(zi)(zi)控(kong)閥(fa)反應(ying)更靈(ling)敏。設計得當的電(dian)(dian)磁閥(fa)線圈功(gong)率(lv)消耗很(hen)低,屬(shu)節能產(chan)品;還可(ke)(ke)做到(dao)只需觸發動(dong)(dong)(dong)作,自(zi)(zi)動(dong)(dong)(dong)保持閥(fa)位,平(ping)時(shi)一點也不耗電(dian)(dian)。電(dian)(dian)磁閥(fa)外(wai)(wai)形尺寸小(xiao),既節省空間,又(you)輕(qing)巧美觀。 (4)調(diao)節精度(du)受限(xian),適用(yong)介質(zhi)(zhi)受限(xian)。電磁閥(fa)(fa)通常只有(you)(you)開關兩(liang)種狀(zhuang)態,閥(fa)(fa)芯只能處于兩(liang)個(ge)極限(xian)位置(zhi),不(bu)能連續調(diao)節,(力圖(tu)突破的新構(gou)思不(bu)少,但還都處于試(shi)驗(yan)試(shi)用(yong)階段)所以調(diao)節精度(du)還受到(dao)一定(ding)限(xian)制。電磁閥(fa)(fa)對介質(zhi)(zhi)潔凈(jing)度(du)有(you)(you)較(jiao)高要求,含(han)顆粒狀(zhuang)的介質(zhi)(zhi)不(bu)能適用(yong),如屬雜質(zhi)(zhi)須(xu)先濾(lv)去(qu)。另外,粘稠狀(zhuang)介質(zhi)(zhi)不(bu)能適用(yong),而且,特定(ding)的產品適用(yong)的介質(zhi)(zhi)粘度(du)范圍相對較(jiao)窄。 (5)型號多樣,用(yong)途(tu)(tu)廣泛。電(dian)磁閥雖有先(xian)天不足,優點仍十分突(tu)出,所以(yi)就設計(ji)成多種(zhong)多樣的產品,滿足各種(zhong)不同的需求,用(yong)途(tu)(tu)極為(wei)廣泛。電(dian)磁閥技術(shu)的進(jin)步也都是圍(wei)繞著如何克服先(xian)天不足,如何更好地發(fa)揮固有優勢而展開。 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 |
