意大利ATOS電磁換向閥的特點: (1)外漏(lou)堵(du)絕(jue),內(nei)(nei)漏(lou)易控(kong)(kong),使用(yong)安全(quan)。內(nei)(nei)外泄(xie)漏(lou)是危及安全(quan)的(de)(de)(de)要素。其它自控(kong)(kong)閥(fa)通常將閥(fa)桿(gan)伸出,由電(dian)動(dong)、氣動(dong)、液動(dong)執行機(ji)構控(kong)(kong)制(zhi)閥(fa)芯的(de)(de)(de)轉動(dong)或移動(dong)。這都要解決(jue)長(chang)期動(dong)作閥(fa)桿(gan)動(dong)密封的(de)(de)(de)外泄(xie)漏(lou)難題;唯有電(dian)磁(ci)(ci)閥(fa)是用(yong)電(dian)磁(ci)(ci)力(li)作用(yong)于(yu)密封在電(dian)動(dong)調(diao)節閥(fa)隔磁(ci)(ci)套(tao)管(guan)內(nei)(nei)的(de)(de)(de)鐵芯完(wan)成(cheng),不存在動(dong)密封,所(suo)以(yi)外漏(lou)易堵(du)絕(jue)。電(dian)動(dong)閥(fa)力(li)矩控(kong)(kong)制(zhi)不易,容易產生內(nei)(nei)漏(lou),甚至拉斷閥(fa)桿(gan)頭部;電(dian)磁(ci)(ci)閥(fa)的(de)(de)(de)結構型式容易控(kong)(kong)制(zhi)內(nei)(nei)泄(xie)漏(lou),直至降(jiang)為零。所(suo)以(yi),電(dian)磁(ci)(ci)閥(fa)使用(yong)特別(bie)安全(quan),尤其適用(yong)于(yu)腐(fu)蝕性、有毒或高低溫的(de)(de)(de)介質。 (2)系(xi)統(tong)簡(jian)單(dan),便接(jie)電(dian)腦,價格(ge)低謙。電(dian)磁(ci)(ci)閥(fa)本身結構簡(jian)單(dan),價格(ge)也低,比起調節閥(fa)等其(qi)它種類執行器易于安(an)裝(zhuang)維護。更(geng)顯(xian)著的(de)是所組成(cheng)的(de)自控系(xi)統(tong)簡(jian)單(dan)得(de)多(duo)(duo),價格(ge)要低得(de)多(duo)(duo)。由于電(dian)磁(ci)(ci)閥(fa)是開關信號控制,與(yu)工控計算機連接(jie)十分(fen)方(fang)便。在(zai)當今電(dian)腦普(pu)及,價格(ge)大幅下降的(de)時代,電(dian)磁(ci)(ci)閥(fa)的(de)優(you)勢就更(geng)加(jia)明(ming)顯(xian)。 (3)動(dong)作快遞,功率微小(xiao),外(wai)(wai)形輕巧。電磁閥(fa)響應時(shi)間可以短(duan)至(zhi)幾個毫秒(miao),即使是(shi)先導式(shi)電磁閥(fa)也(ye)可以控制在幾十毫秒(miao)內。由于自(zi)(zi)成(cheng)回路,比(bi)之其它自(zi)(zi)控閥(fa)反(fan)應更靈敏(min)。設(she)計得當的電磁閥(fa)線圈功率消(xiao)耗很低,屬節(jie)能(neng)產(chan)品;還可做到只需觸發動(dong)作,自(zi)(zi)動(dong)保(bao)持閥(fa)位,平(ping)時(shi)一點(dian)也(ye)不耗電。電磁閥(fa)外(wai)(wai)形尺寸小(xiao),既(ji)節(jie)省空間,又輕巧美觀。 (4)調(diao)節精度受(shou)限(xian)(xian),適(shi)(shi)用介(jie)質(zhi)受(shou)限(xian)(xian)。電(dian)磁(ci)閥(fa)通(tong)常只有開關兩種狀(zhuang)態,閥(fa)芯只能(neng)處(chu)于兩個極(ji)限(xian)(xian)位(wei)置,不(bu)能(neng)連續調(diao)節,(力圖突破的新(xin)構思(si)不(bu)少,但(dan)還都處(chu)于試驗試用階段)所(suo)以調(diao)節精度還受(shou)到一定限(xian)(xian)制。電(dian)磁(ci)閥(fa)對(dui)介(jie)質(zhi)潔(jie)凈度有較高(gao)要求,含顆粒狀(zhuang)的介(jie)質(zhi)不(bu)能(neng)適(shi)(shi)用,如屬雜質(zhi)須先濾去。另外,粘稠(chou)狀(zhuang)介(jie)質(zhi)不(bu)能(neng)適(shi)(shi)用,而且,特定的產品適(shi)(shi)用的介(jie)質(zhi)粘度范(fan)圍相對(dui)較窄(zhai)。 (5)型號多樣(yang)(yang),用(yong)途(tu)廣(guang)泛。電磁閥雖有(you)先(xian)天不足,優點仍十分突出,所(suo)以就設計成多種(zhong)多樣(yang)(yang)的產品,滿足各種(zhong)不同的需求,用(yong)途(tu)極為廣(guang)泛。電磁閥技術的進步也都是(shi)圍繞著如何(he)克服先(xian)天不足,如何(he)更好地發揮固有(you)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 |
