意大利ATOS電磁換向閥的特點: (1)外漏堵絕,內(nei)漏易(yi)控(kong),使用(yong)(yong)安全(quan)。內(nei)外泄漏是(shi)危(wei)及安全(quan)的(de)(de)要(yao)素。其(qi)它自控(kong)閥(fa)(fa)通常將閥(fa)(fa)桿(gan)伸出,由電動(dong)(dong)(dong)、氣動(dong)(dong)(dong)、液動(dong)(dong)(dong)執(zhi)行機構控(kong)制(zhi)閥(fa)(fa)芯的(de)(de)轉動(dong)(dong)(dong)或移動(dong)(dong)(dong)。這都要(yao)解決長期動(dong)(dong)(dong)作閥(fa)(fa)桿(gan)動(dong)(dong)(dong)密(mi)封(feng)的(de)(de)外泄漏難(nan)題;唯有電磁(ci)閥(fa)(fa)是(shi)用(yong)(yong)電磁(ci)力作用(yong)(yong)于(yu)密(mi)封(feng)在(zai)電動(dong)(dong)(dong)調節閥(fa)(fa)隔磁(ci)套管內(nei)的(de)(de)鐵芯完(wan)成,不存在(zai)動(dong)(dong)(dong)密(mi)封(feng),所(suo)以(yi)外漏易(yi)堵絕。電動(dong)(dong)(dong)閥(fa)(fa)力矩控(kong)制(zhi)不易(yi),容(rong)易(yi)產生(sheng)內(nei)漏,甚至拉斷閥(fa)(fa)桿(gan)頭部;電磁(ci)閥(fa)(fa)的(de)(de)結構型式容(rong)易(yi)控(kong)制(zhi)內(nei)泄漏,直(zhi)至降(jiang)為零。所(suo)以(yi),電磁(ci)閥(fa)(fa)使用(yong)(yong)特別(bie)安全(quan),尤其(qi)適用(yong)(yong)于(yu)腐蝕(shi)性、有毒或高低(di)溫的(de)(de)介(jie)質。 (2)系統簡(jian)單(dan),便接電腦,價格(ge)低(di)謙。電磁(ci)(ci)閥(fa)本身結構簡(jian)單(dan),價格(ge)也低(di),比起調節閥(fa)等其它種類執行器易于(yu)安裝維(wei)護(hu)。更顯著的(de)是所(suo)組成(cheng)的(de)自控系統簡(jian)單(dan)得(de)(de)多,價格(ge)要低(di)得(de)(de)多。由于(yu)電磁(ci)(ci)閥(fa)是開關信(xin)號控制,與工控計算機連(lian)接十分方便。在當(dang)今電腦普(pu)及,價格(ge)大(da)幅下降的(de)時代,電磁(ci)(ci)閥(fa)的(de)優(you)勢就(jiu)更加(jia)明(ming)顯。 (3)動作(zuo)快遞,功率(lv)微小,外形輕(qing)巧。電(dian)磁(ci)閥(fa)響應時(shi)間(jian)可(ke)以短至幾個毫秒,即(ji)使是先導式電(dian)磁(ci)閥(fa)也可(ke)以控(kong)制在幾十毫秒內。由于(yu)自成(cheng)回路,比之(zhi)其它自控(kong)閥(fa)反應更(geng)靈敏。設(she)計得當的電(dian)磁(ci)閥(fa)線(xian)圈(quan)功率(lv)消耗(hao)很低,屬(shu)節能產品;還可(ke)做到只需觸發動作(zuo),自動保持(chi)閥(fa)位,平時(shi)一點也不耗(hao)電(dian)。電(dian)磁(ci)閥(fa)外形尺寸小,既節省空間(jian),又輕(qing)巧美觀(guan)。 (4)調節(jie)精(jing)(jing)度(du)受(shou)限(xian),適(shi)用介(jie)質(zhi)受(shou)限(xian)。電磁閥(fa)通常只(zhi)有(you)開關兩種狀(zhuang)態(tai),閥(fa)芯只(zhi)能(neng)處于(yu)兩個極限(xian)位置,不(bu)(bu)能(neng)連續調節(jie),(力圖突破的新構思不(bu)(bu)少,但還都處于(yu)試驗試用階段)所以調節(jie)精(jing)(jing)度(du)還受(shou)到一定限(xian)制。電磁閥(fa)對(dui)(dui)介(jie)質(zhi)潔凈度(du)有(you)較高要求,含顆粒狀(zhuang)的介(jie)質(zhi)不(bu)(bu)能(neng)適(shi)用,如屬雜質(zhi)須先濾去(qu)。另(ling)外(wai),粘稠狀(zhuang)介(jie)質(zhi)不(bu)(bu)能(neng)適(shi)用,而且,特定的產品適(shi)用的介(jie)質(zhi)粘度(du)范圍(wei)相對(dui)(dui)較窄。 (5)型號多(duo)(duo)樣,用途廣泛。電(dian)磁閥雖有先天不(bu)足,優(you)點仍十分突出,所以就(jiu)設計(ji)成多(duo)(duo)種多(duo)(duo)樣的(de)產(chan)品,滿足各種不(bu)同的(de)需求(qiu),用途極為廣泛。電(dian)磁閥技術的(de)進(jin)步(bu)也(ye)都(dou)是圍繞著如何克(ke)服(fu)先天不(bu)足,如何更好地發揮固有優(you)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 |
