意大利ATOS電磁換向閥的特點: (1)外(wai)漏堵(du)絕(jue),內(nei)漏易(yi)控,使(shi)用安全。內(nei)外(wai)泄漏是危及安全的(de)要(yao)素。其它自控閥(fa)(fa)(fa)通(tong)常將閥(fa)(fa)(fa)桿(gan)伸出,由電(dian)(dian)動(dong)(dong)(dong)(dong)、氣動(dong)(dong)(dong)(dong)、液動(dong)(dong)(dong)(dong)執行機構控制(zhi)(zhi)閥(fa)(fa)(fa)芯的(de)轉(zhuan)動(dong)(dong)(dong)(dong)或移動(dong)(dong)(dong)(dong)。這都要(yao)解決長期動(dong)(dong)(dong)(dong)作(zuo)(zuo)閥(fa)(fa)(fa)桿(gan)動(dong)(dong)(dong)(dong)密封(feng)的(de)外(wai)泄漏難(nan)題;唯有電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)是用電(dian)(dian)磁(ci)(ci)力作(zuo)(zuo)用于密封(feng)在電(dian)(dian)動(dong)(dong)(dong)(dong)調節閥(fa)(fa)(fa)隔磁(ci)(ci)套管內(nei)的(de)鐵芯完成,不(bu)存在動(dong)(dong)(dong)(dong)密封(feng),所(suo)以外(wai)漏易(yi)堵(du)絕(jue)。電(dian)(dian)動(dong)(dong)(dong)(dong)閥(fa)(fa)(fa)力矩(ju)控制(zhi)(zhi)不(bu)易(yi),容(rong)易(yi)產生(sheng)內(nei)漏,甚至拉(la)斷閥(fa)(fa)(fa)桿(gan)頭(tou)部;電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)的(de)結構型式容(rong)易(yi)控制(zhi)(zhi)內(nei)泄漏,直(zhi)至降為零。所(suo)以,電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)使(shi)用特別安全,尤其適用于腐蝕性、有毒或高(gao)低溫的(de)介(jie)質。 (2)系(xi)統簡(jian)單,便接電(dian)腦(nao)(nao),價(jia)(jia)格低(di)謙。電(dian)磁閥(fa)本(ben)身結構簡(jian)單,價(jia)(jia)格也低(di),比起調(diao)節閥(fa)等其它種類執行器易于安裝維(wei)護。更顯著(zhu)的是所組成的自控系(xi)統簡(jian)單得多,價(jia)(jia)格要低(di)得多。由(you)于電(dian)磁閥(fa)是開(kai)關信號控制,與工(gong)控計算機連接十分方便。在當今(jin)電(dian)腦(nao)(nao)普及,價(jia)(jia)格大幅下降(jiang)的時代,電(dian)磁閥(fa)的優(you)勢就更加明顯。 (3)動(dong)(dong)作快遞,功(gong)率微(wei)小,外(wai)形(xing)輕(qing)巧(qiao)。電磁(ci)閥響應時(shi)間(jian)可(ke)以(yi)短至幾個(ge)毫秒,即使(shi)是(shi)先(xian)導式(shi)電磁(ci)閥也可(ke)以(yi)控制在(zai)幾十毫秒內。由于自(zi)成回(hui)路,比之其它(ta)自(zi)控閥反應更靈敏。設計(ji)得當(dang)的(de)電磁(ci)閥線(xian)圈(quan)功(gong)率消耗(hao)很低(di),屬節能產品;還可(ke)做到只需觸(chu)發動(dong)(dong)作,自(zi)動(dong)(dong)保持閥位(wei),平時(shi)一點也不耗(hao)電。電磁(ci)閥外(wai)形(xing)尺寸小,既節省空間(jian),又輕(qing)巧(qiao)美(mei)觀(guan)。 (4)調節(jie)精(jing)度(du)受(shou)限,適(shi)用介質受(shou)限。電(dian)磁(ci)閥(fa)通常只有開關兩種(zhong)狀態,閥(fa)芯(xin)只能(neng)處于(yu)兩個極(ji)限位置,不能(neng)連續(xu)調節(jie),(力圖突破的(de)新構思不少(shao),但還都處于(yu)試驗試用階段)所以調節(jie)精(jing)度(du)還受(shou)到一(yi)定限制(zhi)。電(dian)磁(ci)閥(fa)對介質潔凈度(du)有較高要(yao)求,含顆粒(li)狀的(de)介質不能(neng)適(shi)用,如屬雜(za)質須(xu)先濾(lv)去。另外(wai),粘稠狀介質不能(neng)適(shi)用,而且,特(te)定的(de)產品適(shi)用的(de)介質粘度(du)范圍相對較窄(zhai)。 (5)型號(hao)多(duo)樣,用(yong)途廣(guang)泛。電(dian)磁閥(fa)雖有先(xian)天不足(zu),優點(dian)仍十分突出,所(suo)以就(jiu)設計(ji)成多(duo)種多(duo)樣的(de)產品,滿足(zu)各(ge)種不同的(de)需求,用(yong)途極為廣(guang)泛。電(dian)磁閥(fa)技術的(de)進(jin)步也都是圍繞著如(ru)何克服先(xian)天不足(zu),如(ru)何更(geng)好地發揮固有優勢而展(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 |
