意大利ATOS電磁換向閥的特點: (1)外(wai)(wai)漏(lou)(lou)堵絕,內(nei)(nei)漏(lou)(lou)易控(kong)(kong),使用安全(quan)。內(nei)(nei)外(wai)(wai)泄(xie)漏(lou)(lou)是危及(ji)安全(quan)的(de)要素(su)。其它(ta)自控(kong)(kong)閥(fa)(fa)(fa)通常將閥(fa)(fa)(fa)桿(gan)(gan)伸出,由電動(dong)(dong)(dong)、氣動(dong)(dong)(dong)、液動(dong)(dong)(dong)執行機構(gou)控(kong)(kong)制閥(fa)(fa)(fa)芯(xin)的(de)轉動(dong)(dong)(dong)或移動(dong)(dong)(dong)。這都要解決長期(qi)動(dong)(dong)(dong)作閥(fa)(fa)(fa)桿(gan)(gan)動(dong)(dong)(dong)密(mi)封(feng)的(de)外(wai)(wai)泄(xie)漏(lou)(lou)難題;唯有(you)電磁(ci)閥(fa)(fa)(fa)是用電磁(ci)力(li)(li)作用于密(mi)封(feng)在(zai)電動(dong)(dong)(dong)調節閥(fa)(fa)(fa)隔磁(ci)套管內(nei)(nei)的(de)鐵芯(xin)完成,不存在(zai)動(dong)(dong)(dong)密(mi)封(feng),所以(yi)外(wai)(wai)漏(lou)(lou)易堵絕。電動(dong)(dong)(dong)閥(fa)(fa)(fa)力(li)(li)矩控(kong)(kong)制不易,容(rong)易產生內(nei)(nei)漏(lou)(lou),甚至(zhi)拉斷閥(fa)(fa)(fa)桿(gan)(gan)頭(tou)部;電磁(ci)閥(fa)(fa)(fa)的(de)結構(gou)型式容(rong)易控(kong)(kong)制內(nei)(nei)泄(xie)漏(lou)(lou),直至(zhi)降為零。所以(yi),電磁(ci)閥(fa)(fa)(fa)使用特別安全(quan),尤其適用于腐蝕(shi)性、有(you)毒(du)或高低溫(wen)的(de)介質(zhi)。 (2)系統(tong)簡(jian)單(dan),便接(jie)電(dian)(dian)腦(nao),價格低謙。電(dian)(dian)磁(ci)閥本身結構簡(jian)單(dan),價格也(ye)低,比(bi)起調節閥等其它種(zhong)類執行器(qi)易于安裝(zhuang)維(wei)護(hu)。更顯(xian)(xian)著的(de)是(shi)所組(zu)成(cheng)的(de)自控(kong)系統(tong)簡(jian)單(dan)得多(duo),價格要(yao)低得多(duo)。由(you)于電(dian)(dian)磁(ci)閥是(shi)開關信號控(kong)制,與工控(kong)計算機連接(jie)十分(fen)方(fang)便。在當(dang)今電(dian)(dian)腦(nao)普(pu)及,價格大幅下(xia)降的(de)時代(dai),電(dian)(dian)磁(ci)閥的(de)優勢就更加明顯(xian)(xian)。 (3)動(dong)(dong)作快遞,功率微(wei)小,外形輕巧(qiao)。電磁閥(fa)(fa)響應時(shi)間可(ke)以(yi)短至幾個毫(hao)秒(miao),即(ji)使是(shi)先導式電磁閥(fa)(fa)也(ye)可(ke)以(yi)控制(zhi)在幾十毫(hao)秒(miao)內。由于自(zi)(zi)成(cheng)回路,比之其它自(zi)(zi)控閥(fa)(fa)反應更(geng)靈敏(min)。設計得當的(de)電磁閥(fa)(fa)線(xian)圈功率消耗很低,屬節能產品;還可(ke)做到只需觸發(fa)動(dong)(dong)作,自(zi)(zi)動(dong)(dong)保持閥(fa)(fa)位(wei),平時(shi)一點也(ye)不耗電。電磁閥(fa)(fa)外形尺寸小,既節省空間,又輕巧(qiao)美觀。 (4)調(diao)節精度受限,適(shi)(shi)用(yong)介(jie)(jie)質(zhi)受限。電(dian)磁閥(fa)通常只有(you)開關兩種(zhong)狀態,閥(fa)芯只能處于兩個(ge)極限位置(zhi),不(bu)(bu)(bu)能連(lian)續調(diao)節,(力圖突(tu)破(po)的(de)(de)新構思(si)不(bu)(bu)(bu)少,但還都處于試驗試用(yong)階段)所以調(diao)節精度還受到(dao)一定限制(zhi)。電(dian)磁閥(fa)對(dui)介(jie)(jie)質(zhi)潔凈度有(you)較高(gao)要求(qiu),含(han)顆粒(li)狀的(de)(de)介(jie)(jie)質(zhi)不(bu)(bu)(bu)能適(shi)(shi)用(yong),如屬雜質(zhi)須先濾去。另外(wai),粘稠狀介(jie)(jie)質(zhi)不(bu)(bu)(bu)能適(shi)(shi)用(yong),而且,特(te)定的(de)(de)產(chan)品適(shi)(shi)用(yong)的(de)(de)介(jie)(jie)質(zhi)粘度范圍相對(dui)較窄。 (5)型號多(duo)樣,用途廣泛(fan)。電磁閥雖有先(xian)天不足,優(you)點仍十(shi)分突出,所以就設(she)計(ji)成多(duo)種多(duo)樣的(de)產(chan)品(pin),滿足各種不同的(de)需(xu)求,用途極為廣泛(fan)。電磁閥技術(shu)的(de)進步也(ye)都是圍繞(rao)著如(ru)何(he)克服先(xian)天不足,如(ru)何(he)更好地發揮固有優(you)勢而展(zhan)開(kai)。 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 |
