意大利ATOS電磁換向閥的特點: (1)外(wai)漏堵(du)絕,內(nei)(nei)(nei)漏易(yi)控(kong)(kong),使用(yong)安全。內(nei)(nei)(nei)外(wai)泄(xie)漏是危及安全的(de)(de)要(yao)素。其它(ta)自控(kong)(kong)閥(fa)(fa)通常(chang)將(jiang)閥(fa)(fa)桿(gan)伸出,由電(dian)(dian)(dian)動(dong)、氣(qi)動(dong)、液動(dong)執行機構控(kong)(kong)制閥(fa)(fa)芯的(de)(de)轉(zhuan)動(dong)或移(yi)動(dong)。這都要(yao)解(jie)決長期(qi)動(dong)作閥(fa)(fa)桿(gan)動(dong)密(mi)封(feng)的(de)(de)外(wai)泄(xie)漏難題;唯有電(dian)(dian)(dian)磁(ci)閥(fa)(fa)是用(yong)電(dian)(dian)(dian)磁(ci)力作用(yong)于密(mi)封(feng)在(zai)電(dian)(dian)(dian)動(dong)調(diao)節閥(fa)(fa)隔磁(ci)套管內(nei)(nei)(nei)的(de)(de)鐵芯完成(cheng),不存(cun)在(zai)動(dong)密(mi)封(feng),所以外(wai)漏易(yi)堵(du)絕。電(dian)(dian)(dian)動(dong)閥(fa)(fa)力矩控(kong)(kong)制不易(yi),容(rong)(rong)易(yi)產(chan)生內(nei)(nei)(nei)漏,甚至拉斷(duan)閥(fa)(fa)桿(gan)頭部;電(dian)(dian)(dian)磁(ci)閥(fa)(fa)的(de)(de)結(jie)構型式容(rong)(rong)易(yi)控(kong)(kong)制內(nei)(nei)(nei)泄(xie)漏,直(zhi)至降為零。所以,電(dian)(dian)(dian)磁(ci)閥(fa)(fa)使用(yong)特別安全,尤其適用(yong)于腐蝕(shi)性(xing)、有毒或高低溫(wen)的(de)(de)介(jie)質(zhi)。 (2)系(xi)統(tong)簡(jian)單(dan),便接電腦(nao),價(jia)格(ge)低謙。電磁(ci)閥(fa)本身結構簡(jian)單(dan),價(jia)格(ge)也低,比起調(diao)節閥(fa)等其它(ta)種類執行器易于(yu)安裝維護。更(geng)(geng)顯著的(de)是所組成的(de)自控(kong)系(xi)統(tong)簡(jian)單(dan)得多,價(jia)格(ge)要低得多。由于(yu)電磁(ci)閥(fa)是開(kai)關信號控(kong)制,與工控(kong)計算(suan)機連接十分方便。在當今電腦(nao)普及,價(jia)格(ge)大幅下(xia)降的(de)時代,電磁(ci)閥(fa)的(de)優勢就更(geng)(geng)加明顯。 (3)動作(zuo)快遞,功率(lv)微小(xiao),外形(xing)輕(qing)巧(qiao)。電(dian)(dian)磁閥(fa)(fa)(fa)響應時間可(ke)以短至幾(ji)(ji)個毫(hao)秒,即使(shi)是先導式電(dian)(dian)磁閥(fa)(fa)(fa)也可(ke)以控制在幾(ji)(ji)十毫(hao)秒內。由于(yu)自(zi)(zi)成回路,比之其它自(zi)(zi)控閥(fa)(fa)(fa)反應更靈敏。設計得當的電(dian)(dian)磁閥(fa)(fa)(fa)線圈功率(lv)消(xiao)耗很(hen)低,屬節(jie)能產品;還可(ke)做(zuo)到只需(xu)觸(chu)發動作(zuo),自(zi)(zi)動保持(chi)閥(fa)(fa)(fa)位,平(ping)時一(yi)點也不耗電(dian)(dian)。電(dian)(dian)磁閥(fa)(fa)(fa)外形(xing)尺寸小(xiao),既節(jie)省空間,又輕(qing)巧(qiao)美觀(guan)。 (4)調(diao)節精度(du)受限,適(shi)用(yong)(yong)介(jie)質(zhi)受限。電磁閥通常只有開(kai)關兩種狀態(tai),閥芯(xin)只能(neng)處于(yu)(yu)兩個極限位置,不能(neng)連續調(diao)節,(力(li)圖突破(po)的(de)(de)新構思不少,但還(huan)(huan)都處于(yu)(yu)試驗(yan)試用(yong)(yong)階段)所以調(diao)節精度(du)還(huan)(huan)受到(dao)一定限制。電磁閥對(dui)介(jie)質(zhi)潔凈(jing)度(du)有較(jiao)高(gao)要(yao)求,含(han)顆粒狀的(de)(de)介(jie)質(zhi)不能(neng)適(shi)用(yong)(yong),如屬(shu)雜質(zhi)須先濾去。另外,粘稠狀介(jie)質(zhi)不能(neng)適(shi)用(yong)(yong),而(er)且,特定的(de)(de)產品適(shi)用(yong)(yong)的(de)(de)介(jie)質(zhi)粘度(du)范(fan)圍相對(dui)較(jiao)窄。 (5)型號多(duo)樣(yang),用途廣(guang)泛。電(dian)磁閥雖有(you)先天(tian)不(bu)足,優(you)點仍十分突出,所以就設(she)計(ji)成多(duo)種多(duo)樣(yang)的(de)產品,滿足各(ge)種不(bu)同的(de)需求,用途極為廣(guang)泛。電(dian)磁閥技術的(de)進步也都是圍繞著如何克服先天(tian)不(bu)足,如何更好地發(fa)揮固有(you)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 |
