意大利ATOS電磁換向閥的特點: (1)外漏(lou)堵絕,內(nei)漏(lou)易(yi)控(kong)(kong)(kong),使(shi)(shi)用(yong)安全(quan)。內(nei)外泄漏(lou)是(shi)危及安全(quan)的(de)要素。其(qi)它自控(kong)(kong)(kong)閥(fa)(fa)(fa)通常將(jiang)閥(fa)(fa)(fa)桿伸(shen)出,由(you)電(dian)(dian)動(dong)(dong)、氣動(dong)(dong)、液動(dong)(dong)執行(xing)機構控(kong)(kong)(kong)制(zhi)閥(fa)(fa)(fa)芯的(de)轉(zhuan)動(dong)(dong)或移動(dong)(dong)。這都(dou)要解決長期動(dong)(dong)作(zuo)閥(fa)(fa)(fa)桿動(dong)(dong)密封的(de)外泄漏(lou)難題;唯有電(dian)(dian)磁閥(fa)(fa)(fa)是(shi)用(yong)電(dian)(dian)磁力(li)作(zuo)用(yong)于密封在電(dian)(dian)動(dong)(dong)調(diao)節閥(fa)(fa)(fa)隔磁套(tao)管內(nei)的(de)鐵芯完成,不存(cun)在動(dong)(dong)密封,所以外漏(lou)易(yi)堵絕。電(dian)(dian)動(dong)(dong)閥(fa)(fa)(fa)力(li)矩(ju)控(kong)(kong)(kong)制(zhi)不易(yi),容易(yi)產生內(nei)漏(lou),甚至拉(la)斷閥(fa)(fa)(fa)桿頭(tou)部;電(dian)(dian)磁閥(fa)(fa)(fa)的(de)結(jie)構型式(shi)容易(yi)控(kong)(kong)(kong)制(zhi)內(nei)泄漏(lou),直至降(jiang)為零(ling)。所以,電(dian)(dian)磁閥(fa)(fa)(fa)使(shi)(shi)用(yong)特別安全(quan),尤其(qi)適用(yong)于腐蝕性(xing)、有毒或高(gao)低溫的(de)介(jie)質。 (2)系(xi)統(tong)簡單(dan),便(bian)接電(dian)(dian)腦(nao)(nao),價(jia)格低(di)謙(qian)。電(dian)(dian)磁閥(fa)本身結構(gou)簡單(dan),價(jia)格也低(di),比起調(diao)節閥(fa)等其它種(zhong)類執行器易于安裝維護。更(geng)顯著的(de)是(shi)所組成的(de)自控(kong)系(xi)統(tong)簡單(dan)得多,價(jia)格要(yao)低(di)得多。由于電(dian)(dian)磁閥(fa)是(shi)開(kai)關信號控(kong)制,與工控(kong)計算機(ji)連接十分方便(bian)。在當(dang)今電(dian)(dian)腦(nao)(nao)普及,價(jia)格大幅下降(jiang)的(de)時代(dai),電(dian)(dian)磁閥(fa)的(de)優勢就更(geng)加明(ming)顯。 (3)動(dong)作快遞(di),功率微(wei)小,外形輕巧(qiao)。電(dian)(dian)磁(ci)(ci)閥(fa)響(xiang)應時間可(ke)以短至幾個(ge)毫秒,即(ji)使是先導(dao)式電(dian)(dian)磁(ci)(ci)閥(fa)也可(ke)以控制在幾十毫秒內。由于自(zi)成回路,比之其它自(zi)控閥(fa)反應更靈敏。設計(ji)得(de)當的電(dian)(dian)磁(ci)(ci)閥(fa)線圈功率消耗(hao)很低,屬節(jie)能產品;還可(ke)做(zuo)到只需觸發動(dong)作,自(zi)動(dong)保持(chi)閥(fa)位,平時一點也不(bu)耗(hao)電(dian)(dian)。電(dian)(dian)磁(ci)(ci)閥(fa)外形尺寸小,既節(jie)省空間,又輕巧(qiao)美觀。 (4)調節精度受限,適(shi)(shi)(shi)用(yong)介(jie)質(zhi)受限。電(dian)磁(ci)閥通常(chang)只(zhi)有開關兩種狀(zhuang)態,閥芯只(zhi)能處于(yu)兩個(ge)極限位置,不(bu)能連續調節,(力圖突破的新構思不(bu)少,但還都處于(yu)試驗(yan)試用(yong)階段)所以調節精度還受到一定限制(zhi)。電(dian)磁(ci)閥對介(jie)質(zhi)潔(jie)凈(jing)度有較高要求,含(han)顆(ke)粒狀(zhuang)的介(jie)質(zhi)不(bu)能適(shi)(shi)(shi)用(yong),如(ru)屬雜質(zhi)須先濾去。另外(wai),粘稠(chou)狀(zhuang)介(jie)質(zhi)不(bu)能適(shi)(shi)(shi)用(yong),而(er)且,特定的產品適(shi)(shi)(shi)用(yong)的介(jie)質(zhi)粘度范圍相(xiang)對較窄。 (5)型號(hao)多(duo)樣,用途廣泛。電磁閥雖有先(xian)天不(bu)足(zu)(zu),優(you)點仍十分突出,所以就設計成多(duo)種(zhong)多(duo)樣的(de)產品(pin),滿足(zu)(zu)各(ge)種(zhong)不(bu)同的(de)需(xu)求(qiu),用途極(ji)為廣泛。電磁閥技術的(de)進步也都是圍繞著如何克(ke)服先(xian)天不(bu)足(zu)(zu),如何更好地發(fa)揮(hui)固有優(you)勢而展開(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 |
