意大利ATOS電磁換向閥的特點: (1)外(wai)(wai)漏(lou)堵絕(jue),內(nei)漏(lou)易(yi)控,使(shi)用(yong)安全(quan)。內(nei)外(wai)(wai)泄漏(lou)是危及安全(quan)的要素。其它(ta)自(zi)控閥(fa)(fa)通常將閥(fa)(fa)桿伸出,由(you)電(dian)(dian)動(dong)(dong)、氣動(dong)(dong)、液(ye)動(dong)(dong)執行機構(gou)控制閥(fa)(fa)芯的轉動(dong)(dong)或移動(dong)(dong)。這都要解(jie)決長(chang)期動(dong)(dong)作閥(fa)(fa)桿動(dong)(dong)密(mi)封的外(wai)(wai)泄漏(lou)難題;唯有電(dian)(dian)磁(ci)閥(fa)(fa)是用(yong)電(dian)(dian)磁(ci)力作用(yong)于(yu)密(mi)封在電(dian)(dian)動(dong)(dong)調節閥(fa)(fa)隔磁(ci)套(tao)管內(nei)的鐵芯完成,不(bu)存在動(dong)(dong)密(mi)封,所以外(wai)(wai)漏(lou)易(yi)堵絕(jue)。電(dian)(dian)動(dong)(dong)閥(fa)(fa)力矩控制不(bu)易(yi),容易(yi)產生(sheng)內(nei)漏(lou),甚(shen)至(zhi)(zhi)拉(la)斷閥(fa)(fa)桿頭部;電(dian)(dian)磁(ci)閥(fa)(fa)的結構(gou)型式容易(yi)控制內(nei)泄漏(lou),直至(zhi)(zhi)降為零。所以,電(dian)(dian)磁(ci)閥(fa)(fa)使(shi)用(yong)特別安全(quan),尤(you)其適用(yong)于(yu)腐蝕性、有毒或高(gao)低溫的介質。 (2)系統簡(jian)單(dan),便接電(dian)(dian)腦(nao),價(jia)格(ge)低謙。電(dian)(dian)磁(ci)閥本(ben)身結構(gou)簡(jian)單(dan),價(jia)格(ge)也(ye)低,比(bi)起調節(jie)閥等其它種類(lei)執行器(qi)易于(yu)安裝維護。更顯(xian)著的(de)是所組成的(de)自(zi)控(kong)(kong)系統簡(jian)單(dan)得(de)多,價(jia)格(ge)要低得(de)多。由于(yu)電(dian)(dian)磁(ci)閥是開關信(xin)號控(kong)(kong)制,與工控(kong)(kong)計算機連(lian)接十分方便。在(zai)當今電(dian)(dian)腦(nao)普(pu)及,價(jia)格(ge)大幅下降的(de)時代,電(dian)(dian)磁(ci)閥的(de)優勢就更加明顯(xian)。 (3)動作(zuo)快遞,功(gong)率微小(xiao),外形輕巧。電(dian)磁(ci)閥(fa)(fa)響應時間(jian)可(ke)以短(duan)至幾個毫秒,即使是(shi)先導式電(dian)磁(ci)閥(fa)(fa)也(ye)(ye)可(ke)以控(kong)制(zhi)在(zai)幾十毫秒內。由于(yu)自成回路,比(bi)之其它自控(kong)閥(fa)(fa)反(fan)應更(geng)靈敏。設(she)計得當的電(dian)磁(ci)閥(fa)(fa)線圈功(gong)率消耗很低,屬節(jie)能產品(pin);還(huan)可(ke)做到只需觸發動作(zuo),自動保持閥(fa)(fa)位,平時一點也(ye)(ye)不(bu)耗電(dian)。電(dian)磁(ci)閥(fa)(fa)外形尺寸小(xiao),既(ji)節(jie)省(sheng)空間(jian),又輕巧美(mei)觀。 (4)調(diao)(diao)節精度受限(xian)(xian),適(shi)(shi)(shi)用介質(zhi)(zhi)受限(xian)(xian)。電磁閥(fa)通常只有開關(guan)兩(liang)種狀態,閥(fa)芯只能處(chu)于兩(liang)個(ge)極限(xian)(xian)位置,不(bu)能連續(xu)調(diao)(diao)節,(力(li)圖突破的新構思不(bu)少(shao),但還都處(chu)于試驗試用階段)所以調(diao)(diao)節精度還受到一定限(xian)(xian)制。電磁閥(fa)對(dui)介質(zhi)(zhi)潔凈度有較(jiao)高要求,含顆粒狀的介質(zhi)(zhi)不(bu)能適(shi)(shi)(shi)用,如屬雜(za)質(zhi)(zhi)須先濾(lv)去。另(ling)外,粘稠(chou)狀介質(zhi)(zhi)不(bu)能適(shi)(shi)(shi)用,而且,特定的產(chan)品適(shi)(shi)(shi)用的介質(zhi)(zhi)粘度范圍相對(dui)較(jiao)窄(zhai)。 (5)型號多(duo)樣(yang)(yang),用途廣泛。電(dian)磁閥(fa)雖有先天(tian)不足(zu),優點(dian)仍十分(fen)突出(chu),所以(yi)就(jiu)設計成多(duo)種(zhong)多(duo)樣(yang)(yang)的產品,滿足(zu)各種(zhong)不同(tong)的需求,用途極為(wei)廣泛。電(dian)磁閥(fa)技術的進步也都是圍(wei)繞著如何克服(fu)先天(tian)不足(zu),如何更好地發揮固(gu)有優勢(shi)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 |
