意大利ATOS電磁換向閥的特點: (1)外漏堵絕,內漏易(yi)控(kong),使(shi)用(yong)安全(quan)。內外泄漏是危及安全(quan)的(de)要(yao)素。其它自控(kong)閥(fa)(fa)通常將(jiang)閥(fa)(fa)桿(gan)伸(shen)出,由電(dian)(dian)動(dong)(dong)(dong)、氣動(dong)(dong)(dong)、液動(dong)(dong)(dong)執行機構(gou)控(kong)制閥(fa)(fa)芯(xin)的(de)轉動(dong)(dong)(dong)或移動(dong)(dong)(dong)。這都(dou)要(yao)解決長(chang)期動(dong)(dong)(dong)作閥(fa)(fa)桿(gan)動(dong)(dong)(dong)密封的(de)外泄漏難題;唯有電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)是用(yong)電(dian)(dian)磁(ci)(ci)(ci)力(li)作用(yong)于密封在(zai)電(dian)(dian)動(dong)(dong)(dong)調(diao)節閥(fa)(fa)隔磁(ci)(ci)(ci)套管內的(de)鐵芯(xin)完成,不(bu)存在(zai)動(dong)(dong)(dong)密封,所(suo)以外漏易(yi)堵絕。電(dian)(dian)動(dong)(dong)(dong)閥(fa)(fa)力(li)矩控(kong)制不(bu)易(yi),容易(yi)產生內漏,甚至拉斷閥(fa)(fa)桿(gan)頭部(bu);電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)的(de)結構(gou)型式容易(yi)控(kong)制內泄漏,直至降為零(ling)。所(suo)以,電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)使(shi)用(yong)特別安全(quan),尤其適用(yong)于腐蝕(shi)性(xing)、有毒(du)或高低溫的(de)介(jie)質。 (2)系統簡單,便(bian)接電(dian)腦,價(jia)格(ge)低(di)謙(qian)。電(dian)磁(ci)閥本身(shen)結構簡單,價(jia)格(ge)也低(di),比起調節閥等(deng)其(qi)它種(zhong)類執行器易于安裝維護。更顯著的(de)是所(suo)組成的(de)自控(kong)系統簡單得多,價(jia)格(ge)要低(di)得多。由于電(dian)磁(ci)閥是開關信(xin)號控(kong)制,與工控(kong)計算機連接十分方便(bian)。在當今電(dian)腦普及,價(jia)格(ge)大幅下降的(de)時(shi)代,電(dian)磁(ci)閥的(de)優勢就(jiu)更加明顯。 (3)動作快遞(di),功率(lv)微小,外(wai)形輕巧(qiao)。電磁(ci)閥(fa)響應(ying)時間可以短(duan)至幾個(ge)毫(hao)秒,即使(shi)是(shi)先導式電磁(ci)閥(fa)也可以控制在幾十毫(hao)秒內(nei)。由于自成(cheng)回路,比之(zhi)其它自控閥(fa)反應(ying)更靈(ling)敏。設計得(de)當的(de)電磁(ci)閥(fa)線圈功率(lv)消耗很低,屬節能產品;還可做到只需觸(chu)發動作,自動保持閥(fa)位,平時一點也不耗電。電磁(ci)閥(fa)外(wai)形尺寸小,既節省空間,又輕巧(qiao)美觀。 (4)調節(jie)精(jing)度(du)(du)受(shou)限,適(shi)用(yong)(yong)介質受(shou)限。電磁(ci)閥通常只(zhi)有(you)開關(guan)兩種狀(zhuang)態,閥芯只(zhi)能處(chu)于兩個極限位(wei)置,不(bu)能連(lian)續調節(jie),(力圖突(tu)破的(de)新(xin)構思不(bu)少(shao),但還(huan)都處(chu)于試驗(yan)試用(yong)(yong)階段)所(suo)以調節(jie)精(jing)度(du)(du)還(huan)受(shou)到一(yi)定限制。電磁(ci)閥對介質潔(jie)凈度(du)(du)有(you)較(jiao)(jiao)高要(yao)求,含顆粒狀(zhuang)的(de)介質不(bu)能適(shi)用(yong)(yong),如屬(shu)雜質須先濾去。另外,粘(zhan)稠狀(zhuang)介質不(bu)能適(shi)用(yong)(yong),而且,特定的(de)產品適(shi)用(yong)(yong)的(de)介質粘(zhan)度(du)(du)范圍(wei)相對較(jiao)(jiao)窄。 (5)型號多樣,用(yong)途廣泛(fan)。電磁閥(fa)雖有先天不(bu)足,優點仍十分突出,所(suo)以就設(she)計成多種(zhong)多樣的(de)產品,滿足各(ge)種(zhong)不(bu)同的(de)需求(qiu),用(yong)途極為廣泛(fan)。電磁閥(fa)技術的(de)進步也(ye)都(dou)是圍繞著如何(he)克服先天不(bu)足,如何(he)更(geng)好(hao)地發揮固有優勢而展開(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 |
