意大利ATOS電磁換向閥的特點: (1)外漏(lou)堵絕(jue),內漏(lou)易控(kong),使(shi)用(yong)安全。內外泄漏(lou)是危及(ji)安全的要素。其它自控(kong)閥(fa)(fa)通(tong)常(chang)將閥(fa)(fa)桿(gan)伸出,由(you)電(dian)動(dong)(dong)(dong)(dong)、氣動(dong)(dong)(dong)(dong)、液動(dong)(dong)(dong)(dong)執行機構控(kong)制閥(fa)(fa)芯的轉動(dong)(dong)(dong)(dong)或移動(dong)(dong)(dong)(dong)。這都(dou)要解決長期動(dong)(dong)(dong)(dong)作閥(fa)(fa)桿(gan)動(dong)(dong)(dong)(dong)密封的外泄漏(lou)難題;唯有電(dian)磁(ci)閥(fa)(fa)是用(yong)電(dian)磁(ci)力作用(yong)于密封在(zai)電(dian)動(dong)(dong)(dong)(dong)調節(jie)閥(fa)(fa)隔磁(ci)套管內的鐵(tie)芯完(wan)成(cheng),不存在(zai)動(dong)(dong)(dong)(dong)密封,所以外漏(lou)易堵絕(jue)。電(dian)動(dong)(dong)(dong)(dong)閥(fa)(fa)力矩控(kong)制不易,容易產生內漏(lou),甚(shen)至拉斷(duan)閥(fa)(fa)桿(gan)頭(tou)部;電(dian)磁(ci)閥(fa)(fa)的結構型式容易控(kong)制內泄漏(lou),直至降為(wei)零(ling)。所以,電(dian)磁(ci)閥(fa)(fa)使(shi)用(yong)特別安全,尤其適用(yong)于腐蝕性、有毒或高低溫的介質(zhi)。 (2)系統簡單,便接電(dian)(dian)(dian)腦,價格(ge)低(di)謙(qian)。電(dian)(dian)(dian)磁(ci)閥(fa)本身結(jie)構簡單,價格(ge)也低(di),比起調節閥(fa)等其(qi)它種類執行器易于安裝維護。更顯(xian)著的是所組成的自控(kong)(kong)系統簡單得(de)多,價格(ge)要低(di)得(de)多。由于電(dian)(dian)(dian)磁(ci)閥(fa)是開關信號(hao)控(kong)(kong)制,與工控(kong)(kong)計算機連接十分方便。在當今電(dian)(dian)(dian)腦普及,價格(ge)大(da)幅下降的時代,電(dian)(dian)(dian)磁(ci)閥(fa)的優勢就更加明顯(xian)。 (3)動作(zuo)(zuo)快遞,功率(lv)微小,外形輕巧(qiao)。電磁(ci)閥響應(ying)時(shi)(shi)間(jian)可(ke)以(yi)(yi)短(duan)至幾個毫秒,即(ji)使是先導(dao)式電磁(ci)閥也可(ke)以(yi)(yi)控(kong)制在幾十(shi)毫秒內。由于(yu)自成回路,比之其(qi)它自控(kong)閥反應(ying)更靈(ling)敏。設(she)計(ji)得(de)當的電磁(ci)閥線圈功率(lv)消(xiao)耗很低,屬(shu)節(jie)能產品(pin);還可(ke)做到(dao)只需觸發(fa)動作(zuo)(zuo),自動保持閥位,平時(shi)(shi)一點也不(bu)耗電。電磁(ci)閥外形尺寸(cun)小,既節(jie)省空間(jian),又輕巧(qiao)美觀(guan)。 (4)調節(jie)(jie)精度受(shou)(shou)限,適用介質受(shou)(shou)限。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)個極限位(wei)置,不(bu)能連續調節(jie)(jie),(力圖突破(po)的新構(gou)思不(bu)少,但(dan)還(huan)都處(chu)于試驗試用階段)所以調節(jie)(jie)精度還(huan)受(shou)(shou)到一定限制。電磁閥(fa)對(dui)介質潔(jie)凈度有較(jiao)高(gao)要求,含顆粒(li)狀的介質不(bu)能適用,如(ru)屬雜(za)質須(xu)先(xian)濾去。另外,粘稠狀介質不(bu)能適用,而(er)且,特定的產(chan)品適用的介質粘度范圍相(xiang)對(dui)較(jiao)窄(zhai)。 (5)型(xing)號多樣(yang),用(yong)途廣泛。電磁閥(fa)(fa)雖有先天不足(zu),優點仍十分突(tu)出,所(suo)以(yi)就設(she)計(ji)成多種多樣(yang)的(de)(de)產品(pin),滿足(zu)各種不同的(de)(de)需求,用(yong)途極為廣泛。電磁閥(fa)(fa)技術的(de)(de)進步也都是圍(wei)繞著如何(he)克(ke)服(fu)先天不足(zu),如何(he)更好地(di)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 |
