意大利ATOS電磁換向閥的特點: (1)外漏(lou)(lou)(lou)(lou)堵(du)絕(jue),內(nei)漏(lou)(lou)(lou)(lou)易(yi)控(kong),使(shi)用安全(quan)。內(nei)外泄(xie)漏(lou)(lou)(lou)(lou)是(shi)危及安全(quan)的要素。其(qi)它自控(kong)閥通常將閥桿(gan)伸出,由電(dian)(dian)動(dong)(dong)(dong)、氣動(dong)(dong)(dong)、液動(dong)(dong)(dong)執行(xing)機構控(kong)制閥芯(xin)的轉動(dong)(dong)(dong)或移動(dong)(dong)(dong)。這(zhe)都要解決長期(qi)動(dong)(dong)(dong)作閥桿(gan)動(dong)(dong)(dong)密(mi)封的外泄(xie)漏(lou)(lou)(lou)(lou)難題;唯有(you)電(dian)(dian)磁閥是(shi)用電(dian)(dian)磁力作用于密(mi)封在(zai)電(dian)(dian)動(dong)(dong)(dong)調節(jie)閥隔磁套(tao)管內(nei)的鐵(tie)芯(xin)完成,不(bu)存在(zai)動(dong)(dong)(dong)密(mi)封,所以外漏(lou)(lou)(lou)(lou)易(yi)堵(du)絕(jue)。電(dian)(dian)動(dong)(dong)(dong)閥力矩控(kong)制不(bu)易(yi),容易(yi)產生(sheng)內(nei)漏(lou)(lou)(lou)(lou),甚至(zhi)拉斷閥桿(gan)頭部(bu);電(dian)(dian)磁閥的結(jie)構型(xing)式(shi)容易(yi)控(kong)制內(nei)泄(xie)漏(lou)(lou)(lou)(lou),直(zhi)至(zhi)降為(wei)零(ling)。所以,電(dian)(dian)磁閥使(shi)用特別(bie)安全(quan),尤其(qi)適(shi)用于腐蝕性、有(you)毒或高低(di)溫的介(jie)質。 (2)系統簡單,便(bian)接電(dian)腦,價(jia)格(ge)(ge)(ge)低謙。電(dian)磁閥(fa)本身結構簡單,價(jia)格(ge)(ge)(ge)也低,比(bi)起調節閥(fa)等其(qi)它種類執行器易于(yu)安裝維護。更顯著(zhu)的是所組成的自控系統簡單得(de)多(duo),價(jia)格(ge)(ge)(ge)要低得(de)多(duo)。由于(yu)電(dian)磁閥(fa)是開關(guan)信號控制(zhi),與工控計(ji)算(suan)機連接十分方便(bian)。在當(dang)今電(dian)腦普及,價(jia)格(ge)(ge)(ge)大(da)幅(fu)下降的時代,電(dian)磁閥(fa)的優勢就更加明顯。 (3)動作快(kuai)遞,功率(lv)微小,外形輕(qing)(qing)巧(qiao)。電(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)響應(ying)時間(jian)可(ke)以短至幾(ji)(ji)個毫秒(miao)(miao),即使是先導式電(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)也(ye)可(ke)以控制在幾(ji)(ji)十(shi)毫秒(miao)(miao)內。由于(yu)自成(cheng)回路(lu),比之其它自控閥(fa)(fa)(fa)反應(ying)更靈敏。設(she)計(ji)得當(dang)的(de)電(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)線圈功率(lv)消耗(hao)很低,屬節能(neng)產品;還可(ke)做到只需(xu)觸發(fa)動作,自動保持閥(fa)(fa)(fa)位,平時一點也(ye)不耗(hao)電(dian)。電(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)外形尺(chi)寸小,既節省空(kong)間(jian),又輕(qing)(qing)巧(qiao)美(mei)觀。 (4)調(diao)節(jie)精度受(shou)限,適(shi)用(yong)介(jie)(jie)質(zhi)(zhi)受(shou)限。電磁閥通常(chang)只有開(kai)關兩(liang)(liang)種狀態,閥芯只能(neng)處于(yu)兩(liang)(liang)個(ge)極限位置,不(bu)能(neng)連續(xu)調(diao)節(jie),(力圖突破的新構(gou)思(si)不(bu)少(shao),但還都處于(yu)試(shi)驗試(shi)用(yong)階(jie)段)所以調(diao)節(jie)精度還受(shou)到(dao)一定(ding)(ding)限制。電磁閥對介(jie)(jie)質(zhi)(zhi)潔凈度有較高(gao)要求,含顆粒狀的介(jie)(jie)質(zhi)(zhi)不(bu)能(neng)適(shi)用(yong),如屬雜質(zhi)(zhi)須先濾(lv)去。另外(wai),粘稠(chou)狀介(jie)(jie)質(zhi)(zhi)不(bu)能(neng)適(shi)用(yong),而(er)且,特定(ding)(ding)的產品適(shi)用(yong)的介(jie)(jie)質(zhi)(zhi)粘度范圍相對較窄(zhai)。 (5)型號(hao)多(duo)樣,用途廣泛(fan)(fan)。電(dian)(dian)磁閥(fa)雖有(you)先天不足(zu),優(you)點仍十分(fen)突出(chu),所(suo)以就(jiu)設計成多(duo)種多(duo)樣的(de)(de)產品,滿足(zu)各(ge)種不同的(de)(de)需求,用途極為廣泛(fan)(fan)。電(dian)(dian)磁閥(fa)技術的(de)(de)進步也都是圍(wei)繞著如何(he)克服先天不足(zu),如何(he)更好地發揮固有(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 |
