DHI電磁換向閥的特點(dian): (1)外(wai)漏(lou)(lou)堵(du)絕(jue),內漏(lou)(lou)易控(kong),使用安全(quan)(quan)。內外(wai)泄漏(lou)(lou)是(shi)危及安全(quan)(quan)的(de)(de)(de)要素。其(qi)它自控(kong)閥(fa)通常將閥(fa)桿(gan)(gan)伸出(chu),由電(dian)(dian)動(dong)、氣動(dong)、液動(dong)執行機構控(kong)制閥(fa)芯的(de)(de)(de)轉(zhuan)動(dong)或移動(dong)。這(zhe)都(dou)要解決長期(qi)動(dong)作閥(fa)桿(gan)(gan)動(dong)密(mi)(mi)封(feng)的(de)(de)(de)外(wai)泄漏(lou)(lou)難(nan)題;唯(wei)有電(dian)(dian)磁閥(fa)是(shi)用電(dian)(dian)磁力作用于密(mi)(mi)封(feng)在(zai)電(dian)(dian)動(dong)調節閥(fa)隔磁套管內的(de)(de)(de)鐵芯完(wan)成,不存在(zai)動(dong)密(mi)(mi)封(feng),所以外(wai)漏(lou)(lou)易堵(du)絕(jue)。電(dian)(dian)動(dong)閥(fa)力矩控(kong)制不易,容易產生內漏(lou)(lou),甚至拉斷閥(fa)桿(gan)(gan)頭部;電(dian)(dian)磁閥(fa)的(de)(de)(de)結構型(xing)式容易控(kong)制內泄漏(lou)(lou),直至降為零。所以,電(dian)(dian)磁閥(fa)使用特別安全(quan)(quan),尤其(qi)適(shi)用于腐蝕(shi)性、有毒或高(gao)低溫(wen)的(de)(de)(de)介質。 (2)系(xi)統簡(jian)單,便接(jie)電(dian)腦,價(jia)格低謙。電(dian)磁閥本身結(jie)構簡(jian)單,價(jia)格也低,比(bi)起(qi)調節閥等其它種類執行器(qi)易于安裝維護。更顯(xian)(xian)著的(de)(de)是所組(zu)成的(de)(de)自控系(xi)統簡(jian)單得多,價(jia)格要低得多。由于電(dian)磁閥是開關(guan)信號(hao)控制,與工控計算機(ji)連接(jie)十分方便。在當今電(dian)腦普及(ji),價(jia)格大幅(fu)下降的(de)(de)時代,電(dian)磁閥的(de)(de)優勢就更加明顯(xian)(xian)。 (3)動作(zuo)快(kuai)遞,功(gong)率微小,外(wai)形(xing)輕巧。電(dian)(dian)磁(ci)閥(fa)(fa)(fa)響應時間可以(yi)短(duan)至幾(ji)個(ge)毫(hao)秒,即使(shi)是先導式電(dian)(dian)磁(ci)閥(fa)(fa)(fa)也可以(yi)控(kong)制在幾(ji)十毫(hao)秒內。由于自(zi)成回路,比之其它自(zi)控(kong)閥(fa)(fa)(fa)反應更靈(ling)敏。設計(ji)得當的電(dian)(dian)磁(ci)閥(fa)(fa)(fa)線(xian)圈功(gong)率消耗很低,屬節(jie)能產(chan)品;還可做到只需觸發(fa)動作(zuo),自(zi)動保(bao)持閥(fa)(fa)(fa)位,平時一點也不耗電(dian)(dian)。電(dian)(dian)磁(ci)閥(fa)(fa)(fa)外(wai)形(xing)尺寸(cun)小,既節(jie)省空間,又輕巧美(mei)觀。 (4)調(diao)節(jie)(jie)精(jing)度受限(xian),適(shi)用(yong)介質(zhi)受限(xian)。電(dian)磁閥(fa)通常只有開關兩(liang)種狀態(tai),閥(fa)芯只能(neng)處(chu)于兩(liang)個(ge)極限(xian)位置,不能(neng)連續調(diao)節(jie)(jie),(力圖突破的(de)新構思不少(shao),但還(huan)都處(chu)于試(shi)驗試(shi)用(yong)階(jie)段)所以調(diao)節(jie)(jie)精(jing)度還(huan)受到一定(ding)(ding)限(xian)制。電(dian)磁閥(fa)對介質(zhi)潔凈度有較高要求,含顆(ke)粒狀的(de)介質(zhi)不能(neng)適(shi)用(yong),如(ru)屬雜質(zhi)須先濾去。另外,粘稠狀介質(zhi)不能(neng)適(shi)用(yong),而且,特定(ding)(ding)的(de)產(chan)品適(shi)用(yong)的(de)介質(zhi)粘度范圍相對較窄。 (5)型號多樣,用途廣泛。電(dian)磁(ci)閥雖有(you)(you)先天不(bu)足(zu),優(you)點仍(reng)十分突出,所以就設計成(cheng)多種(zhong)多樣的產品,滿足(zu)各種(zhong)不(bu)同的需求(qiu),用途極為廣泛。電(dian)磁(ci)閥技術的進步也都是圍繞著如何克(ke)服先天不(bu)足(zu),如何更好地發揮固有(you)(you)優(you)勢而展開。 DHI電磁換向閥系列型號(hao): 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 |
