意大利ATOS電磁換向閥的特點: (1)外漏堵絕(jue),內(nei)漏易控(kong)(kong),使用安(an)(an)全(quan)(quan)。內(nei)外泄(xie)漏是危及安(an)(an)全(quan)(quan)的要素。其它自(zi)控(kong)(kong)閥(fa)(fa)通常將閥(fa)(fa)桿(gan)伸出,由電(dian)(dian)(dian)動、氣動、液動執行機構控(kong)(kong)制(zhi)閥(fa)(fa)芯(xin)的轉動或(huo)(huo)移動。這都要解決長(chang)期動作(zuo)閥(fa)(fa)桿(gan)動密(mi)封的外泄(xie)漏難(nan)題;唯有電(dian)(dian)(dian)磁(ci)閥(fa)(fa)是用電(dian)(dian)(dian)磁(ci)力作(zuo)用于密(mi)封在(zai)(zai)電(dian)(dian)(dian)動調節(jie)閥(fa)(fa)隔磁(ci)套管內(nei)的鐵芯(xin)完(wan)成,不存在(zai)(zai)動密(mi)封,所以(yi)外漏易堵絕(jue)。電(dian)(dian)(dian)動閥(fa)(fa)力矩控(kong)(kong)制(zhi)不易,容易產生內(nei)漏,甚至(zhi)拉斷閥(fa)(fa)桿(gan)頭部;電(dian)(dian)(dian)磁(ci)閥(fa)(fa)的結構型式(shi)容易控(kong)(kong)制(zhi)內(nei)泄(xie)漏,直至(zhi)降為零。所以(yi),電(dian)(dian)(dian)磁(ci)閥(fa)(fa)使用特別安(an)(an)全(quan)(quan),尤其適(shi)用于腐蝕性、有毒或(huo)(huo)高低溫的介質。 (2)系統(tong)簡單(dan)(dan),便(bian)接(jie)電(dian)腦(nao),價(jia)格(ge)低(di)謙。電(dian)磁閥(fa)(fa)本(ben)身結構簡單(dan)(dan),價(jia)格(ge)也(ye)低(di),比起調節(jie)閥(fa)(fa)等其它種類執行器易(yi)于安裝維護。更顯(xian)著(zhu)的是所組成的自控(kong)(kong)系統(tong)簡單(dan)(dan)得(de)多(duo),價(jia)格(ge)要低(di)得(de)多(duo)。由于電(dian)磁閥(fa)(fa)是開關信號控(kong)(kong)制,與(yu)工(gong)控(kong)(kong)計算機(ji)連接(jie)十分(fen)方便(bian)。在當(dang)今電(dian)腦(nao)普(pu)及,價(jia)格(ge)大(da)幅下降的時代,電(dian)磁閥(fa)(fa)的優(you)勢就更加明顯(xian)。 (3)動作快(kuai)遞,功率微小,外形(xing)輕巧。電(dian)磁(ci)(ci)閥響應(ying)時間(jian)可(ke)以(yi)短至幾個(ge)毫(hao)秒,即(ji)使是先導(dao)式(shi)電(dian)磁(ci)(ci)閥也可(ke)以(yi)控制在幾十毫(hao)秒內。由于(yu)自(zi)成回路,比之其它自(zi)控閥反(fan)應(ying)更靈敏。設計得當的電(dian)磁(ci)(ci)閥線圈功率消耗很低,屬節(jie)能產品;還(huan)可(ke)做到只需(xu)觸(chu)發動作,自(zi)動保持閥位,平時一點也不耗電(dian)。電(dian)磁(ci)(ci)閥外形(xing)尺(chi)寸(cun)小,既節(jie)省(sheng)空間(jian),又輕巧美(mei)觀。 (4)調(diao)節精(jing)度受限(xian),適(shi)用介質(zhi)(zhi)(zhi)(zhi)受限(xian)。電磁閥(fa)通常(chang)只有開(kai)關兩種狀態,閥(fa)芯只能(neng)(neng)處(chu)于兩個極(ji)限(xian)位置,不(bu)(bu)能(neng)(neng)連續調(diao)節,(力圖(tu)突破的(de)新構思不(bu)(bu)少,但還都處(chu)于試驗試用階段)所以調(diao)節精(jing)度還受到一定限(xian)制。電磁閥(fa)對(dui)介質(zhi)(zhi)(zhi)(zhi)潔凈度有較(jiao)(jiao)高要求(qiu),含顆粒狀的(de)介質(zhi)(zhi)(zhi)(zhi)不(bu)(bu)能(neng)(neng)適(shi)用,如屬(shu)雜質(zhi)(zhi)(zhi)(zhi)須(xu)先濾(lv)去。另外,粘稠狀介質(zhi)(zhi)(zhi)(zhi)不(bu)(bu)能(neng)(neng)適(shi)用,而且,特定的(de)產(chan)品適(shi)用的(de)介質(zhi)(zhi)(zhi)(zhi)粘度范圍相對(dui)較(jiao)(jiao)窄。 (5)型號多樣,用(yong)途廣泛(fan)。電磁閥雖有先(xian)天不(bu)足,優點(dian)仍十分突出,所以就(jiu)設計成多種多樣的產品(pin),滿足各種不(bu)同的需求,用(yong)途極(ji)為廣泛(fan)。電磁閥技(ji)術的進步也都(dou)是(shi)圍繞著(zhu)如(ru)何克服先(xian)天不(bu)足,如(ru)何更好地發揮固有優勢而(er)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 |
