意大利ATOS溢流閥主要特點外漏堵絕(jue)，內漏易控，使用安全(quan)。 內外(wai)泄漏(lou)是(shi)危及安全的(de)要素。其(qi)(qi)它自控(kong)閥(fa)通常將(jiang)閥(fa)桿伸出，由電(dian)(dian)動(dong)(dong)(dong)(dong)、氣動(dong)(dong)(dong)(dong)、液(ye)動(dong)(dong)(dong)(dong)執行機構(gou)控(kong)制(zhi)閥(fa)芯的(de)轉動(dong)(dong)(dong)(dong)或移動(dong)(dong)(dong)(dong)。這都要解決長(chang)期動(dong)(dong)(dong)(dong)作閥(fa)桿動(dong)(dong)(dong)(dong)密(mi)封的(de)外(wai)泄漏(lou)難題；唯(wei)有(you)電(dian)(dian)磁(ci)(ci)閥(fa)是(shi)用電(dian)(dian)磁(ci)(ci)力(li)作用于密(mi)封在電(dian)(dian)動(dong)(dong)(dong)(dong)調節閥(fa)隔磁(ci)(ci)套管內的(de)鐵芯完成，不存在動(dong)(dong)(dong)(dong)密(mi)封，所(suo)以外(wai)漏(lou)易(yi)(yi)(yi)堵絕。電(dian)(dian)動(dong)(dong)(dong)(dong)閥(fa)力(li)矩(ju)控(kong)制(zhi)不易(yi)(yi)(yi)，容易(yi)(yi)(yi)產生內漏(lou)，甚至(zhi)拉斷(duan)閥(fa)桿頭部；電(dian)(dian)磁(ci)(ci)閥(fa)的(de)結構(gou)型式容易(yi)(yi)(yi)控(kong)制(zhi)內泄漏(lou)，直至(zhi)降為零(ling)。所(suo)以，電(dian)(dian)磁(ci)(ci)閥(fa)使用特別安全，尤其(qi)(qi)適用于腐蝕性、有(you)毒(du)或高低溫(wen)的(de)介質。 意大利ATOS溢流閥系統簡單，便接電腦，價格低謙。 溢(yi)流(liu)閥(fa)(fa)本身結構(gou)簡(jian)單，價格(ge)也低，比起(qi)調節閥(fa)(fa)等其它種類執行器(qi)易于(yu)安(an)裝維護。更(geng)顯(xian)(xian)著的是(shi)(shi)所組(zu)成的自(zi)控(kong)系統(tong)簡(jian)單得多，價格(ge)要低得多。由于(yu)電(dian)磁閥(fa)(fa)是(shi)(shi)開(kai)關信號控(kong)制，與工控(kong)計(ji)算機連接十(shi)分方便(bian)。在當今電(dian)腦普及，價格(ge)大(da)幅下降的時代，電(dian)磁閥(fa)(fa)的優勢就更(geng)加明顯(xian)(xian)。 意大利ATOS溢流閥動作快遞，功率微小，外形輕巧。 電(dian)(dian)磁閥(fa)響應時(shi)間(jian)可以短至幾(ji)(ji)個毫秒，即使(shi)是先(xian)導(dao)式電(dian)(dian)磁閥(fa)也可以控(kong)制(zhi)(zhi)在幾(ji)(ji)十毫秒內。由(you)于自(zi)成回(hui)路，比之(zhi)其它自(zi)控(kong)閥(fa)反(fan)應更靈敏。設計得當的(de)電(dian)(dian)磁閥(fa)線圈功率(lv)消耗(hao)很低(di)，屬節(jie)能產品；還(huan)可做到只需觸發(fa)動(dong)作(zuo)，自(zi)動(dong)保持閥(fa)位，平時(shi)一點也不(bu)耗(hao)電(dian)(dian)。電(dian)(dian)磁閥(fa)外形尺寸小，既節(jie)省空(kong)間(jian)，又輕(qing)巧美觀。電(dian)(dian)磁閥(fa)調節(jie)精度(du)受限，適用(yong)(yong)介質受限。電(dian)(dian)磁閥(fa)通常只有(you)開關兩種狀態，閥(fa)芯只能處于兩個極限位置，不(bu)能連(lian)續調節(jie)，(力(li)圖突(tu)破的(de)新構思不(bu)少，但還(huan)都(dou)處于試(shi)驗試(shi)用(yong)(yong)階段)所以調節(jie)精度(du)還(huan)受到一定(ding)限制(zhi)(zhi)。 ATOS溢流閥對介質潔凈度有較高要求，含顆粒狀的介質不能適用，如屬雜質須先濾去。 另(ling)外，粘稠狀(zhuang)介(jie)質不(bu)能適用(yong)，而(er)且，特定的(de)(de)產(chan)品(pin)適用(yong)的(de)(de)介(jie)質粘度范圍(wei)(wei)相對較窄。意大利ATOS溢(yi)流閥型號多(duo)(duo)樣(yang)，用(yong)途廣(guang)泛。電(dian)(dian)磁閥雖有(you)先天不(bu)足(zu)，優點(dian)仍(reng)十分突出，所以(yi)就設計(ji)成多(duo)(duo)種多(duo)(duo)樣(yang)的(de)(de)產(chan)品(pin)，滿足(zu)各種不(bu)同的(de)(de)需求，用(yong)途極(ji)為廣(guang)泛。電(dian)(dian)磁閥技術的(de)(de)進步也都是圍(wei)(wei)繞(rao)著如(ru)何(he)(he)克服先天不(bu)足(zu)，如(ru)何(he)(he)更好地發揮(hui)固(gu)有(you)優勢而(er)展開(kai)。 意大利ATOS溢流閥原裝* AGMZA-A-10/250/M
