意大利ATOS溢流閥主要特點外(wai)漏堵絕,內漏易控,使用安(an)全。 內(nei)外(wai)泄漏(lou)(lou)是危及安全的要素。其它自控(kong)閥(fa)通常(chang)將閥(fa)桿伸出,由電(dian)(dian)動(dong)(dong)、氣動(dong)(dong)、液動(dong)(dong)執(zhi)行(xing)機構控(kong)制閥(fa)芯的轉動(dong)(dong)或(huo)移動(dong)(dong)。這都要解決長(chang)期(qi)動(dong)(dong)作閥(fa)桿動(dong)(dong)密(mi)封(feng)的外(wai)泄漏(lou)(lou)難題;唯有(you)(you)電(dian)(dian)磁閥(fa)是用電(dian)(dian)磁力(li)作用于(yu)密(mi)封(feng)在電(dian)(dian)動(dong)(dong)調(diao)節(jie)閥(fa)隔磁套管(guan)內(nei)的鐵芯完成(cheng),不存在動(dong)(dong)密(mi)封(feng),所以(yi)外(wai)漏(lou)(lou)易堵絕。電(dian)(dian)動(dong)(dong)閥(fa)力(li)矩(ju)控(kong)制不易,容易產生內(nei)漏(lou)(lou),甚至(zhi)拉斷(duan)閥(fa)桿頭部(bu);電(dian)(dian)磁閥(fa)的結構型式容易控(kong)制內(nei)泄漏(lou)(lou),直至(zhi)降為零。所以(yi),電(dian)(dian)磁閥(fa)使用特別安全,尤其適(shi)用于(yu)腐蝕性(xing)、有(you)(you)毒或(huo)高低溫(wen)的介質。 意大利ATOS溢流閥系統簡單,便接電腦,價格低謙。 溢流閥本身結構(gou)簡單,價(jia)格也低,比起調節閥等其(qi)它(ta)種類執行器易于安(an)裝維護(hu)。更(geng)(geng)顯著的(de)(de)是(shi)所組成的(de)(de)自(zi)控(kong)系統簡單得多,價(jia)格要(yao)低得多。由于電磁閥是(shi)開(kai)關(guan)信(xin)號控(kong)制,與工控(kong)計算(suan)機連接十分方便(bian)。在當(dang)今(jin)電腦普及(ji),價(jia)格大(da)幅(fu)下降的(de)(de)時代,電磁閥的(de)(de)優勢(shi)就(jiu)更(geng)(geng)加明顯。 意大利ATOS溢流閥動作快遞,功率微小,外形輕巧。 電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)響應時間可以短(duan)至(zhi)幾(ji)個(ge)(ge)毫秒(miao),即使是先導式(shi)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)也可以控制在幾(ji)十毫秒(miao)內(nei)。由于(yu)自(zi)成(cheng)回路,比之(zhi)其它自(zi)控閥(fa)反應更(geng)靈敏。設計得當的電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)線圈功(gong)率消(xiao)耗(hao)很低,屬(shu)節(jie)(jie)(jie)能(neng)(neng)(neng)產品;還可做到只(zhi)需觸發動作,自(zi)動保持閥(fa)位,平時一點也不(bu)耗(hao)電(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)外形尺寸小,既(ji)節(jie)(jie)(jie)省空間,又輕巧美(mei)觀。電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)調(diao)節(jie)(jie)(jie)精度受限(xian),適用(yong)介質(zhi)受限(xian)。電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)通常只(zhi)有(you)開關兩(liang)種狀態(tai),閥(fa)芯(xin)只(zhi)能(neng)(neng)(neng)處于(yu)兩(liang)個(ge)(ge)極限(xian)位置(zhi),不(bu)能(neng)(neng)(neng)連續調(diao)節(jie)(jie)(jie),(力圖突(tu)破(po)的新構(gou)思不(bu)少,但還都處于(yu)試驗試用(yong)階(jie)段(duan))所以調(diao)節(jie)(jie)(jie)精度還受到一定限(xian)制。 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。 另外,粘稠狀介(jie)質不(bu)能適(shi)用,而且,特定的(de)產(chan)(chan)品(pin)適(shi)用的(de)介(jie)質粘度范圍相對(dui)較(jiao)窄。意大利ATOS溢流閥(fa)型(xing)號(hao)多(duo)樣,用途(tu)廣泛。電磁閥(fa)雖(sui)有先天不(bu)足,優點仍十分(fen)突出,所以(yi)就設計成(cheng)多(duo)種多(duo)樣的(de)產(chan)(chan)品(pin),滿足各種不(bu)同的(de)需求,用途(tu)極為廣泛。電磁閥(fa)技(ji)術的(de)進步也都是(shi)圍繞著(zhu)如何(he)克服先天不(bu)足,如何(he)更(geng)好地發揮(hui)固有優勢而展開。 意大利ATOS溢流閥原裝* AGMZA-A-10/250/M AGMZA-A-10/250/PA-M AGMZA-A-20/250/M AGMZO-A-10/100 AGMZO-A-10/100/Y 20 AGMZO-A-10/210 AGMZO-A-10/210/18 AGMZO-A-10/210/E AGMZO-A-10/210/Y AGMZO-A-10/315 AGMZO-A-10/315/E 20 AGMZO-A-10/315/Y AGMZO-A-20/210 AGMZO-A-20/315 AGMZO-A-20/315/Y AGMZO-A-32/315 AGMZO-AE-10/210 10 AGMZO-AE-10/315 10 AGMZO-AE-20/315/Y 10 AGMZO-AE-32/315 AGMZO-TER-010/210/I AGMZO-TER-10/100/I AGMZO-TER-10/210 AGMZO-TER-10/315/Y 40 AGMZO-TER-20/210 AGMZO-TER-20/315/Y 40 |
