ATOS比例閥：錐(zhui)(zhui)(zhui)(zhui)閥(fa)(fa)的(de)(de)左端設(she)有偏流(liu)(liu)(liu)(liu)盤(pan)1托(tuo)住彈(dan)壓(ya)彈(dan)簧，錐(zhui)(zhui)(zhui)(zhui)閥(fa)(fa)右端有一阻尼(ni)(ni)活塞(阻尼(ni)(ni)活塞一方(fang)面在錐(zhui)(zhui)(zhui)(zhui)閥(fa)(fa)開(kai)(kai)(kai)(kai)啟或閉合時起阻尼(ni)(ni)作(zuo)(zuo)(zuo)用，用來提高錐(zhui)(zhui)(zhui)(zhui)閥(fa)(fa)工作(zuo)(zuo)(zuo)的(de)(de)穩定性；另一方(fang)面用來保證錐(zhui)(zhui)(zhui)(zhui)閥(fa)(fa)開(kai)(kai)(kai)(kai)啟后不會傾(qing)斜)。進口的(de)(de)壓(ya)力油(壓(ya)力為P)可(ke)以(yi)由此活塞的(de)(de)徑向間隙進入活塞底部，形成一個向左的(de)(de)液(ye)(ye)(ye)壓(ya)力F=P·A(A為活塞底部面積(ji))。當作(zuo)(zuo)(zuo)用在底部的(de)(de)液(ye)(ye)(ye)壓(ya)力F大于彈(dan)簧力時，錐(zhui)(zhui)(zhui)(zhui)閥(fa)(fa)閥(fa)(fa)口打(da)(da)開(kai)(kai)(kai)(kai)，油液(ye)(ye)(ye)由錐(zhui)(zhui)(zhui)(zhui)閥(fa)(fa)口經回流(liu)(liu)(liu)(liu)口溢(yi)(yi)回油箱。只要(yao)閥(fa)(fa)口打(da)(da)開(kai)(kai)(kai)(kai)，有油液(ye)(ye)(ye)流(liu)(liu)(liu)(liu)經溢(yi)(yi)流(liu)(liu)(liu)(liu)閥(fa)(fa)，ATOS溢(yi)(yi)流(liu)(liu)(liu)(liu)閥(fa)(fa)入口的(de)(de)壓(ya)力就(jiu)基本保持恒定。通過調節(jie)桿4來改變調壓(ya)彈(dan)簧的(de)(de)預緊力Ft，即可(ke)調整溢(yi)(yi)流(liu)(liu)(liu)(liu)壓(ya)力。 ATOS比例閥動(dong)作快遞，功率微小(xiao)，外(wai)形輕巧。電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)響應時(shi)間可(ke)以(yi)短(duan)至幾(ji)個毫(hao)秒(miao)，即使是先(xian)(xian)導(dao)式電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)也(ye)可(ke)以(yi)控(kong)(kong)制(zhi)在幾(ji)十毫(hao)秒(miao)內(nei)。由(you)于(yu)(yu)自(zi)成(cheng)回路(lu)，比(bi)之(zhi)其它自(zi)控(kong)(kong)閥(fa)(fa)(fa)反應更靈敏。設計得當(dang)的電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)線圈功率消(xiao)耗很低，屬(shu)節能(neng)產品(pin)；還(huan)可(ke)做到只(zhi)需觸發動(dong)作，自(zi)動(dong)保持閥(fa)(fa)(fa)位，平時(shi)一點(dian)(dian)也(ye)不耗電(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)外(wai)形尺寸(cun)小(xiao)，既節省(sheng)空間，又輕巧美觀。電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)調節精度(du)受限，適用(yong)(yong)介(jie)質(zhi)受限。電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)通常只(zhi)有開關兩種狀(zhuang)態，閥(fa)(fa)(fa)芯只(zhi)能(neng)處(chu)(chu)于(yu)(yu)兩個極限位置，不能(neng)連續調節，(力圖突破的新構思不少(shao)，但還(huan)都處(chu)(chu)于(yu)(yu)試驗試用(yong)(yong)階(jie)段)所以(yi)調節精度(du)還(huan)受到一定限制(zhi)。ATOS溢(yi)(yi)流(liu)閥(fa)(fa)(fa)對(dui)介(jie)質(zhi)潔(jie)凈度(du)有較(jiao)高要求，含顆粒(li)狀(zhuang)的介(jie)質(zhi)不能(neng)適用(yong)(yong)，如屬(shu)雜質(zhi)須先(xian)(xian)濾(lv)去。另外(wai)，粘(zhan)稠狀(zhuang)介(jie)質(zhi)不能(neng)適用(yong)(yong)，而(er)且(qie)，特定的產品(pin)適用(yong)(yong)的介(jie)質(zhi)粘(zhan)度(du)范圍(wei)相對(dui)較(jiao)窄。意大利ATOS溢(yi)(yi)流(liu)閥(fa)(fa)(fa)型號多(duo)樣，用(yong)(yong)途廣泛。電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)雖有先(xian)(xian)天(tian)不足，優點(dian)(dian)仍十分突出，所以(yi)就設計成(cheng)多(duo)種多(duo)樣的產品(pin)，滿(man)足各種不同的需求，用(yong)(yong)途極為廣泛。電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)技術的進步也(ye)都是圍(wei)繞著如何克服先(xian)(xian)天(tian)不足，如何更好(hao)地發揮固有優勢而(er)展(zhan)開。 AGMZO系列 HMP-013/210/V
