意大利ATOS比例閥DHZO-TE-071-L5 ATOS比(bi)例(li)(li)換向(xiang)閥(fa)(fa)(fa)屬于比(bi)例(li)(li)閥(fa)(fa)(fa)的(de)(de)一(yi)種，用來(lai)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)流(liu)量(liang)(liang)(liang)(liang)(liang)和(he)流(liu)向(xiang)。ATOS比(bi)例(li)(li)閥(fa)(fa)(fa)對流(liu)量(liang)(liang)(liang)(liang)(liang)的(de)(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)可以分為兩種：一(yi)種是(shi)開關(guan)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi):要(yao)(yao)(yao)么(me)全開、要(yao)(yao)(yao)么(me)全關(guan)，流(liu)量(liang)(liang)(liang)(liang)(liang)要(yao)(yao)(yao)么(me)zui大、要(yao)(yao)(yao)么(me)zui小，沒有(you)中間狀(zhuang)態，如(ru)(ru)普(pu)通(tong)的(de)(de)電(dian)磁直通(tong)閥(fa)(fa)(fa)、電(dian)磁換向(xiang)閥(fa)(fa)(fa)、電(dian)液換向(xiang)閥(fa)(fa)(fa)。另一(yi)種是(shi)連(lian)續控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)：閥(fa)(fa)(fa)口可以根(gen)據需要(yao)(yao)(yao)打(da)開任(ren)意一(yi)個開度，由此控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)通(tong)過流(liu)量(liang)(liang)(liang)(liang)(liang)的(de)(de)大小，這類閥(fa)(fa)(fa)有(you)手動(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)的(de)(de)，如(ru)(ru)節流(liu)閥(fa)(fa)(fa)，也有(you)電(dian)控(kong)(kong)(kong)(kong)(kong)的(de)(de)，如(ru)(ru)比(bi)例(li)(li)閥(fa)(fa)(fa)、伺服(fu)閥(fa)(fa)(fa)。所以使用比(bi)例(li)(li)閥(fa)(fa)(fa)或伺服(fu)閥(fa)(fa)(fa)的(de)(de)目的(de)(de)就是(shi):以電(dian)控(kong)(kong)(kong)(kong)(kong)方式實現對流(liu)量(liang)(liang)(liang)(liang)(liang)的(de)(de)節流(liu)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(當然經(jing)過結構上(shang)的(de)(de)改動(dong)也可實現壓力控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)等)，既然是(shi)節流(liu)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)，就必(bi)然有(you)能量(liang)(liang)(liang)(liang)(liang)損失，伺服(fu)閥(fa)(fa)(fa)和(he)其(qi)它(ta)閥(fa)(fa)(fa)不同的(de)(de)是(shi)，它(ta)的(de)(de)能量(liang)(liang)(liang)(liang)(liang)損失更大一(yi)些(xie)，因為它(ta)需要(yao)(yao)(yao)一(yi)定的(de)(de)流(liu)量(liang)(liang)(liang)(liang)(liang)來(lai)維持(chi)前(qian)置(zhi)級(ji)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)油路的(de)(de)工作。 電(dian)氣比(bi)(bi)(bi)例閥(fa)自(zi)動控(kong)(kong)(kong)(kong)制(zhi)(zhi)可分成斷(duan)續控(kong)(kong)(kong)(kong)制(zhi)(zhi)和連續控(kong)(kong)(kong)(kong)制(zhi)(zhi)。斷(duan)續控(kong)(kong)(kong)(kong)制(zhi)(zhi)即開關控(kong)(kong)(kong)(kong)制(zhi)(zhi)。氣動控(kong)(kong)(kong)(kong)制(zhi)(zhi)系統中使用動作頻率較低(di)的(de)開關式(ON-OFF)的(de)換(huan)向(xiang)閥(fa)來(lai)(lai)控(kong)(kong)(kong)(kong)制(zhi)(zhi)氣路的(de)通斷(duan)。靠減(jian)壓(ya)閥(fa)來(lai)(lai)調節(jie)所(suo)需(xu)要(yao)的(de)壓(ya)力(li)，靠節(jie)流閥(fa)來(lai)(lai)調節(jie)所(suo)需(xu)要(yao)的(de)流量。這種傳統的(de)氣動控(kong)(kong)(kong)(kong)制(zhi)(zhi)系統要(yao)想要(yao)有多個(ge)輸(shu)(shu)出力(li)和多個(ge)運動速度，就(jiu)需(xu)要(yao)多個(ge)減(jian)壓(ya)閥(fa)、節(jie)流閥(fa)及換(huan)向(xiang)閥(fa)。這樣(yang)，不僅元(yuan)件(jian)需(xu)要(yao)多，成本高(gao)，構成系統復雜(za)，且許(xu)多元(yuan)件(jian)都需(xu)要(yao)預先進行人工調節(jie)。電(dian)氣比(bi)(bi)(bi)例閥(fa)控(kong)(kong)(kong)(kong)制(zhi)(zhi)屬于連續控(kong)(kong)(kong)(kong)制(zhi)(zhi)，其特(te)點是輸(shu)(shu)出量隨輸(shu)(shu)入量的(de)變化而(er)變化，輸(shu)(shu)出量與(yu)輸(shu)(shu)入量之(zhi)間存(cun)在(zai)一(yi)定的(de)比(bi)(bi)(bi)例關系。比(bi)(bi)(bi)例控(kong)(kong)(kong)(kong)制(zhi)(zhi)有開環控(kong)(kong)(kong)(kong)制(zhi)(zhi)和閉環控(kong)(kong)(kong)(kong)制(zhi)(zhi)之(zhi)分。 意大利阿托斯比例閥DHZO-TE-071-L5 ATOS比例閥現貨型號：
