氣動低溫球閥產品概述

氣動低溫球閥由適(shi)用(yong)(yong)于(yu)介質溫(wen)(wen)度(du)-196℃~-40℃的(de)浮動(dong)(dong)球(qiu)(qiu)或固定球(qiu)(qiu)球(qiu)(qiu)閥與(yu)(yu)氣(qi)(qi)動(dong)(dong)執行(xing)機構組成，通(tong)過氣(qi)(qi)缸(gang)活塞(sai)角行(xing)程(cheng)控(kong)(kong)制(zhi)閥門的(de)啟(qi)閉，其氣(qi)(qi)動(dong)(dong)執行(xing)器(qi)的(de)輸出端與(yu)(yu)閥桿(gan)的(de)上端之(zhi)間經連(lian)接(jie)軸(zhou)傳動(dong)(dong)聯接(jie)，利用(yong)(yong)有壓(ya)(ya)氣(qi)(qi)體(ti)作為動(dong)(dong)力源，推動(dong)(dong)活塞(sai)移(yi)動(dong)(dong)，從而通(tong)過輸出軸(zhou)驅動(dong)(dong)閥桿(gan)帶(dai)動(dong)(dong)球(qiu)(qiu)體(ti)旋(xuan)轉，實現(xian)閥門的(de)開(kai)啟(qi)和關(guan)閉動(dong)(dong)作。該閥填料(liao)根據使用(yong)(yong)溫(wen)(wen)度(du)可采(cai)用(yong)(yong)PTFE、柔(rou)性石墨、唇形密封(feng)圈等(deng)(deng)多(duo)重組合(he)的(de)型(xing)式，有很好的(de)耐低(di)溫(wen)(wen)性能，而且(qie)中法(fa)蘭密封(feng)選用(yong)(yong)具有抵(di)抗(kang)溫(wen)(wen)度(du)交變、高回彈特(te)性的(de)金(jin)(jin)屬纏繞柔(rou)性石墨墊片、金(jin)(jin)屬環墊。本產品(pin)氣(qi)(qi)缸(gang)通(tong)常與(yu)(yu)行(xing)程(cheng)限位開(kai)關(guan)、電磁閥、空(kong)氣(qi)(qi)過濾減壓(ya)(ya)閥等(deng)(deng)附件配套使用(yong)(yong)，接(jie)入0.4 ~ 0.7MPa氣(qi)(qi)源即可控(kong)(kong)制(zhi)運(yun)轉，因此(ci)特(te)適(shi)合(he)安裝在液(ye)化天然(ran)氣(qi)(qi)、液(ye)態乙烯、液(ye)氧、液(ye)氫(qing)等(deng)(deng)不適(shi)宜人工手動(dong)(dong)操作的(de)低(di)溫(wen)(wen)介質管道上，作遠距離(li)和自(zi)動(dong)(dong)化控(kong)(kong)制(zhi)。
