氣動低溫球閥產品概述

氣動低溫球閥由適(shi)用(yong)(yong)(yong)(yong)(yong)于介(jie)質溫度(du)-196℃~-40℃的(de)(de)(de)(de)(de)(de)浮動(dong)(dong)球或固定(ding)球球閥(fa)與氣動(dong)(dong)執行(xing)機構組成，通過(guo)氣缸活塞(sai)角行(xing)程(cheng)控(kong)制(zhi)閥(fa)門(men)的(de)(de)(de)(de)(de)(de)啟閉(bi)，其氣動(dong)(dong)執行(xing)器的(de)(de)(de)(de)(de)(de)輸(shu)出(chu)端與閥(fa)桿的(de)(de)(de)(de)(de)(de)上端之(zhi)間經連(lian)接(jie)(jie)軸傳動(dong)(dong)聯接(jie)(jie)，利(li)用(yong)(yong)(yong)(yong)(yong)有(you)(you)壓氣體作為動(dong)(dong)力(li)源，推動(dong)(dong)活塞(sai)移動(dong)(dong)，從而通過(guo)輸(shu)出(chu)軸驅動(dong)(dong)閥(fa)桿帶動(dong)(dong)球體旋轉，實現閥(fa)門(men)的(de)(de)(de)(de)(de)(de)開啟和關(guan)閉(bi)動(dong)(dong)作。該(gai)閥(fa)填料根據(ju)使(shi)用(yong)(yong)(yong)(yong)(yong)溫度(du)可(ke)采用(yong)(yong)(yong)(yong)(yong)PTFE、柔性石墨(mo)、唇形密封(feng)圈等(deng)多重組合的(de)(de)(de)(de)(de)(de)型式，有(you)(you)很好(hao)的(de)(de)(de)(de)(de)(de)耐低(di)溫性能，而且(qie)中法蘭密封(feng)選(xuan)用(yong)(yong)(yong)(yong)(yong)具有(you)(you)抵(di)抗溫度(du)交變、高回彈特(te)性的(de)(de)(de)(de)(de)(de)金(jin)屬(shu)纏繞柔性石墨(mo)墊(dian)片、金(jin)屬(shu)環(huan)墊(dian)。本產品(pin)氣缸通常與行(xing)程(cheng)限位開關(guan)、電磁(ci)閥(fa)、空氣過(guo)濾減壓閥(fa)等(deng)附件配套使(shi)用(yong)(yong)(yong)(yong)(yong)，接(jie)(jie)入0.4 ~ 0.7MPa氣源即(ji)可(ke)控(kong)制(zhi)運(yun)轉，因此(ci)特(te)適(shi)合安裝在液化(hua)天然氣、液態乙烯(xi)、液氧、液氫等(deng)不適(shi)宜人工(gong)手(shou)動(dong)(dong)操作的(de)(de)(de)(de)(de)(de)低(di)溫介(jie)質管(guan)道上，作遠距(ju)離和自動(dong)(dong)化(hua)控(kong)制(zhi)。
