GIQ氣動(dòng)高真空蝶閥是指關(guān)閉件(閥瓣或蝶板)為圓盤,圍繞閥軸旋轉(zhuǎn)來達(dá)到開啟與關(guān)閉的一種閥,在管道上主要起切斷和節(jié)流用。蝶閥啟閉件是一個(gè)圓盤形的蝶板,在閥體內(nèi)繞其自身的軸線旋轉(zhuǎn),從而達(dá)到啟閉或調(diào)節(jié)的目的。蝶閥全開到全關(guān)通常是小于90° ,蝶閥和蝶桿本身沒有自鎖能力,為了蝶板的定位,要在閥桿上加裝蝸輪減速器。采用蝸輪減速器,不僅可以使蝶板具有自鎖能力,使蝶板停止在任意位置上,還能改善閥門的操作性能。工業(yè)蝶閥的特點(diǎn)能耐高溫,適用壓力范圍也較高,閥門公稱通徑大,閥體采用碳鋼制造,閥板的密封圈采用金屬環(huán)代替橡膠環(huán)。大型高溫蝶閥采用鋼板焊接制造,主要用于高溫介質(zhì)的煙風(fēng)道和煤氣管道。
