D71F凸耳式單夾蝶閥，蝶閥啟閉件是一個圓盤形的蝶板，在閥體內繞其自身的軸線旋轉，從而達到啟閉或調節的閥門叫蝶閥。 蝶閥全開到全關通常是小于900，蝶閥和蝶桿本身沒有自鎖有力，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。工業專用蝶閥的特點能耐高溫， 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代替橡膠環。 大型高溫蝶閥采用鋼板焊接制造，主要用于高溫介質的煙風道和煤氣管道。 手柄蝶閥結構簡單，性能優良，使用廣泛。該產品可安裝在石油、化工、食品、醫藥、輕紡、造紙、水電、船舶、城市給排水、 冶煉、能源等系統中一切腐蝕性、非腐蝕性的氣體、液體、半流體、以及固體粉末管線和容器上作為調節和截流裝置使用。
