D71F凸耳式单夹蝶阀，蝶阀启闭件是一个圆盘形的蝶板，在阀体内绕其自身的轴线旋转，从而达到启闭或调节的阀门叫蝶阀。                                                                                                       蝶阀全开到全关通常是小于900，蝶阀和蝶杆本身没有自锁有力，为了蝶板的定位，要在阀杆上加装蜗轮减速器。采用蜗轮减速器，                                                                                             不仅可以使蝶板具有自锁能力，使蝶板停止在任意位置上，还能改善阀门的操作性能。工业专用蝶阀的特点能耐高温，                                                                                                                         适用压力范围也较高，阀门公称通径大，阀体采用碳钢制造，阀板的密封圈采用金属环代替橡胶环。                                                                                                                                                      大型高温蝶阀采用钢板焊接制造，主要用于高温介质的烟风道和煤气管道。                                                                                                                                                                                                 手柄蝶阀结构简单，性能优良，使用广泛。该产品可安装在石油、化工、食品、医药、轻纺、造纸、水电、船舶、城市给排水、                                                                                                         冶炼、能源等系统中一切腐蚀性、非腐蚀性的气体、液体、半流体、以及固体粉末管线和容器上作为调节和截流装置使用。
