DDC-JQ


Electric high vacuum butterfly valve

CCD型系列电动超高真空插板阀是利用螺杆电动推动密封轴(杆)做轴向运动推(拉)动举升机构带动驱动体沿轴向运动当定位板运动到止动块时,密封压板和支撑板停止轴向移动,而卧在密封压板和支撑板球窝内的钢球被驱动体推出球窝,从而使支撑板和密封压板背离驱动体,而压向阀门法兰的支撑面和密封面,当钢球完全离开球窝而位于支撑板和密封压板的平面上时,压紧力达到最大,阀门被完全关闭,当驱动体被拉动向后运动时,由于密封压板和支撑板与法兰面间摩擦力很大,钢球被驱动体拉回球窝,密封压板和支撑板在中心弹簧的作用下,压向驱动体,随驱动体一同向后运动,离开法兰孔口,使阀门完全打开。 适用的工作介质为洁净的空气及非腐蚀性气体。
