The CCD series electric ultra-high vacuum plug-in valve uses the screw to electrically push the sealing shaft (rod) to move axially and push (pull) the lifting mechanism to drive the driving body to move axially. When the positioning plate moves to the stop block, the sealing The pressure plate and the support plate stop moving axially, and the steel ball lying in the ball socket of the sealing pressure plate and the support plate is pushed out of the ball socket by the driving body, so that the support plate and the sealing pressure plate are away from the driving body and pressed against the supporting surface of the valve flange And the sealing surface, when the steel ball completely leaves the ball socket and is on the plane of the support plate and the sealing pressure plate, the pressing force reaches the maximum, and the valve is completely closed. When the driving body is pulled to move backward, due to the sealing pressure plate and the support plate The friction between the flange surface and the flange surface is very large, the steel ball is pulled back to the ball socket by the driving body, the sealing pressure plate and the support plate are pressed to the driving body under the action of the central spring, and move backward together with the driving body to leave the flange orifice , so that the valve is fully open. The applicable working medium is clean air and non-corrosive gas.

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。
