科恩科knke电动高真空插板阀,electric high vacuum gate valve,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。
电动高真空插板阀适用的工作介质为洁净的空气及非腐蚀性气体。
electric ultra-high vacuum gate valve uses electric device to drive the stem, moving valve disc up and down to make the valve opened or closed. it is used to put through or cut off the airflow in vacuum pipeline. applicable medium can be pure air and noncorrosive gases. with signal feedback device.
