New type of Ultrahigh Vacuum Gate valve are ultra think type gate valves developed based on original valve, are applicable for ultrahigh vacuum. Exteranl surface of valve adopts silver grey matte finishing. It looks high grade. Main parts and components such valve boday and plate are made of 304 stainless steel with very low air bleeding amount, and drive component which realizes movement of valve body adopts 316L stainless steel welded bellows. Imported fluorine rubber gasket with very low air bleeding amount is used for sealing of valve plate. If baking is required, please refer to the Performance index. So that it prevents the valve from being damaged or reliability of valve seal from being affected.
The valve utilizes screw (manual and electric) or cylinder rod (pneumatic) drive to push (pull) link mechanism under the axial movement of seal shaft, thus to drive valve spool assembly to do axial movement. When stop block on the valve spool assembly moves to the end, seal plate and support plate will stop axial movement, at this point, seal plate and support plate will be concentric with lateral flange hole, if continue to push the valve spool assembly, the steel ball which lies in the steel ball groove of seal plate and support plate will be gradually pushed out, thus to make seal plate and support be split off by the steel ball, and respectively press against sealing surface and supporting surface of flange, when the steel ball completely leaves the groove and is located at the plane of seal plate and support plate, it will reach maximum pressing force, the valve will be fully closed, and under the action of fluorine rubber sealing ring, it plays a desired sealing effect; when the valve spool assembly is pulled to move backwards, due to very large friction between seal plate and support plate and flange surfaces, the steel ball will be firstly pulled back to the steel ball groove of seal plate and support plate, under the action of spring, seal plate and support leave the sealing surface and supporting surface of flange and press the steel ball into the steel ball groove, and the whole valve spool assembly moves backward under the drive of link mechanism, leaves the flange orifice and make the valve be fully opened.
1. High reliability
2. Good tightness and ultra-low air bleeding rate
3. Stable motion, small noise and vibration
4. Easy installation and compact structure
5. Elegant appearance
The series ultrahigh vacuum gate valve is one of the important elements of Ultrahigh vacuum system, which can be used as a switching mechanism of ultrahigh vacuum line.
The series ultrahigh vacuum gate valve is applicable for the occasions with air and non- corrosive gas as working media.
