Abstract
The invention relates to a vacuum valve for gas-tight sealing of a flow path, comprising at least one thrust rod, which has a cylindrical connecting section, and a closure plate which is removably mounted on the thrust rod and has at least one concave, semicircular first rod recess corresponding to the connecting section. A clamping piece, which has a concave, semicircular second rod recess corresponding to the connecting section, is adjustably mounted by means of a mechanical fixing element on the closure plate in such a way that the semicircular first rod recess and the opposite semicircular second rod recess define a cylindrical holding region which is adjustable in width and in which the cylindrical connecting section is detachably held.
