The invention provides a vacuum gate valve for closing off an opening. The vacuum gate valve can have a valve plate that can be turned so that the alignment of the valve plate will adapt to a valve seat when the valve plate is pressed against the valve seat.Resilient Seated Gate Valves A vacuum gate valve comprising: a valve housing with a wall having an opening and a valve seat surrounding the opening; a valve plate in which a receptacle is formed and which has a sealing face for closing off the opening; a valve rod on which the valve plate is detachably mounted via a connecting segment of the valve rod engaging into the receptacle, Gate Valvesand which via control organs is supported and adjustable in such a way that by moving the valve plate over the opening by essentially following the valve rod axis and by pressing the sealing face of the valve plate against the valve seat the opening can be closed off,WATER POWER CONTROL VALVE where the receptacle and the connecting segment engaging into the receptacle comprise: a radial bearing segment making possible an at least partial turning of the valve plate relative to the valve rod about the valve rod axis, so that the alignment of the valve plate about the valve rod axis will adapt to the valve seat, at least when the valve plate is pressed for a first time onto the valve seat, and a segment confining the turning angle which confines the turning made possible by the radial bearing segment to a defined angular range, so that, while the valve plate is moved over the opening, no contact will occur between the valve housing and the valve plate due to an excessive turning angle; a first tapped hole arranged on the side of the connecting segment of the valve rod, essentially in the valve rod axis; a through bore in the valve plate along the valve rod axis between the receptacle and the side opposite to the receptacle; a screw passing through the through bore and engaging into the first tapped hole, so that the valve plate is fastened axially detachably along the valve rod axis to the valve rod, wherein the valve plate comprises at least one second tapped hole on the side opposite to the receptacle for receiving a multiple-function tool in order to manually apply a force to the valve plate, essentially along the valve rod axis, in particular for detaching the valve plate from the valve rod, and the screw is formed as a hexagon socket head screw having an associated wrench size with a width across corners smaller than the minor diameter of the second tapped hole of the valve plate; and the multiple-function tool for mounting and demounting the valve plate to and from the valve rod of the vacuum gate valve, said tool comprising: a handle, where the handle can apply a lifting force and a torque; and an elongated straight shaft, wherein the first end of the shaft is attached to the handle and wherein at the second end of the shaft at the tip an external hexagonal segment is formed for applying a torque to the hexagon socket head screw and in a segment adjacent to the external hexagon segment, an external thread is formed for making a screwed connection to the second tapped hole of the valve plate so as to apply a force to the valve plate along the valve rod axis, in particular in order to detach the valve plate from the valve rod, the width across corners of the external hexagonal segment being smaller than the minor diameter of the external thread.
