Closing unit for a vacuum valve
First Claim
1. A closing unit for a vacuum valve comprising:
- a first valve plate for closing a first valve opening of the vacuum valve,a second valve plate for closing a second valve opening of the vacuum valve,a carrier plate that lies between the valve plates and to which the valve plates are fastened detachably, andat least one clamping piece by which interacting clamping surfaces are clamped to each other for fastening each of the valve plates to the carrier plate, at least one of the interacting clamping surfaces is constructed as an angular surface by which each of the valve plates is pressed onto the carrier plate,at least one clamping screw interacting with the clamping piece for clamping the clamping piece by exerting a clamping force onto the clamping piece, anda guide for each of the first and second valve plates, which is constructed between the respective valve plate and the carrier plate and by which the valve plate is guided along a guide path,wherein for joining the respective valve plate with the carrier plate, the valve plate is inserted in the guide and moved relative to the carrier plate along the guide path up to an end position in which the interacting clamping surfaces of the carrier plate and the valve plate, which are distanced before reaching the end position and approach each other when moving the valve plate along the guide path towards the end position, come into mutual engagement and wherein the guide secures the valve plate against lifting from the carrier plate.

Abstract
A closing unit for a vacuum valve includes a first valve plate (7) for closing a first valve opening (2) of the vacuum valve, a second valve plate (8) for closing a second valve opening (3) of the vacuum valve, and a carrier plate (19) that lies between the valve plates (7, 8) to which the valve plates (7, 8) are fastened detachably. For fastening a corresponding valve plate (7, 8) to the carrier plate (19), at least one clamping piece (20, 21) is used by which interacting clamping surfaces (22-26) are clamped with each other. Of the interacting clamping surfaces (22-26), at least one is constructed as an angular surface by which the corresponding valve plate (7, 8) is pressed against the carrier plate (19).

10. A vacuum valve comprising:
-
a valve housing with a first valve opening that is surrounded by a first valve seat and a second valve opening that is surrounded by a second valve seat, and a closing unit arranged in the valve housing, the closing unit comprising a first valve plate for closing the first valve opening of the valve housing, a second valve plate for closing the second valve opening of the valve housing, a carrier plate that lies between the valve plates and to which the valve plates are fastened detachably, and at least one clamping piece by which interacting clamping surfaces are clamped with each other for fastening a corresponding valve plate to the carrier plate, at least one of the interacting clamping surfaces is constructed as an angular surface by which the corresponding valve plate is pressed against the carrier plate, at least one clamping screw interacting with the clamping piece for clamping the clamping piece by exerting a clamping force onto the clamping piece, and a guide for each of the first and second valve plates, which is constructed between the respective valve plate and the carrier plate and by which the valve plate is guided along a guide path, wherein for joining the respective valve plate with the carrier plate, the valve plate is inserted in the guide and moved relative to the carrier plate along the guide path up to an end position in which the interacting clamping surfaces of the carrier plate and the valve plate, which are distanced before reaching the end position and approach each other when moving the valve plate along the guide path towards the end position, come into mutual engagement and wherein the guide secures the valve plate against lifting from the carrier plate. - View Dependent Claims (11, 13, 15, 16)

12. A valve plate for fastening to a carrier plate of a closing unit comprising
at least one clamping surface constructed as an angular surface by which the valve plate can be pressed against the carrier plate by a clamping of the valve plate with the carrier plate by at least one clamping piece, a groove or a projection arranged on a side of the valve plate intended to face the carrier plate in the mounted state of the valve plate, the groove or projection having undercut side walls which form guide surfaces defining a guide path for guiding the valve plate relative to the carrier plate when joining the valve plate and the carrier plate, wherein the guide path stands at an angle to a direction of a longitudinal extent of the clamping surface formed as an angular surface.
