Example Embodiment

[0033] in Figure 1 to 14 A first embodiment of the vacuum valve according to the present invention is shown in FIG.

[0034] The vacuum valve has a valve housing 1 with an inner chamber 2 in which a plate-shaped closing body 3 in this embodiment is arranged.

[0035] In the closed state of the vacuum valve shown in the drawing, the valve hole 4 of the valve housing is closed by the closing body 3, and the valve hole has an axis 5. To this end, the closing body 3 is pressed against the valve seat 6 surrounding the valve hole 4. In the described embodiment, an elastic seal 7 is provided on the closing body 6 and abuts against the sealing surface of the valve seat 6. In the modified embodiment, the seal can also be arranged on the valve seat 6 and the sealing surface is arranged on the closing body 3.

[0036] In the closed state of the vacuum valve, the closing body 3 occupies the closed position shown in the drawing.

[0037] In the open state of the vacuum valve, the valve hole 4 i...

Abstract

The valve has a closure element (3) that is arranged in an interior (2) of a valve housing (1). The closure element surrounding a valve opening (4) is mounted in a valve seat (6) in a closed state.The valve housing has a housing wall (19) made of sheet metal, for delimiting the interior. A flange ring (21) is connected to a connection flange (28) of a vacuum unit (27) by a screw connection. The interior of the vacuum unit is attached to the valve housing.The closure element is placed over the valve seat in the closed state by the flange ring.

Description

technical field [0001] The invention relates to a vacuum valve, comprising a closing body and a valve casing, the valve casing has a valve hole and an inner chamber, the closing body is arranged in the inner chamber, and the closing body leans against a valve seat surrounding the valve hole in the closed state of the vacuum valve above, wherein the valve housing has a housing wall made of thin plates delimiting an inner chamber, which housing wall is provided with a window gap for constituting the valve opening, and wherein the valve opening is surrounded by a flange ring which can be bolted The connection is connected to a connection flange of a vacuum unit with an inner chamber, to which a vacuum valve can be connected. Background technique [0002] It is known in vacuum valves to form the housing wall from thin plates, thereby saving material. Vacuum valves of the above-mentioned type are given by WO 2011 / 088482 A1 and US 7,011,294 B1. The vacuum valve has housing halve...
