Abstract
A valve housing for a vacuum valve has opposed valve openings (8, 9), which have axes (10, 11) and are surrounded by flanges (6, 7) of the valve housing, these flanges being connected to housing parts (1, 2) of the valve housing. A respective flange (6, 7) has, or is formed on the whole by, a sheet metal part (12, 13) formed in a U-shaped manner, as viewed in a longitudinal center section through the flange (6, 7), parallel to the axis (10, 11) of the valve opening (8, 9), and directed via its open side toward the housing part (1, 2). The U-shaped sheet metal part (12, 13) includes inner and outer branches (14, 15) annularly surrounding the axis (10, 11) of the valve opening (8, 9) and a base crosspiece (16) connecting the inner and the outer branch (14, 15).
