Abstract:
1. A valve arrangement for pipe lines or containers, comprising: an annular housing part ( 11 , 11 ′) encompassing a line cross section having a parting plane; a valve plate ( 12 , 12 ′) having at least one shaft part ( 13 , 13 ′) supported on the housing part ( 11 ) on both sides of the valve plate and being rotatable about a rotational axis ( 10 ) that is transverse to the housing part between an open and a closed position; a valve seat ( 17 ) on the housing part ( 11 , 11 ′); a seal ( 15 , 16 ) between the valve seat ( 17 ) and the valve plate ( 12 , 12 ′) for forming a sealing between the valve seat and the valve plate in the closed position; the valve seat ( 17 ) comprising a disk disposed within and transversely across the housing part in the parting plane, the valve seat disk ( 17 ) including two adjacent openings ( 20 , 21 ) with a web between the openings, the rotational axis ( 10 ) being disposed parallel to the web; the valve plate ( 12 , 12 ′) comprising a two-part plate having first and second valve plate parts ( 12 , 12 ′) disposed next to one another, the valve plate parts lying in parallel planes with respect to one another that are offset from each other in a direction perpendicularly to the parallel planes, the first valve plate part ( 12 ) being fixedly connected to the second valve plate part ( 12 ′) by connection means ( 14 ) for connecting the valve plate parts to each other through one of the openings ( 20 , 21 ) such that in the closed position the first valve plate part ( 12 ) is positioned on one side of the valve seat disk ( 17 ) to cover one of the openings ( 20 ) and the second valve plate ( 12 ′) is positioned on an opposite side of the valve seat disk ( 17 ) to cover the other opening ( 21 ); the seal comprising two seals ( 15 , 16 ), one seal extending around the one opening ( 20 ) and the other seal extending around the other opening ( 21 ), the seals being between the valve seat disk ( 17 ) and the respective valve plate parts ( 12 , 12 ′) on both sides of the valve seat disk ( 17 ) for sealing the two openings in the closed position.
