Abstract
A valve arrangement has an annular housing with valve seat and a two-part valve plate that is rotatable about an axis. The seat is in the form of a disk including two adjacent openings with a web between and the axis is parallel to the web. The two parts of the valve plate are next to each other with their planes parallel and offset in a perpendicular direction. They are connected to each other through one of the openings by a connection piece extending through the one opening. In a closed position for the valve, the valve plate part are respectively positioned on opposite sides of the valve seat and cover and seal the respective openings due to a seal that is between the valve plate parts and the valve seat.
Claims12
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.
