Disc valve

摘要

A multiway control valve is provided having a housing that has an inlet connection and an outlet connection for a liquid and/or gaseous medium, a rotatably mounted ceramic valve disc, which is arranged with a first through-flow opening and rotatably mounted in the housing to fluidically connect and disconnect from each other the connections depending on its rotational position. The valve disc rests flatly on a ceramic sealing disc, arranged in a torque-proof manner and having two second through-flow openings, and a sealing element, which is arranged between the sealing disc and an intermediate floor of the housing and is elastically deformable. The sealing element has a disc shape and has third through-flow openings that are aligned with the second through-flow openings. The intermediate floor has at least one retaining projection that engages in one of the three through-flow openings for positively locking anti-twist protection of the sealing element.

1. A disc valve comprising:
a housing comprising connections for a liquid medium or a gaseous medium or both including at least one inlet connection and at least one outlet connection; at least one sealing disc arranged in a torque-proof manner and having at least two second through-flow openings; at least one rotatably mounted valve disc rotatably mounted in the housing to fluidically connect and disconnect the connections depending on its rotational position and comprising at least one first through-flow opening, wherein the at least one rotatably mounted valve disc rests flatly on the at least one sealing disc, and a sealing element that is elastically deformable and arranged between the at least one sealing disc and an intermediate floor of the housing, wherein the sealing element is configured in a disc shape and has third through-flow openings that are aligned with the second through-flow openings, wherein the intermediate floor comprises a retaining projection that engages in one of the third through-flow openings for positively locking anti-twist protection of the sealing element, wherein the anti-twist protection has at least one axial projection that is arranged off-center on the intermediate floor and that extends through a breakthrough of the sealing element at least fundamentally in a positively locking manner and is inserted at least in some areas into a receiving recess of the sealing disc for its anti-twist protection.
