Abstract
The invention relates to a check valve for blocking a fluid-carrying line in case of reversal of the flow direction, containing a valve housing defining a flow path and having two connecting pieces and a valve seat therebetween, and a flap module mounted in the valve housing and containing a shut-off body interacting with the valve seat, a bearing device for pivotably supporting the shut-off body such that the latter is movable between an open position and a closed position, and a lever extending between the shut-off body and the bearing device and being connected to the shut-off body and the bearing device. For easier manufacturing, the invention proposes that a part of the flap module is formed by at least one sheet-metal shaped part.
Claims19
Check valve for automatically blocking a fluid-carrying line in the event of a reversal of the flow direction, containing
- a valve housing, which defines a flow path and has two connecting pieces and a valve seat disposed therebetween, and
- a flap module, which is mounted in the valve housing and contains a shut-off body that interacts with the valve seat, a bearing device for pivotably supporting the shut-off body in the valve housing in such a way that the shut-off body is movable between an open position, in which the flow path is cleared, and a closed position, in which the shut-off body lies sealingly against the valve seat, and a lever, which extends between the shut-off body and the bearing device and is connected to the shut-off body and the bearing device,
- wherein at least one part of the flap module is formed by a sheet-metal shaped part,
- wherein the shut-off body comprises a detent element and the lever comprises a recess, the recess being used to latch with the detent element, such that the lever is connected by a detent connection detachably to the shut-off body, and
- wherein the shut-off body and the detent element are made in one part.
