A butterfly valve includes an annular, elastic sealing element that encloses an axial opening, a valve disk which is disposed inside the axial opening so as to be rotatable transversal to the axial direction, a device for rotating the valve disk between closed and open positions in order to control a fluid flow through the opening, and at least two valve housing parts that enclose the sealing element in an annular manner and embrace two flanges which are connected to an inlet and an outlet. Conical contact areas of the flanges and/or the valve housing parts cooperate in such a way that the flanges are axially pressed in a sealing fashion against the sealing element by means of the valve housing parts in the operationally mounted state. The flanges are respectively connected in a rigid and positive manner to a couple of clamps.

The invention claimed is: 1. Throttle flap valve having an essentially ring-shaped, elastic seal element (4) that surrounds an axial opening, having a valve disk (6) disposed to rotate in the axial opening, crosswise to the axial direction, having means for turning the valve disk (6) between the open and the closed positions, to control a flow of fluid through the opening, having at least two valve housing parts (5) configured as two clamp halves (5) that essentially surround the seal element (4) in ring shape, which surround two flanges (3) connected with an inflow (1) and an outflow (2), the clamp halves having inner surfaces in contact with the seal element (4) comprising two ring-shaped depressions (10) surrounding the flanges (3), in each instance, wherein the depressions (10) are raised higher than the portion of the clamp halves in contact with the seal element (4), whereby conical contact surfaces of the flanges (3) and/or the valve housing parts (5) work together in such a manner that the flanges (3) are pressed axially against the seal element (4), forming a seal, by means of the valve housing parts (5), in the assembled state ready for operation, wherein the flanges (3) are rigidly connected with the valve housing parts (5), forming a positive lock, in each instance, and wherein the flanges (3) are shaped to have rotation symmetry. 2. Throttle flap valve according to claim 1, wherein the depressions (10) are beveled at the edges (11). 3. Throttle flap valve according to claim 1, wherein each flange is configured to narrow conically towards the outside. 4. Throttle flap valve according to claim 1, wherein the valve housing parts (5) are configured so that they can be connected with screws (13) and nuts (14). 5. Throttle flap valve according to claim 1, wherein the valve housing parts (5) are configured with two ring-shaped recesses (8) that lie radially opposite one another, for accommodating valve disk shafts (7) of the valve disk (6). 6. Throttle flap valve according to claim 1, wherein the means for turning the valve disk (6) is a hand wheel. 7. Throttle flap valve according to claim 1, wherein the means for turning the valve disk (6) is an automatic setting element. 8. Method for assembling a throttle flap valve according to claim 1, wherein in a first step, the seal element (4) is set onto the valve disk (6), wherein in a second step, sleeves (9) are set onto valve disk shafts (7) of the valve disk (6), wherein in a third step, the valve disk (6) provided with the seal element (4) and the sleeves (9) is placed between the flanges (3), wherein in a fourth step, the valve housing parts (5) are placed around the flanges (3), wherein in a fifth step, the valve disk shafts (7) of the valve disk (6) are oriented in a desired angle orientation, wherein in a sixth step, the adjustable means (13, 14) for applying contracting radial and axial forces to the sealing element (4) are adjusted until the flanges (3) are rigidly connected with the clamp halves (5), forming a positive lock, and wherein in a last step, the means for turning the valve disk (6) are affixed.
