VALVE DEVICE, USE OF SUCH A VALVE DEVICE AND ASSOCIATED SEALING DEVICE |
| 摘要 |
A valve device, in particular, in the form of a ball valve (1), having a blocking element (3) movably guided in a valve housing (2), which may be brought via a fluid passage (6) by means of an actuating device (4) from a pass-through position connecting at least two connecting points (5) to one another in the valve housing (2) into a blocking position, which interrupts this connection, and vice versa, and having a sealing device having at least one sealing ring which, together with its central opening, comprises the fluid passage (6) and which seals it along at least one sealing gap, is characterized in that the ring profile of at least one sealing ring of the sealing device has a ring opening that interrupts this profile in such a way that the sealing ring changes from an initial shape to an installation shape differing therefrom, in which it seals the sealing gap that can be assigned thereto with a predefinable pretension having an increased sealing force effect. |

1. A valve device, in particular, in the form of a ball valve (1), having a blocking element (3) movably guided in a valve housing (2), which may be brought, via a fluid passage (6), by means of an actuating device (4) from a pass-through position, connecting at least two connecting points (5) to one another in the valve housing (2), into a blocking position, which interrupts this connection, and vice versa, and having a sealing device having at least one sealing ring which, together with its central opening (27), comprises the fluid passage (6) and which seals it along at least one sealing gap (28), characterized in that that the ring profile of at least one sealing ring (26) of the sealing device has a ring opening (29) that interrupts this profile in such a way that the sealing ring (26) changes from an initial shape to an installation shape differing from the former, in which it seals the sealing gap (28) that can be assigned thereto with a predefinable pretension having an increased sealing force effect. |
