| 摘要 |
The invention relates to a valve which enables the adjustment of a flow of fluid between at least one inlet opening (13a) in the valve and at least one outlet opening (13b, 13c) of the valve, the outlet opening (13b, 13c) being completely or partially blockable by a blocking plug (17) rotatably mounted in a recess defined by an inner wall (16) of the valve, between an open position and a position in which the outlet opening (13b, 13c) is completely or partially blocked. The valve is characterised in that the valve also comprises a compression ring, said compression ring (18) being secured to said blocking plug (17) and free relative to said plug such that said compression ring (18) is arranged to match all or part of an edge (13b', 13c') of the outlet opening (13b, 13c) in the blocked position. The invention provides a seal in the blocked position but not in the open position. |
