An integrated Valve to a distribution network that includes Fluid Fluid, a locking Piece, a Hollow Body, a Bearing Device around a Stump, the Stump to immobilize a Fluid; Distribution Network; Installation; and a method for partial dismantling Valve.

摘要

This valve (2) is integrated into a fluid distribution network and enables selective interruption or authorization of the circulation of a fluid; it includes a fluid blocking member driven in rotation by an actuator device of the valve and at least one journal (20), a hollow body (24) inside which the blocking member (22) is mobile and which defines at least one bore (A26) for receiving the journal (20), and a bearing (31) disposed around each journal (20) and inside the bore (A26) of the body (24) enabling support of the journal (20) and guidance thereof in rotation relative to the bore (A26), thereby centering the journal (20). The valve (2) further includes a device (30) for immobilizing and sealing for maintenance the journal relative to the body (22) of the valve (2), this immobilization device (30) being on the same side of the bearing (31) as the internal volume (V24) of the hollow body (24) and being maneuverable via the bearing (31) to go from a non-clamped first configuration to a clamped second configuration in which it immobilizes the journal (20) in the bore (A26) and vice versa.
