<p>1. Device for securing a valve to a fluid conduit, at the extremity of a conduit or between two conduits, each conduit extremity being integral with an annular flange, the valve comprising a peripheral side surface (27) and two end faces (43, 44) characterized in that : - the device comprises flange portions (31) with their inner surfaces (33) adapted to fit on the peripheral side surface (27) of the valve outside its working areas ; - the peripheral valve side surface (27) and the inward surface (33) of the flange portions comprise corresponding engaging portions (30, 33) able to fit one within the other in such a way that when the flange portion is thrust against the circumferential valve side surface, the engaging parts limit the relative axial displacement of the valve with respect to the flange portion ; - the set of these flange portions comprises axial projections (32) provided with bores which are aligned with corresponding bores of the annular flange or flanges once the flange portions have been placed in contact against the peripheral valve side surface (27), with the corresponding engaging parts fitted into one another.</p> |
