<p>1. A device (7) for the horizontal monitoring of a flow of fluid for use in conduits of hydraulic installations conveying gases and liquids, more particularly radioactive or other contaminated gases and liquids, in a closed circuit, the said device comprising a body having a cylindrical sleeve (15) inserted in the conduit (4) in which the device is mounted, a door valve (13) being mounted inside the said sleeve (15) and pivoting with its upper portion about a horizontal axis (20) transverse to the said sleeve (15), the said device being characterised in that : a) it comprises an internal space defined by the intersection between the said sleeve (15) and a cylinder (18) having the same inner diameter as the sleeve (15), the axis of the cylinder being perpendicular to that of the sleeve (15), b) the pivoting space of the said door valve (13) is delimited by the inner cylindrical surface (16) of the said sleeve (15) and by the inner cylindrical surface (17) of the said cylinder (18), c) the door valve (13) has a dimension parallel to the said horizontal axis (20) greater than the said inner diameter and is provided at its upper portion with a cut-out (22) which allows a flow of liquid to act upon the lower part of the door valve (13) without impeding the passage of one of the said gases through the said cut-out (22).</p> |
