  • Patent number: 8272112
    Abstract: The invention particularly relates to a tool set making it possible to introduce in a sheath (2) a flow-monitoring device (1) comprising a hollow body (11), a valve (12), a cup-type seal member (13), and a plurality of retention elastic legs (14). This tool set comprises three tools (3, 4, 5), whereof the first tool is formed of a contention bushing (31) and an ejecting pusher (32), whereof the third tool (5) receives the sheath (2) and comprises a cylinder (51) wherein a centering piston (51) slides in the sheath, and whereof the second tool (4) shaped like a funnel, is inserted between the first tool (3) and the third tool (5), and makes it possible to radially compress the seal (13) and the legs (14) of the device (1) while inserting them into the sheath (2) while this device is pushed out of the first tool.

  • Patent number: 8028573
    Abstract: The invention particularly relates to a tool set for setting-up a flow monitoring device (1) in a fluid piping (K). This tool set comprises at least one hollow semi-flexible hose (31) provided with a jack (33) bearing the device (1) in a sheath, a pump (32) monitoring the pressure inside the hose, a support member (4) slidingly crossed by the hose (31), and an introduction airlock (5) carried by the support member and making it possible to sealingly insert the hose in the piping (K).

  • Patent number: 6962165
    Abstract: A safety device for insertion into a pipeline (K) in which fluid circulates in an upstream (X?) and a downstream (X+) direction, comprises a tube (1) that provides the fluid with a central circulatory passage (CC) regulated by a central valve (3) that closes in the event of an excessive flow of this fluid. There is an annular valve closure member (4) which is elastically malleable, mounted to the external periphery of the tube (1), and provides the fluid with a peripheral circulatory passage which it selectively obstructs by subjecting a radial expansion in the event of an excessive flow of fluid.

  • Publication number: 20040103943
    Abstract: A safety device for insertion into a pipeline (K) in which fluid circulates in an upstream (X−) and a downstream (X−) direction, comprises a tube (1) that provides the fluid with a central circulatory passage (CC) regulated by a central valve (3) that closes in the event of an excessive flow of this fluid. There is an annular valve closure member (4) which is elastically malleable, mounted to the external periphery of the tube (1), and provides the fluid with a peripheral circulatory passage which it selectively obstructs by subjecting a radial expansion in the event of an excessive flow of fluid.

  • Patent number: 6328072
    Abstract: A safety device for protecting a fluid pipeline (1) from an excessive flow of the fluid running through it. The device includes a body (2) delimited by a tubular wall (20), having an upstream end (21) and a downstream end (22) and being selectively inserted into the pipeline (1). A valve (3), which is sensitive to a pressure loss, is supported by the body (2) and disposed between the upstream and downstream ends. A retaining means (4a, 4b) holds the body (2) in place inside the pipeline (1). An inflatable envelope (5) is provided outside the body for impermeably encasing a section of effective length of the tubular wall (20) into which at least one first opening (231) is cut.
