  • Automatically-actuated safety device with a double-seated valve to regulate the flow rate of a fluid
    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.

  • Automatically-actuated safety device with a double-seated valve to regulate the flow rate of a 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.
