Patent

CA 2514842

The present invention provides an apparatus and method for controlling the flow of fluids through a conveyance (20) with a hydraulic valve including a flexible portion (10). The flexible portion is positioned in the conveyance so that fluid enters the flexible portion from an upper containment space (40) and the expansion of the flexible portion causes the valve to restrict or block the flow of fluid being controlled through the conveyance. A float- operated mechanical make-up valve (70) is provided to automatically maintain a desired fluid level in the containment space.

L'invention concerne un appareil et un procédé de régulation d'écoulement de fluides dans un élément de transport qui comprend une vanne hydraulique présentant une partie flexible. La partie flexible est positionnée dans l'élément de transport de façon que le fluide pénètre dans une membrane depuis un espace de contention supérieur et que l'expansion de ladite partie flexible amène la vanne à limiter ou à bloquer l'écoulement de fluide régulé dans ledit élément de transport.
