Patent

CA 2595492

An apparatus for controlling the flow of a medium. The apparatus comprises a base having a plurality of arms extending from the base. The base and arms define a cage. A valve member is positioned within the cage. The apparatus further includes a biasing housing disposed within the base, and wherein a spring is disposed within the biasing housing. The apparatus further includes a passageway formed about the valve member when the valve member is opened so that the medium flows on the outer portion of the biasing housing, and wherein the flow of the medium in an opposite direction urges the ball into engagement with the valve seat. When the valve is open, the medium collapses the spring and the valve member blocks the flow of the medium from entering the biasing housing. A method of drilling a well with the flow valve positioned on a work string is also disclosed.

L'invention concerne un appareil servant à réguler l'écoulement d'un milieu. Cet appareil comprend une base pourvue d'une pluralité de bras s'étendant à partir de cette base. La base et les bras définissent une cage. Un élément vanne est disposé à l'intérieur de la cage. L'appareil selon l'invention comprend également un logement de sollicitation disposé dans la base, un ressort étant disposé à l'intérieur du logement de sollicitation. L'appareil comprend encore un passage formé autour de l'élément vanne lorsque ledit élément est ouvert, de sorte que le milieu s'écoule sur la partie extérieure du logement de sollicitation, l'écoulement du milieu dans une direction opposée sollicitant la bille en contact avec le siège de vanne. Lorsque la vanne est ouverte, le milieu affaisse le ressort et l'élément vanne empêche l'écoulement du milieu de pénétrer dans le logement de sollicitation. L'invention concerne également un procédé de forage d'un puits comprenant une vanne de régulation placée sur un train de tiges.
