Title
(EN) LOW PRESSURE-LOSS VALVE FOR ROD-OPERATED SUBSURFACE PUMP
(FR) SOUPAPE À FAIBLE PERTE DE PRESSION POUR POMPE SOUTERRAINE ACTIONNÉE PAR UNE TIGE
Abstract
(EN)
A valve assembly (100) that provides for reduced pressure loss in a downhole positive displacement pump comprises: a cylindrical body (110) comprising a cage, with the cage having an upper end (112), a lower end (114) and a tubular side wall (111) forming an axial bore; a ball (115) residing within the cage; two or more ball guides (113) configured to keep the ball generally along a centerline of the cage; a cone (116) concentrically residing within the cage above a position where the ball stops in an open position; a ball stop (117) residing within the cage and preventing the ball from rising to an upper end of the cone when the ball moves to an open position; and a seat (118) residing below the cage, wherein the seat sealingly receives the ball when the ball falls to the bottom of the cage, but permits fluids to flow through the seat and around the ball when the ball floats off the seat and into its open position.
(FR)
L'invention concerne un ensemble soupape (100) qui assure une perte de pression réduite dans une pompe volumétrique de fond de trou et qui comprend : un corps cylindrique (110) comprenant une cage, la cage ayant une extrémité supérieure (112), une extrémité inférieure (114) et une paroi latérale tubulaire (111) formant un alésage axial; une bille (115) située à l'intérieur de la cage; deux ou plusieurs guides de billes (113) configurés pour maintenir la bille généralement le long d'une ligne centrale de la cage; un cône (116) résidant concentriquement à l'intérieur de la cage au-dessus d'une position dans laquelle la bille s'arrête dans une position ouverte; une butée à bille (117) se trouvant à l'intérieur de la cage et empêchant la bille de monter jusqu'à une extrémité supérieure du cône lorsque la bille se déplace vers une position ouverte; et un siège (118) se trouvant sous la cage, le siège recevant de manière étanche la bille lorsque la bille tombe au fond de la cage, mais permettant aux fluides de s'écouler à travers le siège et autour de la bille lorsque la bille flotte hors du siège et dans sa position ouverte.
