Title
(EN) VALVE WITH PRESSURE DIFFERRENTIAL SEATING
(FR) SOUPAPE À SIÈGE À DIFFÉRENTIEL DE PRESSION
Abstract
(EN)
A valve for use in oil and gas production or similar applications includes a plug or other flow barrier disposed in a cavity of a hollow valve body with a metal-to-metal sealing surface that is not reliant on any rubberized or elastomeric material to effect a seal. The figures and art described herein show that this novel feature can increase the ability of the valve to seal in high-pressure environments, and also increase the reliability of the valve when in cycling use.
(FR)
La présente invention concerne une soupape destinée à être utilisée dans la production de pétrole et de gaz ou d'autres applications similaires et comprenant un obturateur ou une autre barrière d'écoulement disposée dans une cavité d'un corps de soupape creux avec une surface d'étanchéité métal-métal qui n'est pas basée sur un quelconque matériau caoutchouté ou élastomère pour réaliser un joint d'étanchéité. Les figures et l'aspect technique décrits ici montrent que ce nouvel élément peut augmenter la capacité de la soupape à se sceller dans des environnements à haute pression, et augmenter également la fiabilité de la soupape lors de l'utilisation en cyclage.
