Title (EN) FLEXIBLE SEAT BALL VALVE
(FR) SOUPAPE À BILLE À SIÈGE FLEXIBLE
Abstract: front page image
(EN) A system includes a ball valve. The ball valve includes a housing (15), a ball (20), and a first valve seat assembly. The housing (15) includes a chamber, a first fluid passage (28) intersecting the chamber, and a second fluid passage (30) intersecting the chamber. The ball (20) is disposed in the chamber and is configured to control fluid flow between the first and second fluid passages. The first valve seat assembly is disposed between the ball (20)n and the housing (15). The first valve seat assembly includes a first seat (40) configured to seat against the ball (20) both above and below a pressure threshold, and a second seat (42) configured to seat against the ball (20) only above the pressure threshold, wherein the second seat (42) has a coefficient of friction that is lower than the first seat (40).
(FR) [0035] L'invention concerne un système comprend une soupape à bille. La soupape à bille comprend un boîtier (15), une bille (20) et un premier ensemble siège de soupape Le boîtier (15) comprend une chambre, un premier passage de fluide (28) coupant la chambre, et un second passage de fluide (30) coupant la chambre. La bille (20) est disposée dans la chambre et est configurée pour réguler l'écoulement de fluide entre les premier et second passages de fluide. Le premier ensemble siège de soupape est disposé entre la bille (20) et le boîtier (15). Le premier ensemble siège de soupape comprend un premier siège (40) configuré pour s'appuyer contre la bille (20) au-dessus et au-dessous d'un seuil de pression, et un second siège (42) configuré pour s'appuyer contre la bille (20) uniquement au-dessus du seuil de pression, le second siège (42) ayant un coefficient de frottement inférieur à celui du premier siège (40).
