Title (EN) ROTARY CONTROL VALVE HAVING A CLAMPED VALVE SEAT
(FR) VANNE DE RÉGULATION ROTATIVE PRÉSENTANT UN SIÈGE DE VANNE SERRÉ
Abstract:
(EN) A rotary valve (100) is provided for use in highly corrosive and abrasive applications. The valve includes a valve body (104) and an adapter (108) coupled to one end of the valve body, thereby defining an inlet (124), an outlet (164), and a valve interior (132) in fluid communication with the inlet and the outlet. The valve also includes a floating ball element (212) pivotably mounted in the valve interior via a valve stem (216) to control fluid flow through the valve, a first valve seat (200) movably disposed in the valve interior, and a second valve seat (204) removably disposed in the valve interior. The first valve seat is biased toward the ball element to sealingly engage a first portion of the ball element. The second valve seat is configured to sealingly engage a second portion of the ball element and is clamped between a surface of the valve body and a surface of the adapter.
(FR) L'invention concerne une vanne rotative (100) utilisable dans des applications hautement corrosives et abrasives. La vanne comprend un corps de vanne (104) et un adaptateur (108) couplé à une extrémité du corps de vanne, délimitant ainsi une entrée (124), une sortie (164) et un intérieur de vanne (132) en communication fluidique avec l'entrée et la sortie. La vanne comprend également: un élément bille flottante (212) monté pivotant à l'intérieur de la vanne par le biais d'une tige de vanne (216) pour réguler l'écoulement de fluide à travers la vanne; un premier siège de vanne (200) disposé mobile à l'intérieur de la vanne; et un second siège de vanne (204) disposé amovible à l'intérieur de la vanne. Le premier siège de vanne est sollicité vers l'élément bille pour venir en prise étanche avec une première partie de l'élément bille. Le second siège de vanne est conçu pour venir en prise étanche avec une seconde partie de l'élément bille, et est serré entre une surface du corps de vanne et une surface de l'adaptateur.
