Title (EN) SWING CHECK VALVE AND METHOD FOR REPAIRING SAME
(FR) SOUPAPE DE RETENUE OSCILLANTE ET PROCEDE PERMETTANT DE LA REPARER
Abstract:
(EN) A swing check valve (10), which is adapted for automatically inhibiting back flow of fluid from an outlet thereof to an inlet thereof, includes a clapper member (18) and a housing (12). The housing (12) has a first body portion (20), which includes its own valve seat (32) and its own mounting mechanism (56) adapted to removably mount the clapper member (18) therefrom when the first body portion (20) is positioned adjacent to the inlet of the valve (10). The housing (12) also has a second body portion (22), which includes its own valve seat (34) and its own mounting mechanism (64) adapted to removably mount the clapper member (18) therefrom when the second body portion (22) is positioned adjacent to the inlet of the valve (10). The first and second body portions (20, 22) are removably connected to each other in an end-to-end fashion and are interchangeable with each other, whereby each body portion may be utilized as a replacement for the other body portion.
(FR) L'invention concerne une soupape de retenue oscillante (10), conçue pour empêcher automatiquement le reflux d'un fluide de son orifice de sortie vers son orifice d'entrée. Ladite soupape comprend un clapet (18) et un corps (12). Le corps (12) comporte une première partie (20) qui comprend son propre siège de soupape (32) et son propre mécanisme de montage (56) conçu pour permettre de monter, de façon amovible, le clapet (18) lorsque cette première partie (20) est placée à côté de l'entrée de la soupape (10). Le corps (12) comporte également une seconde partie (22) qui comprend son propre siège de soupape (34) et son propre mécanisme de montage (64) conçu pour permettre de monter, de façon amovible, le clapet (18) lorsque cette seconde partie (22) est placée à côté de l'orifice d'entrée de la soupape (10). La première et la deuxième parties (20, 22) du corps peuvent être reliées l'une à l'autre, de façon amovible, bout à bout, et sont interchangeables, chaque partie pouvant être utilisée pour remplacer l'autre partie.
