Title (EN) A NON-RETURN VALVE
(FR) CLAPET DE NON-RETOUR
Abstract:
(EN) A non-return valve includes a cylindrical valve seat insert that defines a fluid passageway and a valve seat terminating the passageway. A valve closure includes a valve flap that is pivotal about a pivot region with respect to the valve seat between a closed condition in which a periphery of the valve flap operatively engages the valve seat to close the fluid passageway and an open condition in which fluid is permitted to flow through the passageway. A biasing mechanism is interposed between the valve flap and an internal surface of the insert to bias the valve flap into the closed condition, the biasing mechanism being configured and arranged with respect to the valve flap such that a level of bias is adjusted to facilitate movement of the valve flap into the open condition.
(FR) L'invention concerne un clapet de non-retour qui comprend un insert de siège de clapet cylindrique qui définit un passage de fluide et un siège de clapet terminant le passage. Une fermeture de clapet comprend un rabat de clapet qui est pivotant autour d'une région de pivot par rapport au siège de clapet entre un état fermé, dans lequel une périphérie du rabat de clapet est en prise de façon fonctionnelle avec le siège de clapet pour fermer le passage de fluide, et un état ouvert, dans lequel un fluide est autorisé à s'écouler à travers le passage. Un mécanisme de sollicitation est interposé entre le rabat de clapet et une surface interne de l'insert pour solliciter le rabat de clapet dans l'état fermé, le mécanisme de sollicitation étant conçu et placé par rapport au rabat de clapet de telle sorte qu'un niveau de sollicitation est ajusté pour faciliter un mouvement du rabat de clapet dans l'état ouvert.
