Abstract

Le présent extrait concerne un robinet-vanne qui comprend un corps ayant un passage cylindrique définissant un trajet d'écoulement à travers le robinet, une vanne pour contrôler l'écoulement de fluide à travers le robinet, et une garniture de trajet d'écoulement résistante à l'usure remplaçable dans le trajet d'écoulement. La garniture de trajet d'écoulement comprend un grand nombre de pièces rapportées résistantes à l'usure, y compris les ports de garniture des manchons d'usure du corps du robinet, les sièges de clapet et une pièce rapportée de robinet pour un alésage de trajet d'écoulement à travers le robinet. Chaque siège de clapet remplaçable a un segment racleur pour nettoyer le robinet quand il s'ouvre et se ferme. En inspectant et remplaçant régulièrement les pièces rapportées usées, la durée de vie utile du robinet-vanne peut être prolongée, et la dépense associée à un remplacement et une remise en état du corps de robinet est évitée.
