Abstract

Le filtre comprend le boîtier et le couvercle. Le boîtier est constitué par la partie cylindrique et le cône tronqué creux, dont la périphérie de la base la plus grande passe dans un maillage cylindrique formé par des rainures en ligne droite et des raidisseurs concentriques. La paroi du cône tronqué creux est perforée de fenêtres traversantes rectangulaires qui sont proportionnelles à la capacité de passage des trous de maillage cylindriques. Le couvercle est fait d'un seul tenant avec un raccord de passage avec le trou de sortie, et de l'autre côté avec le rebord, à l'intérieur duquel les bords du boîtier sont installés. Le couvercle est pourvu d'un manchon constitué d'une section filetée dans la partie cylindrique du boîtier. Dans le manchon, le clapet de non-retour intégré avec un obturateur est installé, dont le siège est fixé dans le filetage du manchon. La tige est placée dans les trous des guides, installées avec leurs bandes externes dans le manchon avec la possibilité d'un mouvement axial de la tige avec la valve pour une interaction avec le siège lorsqu'elle est exposée à s'écouler depuis le côté du raccord du couvercle. Dans le couvercle, au niveau du bord supérieur du manchon, le collier d'arrêt interne est conçu pour fixer les guides de la tige de clapet de non-retour. L'obturateur de clapet de non-retour est réalisé en forme de champignon. Le résultat obtenu consiste à réduire les dimensions et le poids du système hydraulique, à simplifier la conception des joints et à augmenter la maintenabilité, à simplifier la technologie d'installation dans le système hydraulique, ainsi que d'augmenter la durabilité et la fiabilité du fonctionnement, en raison du placement interne protégé du clapet de non-retour et, par conséquent, de la durée de fonctionnement.
