(EN) PIPE FITTING FOR PROVIDING EASY LOCKING WITH APPROPRIATE TORQUE
(FR) RACCORD DE TUYAU PERMETTANT UN VERROUILLAGE FACILE AVEC UN COUPLE APPROPRIÉ
front page image
Abstract
(EN) The present invention relates to a pipe fitting apparatus providing easy locking with an appropriate torque, and more specifically, relates to a pipe fitting apparatus providing easy locking with an appropriate torque for which the possibility of breakage and leakage has been eliminated by being easily configured in a manner that the locking of the pipe fitting apparatus used to connect pipes is performed with an appropriate torque. The pipe fitting apparatus has a fitting body, a force control ferrule, and a fixing nut. The fitting body has a first connecting portion with an inner threaded surface, a second connecting portion having an outer threaded portion, and a ferrule seating portion where the force control ferrule is provided. The fixing nut has an inner threaded portion for engaging with the second connecting portion of the fitting body and an inclined pressure surface for abutting against the force control ferrule.
(FR) La présente invention concerne un appareil de raccord de tuyau permettant un verrouillage facile avec un couple approprié, et concerne plus précisément un appareil de raccord de tuyau permettant un verrouillage facile avec un couple approprié pour lequel la possibilité de rupture et de fuite a été éliminée au moyen d'une configuration facile de telle sorte que le verrouillage de l'appareil de raccord de tuyau utilisé pour raccorder des tuyaux est réalisé avec un couple approprié. L'appareil de raccord de tuyau comprend un corps de raccord, une bague de commande de force et un écrou de fixation. Le corps de raccord comprend une première partie de raccordement présentant une surface filetée interne, une seconde partie de raccordement présentant une partie filetée externe, et une partie d'appui de bague dans laquelle la bague de commande de force est disposée. L'écrou de fixation comprend une partie filetée interne destinée à venir en prise avec la seconde partie de raccordement du corps de raccord et une surface de pression inclinée destinée à venir en butée contre la bague de commande de force.
