Title
(EN) FLOW-THROUGH, IN-LINE FILTER APPARATUS AND IMPROVED COUPLING DEVICE
(FR) APPAREIL DE FILTRATION EN LIGNE A CIRCULATION ET DISPOSITIF D'ACCOUPLEMENT PERFECTIONNE
Abstract
(EN)
A union including a pair of junction elements (100, 102) for attachment to ends of flow lines to be connected with a coupling nut (104). One of the elements (100) is provided with a coupling face (114) having at least one annular groove (116) formed therein circumscribing the fluid passageway. The sidewalls of the groove or grooves are angularly inclined relative to each other so that the width of the groove decreases with depth. The opposing face (138) of the second junction element (102) is provided with an annular rib (140), the transverse thickness of which is adapted to mate with the opposing groove (116) of the first element such that when the nut (104) is used to draw the two junction elements together, the rib (140) mates with the groove (116) and forms a seal therebetween.
(FR)
Un raccord comprenant une paire d'éléments de raccordement (100, 102) conçus pour être fixés aux extrémités de lignes d'écoulement destinées à être assemblées avec un manchon de serrage (104). Un des éléments (100) est doté d'une surface d'accouplement (114) dans laquelle au moins une gorge annulaire (116) délimitant le passage de fluide est formée. Les parois latérales de la ou des gorges annulaires sont inclinées les unes par rapport aux autres selon un certain angle de sorte que la largeur de la gorge décroisse avec la profondeur. La face opposée (138) du second élément de raccordement (102) présente une côte annulaire (140) dont l'épaisseur transversale est conçue pour s'adapter dans la gorge opposée (116) du premier élément de sorte que, lorsque le manchon (104) est utilisé pour serrer ensemble les éléments de raccordement, la côte (104) s'adapte de manière étanche dans la gorge (116).
