Title
(EN) CHECK VALVE AND ASSEMBLY FOR FLUID STORAGE CONTAINER
(FR) CLAPET DE NON-RETOUR ET ENSEMBLE POUR UN RÉCIPIENT DE STOCKAGE DE FLUIDE
Abstract
(EN)
A check valve assembly includes a valve, cam and arm with float rotatably connected to the valve for insertion into a fluid storage container for filling of the container without overfilling. The valve includes a channel of narrowing diameter and restricting member movably retained within the channel. One end of the restricting member rides along the cam profile as the arm rotates the cam with the changing fluid levels. When the fluid reaches maximum fill level, the restricting member contacting the cam drops into the cam valley, driving the restricting member head into engagement with the channel neck walls and automatically sealing off the valve. First and second biasing members are disposed in the channel, preferably around the stem, and collectively provide counter force sufficient to overcome the frictional forces of the seal to open valve and move the restricting member upward.

La présente invention concerne un ensemble clapet de non-retour qui comprend un clapet, une came et un bras ayant un flotteur relié de manière rotative au clapet pour être inséré dans un récipient de stockage de fluide pour le remplissage du récipient sans surremplissage. Le clapet comprend un canal de diamètre de rétrécissement et un élément de restriction retenu de façon mobile à l'intérieur du canal. Une extrémité de l'élément de restriction se déplace le long du profil de came au fur et à mesure que le bras fait tourner la came avec les niveaux de fluide changeant. Lorsque le fluide atteint un niveau de remplissage maximal, l'élément de restriction entrant en contact avec la came tombe dans le creux de came, entraînant la tête d'élément de restriction en prise avec les parois de col de canal et scellant automatiquement le clapet. Des premier et second éléments de sollicitation sont disposés dans le canal, de préférence autour de la tige, et fournissent collectivement une contre-force suffisante pour surmonter les forces de frottement du joint d'étanchéité pour ouvrir le clapet et pour déplacer l'élément de restriction vers le haut.
