CA 2210995

A fluid valve (10) has a housing (12) formed by first and second halves (14, 16) which combine at mating surfaces (26) to form a cavity (22) with an inlet (18) in the first half and an outlet (18) in the second half. The mating surface of each half includes a notch (32) extending between an outer edge of mating surface and the cavity, and includes an annular recess (28) around the cavity. A pad (40) is formed on each mating surface between the cavity and the annular recess, and has a groove (42) that forms a bushing when the first and second units are connected. A butterfly valve member (82) is located within the cavity and is mounted on a valve stem (76). The valve stem has an end that rides in the bushing and a portion that passes through the notches in the housing halves. An annular seal (44) fits within the recesses to prevent fluid leakage between the two housing halves and also seals around the valve stem portion. In addition the butterfly valve member engages the seal in a closed state of the valve.

Une vanne (10) à fluide comporte un logement (12) constitué par une première et une deuxième moitiés (14, 16) qui se combinent sur des surfaces (26) de raccordement pour former une cavité (22), avec une entrée (18) dans la première moitié et une sortie (18) dans la deuxième. La surface de raccordement de chaque moitié présente une gorge (32) qui va de son arête extérieure à la cavité, et elle présente aussi un évidement annulaire (28) qui fait le tour de la cavité. Un patin (40) se trouve sur chaque surface de raccordement, entre la cavité et l'évidement annulaire, et il présente une encoche (42) qui forme un manchon quand les deux unités sont réunies. Un papillon de vanne (82) se trouve dans la cavité et il est monté sur une tige (76) de vanne. La tige de vanne a une extrémité qui tourne dans le manchon et une section qui passe dans les gorges des moitiés de logement. Un joint annulaire (44) est logé dans les évidements pour empêcher les fuites entre les deux moitiés du logement et il assure aussi l'étanchéité autour du tronçon de tige de vanne. En outre, le papillon s'applique sur le joint quand la vanne est fermée.
