Title (EN) A SPHERICAL PLUG VALVE AND A METHOD FOR MANUFACTURING THE SAME
(FR) VANNE A BOISSEAU SPHERIQUE ET PROCEDE DE FABRICATION
Abstract:
(EN) A valve for a fluid distribution system is disclosed, which has a spherical plug (1), a control stem (4), sealing rings (5, 6) and coupling sleeves (2, 3) enclosed into a body of a plastic material (8). Said enclosed valve members are maintained in position and forced against each other by said body with a predetermined pressure to ensure sealing without impairing the plug movements. For manufacturing the valve, the valve members are placed into a die of a press for injection molding of plastic materials and plastic material is injected into the die. After setting, the plastic material forms the valve body.
(FR) On décrit une vanne destinée à un système distributeur de fluide et possédant un boisseau sphérique (1), une tige de commande (4), des anneaux d'étanchéité (5, 6) et des manchons d'accouplement (2, 3) enfermés dans un corps de matière plastique (8). Ledit corps sert à maintenir en place lesdits éléments enfermés de la vanne et à les serrer les uns contre les autres avec une pression prédéterminée suffisante pour assurer l'étanchéité sans pour autant entraver les déplacements du boisseau. Afin de fabriquer la vanne, on place les éléments de la vanne dans la filière d'une presse d'injection et l'on injecte de la matière plastique dans la filière. Après le durcissement, la matière plastique forme le corps de la vanne.
