Abstract

CLAPET DE RETENUE DESTINE A ETRE MONTE DANS UNE CONDUITE D'ECOULEMENT DE FLUIDES. IL COMPORTE UN CORPS ANNULAIRE SUR LEQUEL DEUX CLAPETS DE FORME PARTIELLEMENT CONIQUE PIVOTENT ENTRE DES POSITIONS DE FERMETURE ET D'OUVERTURE, AU-DESSUS D'UN ORIFICE DANS LEQUEL LES FLUIDES PEUVENT S'ECOULER. LA RESISTANCE DES OBTURATEURS ET L'ECOULEMENT DU FLUIDE DANS LE CLAPET, LORSQUE LES OBTURATEURS SONT EN POSITION D'OUVERTURE, SONT AMELIORES PAR LE FAIT QUE LA SURFACE INTERIEURE CONCAVE DE CHAQUE OBTURATEUR PRESENTE UNE FORME ELLIPSOIDALE. DOMAINE D'APPLICATION: PROPULSEURS A REACTION.
