Abstract

LE DISPOSITIF SELON L'INVENTION COMPORTE UNE CONDUITE 1 INTERCALEE DANS LE CIRCUIT OU LA CANALISATION, UN PISTON 3 DEPLACABLE PAR RAPPORT A LA CONDUITE ET AGENCE DE FACON A VENIR OBTURER, DANS UNE DE SES POSITIONS EXTREMES, UNE SECTION DE PASSAGE DU FLUIDE A TRAVERS LA CONDUITE, ET DE FACON A FOURNIR, DANS UNE AUTRE POSITION, UN CANAL D'ECOULEMENT POUR LE FLUIDE, DES MOYENS 4, 31 A 34 POUR REGLER LA SECTION DU CANAL D'ECOULEMENT DE MANIERE A ETABLIR, EN REGIME NORMAL, UNE DIFFERENCE DE PRESSION DE FLUIDE DETERMINEE ENTRE LES COTES AMONT ET AVAL DU PISTON, ET DES MOYENS 4, 6 POUR MAINTENIR LE PISTON EN EQUILIBRE, A L'ENCONTRE DE LA DIFFERENCE DES PRESSIONS S'EXERCANT SUR SES COTES AMONT ET AVAL, JUSQU'A UNE VALEUR DE SEUIL DE CETTE DIFFERENCE. UN DEPASSEMENT DE CETTE VALEUR DE SEUIL DU PAR EXEMPLE A UNE RUPTURE DE CANALISATION DANS LA PARTIE SITUEE EN AVAL DU DISPOSITIF ENTRAINE UN DEPLACEMENT DU PISTON JUSQU'A LA POSITION D'OBTURATION DE LA CONDUITE. LE DISPOSITIF EST UTILISABLE NOTAMMENT DANS UNE CANALISATION DE DISTRIBUTION D'UN GAZ COMPRIME, D'UNE VAPEUR SOUS PRESSION, OU D'UN LIQUIDE COMME L'EAU OU LE PETROLE.
