Abstract

Le dispositif de contrôle de rupture des flexibles permet d'éviter toute pollution en raison de la fiabilité de la détection. La canalisation témoin 30 est incorporée à l'armature du flexible 29 de telle sorte que toute rupture de 29 provoque nécessairement celle de 30. La canalisation 30, alimentée par une source à pression constante 16, est connectée par 19 et 20 à un distributeur 21 déclenchant la fermeture de l'alimentation du flexible 29 dès que 20 subit une chute de pression due à la rupture de 30. L'invention s'applique à toute canalisation flexible dont la rupture doit déclencher un signal ou la fermeture d'une vanne.The hose breakage control device prevents any pollution due to the reliability of the detection. The control line 30 is incorporated into the armature of the flexible 29 so that any rupture of 29 necessarily causes that of 30. Line 30, supplied by a constant pressure source 16, is connected by 19 and 20 to a distributor 21 triggering the closure of the supply of the flexible 29 as soon as 20 undergoes a pressure drop due to the rupture of 30. The invention applies to any flexible pipe whose rupture must trigger a signal or the closing of a valve.
