Abstract

L'invention concerne les appareils de contrôle par ultra-sons. Elle a pour objet un dispositif de commande de l'alimentation en liquide de couplage pour une tête de contrôle ultra-sonore d'un corps défilant devant ladite tête. Ce dispositif comprend une conduite principale 4 équipée d'une vanne doseuse 3 à réglage continu et quatre conduits 9 à 12 branchées en parallèle et équipées de vannes de commutation 5 à 8 actionnées par une logique binaire de commande 13 à partir d'un capteur 14 de vitesse de défilement. Application au contrôle ultra-sonore de bandes de tôle.The invention relates to ultrasonic testing devices. It relates to a device for controlling the supply of coupling liquid for an ultrasonic control head of a body moving past said head. This device comprises a main pipe 4 equipped with a continuously adjustable metering valve 3 and four pipes 9 to 12 connected in parallel and equipped with switching valves 5 to 8 actuated by a binary control logic 13 from a sensor 14 scroll speed. Application to the ultrasound control of sheet metal strips.
