Title
(EN) FREE-FLOW PROTECTION DEVICES AND METHODS
(FR) DISPOSITIFS ET PROCEDES DE PROTECTION CONTRE UN ECOULEMENT LIBRE
Abstract
(EN)
The present invention describes a free-flow protection device (130). A pump (110) and tube (100) are provided where the pump affects the flow of fluid through the tube. The device occludes the tube when the tube becomes disengaged from the pump. The device may be internal or external to the tube. The tube may attach to the pump with a pressure plate (120).
(FR)
La présente invention concerne un dispositif de protection contre un écoulement libre. Une pompe et un tube sont prévus à l'endroit où la pompe influe sur le débit d'un fluide dans le tube. Ce dispositif ferme le tube au moment où le tube est débranché de la pompe. Ce dispositif peut être interne ou externe par rapport au tube. Le tube peut se fixer à la pompe au moyen d'une plaque de pression.
