Title
(EN) VALVE WITH INHERENT ENHANCED TURBULENT FLOW METERING DEVICE AND FLOW REGULATION
(FR) VANNE AVEC DISPOSITIF INHÉRENT AMÉLIORÉ DE MESURE DE FLUX TURBULENT ET DE RÉGULATION DE FLUX
Abstract
(EN)
A valve incorporates a device causing turbulents in the water stream just before passing over the turbine fins of the flow sensor. The device actually increases the Reynolds number or turbulence of the water stream increasing the contact of the water on the turbine. This causes the turbine to rotate more efficiently for the given flow volume passing over the flow measuring device. The improved efficiency results in better accuracy and performance over the entire flow range. In one embodiment the turbulent device forces the flow stream to rotate counter clockwise and hit the turbine fins causing higher force which makes the turbine turn more efficiently. The turbine is designed such that the major portion of the fin surface area is perpendicular to the turbulent flow stream. This opposed direction causes more force to be placed on the turbine fin by the water stream.

L'invention concerne une vanne qui incorpore un dispositif créant des turbulences dans le courant d'eau, juste avant que celui-ci ne passe par les pales de la turbine du détecteur de flux. Le dispositif augmente en fait le nombre de Reynolds ou la turbulence du courant d'eau, augmentant ainsi le contact de l'eau sur la turbine. Ceci fait que la turbine tourne plus efficacement par rapport au volume donné du flux qui passe par le dispositif de mesure de flux. Cette efficacité améliorée a pour résultat une précision et des performances améliorées sur la totalité de la plage de flux. Dans un mode de réalisation, le dispositif turbulent force le flux à tourner dans le sens inverse des aiguilles d'une montre et à frapper les pales de la turbine de manière à créer une force supérieure, ce qui fait que la turbine tourne de manière plus efficace. La turbine est conçue de telle sorte que la majeure partie de la surface des pales est perpendiculaire au flux turbulent. Cette direction opposée fait que le courant d'eau applique une force supérieure aux pales de turbine.
