Title
(EN) LIQUID CONSTANT RATE DISCHARGE METHOD AND DEVICE
(FR) PROCEDE ET DISPOSITIF DE DISTRIBUTION DE LIQUIDE A VITESSE CONSTANTE
Abstract
(EN)
A liquid discharge method and device that, on the basis of mechanically opening and closing the discharge opening in a discharge valve, improve the ability to cut off liquid upon stoppage of discharge without the danger of the filler being destroyed and that fully prevents leakage of liquid. The method of discharging liquid from a liquid storage vessel through a discharge valve at a constant rate, characterized by comprising the steps of controlling the pressure of the liquid being fed from the liquid storage vessel to the discharge valve, according to the liquid pressure in the region near the discharge opening in the discharge valve, and mechanically opening and closing the discharge opening; and the device for discharging liquid from a liquid storage vessel through a discharge valve at a constant rate, characterized in that the liquid storage vessel of this device is provided with a pressing means for pressing the stored liquid at a pressure depending on the viscosity thereof, and in that the discharge valve communicating with the liquid storage vessel has a construction such that its discharge opening is mechanically opened and closed.

On décrit un procédé et un dispositif de distribution de liquide qui, sur la base de l'ouverture et de la fermeture mécaniques de l'ouverture de sortie formée dans une soupape d'échappement, améliorent la capacité d'arrêter le liquide lorsque la distribution est stoppée sans pour autant risquer d'endommager l'orifice de remplissage et qui empêche véritablement toute fuite de liquide. Le procédé de distribution de liquide situé dans un réservoir de stockage de liquide par une soupape de distribution opérant à vitesse constante se caractérise en ce qu'il comprend les étapes suivantes : la surveillance de la pression du liquide envoyé du réservoir de stockage de liquide à la soupape de distribution, en fonction de la pression du liquide dans la région proche de l'ouverture de sortie prévue dans la soupape de distribution et l'ouverture et la fermeture mécaniques de l'ouverture de sortie. Le dispositif servant distribuer le liquide d'un réservoir de stockage de liquide par une soupape de distribution opérant à vitesse constante se caractérise en ce que le réservoir de stockage de liquide de ce dispositif est doté d'un système de compression qui comprime le liquide stocké à une pression qui dépend de sa viscosité, et en ce que la soupape de distribution qui communique avec le réservoir de stockage de liquide est construite de sorte que son ouverture de sortie puisse être ouverte et fermée de manière mécanique.
