Title (EN) SYSTEM FOR REGULATING A LIQUID IN A CIRCUIT
(FR) SYSTÈME DE RÉGULATION D'UN LIQUIDE DANS UN CIRCUIT
Abstract:
(EN) The present invention relates to a system for regulating a liquid flowing in a circuit (10) able to reverse the flow direction, the system comprising: - a regulating valve (200) comprising at least one inlet and one outlet and comprising a movable covering flap, the position of which makes it possible to adjust the flow rate of the liquid through the valve (200), - an expansion reservoir (100) in communication with the liquid flowing in the circuit (1) and intended to contain liquid and a compensating gas, - the expansion reservoir (100) is connected to the circuit (1) by means of the valve (200) and such that the expansion reservoir (100) communicates with at least one from among the inlet and the outlet of the valve (200) irrespective of the position of the covering flap, the position of the covering flap being independent of the pressure of the fluid in the expansion reservoir (100). The invention also relates to a circuit incorporating this system as well as a use of said system.
(FR) La présente invention concerne un système de régulation d'un liquide circulant dans un circuit (10) apte à inverser le sens de circulation, le système comprenant : - une vanne (200) de régulation comprenant au moins une entrée et une sortie et comprenant un obturateur mobile dont la position permet de réguler le débit de l'écoulement du liquide à travers la vanne (200), - un réservoir d'expansion (100) en communication avec le liquide s'écoulant dans le circuit (1) et destiné à contenir du liquide et un gaz de compensation, - le réservoir d'expansion (100) est raccordé au circuit (1) par l'intermédiaire de la vanne (200) et de manière à ce que le réservoir d'expansion (100) communique avec au moins l'une parmi l'entrée et la sortie de la vanne (200) quelle que soit la position de l'obturateur, la position de l'obturateur étant indépendante de la pression du fluide dans le réservoir d'expansion (100). L'invention concerne également un circuit intégrant ce système ainsi qu'une utilisation de ce système.
