An outflow regulator for a gravity-fed liquid outlet of a liquid reservoir comprising a restriction plate mountable within the liquid outlet for limiting a flow rate of an effluent. The restriction plate allows a lower passage for the effluent when a first level of liquid is reached within the liquid reservoir, and an upper passage for the effluent when a second level of liquid is reached. The regulator also comprises a flapgate pivotable between a closed position where the flapgate covers the lower passage of the restriction device and an open position away from the restriction plate. When the flapgate is in the closed position, the effluent is free to flow out though the upper passage. A float counterweight switches the flapgate between the opened position and closed position according to the liquid level in the reservoir.

Régulateur de débit sortant pour écoulement de liquide alimenté par gravité d~un réservoir de liquide comportant une plaque de restriction pouvant être montée dans l~écoulement de liquide afin de limiter le débit d~un effluent. La plaque de restriction autorise un passage inférieur pour l~effluent quand un premier niveau de liquide est atteint à l~intérieur du réservoir de liquide, et un passage supérieur pour l~effluent quand un second niveau de liquide est atteint. Le régulateur comporte aussi un clapet pouvant pivoter entre une position fermée où le clapet couvre le passage inférieur du dispositif de restriction et une position ouverte éloignée de la plaque de restriction. Quand le clapet est à la position fermée, l~effluent s~écoule librement par le passage supérieur. Un contrepoids à flotteur fait basculer le clapet entre la position ouverte et la position fermée en fonction du niveau de liquide dans le réservoir.
