Abstract

"REGULADOR DE ESCOAMENTO PARA ESCOAMENTO DE FLUIDO POR GRAVIDADE CONTROLADO, SISTEMA DE PURIFICAçãO, E, DISPOSITIVO PARA PURIFICAçãO DE áGUA EM ESCOAMENTO POR GRAVIDADE PARA A PURIFICAçãO DE áGUA PARA CONSUMO DOMéSTICO". A invenção fornece um regulador de escoamento para escoamento de fluido por gravidade controlado que compreende: um reservatório de controle de escoamento adaptado para descarregar o volume requerido de fluido e que compreende, no mínimo, uma entrada para a introdução do fluido no reservatório; no mínimo uma descarga por sifão conectada operacionalmente ao reservatório de controle de escoamento e adaptada para controlar a vazão do fluido a partir do reservatório. O regulador de escoamento é particularmente adequado para a provisão de controle sobre o escoamento de água em sistemas de purificação de água, especialmente dispositivos de purificação de água com escoamento por gravidade para a purificação de água para consumo doméstico."CONTROLLED GRAVITY FLOW DRAIN FLOW REGULATOR, PURIFICATION SYSTEM, AND, GRAVITY FLOW WATER PURIFICATION DEVICE FOR PURIFICATION OF DOMESTIC CONSUMPTION". The invention provides a gravity controlled fluid flow regulator comprising: a flow control reservoir adapted to discharge the required volume of fluid and comprising at least one inlet for introducing fluid into the reservoir; at least one siphon discharge operably connected to the flow control reservoir and adapted to control fluid flow from the reservoir. The flow regulator is particularly suited for providing control over water flow in water purification systems, especially gravity flow water purification devices for domestic water purification.
