Title (EN) LIQUID PROPORTIONING SYSTEM
(FR) SYSTEME DE DOSAGE DE LIQUIDE
Abstract:
(EN) A liquid proportioning system controls the mixing of water and a fire retardant concentrate through the operation of a diaphragm operated valve. The diaphragm valve controls the flow rate of concentrate in response to the sensed pressure of water supplied to a proportioner, so that a predetermined proportion of concentrate and water is maintained.
(FR) L'invention concerne un système de dosage de liquide qui régule un mélange d'eau et d'un concentré ignifuge au moyen d'une vanne actionnée par une membrane. La vanne à membrane régule de débit du concentré en réponse à le pression détectée d'eau fournie à un doseur, de façon à maintenir une dose prédéterminée de concentré et d'eau.
