Title (EN) AIR-RETENTION VALVE FOR PRESSURISED WATER RESERVOIR
(FR) VALVE DE RETENUE D'AIR POUR RÉSERVOIR D'EAU SOUS PRESSION
(PT) VALVULA DE RETENÇÃO DE AR PARA RESERVATÓRIO PRESSURIZADO DE ÁGUA
Abstract:
(EN) Air retention valve to be used in pressurized water tanks comprises: a tube (6) for water circulation with the outside of the tank (a) having a protuberant top (3) into the interior of the tank (a); a floating body (1) vertically displaceable between an upper position and a lower position; one or more guides (5) for vertically guiding the displacement of the floating body (1); and a lid (2) joined to the floating body (1) for covering the top (3) of the tube (6) and the outer surface surrounding said top (3) when the floating body (1) is in the lower position corresponding to a predetermined minimum level of water in the tank (a). A pressurized water tank (a) having such an air retention valve (b) is also disclosed.
(FR) La présente invention concerne une valve destinée à être utilisée dans des réservoirs d'eau sous pression, comprenant : un tube (6) de circulation d'eau relié à l'extérieur du réservoir (a) et doté d'une partie supérieure (3) faisant saillie vers l'intérieur du réservoir (a); un corps flottant (1) verticalement déplaçable entre une position supérieure et une position inférieure; un ou plusieurs éléments de guidage (5) destinés à guider verticalement le déplacement du corps flottant (1); un couvercle (2) solidaire du corps flottant (1) et servant à fermer la partie supérieure (3) du tube (6) et la surface extérieure située autour de ladite partie supérieure (3), lorsque le corps flottant (1) se trouve dans la position inférieure correspondant à un niveau minimal prédéterminé d'eau dans le réservoir (a). L'invention concerne également un réservoir (a) d'eau sous pression comprenant cette valve de retenue d'air (b).
(PT) Uma válvula de retenção de ar destinada a ser usada em reservatórios pressurizados de água compreende: um tubo (6) para circulação de água com o exterior do reservatório (a), tendo um topo (3) protuberante para o interior do reservatório (a); um corpo flutuante (1) verticalmente deslocável entre uma posição superior e uma posição inferior; uma ou mais guias (5) para guiar verticalmente o deslocamento do corpo flutuante (1); e uma tampa (2) solidária com o corpo flutuante (1) para tapar o topo (3) do tubo (6) e a superfície exterior circundante ao referido topo (3) quando o corpo flutuante (1) está na posição inferior correspondente a um nível mínimo predeterminado de água no reservatório (a). Um reservatório (a) pressurizado de água que compreende uma tal válvula de retenção (b) também é divulgado.
