Abstract

Cette invention concerne une vanne d'alimentation en eau avec fonction empêchant le retour de flux, dans laquelle la pression de retour est produite par le coup du bélier lors de l'ouverture et de la fermeture rapides de la vanne ou lorsque la pression dans un appareil tel qu'une chaudière, dans lequel est introduite de l'eau en circulation, et supérieure à la pression de l'eau, empêchant ainsi le retour de flux de l'eau dans une conduite. Cette vanne d'alimentation en eau comprend: un ensemble de conduites (20) formant une chambre de fluide (21) avec une partie supérieure ouverte, et comportant une conduite d'entrée (22) qui s'étend sur un côté de la chambre de fluide (21) et qui est coudée vers le haut, et une conduite de sortie (23) raccordée à l'autre ouverture de la conduite d'entrée (22); et un couvercle monté mobile sur la chambre de fluide (21) de façon à recouvrir le soufflet (30), et comportant un évidement à ressort (42) dans lequel est inséré un ressort tampon (41), destiné à comprimer le soufflet.
