Title (EN) PLASTIC CONTROL VALVE
(FR) SOUPAPE DE REGULATION EN PLASTIQUE
Abstract:
(EN) A free draining, corrosive resistant valve for regulating the flow of corrosive fluids therethrough includes a plastic valve housing (10). An inlet passage (16) extends into the housing and upwardly therein terminating in a valve seat (20). An inclined panel (24) surrounds the inlet passage below the valve seat. An outlet passage (26) extends from the lowermost portion of the inclined panel through the housing. A plastic valve poppet (46) is located above the seat having a diaphragm (52) therearound with an upwardly extending stem (56). A plastic retainer (58) is located above the diaphragm into which the stem extends. The retainer is adapted for affixing the diaphragm in a sealing relationship to the valve housing.
(FR) Soupape à écoulement libre et résistant à la corrosion, servant à réguler l'écoulement de fluides corrosifs et comprenant un logement de soupape en plastique (10). Un passage d'arrivée (16) se prolonge à l'intérieur du logement et vers le haut de façon à aboutir à un siège de soupape (20). Un panneau incliné (24) entoure le passage d'arrivée au-dessous du siège de soupape. Un passage de sortie (26) se prolonge à partir de la partie la plus basse du panneau incliné à travers le logement. Un champignon de soupape en plastique (46) est situé au-dessus du siège, est entouré par une membrane (52), et comporte une tige s'étendant verticalement (56). Un élément de retenue en plastique (58) est situé au-dessus de la membrane dans laquelle s'étend la tige. L'élément de retenue est adapté à fixer la membrane de manière étanche au logement de soupape.
