Title
(EN) SOLENOID PILOT OPERATED AIR ACTIVATED PISTON DRIVEN DOUBLE SEAT ACCUMULATOR DRAIN VALVE
(FR) SOUPAPE DE PURGE D'ACCUMULATEUR A DOUBLE SIEGE ACTIONNEE PAR UN PISTON PNEUMATIQUE PILOTE PAR SOLENOIDE
Abstract
(EN)
A drain valve has an inlet (36) for liquids and small solids, an accumulation chamber (37) and an outlet (17). The outlet has a seal (13) which is connected to an air-activated piston (12). The piston is in turn connected to a positive air pressure inlet (18) via an air communication path (19) and a closure (22). The closure (22) is opened by a closure activation means (29), causing positive air pressure to flow to the piston (12), which briefly causes the outlet seal (13) to be opened, allowing liquids and small solids from the accumulation chamber to be expelled. Upon de-activation by the closure activation means (29), the closure (22) recloses, blocking the supply of positive air pressure to the piston (12).
(FR)
Une soupape de purge possède une admission (36) pour des liquides et des petits solides, une chambre d'accumulation (37) et une sortie (17). La sortie possède un joint d'étanchéité (13) qui est relié à un piston à actionnement pneumatique (12). Le piston est à son tour connecté à une admission (18) à pression d'air positive par l'intermédiaire d'un chemin de communication d'air (19) et une fermeture (22). La fermeture (22) est ouverte par des moyens d'actionnement (29) de ladite fermeture, provoquant un écoulement d'air à pression positive vers le piston (12) lequel provoque une brève ouverture du joint d'étanchéité (13) de la sortie, laissant ainsi sortir les liquides et les petits solides de la chambre d'accumulation. Lors de la désactivation des moyens d'activation (29) de la fermeture, celle-ci (22) se referme et coupe l'alimentation d'air à pression positive vers le piston (12).
