Title (EN) VALVE, USE OF SUCH VALVE, SEPARATOR COMPRISING SUCH VALVE AND METHOD OF CLEANING A SEPARATOR BODY
(FR) CLAPET, UTILISATION D'UN TEL CLAPET, SÉPARATEUR COMPRENANT UN TEL CLAPET ET PROCÉDÉ DE NETTOYAGE D'UN CORPS DE SÉPARATEUR
Abstract:
(EN) The present disclosure provides a valve (123), comprising a channel body (1231) defining a bent channel space, an elastically flexible membrane (1233), which separates a control space (Sc) from a flow space (Sf) in the channel space, a control connection (1232), providing a fluid connection to the control space (Sc), The control space (Sc) is provided at a radially outermost portion (Co) of the channel space, as per a channel bending radius (Ro), such that the membrane (1233) is flexible between an open position, whereby a cross section of the flow space (Sf) is substantially that of the channel, and a closed position, whereby the membrane substantially seals against a radially innermost portion (Ci) of the channel, as per the channel bending radius (Ri). Use of the valve in a separator is disclosed, as well as a separator comprising such valve and a method of cleaning a separator body.
(FR) La présente invention concerne un clapet (123), comprenant un corps canal (1231) délimitant un espace de canal coudé, une membrane élastiquement flexible (1233), qui sépare un espace de commande (Sc) d'un espace d'écoulement (Sf) dans l'espace de canal, un raccord de commande (1232), assurant un raccordement fluidique à l'espace de commande (Sc), l'espace de commande (Sc) étant disposé au niveau d'une partie radialement la plus à l'extérieur (Co) de l'espace de canal, selon un rayon de courbure de canal (Ro), de telle sorte que la membrane (1233) est flexible entre une position ouverte, moyennant quoi une section transversale de l'espace d'écoulement (Sf) est sensiblement celle du canal, et une position fermée, moyennant quoi la membrane crée sensiblement une étanchéité contre une partie radialement la plus à l'intérieur (Ci) du canal, selon le rayon de courbure de canal (Ri). L'invention concerne également l'utilisation du clapet dans un séparateur, ainsi qu'un séparateur comprenant une telle valve et un procédé de nettoyage d'un corps de séparateur.
