Title (EN) VALVE FOR CONTROLLING AND SHUTTING OFF A GAS OR LIQUID FLOW
(FR) VANNE DE REGLAGE ET D'ARRET D'UN FLUIDE GAZEUX OU LIQUIDE
Abstract:
(EN) A valve including a body (2) provided with two intersecting bores respectively defining a fluid flow channel (3) and a housing containing an actuating mechanism for actuating a needle (19) which has a tapered portion (28) at one end for engaging the fluid flow port of a seat between the first flow channel and a second flow channel. The needle (19) is secured to a coaxial sleeve (34) and the seat includes a cylindrical portion (31) arranged to be engageable with the sleeve (34) to provide automatic centring of the tapered portion (28) and maintain the coaxiality thereof. Said valve is particularly useful in chlorinators.
(FR) La vanne selon l'invention comprend un corps (2) muni de deux alésages sécants constituant respectivement un conduit de circulation de fluide (3) et un logement pour un mécanisme d'actionnement d'un pointeau (19) dont une extrémité comprend une partie effilée (28) apte à venir s'engager dans l'orifice de passage de fluide d'un siège séparant le premier conduit de circulation d'un deuxième conduit de circulation. Le pointeau (19) est solidaire d'un fourreau coaxial (34) et le siège comporte une forme cylindrique (31) disposée de manière à s'engager dans le fourreau (34) en assurant un autocentrage et un maintien de la coaxialité de la partie effilée (28). L'invention s'applique notamment à la réalisation d'un chloromètre.
