Abstract
L'invention concerne une soupape de retenue à fermeture lente par micro-résistance, apte à empêcher la contamination, et un système de drainage industriel. La soupape de retenue comprend : un corps (1) de soupape, un disque (2) de soupape, une tige (3), un cylindre de piston et un mécanisme amortisseur. Une première chambre (A) et une seconde chambre (B), en communication l'une avec l'autre et aptes à être traversées par un fluide actif, sont disposées dans le corps (1) de soupape. Le mécanisme amortisseur peut amortir le mouvement d'un piston (20). Une chambre intermédiaire au niveau d'une extrémité, éloignée de la tige (3), du cylindre de piston est en communication avec la seconde chambre (B). Un élément isolant extensible est disposé dans la chambre intermédiaire et utilisé pour isoler un fluide amortisseur, dans le cylindre de piston, du fluide actif en provenance de la seconde chambre (B). La soupape de retenue peut réduire considérablement le phénomène de coup de bélier, et le fluide amortisseur est isolé du fluide actif par l'élément isolant, évitant ainsi une défaillance de la soupape de retenue pouvant résulter d'un blocage provoqué par des impuretés dans le fluide actif, et empêchant la contamination du fluide actif par le fluide amortisseur.
