Abstract

L'invention concerne un dispositif de coupure de sécurité de fluide (10) installé dans un trajet de transport de fluide. Le dispositif de coupure de sécurité de fluide (20) comprend un commutateur composite sensible (25) destiné à couper l'écoulement glissant du fluide, à éliminer la coupure et à régler une coupure d'écoulement glissant. Le dispositif de coupure peut couper instantanément l'évacuation du fluide lorsque le fluide s'écoule avec glissement dans le trajet de transport à un débit important inapproprié ; le commutateur composite peut être pressé pour éliminer la coupure d'écoulement glissant une fois la cause de l'écoulement glissant du fluide exclue ; le commutateur composite peut également être réglé pour modifier la réponse du commutateur composite à la coupure d'écoulement glissant.
