Abstract

L'invention est relative à un circuit de commande de vanne hydraulique. Ce circuit comporte une vanne de sectionnement normalement fermée branchée entre la source de fluide hydraulique et l'orifice d'entrée du mécanisme d'actionnement de la vanne de sécurité; des moyens pour ouvrir la vanne de sectionnement en réponse à une augmentation de pression en provenance de la source de fluide; et des moyens formant vannes pour réduire la pression de fluide au niveau de l'orifice d'entrée du mécanisme d'actionnement lorsque la vanne de sectionnement est fermée, lesdits moyens formant vanne étant couplés à l'orifice d'entrée du mécanisme d'actionnement de la vanne de sécurité. Application : puits de pétrole brut et de gaz.
