Abstract

L'invention concerne un système de manocontacteur qui fournit un mécanisme de sécurité pour un équipement dans un environnement de site de puits pour empêcher l'ouverture ou la libération de certains composants lorsqu'une situation à risques existe. Un ensemble manocontacteur du système comprend un diaphragme qui passe à une position étendue sous la forme d'une pression d'un fluide sous pression qui s'écoule à travers un trajet de fluide de l'ensemble. Le diaphragme se couple à une broche qui effectue une transition avec une fléchette sur la base de la pression au niveau du diaphragme. Lorsque la pression atteint ou dépasse un seuil, la fléchette passe à un emplacement proche d'un capteur. Le capteur déclenche l'actionnement d'un commutateur pour empêcher la libération ou l'ouverture d'un connecteur à distance d'une unité hydraulique jusqu'à ce que la pression soit inférieure ou égale au seuil. Le seuil est réglé à une pression sur la base de la situation à risques.
