Remotely operated automatic pressure control system and method for implementing such a system

Abstract

TITLE OF THE INVENTION: REMOTELY OPERATED AUTOMATIC PRESSURE REGULATION SYSTEM AND METHOD FOR IMPLEMENTING SUCH A SYSTEM The remotely operated automatic pressure regulation system (100) between an upstream gas line (101) and a downstream gas line (102) comprises: - a pilot-operated regulator (105), connected, on the one hand, to the upstream gas line and, on the other hand, to the downstream gas line, - a pilot-operated mechanism (110) for piloting the regulator, - at least two direct-acting regulators (130, 135) each configured to produce a drive pressure based on a predetermined pilot pressure, at least two pilot pressures being different, - a drive line (115) connecting at least two of said direct-acting regulators and the pilot-operated regulator's drive mechanism, and - a remotely operated mechanism (160) for selecting the pilot pressure to be applied. The system is configured to pneumatically activate the direct-acting governor corresponding to the selected pilot control. Figure for abbreviation: Figure 1
