Remote-operated system for automatically regulating pressure, and method for implementing such a system

Abstract

The remote-operated system (100) for automatically regulating pressure between an upstream gas pipe (101) and a downstream gas pipe (102) comprises: - a controlled regulator (105), connected, on the one hand, to the upstream gas pipe and, on the other hand, to the downstream gas pipe, - a control mechanism (110) for controlling the controlled regulator, - at least two direct-acting regulators (130, 135) each configured to produce a drive pressure as a function of a predetermined control pressure, at least two control pressures being different, - a drive pipe (115) connecting at least two said direct-acting regulators and the control mechanism of the controlled regulator, and - a remote-operated mechanism (160) for selecting the control pressure to be implemented and configured to pneumatically activate the direct-acting regulator corresponding to the control pipe selected.
