Abstract

Current natural gas measurement and regulation systems are sensitive to loss of electrical power, which can cause brownouts and curtailment of power in the local area if power systems reliant on natural gas are downstream from the station. A system for regulating the flow of natural gas and for guaranteeing the flow of natural gas from a source to at least one specific flow line even when the system is not provided with electrical power may be described. Such a system may include at least one of each of: a low-pressure regulation system, a high-pressure regulation system, an inlet gas filter, a relief valve, a low select relay, a differential pressure pneumatic relay, a reset relay, a 5-way universal relay, an electromechanically operated valve, a first manual multi-way valve, a second manual multi-way valve, a high calibration valve, a low calibration valve, a filter, and/or a differential pressure measurement system.

Dependent claims

A gas flow regulating system comprising:

a gas-pressure regulation system receiving a gas from outside the gas flow regulating system, protecting the gas flow regulating system from an overpressure of the gas and supplying a control gas and a power gas to the gas flow regulating system;
a differential pressure system receiving the control gas from the gas-pressure regulation system and relaying the control gas in the gas flow regulating system, wherein the differential pressure system comprises;
a differential pressure pneumatic relay receiving the control gas from the gas-pressure regulation system and relaying the control gas to a control gas relay system;
a high calibration valve connected to the differential pressure pneumatic relay;
a low calibration valve connected to the differential pressure pneumatic relay;
a differential pressure measurement system provided between the high calibration valve and the low calibration valve;
and
a filter provided between the high calibration valve and the differential pressure measurement system;
the control gas relay system receiving the control gas from at least one of the gas-pressure regulation system and the differential pressure system;
wherein the differential pressure pneumatic relay relays the control gas to the control gas relay system when a differential gas pressure reaches a predetermined value;
and
a multi-way universal relay receiving the power gas for an actuator from the gas-pressure regulation system and receiving the control gas from the control gas relay system.
