The solution to the problem of noise reduction of the volume of gas at low flow rates at GDS

The gas-distributing stations have a significant seasonal fluctuations in natural gas consumption in different periods of work. Metering gas distribution stations cannot provide the required measurement accuracy at a low cost natural gas in the summer. To solve this problem, the paper proposed the use of a pulsed control method mode output pressure at gas distribution stations using on-off solenoid valve high pressure normalized with the orifice, ensuring a harmonized work of regulating and flow metering equipment.
Materials and methods
For this article were used experimental process data, confirmation of the results, mathematical methods, illustrative information and validation of the results.
Results
The application of impulse mode is enabled:
1) to provide reliable and quality public regulation of outlet pressure at GDS;
2) to increase runtime period of equipment;
3) to optimize the mode of operation of a gas metering station;
4) to increase the reliability of the reduction unit;
5) to harmonize the requirements of local normative acts and guidance documents the gas metering at low flow rates at GDS.
Сonclusions
Proposed impulse control method is practically grounded. That allows to recommend the use of a two-position solenoid valve high pressure with normalized orifice for implementation it ongas distributed stations to improve efficiency of work flow on site during periods of low flow natural gas.
