SYSTEM FOR CONTROL AND REGULATION OF PIPELINE OPERATION MODE Russian patent published in 2023 - IPC F17D5/00 

FIELD: pipeline transport.

SUBSTANCE: used for automatic control of the production process of gas transportation, for example, for monitoring and controlling a block of electric valves on sections of gas pipelines located in hard-to-reach areas. The system contains a measuring instrument unit 3, transmitting and receiving equipment 6, a power source 2, a central control unit 7 with a recording device 10, an electric valve unit 4 and a microprocessor controller 5. The power source 2 is an autonomous combined one, consisting of a battery and a vortex tube with a thermal transducer 11. The battery is connected to a measuring instrument unit 3, a radio modem 6 and a microprocessor controller 5. A vortex tube with a thermal transducer 11 is placed inside the pipeline in front of the electric valve assembly 4 and is connected to the measuring instrument assembly 3, while a temperature-reducing element 13 is installed on the cold flow diaphragm pipe of the vortex tube 11, which lowers the temperature based on the electrocaloric effect.

EFFECT: increasing the efficiency of control, reliability of operation and ensuring safe operation of the pipeline.
