Reliability and Quality of Complex Systems
Background. Prolonged operation of shut-off valves of main gas pipelines leads to gradual wear of the sealing elements of ball valves and valves and a violation of their tightness. Timely detection of leakage of the shut-off valves at an early stage allows you to keep the equipment in working condit...

| description | Background. Prolonged operation of shut-off valves of main gas pipelines leads to gradual wear of the sealing elements of ball valves and valves and a violation of their tightness. Timely detection of leakage of the shut-off valves at an early stage allows you to keep the equipment in working condition and avoid the consequences caused by large volumes of gas leaks. A study of the parameters of the acoustic emission signal of a gas leak has been conducted, the results of which can be applied in the practical implementation of methods for diagnosing shut-off valves to detect gas leaks in case of violation of its tightness. Materials and methods. A simulation of a gas leak through a shut-off valve on a laboratory bench was carried out to simulate a leak. A description of the laboratory stand and a block diagram of a device for recording and analyzing the spectrum of the acoustic emission signal of a gas leak are given. Results and conclusions. The frequency spectra of the acoustic emission signal of a gas leak, taken on a laboratory stand, at various leakage volumes are presented. The measurement results are analyzed, conclusions are drawn about the criteria fordetermining the leakproofness of the shut-off valves according to the frequency spectrum of the acoustic emission signal of the leak. |
