CONTROL GAS LEAK IN TRANSITION GAS PIPELINE THROUGH ROAD

摘要

The invention relates to the field of gas production industry and can be used to monitor the technical condition of the main pipelines (MG) during their passage through the road, railway tracks and electrified railways. The essence of the technical solutions lies in the fact that in a system comprising a protective case with exhaust candle uses several leakage sensors (control) gas (at least three) mounted on the nozzle pneumatically connected to exhaust candle. Wherein the nozzle has a connection for system calibration in field conditions. Control outputs are connected to an electronic unit that enables to determine the residual concentration of combustible gases in the exhaust candle. The presence of several in a system controller, periodically undergoing calibration at regular place, improves the reliability of gas leakage monitoring system in the transition across MG. 2 ZP f-ly; 2 yl.
