METHOD TO DIAGNOSE TIGHTNESS OF STOP PIPELINE VALVES GATE AND DEVICE FOR ITS REALISATION Russian patent published in 2013 - IPC F16K37/00 G01M3/28 

FIELD: construction.

SUBSTANCE: feature of methods and devices according to the first and section versions is the fact that in devices, through which methods are realised, an autonomous pressure source (compressor) is used. A testing substance from a compressor (air under excessive pressure) fills cavities of diagnosed valves and simultaneously acts at functional blocks via a pressure sensor for implementation of continuous automatic registration of measurements in an analogue mode with simultaneous issue of results. The feature of the method and devices according to the third and fourth versions is the fact that in devices, via which the methods are implemented, there is no autonomous pressure source - a compressor, and the testing substance for valves diagnostics is a medium in the pipeline, on which the diagnosed valves are operated. The testing substance fills cavities of the diagnosed valves and simultaneously acts at functional blocks via pressure sensors, which implement continuous automatic registration of measurements in an analogue mode with simultaneous issue of results on tightness of a gate of stop pipeline valves.

EFFECT: reduced repair cycle of operated pipeline valves.
