FIELD: machine building. ^ SUBSTANCE: automatic system of detection and insulation of leaks in pipeline for fluid medium consists of pipeline section for fluid medium flow. It has an internal section for fluid medium flow and a coupling coaxially arranged with the internal section, also it has an enveloping internal section, closed at each end of the pipeline section and filled with operating fluid under pressure. Further, the automatic system has a device for detection of working fluid pressure drop; this device is installed in the pipeline section and indicates there is a leak from the pipeline section or inside it; the automatic system is equipped with a shut off facility for one end of the pipeline section; when the device detects pressure drop of working fluid, the facility is actuated and it shuts off one end of the pipeline section. ^ EFFECT: improvement of procedure. ^ 20 cl, 7 dwg |
