| description | The utility model relates to the technical field for the detection of an oil pipeline, in particular to a leakage detecting device for an internal oil-gas pipeline. The leakage detecting device consists of two parts, i.e. a docking mechanism and a detecting mechanism, wherein the docking mechanism comprises a flange plate, a piston cylinder, a piston, a base plate and a cover plate; and the detecting mechanism is formed by the means that two sets of infrasonic wave piezoelectric sensors are connected with a piezoelectric detector by a conductive electrode plate between the two sets of infrasonic wave piezoelectric sensors. As the leakage detecting device adopts a mature infrasonic wave piezoelectric sensing technology and the specific docking mechanism, the infrasonic wave generated by the leakage of liquid in the pipeline is directly fed back to the piezoelectric sensors in the pipeline through an oil-gas medium in the pipeline, so that the problem of an external pipeline wall sound wave detecting technology |
