Abstract
The utility model relates to a pipeline plug device which comprises a plug rod. One end of the plug rod is provided with a sealing plate, the outer circumference of the plug rod is provided with an annular groove, an annular sealing ring is arranged inside the annular groove, and the outer side of the annular sealing ring is higher than the outer circumference plane of the plug rod. According to the pipeline plug device, due to the facts that the annular sealing ring is arranged inside the annular groove, and the outer side of the annular sealing ring is higher than the outer circumference plane of the plug rod, when the pipeline plug device is used, the annular sealing ring makes close contact with the inner wall of a pipeline, and the plugging effect is good. Meanwhile, the outer side of the sealing plate is provided with a pulling head, and therefore the plug rod can be pulled out of the pipeline conveniently. The pipeline plug device is simple in structure and easy to manufacture.
