Abstract

The invention discloses a pipeline plugging device. The pipeline plugging device comprises a plugging rod; one end of the plugging rod is provided with a seal board; the outer circumference of the plugging rod is provided with an annular groove; an annular seal ring is arranged in the annular groove; the outer side of the annular seal ring is higher than the outer circumference of the plugging rod. According to the pipeline plugging device, the annular seal ring is arranged in the annular groove; the outer side of the annular seal ring is higher than the outer circumference of the plugging rod. When the pipeline plugging device is used, the annular seal ring makes tight contact with the inner wall of a pipeline, and the plugging effect is good. Meanwhile, the outer side of the seal board is provided with a pulling head, so that the plugging rod can be pulled out of the pipeline conveniently. The pipeline plugging device is simple in structure and easy to manufacture.

Description

A kind of pipeline plug
Technical field
The present invention relates to a kind of improvement of pipe plugging, refer in particular to a kind of simple in structure, make the pipeline plug simple, that plugging effect is good.
