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
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.
Background technique
In prior art, the shutoff of pipeline, comprise the shutoff bar usually; One end of described shutoff bar is provided with shrouding; Described shutoff bar becomes coniform; Be provided with retreating-proof hangnail ring on the excircle of described shutoff bar; The plugging structure complexity of this structure, processed complex; For this reason, we researched and developed a kind of simple in structure, make the pipeline plug simple, that plugging effect is good.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of simple in structure, make the pipeline plug simple, that plugging effect is good.
For achieving the above object, the technical solution used in the present invention is: a kind of pipeline plug comprises the shutoff bar; One end of described shutoff bar is provided with shrouding; Be provided with annular groove on the excircle of described shutoff bar; Be provided with O-ring seal in described annular groove; The outside of described O-ring seal exceeds the outer peripheral surface of shutoff bar.
Preferably, the arranged outside of described shrouding has the promotion head.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Pipeline plug of the present invention, be provided with O-ring seal in described annular groove; The outside of described O-ring seal exceeds the outer peripheral surface of shutoff bar; During use, described O-ring seal and inner-walls of duct close contact, plugging effect is good; Simultaneously, the arranged outside of described shrouding has the promotion head, can conveniently the shutoff bar be extracted from pipeline; The present invention is simple in structure, makes simple.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The sectional view that accompanying drawing 1 is pipeline plug of the present invention;
Wherein: 1, shutoff bar; 2, shrouding; 3, promote head; 4, annular groove; 5, O-ring seal.
embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Pipeline plug of the present invention, be provided with O-ring seal in described annular groove; The outside of described O-ring seal exceeds the outer peripheral surface of shutoff bar; During use, described O-ring seal and inner-walls of duct close contact, plugging effect is good; Simultaneously, the arranged outside of described shrouding has the promotion head, can conveniently the shutoff bar be extracted from pipeline; The present invention is simple in structure, makes simple.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
