Description
Technical field
The utility model relates to the interim blocking technology of pipeline construction, particularly is a kind of pipeline plug.
Background technique
In the pipeline construction process, as not constructing continuously, its pipeline opening is wanted interim shutoff.The weldering one interim blind plate that has slices off with air gun during construction again, and workload is big.Clog like the soft thing of careless usefulness, easy entering pipelines such as dust, sandstone, rainwater influence the pipeline construction quality, can not meet the demands, and influence ordinary production.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned deficiency, designs a kind of pipeline plug.
The purpose of the utility model is realized by following technical proposals:
The utility model comprises: capping, interior side's wrench, center-pole, right-hand thread silk braid, hinge, connecting rod, lock dog, left-hand thread silk braid.The capping of its pipeline plug is the channel portion disc structure, and the center is provided with circular countersunk head through hole, and center-pole passes from the countersunk head through hole, is installed in the countersunk head through hole with interior side's wrench of center-pole one; Upper and lower right-handed thread, the left-hand thread screw thread of being respectively equipped with of center-pole connecting right-hand thread silk braid and left-hand thread silk braid, and right-hand thread silk braid and left-hand thread silk braid are respectively equipped with plural hinge, and the hinge on hinge and connecting rod, connecting rod and the lock dog is hinged, and lock dog is provided with the card tooth.
The beneficial effect of the utility model is: the pipeline opening shutoff is tight, and is solid and reliable, easy to loading and unloading, is applicable to the interim shutoff of big or small pipeline construction, improves construction quality, and has the antitheft effect.
