Footpath is more than the internal diameter of the pipeline of described more Large Diameter Pipeline, and the bottom surface of described big capping has downwardly extended a cylinder boss, and its diameter is slightly
Less than the internal diameter of described positive round conical ring, the center of described big capping is machined with the through hole passed through for described screw rod, described locking plate
It is arranged in described large circle to compress described big capping and capping to the motion of described fixed disk so that described O diameter
Expand.
After using technique scheme, this utility model, compared with background technology, has the advantage that
1, directly plug is filled in the pipeline to be blocked, turn the knob on locking plate, just can make seal diameter
Expand and reliably seal up pipeline, when preserved pipeline used by needs, unscrew knob, i.e. can be taken off plug, then at provided pipe
Being socketed straight tube on road and use glue adhesive seal, whole polyvinyl chloride is efficient, it is not necessary to uses extra joint, reduces use
Cost and human cost, have high promotional value on low pressure pipeline；
2, possess the closure size of two kinds of different sizes, when reserved pipeline is the multiple-way duct that bore differs, need
During the switching of multiple pipeline enclosures, plug can be used flexibly to block according to the bore of wanted blocking pipe.
