Abstract
Clamp band type plugging apparatus for pipe end.Belong to capital construction field, oil field.It solve and utilize sheet metal point to be welded in pipe end to there is poorly sealed, easy loss as temporary plugging device and destroy the problem of groove.Be lined with steel wire in the plugging cap of this plugging device, the outer side wall of plugging cap is fixed with some positioning rings, all positioning rings are all positioned on the same cross section of plugging cap; Also comprise two shell rings with locking device, two shell rings are through positioning ring and symmetry is fixed on plugging cap, and the free end of every bar shell ring is through the locking device on another shell ring; Described locking device has screw, is connected with anti-theft screw in screw, the end of anti-theft screw contacts with the locking nut on locking device.The utility model has the advantages such as simple to operate, good sealing effect, good anti-theft effect, life cycle are long, safe and reliable.
Description
Technical field
The utility model belongs to capital construction field, oil field, is specifically related to a kind of plugging apparatus for pipe end.
Background technique
In engineering in pipeline, after pipeline welding, welding pipeline section for preventing ice and snow, ponding, dust etc. from entering, usually will install temporary plugging device additional at pipe end.At present, common type is for be welded in pipe end as temporary plugging device using a sheet metal point.This mode is poorly sealed on the one hand, is easy to stolen on the other hand, is easy to destroy groove simultaneously, affects construction quality.
Summary of the invention
The purpose of this utility model utilizes sheet metal point to be welded in pipe end to there is poorly sealed, easy loss as temporary plugging device and destroy the problem of groove to solve, and provide a kind of clamp band type plugging apparatus for pipe end.
This clamp band type plugging apparatus for pipe end comprises plugging cap, is lined with steel wire in plugging cap, and the outer side wall of plugging cap is fixed with some positioning rings, and all positioning rings are all positioned on the same cross section of plugging cap; Also comprise two shell rings with locking device, two shell rings are through positioning ring and symmetry is fixed on plugging cap, and the free end of every bar shell ring is through the locking device on another shell ring 5; Described locking device has screw, is connected with anti-theft screw in screw, the end of anti-theft screw contacts with the locking nut on locking device.
The utility model has following beneficial effect:
Plugging cap in use, is enclosed within the pipeline mouth of pipe by this clamp band type plugging apparatus for pipe end, then is tightened by the locking nut 7 on locking device, until plugging cap afterbody compresses pipeline mouth of pipe outer wall, is finally tightened by anti-theft screw again.In pipe-line construction construction, after pipeline welding, this clamp band type plugging apparatus for pipe end can be used as temporary plugging.During construction, the clamp band type plugging apparatus for pipe end of respective model can be selected according to outer diameter tube.Owing to eliminating welding step, thus substantially increase shutoff efficiency, alleviate the labor intensity of workman.Plugging cap adopts rubber to make simultaneously, not only long service life, and reusable.The utility model has the advantages such as simple to operate, good sealing effect, good anti-theft effect, life cycle are long, safe and reliable.
