Abstract
Tire tube air-inflating formula plugging apparatus for pipe end.Belong to capital construction field, oil field.It solve and utilize iron sheet point to be welded in pipe end at present to there is poorly sealed, easy loss as temporary plugging device, destroy the problem of groove.This tire tube air-inflating formula plugging apparatus for pipe end comprises circular dunnage, the peripheral curved of dunnage has annular groove, is provided with cavity in dunnage; Annular groove is embedded with the inflatable inner tube of annular, and inflatable inner tube is connected with charging air inlet, and the end of charging air inlet is positioned at cavity, and on the sidewall of cavity, the position of corresponding charging air inlet end has through hole.There is good sealing effect, life cycle length, safe and reliable advantage.
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 iron point.This mode is poorly sealed on the one hand, is easy to stolen on the other hand, easily destroys groove simultaneously, affect construction quality.
Summary of the invention
The purpose of this utility model utilizes iron sheet point to be welded in pipe end at present to there is poorly sealed, easy loss as temporary plugging device, destroy the problem of groove to solve, and provide a kind of tire tube air-inflating formula plugging apparatus for pipe end.
This tire tube air-inflating formula plugging apparatus for pipe end comprises circular dunnage, the peripheral curved of dunnage has annular groove, is provided with cavity in dunnage; Annular groove is embedded with the inflatable inner tube of annular, and inflatable inner tube is connected with charging air inlet, and the end of charging air inlet is positioned at cavity, and on the sidewall of cavity, the position of corresponding charging air inlet end has through hole.
The utility model has following beneficial effect:
The dunnage of this tire tube air-inflating formula plugging apparatus for pipe end plays a supportive role, and material can select glass fibre reinforced plastics, and inflatable inner tube is provided with charging air inlet.In pipe-line construction construction, after pipeline welding, utilize this tire tube air-inflating formula plugging apparatus for pipe end as temporary plugging.The tire tube air-inflating formula plugging apparatus for pipe end of respective model is selected according to internal diameter of the pipeline, put the inflatable inner tube of unaerated into the mouth of pipe together with dunnage, then utilize air pump to tire tube air-inflating, until inner tube of a tyre tensioner internal wall of pipe orifice, whole tube opening is sealed, the good charging air inlet of last shutoff.Owing to adopting the sealing means of inflation/deflation, thus reusable, extend its working life.Because this tire tube air-inflating formula plugging apparatus for pipe end is placed in pipeline, thus tube groove can not be destroyed.Can tensioner internal wall of pipe orifice after the inflation of tire tube air-inflating formula plugging apparatus for pipe end, compared with existing temporary plugging device, there is good sealing effect, advantage that life cycle is long, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-dunnage; 2-annular groove; 3-cavity; 4-inflatable inner tube; 5-charging air inlet; 6-through hole; 7-pipeline.
Embodiment
Below in conjunction with Fig. 1, the utility model is described further:
This tire tube air-inflating formula plugging apparatus for pipe end comprises circular dunnage 1, and dunnage 1 plays a supportive role, and material can select glass fibre reinforced plastics, for alleviating the weight of dunnage 1, can adopt hollow structure.The peripheral curved of dunnage 1 has annular groove 2, cavity 3 is provided with in dunnage 1, annular groove 2 is embedded with the inflatable inner tube 4 of annular, inflatable inner tube 4 is connected with charging air inlet 5, charging air inlet 5 can adopt common unidirectional charging air inlet, the end of charging air inlet 5 is positioned at cavity 3, on the sidewall of cavity 3, the position of corresponding charging air inlet 5 end has through hole 6, adopt said structure, charging air inlet 5 end is hidden in cavity 3, both charging air inlet 5 effectively can have been prevented to be subject to artificial destruction, can to have prevented again non-workmen from being pulled out by force by plugging device by pulling charging air inlet 5.In pipe-line construction construction, pipeline 7 utilizes this tire tube air-inflating formula plugging apparatus for pipe end as temporary plugging after welding.The tire tube air-inflating formula plugging apparatus for pipe end of respective model is selected according to pipeline 7 internal diameter, put the inflatable inner tube 4 of unaerated into the mouth of pipe together with dunnage 1, then utilize air pump to tire tube air-inflating, until inner tube of a tyre tensioner internal wall of pipe orifice, whole tube opening is sealed, the good charging air inlet 5 of last shutoff.Can tensioner internal wall of pipe orifice after the inflation of tire tube air-inflating formula plugging apparatus for pipe end, compared with existing temporary plugging device, there is good sealing effect, advantage that life cycle is long, safe and reliable.
