Description
Technical field
The present invention relates to a kind of cast-iron pipe repair apparatus and method, belong to cast-iron pipe repairing technique field.
Background technology
Enterprise is during civil engineering, and construction party is not known and the reason such as misoperation to underground cast-iron pipe position,
Underground cast-iron pipe rupture leak can be caused.In pipe leakage, site operation is unable to advance to perfect order, and enterprise's part producing is impacted
In the case of it is necessary to possessing the technology quickly repaired to cast-iron pipe.At present, used normal is repaired to cast-iron pipe
Rule method is electric welding, and due to having water in pipeline and having certain hydraulic pressure, this operating method does not possess operating environment and condition of work, do not had
There is feasibility.
The content of the invention
To overcome the deficiency of prior art, the present invention provides a kind of cast-iron pipe repair apparatus and method.
The present invention is realized by following technical proposal：A kind of cast-iron pipe repair apparatus, including sleeve pipe, are fixedly installed on set
The ring flange at pipe two ends, and it is arranged on the snap ring of inside pipe casing.
The snap ring is the ring for being attached at internal surface of sleeve pipe.
The internal diameter of the snap ring is more than the external diameter 2mm of repairing pipes to be repaired.
The snap ring is two, each one of head and the tail.
5~the 10mm of diameter for being directly more than repairing pipes to be repaired of described sleeve pipe.
Another object of the present invention is to provide a kind of cast-iron pipe method for repairing and mending, using above-mentioned repair apparatus, under
Arrange each step：
（1）In the case where not influenceing industrial water, reduce flow, reduce the hydraulic pressure of repairing pipes to be repaired；
（2）Cut the damaged section of repairing pipes to be repaired, it is ensured that the mouth of pipe is smooth, be respectively inserted on two parts of remaining repairing pipes to be repaired
One loose flange；
（3）Repair apparatus is arranged on step（2）Repairing pipes to be repaired on, make repairing pipes to be repaired two parts be placed in repairing dress
In the sleeve pipe put, by snap ring clamping；
（4）Gap location between repair apparatus and repairing pipes to be repaired inserts filler, it is ensured that liquid in pipe no longer oozes out, then uses
Bolt fixes loose flange with ring flange, compresses filler, that is, completes the repairing to pipeline to be repaired.
The step（2）The size of loose flange matched with the ring flange of repair apparatus, and enable loose flange in pipe
Smoothly moved on road.
The step（4）Filler be asbestos cord.
The advantage that the present invention possesses：The present invention is using the method for repairing and mending for installing repair apparatus additional, and in underground, cast-iron pipe ruptures
During leak, in the case where not possessing electric welding repairing condition, the Rapid-Repair to broken pipe can be realized.Method letter involved in the present invention
Single practical, used parts are market purchase material, it is only necessary to routinely machining, non-standard fabrication and installation.This hair
Bright that quickly cast-iron pipe can be repaired, the present invention is with method is simple and easy to apply, simple in construction, installation operation is convenient, investment
Expense is low, safe and practical, can reduce the advantage of cast-iron pipe repairing time, compensate for the shortcoming of electrical welding operation environment limitation,
It is widely used in the repairing of various cast-iron pipes.
Brief description of the drawings
Fig. 1 is the structural representation of cast-iron pipe repair apparatus；
Fig. 2 is embodiment step（2）Operation chart；
Fig. 3 is structural representation of the completion to the repairing of pipeline to be repaired.
Embodiment
With reference to embodiment and accompanying drawing 1-3, the present invention will be further described.
As illustrated, cast-iron pipe repair apparatus includes sleeve pipe 1, the ring flange 2 at the two ends of sleeve pipe 1 is fixedly installed on, and
It is arranged on the snap ring 3 inside sleeve pipe 1；The snap ring 3 is the ring for being attached at the inwall of sleeve pipe 1；Snap ring 3 is two, head and the tail each one
It is individual.5~the 10mm of diameter for being directly more than repairing pipes to be repaired of sleeve pipe.
Using the cast-iron pipe method for repairing and mending of above-mentioned repair apparatus, by following each step：
（1）In the case where not influenceing industrial water, reduce flow, reduce the hydraulic pressure of repairing pipes to be repaired；
（2）Cut the damaged section 5 of repairing pipes 4 to be repaired, it is ensured that the mouth of pipe is smooth, it is each on two parts of remaining repairing pipes 4 to be repaired
It is inserted in a loose flange 6；The size of loose flange 6 is matched with the ring flange 2 of repair apparatus, and enables loose flange 6 in pipe
Smoothly moved on road；
（3）Repair apparatus is arranged on step（2）Repairing pipes to be repaired 4 on, make repairing pipes 4 to be repaired two parts be placed in repairing
In the sleeve pipe 1 of device, by the clamping of snap ring 3；
（4）Gap location between repair apparatus and repairing pipes to be repaired 4 inserts the asbestos cord of filler 7, it is ensured that liquid in pipe is no longer
Ooze out, then fixed loose flange 6 with ring flange 2 with bolt 8, compress the asbestos cord of filler 7, that is, complete to pipeline 4 to be repaired
