and a waterproof fluid filler is arranged in the space below the lifting ring in the filling cavity.

Preferably, the upper end surface of the fixed pipe is flush with the upper end surface of the lower pipeline.

Preferably, the fixed pipe positioned in the fixed cavity is in threaded connection with the inner wall of the fixed cavity, the outer end face of the connecting part is in threaded connection with the inner wall of the filling cavity, and the outer threads of the connecting part are in the same direction as the outer threads of the fixed pipe.

Preferably, the fixed tube diameter is the same as the connecting portion inner diameter, which is the same as the filling lumen inner diameter.

3. Advantageous effects

Compared with the prior art, the utility model has the advantages that:

(1) this scheme is through compressing intraductal filler when installing pipeline and lower pipeline, and then makes the filler be full of the thread clearance of junction and the mode in installation clearance, repairs and protects pipeline junction from inside, prevents that the junction of pipeline from producing after long-time the use and connecting not tightly and causing the leakage, leads to the wasting of resources, improves cost of maintenance.

Detailed Description

Referring to fig. 1-3, a pipeline joint repairing apparatus includes an upper pipeline 11, a lower pipeline 12, a connecting portion 13, a fixing pipe 16 and a lifting ring 17.

The upper pipeline 11 is arranged on the upper side of the lower pipeline 12, the axis of the upper pipeline is right opposite, the connecting portion 13 is fixedly arranged at the lower end of the upper pipeline 11, a filling cavity 14 is formed in the lower pipeline 12, a fixing cavity 15 is communicated with the lower side of the filling cavity 14, the fixing pipe 16 is arranged in the fixing cavity 15, the lifting ring 17 is sleeved outside the fixing pipe 16, a sliding gap is formed between the inner side of the lifting ring 17 and the outer end face of the fixing pipe 16, a sliding gap is formed between the outer end face of the lifting ring 17 and the inner wall of the filling cavity 14, and the sum of the thickness of the lifting ring 17 and the height of the connecting portion 13 is equal to the depth of the filling cavity 14.

A space in the filling chamber 14 below the lifting ring 17 is filled with a waterproof fluid filling.

The upper end surface of the fixed pipe 16 is flush with the upper end surface of the lower pipe 12.

The fixed pipe 16 in the fixed cavity 15 is in threaded connection with the inner wall of the fixed cavity 15, the outer end face of the connecting portion 13 is in threaded connection with the inner wall of the filling cavity 14, and the outer side threads of the connecting portion 13 are in the same direction as the outer side threads of the fixed pipe 16.
