Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
Examples
As shown in fig. 1-3, a novel external pressure type non-excavation pipeline repair hose special joint, including connecting body 8, sealed staple bolt 6 and keeping apart anti-skidding staple bolt 7 triplex, is equipped with flexible isolation cover 10 in the connecting body 8, is equipped with flexible hose 4 between flexible isolation cover 10 outer wall and the inner wall, connects 8 one side of body and is equipped with in proper order and keeps apart anti-skidding staple bolt 7 and sealed staple bolt 6.
Preferably, the joint body 8 provided with the flexible isolation sleeve 10 and the flexible hose 4 is arranged on the pipeline 5 to be repaired between the original pipelines 1.
Preferably, the joint body 8 is provided with an anti-slip groove 13 and a sealing groove 12, respectively.
Preferably, the original pipeline 1 and the pipeline 5 to be repaired are both provided with connecting flanges 11.
Preferably, one side of the original pipeline 1, which is provided with the connecting flange 11, is fixedly connected with one side of the joint body 8, which is provided with the connecting flange 11, through the connecting bolt 3 and the nut 2, and a sealing ring 9 is arranged between the two connecting flanges 11.
Preferably, the side of the pipeline 5 to be repaired, which is provided with the connecting flange 11, is connected with the sealing hoop 6 arranged at one end of the joint body 8 through the connecting bolt 3 and the nut 2, and the sealing ring 9 is arranged between the sealing hoop 6 and the connecting flange 11 arranged at one side of the pipeline 5 to be repaired.
Preferably, the isolation anti-skid anchor ear 7 and the sealing anchor ear 6 are divided into three equal parts by linear cutting.
Preferably, a flexible hose 4 sleeving groove is arranged between the outer wall and the inner wall of the flexible isolation sleeve 10.
The joint is composed of a joint body, a sealing hoop and an isolating anti-slip hoop.
