Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

As shown in fig. 1, a special water pipe repair pipe connector comprises at least two outer pipes 1 and inner pipes 2 which are sleeved with each other, wherein a trumpet-shaped connector 3 is arranged at the outer end of the outermost outer pipe 1, the trumpet-shaped connector 3 is sleeved with the outer side of an upstream pipe to be connected, a first sealing groove 31 is arranged on the inner wall of the trumpet-shaped connector 3, a first sealing ring 32 is arranged in the first sealing groove 31, and the first sealing ring 32 is in abutting seal with the outer surface of the upstream pipe to be connected;

the outer end of the innermost inner pipe 2 is provided with a conical connector 4, the conical connector 4 is inserted into the inner side of a pipeline to be connected at the downstream, a second sealing groove 41 is arranged outside the conical connector 4, a second sealing ring 42 is arranged in the second sealing groove 41, and the second sealing ring 42 is in abutting seal with the inner surface of the pipeline to be connected at the downstream; the outer sides of the outer pipes 1 of two adjacent pipelines are provided with male threads 5, and the inner sides of the inner pipes 2 of two adjacent pipelines are provided with female threads 51 which are matched and connected with the male threads 5.

Rivers treat from the upper reaches that the takeover says that the flow is to treating the takeover way to the lower reaches, rivers in the water pipe adapter are from outer tube 1 flow direction inner tube 2, loudspeaker form interface 3 and conical interface 4's setting, can avoid rivers to take place the risk of leaking in joint gap department when water pipe adapter and treat the takeover way junction, also avoid rivers to produce the impact force to the water pipe adapter, the connection stability and the sealed effect of water pipe adapter and treatment takeover way have been guaranteed, moreover, the steam generator is simple in structure, high durability and convenient installation, and low maintenance cost.
