Detailed Description
The embodiments of the present invention will be described in more detail with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the embodiments of the present invention after studying the specification. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
The utility model provides a composite pipeline connecting structure as shown in fig. 1-2, which comprises a connecting ring 1 arranged between the pipe walls of two sections of pipelines, wherein a tubular part 2 extending towards the pipelines 5 on two sides is arranged on the inner side of the connecting ring 1, inner sealing parts 3 are arranged between the tubular part 2 and the pipelines 5 on two sides, and an outer reinforcing layer 4 for sealing the two sections of pipelines 5 and the connecting ring 1 is arranged on the outer side of the connecting ring 1.
The connecting ring may be integrally formed with the tubular member and made of stainless steel or other metal. The tubular member at one side of the connecting ring can be inserted into the inner wall of one end of one pipeline, the connecting ring is clamped on the side wall of the end port of the pipeline to play a role in limiting and fixing, and the other pipeline is inserted into the tubular member at the other side of the connecting ring, so that the installation is rapid and convenient. The inner sealing piece is used for enhancing the sealing performance between the tubular piece and the pipeline, the outer strengthening layer is used for sealing the connection part of the two pipelines and the outer side of the connecting ring, the secondary sealing and the protection effect on the pipeline connection structure are achieved, and the structural strength and the rigidity of the pipeline connection structure after butt joint are guaranteed.
Preferably, the inner seal 3 is an O-ring and the tubular element 2 is provided with a groove for fixing the O-ring. The O-shaped sealing ring can be an O-shaped rubber sealing ring which meets the national standard of rubber sealing pieces for domestic drinking water pipeline systems.
Preferably, at least two inner seals 3 are provided between the tubular member 2 and one side duct.
Preferably, the outer reinforcing layer 4 is a resin cement layer covering between two sections of pipelines. The resin daub layer can adopt epoxy resin daub, and has excellent durability, impermeability, compactness and bonding force, strong waterproof and anticorrosion effects and excellent mechanical property.
The foregoing is a detailed description of one or more embodiments of the utility model, which is set forth in more detail and is not intended to limit the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the spirit of the utility model, which falls within the scope of the utility model. Therefore, the protection scope of the present patent shall be subject to the appended claims.
