Description

Technical Field

[0001] The invention belongs to the technical field of electric fusion flange pipes and relates to an electric fusion flange structure. Background Art

[0002] Electric fusion connection involves pre-inserting a composite pipe into a plastic electric fusion fitting. A heating wire embedded in the fitting is then energized to generate heat. This process initially creates a melt on the fitting's inner surface, which then expands and fills the gaps between the pipe and fitting, eventually forming a melt on the pipe's outer surface. The two melts fuse together, cooling and forming a tight connection between the pipe and fitting. Under current technology, electric fusion flanges are a commonly used type of electric fusion fitting. However, most current electric fusion flanges suffer from poor internal structural strength during use, and their overall structure is prone to deformation after the electric fusion connection, making them less practical.

[0003] To overcome the shortcomings of the existing technology, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses an electric fusion flange pipe structure [application number: 202022799081.X], which includes a straight pipe, a flange, and a sealing gasket. The sealing gasket is attached to the right end face of the flange. The straight pipe is perpendicularly arranged at the left end of the flange. The outer surface of the straight pipe is provided with an energizing device perpendicularly. The energizing device is divided into a first energizing post and a second energizing post. The first energizing post is provided with a first copper pole inside, and the second energizing post is provided with a second copper pole inside. The first end of the heating resistance wire is wound around the first copper pole for electrical connection, and the end of the heating resistance wire is wound around the second copper pole for electrical connection. A waterproof cover is hinged above the energizing device. The waterproof cover is made of elastic rubber and has spaced protrusions on the inner side of the waterproof cover. The heating resistance wire is evenly laid inside the straight pipe and is electrically connected to the energizing device. However, during use, the internal structural strength of this solution is still poor. The overall structure is easily deformed after the electric fusion connection, which has the disadvantage of poor practicality. Summary of the Invention
