Description
Technical Field
The utility model relates to an electric smelting tubular product technical field especially relates to an electric smelting pipe fitting.
Background
When the connection of public pipelines such as buried, fuel gas and water supply and drainage and the construction under pressure are carried out, the traditional method is to seal the pipeline connection by lead or cement. The problems of the sealing structure are that the construction is complex, time and labor are wasted, and the sealing structure is easily corroded due to the influence of the environment, so that the sealing effect is influenced. At present, the more advanced mode adopts electric smelting pipe fitting, and electric smelting pipe fitting said is made by polyethylene sleeve, setting up terminal on the sleeve, the heating wire of coiling on the sleeve inner wall, and it is not hard up to have the terminal often in production and construction transportation to make electric smelting pipe fitting electrical property impaired or even inefficacy, lead to the problem production that the pipe fitting welding is not firm or can't weld, seriously influence pipe-line system's welding quality.
Therefore, a new technique is sought to solve the above problems.
Disclosure of Invention
The utility model aims at: an electrofusion pipe fitting is provided.
The utility model provides an electric smelting pipe fitting, electric smelting pipe fitting includes neck bush and main part, the main part surface is provided with two binding post, binding post includes wiring cavity and terminal, the terminal is located the wiring cavity, the terminal end of terminal is equipped with the spliced pole, the welding has the electric fuse in the spliced pole, the electric fuse twines outside the neck bush.
The wiring cavity and the main body are integrally formed, a cavity communicated to the inner bushing is formed in the lower portion of the wiring cavity, a spiral is arranged on the inner wall of the cavity, and the wiring terminal is connected with the wiring cavity through spiral threads.
The wiring cavity is provided with an upper cover, and the upper cover is fixedly connected with the wiring cavity in a screwing mode.
The main body is also provided with a hollow groove, and a temperature sensing color changing label is arranged in the hollow groove.
The temperature-sensing color-changing label is embedded with a transparent upper cover.
In the above technical scheme, compared with the prior art, the beneficial effect that reaches is: the wiring terminal is in spiral threaded connection with the wiring cavity, so that the connection is tight, and the looseness is avoided; the electric fuse is welded in the connecting column, so that the connection between the connecting column and the electric fuse is enhanced, and the connecting column is prevented from loosening; the wiring cavity is provided with the upper cover and connected in a screwing mode, so that the connectivity is enhanced, and dust is prevented from falling off; the main body is also provided with a hollow groove, and a temperature sensing color changing label is arranged in the hollow groove, so that the temperature can be sensed, and the damage to the pipe caused by overhigh temperature can be avoided; the empty groove is covered with a transparent upper cover, so that the temperature-sensing color-changing label can be prevented from being polluted, and the cleanness of the temperature-sensing color-changing label can be kept.
