Description
Technical Field
The utility model relates to the field of electric melting pipe fittings, in particular to an electric melting three-way joint with a heat dissipation structure.
Background
The electric melting pipe fitting is an electric melting connection, generally called electric melting welding, and is one of main connection parts in installation and construction of polyethylene plastic gas pipelines, and in the gas pipeline connection, an electric melting reducing tee joint is needed to fixedly connect multiple pipelines together. When the electric melting three-way joint is subjected to electric melting welding, in order to avoid the influence of the temperature of a welding interface and the surface of a pipe wall on the welding quality, the welding of the next section can be carried out after the cooling of the joint of the previous section is waited, in the prior art, in order to accelerate the cooling effect, the cooling is carried out by bubble water, and the cooling mode easily causes the phenomena of uneven internal crystallization, large internal stress and unsatisfactory tensile yield stress.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an electric melting three-way joint with a heat dissipation structure.
The technical scheme of the utility model is as follows: the utility model provides an electric smelting three way connection with heat radiation structure, is including being responsible for and the branch pipe, the branch pipe link up with being responsible for, be responsible for both ends and be responsible for to be connected by the heavy-calibre person in charge and small-calibre person in charge respectively and form, the branch pipe is formed by small-calibre branch pipe and heavy-calibre branch union coupling, the small-calibre person in charge is in charge of and is equallyd divide with the heavy-calibre branch pipe, the one end that is close to the branch pipe on the heavy-calibre person in charge inner wall is equipped with electric heating wire, the length direction evenly distributed who is responsible for along the heavy-calibre on the outer wall that the heavy-calibre was responsible for has a plurality of radiating groove, still be equipped with the inserting groove on the outer wall that the heavy-calibre was responsible for, be provided with the terminal of being connected with electric heating wire in the inserting groove.
According to a further technical scheme, the insertion groove is arranged perpendicular to the direction of the branch pipe.
Further technical scheme, the last fixed dustproof stopper that is provided with of inserting groove, the size of dustproof stopper and inserting groove's aperture phase-match.
The utility model has the beneficial effects that: the radiating grooves are formed in the outer wall of the large-diameter main pipe, the radiating rate of natural radiation of the connecting part is enhanced by increasing the radiating area of the electric-fusion welding part, and the radiating effect is better.

Detailed Description
The utility model will be further illustrated and understood by the following non-limiting examples.
As shown in fig. 1, the utility model provides an electric melting three-way joint with a heat dissipation structure, which comprises a main pipe 1 and a branch pipe 2, wherein the branch pipe 2 is communicated with the main pipe 1, two ends of the main pipe 1 are respectively formed by connecting a large-caliber main pipe 11 and a small-caliber main pipe 12, the branch pipe 2 is formed by connecting a small-caliber branch pipe 21 and a large-caliber branch pipe 22, the small-caliber main pipe 12 and the large-caliber branch pipe 22 have the same diameter, the production is convenient, the small-caliber branch pipe 21 can be formed by drawing after heating, and the production repeatability is good.
One end that is close to branch pipe 2 on the heavy-calibre is responsible for 11 inner walls is equipped with electric heating wire, and it has a plurality of radiating groove 13 to be responsible for the length direction evenly distributed of 11 along the heavy-calibre on the outer wall of 11 is responsible for to the heavy-calibre, still is equipped with inserting groove 3 on the outer wall of 11 is responsible for to the heavy-calibre, is provided with the terminal 31 of being connected with electric heating wire in inserting groove 3. The inserting groove 3 is perpendicular to the direction of the branch pipe 2, a dustproof plug 32 is fixedly arranged on the inserting groove 3, and the size of the dustproof plug 32 is matched with the aperture of the inserting groove 3. Through the arrangement, the water and dust prevention in the inserting groove 3 is ensured. The heat dissipation groove 13 is formed in the outer wall of the large-diameter main pipe 11, the heat dissipation rate of the joint is enhanced by increasing the heat dissipation area of the fused welding position, and the large-diameter main pipe is suitable for popularization and use.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
