Problems solved by technology
The existing three-way pipe fitting structure with different diameters, the main pipe mouth and the branch pipe mouth are connected at right angles, so the strength at the corner is relatively poor, and the work reliability is low
In addition, the existing three-way pipe fittings with different diameters do not have any heating effect. Under the condition of low temperature, the liquid in the three-way pipe fittings is easy to freeze into ice, which shortens the service life of the three-way pipe fittings and greatly reduces the working time of the three-way pipe fittings. reliability

Embodiment Construction
[0008] Hereinafter, the present invention will be further explained in conjunction with the drawings in the specification.
[0009] As shown in the figure, an antifreeze reducing tee copper pipe fitting includes a tee main pipe 1 and a branch pipe 2, a transition pipe 3 and a tapered pipe 4 are set between the tee main pipe 1 and the branch pipe 2, and the transition pipe 3 and the tee main pipe 1 is vertical, one end of the transition pipe 3 is connected to one side of the pipe wall of the tee main pipe 1, the large diameter end of the tapered pipe 4 is connected to the other end of the transition pipe 3, and the small diameter end of the tapered pipe 4 is connected to the branch pipe 2, and the tee main pipe 1. The inner holes of transition pipe 3, tapered pipe 4 and branch pipe 2 are connected. The inner wall of the three-way main pipe 1 is fixedly provided with a first heating bar 5 along the length direction, and a heating wire is provided in the first heating bar 5. The in...

The invention discloses an anti-freezing reducer tee copper pipe fitting, and belongs to the technical field of pipe fittings. The anti-freezing reducer tee copper pipe fitting comprises a three-way main pipe and a branch pipe, wherein a transition pipe and a conical pipe are arranged between the three-way main pipe and the branch pipe; the transition pipe and the three-way main pipe are perpendicular to each other; one end of the transition pipe is connected to one side of the pipe wall of the three-way main pipe; the large-diameter end of the conical pipe is connected with the other end of the transition pipe; the small-diameter end of the conical pipe is connected with the branch pipe; inner holes of the three-way main pipe, the transition pipe, the conical pipe and the branch pipe are communicated; the inner wall of the three-way main pipe is fixed with a first heating strip in the length direction; and a heating wire is arranged in the first heating strip. The reducer tee pipe fitting is simple in structure and reasonable in design; the three-way main pipe and the branch pipe are connected through the transition pipe and the conical pipe, so that the connecting part strength is improved; and the heating strip is arranged for achieving the buffer effect and improving the anti-freezing performance.
Description
Technical field [0001] The invention belongs to the technical field of pipe fittings, and specifically relates to an antifreeze reducing three-way copper pipe fitting. Background technique [0002] Three-way pipe fittings are widely used in refrigeration accessories. In the existing reduced-diameter three-way pipe fitting structure, the main pipe port and the branch pipe port are connected at right angles, so the corner strength is relatively poor and the working reliability is low. In addition, the existing reducing tee fittings do not have any heating effect. Under low temperature conditions, the liquid in the tee fittings is easy to freeze into ice, which shortens the service life of the tee fittings and greatly reduces the working time of the tee fittings. reliability. Summary of the invention [0003] In view of the problems existing in the prior art, the purpose of the present invention is to design and provide a technical solution for antifreeze reducing three-way copper ...
