Embodiment Construction
[0031] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0032] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

The invention discloses a small-resistance three-way water pipe which comprises a pipeline body and a side connecting pipe. The side connecting pipe comprises a side connecting section and a flaring section, the side connecting section is connected with the flaring section, and the diameter of the flaring section is larger than that of the side connecting section; and the flaring section and the pipeline body are seamlessly welded, so that the pipeline body communicates with the side connecting section. The three-way pipe is connected in a seamless welded manner of the flaring section and the pipeline body, negative pressure is reduced, bubbles at the corner are eliminated, the service life of the pipe is prolonged, meanwhile, noise can be reduced, and the problem that the negative pressure of water at the welding corner is very large is solved. The invention further discloses a manufacturing method of the small-resistance three-way water pipe. The pipeline body is machined to the required length according to the size; the side connecting pipe is machined to the required length according to the size; broaching is carried out on the end of the side connecting pipe, and the flaring section is generated; and the flaring section and the pipeline body are seamlessly welded.
Description
technical field [0001] The invention relates to the field of pipelines, in particular to a small-resistance three-way water pipe and a manufacturing method thereof. Background technique [0002] At present, the pipe joint with three openings is called a three-way pipe. Tee pipes are widely used in pipe networks for conveying liquids and gases. Due to the different conveying media, the material of the tee pipe is divided into: cast iron, cast steel, cast copper, cast aluminum, plastic, glass, etc. The metal tee has a main pipe and a branch pipe that is perpendicular to the main pipe and communicates with the main pipe on one side of the main pipe. A valve is installed at the corner where the outlet direction of the main pipe and the outlet direction of the branch pipe meet. The state is a structure that is mutually sealed with the inner wall of the lumen. [0003] But there are following defects in the existing three-way water pipe of metal material: [0004] Please refer...
