The core body 20 The first end of the core body 20 is threadedly connected with the branch pipe body 10, and the second end of the core body 20 is used for press-tight connection with the pipe material. Specifically, as shown in FIGS. 2 and 3 , the branch pipe body 10 may be a Y-shaped three-way branch pipe with an oblique angle of 45° or 90°. In this embodiment, the outer wall of the branch pipe body 10 is provided with an arrow indicator 160 for indicating the flow direction, which is convenient for observation and operation. The pore diameter of the main flow hole 110 is larger than the pore diameter of the flow distribution hole 120 , thereby effectively ensuring the performance of flow rate and pressure of the flow distribution hole 120 and meeting the use requirements of the flow distribution hole 120 .

In the above-mentioned branch pipe, the first end of the core body 20 is threadedly connected to the branch pipe body 10, and the second end of the core body 20 is connected to the pipe material by pressing and sealing, and the core body 20 is connected to the pipe by pressing and sealing. Instead of the traditional welding method, the branch pipe does not need to be welded during on-site installation, the installation is fast and efficient, the installation process requirements are low, and the product cost is low. Traditionally, the material of the branch pipe body is copper pipe to ensure the welding performance. The branch pipe described in this embodiment is connected to the pipe material by pressing and sealing. The material of the branch pipe body does not need to use copper pipe, but copper pipe can be used. The cost of the product is affordable, and it can be used in a wide range of fields, such as air-conditioning pipelines, gas pipelines, drinking water pipelines and other fields. In addition, the first end of the core body 20 is threadedly connected to the branch pipe body 10. When the branch pipe needs to be matched with pipes of different calibers, the core body 20 and the branch pipe body 10 only need to be disassembled and replaced with corresponding standard ones.
