Embodiment Construction
[0017] Such as figure 1 , figure 2 and image 3 As shown, an integrated spherical multi-way pipe fitting is characterized in that it includes a main pipe 1 and a branch pipe 2, the upper half of the main pipe 1 is a circular straight pipe 1.1, and the lower half of the main pipe 1 is a hemispherical cylinder 1.2, the diameter of the circular straight tube 1.1 is equal to the diameter of the hemispherical cylinder 1.2; the three branch pipes are integrally formed on the hemispherical cylinder 1.2 of the main pipe 1, and the branch pipes 2 are uniformly distributed on the hemispherical cylinder 1.2. The angle α between the branch pipes 2 is 90°.
[0018] Such as Figure 4 As shown, the stamping die includes a die base 11 and a punch 12. A punching hole 11.1 is provided in the die base 11. The upper part of the punching hole 11.1 is cylindrical, and the bottom of the punching hole 11.1 is hemispherical. On the hemispherical mold base 11 Three hydraulic through-holes 11.2 are...

The invention relates to an integrated spheroidal multi-pass pipe fitting which is characterized by comprising a main pipe and branch pipes. The upper half section of the main pipe is a circular straight pipe barrel; the lower half section of the main pipe is a hemispherical barrel; the diameter of the circular straight pipe barrel is equal to the diameter of the hemispherical barrel; the 2 to 4 branch pipes are integrally arranged on the hemispherical barrel of the main pipe and are circumferentially and uniformly distributed on the hemispherical barrel; and an included angle alpha between each two branch pipes is 90 to 120 degrees. The invention further relates to a preparation method of the integrated spheroidal multi-pass pipe fitting. The integrated spheroidal multi-pass pipe fittingand the preparation method thereof provided by the invention have the advantage of capability of improving the quality reliability of the multi-pass pipe fitting.
Description
technical field [0001] The invention relates to a multi-way pipe fitting, in particular to an integrated spherical multi-way pipe fitting and a preparation method thereof. Background technique [0002] Multi-way pipe fittings are special pipe fittings, which are used to distribute and transport the medium of the main pipeline to multiple branch pipelines, and can also centrally transport multiple pipelines to one main pipeline. Commonly used are positive tee, Y-shaped tee, cross and manifold. The branch pipes of existing multi-way pipe fittings are all welded, the weld seam stress is concentrated, and leakage is easy to occur. The quality and reliability of multi-way pipe fittings are poor. Contents of the invention [0003] In view of the above disadvantages, the object of the present invention is to provide an integrated spherical multi-way pipe fitting which can improve the quality and reliability of the multi-way pipe fitting. [0004] The technical content of the pre...
