Zusammenfassung:	The utility model relates to the technical field of mechanical parts, in particular to a double-layer three-way pipe fitting. The double-layer three-way pipe fitting comprises a three-way inner pipe, an elastic piece and a three-way outer pipe. Wherein the three-way inner pipe comprises a first pipeline and a second pipeline, and the middle position of the second pipeline is communicated with the first pipeline; the elastic pieces comprise the first elastic piece and the second elastic piece, the first elastic piece is arranged on the outer wall of the first pipeline in a sleeving mode, and the second elastic piece is arranged on the outer wall of the second pipeline in a sleeving mode. The three-way outer pipe comprises a third pipeline and a fourth pipeline, and the middle position of the fourth pipeline is communicated with the third pipeline; the third pipeline is connected to the first pipeline in a sleeving mode and tightly presses the first elastic piece, and the fourth pipeline is connected to the sec
