The placement groove 10 is arranged on the bent portion 101, and the docking portion 102 is used to dock with an external pipe. The assembly portions 103 of the two half pipe bodies 1 cooperate to form a fastening section, and the external connection section 3 is located at one end of the threaded sleeve 2 away from the fastening section.

[0038] A sealing ring 4 is sleeved on the fastening section, and the threaded sleeve 2 is threadedly connected to the fastening section, so that the two half pipe bodies 1 are connected and fixed. The two half pipe bodies 1 are fastened and docked with each other by the threaded sleeve 2 to form a three-way shape.

[0039] Structures such as the half pipe body 1 and the threaded sleeve 2 are provided, so that the three-way pipe fitting can be disassembled and assembled, which is convenient for cleaning, especially the corners inside the three-way pipe fitting.

[0040] To improve the sealing performance of the assembly and docking of the two half pipe bodies 1 and prevent leakage, an airbag 12 is placed between the two placement grooves 10. The placement grooves 10 and the airbag 12 are both in a U shape. A connecting pipe 13 is placed between the two half grooves 11, and the connecting pipe 13 communicates with the airbag 12.

[0041] During actual use, the operator places the airbag 12 in the placement groove 10 of one of the half pipe bodies 1, and the connecting pipe 13 is located in the half groove 11 corresponding to the placement groove 10; then the other half pipe body 1 is brought close to and fits with the above-mentioned half pipe body 1. The two placement grooves 10 correspond to each other, and the two half grooves 11 correspond to each other, so that the airbag 12 and the connecting pipe 13 are clamped between the two half pipe bodies 1, and the assembly portions 103 of the two half pipe bodies 1 cooperate to form a fastening section; the sealing ring 4 is sleeved on the fastening section, and then the threaded sleeve 2 is docked with the fastening section. The threaded sleeve 2 is rotated to connect and fix the two half pipe bodies 1. The two half pipe bodies 1 are fastened and docked with each other by the threaded sleeve 2 to form a three-way shape. The threaded sleeve 2 presses on the sealing ring 4. The sealing ring 4 is provided to improve the sealing performance of the docking of the threaded sleeve 2 and the fastening section.

[0042] The airbag 12 is made of rubber material and has the ability to expand and deform; the connecting tube 13 is made of hard material, such as stainless steel, and when the two half-tube bodies 1 are connected and fixed, the connecting tube 13 is squeezed and fixed between the two half-tube bodies 1 and extends outward without deformation.

[0043] A piston block 16 is slidably provided inside the connecting tube 13, and a sealing gasket is provided between the piston block 16 and the inner wall of the connecting tube 13 to improve the sealing performance; a support plate 14 is fixedly connected to the inner wall of the connecting tube 13, and the support plate 14 is close to the airbag 12, and a spring 15 is fixedly connected to the support plate 14, and the end of the spring 15 away from the support plate 14 is fixedly connected to the piston block 16.

[0044] When the piston block 16 is pressed toward the support plate 14, the gas in the connecting tube 13 is pressed into the airbag 12, and the airbag 12 expands to achieve a sealing effect. During assembly, the airbag 12 is in an unsaturated state, which is convenient for the operator to place the airbag 12 in the placement groove 10 of one of the half tube bodies 1.
