PVC pipes and fittings are widely used in construction projects due to their lightweight, excellent chemical resistance, low flow resistance, and high mechanical strength. However, PVC tee fittings often rupture and leak during hydrostatic testing. A common method to improve the strength of these fittings is to increase the wall thickness, but this significantly increases costs. Utility Model Content

[0007] The present invention is further configured such that the axis of the first channel is perpendicular to the axis of the second channel.

[0008] The present invention is further configured such that the inner wall of the channel is provided with a stepped surface, which is perpendicular to the axis of the channel.

[0009] The present invention is further configured such that the second channel has a stepped surface, which is perpendicular to the axis of the second channel.

[0010] The present invention is further configured such that the extension tube is provided with a groove, the groove is located at the end of the extension tube away from the main body of the pipe, and the groove radially penetrates the inner wall of one side of the extension tube.

[0011] The present invention is further configured such that the trough is I-shaped.

[0012] The present invention is further configured such that a filling block is installed in the groove, and the filling block is inserted into the groove with an interference fit.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. The main body of the pipe fitting experiences the greatest stress at point P, making it most prone to cracking. The crack line runs along the dotted line K, which is parallel to the axis of the main body of the pipe fitting. By installing a second reinforcement section, the main body of the pipe fitting and the extension pipe are tightened, reducing the occurrence of cracking along the dotted line K.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1;

[0025] like Figures 1-2 As shown, this embodiment discloses a tee fitting, including a fitting body 1. The fitting body 1 includes an extension pipe 11, the axial direction of which is perpendicular to the axial direction of the fitting body 1. The extension pipe 11 extends along the outer wall of the fitting body 1 towards the side away from the fitting body 1. The fitting body 1 has a second channel 12, which axially penetrates the fitting body 1. The extension pipe 11 has a first channel 111, which axially penetrates the extension pipe 11. The second channel 12 and the first channel 111 are interconnected, and the axis of the first channel 111 is perpendicular to the axis of the second channel 12.

[0026] like Figure 2 As shown, the inner wall of the channel 111 is provided with a stepped surface 1111, which is perpendicular to the axis of the channel 111. When a connecting pipe is installed in the channel 111, the end face of the connecting pipe can abut against the stepped surface 1111 to achieve a seal.

[0027] like Figure 2 As shown, the second channel 12 is provided with a stepped surface 121, which is perpendicular to the axis of the second channel 12. When a connecting pipe is installed in the second channel 12, the end face of the connecting pipe can abut against the stepped surface 121 to achieve a seal.

[0028] like Figure 1 , Figure 2 As shown, the main body 1 of the pipe fitting is provided with a reinforcing part 13, which is located at the connection between the main body 1 of the pipe fitting and the outer wall of the extension pipe 11. The reinforcing part 13 is a ring-shaped structure and is arranged circumferentially along the extension pipe 11. The reinforcing part 13 is integrally formed with the main body 1 of the pipe fitting and the extension pipe 11 to increase the bonding strength between the main body 1 of the pipe fitting and the extension pipe 11 and reduce the occurrence of pipe breakage.

[0029] like Figure 1 As shown, the main body 1 of the pipe fitting also has a second reinforcing part 14, which is located on both sides of the extension pipe 11 in the axial direction, and the length direction of the second reinforcing part 14 is oriented towards the circumferential direction of the outer wall of the main body 1 of the pipe fitting. The second reinforcing part 14 is connected to the outer wall of the extension pipe 11, the first reinforcing part 13, and the outer wall of the main body 1 of the pipe fitting. The main body 1 of the pipe fitting, the extension pipe 11, the first reinforcing part 13, and the second reinforcing part 14 are integrally formed. According to the finite element analysis, the stress of the main body 1 of the pipe fitting is the greatest at point P, and it is most prone to cracking, and the crack line is along... Figure 1 The dashed line K is parallel to the axis of the main body 1 of the pipe fitting. By setting the second reinforcement part 14, the second reinforcement part 14 tightens the main body 1 of the pipe fitting and the extension pipe 11, reducing the occurrence of cracking of the main body 1 of the pipe fitting along the dashed line K.

[0030] Example 2:

[0031] like Figures 3-6As shown, the extension pipe 11 is provided with a groove 112, which is located at the end of the extension pipe 11 away from the main body 1. The groove 112 is I-shaped, and the axial direction of the I-shape is radially arranged along the extension pipe 11. The groove 112 radially penetrates the inner wall of one side of the extension pipe 11. A filler block 2 is installed in the groove 112. The filler block 2 is inserted into the groove 112 with an interference fit. The filler block 2 is made of rubber and is shaped like an I-shape that aligns with the groove 112 to prevent the filler block 2 from detaching from the groove 112 during use.

[0032] like Figure 6 As shown, the channel 111 is inserted into the pipe 3. Since the pipe 3 is connected to other fixed components, when the pipe 3 is slightly tilted, the inner ring of the channel 111 on the side away from the main body 1 is most severely squeezed by the pipe 3 and is most prone to cracking. By setting the groove 112, the deformation resistance of the inner ring of the channel 111 on the side away from the main body 1 is increased. When the inner ring is subjected to the spreading force, it can deform without cracking, thus improving the load-bearing capacity.
