Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0025] In the present application, as Figures 1 to 2As shown, the provided expansion tank with a bent pipe comprises a tank body 1, a supporting leg 2 arranged at the bottom of the tank body 1, and a through hole arranged at the bottom of the tank body 1, wherein the expansion tank further comprises a bent pipe 3 installed in the through hole, the bent pipe 3 comprises a vertical segment 301 connected to the tank body 1, an arc segment 302 connected to the bottom of the vertical segment 301, and a connecting segment 303 connected to one end of the arc segment 302 away from the vertical segment 301, and the vertical segment 301, the arc segment 302 and the connecting segment 303 are integrally arranged, the bent pipe 3 further comprises a positioning rib 4 installed on the inner side of the arc segment 302, and the lower end of the positioning rib 4 is connected to the connecting segment 303 and the upper end of the positioning rib 4 is connected to the tank body 1.

[0026] In the processing of the expansion tank, one working condition is that the supporting leg 2 is fixedly installed at the bottom of the tank body 1, and when the connecting segment 303 of the bent pipe 3 needs to be positioned towards the relative position of the supporting leg 2 during the installation of the bent pipe 3 (for example, the supporting leg 2 has a special communication hole in the embodiment shown in the figure), the positioning rib 4 can be used to install and position the water outlet end of the bent pipe 3 (for example, as shown in one example, the special tool positioning can be used, for example, one end of the special tool is positioned and inserted into the communication hole, and the other end is provided with a positioning block having a positioning groove, and the positioning rib 4 is positioned and inserted into the positioning groove), so as to prevent the supporting leg 2 from interfering with the installation during the on-site pipeline installation. Figure 2 In another working condition, the supporting leg 2 is installed after the installation of the bent pipe 3, and when the connecting segment 303 of the bent pipe 3 needs to be positioned towards the relative position of the supporting leg 2 during the installation of the supporting leg 2 (for example, the supporting leg 2 has a special communication hole in the embodiment shown in the figure), the positioning rib 4 can be used to install and position the supporting leg 2 (for example, as shown in one example, the special tool positioning can be used, for example, one end of the special tool is positioned and inserted into the communication hole, and the other end is provided with a positioning block having a positioning groove, and the positioning rib 4 is positioned and inserted into the positioning groove), so as to prevent the supporting leg 2 from interfering with the installation during the on-site pipeline installation. Figure 2
