The connecting assembly 2 includes a connecting disc 21, an annular plate 22, a limiting plate 23, a limiting hole 24, a connecting pipe 25, a fixed disc 26, a clearance groove 27, a limiting assembly 28 and a flange 29. The connecting disc 21 is fixedly installed on the bottom surface of the EGR valve body 1. The bottom surface of the connecting disc 21 is fixedly installed with an annular plate 22. A fixing disc 26 is provided inside the annular plate 22. The thickness of the fixing disc 26 is the same as that of the annular plate 22. The bottom surface of the disk 26 is fixedly installed with a connecting pipe 25, and two symmetrically distributed limiting plates 23 are fixedly installed on one side of the annular plate 22 close to the fixed disk 26. The two limiting plates 23 are provided with a limiting hole 24 on one side facing the middle of the fixed disk 26. The arc surface of the fixed disk 26 is provided with two symmetrically distributed making way grooves 27. The contour of the making way grooves 27 matches the limiting plates 23. Two limiting components 28 are provided on the side wall of the connecting pipe 25 relative to the limiting holes 24. The limiting component 28 includes a sleeve 281, a limiting column 282, and a spring. The spring 283, the limiting ring 284, the moving ring 285 and the U-shaped rod 286, the sleeve 281 is fixedly mounted on the side wall of the connecting pipe 25, the internal movable sleeve of the sleeve 281 is fitted with the limiting column 282, the diameter of the limiting column 282 is the same as the diameter of the limiting hole 24, the bottom surface of the inner part of the sleeve 281 is fixedly welded with one end of the spring 283, and the other end of the spring 283 is fixedly welded to the bottom surface of the limiting column 282. By aligning the limiting plate 23 with the clearance groove 27 and passing through the clearance groove 27, and then moving the limiting plate 23 closer to the clearance groove 27, the limiting plate 23 is moved closer to the clearance groove 27. 8 is rotated on one side, and then the limiting post 282 is squeezed to move toward the inside of the sleeve 281. When the limiting hole 24 is aligned with the top of the limiting post 282, the limiting post 282 will move to the inside of the limiting hole 24 under the action of the elastic force of the spring 283. Then, the limiting post 282 can limit the limiting plate 23, preventing the limiting hole 24 from rotating freely along the side wall of the fixing plate 26, thereby achieving the purpose of stably connecting the connecting plate 21 and the fixing plate 26, which is conducive to improving the stability of the EGR valve body 1 after installation;

[0022] Example 2: Figure 2-4 As shown: the top end of the outer surface of the sleeve 281 is fixedly sleeved with a limit ring 284, and the outer surface of the sleeve 281 is movably sleeved with a movable ring 285. The arc surface of the movable ring 285 is fixedly installed with one end of a U-shaped rod 286, and the other end of the U-shaped rod 286 is fixedly installed on the side wall of the limit column 282. The bottom surface of the connecting pipe 25 is fixedly installed with a flange 29.

The U-shaped rod 286 is used to easily drive the limit column 282 to squeeze the spring 283, and the flange 29 can be stably installed in the installation area using bolts.

[0023] The working principle and usage process of the present invention are as follows: When using the EGR valve which is easy to install, the flange 29 can be stably installed in the installation area using bolts, and then the position of the EGR valve body 1 can be moved with one hand, the limit plate 23 is aligned with the give way groove 27 and passed through the give way groove 27, and then the limit plate 23 is rotated to the side close to 8, and then the U-shaped rod 286 is driven by the other hand to move to the side close to the spring 283, so that the spring 283 is compressed, and then the limit post 282 moves toward the inside of the sleeve 281. When the limit hole 24 is aligned with the top end of the limit post 282, the U-shaped rod 286 is released, and then the limit post 282 will move to the inside of the limit hole 24 under the action of the elastic force of the spring 283, and then the limit post 282 can limit the limit plate 23, preventing the limit hole 24 from rotating freely along the side wall of the fixed plate 26, and the installation of the EGR valve body 1 can be completed.
