[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figures 1-4 The utility model provides a technical solution: an exhaust gas bypass valve on a vehicle turbocharger, comprising a bypass valve body 1, with connecting pipes 3 provided at both ends of the bypass valve body 1, one end of the connecting pipe 3 being located on the outside of the bypass valve body 1 and having a connecting port 2, one end of the connecting pipe 3 extending to the inside of the connecting port 2, and a sealing strip being provided on the inner wall of the connecting port 2 on the outside of the connecting pipe 3, thereby facilitating the connection between the bypass valve body 1 and the connecting pipe 3;

[0023] See also Figure 2-Figure 4In this embodiment, the four ends of the connecting tube 3 are located on the outer end surface of the connecting port 2 and are provided with displacement grooves 12. The inner side of the displacement groove 12 is movably connected with a displacement block 5. A knob 4 is provided on one side of one of the displacement blocks 5. The bottom end of the knob 4 extends through and extends to the inner side of the connecting port 2. One side of the bottom end of the knob 4 is located on the inner wall of the connecting port 2 and is provided with a transmission disc 9. The bottom end of the knob 4 is located on the outer side of the transmission disc 9 and is provided with a gear. The knob 4 is meshed with the transmission disc 9 through the gear. A through hole is provided at the center of the transmission disc 9. The number of displacement blocks 5 and the transmission gear 10 is the same, and one side of the top end of the transmission gear 10 is located at the bottom end of the displacement block 5. A rack 11 is provided, and a transmission gear 10 is provided on the outside of the transmission disc 9. The top of the transmission gear 10 extends to one side of the displacement block 5. Gears are provided at the upper and lower ends of the transmission gear 10. The transmission gear 10 is respectively engaged with the displacement block 5 and the transmission disc 9 through gears. When the bypass valve body 1 is connected to the connecting pipe 3, the knob 4 is rotated, and the knob 4 drives the transmission gear 10 to rotate through the transmission disc 9. Since the transmission gear 10 is respectively engaged with the displacement block 5 and the transmission disc 9 through gears, the transmission disc 9 drives the displacement block 5 to slide and displace on the inner side of the connecting port 2 through the transmission gear 10;

[0024] See also Figure 2-Figure 3 In this embodiment, a clamping block 6 is provided at the bottom end of the displacement block 5, and a limit block 8 is provided at the bottom end of the clamping block 6. A limit groove 7 is provided below the limit block 8 on the outside of the connecting pipe 3. The displacement block 5 and the clamping block 6 are an integrated structure. The limit block 8 and the limit groove 7 have the same shape and size. The limit block 8 is clamped on the inner side of the limit groove 7, and then during the sliding displacement process of the displacement block 5, the displacement block 5 clamps the connecting pipe 3 through the clamping block 6, and a limit block 8 is provided at the bottom end of the clamping block 6. A limit groove 7 is provided below the limit block 8 on the outside of the connecting pipe 3. The limit block 8 and the limit groove 7 have the same shape and size, and then the stability of the connection between the bypass valve body 1 and the connecting pipe 3 is improved by the limit block 8.

[0025] When working, the connecting pipe 3 is inserted into the inner side of the bypass valve body 1, and then the knob 4 is rotated. The knob 4 drives the transmission gear 10 to rotate through the transmission disc 9. Since the transmission gear 10 is engaged with the displacement block 5 and the transmission disc 9 through gears, the transmission disc 9 drives the displacement block 5 to slide and displace on the inner side of the connecting port 2 through the transmission gear 10. During the sliding displacement process of the displacement block 5, the displacement block 5 clamps the connecting pipe 3 through the clamping block 6, and a limit block 8 is provided at the bottom end of the clamping block 6. A limit groove 7 is provided on the outside of the connecting pipe 3 below the limit block 8. The limit block 8 and the limit groove 7 have the same shape and size, thereby improving the stability of the connection between the bypass valve body 1 and the connecting pipe 3 through the limit block 8.

[0026] Through the above steps, by rotating the knob 4, the knob 4 clamps the displacement block 5 and the clamping block 6 to the connecting pipe 3 through the transmission disc 9 and the transmission gear 10, and the bottom end of the clamping block 6 is provided with a limit block 8, and the limit block 8 and the limit groove 7 on the outside of the connecting pipe 3 have the same shape and size. The limit block 8 is inserted into the inner side of the limit groove 7, and then the stability of the connection between the bypass valve body 1 and the connecting pipe 3 is improved by the limit block 8, which solves the problem that most of the existing bypass valves and pipelines are connected by flanges and multiple bolts. This connection method is relatively complicated and cumbersome, making disassembly and assembly inconvenient and affecting the disassembly and assembly efficiency.
