However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example

[0025] Please see Figure 1-6 As shown, this invention provides a mobile docking valve technical solution: it includes a rear pipe 11 and a front pipe 12. Specifically, the rear pipe 11 is connected to a dust removal main pipe, a material conveying main pipe, or a material storage tank. The front pipe 12 is a discharge pipe. A drive seat 2 is provided on the rear pipe 11. Specifically, the drive seat 2 is connected to the end face of the rear pipe 11. A docking inner sleeve 13 is provided at the end of the drive seat 2. Specifically, the drive seat 2, the docking inner sleeve 13, and the rear pipe 11 are fixedly connected. A synchronization mechanism is provided on the rear pipe 11. The synchronization mechanism includes an electro-hydraulic actuator 31. A push rod 32 is provided at the output end of the electro-hydraulic actuator 31. A connector 34 is provided on the end face of the push rod 32. Specifically, the connector 34 is U-shaped. A connecting rod 35 is provided below the connector 34. A docking outer sleeve 5 is provided at the bottom of the connecting rod 35. Specifically, the connecting rod 35 is fixedly connected to the docking sleeve 5, which is fitted over the docking inner sleeve 13. The drive seat 2 is equipped with a valve assembly, which includes a valve seat 21 located inside the drive seat 2. A valve stem 23 is mounted on the valve seat 21. Specifically, the valve stem 23 is rotatably engaged with the valve seat 21. The valve stem 23 passes through the valve seat 21 and extends downward. The top of the valve stem 23 is equipped with a housing 22, which passes through the housing and is connected to it. The valve stem 23 is rotatably connected to the housing 22. A gear 24 is mounted on the valve stem 23 located inside the housing 22. A push rod 32 passes through the housing 22 and is slidably engaged with the housing 22. A rack 33 is mounted on the push rod 32, which meshes with the gear 24. A valve plate 25 is mounted at the bottom of the valve stem 23.

[0026] In this embodiment, during the moving docking, the electro-hydraulic actuator 31 is activated. When the electro-hydraulic actuator 31 drives the actuator 32 to operate, the actuator 32 drives the docking sleeve 5 to move through the connecting rod 35 until the docking sleeve 5 is docked with the front pipe 12. At the same time as docking, the rack 33 on the actuator 32 meshes with the gear 24 of the valve stem 23. When the gear 24 and the valve stem 23 rotate, the valve plate 25 can be driven to rotate, and the valve plate 25 opens and closes, realizing the synchronous operation of valve moving docking and valve opening and closing.

[0027] Please see Figure 1-6 As shown, furthermore, the inner sleeve 13 and the front pipe 12 are provided with sealing components. The sealing components include a first docking seat 41 and a second docking seat 43. The first docking seat 41 is connected to the outer wall of the inner sleeve 13 and is provided with a first sealing gasket 42. The inner wall of the outer sleeve 5 is provided with an inner ring 51, which cooperates with the first docking seat 41. The second docking seat 43 is connected to the edge of the front pipe 12 and is provided with a second sealing gasket 44. The outer sleeve 5 cooperates with the second docking seat 43.

[0028] In this embodiment, the end face of the outer sleeve 5 abuts against the second-stage docking seat 43, and the second sealing gasket 44 achieves a seal between the outer sleeve 5 and the interface of the outer sleeve 5. The inner ring 51 on the inner wall of the outer sleeve 5 abuts against the first docking seat 41, and the first sealing gasket 42 achieves a seal between the outer sleeve 5 and the interface of the outer sleeve 5.

[0029] Please see Figure 1-6 As shown, a sliding positioning assembly is further provided between the drive seat 2 and the docking sleeve 5. The sliding positioning assembly includes a track seat 61 distributed in a relatively opposite manner. A bracket 62 is provided above and below the track seat 61. The bracket 62 is connected to the docking sleeve 5. A positioning roller 63 is provided below the bracket 62. The positioning roller 63 slides and engages with the track seat 61.

[0030] In this embodiment, when the push rod 32 drives the docking jacket 5 to move, the positioning roller 63 rolls along the track seat 61 to ensure the stable movement of the docking jacket 5.

[0031] Specifically, the working principle and usage process of this invention are as follows: During the moving docking, the electro-hydraulic actuator 31 is activated. When the electro-hydraulic actuator 31 drives the actuator 32 to operate, the actuator 32 drives the docking sleeve 5 to move through the connecting rod 35 until the docking sleeve 5 is docked with the front pipe 12. At the same time as docking, the rack 33 on the actuator 32 meshes with the gear 24 of the valve stem 23. When the gear 24 and the valve stem 23 rotate, the valve plate 25 can be driven to rotate. The valve plate 25 opens and closes, realizing the synchronous operation of valve moving docking and valve opening and closing until the entire working sequence is completed.
