[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] See attached document Figure 1 , 2 3. A ball valve function testing mechanism for train interiors, comprising an air circuit sealing mounting plate 1, a clamping mechanism 2, an air nozzle 3, an air pipe 4, and an air pipe 5. The air circuit sealing mounting plate 1 has ventilation holes that cooperate with the air nozzle 3, the air pipe 4, and the air pipe 5. The air nozzle 3, the air pipe 4, and the air pipe 5 cooperate with the ball valve 12. The clamping mechanism 2 comprises a cylinder bracket 6, a cylinder 7, a pull rod 8, a pull plate 9, a gripper 10, and a gripper seat 11. The cylinder barrel of the cylinder 7 is fixed on the cylinder bracket 6, and the cylinder bracket 6 is fixed on the air circuit sealing mounting plate 1. The cylinder rod of the cylinder 7 is drivenly connected to the pull plate 9. Both ends of the pull plate 9 are connected to a pull rod 8. The two pull rods 8 pass through the air circuit sealing mounting plate 1 and are connected to a gripper 10. The two grippers 10 cooperate with the ball valve 12.

[0016] In this embodiment, refer to the appendix. Figure 1 , 2 3. The testing mechanism includes an air circuit sealing mounting plate 1, a clamping mechanism 2, an air nozzle 3, an air pipe 4, and an air pipe 5. The clamping mechanism 2 includes a cylinder bracket 6, a cylinder 7, a pull rod 8, a pull plate 9, a gripper 10, a gripper seat 11, a ball valve 12, and a ball valve positioning seat 13. The ball valve 12 is fixed to the air circuit sealing mounting plate 1 by the ball valve positioning seat 13. The air circuit sealing mounting plate 1 has a vent hole for installing the air nozzle 3, air pipe 4, and air pipe 5, which facilitates quick connection with the ball valve 12. Air pipe 4 and air pipe 5 are inflated respectively. The pressure sensor values ​​connected to air pipe 4 and air pipe 5 can be used to verify the functionality of the overhauled ball valve 12 to ensure successful installation.

[0017] The cylinder bracket 6 is used to fix the cylinder 7 on the air circuit sealing mounting plate 1. Two tie rods 8 are symmetrically arranged on both sides of the cylinder 7. One end of each tie rod is rotatably connected to the pull plate 9 through a pin, and the other end is rotatably connected to the gripper 10 through a pin. The gripper 10 is an arc shape that cooperates with the ball valve 12.

[0018] When testing the function of the ball valve inside the train, first close the handle of ball valve 12 and inflate air pipe 4. If there is no pressure change at the pressure sensor connected to air pipe 5 within 120 seconds, then open the handle of ball valve 12 and continue to inflate air pipe 4 until the pressure at the pressure sensor connected to air pipe 5 is the same as the air source. Then close the handle of ball valve 12. If there is no change at the pressure sensor connected to air pipe 5 within 120 seconds, it proves that ball valve 12 is functioning normally.
