[0027] Below will continue to elaborate based on the above embodiment for some preferred / improved embodiment, the following embodiment can be selected, or selected to combine multiple.

[0028] As Figure 1 shown, the electric push rod 2 is installed on both sides of the workbench 1, and the output end of the electric push rod 2 is connected to the support plate 4, and the bottom of the support plate 4 is slidably connected to the slide rail 3. The electric push rod 2 is used to push the support plate 4 to translate in the slide rail 3 to a position suitable for the length of the valve 15, so as to adapt to the valve 15 of different length specifications.

[0029] As Figure 3 shown, the support plate 4 has a circular through hole 401, a through hole 402 is opened on one side of the circular through hole 401, and the capstan 9 is installed in the through hole 402. The position of the capstan 9 is in the same plane as the elastic ring 7, which is used to connect with the tightening rope 6. The motor 8 drives the capstan 9 to rotate, winds the tightening rope 6, and then realizes the function of tightening the elastic ring 7 to seal the valve 15.

[0030] Further, a platform 403 is arranged on the left side of the through hole 402, and the motor 8 is installed on the platform 403. The output end of the motor 8 penetrates the support plate 4 and is connected with the shaft of the capstan 9. The motor 8 improves the tightening efficiency and ensures the sealing performance.

[0031] Specifically, one side of the elastic ring 7 is an elastic ring 701, and the other side is a funnel-shaped elastic sleeve 702. The elastic ring 701 and the elastic sleeve 702 are both elastic and plastic, and have a strength that can withstand a certain water pressure. The elastic ring 7 is fixed with the inner wall of the circular through hole 401 through a plurality of pull ropes 5. When the elastic ring 7 is tightened, the pull ropes 5 are simultaneously elongated.

[0032] As Figure 5As shown, the elastic ring 701 is internally provided with an annular groove 17, and the tightening rope 6 is sleeved in the annular groove 17. The tightening rope 6 is crossed and then respectively passes through the elastic ring 701. One end of the tightening rope 6 is fixed on the support plate 4, and the other end is wound on the winch 9. The winch 9 is rotated to tighten or loosen the tightening rope 6, so as to realize the functions of tightening and releasing the valve 15.

[0033] In some embodiments, one side of the workbench 1 is provided with a water tank 18, and one side of the elastic sleeve 702 is provided with a water outlet pipe 19 connected with the water tank 18. An electromagnetic valve 21 is mounted on the water outlet pipe 19 to control the water flow in the water outlet pipe 19. One end of the water pump 16 is connected with the water tank 18 through a water pipe to supply water, and the water pump 16 can also be externally connected with other water sources.

[0034] As shown in the figure, Figure 6 The positioning tool is fixed in the middle section of the slide rail 3 through a fixing block 21 mounted on the bottom of the positioning tool. The fixing block 21 is rotatably connected with the threaded sleeve 10. The threaded sleeve 10 is internally threadedly connected with a screw rod 11. The upper end of the screw rod 11 is fixedly provided with the concave bracket 12. The screw rod 11 and the concave bracket 12 are lifted and lowered by rotating the threaded sleeve 10.

[0035] Further, the concave bracket 12 is provided with a bidirectional screw rod 13 penetrating through the concave bracket 12. One end of the bidirectional screw rod 13 is provided with a rocker 22. The V-shaped clamping blocks 14, the sealing mechanism and the electric push rods 2 are arranged in pairs. The V-shaped clamping blocks 14 at both ends of the bidirectional screw rod 13 are driven to move towards each other by rotating the bidirectional screw rod 13 through the rocker 22, so as to clamp and fix the valve 15 of different specifications.

[0036] Specifically, after the valve 15 is clamped and fixed by the positioning tool, the support plates 4 are driven by the electric push rods 2 to move towards each other in the slide rail 3. When the port of the valve 15 enters the elastic ring 7, the winch 9 is driven to rotate by the click operation arranged on the platform 403, so as to tighten the tightening rope 6. The elastic ring 7 is tightened until the diameter of the elastic ring 7 is completely in contact with the valve 15 to seal the valve 15. The above steps are simultaneously performed on both ends of the valve 15. Then, the electromagnetic valve 21 on the water outlet pipe 19 is closed, the water pump 16 is started, and water is pumped from the water tank 18 or other externally connected water sources. The water is injected into the valve 15 through the water inlet pipe 20. Whether the valve 15 is sealed is determined by observing whether there is water leakage. Finally, the electromagnetic valve 21 is opened to return part of the water to the water tank 18, so as to realize the recycling of water.
