[0002] Valves are key control components in fluid transport systems, used to regulate, guide, and control parameters such as fluid flow direction, flow rate, pressure, and temperature. They play an indispensable role in many fields, including industry, civil use, and municipal applications. Traditional valve sealing testing methods mostly rely on the bubble method, which requires immersing the valve in water and then filling it with air to observe whether bubbles are generated to determine the sealing condition. However, existing valve sealing testing methods require a significant amount of manpower and time for valve installation, resulting in low efficiency in valve testing and positioning. Summary of the Invention

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 7 This utility model provides a technical solution: a valve sealing detection device, comprising: a support frame 1, a fixed support box 2, an outer sliding frame 3, a support slide plate 4, a support plate 5, a first connecting pipe 8, a three-jaw chuck 15, a clamping plate 16, and a side fixed box 21; the fixed support box 2 is bolted to the inside of the support frame 1; the outer sliding frame 3 is symmetrically slidably arranged on the outside of the fixed support box 2; the support plate 5 is fixed to the bottom of the outer sliding frame 3; the three-jaw chuck 15 is installed inside the support plate 5; the clamping plate 16 is equidistantly installed on the three-jaw chuck. On the jaws of the 15, an inner jacking plate 17 is fixedly connected to the inner side of the clamping plate 16; a first connecting pipe 8 is slidably installed on the inner side of the three-jaw chuck 15, a pressure sensor 10 is installed on the first connecting pipe 8, and a nozzle 18 is installed at one end of the first connecting pipe 8; a side fixing box 21 is installed on one side of the support plate 5 by bolts, and the side fixing box 21 is slidably connected to the fixed support box 2; a support slide plate 4 is slidably set inside the side fixing box 21, the first connecting pipe 8 is fixedly connected inside the support slide plate 4, and a solenoid valve 11 is installed on the first connecting pipe 8.

[0030] It should be noted that in this embodiment, the valve to be tested is kept closed and placed inside the three-jaw chuck 15. The servo motor 23 drives the bidirectional lead screw 12 to rotate. When the bidirectional lead screw 12 rotates, it drives the symmetrically moving sliders 13 on the outer side to move. The moving sliders 13 drive the outer sliding frame 3, support plate 5, and sliding base 7 to move synchronously. The sliding base 7 slides on the guide slide 6. The valve is tightened and fixed by the inner push plate 17 inside the clamping plate 16. The three-jaw chuck 15 includes a transmission gear set: a large bevel gear located at the center of the chuck, on the back side. The chuck features a machined flat thread; three small bevel gears evenly distributed around the large bevel gear, meshing with it. When any small bevel gear is driven by the wrench, the large bevel gear rotates accordingly; a chuck assembly consisting of three chucks evenly distributed on the flat thread of the large bevel gear, with threaded structures at the bottom of the chucks matching the flat thread; a guide groove on the chuck body to restrict the chucks to move only in a radial straight line, preventing deflection; a drive component: a wrench inserted into the square hole of the small bevel gear, applying torque through rotation; and a power source, which, depending on the chuck type, can be a manual wrench, a hydraulic cylinder, or an electric wrench. The machine, through the jaws, moves the clamping plate 16 and the inner push plate 17, clamping and fixing the valve through the clamping plate 16. Water is injected through an external water supply device connected to the water inlet pipe 9. Water is injected through one of the water inlet pipes 9, one solenoid valve 11 is opened, and the other solenoid valve 11 is closed. Test water enters the first connecting pipe 8 and the installation nozzle 18 through one of the water inlet pipes 9. Test water is injected into the valve through the installation nozzle 18 to observe the valve's sealing status. The sealing status of the valve is observed through leakage. The other solenoid valve 11 remains closed, and pressure is applied to the valve. Force sensor 10 detects the air pressure in another No. 1 connecting pipe 8 and tests the sealing effect on one side of the valve to be tested. In the valve testing chamber without distinguishing between the inlet and outlet ends, the water in one of the No. 1 connecting pipes 8 is released, the valve to be tested is re-clamped, and water is injected through another inlet pipe 9, the No. 1 connecting pipe 8, and the installed nozzle 18. The air pressure is detected by one of the pressure sensors 10. After the test on one side is completed, the valve to be tested is opened to test the water flow pressure resistance of the valve and observe whether there is any leakage.

[0031] In one embodiment, such as Figure 5 As shown, a second limiting rod 20 is symmetrically slidably arranged inside the supporting slide plate 4. The second limiting rod 20 is fixedly connected to the side fixing box 21. A cylinder 19 is installed inside the side fixing box 21 by bolts. The output end of the cylinder 19 is fixedly connected to the supporting slide plate 4.

[0032] It should be noted that in this embodiment, the output end of the cylinder 19 drives the support slide plate 4 to slide within the side fixed box 21. The support slide plate 4 drives the first connecting pipe 8, the installation nozzle 18, and the valve sealing sleeve 22 to move, installing the installation nozzle 18 and the valve sealing sleeve 22 suitable for the valve being tested. The valve sealing sleeve 22 cooperates with the valve, and the installation nozzle 18 and the valve sealing sleeve 22 enter the valve to perform sealing test processing.

[0033] In one embodiment, such as Figure 2 , Figure 4 and Figure 7 As shown, a bidirectional lead screw 12 is rotatably installed inside the fixed support box 2. A movable slider 13 is symmetrically installed on the outside of the bidirectional lead screw 12. The movable slider 13 is slidably connected to the fixed support box 2. The bottom of the movable slider 13 is fixedly connected to the support plate 5. A first limit rod 14 is symmetrically slidably installed inside the movable slider 13. The first limit rod 14 is fixedly connected to the fixed support box 2. A servo motor 23 is installed inside the fixed support box 2. The output end of the servo motor 23 is fixedly connected to the bidirectional lead screw 12.

[0034] It should be noted that, in this embodiment, when the bidirectional lead screw 12 rotates, it drives the outer symmetrical movable slider 13 to move. The movable slider 13 drives the outer sliding frame 3, the support plate 5 and the three-jaw chuck 15 to move, thereby completing the positioning process of the valve.

[0035] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, a guide slide 6 is fixedly connected inside the support frame 1, and a sliding base 7 is fixedly connected to the bottom of the support plate 5.

[0036] It should be noted that in this embodiment, the sliding base 7 is limited and supported by the guide slide 6, and the sliding base 7 slides at the upper limit of the guide slide 6, thereby improving the stability of the support plate 5 and the outer sliding frame 3.

[0037] In one embodiment, such as Figures 1 to 7 As shown, one end of the first connecting pipe 8 is fixedly connected to the water inlet pipe 9.

[0038] It should be noted that in this embodiment, water is injected into the No. 1 connecting pipe 8 through the water inlet pipe 9, and the water in the No. 1 connecting pipe 8 is sprayed out through the installed nozzle 18 to perform a sealing test on the valve.

[0039] In one embodiment, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a valve sealing sleeve 22 is provided on the outside of the nozzle 18.

[0040] It should be noted that in this embodiment, the valve connection is sealed by the valve sealing sleeve 22.
