At present, all protective sealed doors are produced and processed according to the requirements of the design drawings. Due to the large number of manufacturers, diverse and complex equipment types, there are relatively few detection means and detection equipment in the production process. Without effective quality supervision, the product quality and service performance are difficult to be effectively guaranteed, resulting in greater potential hazards when the sealed valves are in use.

[0003] The patent with the publication number of CN 207197735 U discloses a valve air tightness detection device, which includes a detection box body, a lifting assembly and a test platform. The detection box body is suspended by columns at four ends, and cross beams are connected to the tops of adjacent columns on the same side. The lifting assembly is erected on the cross beam and connected to the test platform arranged in the detection box body. The utility model can efficiently test the air tightness of the valve, reduce the steps of manual operation, improve the automation performance of the detection, and moreover, the detection device can control the pressure value and pressurization time of the valve detection, and can detect the air tightness of various different types of valves.

[0004] In the process of implementing the present utility model, the inventor found that there are at least the following problems in this technology. Since a large amount of water droplets and water stains will adhere to the surface of the valve after detection, the lack of a drying structure will lead to the residue of this part of the water stains, resulting in rust and other situations, thus affecting the use. And the device detects multiple groups of valves at the same time. Therefore, the installation, disassembly and drying of the valves will take a lot of time, thus affecting the progress of the detection work. Content of the Utility Model

[0025] Specifically, as Figure 1 and Figure 2 shown, a connecting rod 10 is fixedly connected in the inner cavity of the working frame 2. The moving block 7 is sleeved on the outer ring of the connecting rod 10 and can move back and forth in the front and back directions of the outer ring of the connecting rod 10. The connecting rod 10 restricts the moving direction of the moving block 7.

[0026] When in specific use, for a valve airtightness detection device of the present utility model, after the valve detection is completed, at this time, the electric push rod 16 contracts, driving the lifting plate 17 and the clear water to move downward until the clear water is away from the valve. At this time, the dryer 9 is started, and the dryer 9 blows hot air to the surface of the valve to achieve the drying effect. When the valve at one position is dried, at this time, the servo motor 4 is started, driving the rotation of the lead screw 6, and then driving the moving block 7 connected by threads to move in the inner cavity of the limiting hole 3. During the movement of the moving block 7, it drives the moving plate 8 and the dryer 9 to move, drying the valve at the next position. At the same time, the dried valve is removed, and a new valve to be detected is replaced, thus not only achieving the purpose of drying to prevent rust, but also achieving the effect of drying and installing and disassembling the valve simultaneously, saving time and improving the detection efficiency.

[0027] Embodiment 2:

[0028] On the basis of Embodiment 1, as Figure 3 and Figure 4 shown, a support plate 11 is fixedly connected to the back surface of the box body 1. The top of the support plate 11 is fixedly connected with a flat plate 12. The top of the flat plate 12 is fixedly connected with a water tank 13. The top of the water tank 13 is fixedly connected with a water pump 14. The bottom of the water tank 13 is fixedly connected with a water pipe 15. Both sides of the lifting plate 17 are fixedly connected with sliders 19. A sliding groove 18 is opened on the inner wall of the box body 1. The sliders 19 are arranged in the inner cavity of the sliding groove 18. The sliders 19 and the sliding groove 18 restrict the moving direction of the lifting plate 17. A fixing plate 20 is fixedly connected to the inner wall of the box body 1. A through hole 21 is opened in the inner cavity of the fixing plate 20. A limiting clip 22 is fixedly connected in the inner cavity of the through hole 21. The through holes 21 and the limiting clips 22 are distributed in a multi-group linear array.

[0029] During specific use, for a valve airtightness detection device of the present utility model, the water pump 14 is started. The water pump 14 pumps the clear water required for detection into the inner cavity of the box body 1 through the water pipe 15. Due to the limitation of the lifting plate 17, the clear water stays at the top of the lifting plate 17. The valve to be detected is placed in the inner cavity of the through hole 21 and fixed by the limit clamp 22. Subsequently, the electric push rod 16 is started, causing the electric push rod 16 to extend and drive the lifting plate 17 to move upward. Sliders 19 are arranged on both sides of the lifting plate 17, and the sliders 19 can slide in the inner cavity of the sliding groove 18. Therefore, the cooperation between the sliding groove 18 and the sliders 19 can limit the moving direction of the lifting plate 17 up and down, making the movement of the lifting plate 17 more stable. During the upward movement of the lifting plate 17, the clear water at the top of the lifting plate 17 will be squeezed upward, thereby providing water pressures of different magnitudes to facilitate the detection of the valve. For the specific working principle of the detection, reference can be made to the patent with the publication number CN 207197735 U, which belongs to the category of the prior art and will not be elaborated here. Sealing gaskets are provided in the areas where the lifting plate 17 contacts the inner wall of the box body 1, so that during the movement of the lifting plate 17, the clear water will not leak out from the gap between the lifting plate 17 and the box body 1.

[0030] Working principle: Start the electric push rod 16, causing the electric push rod 16 to extend and drive the lifting plate 17 to move upward, squeezing the clear water at the top of the lifting plate 17 upward, thereby providing water pressures of different magnitudes to facilitate the detection of the valve. When the valve detection is completed, at this time, the electric push rod 16 contracts, driving the lifting plate 17 and the clear water to move downward until the clear water is away from the valve. At this time, start the dryer 9, and the dryer 9 will blow hot air onto the surface of the valve to achieve the drying effect. When the valve at one position is dried, at this time, start the servo motor 4, drive the rotation of the lead screw 6, and then drive the moving block 7 connected by threads to move in the inner cavity of the limit hole 3. During the movement of the moving block 7, it will drive the moving plate 8 and the dryer 9 to move, dry the valve at the next position, and at the same time remove the dried valve and replace it with a new valve to be detected, thus not only achieving the purpose of drying to prevent rust, but also achieving the effect of drying and installing and disassembling the valve simultaneously, saving time and improving the detection efficiency.
