Abstract
Description
Technical Field
[0001] The present invention relates to an internal heating detection device, and particularly to an internal heating detection device for high-temperature valves, belonging to the technical field of valve detection equipment. Background Art
[0002] In a fluid delivery system, a valve is an essential control component, mainly having functions such as regulation, diversion, anti-backflow, cut-off, and flow splitting. Valves are widely used in industrial and civil fields. High-temperature valves are a relatively common type of valve. During the production of high-temperature valves, it is necessary to conduct high-temperature detection on the sealing packing inside the valve to prevent problems such as the melting of the packing during the transportation of high-temperature fluids, resulting in a decline in sealing performance. In the prior art, most traditional high-temperature detections of valves directly heat the outside of the valve, making it impossible to effectively simulate the damage of high-temperature fluids to the sealing packing during the detection process. Therefore, an internal heating detection device is proposed to detect from the inside of the valve to improve the accuracy of temperature simulation. Summary of the Invention
[0003] The purpose of the present invention is to provide an internal heating detection device for high-temperature valves. By arranging a heating plate that can rotate relatively inside the valve for heating, heating is carried out from the inside of the valve to test the heat resistance of the valve sealing packing. The door of this heating box can be pulled out of the heating box by the sliding of the first slide bar, which is convenient for opening the box body. The clamping mechanism of the valve can be conveniently removed after sliding out of the heating box by the sliding of the second slide bar.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0018] Please refer to Figures 1-4, the internal thermal detection device for high-temperature valves of the present invention includes a heating box 1. On both sides of the top of the inner wall of the heating box 1, two groups of first slideways 2 are fixedly connected relatively. A first slide rod 3 is slidably connected inside the first slideway 2. One end of the first slide rod 3 outside the heating box 1 is fixedly connected with a box door 4. The box door 4 is closed with the heating box 1. At one end of the heating box 1 away from the box door 4, a rotating block 10 is rotatably connected. On both sides of the rotating block 10, two second slideways 11 are fixedly connected relatively. A second slide rod 12 is slidably connected to both adjacent sides of the second slideway 11. On one side of the two second slide rods 12 close to each other, a clamp 15 is provided.
[0019] In the middle of the side of the box door 4 close to the heating box 1, a connecting plate 5 is fixedly connected. The connecting plate 5 is fixedly connected with a heating plate 51. Outside one end of the heating box 1 away from the box door 4, a second belt pulley 8 is provided. The second belt pulley 8 passes through the heating box 1 and is fixedly connected with the rotating block 10. At the top of one end of the heating box 1 away from the box door 4, a motor 6 is fixedly connected. The output end of the motor 6 is fixedly connected with a first belt pulley 7. The first belt pulley 7 is connected with the second belt pulley 8 through a transmission belt 9. The rotation of the rotating block 10 drives the valve to rotate inside the heating box 1 through the transmission of the first belt pulley 7 and the second belt pulley 8. At the top of one end of the second slideway 11 close to the box door 4, a positioning bolt 13 is threadedly connected. The positioning bolt 13 contacts the second slide rod 12. On one side of the second slide rod 12 close to the clamp 15, a threaded sleeve 14 is rotatably connected. The threaded sleeve 14 is threadedly connected with a threaded rod 16. The threaded rod 16 is fixedly connected with the clamp 15. As the threaded sleeve 14 rotates, the threaded rod 16 moves away from the threaded sleeve 14, and the two clamps 15 approach each other to clamp and fix the valve.
[0020] Specifically, when the present invention is used, pull the box door 4 to pull the box door 4 out of the heating box 1 through the sliding of the first slide rod 3 and the first slideway 2. Pull out the second slide rod 12 in the second slideway 11. Place the high-temperature valve between the two clamps 15. Rotate the threaded sleeve 14, and the two groups of clamps 15 approach each other to clamp and fix the high-temperature valve. Close the box door 4 on the heating box 1. Turn on the heating plate 51 and the motor 6. The output end of the motor 6 drives the first belt pulley 7 to rotate. Through the transmission of the transmission belt 9, the second belt pulley 8 rotates accordingly. The second slideway 11 rotates with the rotation of the second belt pulley 8 and the rotating block 10. The high-temperature valve to be detected rotates outside the heating plate 51 and is evenly heated, improving the accuracy of valve detection.
