[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] Example 1:

[0030] Please see Figures 1-5 A heat treatment device for valve processing includes a treatment box 1, a storage mechanism, a hot air circulation mechanism, and a closing mechanism. The storage mechanism includes a shelf 2 and a handle 3. The shelf 2 is installed inside the treatment box 1 and slidably connected to the treatment box 1. The handle 3 is installed inside the shelf 2 and slidably connected to the shelf 2. A connecting rod 4 is installed on the handle 3. One end of the connecting rod 4 is rotatably connected to the handle 3. A fixing rod 5 is installed on the connecting rod 4. The fixing rod 5 is rotatably connected to one end of the connecting rod and cooperates with the treatment box 1. The hot air circulation mechanism includes a fan 6 and a nitrogen generator 7. The fan 6 is fixedly installed at the rear end of the treatment box 1. The nitrogen generator 7 is fixedly connected to the fan 6. A return air component 8 and an air inlet component 9 are installed on the fan 6. The air inlet component 9 is installed at the bottom of the treatment box 1, and the return air component 8 is installed at the top of the treatment box 1.

[0031] In this embodiment, the storage mechanism includes a shelf 2 and a handle 3. In use, the valve assembly that needs to be heat-treated can be placed into the shelf 2 first. Then, the shelf 2 can be installed on the tray 13 of the processing box 1. When the shelf 2 is placed on the tray 13, the mounting block 16 can be slidably connected to the mounting groove 14. After the shelf 2 is completely placed on the tray 13, the handle 3 can be pressed directly to make the positioning hole 18 on the handle 3 slidably connected to the positioning rod 17 on the shelf 2. During this process, the position of the handle 3 changes, causing the position of the connecting rod 4 to change, thereby pushing the fixing rod 5 into the first locking hole 15 to fix the position of the shelf 2.

[0032] In this embodiment, the hot air circulation mechanism includes a fan 6 and a nitrogen generator 7. In use, when the cover 10 is closed, the oxygen-containing air inside the processing chamber 1 can be discharged. The first control valve 21 on the connecting pipe 19 is closed, while the second control valve 22 on the exhaust pipe 20 is opened, and the third control valve 23 of the nitrogen generator 7 is activated. At this time, under the action of the connecting pipe 19, the nitrogen generator 7 pushes nitrogen into the processing chamber 1 through the air inlet 9 and discharges oxygen-containing air through the exhaust pipe 20. After the air inside the processing chamber 1 is discharged, the first control valve 21 is opened, and the second control valve 22 and the third control valve 23 are closed. The heating plate 27 installed inside the processing chamber 1 works, so that the nitrogen inside the processing chamber 1 is heated. The fan 6 also starts to run, so that the heated air inside the processing chamber 1 can circulate inside the processing chamber 1 through the air inlet 9, the return air 8, and the connecting pipe 19.

[0033] In this embodiment, the closing mechanism includes a closing cover 10 and a rotating rod 11. In use, after the shelf 2 is fixed inside the processing box 1, the closing cover 10 can be closed, and the rotating rod 11 installed on the closing cover 10 can be rotated. At this time, the screw 25 on the rotating rod 11 is connected to the fixing frame 12, and the fixing frame 12 begins to slide on the closing cover 10. Under the action of the limiting frame 26, the sliding of the fixing frame 12 is more stable. Finally, the fixing frame 12 is connected to the second locking hole 24, so that the position of the closing cover 10 is fixed.

[0034] Example 2:

[0035] In summary, during use, the valve assembly requiring heat treatment can first be placed in the shelf 2. Then, the shelf 2 can be installed on the tray 13 of the processing box 1. When placing the shelf 2 on the tray 13, the mounting block 16 can be slidably connected to the mounting groove 14. After the shelf 2 is fully placed on the tray 13, the handle 3 can be pressed directly, causing the positioning hole 18 on the handle 3 to slide into the positioning rod 17 on the shelf 2. During this process, the position of the handle 3 changes, causing the position of the connecting rod 4 to change, thereby pushing the fixing rod 5 into the first locking hole 15 to fix the position of the shelf 2. After the shelf 2 is fixed, the closing cover 10 can be closed, and the rotating rod 11 installed on the closing cover 10 can be rotated. At this time, the screw 25 on the rotating rod 11 is connected to the fixing bracket 12, and the fixing bracket 12 begins to slide on the closing cover 10. Under the action of the limiting bracket 26, the fixing bracket 12 is fixed. The fixed frame 12 slides more stably, and finally the fixed frame 12 is connected with the second locking hole 24 to fix the position of the closed cover 10. When the closed cover 10 is closed, the oxygen-containing air inside the processing box 1 can be discharged. The first control valve 21 on the connecting pipe 19 is closed, while the second control valve 22 on the exhaust pipe 20 is opened, and the third control valve 23 of the nitrogen generator 7 is activated. At this time, under the action of the connecting pipe 19, the nitrogen generator 7 pushes nitrogen into the processing box 1 through the air inlet 9 and discharges oxygen-containing air through the exhaust pipe 20. After the air inside the processing box 1 is discharged, the first control valve 21 is opened, and the second control valve 22 and the third control valve 23 are closed. The heating plate 27 installed inside the processing box 1 works, so that the nitrogen inside the processing box 1 is heated. The fan 6 also starts to run, so that the heated air inside the processing box 1 can circulate inside the processing box 1 through the air inlet 9, the return air 8 and the connecting pipe 19.

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
