[0002] A propane dehydrogenation reactor is a chemical equipment used to convert propane into propylene. This process is crucial for the production of plastics and other chemicals. In the reactor, propane undergoes a dehydrogenation reaction under the action of a catalyst to produce propylene, accompanied by the release of hydrogen. To ensure the safe and efficient conduct of the reaction, the reactor needs to be equipped with a series of valves to control the inflow and outflow of fluids and to regulate pressure and flow rate. Valves for propane dehydrogenation reactors are specially designed for this special operating condition. They must not only be able to withstand high temperature and high pressure environments, but also have excellent sealing performance to prevent media leakage.

[0003] The problem with existing technology is that existing equipment generally uses flange bolts or welding for connection, which makes the installation and disassembly process complicated, time-consuming and labor-intensive. It not only requires high precision of manual labor, but also easily causes leakage risk due to misalignment. At the same time, it brings a lot of inconvenience to subsequent maintenance, ultimately resulting in low overall construction efficiency. Summary of the Invention

Detailed Implementation

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, the connection structure of a valve for a propane dehydrogenation reactor provided in this embodiment of the present invention includes a first connecting pipe 1 and a second connecting pipe 2. The second connecting pipe 2 is provided on the left side of the first connecting pipe 1. A first docking plate 3 is fixedly connected to the left side of the first connecting pipe 1. A second docking plate 4 is fixedly connected to the right side of the second connecting pipe 2. The first docking plate 3 and the second docking plate 4 cooperate with each other. A valve 5 is fixedly connected to the left side of the second connecting pipe 2.

[0022] refer to Figure 3 The first docking plate 3 has a receiving groove 6 inside its left side. A turntable 7 is placed inside the receiving groove 6. The right side of the turntable 7 is rotatably connected to the right side of the receiving groove 6. A stroke groove 8 is provided at each of the four corners of the right side of the turntable 7. An extension plate 9 is placed at each of the four corners of the right side of the receiving groove 6. The right side of the extension plate 9 is slidably connected to the right side of the receiving groove 6. A slider 10 is fixedly connected to the left side of each extension plate 9. The left side of the slider 10 is slidably connected to the inside of the stroke groove 8.

[0023] By adopting the above solution, a firm connection and automatic locking between the first docking plate 3 and the second docking plate 4 can be achieved by setting the turntable 7 and the extension plate 9, ensuring a stable and reliable mechanical locking after the second docking plate 4 is inserted into the fixing groove 11, thereby enhancing the safety and sealing of the overall structure.

[0024] refer to Figure 2 The four corners of the right side of the second docking plate 4 are provided with fixing grooves 11. The end of the extension plate 9 away from the slider 10 passes through and extends out of the surface of the first docking plate 3. The extension plate 9 is used in conjunction with the fixing grooves 11.

[0025] By adopting the above solution, the fixing groove 11 can be set to achieve a firm limit and mechanical locking between the first docking plate 3 and the second docking plate 4, further enhancing the stability of the connection.

[0026] refer to Figure 4 The first docking plate 3 has a groove 12 inside on the right side. The right side of the turntable 7 extends through and into the groove 12. A gear 13 is placed inside the groove 12. The left side of the gear 13 is fixedly connected to the right side of the turntable 7. The right side of the gear 13 is rotatably connected to the right side of the groove 12. A rack 14 is placed on the top of the gear 13. The left side of the rack 14 is slidably connected to the left side of the groove 12. The gear 13 and the rack 14 are meshed together.

[0027] By adopting the above scheme, the extension and retraction of the extension plate 9 can be precisely controlled by setting gear 13 and rack 14, thereby realizing a fast and accurate connection and locking between the first docking plate 3 and the second docking plate 4, and improving the accuracy of operation.

[0028] refer to Figure 4 A lead screw 15 is placed on the top of the groove 12. The rear end of the lead screw 15 is rotatably connected to the surface of the groove 12. The front end of the lead screw 15 passes through and extends out of the front side of the first mating plate 3. A rotating handle 16 is fixedly connected to the front end of the lead screw 15. A rack 14 is threadedly connected to the surface of the lead screw 15.

[0029] The above solution is adopted: by setting the lead screw 15, the linear motion of the rack 14 can be precisely controlled by manually rotating the handle 16, thereby driving the gear 13 and the turntable 7 to rotate, and finally pushing the extension plate 9 to perform the locking operation.

[0030] refer to Figure 3 Stabilizers 17 are placed at the four corners of the right side of the receiving groove 6. The right side of each stabilizer 17 is fixedly connected to the right side of the receiving groove 6. The extension plates 9 are slidably connected to the inside of the stabilizer 17.

[0031] By adopting the above solution, the stabilizing frame 17 can provide guidance and additional support for the extension plate 9, ensuring its stability and accuracy during movement and avoiding inaccurate locking or structural loosening caused by offset or shaking.

[0032] refer to Figure 1 and Figure 2 A first sealing ring 18 is fixedly connected to the left side of the first mating plate 3, and a second sealing ring 19 is fixedly connected to the right side of the second mating plate 4. The first sealing ring 18 and the second sealing ring 19 are used in conjunction with each other.

[0033] By adopting the above solution, by setting the first sealing ring 18 and the second sealing ring 19, a tight double seal can be formed when the first mating plate 3 and the second mating plate 4 are mated, effectively preventing media leakage and improving the sealing performance and safety of the interface.

[0034] In use, first insert the left side of the first mating plate 3 into the inside of the right side of the second mating plate 4, so that the two fit together. At this time, the first sealing ring 18 and the second sealing ring 19 are in close contact, forming a preliminary seal. Then, use the rotating handle 16 to rotate the lead screw 15. The lead screw 15 drives the rack 14 to move forward. The rack 14 drives the gear 13 to rotate. The gear 13 drives the turntable 7 to rotate. Since the right side of the extension plate 9 is slidably connected to the right side of the receiving groove 6, the extension plate 9 can only move in a predetermined direction. When the turntable 7 rotates, the turntable 7 will push the slider 10 to move through the stroke groove 8. Then the slider 10 pushes the extension plate 9 to move outward. When the extension plate 9 is inserted into the corresponding fixing groove 11, stop rotating the rotating handle 16. At this time, the first mating plate 3 and the second mating plate 4 are firmly connected through the cooperation of the extension plate 9 and the fixing groove 11. At the same time, the first sealing ring 18 and the second sealing ring 19 can ensure the sealing performance at the interface and prevent media leakage.

[0035] In summary, the valve connection structure of this propane dehydrogenation reactor, through the coordinated use of a first connecting pipe 1, a second connecting pipe 2, a first docking plate 3, a second docking plate 4, a valve 5, a receiving tank 6, a turntable 7, a stroke groove 8, an extension plate 9, a slider 10, a fixing groove 11, a groove 12, a gear 13, a rack 14, a lead screw 15, a rotating handle 16, a stabilizing frame 17, a first sealing ring 18, and a second sealing ring 19, solves the problem of existing equipment commonly using flange bolt fixing or welding connection methods, which leads to complex, time-consuming, and labor-intensive installation and disassembly processes. This not only requires high precision from operators but also easily causes leakage risks due to misalignment, while also causing many inconveniences for subsequent maintenance, ultimately resulting in low overall construction efficiency.
