[0022] refer to Figures 1 to 4 This embodiment of a flange with a reinforced structure includes a flange body 1. A reinforcing plate 2 is fixedly connected to the top of the flange body 1. A connecting hole 3 is opened at the top of the flange body 1, located on the inner side close to the reinforcing plate 2. A support block 5 is threadedly connected to the top of the flange body 1. A second threaded hole 9 is opened on one side of the support block 5. A screw 10 is threadedly connected to the inner side of the second threaded hole 9. A rotating shaft 11 is fixedly connected to the other side of the screw 10. A clamping plate 12 is rotatably connected to the other side of the rotating shaft 11. The position of the clamping plate 12 corresponds to the position of the reinforcing plate 2. A positioning hole 4 is opened at the top of the flange body 1, located on the four sides near the corners of the top of the flange body 1. In use, the flange body 1 is used to... The positioning element that matches the positioning hole 4 can limit the position of the flange body 1 to prevent the flange body 1 from shifting. The connection hole 3 facilitates the subsequent connection of the pipeline. Its reinforcing plate 2 can effectively improve the stability of the pipeline connection point. After the pipeline is connected, the user can turn the screw 10, and the rotating shaft 11 can make the end of the screw 10 rotate in place. The clamping plate 12 will be pushed or pulled accordingly. The mutual clamping of the two clamping plates 12 can provide secondary clamping and limitation on the outer wall of the connected pipeline, thereby effectively improving the connection strength of the flange to the pipeline. At the same time, the clamping of the clamping plate 12 can also provide secondary support and traction for the pipeline, which can effectively prevent the pipeline connection point from being bent.

[0023] refer to Figure 1 and Figure 2A fixing block 6 is fixedly connected to one side of the support block 5. The bottom end of the fixing block 6 is attached to the top end of the flange body 1. A first screw hole 7 is opened at the top end of the fixing block 6. The first screw hole 7 extends into the interior of the flange body 1. A bolt 8 is threadedly connected to the inside of the first screw hole 7. The bottom end of the bolt 8 is threaded into the interior of the flange body 1 through the first screw hole 7. Due to the presence of the bolt 8, the bolt 8 can be screwed in to effectively fix the fixing block 6, thereby effectively limiting the position of the support block 5 to prevent the support block 5 from shifting. When the support block 5 needs to be disassembled later, the bolt 8 can be unscrewed. It also facilitates the user to maintain the structure on the support block 5 later.

[0024] refer to Figure 2 A telescopic rod 14 is fixedly connected to the other side of the support block 5. The other side of the telescopic rod 14 is fixedly connected to one side of the clamping plate 12. The screw 10 is located on the inner side close to the telescopic rod 14. The telescopic rod 14 includes a movable rod and a sleeve rod. The movable rod is sleeved on the inner side of the sleeve rod. Due to the presence of the telescopic rod 14, the telescopic rod 14 can provide secondary support and traction to the other side of the clamping plate 12 without hindering the movement of the clamping plate 12, thereby effectively improving the stability of the clamping plate 12 position adjustment.

[0025] refer to Figure 2 A rubber pad 13 is fixedly connected to the other side of the clamping plate 12. The rubber pad 13 is one centimeter thick and covers the other side of the clamping plate 12. The position of the rubber pad 13 corresponds to the position of the connection hole 3. Due to the presence of the rubber pad 13, the rubber pad 13 has good anti-slip ability and rubber elasticity. While improving the stability of the pipe clamping point, it can also prevent the outer wall of the pipe from being bumped, thereby effectively improving the safety of the clamping plate 12.

[0026] refer to Figure 1 and Figure 4 The flange body 1 has a reinforcing layer 15 inside. The thickness of the reinforcing layer 15 is one centimeter. The reinforcing layer 15 is made of stainless steel. Due to the presence of the reinforcing layer 15, the stainless steel material has strong corrosion resistance and good low-temperature toughness, which can effectively improve the internal structural strength of the flange body 1.

[0027] refer to Figure 4 The flange body 1 has a heat-resistant layer 16 inside, which is five millimeters thick. The reinforcing layer 15 is located on the inner side of the heat-resistant layer 16. The heat-resistant layer 16 is made of ceramic material. Due to the presence of the heat-resistant layer 16, the ceramic material has extremely high heat resistance and can be used in flange forgings with good heat resistance. It is usually the main component of the heat-resistant layer 16. For example, in some flange forgings with good heat resistance, the ceramic material layer accounts for 62%-68%, which is suitable for high-temperature environments and can effectively improve the high-temperature resistance of the flange body 1.

[0028] refer to Figure 4 The flange body 1 has an internal pressure-resistant layer 17 with a thickness of one centimeter. The heat-resistant layer 16 is located on the inner side of the pressure-resistant layer 17. The pressure-resistant layer 17 is made of metal material. Due to the presence of the pressure-resistant layer 17, the metal material can withstand extremely high temperatures and pressures, making it suitable for harsh working conditions such as high temperature, high pressure, and strong corrosion, and effectively improving the service life of the flange body 1.

[0029] Operating principle and advantages: During use, the positioning element matching the positioning hole 4 can limit the position of the flange body 1 to prevent displacement. The connection hole 3 facilitates subsequent pipe connection. The reinforcing plate 2 effectively improves the stability of the pipe connection point. After the pipe connection is completed, the user can tighten the screw 10, and the rotating shaft 11 can rotate the end of the screw 10 in place. The clamping plate 12 will be pushed or pulled accordingly. The mutual clamping of the two clamping plates 12 can provide secondary clamping and limitation on the outer wall of the connected pipe, thereby effectively improving the connection strength of the flange to the pipe. At the same time, the clamping of the clamping plate 12 can also provide secondary support and traction for the pipe, effectively preventing the pipe connection point from being bent. Due to the presence of bolt 8, tightening bolt 8 can effectively fix the position of the fixing block 6, thereby effectively limiting the position of the support block 5 to prevent displacement. When the support block 5 needs to be disassembled later, simply unscrew bolt 8. This also facilitates the user's later maintenance of the structure on the support block 5. The presence of the telescopic rod 14 allows for secondary support and traction on the other side of the clamping plate 12 without hindering its movement, thus effectively improving the stability of the clamping plate 12's position adjustment. The presence of the rubber pad 13 provides excellent anti-slip properties and elasticity, enhancing the stability of the pipe clamping while preventing damage to the pipe's outer wall, thereby improving the safety of the clamping plate 12. The presence of the reinforcing layer 15, made of stainless steel with strong corrosion resistance and good low-temperature toughness, effectively improves the internal structural strength of the flange body 1. The presence of the heat-resistant layer 16, made of ceramic material with extremely high heat resistance, is suitable for use in heat-resistant flange forgings and is typically a major component of the heat-resistant layer 16, effectively improving the flange body 1's high-temperature resistance. The presence of the pressure-resistant layer 17 allows the metal material to withstand extremely high temperatures and pressures, making it suitable for harsh working conditions such as high temperature, high pressure, and strong corrosion, effectively extending the service life of the flange body 1.
