[0025] Example 1: A steel-lined rubber composite pipe, such as Figure 1-Figure 4 As shown, it includes an anti-corrosion shell 1, a first flange 2, and a second flange 12 arranged at one end of the anti-corrosion shell 1. The surface of the anti-corrosion shell 1 is installed with a plug-in connector 9, and one side surface of the plug-in connector 9 is installed with a plurality of screw rods 11. The surface of the first flange 2 is installed with a plurality of fixing rods 5, and one side surface of the second flange 12 is installed with a plurality of plug-in rods 13. When two steel-lined rubber composite pipes are connected to each other, the anti-corrosion shell 1 on the outside can ensure the corrosion resistance of the pipe. The second flange 12 on one of the composite pipes is connected to the first flange 2 of the other composite pipe. The plug-in is carried out, and the plug-in rod 13 on the second flange 12 passes through the first plug-in hole 7 opened on the surface of the first flange 2. The fixing rod 5 on the surface of the first flange 2 is rotated and plugged into the inside of the plug-in rod 13 to form the first pipeline connection. After the fixing rod 5 and the plug-in rod 13 form a plug-in structure, the screw rod 11 is threadedly screwed through the plug-in part 9 and then formed with the second threaded hole 6 opened on the surface of the fixing rod 5 to form a threaded connection and installation, thereby forming a secondary pipeline connection and fixation, thereby improving the connection airtightness of the two steel-lined rubber pipes, so as to achieve the effect of improving the installation efficiency of the steel-lined rubber composite pipe.

[0026] like Figure 1-Figure 4As shown, the second flange 12 is fixedly installed with the anti-corrosion shell 1, and a sealing tube 8 is fixedly installed on one side surface of the second flange 12. Several fixed blocks 3 are installed on the surface of the second flange 12. A rotating rod 18 is rotatably installed inside the fixed block 3, and a rotating block 4 is installed on the surface of the rotating rod 18. A fixing rod 5 is fixedly installed on the surface of the rotating block 4. The anti-corrosion shell 1 located on the outside can ensure the corrosion resistance of the pipeline. The presence of the sealing tube 8 can ensure the airtightness of the connection between the first flange 2 and the second flange 12 after installation and connection. The rotating rod 18 can be rotatably installed inside the fixed block 3. Driven by the rotating rod 18, the rotating block 4 drives the fixing rod 5 to be plugged into the inside of the plug-in rod 13, thereby forming the effect of the first pipeline plug-in fixation.

[0027] like Figure 1-Figure 4 As shown, a plurality of first plug holes 7 are opened on the surface of the first flange 2, and a plurality of plug rods 13 are fixedly installed on the surface of the second flange 12. A second plug hole 14 is opened on the surface of the plug rod 13. The second flange 12 is fixedly installed on one side surface of the anti-corrosion shell 1, and a plurality of first threaded holes 10 are opened on the surface of the plug-in component 9. The screw rod 11 is threadedly connected to the upper surface of the first threaded hole 10, and a second threaded hole 6 is opened on the surface of the fixing rod 5. The screw rod 11 passes through the plug-in component 9 and is threadedly connected to the second threaded hole 6 opened on the surface of the fixing rod 5. A second plug hole 14 can be opened on the surface of the plug-in component 13, and the second plug hole 14 can form a first plug-in fixation with the fixing rod 5. Through the provision of the plug-in component 9, a first threaded hole 10 can be opened on its surface. The screw rod 11 is threadedly screwed through the first threaded hole 10 to pass through the plug-in component 9 and then is threadedly fixed with the second threaded hole 6 opened on the surface of the fixing rod 5, thereby achieving the effect of secondary pipeline connection and fixation, thereby improving the sealing of the pipeline connection and improving the pipeline connection efficiency.

[0028] Example 2: A steel-lined rubber composite pipe, such as Figure 1-Figure 4 As shown, a steel lining frame 15 is installed inside the anti-corrosion shell 1, and an adhesive layer 16 is installed inside the steel lining frame 15. The steel lining frame 15 installed inside the anti-corrosion shell 1 can increase the impact strength of the overall composite pipe, thereby increasing the service life of the pipeline.

[0029] like Figure 1-Figure 4 As shown, the steel lining skeleton 15 is fixedly installed inside the anti-corrosion shell 1, and an adhesive layer 16 is fixedly installed inside the steel lining skeleton 15. A rubber layer 17 is fixedly installed inside the adhesive layer 16. Through the adhesive layer 16 installed inside the steel lining skeleton 15, the rubber layer 17 can be installed inside the adhesive layer 16. The presence of the rubber layer 17 can ensure that the lubricity of the inner wall of the composite pipe is increased when the composite pipe is transported in the pipeline, and it can transport corrosive media, thereby achieving the effects of corrosion resistance and high lubricity.

[0030] Working principle: When two steel-lined rubber composite pipes are connected, the second flange 12 on one of the composite pipes is plugged into the first flange 2, and the plug rod 13 on the second flange 12 passes through the first plug hole 7 opened on the surface of the first flange 2. The fixing rod 5 on the surface of the first flange 2 is rotated and plugged into the plug rod 13 to form the first pipe connection. After the fixing rod 5 and the plug rod 13 form a plug-in structure, the screw rod 11 is threadedly screwed through the plug-in piece 9 and then formed into a threaded connection and installation with the second threaded hole 6 opened on the surface of the fixing rod 5, thereby forming a secondary pipe connection and fixing, thereby improving the connection airtightness of the two steel-lined rubber pipes, so as to achieve the effect of improving the installation efficiency of the steel-lined rubber composite pipe. The anti-corrosion shell 1 on the outside can ensure the corrosion resistance of the pipeline. The presence of the sealing tube 8 can ensure that the connection between the two composite pipes is airtight after the first flange 2 and the second flange 12 are installed and connected. The rotating rod 18 can be rotatably installed inside the fixed block 3. Driven by the rotating rod 18, the rotating rod The movable block 4 drives the fixing rod 5 to be inserted into the inside of the plug rod 13, thereby forming the effect of the first pipe plug-in fixation. A second plug-in hole 14 can be opened on the surface of the plug rod 13, and the second plug-in hole 14 can form a first plug-in fixation with the fixing rod 5. Through the provided plug-in piece 9, a first threaded hole 10 can be opened on its surface, and the screw rod 11 is threadedly screwed through the first threaded hole 10 to penetrate the plug-in piece 9 and then form a threaded screw fixation with the second threaded hole 6 opened on the surface of the fixing rod 5, which plays the effect of secondary pipe connection and fixation, thereby improving the sealing of the pipeline connection and improving the pipeline connection efficiency. The steel lining skeleton 15 installed inside the anti-corrosion shell 1 can increase the impact strength of the overall composite pipe, thereby increasing the service life of the pipeline. By installing the adhesive layer 16 inside the steel lining skeleton 15, the rubber layer 17 can be installed inside the adhesive layer 16. The presence of the rubber layer 17 can ensure that the lubricity of the inner wall of the composite pipe is increased when the composite pipe is transported in the pipeline, and it can transport corrosive media, thereby playing the effect of corrosion resistance and high lubricity.
