It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figures 1-4 The utility model provides a technical solution: an anti-erosion pipeline, the anti-erosion pipeline comprising: a conveying pipeline 1, a flange fastening assembly 2 is fixedly connected to the right end of the conveying pipeline 1, a right end of the flange fastening assembly 2 is fixedly connected to a right-angle steering tube 4, the upper right end of the right-angle steering tube 4 is fixedly connected to the flange fastening assembly 2, and the upper end of the flange fastening assembly 2 is fixedly connected to the conveying pipeline 1; an anti-erosion elbow assembly is fixedly connected inside the right-angle steering tube 4, the anti-erosion elbow assembly comprises a thickened pipe 3, the inner diameter of the thickened pipe 3 is slightly thicker than that of the conveying pipeline 1, the oil enters from the conveying pipeline 1, changes direction through the anti-erosion elbow assembly and continues to be transported in the conveying pipeline 1, wherein when entering the thickened pipe 3, the flow velocity is reduced due to the increase in cross-section, thereby reducing erosion of the pipeline.

[0020] Example 2: On the basis of Example 1, the inner sleeve of the thickened pipe 3 is provided with an inner buffer pad 8, and the inner side of the inner buffer pad 8 is fixedly connected to a ceramic wear-resistant inner sleeve 9. The inner surface of the ceramic wear-resistant inner sleeve 9 is provided with a number of anti-impact inner patterns 10. The cross section of the anti-impact inner pattern 10 is arc-shaped and fixedly connected to the inner surface of the ceramic wear-resistant inner sleeve 9 along the pipeline direction. The outer side of the inner surface of the ceramic wear-resistant inner sleeve 9 is fixedly connected with an external diverter protrusion 7. The cross section of the external diverter protrusion 7 is arc-shaped. The inner surface of the ceramic wear-resistant inner sleeve 9 is fixedly connected with two internal diverter protrusions 6. The inner end of the right-angle steering tube 4 is fixedly connected to a circumferential array of several spoiler plates 5, and the spoiler 5 It is installed in an inclined shape on the inner surface of the linear pipe at both ends of the right-angle turning pipe 4. When the oil flows into the right-angle turning pipe 4 from the delivery pipe 1, the flow mode of the oil is first changed by the spoiler 5 to prevent the oil from always eroding the same position of the thickened pipe 3. At the same time, the diversion coordination of the external diversion protrusion 7 and the internal diversion protrusion 6 can further prevent the oil from directly impacting and eroding the inside of the pipe when the oil flows, thereby improving the service life of the pipe. The arrangement of the inner buffer pad 8 and the ceramic wear-resistant inner sleeve 9 partially absorbs the intensity of the oil erosion, while increasing the wear resistance of the eroded surface and extending the service life of the pipe.

[0021] In actual use, when the oil flows from the delivery pipe 1 into the right-angle turning pipe 4, the flow pattern of the oil is first changed by the spoiler 5 to prevent the oil from always eroding the same position of the thickened pipe 3. At the same time, the diversion cooperation of the external diversion protrusion 7 and the internal diversion protrusion 6 can further prevent the oil from directly impacting and eroding the inside of the pipe when the oil flows, thereby improving the service life of the pipe. The setting of the inner buffer pad 8 and the ceramic wear-resistant inner sleeve 9 partially absorbs the intensity of the oil erosion, while increasing the wear resistance of the eroded surface and extending the service life of the pipe.
