Specific embodiments

[0019] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0020] Please refer to Figures 1 - 5 , where Figure 1 is the overall structural schematic diagram of the present utility model; Figure 2 is the front view of the overall of the present utility model; Figure 3 is Figure 2 a sectional view of Figure 4 is Figure 2 an enlarged view of location B in Figure 5 is Figure 3 an enlarged view of location C in

[0021] The present utility model provides an elbow structure with a transition ramp: including a sound - damping groove 1 and a smooth transition mechanism. The transition ramp elbow 2 includes a first inclined section 4, a second inclined section 5, a third inclined section 6 and two connection sections 7. The connection assembly 3 includes an inlet connection pipe 8, an outlet connection pipe 9, two sealing rings 10, a plurality of connection blocks 11, two limit snap rings 14, and two flanges 15. The flange 15 includes a limit collar 16, a flange plate 17 and a plurality of reinforcing ribs 18. By the foregoing solution, the problem that the existing elbows do not have a transition ramp is solved. When transporting materials, the friction increment at the turning point is large, the transportation efficiency is low, and the transportation effect of the entire pipeline is reduced.

[0022] For this specific embodiment, the sound - damping groove 1 is arranged inside the transition ramp - type elbow 2. The second inclined section 5 is fixedly connected to one end of the first inclined section 4, and the third inclined section 6 is fixedly connected to the end of the second inclined section 5 away from the first inclined section 4. The two connecting sections 7 are respectively fixedly connected to the first inclined section 4 and the third inclined section 6, and are respectively located at the ends of the first inclined section 4 and the third inclined section 6 away from the second inclined section 5. The connecting assembly 3 is arranged on the two connecting sections 7. When using the elbow structure, the elbow is connected to the pipelines at both ends through the connecting assembly 3. Materials enter the first inclined section 4 from the connecting assembly 3 and the connecting section 7. The turning angle of this section is extremely small, and the increased friction is extremely small. Then it enters the second inclined section 5, where the turning angle is very small and the increased friction is very small. Then it enters the third inclined section 6, where the increased friction is relatively small. Finally, it is discharged from the connecting section 7 and the connecting assembly 3 at the third inclined section 6, completing the pipeline turning. And under the action of the sound - damping groove 1, the transition ramp - type elbow 2 will not generate obvious noise. The sound - damping groove 1 has been fully explained in the prior art "CN205859460U An Elbow", so no more elaboration will be made here.

[0023] Among them, the inlet connecting pipe 8 is fixedly connected to the connecting section 7 located in the first inclined section 4 and is located at the end away from the first inclined section 4. The outlet connecting pipe 9 is fixedly connected to the other connecting section 7 and is located at the end away from the third inclined section 6. When using the elbow, the water inlet pipeline is communicated with the inlet connecting pipe 8, and the water outlet pipeline is communicated with the outlet connecting pipe 9, so that the pipeline to be turned is communicated with the transition ramp - type elbow 2 through the two connecting sections 7 to achieve turning.

[0024] Secondly, both the inlet connecting pipe 8 and the outlet connecting pipe 9 are provided with sealing grooves 12. The inlet connecting pipe 8 is further provided with a plurality of connecting grooves 13. The two sealing rings 10 are respectively arranged in the two sealing grooves 12. A plurality of connecting blocks 11 are fixedly connected to the end of the outlet connecting pipe 9 away from the connecting section 7. When connecting the pipelines, the water injection pipeline is engaged with the inlet connecting pipe 8 through the plurality of connecting grooves 13, and the drainage pipeline is engaged with the outlet connecting pipe 9 through the plurality of connecting blocks 11, making the connection between the transition ramp - type elbow 2 and the two pipelines more firm. The two sealing rings 10 can seal the connection between the transition ramp - type elbow 2 and the pipelines, and there will be no resource leakage.

[0025] Meanwhile, the two limiting snap rings 14 are respectively fixedly connected to the surfaces of the inlet connecting pipe 8 and the outlet connecting pipe 9, and each flange 15 is arranged on each limiting snap ring 14. When connecting the transition ramp elbow 2 to the pipeline, rotate the two flanges 15, and when the positions of the screw holes on them are appropriate, connect them to the pipeline through bolts.

[0026] Finally, the limiting collar 16 is rotatably connected to the surface of the limiting snap ring 14, the flange plate 17 is fixedly connected to the limiting snap ring 14 and rotatably connected to one end of the limiting snap ring 14. A plurality of reinforcing ribs 18 are fixedly connected between the limiting collar 16 and the flange plate 17. When rotating the flange 15, the limiting collar 16 rotates on the surface of the limiting snap ring 14, driving the flange plate 17 to rotate, so as to adjust the position of the screw holes on the flange plate 17. At the same time, the plurality of reinforcing ribs 18 can make the connection between the flange plate 17 and the limiting collar 16 more firm and not easily damaged.

[0027] When using the elbow structure, place the transition ramp elbow 2 between two pipelines. Engage the water injection pipeline with the inlet connecting pipe 8 through multiple connecting slots 13, and engage the drainage pipeline with the outlet connecting pipe 9 through multiple connecting blocks 11, making the connection between the transition ramp elbow 2 and the two pipelines more secure. The two sealing rings 10 can seal the connection between the transition ramp elbow 2 and the pipelines, preventing resource leakage. Subsequently, rotate the flange 15. The limit collar 16 rotates on the surface of the limit snap ring 14, driving the flange plate 17 to rotate, thereby adjusting the position of the screw holes on the flange plate 17. At the same time, multiple reinforcing ribs 18 can make the connection between the flange plate 17 and the limit collar 16 more secure and less likely to be damaged. At this time, the transition ramp elbow 2 is completely fixed to the two pipelines. When transporting materials, the materials enter from the injection pipeline, pass through the inlet connecting pipe 8 and the connecting section 7 into the first inclined section 4. The turning angle of this section is extremely small, and the friction force increased due to the turning of the materials is extremely small. Subsequently, it enters the second inclined section 5, where the turning angle is very small, and the friction force increased due to the turning of the materials is very small. Then it enters the third inclined section 6, where the friction force increased due to the turning of the materials is relatively small. Finally, it is discharged from the connecting section 7 and the outlet connecting pipe 9 at the third inclined section 6 and enters the discharge pipeline, completing the pipeline turning. Since the three turning points of the transition ramp elbow 2 are all large arc angles, the overall friction force generated due to turning is relatively small, and the transportation efficiency is relatively high. Moreover, under the action of the sound-absorbing groove 1, the transition ramp elbow 2 will not generate obvious noise, avoiding the problem that the existing elbows do not have a transition ramp, resulting in a large increase in the friction force at the turning points during material transportation, low transportation efficiency, and reduced transportation effect of the entire pipeline, achieving the effect of improving the pipeline transportation efficiency.
