Description

Technical Field

[0001] The utility model relates to the technical field of conveying pipelines, in particular to a spliced ​​conveying pipeline. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid is pressurized by a blower, compressor, pump and boiler, and then flows from the high-pressure part of the pipeline to the low-pressure part. It can also be conveyed by the fluid's own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, gas supply, agricultural irrigation, etc. Pipelines are also used in the transportation of rice. Due to the long distance of pipeline transportation, it is usually necessary to splice multiple pipelines. The existing pipeline splicing method is usually to connect and fix with flange bolts. The splicing method is relatively simple. When the bolts are loose, gaps are likely to appear at the joints of the pipeline, and the sealing is poor. For this reason, we propose a spliced ​​conveying pipeline. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a spliced ​​conveying pipeline, which is convenient for the splicing of pipelines and has multiple limiting mechanisms, so that the splicing of pipelines is more stable and firm, the internal structure is not easy to loosen, and the sealing is better, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spliced ​​delivery pipeline, comprising a pipeline, a bolt and an internal thread ring;

[0005] Pipes: There are two of them. The opposite inner ends of the two pipes are both provided with flanges. Bolts pass through the corresponding through holes inside the flanges from left to right and are threadedly connected with nuts at the right end. The left end face of the flange on the left is evenly provided with hexagonal holes matching with the bolts, and the right end face of the flange on the right is evenly provided with limiting mechanisms matching with the nuts.

[0006] Internal thread ring: It is rotatably connected to the outer side of the flange on the left. The outer side of the flange on the right is provided with threads that cooperate with the internal thread ring, which is convenient for pipe splicing. It has multiple limiting mechanisms to make the pipe splicing more stable and firm, the internal structure is not easy to loosen, and the sealing is better.

[0007] Furthermore, the limiting mechanism includes a spring, a plug column and a limiting ring. The left side of the limiting ring is evenly provided with plug columns, and the plug columns are respectively inserted into the sockets evenly provided on the right end surface of the flange on the right side. A spring is provided in the groove provided at the left end of the plug column. The left end of the spring is fixedly connected to the inner wall of the corresponding socket. The right end of the bolt is located inside the corresponding limiting ring. The limiting ring and the relative inner side surfaces of the nut are provided with teeth at equal angles, which can effectively prevent the nut from loosening.

[0008] Furthermore, the outer ends of the plug posts are clamped with clamping rings, which are located in the gap between the flange on the right and the limiting ring, and play a limiting role on the limiting ring.

[0009] Furthermore, the outer side surface of the internal threaded ring is symmetrically rotatably connected with a clamp, and the outer ends of the two clamps are fixedly connected by screws. The left and right sides of the two clamps are symmetrically provided with limiting hooks that cooperate with the flange to further limit the flange.

[0010] Furthermore, inclined plates are symmetrically provided at the outer ends of the clamps to prevent the outer ends of the clamps from being deformed.

[0011] Furthermore, it also includes a connecting pipe, which is clamped between two flanges, and the left and right ends of the connecting pipe are respectively inserted into the inside of the pipe on the same side. The inside of the two pipes is provided with a rubber ring that cooperates with the connecting pipe to ensure the sealing of the pipe connection.

[0012] Furthermore, the interior of the pipeline is provided with a wear-resistant coating, and the wear-resistant coating is a polyethylene wear-resistant coating, which greatly improves the wear resistance of the interior of the pipeline.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. Connect the two pipes to be spliced, and rotate the internal thread ring at the same time to make the internal thread ring threadedly connected with the flange on the right, and then fix the two flanges. Use screws to connect and fix the outer ends of the two clamps, so that the limiting hooks on the outside of the clamps contact the flange on the same side, and further limit the flange to ensure the firmness and stability of the pipe splicing.

[0015] 2. Use bolts to pass through the corresponding through holes of the two flanges and make the right end of the bolt located inside the limit ring. Then turn the nut at the right end of the bolt to make the teeth on the left end of the nut cooperate with the teeth on the right side of the limit ring. Continue to turn the nut, the limit ring moves to the left, and the plug post slides along the plug hole on the right end face of the flange on the right. The spring plays an elastic supporting role for the limit ring, and the plug post can limit the rotation of the limit ring. When the limit ring moves to a certain distance from the flange on the right, the clamping ring is clamped to the right end of the plug post, thereby limiting the limit ring, and then limiting the nut to prevent the subsequent loosening of the nut and make the splicing of the pipeline more secure.

[0016] 3. The two flanges are used to fix the connecting pipes in position, and at the same time, the two ends of the connecting pipes are respectively inserted into the pipes on the same side. The rubber rings inside the connecting pipes and the pipes cooperate to seal the connection between the connecting pipes and the pipes, thereby ensuring the sealing of the pipe connection and providing certain support for the pipe connection.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 ,This embodiment provides a technical solution: a spliced ​​delivery pipeline, including a pipeline 1, a bolt 4 and an internal thread ring 10;

[0024] Pipeline 1: There are two of them. The opposite inner ends of the two pipes 1 are each provided with a flange 3. The bolt 4 passes through the corresponding through hole inside the flange 3 from left to right and is threadedly connected with a nut 5 at the right end. The left end face of the flange 3 on the left is evenly provided with an inner hexagonal hole 6 that cooperates with the bolt 4. The right end face of the flange 3 on the right is evenly provided with a limiting mechanism 2 that cooperates with the nut 5. The limiting mechanism 2 includes a spring 21, a plug column 22 and a limiting ring 23. The left side face of the limiting ring 23 is evenly provided with a plug column 22. The plug columns 22 are respectively inserted into the evenly provided sockets on the right end face of the flange 3 on the right. A spring 21 is provided in the groove provided at the left end of the plug column 22. The left end of the spring 21 is fixedly connected to the corresponding inner wall of the socket. The right end of the bolt 4 is located inside the corresponding limiting ring 23. The limiting ring 23 and the relative inner side faces of the nut 5 are evenly angled. The outer ends of the plug posts 22 are all clamped with snap rings 13, which are located in the gap between the flange 3 and the limiting ring 23 on the right side. The bolt 4 is passed through the corresponding through holes of the two flanges 3 and the right end of the bolt 4 is located inside the limiting ring 23. Then the nut 5 at the right end of the bolt 4 is turned to make the teeth at the left end of the nut 5 cooperate with the teeth on the right side of the limiting ring 23. The nut 5 is continued to be turned, and the limiting ring 23 moves to the left. The plug post 22 slides along the insertion hole on the right end face of the flange 3 on the right side. The spring 21 plays an elastic supporting role for the limiting ring 23, and the plug post 22 can limit the rotation of the limiting ring 23. When the limiting ring 23 moves to a certain distance from the flange 3 on the right side, the snap ring 13 is clamped to the right end of the plug post 22, thereby limiting the limiting ring 23, and then limiting the nut 5 to prevent the subsequent loosening of the nut 5.

[0025] The inner threaded ring 10 is rotatably connected to the outer side of the flange 3 on the left, and the outer side of the flange 3 on the right is provided with a screw thread that cooperates with the inner threaded ring 10. The two pipes 1 that need to be spliced ​​are docked, and the inner threaded ring 10 is rotated at the same time to make the inner threaded ring 10 threadedly connected to the flange 3 on the right, thereby fixing the two flanges 3. The outer side of the inner threaded ring 10 is symmetrically rotated and connected with a clamp 11. The outer ends of the two clamps 11 are fixedly connected by screws 12. The left and right sides of the two clamps 11 are symmetrically provided with limiting hooks 112 that cooperate with the flange 3. The screws 12 are used to connect and fix the outer ends of the two clamps 11, so that the limiting hooks 112 on the outer sides of the clamps 11 contact the flange 3 on the same side, further limiting the flange 3, and ensuring that the pipes 1 are firmly and stably spliced. The outer ends of the clamps 11 are symmetrically provided with inclined plates 111, which can prevent the ends of the clamps 11 from deforming when the clamps 11 are fixed.

[0026] Wherein: it also includes a connecting pipe 8, the connecting pipe 8 is clamped between the two flanges 3, the left and right ends of the connecting pipe 8 are respectively inserted into the inside of the pipe 1 on the same side, and the inside of the two pipes 1 is provided with a rubber ring 9 that cooperates with the connecting pipe 8. The two flanges 3 are fixed to limit the connecting pipe 8, and at the same time, the two ends of the connecting pipe 8 are respectively inserted into the inside of the pipe 1 on the same side. The connecting pipe 8 cooperates with the rubber ring 9 inside the pipe 1 to seal the connection between the connecting pipe 8 and the pipe 1, thereby ensuring the sealing of the connection of the pipe 1, and at the same time, it can play a certain supporting role for the connection of the pipe 1. The inside of the pipe 1 is provided with a wear-resistant coating 7, and the wear-resistant coating 7 is a polyethylene wear-resistant coating, which greatly improves the wear resistance of the inner wall of the pipe 1.

[0027] The working principle of a spliced ​​conveying pipeline provided by the utility model is as follows: when conveying rice, two pipelines 1 that need to be spliced ​​are docked, and the internal threaded ring 10 is rotated at the same time, so that the internal threaded ring 10 is threadedly connected with the flange 3 on the right side, and then the two flanges 3 are fixed. At the same time, the two flanges 3 fix the connecting pipeline 8, so that the two ends of the connecting pipeline 8 are respectively inserted into the inside of the pipeline 1 on the same side, and the connecting pipeline 8 cooperates with the rubber ring 9 inside the pipeline 1 to seal the connection between the connecting pipeline 8 and the pipeline 1, and then the bolt 4 is used to pass through the corresponding through holes of the two flanges 3 and make the right end of the bolt 4 located inside the limiting ring 23, and then the nut 5 at the right end of the bolt 4 is rotated so that the teeth of the left end of the nut 5 are aligned with the right side surface of the limiting ring 23. The teeth of the nut 5 are matched, and the nut 5 continues to be rotated. The limit ring 23 moves to the left, and the plug post 22 slides along the insertion hole on the right end face of the flange 3 on the right side. The spring 21 plays an elastic supporting role for the limit ring 23, and the plug post 22 can limit the rotation of the limit ring 23. When the limit ring 23 moves to a certain distance from the flange 3 on the right side, the clamping ring 13 is clamped to the right end of the plug post 22, thereby limiting the limit ring 23 and then limiting the nut 5 to prevent the subsequent loosening of the nut 5. The screw 12 is used to connect and fix the outer end of the clamping hoop 11 symmetrically rotated and connected to the outer side of the internal threaded ring 10, so that the limit hook 112 on the outside of the clamping hoop 11 contacts the flange 3 on the same side, further limiting the flange 3 to ensure the firm and stable splicing of the pipeline 1.
