Description

Technical Field

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

[0002] Traditional pipe connections are made through threaded connections or flange welding. The pipe wall of the threaded connection must reach the thickness required by the national standard before the threads can be made. Therefore, the weight of traditional pipes of the same specification is many times the weight of the flanged connection pipe, which has high economic costs, and the threads need to be made on site, with a long installation period, high labor intensity, and difficulty in disassembly. While the flange welding connection method is used, the pipe wall must also reach the thickness required by the national standard before it can be welded into shape. Therefore, it also has the disadvantage of being many times the weight of the flanged connection pipe, and the pipe must be welded on site, with long working hours, low efficiency, high labor intensity, and the smoke generated during the welding process is harmful to the human body. The installation is slow and the disassembly is inconvenient. Utility Model Content

[0024] See also Figures 1 to 3 , is a fluid conveying pipeline in some embodiments of the utility model. The pipeline conveying process is a process of transporting substances from one place to another through a pipeline. The fluid conveying pipeline is mainly suitable for transporting various liquids, gases and other fluids, and can be used in various industries to transport energy, such as media, water, gas, and oil.

[0025] Specifically, the fluid delivery pipeline includes a plurality of pipe bodies 1, each adjacent pipe body 1 is connected together by a connecting mechanism, and the pipe body 1 is preferably made of aluminum alloy. The use of aluminum alloy makes the pipeline light, corrosion-resistant, and has good hardness and rigidity, which can improve the pipe body 1's ability to resist acid mist and salt mist, and its rust-proof ability, and can reduce the contamination of liquid or fluid. In some other embodiments, the pipe body 1 can also be made of stainless steel, hard PVC or other materials.

[0026] Furthermore, each connecting mechanism includes a connecting piece 2 and multiple assembly components, each of which includes a multi-tooth retaining spring 3, a gasket 4, a sealing ring 5 and a flange 6. The connecting piece 2 can be made of an engineering polymer composite material. The connecting piece 2 is provided with a positioning step 21, a limiting step 22 and a sealing step 23 in sequence along the direction of its interior toward the open end. The positioning step 21 is used to position the axial end face of the tube body 1. The multi-tooth retaining spring 3, the gasket 4 and the sealing ring 5 are sequentially installed on the limiting step 22. The end face of the flange 6 abuts against the sealing step 23. The flange 6 is connected to the connecting piece 2 by a fastener 7, and the fastener 7 can be a bolt.

[0027] It can be understood that the tube body 1 can be inserted into the flange 6 and connected to the connecting piece 2. The flange 6 is provided with a through hole 61 for the tube body 1 to pass through. The outer diameter of the tube body 1 is similar to the diameter of the through hole 61. When the tube body 1 is inserted into the connecting piece 2, the axial end face of the tube body 1 will abut against the positioning step 21, and when the tube body 1 is retracted, it will be locked and clamped by the multi-tooth retaining spring 3, thereby completing the locking connection between the tube body 1 and the connecting piece 2.

[0028] Among them, the connecting piece 2 is an elbow, a straight-through, a tee or a cross-way, and the number of the assembly components can be set according to the structural form of the connecting piece 2. For example, when the connecting piece 2 is an elbow or a straight-through, the number of the assembly components is two; when the connecting piece 2 is a tee, the number of the assembly components is three; when the connecting piece 2 is a cross-way, the number of the assembly components is four.

The multi-toothed circlip 3 includes a circlip body 31 and a plurality of latch teeth 32 integrally formed with the circlip body 31. The plurality of latch teeth 32 are evenly arranged along the circumferential direction of the circlip body 31, and the latch teeth 32 are tilted relative to the circlip body 31. The tilt angle between the latch teeth 32 and the circlip body 31 is preferably 30 degrees, and this tilt angle can be set according to actual assembly requirements and is not specifically limited here. Among them, the direction of the latch teeth 32 is the direction of the flange 6 toward the connecting piece 2, which can realize the function that the tube body 1 will be locked and clamped by the multi-toothed circlip 3 when it is reversed.

[0030] The gasket 4 can be a positioning pressing plate, which can be used to compress the multi-tooth retaining spring 3. The gasket 4 is in a circular ring shape and can be made of an engineering polymer composite material to ensure that it has sufficient rigidity to compress the multi-tooth retaining spring 3.

[0031] The sealing ring 5 is in a circular shape and can be made of EPDM rubber. The sealing ring 5 abuts against the gasket 4 to play a sealing role. After the flange 6 is connected to the connecting piece 2, the flange 6 abuts against the sealing ring 5. In addition, the sealing ring 5 is provided with an inner chamfer 51 and an outer chamfer 52, the radius of the inner chamfer 51 is 1.5 mm, and the radius of the outer chamfer 52 is 1.5 mm.

[0032] Preferably, the flange 6 is made of engineering polymer composite material. More specifically, the flange 6 includes a protrusion 62, a flange body 63 and an extension 64 connected in sequence. The protrusion 62, the flange body 63 and the extension 64 are integrally formed and can be directly formed by a mold. The connecting piece 2 is provided with a matching portion 24 corresponding to the protrusion 62. The diameter of the protrusion 62 is similar to the diameter of the matching portion 24. When the protrusion 62 is connected to the matching portion 24, the relative positioning and sealing of the flange 6 and the connecting piece 2 are completed. In addition, a plurality of connecting holes 631 are provided on the flange body 63. The connecting holes 631 can be connected to the above-mentioned fastener 7, and the number of the connecting holes 631 is preferably three. The connecting hole 631 can be a through hole or a threaded hole. Further, the distance of the extension 64 along the central axis direction of the flange body 63 is 16 mm, and the outer wall surface of the extension 64 can be tapered, which can play a role in extending and positioning the pipe body 1.

[0033] The fluid delivery pipeline also includes a quick plug 8 detachably connected to the pipe body 1, and the quick plug can facilitate the connection of other pipe bodies 1 or hoses.

[0034] The specific installation steps of the fluid delivery pipeline are:

[0035] 1. First install the multi-toothed retaining spring 3 into the position of the limiting step 22 of the connecting piece 2;

[0036] 2. Install the gasket 4 into the position of the multi-toothed circlip 3 to position and press the multi-toothed circlip 3;
