Description

Technical Field

[0001] This utility model relates to the field of flexible joint technology, and in particular to a flexible joint for epoxy fiberglass pipelines. Background Technology

[0002] Epoxy fiberglass reinforced plastic (GFRP) flexible pipe joints are commonly used in liquid and gas pipelines to connect two pipe sections. They are frequently used in pipeline systems in the oil, natural gas, chemical, water supply, and drainage industries, exhibiting excellent corrosion resistance, mechanical strength, and chemical stability. With industrial development, the demands on pipe fittings are increasing, requiring not only strong mechanical and corrosion resistance but also good flexibility to accommodate changes in the pipeline system such as thermal expansion, contraction, vibration, and displacement.

[0003] Most existing pipe connection methods rely on traditional metal joints or rubber joints, but these joints are prone to corrosion, aging, and wear during long-term use, which leads to a decrease in the connection strength and sealing of the pipes, affecting the safety and stability of the pipeline system.

The reinforcing component is used to enhance the strength of the connecting sleeve.

[0010] As a further description of the above technical solution:

[0011] The reinforcement component includes a reinforcement layer, which is fixedly connected to the outside of the anti-aging layer.

[0012] As a further description of the above technical solution:

A second fixing ring 13 is fixedly connected to the right side of the connecting ring 3, and a second pipe 14 is fixedly connected to the right side of the second fixing ring 13.

[0032] By manually moving the first pipe 1, the first fixing ring 2 is moved. The movement of the first fixing ring 2 causes the insertion ring 3 to be inserted into the insertion slot 8. At the same time, the movement of the insertion ring 3 causes the insertion block 4 to be inserted into the connection slot 10. By rotating the first pipe 1 and the first connecting ring 9 in reverse, the two insertion blocks 4 are slid into the connection slot 10. The spring 7 generates elastic force to cause the locking plate 6 to be locked into the through slot 11. Then, by manually moving the second pipe 14, the above operation is repeated, which can facilitate a tight connection between the two pipes.

[0033] Reference Figure 1 , Figure 2 , Figure 5 An epoxy resin layer 15 is fixedly connected inside the connecting sleeve 12, an anti-aging layer 16 is fixedly connected outside the epoxy resin layer 15, and a reinforcing component is fixedly connected outside the anti-aging layer 16. The reinforcing component is used to enhance the strength of the connecting sleeve 12. The reinforcing component includes a reinforcing layer 17, which is fixedly connected to the outside of the anti-aging layer 16.

[0034] The epoxy resin layer 15 has excellent adhesion, mechanical properties and corrosion resistance, the anti-aging layer 16 has excellent UV resistance, and the reinforcing layer 17 has high tensile strength, compressive strength and flexural strength, which effectively improves the strength, wear resistance and anti-aging ability of the connecting sleeve 12.

[0036] The plug-in block 4 is slidably connected inside the connecting groove 10, and the retaining plate 6 is slidably connected inside the through groove 11, which facilitates the connection of the two pipes. The first fixing ring 2 is rotatably connected to the left side of the connecting ring 9, and the second fixing ring 13 is rotatably connected to the right side of the connecting ring 9, which provides support and limit the two pipes. The first rubber sealing ring 18 and the second rubber sealing ring 19 are fixedly connected to the outside of the plug-in ring 3, which effectively improves the sealing performance of the joint. The anti-aging layer 16 and the reinforcing layer 17 are both fixedly connected to the inside of the connecting sleeve 12, which effectively improves the strength, wear resistance and anti-aging ability of the connecting sleeve 12.

[0037] Working principle: When using this device, manually moving the first pipe 1 moves the first fixing ring 2, which in turn moves the insertion ring 3, inserting the insertion ring 3 into the insertion slot 8. Simultaneously, the insertion ring 3 moves the insertion block 4 into the connecting slot 10. Reversing the rotation of the first pipe 1 and the first connecting ring 9 causes the two insertion blocks 4 to slide into the connecting slot 10. The spring 7 generates elastic force, moving the locking plate 6 and locking it into the through slot 11. Then, manually moving the second pipe 14 repeats the above operation, allowing for convenient tightening of the two pipes. The connection is tight, the operation is relatively simple, and the practicality is high. The epoxy resin layer 15 has excellent adhesion, mechanical properties and corrosion resistance. The anti-aging layer 16 has excellent UV resistance and can be exposed to the outdoor environment for a long time without aging, embrittlement or fading. It is suitable for long-term use in harsh environments. The reinforcing layer 17 has high tensile strength, compressive strength and bending strength, and can withstand greater mechanical stress, reducing damage caused by external forces. It can effectively improve the strength, wear resistance and anti-aging ability of the connecting sleeve 12, thereby improving its service life.
