Abstract
Description
Technical Field
[0001] This application relates to the field of upstream piping, and more particularly to an insulating and flame-retardant heating jacket for upstream piping. Background Technology
[0002] Currently, to prevent the gas in the pre-tube from crystallizing at low temperatures and sticking to the pipe, causing blockage, the pipe is heated to prevent gas from crystallizing, thus reducing the frequency of pipe cleaning. Ohm's law and Joule's law are used to energize the resistance wire to generate heat, which is then transferred to the pipe to keep it within a certain range.
[0003] However, existing heating jackets usually do not have bending capabilities. When using pipelines, the pipelines often make bends, which makes it difficult for the heating jackets to adapt well. This requires the development of corresponding heating jackets, which reduces the adaptability of the heating jackets. At the same time, existing heating jackets usually do not have insulation and flame retardant effects. Utility Model Content

A first connector and a second connector are fixed to both ends of the heating wire, respectively.
[0006] By adopting the above technical solution, multiple heating wires inside the jacket body are connected in series through the first connector and the second connector. When one or more heating wires fail, the entire circuit will be de-energized and cooled down.
[0007] Preferably, the support rod is U-shaped, and a turntable is rotatably connected to one end of the support rod near the first clamping body. The bottom of the turntable is fixed to the top of one end of the first clamping body.
[0008] By adopting the above technical solution, the first and second jacket bodies are connected by a support rod, and the turntable rotates on the top of the first jacket body, so that the included angle between the first and second jacket bodies can be changed.
[0009] Preferably, the central axis of the connecting shaft is on the same straight line as the central axis of the bellows, and the height of the connecting shaft is less than the sum of the thicknesses of the first connecting rod and the second connecting rod.
[0010] By adopting the above technical solution, the fastening bolt is rotated to make the fastening bolt fit into the second connecting rod, the second connecting rod fit into the first connecting rod, and the first connecting rod fit into the support rod, and the mutual friction force is used to limit the movement.
[0011] Preferably, the placement groove is spirally arranged, and the heating wire is attached and fixed to the side of the placement groove near the inner wall of the first jacket.
[0012] By adopting the above technical solution, the heating wire is spirally fixed to one side of the inner wall of the first jacket and the second jacket, so that the heating wire can effectively heat the first jacket and the second jacket.

[0014] By adopting the above technical solution, multiple heating wires inside the jacket body are connected in series through the first connector and the second connector, so that multiple heating wires can form a complete circuit.
[0015] Preferably, the first jacket and the second jacket are provided with an inner coating on one side of the outer wall and one side of the inner wall, and the inner coating is made of silicone double-sided coated glass fiber cloth.
[0016] By adopting the above technical solution, the first and second jackets have excellent resistance to atmospheric aging and non-flammability, and the other materials inside also have high temperature resistance, thus enabling the first and second jackets to have insulation and flame retardant effects.
[0017] Preferably, the corrugated pipe is arranged in a double layer, and an air layer is provided in the middle of the corrugated pipe.

[0020] 1. This application adjusts the angle of the first jacket and the second jacket at the bend of the pipe. The turntable rotates on the top of the first jacket, so that the included angle between the first jacket and the second jacket can be changed. After the angle is adjusted, the fastening bolt is rotated so that the fastening bolt is in contact with the second connecting rod, the second connecting rod is in contact with the first connecting rod, and the first connecting rod is in contact with the support rod. The friction between them limits the movement, thereby achieving the effect of quickly adjusting the included angle between two adjacent heating jackets.
[0021] 2. The first and second jacket bodies of this application are provided with an inner coating on one side of the outer wall and one side of the inner wall. The inner coating is made of silicone double-coated fiberglass cloth, which makes the first and second jacket bodies have excellent resistance to atmospheric aging and non-flammability, thereby enabling the first and second jacket bodies to have insulation and flame retardant effects.

A second connecting block 8 is fixed to the top of the second jacket body 2. The second connecting block 8 and the second connecting rod 9 are fixed together. The first connecting block 6 and the first connecting rod 7 are fixed together. The connecting shaft 16 is internally threaded with a fastening bolt 10. The first connecting rod 7 and the second connecting rod 9 connect the first jacket body 1 and the second jacket body 2, so that the angle between the first jacket body 1 and the second jacket body 2 can be changed. The first jacket body 1 and the second jacket body 2 are both provided with placement grooves 12. The placement grooves 12 are fixed with heating wires 13. The two ends of the heating wires 13 are respectively fixed with a first connector 14 and a second connector 15. The heating wires 13 inside the multiple jacket bodies are connected in series through the first connector 14 and the second connector 15. When one or more heating wires 13 fail, the entire circuit will be de-energized and cooled down.
[0029] Reference Appendix Figure 1 The support rod 4 is U-shaped. A turntable 5 is rotatably connected to one end of the support rod 4 near the first jacket body 1. The bottom of the turntable 5 is fixed to the top of one end of the first jacket body 1. The first jacket body 1 and the second jacket body 2 are connected by the support rod 4. The turntable 5 rotates on the top of the first jacket body 1, so that the included angle between the first jacket body 1 and the second jacket body 2 can be changed.
[0030] Reference Appendix Figure 3 The central axis of the connecting shaft 16 is on the same straight line as the central axis of the bellows 3. The height of the connecting shaft 16 is less than the sum of the thicknesses of the first connecting rod 7 and the second connecting rod 9. After the angle is adjusted, the fastening bolt 10 is rotated to make the fastening bolt 10 fit with the second connecting rod 9, the second connecting rod 9 fit with the first connecting rod 7, and the first connecting rod 7 fit with the support rod 4. The mutual friction force limits the movement.
[0031] Reference Appendix Figure 2 The placement groove 12 is spirally arranged, and the heating wire 13 is attached and fixed to the side of the placement groove 12 near the inner wall of the first jacket body 1. The heating wire 13 is spirally fixed to the inner wall of the first jacket body 1 and the second jacket body 2, so that the heating wire 13 can heat the first jacket body 1 and the second jacket body 2 well.

The first jacket body 1 and the second jacket body 2 are connected by the corrugated pipe 3, so that they are not affected when they are bent. At the same time, the hollow layer in the middle can provide good heat preservation.
[0035] The implementation principle of an insulating and flame-retardant heating jacket for a pre-pipeline according to an embodiment of this application is as follows: First, multiple sets of first jacket bodies 1 and second jacket bodies 2 are sequentially fitted onto the outside of the pre-pipeline. Then, the multiple sets of first jacket bodies 1 and second jacket bodies 2 are connected. Subsequently, the angles of the first jacket bodies 1 and second jacket bodies 2 are adjusted at the bends in the pipeline. The first jacket bodies 1 and second jacket bodies 2 are connected by a support rod 4. A turntable 5 rotates on the top of the first jacket body 1, allowing the included angle between the first jacket body 1 and the second jacket body 2 to be changed. After the angle adjustment is completed, the fastening bolt 10 is rotated to tighten the bolt. The bolt 10 is attached to the second connecting rod 9, the second connecting rod 9 is attached to the first connecting rod 7, and the first connecting rod 7 is attached to the support rod 4. The mutual friction force limits the movement. After installation, the heating wires 13 inside the multiple jacket bodies are connected in series through the first connector 14 and the second connector 15, so that the multiple heating wires 13 can form a complete circuit. The heating wires 13 are spirally fixed to one side of the inner wall of the first jacket body 1 and the second jacket body 2, so that the heating wires 13 can effectively heat the first jacket body 1 and the second jacket body 2, and can heat the upstream pipeline to prevent low-temperature crystallization.
