The pipeline system of the vulcanizer includes steam hot water, power water and various valves (function: to provide various vulcanization media or control to the vulcanizer through the pipeline). At present, the pipelines of the vulcanizers on the market are mostly made of EPDM rubber tubes (ethylene propylene diene monomer rubber), but EPDM rubber tubes are generally suitable for fluid systems with a conveying temperature not exceeding 120°C, and cannot withstand high temperatures of 200°C during tire vulcanization.

The energy-saving high-temperature tube 100 for tire vulcanization of the present application can improve the flexibility of the tube by setting the corrugated section 111 in the middle section of the inner tube 11, which is convenient for bending the tube, and can also balance the displacement and size change of the tube caused by climate and other reasons, or be used to eliminate the vibration of high-frequency machinery; and by wrapping the reinforcing layer 12 on the outer surface of the inner tube 11, the strength of the tube can be improved, the bending resistance and folding resistance can be improved, and the flowability inside the tube can be ensured; the outer surface of the reinforcing layer 12 is covered with an insulating layer 13, which can reduce heat loss and prevent burns. Aerogel felt is used as the insulating layer 13. Aerogel is the best thermal insulation material in the world. 80% of aerogel is air, which is the solid with the lowest density in the world. It can improve the thermal insulation effect and prevent heat loss, thereby achieving energy saving effect, and is conducive to lightweight.

[0033] In this embodiment, the inner tube 11 is a polytetrafluoroethylene tube. The polytetrafluoroethylene material has excellent dielectric properties and chemical corrosion resistance, high and low temperature resistance (-70℃~+260℃), waterproof, non-stick, good self-lubricating properties, etc., ensuring that the fluid in the tube moves smoothly at 207℃.

[0034] Optionally, the fiber braided layer is a polymer fiber braided layer or a metal wire braided layer. In the present embodiment, the fiber braided layer is a stainless steel wire braided layer. This can greatly enhance the protection of the polytetrafluoroethylene bellows, increase the overall strength and rigidity, bending and folding resistance, withstand the high pressure of 2.5Mpa generated during vulcanization, and improve corrosion resistance. Preferably, the fiber braided layer is a 304 stainless steel wire braided layer. In other embodiments, the fiber braided layer can also be woven from wires of high-strength polymer materials or other metal materials.

[0035] In this embodiment, the aerogel felt layer is a nano-silica aerogel felt. Nano-silica aerogel felt has good thermal insulation and heat preservation, and its maximum operating temperature is 650°C. The outer layer is wrapped with nano-silica aerogel felt, which can achieve thermal insulation and heat preservation, prevent heat loss, and achieve energy-saving effect; at the same time, the material is hydrophobic as a whole, and cannot be wetted by water when in contact with water in the air, so it protects the normal use of the composite pipe. In this embodiment, the aerogel felt layer is formed by winding strips of felt cloth. In other embodiments, the whole piece of felt cloth can be used to surround the cylindrical shape to form the thermal insulation layer 13. The cylindrical thermal insulation layer 13 can also be formed by integrally forming the whole piece of felt cloth, and the thickness of the thermal insulation layer 13 can also be determined according to the actual working conditions.

[0036] Preferably, a flange 113 is provided at one end of the straight pipe section 112 away from the corrugated section 111, and the flange 113 extends radially along the opening of the straight pipe section 112.

[0038] Specifically, Figure 1 As shown, the inner hole of the quick connector 21 is a stepped hole, wherein the inner hole diameter close to the corrugated section 111 is smaller than the inner hole diameter away from the corrugated section 111 , so the flange 113 abuts against the intersection of the stepped hole, which can prevent the quick connector 21 from separating from the inner tube 11 .

[0040] Furthermore, the connection assembly 20 further includes an outer sleeve 24, which is sleeved on the outer surface of the reinforcement layer 12 and the quick connector 21. The outer sleeve 24 can fill the diameter difference between the quick connector 21 and the reinforcement layer 12, prevent bending at the connection between the quick connector 21 and the straight pipe section 112, and also improve the appearance.

[0041] In one embodiment, the connection assembly 20 further includes a connection sleeve 25, which is sleeved on the straight pipe section 112 connected to the flange 22. The end of the connection sleeve 25 away from the quick connector 21 is provided with a folded edge 251 that abuts against the flange 113, and the flange 22 is sleeved on the surface of the connection sleeve 25.

[0043] The energy-saving high-temperature tube 100 for tire vulcanization of the present application has the advantages of resistance to high-pressure hot water, long service life, high cost performance, safety, energy saving and environmental protection. By setting the middle section of the inner tube 11 as a corrugated section 111, the flexibility of the pipeline can be improved, the pipeline can be easily bent, and the displacement and size change of the pipeline caused by climate and other reasons can be balanced or used to eliminate the vibration of high-frequency machinery; and by wrapping the reinforcement layer 12 on the outer surface of the inner tube 11, the strength of the pipeline can be improved, the bending resistance and folding resistance can be improved, and the flowability inside the pipeline can be ensured; the outer surface of the reinforcement layer 12 is covered with an insulation layer 13, which can reduce heat loss and prevent burns. Aerogel felt is used as the insulation layer 13. Aerogel is the best thermal insulation material in the world. 80% of aerogel is air, which is the solid with the lowest density in the world. It can improve the thermal insulation effect and prevent heat loss, thereby achieving energy saving effect, and at the same time is conducive to lightweight.
