Description

TECHNICAL FIELD

[0001] The utility model relates to the field of metal hose, concretely relates to a corrugated metal hose with flexible guide sleeve lining. BACKGROUND

[0002] At present, in order to improve the steel production efficiency, the blast furnace needs to maintain the flame in the furnace by high-pressure oxygen blowing, and the cooling water and oxygen blowing metal hose work in a high-temperature environment. However, the traditional metal hose will deform and age in a high-temperature and high-pressure environment, and its own thermal expansion coefficient is relatively large, which can easily cause installation and use difficulties. The metal hose lined with polytetrafluoroethylene is relatively light in volume and has excellent corrosion resistance, but the high-temperature resistance of polytetrafluoroethylene material is limited, and it is difficult to withstand the extremely high-temperature environment of 350 DEG C in the blast furnace.

[0003] The structural design of the conventional metal hose causes a relatively large resistance to the medium fluid, and when the oxygen is blown into the blast furnace, the medium fluid will generate a relatively large pressure loss. The 20-meter length of the hose seriously hinders the oxygen inlet pressure, which finally leads to insufficient pressure of the oxygen reaching the blast furnace, affecting the normal work of the blast furnace. SUMMARY

[0004] Therefore, the utility model aims at providing a corrugated metal hose with flexible guide sleeve lining to solve the problems of pressure loss and use difficulty in a high-temperature medium environment caused by the existing metal hose.

[0005] To achieve the above-mentioned purpose, the utility model provides a corrugated metal hose with flexible guide sleeve lining, which comprises a corrugated pipe and a winding pipe lining. The winding pipe lining is arranged in the corrugated pipe as lining, and the two ends of the winding pipe lining are fixed to the two ends of the corrugated pipe.

[0006] In one embodiment, the winding pipe lining further comprises a winding layer and a medium layer. The winding layer is tightly wound on the medium layer, and the medium layer directly contacts and transports the medium fluid.

[0007] In one embodiment, the material of the winding layer can be stainless steel metal material, and the winding mode of the winding layer can be spiral winding, circumferential winding or longitudinal winding.

[0008] In one embodiment, the corrugated metal hose further comprises two flanges, and the two flanges are respectively welded to the two ends of the corrugated pipe.

[0009] In one embodiment, the corrugated metal hose further comprises two pipe clamps, and the two pipe clamps are sleeved on the two ends of the corrugated pipe and abut against the two flanges.

[0010] In one embodiment, the corrugated metal hose further comprises a mesh sleeve, and the mesh sleeve is fixedly sleeved on the corrugated pipe.

[0011] In one embodiment, the number of mesh layers is two or more.

[0012] In one embodiment, the material of the bellows is metal and the inner wall is smooth.

[0013] In one embodiment, the material of the winding pipe lining is stainless steel.

[0014] Compared with the prior art, the utility model has beneficial effects. The corrugated metal hose realizes the functions of flexibility and pressure resistance and flexible rotation by arranging the flexible winding pipe lining in the bellows. The winding pipe lining comprises a winding layer and a medium layer, the winding layer tightly wraps the medium layer, and the medium layer directly contacts the conveying medium fluid, thereby ensuring the fluid sealing property and the overall integrity of the pipeline system. Meanwhile, the two ends of the bellows are welded with two flanges respectively, the flanges not only can enhance the connection strength, but also can better guarantee the connection sealing, avoid the leakage and loss phenomenon, and improve the safety of the whole system. The mesh cover of the corrugated metal hose is made of high-temperature-resistant material, and the thermal expansion coefficient is small, so that the problem of easy deformation or aging of the corrugated metal hose under high temperature can be effectively overcome; meanwhile, the winding pipe lining is made of stainless steel material, so that the flexibility of the corrugated metal hose is ensured, and the pressure loss of the medium fluid is effectively reduced.

[0020] The exemplary embodiments of the utility model will be described below with reference to the accompanying drawings.

[0021] Example 1, as Figure 1 As shown, a corrugated metal hose 100 with a flexible guide sleeve is provided. The corrugated metal hose 100 includes a corrugated pipe 10 and a spiral tube liner 20. The spiral tube liner 20 is disposed inside the corrugated pipe 10 as a liner, and the two ends of the spiral tube liner 20 are fixed to the two ends of the corrugated pipe 10.

[0022] Example 2, as Figure 1 As shown, based on Embodiment 1, the spiral tube liner 20 further includes a spiral layer 21 and a medium layer 22. The spiral layer 21 is tightly wound on the medium layer 22, and the medium layer 22 directly contacts and transports the medium fluid.

[0023] During use, the spiral wound layer 21 can be made of stainless steel, which has excellent flexibility and high strength. The winding method of the spiral wound layer 21 can be helical winding, circumferential winding, or longitudinal winding. The appropriate winding method and parameters are selected according to specific circumstances to ensure that the quality and performance of the spiral wound pipe lining 20 meet the requirements. This not only improves the corrosion and seepage prevention capabilities of the corrugated metal hose 100, but also enhances the strength and stability of the pipeline, adapting to the requirements of different working conditions and media, and providing strong protection for the long-term safe operation of the pipeline system.

The multi-layer mesh sleeve 50 is interwoven with each other to form a stable support structure, ensuring the stable operation of the corrugated metal hose 100 in various complex environments. The mesh sleeve 50 is tightly fitted on the corrugated pipe 10, and provides additional support and protection for the corrugated pipe 10 through its unique weaving or winding method. This fixing method not only enhances the stability of the corrugated metal hose 100, but also reduces the risk of damage caused by pipe vibration or external impact. The mesh sleeve 50 can also be made of corrosion-resistant and wear-resistant materials, which have excellent mechanical properties and can effectively resist the erosion of abrasive environments.

[0027] By selecting metal materials with smooth inner walls to make the corrugated pipe 10 and the winding pipe lining 20, the flexibility of the corrugated metal hose 100 is ensured, which can easily adapt to various complex installation environments and stress conditions, and can also effectively alleviate and significantly reduce the problem of pressure loss commonly encountered by traditional metal hoses during use. Moreover, the corrugated metal hose 100 can also be applied in high-temperature medium environments, greatly expanding the application field of the corrugated metal hose 100, enabling it to work safely and reliably in more high-temperature working conditions.

[0028] During use, the corrugated metal hose 100 can be used for cooling water metal hoses for converter in steel mills, oxygen blowing metal corrugated pipes, etc., solving the problem of pressure loss of cooling water metal hoses and oxygen blowing metal hoses for blast furnaces due to high-temperature environments and long-distance transmission, meeting the normal working requirements of blast furnaces, and at the same time, the winding pipe lining 20 material is made of stainless steel material, which is resistant to high temperature and has long service life, can work stably for a long time, and significantly improves the production efficiency and safety of the blast furnace.
