Technical Field

[0001] The utility model belongs to the technical field of water pipes and relates to a high-strength stainless steel water pipe, in particular to a high-strength stainless steel water pipe. Background Art

[0002] Stainless steel water pipes are pipes made of stainless steel and used to transport water and other liquids. Stainless steel water pipes are non-toxic, odorless, and easy to clean, meeting the hygiene requirements of the food, pharmaceutical and other industries. At the same time, stainless steel water pipes can be recycled and reused, and have good environmental performance.

[0003] There are ultra-thin-wall stainless steel water pipes on the current market, which have the advantages of beautiful appearance and light weight. However, due to the thinner wall thickness of ultra-thin-wall stainless steel water pipes, compared with thick-wall stainless steel water pipes, the compressive resistance of ultra-thin-wall stainless steel water pipes is relatively weak, and they are prone to deformation when under pressure, which may affect their service life. They are more susceptible to deformation due to external pressure during use and transportation, thereby affecting the use effect. Therefore, it is of great significance to design a high-strength stainless steel water pipe. Summary of the invention

DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figure 1 , 2 As shown in Figure 3, the high-strength stainless steel water pipe includes a pipe fitting 1, a protective sleeve 2 is arranged on the outside of the pipe fitting 1, a flange 3 is arranged on the connecting end of the pipe fitting 1, the protective sleeve 2 includes a thermal insulation layer 4 bonded to the outside of the pipe fitting 1, a reinforcement layer 5 is bonded to the outside of the thermal insulation layer 4, a buffer layer 6 is arranged on the outside of the reinforcement layer 5, and a pressure-resistant layer 7 is bonded to the outside of the buffer layer 6. The thermal insulation layer 4 is used to insulate the pipe fitting 1 and reduce the temperature loss when the pipe fitting 1 transports hot water. The reinforcement layer 5 is used to reinforce the pipe fitting 1 and increase the strength of the pipe fitting 1, so that the pipe fitting 1 is not easily impacted. The buffer layer 6 has good buffering and shock-absorbing effects. When the outside of the protective sleeve 2 is impacted, the impact is mitigated by the buffer layer 6. The pressure-resistant layer 7 has good bending and impact resistance, so that the surface of the protective sleeve 2 is not easily deformed, thereby maintaining the aesthetics of the water pipe.

[0017] Preferably, an installation groove 8 is opened on the inner wall of the flange 3, an installation frame 9 is arranged in the installation groove 8, and a filter screen 10 is arranged inside the installation frame 9. By installing the filter screen 10 at the water inlet port of the pipe fitting 1, impurities entering the pipe fitting 1 and causing corrosion to the inside of the pipe fitting 1 can be reduced.

[0018] Preferably, two symmetrical positioning blocks 11 are provided on the outside of the installation frame 9, a positioning groove 12 used in conjunction with the positioning block 11 is provided on the inner wall of the flange 3, a threaded hole 13 is provided on the positioning block 11, and a bolt 14 used in conjunction with the threaded hole 13 is provided on the flange 3. The installation frame 9 with the filter 10 is installed by the bolt 14, which facilitates the disassembly and replacement of the filter 10.

[0019] Preferably, the insulation layer 4 is made of mineral wool material, and the reinforcement layer 5 is made of polycarbonate material. Mineral wool has good thermal insulation and sound absorption properties, and has a good thermal insulation effect on the pipe 1. Polycarbonate has good impact resistance, so that the pipe 1 is not easily affected by impact.

[0020] Preferably, the compression-resistant layer 7 is made of polyamide material and the buffer layer 6 is made of rubber material. Polyamide is a material with high strength and good bending and impact resistance, which increases the strength of the pipe 1 and makes the appearance less likely to deform. Rubber has good buffering and shock-absorbing capabilities and can effectively mitigate impact.
