Description

Technical Field

[0001] This utility model relates to the field of stainless steel water pipe technology, specifically to a corrosion-resistant stainless steel water pipe. Background Technology

[0002] Stainless steel water pipes are the best material for directly transporting drinking water. They have a very low leakage rate, which can save precious water resources. In the event of an earthquake, the water supply system may be damaged, but the stainless steel water pipe system will remain intact. In addition, compared with copper water pipes, stainless steel water pipes have better water permeability. The high strength of stainless steel water pipes greatly reduces the possibility of leakage due to external forces, significantly reducing the water leakage rate and enabling water resources to be effectively protected and utilized.

[0003] When using existing stainless steel water pipes, elbows are needed to connect the pipes at bends. When water flows, especially at bends, the impact is greater, and prolonged use can easily cause impact damage to the bends, affecting the service life of the water pipes. Therefore, a corrosion-resistant stainless steel water pipe has been proposed. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a corrosion-resistant stainless steel water pipe to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant stainless steel water pipe, comprising a pipe body, wherein the pipe body is a bent pipe, and a spring and a fixing rod are fixedly connected to the inner wall of the pipe body at the bend, wherein the spring and the fixing rod are inclined, and a buffer plate is fixedly connected to the other end of the spring, wherein a movable rod is movably inserted into the inner surface of the fixing rod, and the other end of the movable rod is fixedly connected to the buffer plate.

[0006] Furthermore, the tube body includes a base layer and two anti-corrosion layers, which are respectively disposed on both sides of the base layer. The base layer is made of stainless steel, and the anti-corrosion layers include a stainless steel layer, a graphene fiber layer, and a zirconium-titanium alloy coating. The zirconium-titanium alloy is coated on the surface of the graphene fiber layer.

[0007] Furthermore, the stainless steel layer is disposed on the side of the zirconium-titanium alloy coating away from the substrate layer, and the graphene fiber layer is disposed on the side of the zirconium-titanium alloy coating close to the substrate layer.

[0008] Furthermore, the tube body is covered with a protective sleeve, which is made of glass wool, and a PE outer film is provided on the outside of the glass wool.

[0009] Furthermore, the graphene fiber layer is connected to the stainless steel layer by PP adhesive.

[0010] Furthermore, the outer surface of the buffer plate has several through holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this corrosion-resistant stainless steel water pipe, the impact force of the water flow is transmitted to the buffer plate, causing the movable rod to move inside the fixed rod, which deforms the spring. The spring buffers the impact force on the buffer plate, preventing the water flow from directly impacting the bend of the stainless steel water pipe, thus protecting the bend and increasing the service life of the stainless steel water pipe bend.

[0013] 2. This corrosion-resistant stainless steel water pipe features a three-layer anti-corrosion coating consisting of a stainless steel layer, a graphene fiber layer, and a zirconium-titanium alloy coating. This enhances the overall corrosion resistance of the pipe, extends its service life, and provides external protection by a protective sleeve to prevent corrosion caused by prolonged exposure to wind and sun when installed outdoors.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please refer to the following: Figures 1-5 This utility model provides a technical solution: a corrosion-resistant stainless steel water pipe, including a pipe body 1, which is a bend. A spring 2 and a fixing rod 4 are fixedly connected to the inner wall of the pipe body 1 at the bend. The spring 2 and the fixing rod 4 are inclined. A buffer plate 3 is fixedly connected to the other end of the spring 2. A movable rod 5 is movably inserted into the inner surface of the fixing rod 4. The other end of the movable rod 5 is fixedly connected to the buffer plate 3. Specifically, when the bend is impacted by water flow, the water flow contacts the buffer plate 3, and the buffer plate 3 is subjected to force, causing the movable rod 5 to move inside the fixing rod 4 and causing the spring 2 to deform. The spring 2 buffers the force on the buffer plate 3, preventing the water flow from directly impacting the bend of the stainless steel water pipe, thus protecting the bend and increasing the service life of the stainless steel water pipe bend.

[0023] In this embodiment, the pipe body 1 includes a base layer 8 and two anti-corrosion layers 9. The two anti-corrosion layers 9 are respectively disposed on both sides of the base layer 8. The base layer 8 is made of stainless steel. The anti-corrosion layers 9 include a stainless steel layer 10, a graphene fiber layer 11, and a zirconium-titanium alloy coating 12. The zirconium-titanium alloy is coated on the surface of the graphene fiber layer 11. Specifically, the pipe body 1 is protected against corrosion by three layers of stainless steel layer 10, graphene fiber layer 11, and zirconium-titanium alloy coating 12, which improves the overall corrosion resistance of the water pipe and extends its service life.

[0024] In this embodiment, the stainless steel layer 10 is disposed on the side of the zirconium-titanium alloy coating 12 away from the substrate layer 8, and the graphene fiber layer 11 is disposed on the side of the zirconium-titanium alloy coating 12 close to the substrate layer 8. Specifically, by adopting the above technical solution, the stainless steel layer 10 is positioned facing outward and inward toward the substrate layer 8.

[0025] In this embodiment, a protective sleeve 7 is provided on the outside of the pipe body 1. The protective sleeve 7 is made of glass wool, and a PE outer film is provided on the outside of the glass wool. Specifically, by providing glass wool, the influence of the external environment on the water flow in the water pipe can be reduced, and by providing a PE outer film, the outside of the protective sleeve 7 has a certain degree of wear resistance.

[0026] In this embodiment, the graphene fiber layer 11 is connected to the stainless steel layer 10 by PP adhesive. Specifically, the PP adhesive has high bonding strength, high transparency after curing, does not harden, and has good waterproof performance.

[0027] In this embodiment, the outer surface of the buffer plate 3 is provided with several through holes 6. Specifically, the through holes 6 are provided to divert and buffer the water flow when it impacts the buffer plate 3.

[0028] Working principle: When this utility model is in use, when the bend is impacted by water flow, the water flow comes into contact with the buffer plate 3, the buffer plate 3 is subjected to force, causing the movable rod 5 to move inside the fixed rod 4, and causing the spring 2 to deform. The spring 2 buffers the force on the buffer plate 3, preventing the water flow from directly impacting the bend of the stainless steel water pipe, protecting the bend and increasing the service life of the stainless steel water pipe bend.

[0029] The pipe body 1 is protected against corrosion by a three-layer anti-corrosion system consisting of a stainless steel layer 10, a graphene fiber layer 11, and a zirconium-titanium alloy coating 12. This improves the overall anti-corrosion capability of the water pipe and extends its service life. The protective sleeve 7 protects the exterior of the pipe body 1, preventing corrosion caused by prolonged exposure to wind and sun when the water pipe is installed outdoors.
