Description

Technical Field

[0001] The invention relates to the technical field of polyethylene water supply pipes, in particular to a rare earth antibacterial PE water supply pipe. Background Art

[0002] PE water supply pipes are made of polyethylene and other materials. Due to their high strength, corrosion resistance, and non-toxicity, they are widely used in the field of water supply pipe manufacturing. Because PE water supply pipes do not rust, they have good applicability and are often used in chemical, construction and other fields. However, the existing PE water supply pipes have some shortcomings, such as:

[0003] Application number: CN202210725998.6 An antibacterial and crack-resistant PE water supply pipe and a preparation method thereof. The PE water supply pipe can utilize the expansion and contraction of the PE corrugated belt to expand the internal space of the water supply inner pipe, thereby preventing the water supply inner pipe from being subjected to excessive expansion pressure and causing the water supply inner pipe to rupture. However, in actual use, the PE water supply pipe is difficult to support the interior of the water supply pipe, which may cause the water pipe to be deformed by external pressure or strong internal water pressure, thereby reducing the durability of the equipment.

[0004] Therefore, we proposed a rare earth antibacterial PE water supply pipe to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a rare earth antibacterial PE water supply pipe to solve the problem raised in the above background technology that most PE water supply pipes on the market are difficult to support the inside of the water supply pipe, which may cause the water pipe to be deformed by external pressure or strong internal water pressure, thereby reducing the durability of the equipment.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a rare earth antibacterial PE water supply pipe, comprising a pipe body and a fixing seat provided below the pipe body; the bottom of the pipe body is fixedly connected to the fixing seat, and a connecting mechanism is provided at the right end of the pipe body, and the pipe body is connected to another set of pipe bodies through the connecting mechanism;

[0007] The right end of the pipe body is connected with a fixing sleeve, and the fixing sleeve fixes the pipe body, and the right end of the fixing sleeve is fixedly connected to the fixing seat, and the right end of the fixing seat is fixedly connected to the connecting mechanism.

[0008] The bottom side of the pipe body can be fixed by the fixing seat at the bottom of the pipe body, and the top of the pipe body can be buffered by the fixing seat when it is subjected to pressure. At the same time, since the pipe bodies are interconnected through a connecting mechanism, the connection between the two groups of pipes can be protected by the connecting mechanism, so that when the pipe body itself is subjected to pressure, it can be buffered by the pipe body itself and the fixing seat, and when the connection is subjected to pressure, it can be protected by the connecting mechanism.

[0009] As a preferred technical solution of the present invention, the pipeline body includes an antibacterial tube layer, and a fixed tube is connected to the outside of the antibacterial tube layer, and a support damper is connected to the outside of the fixed tube, and a support pipe sheet is connected to the outside of the support damper, and a bonding pipe sheet is connected to the outside of the support pipe sheet, and a buffer layer is provided between the bonding pipe sheet and the fixed tube;

[0010] The outside of the fitted tube sheet is connected to an anti-aging tube layer, and the left end of the anti-aging tube layer is fixedly connected to the fixed sleeve, and the antibacterial tube layer, the fixed tube and the left end of the fitted tube sheet are all fixedly connected to the fixed sleeve.

[0011] The adoption of the above technical solution ensures that after the gas and liquid enter the pipeline body, the bacteria in the gas and liquid will not be adsorbed inside the pipeline body and damage the pipeline, thereby increasing the durability of the equipment. Moreover, through the setting of the support damping and the support pipe sheet, when the outside or inside of the pipeline body is under pressure, the pressure can be transmitted to the support damping, and the pressure is transmitted to the support pipe sheet and the buffer layer through the support damping for pressure buffering, thereby increasing the antibacterial performance of the inner wall of the pipeline body and the pressure resistance of the middle layer of the pipeline.

[0012] As a preferred technical solution of the present invention, the bottom of the anti-aging tube layer is fitted with the fixed seat, and the fixed seat includes a fitting seat, and the left end of the fitting seat is connected to a fixed bottom cover, the top of the fixed bottom cover is connected to a fixing ring, and the fixing ring is fixedly connected to the fixing sleeve, and a first connecting bolt is provided at the bottom of the fixed bottom cover.

[0013] The above technical solution can make the fixing seat more stable when supporting and protecting the bottom of the pipe body, so that the pipe body can be more firmly installed or fixed when it is installed again, thereby increasing the strength of the water supply pipe.

[0014] As a preferred technical solution of the present invention, the right end of the fitting seat is fixedly connected to the connecting mechanism, and the connecting mechanism includes a first flange, and a first sealing ring is provided at the right end of the first flange, a second sealing ring is provided at the bottom of the first sealing ring, and a second connecting bolt is provided on the outside of the first sealing ring, and the first sealing ring is fixedly connected to the second sealing ring through the second connecting bolt;

[0015] A second flange is provided at the right end of the first sealing ring and the second sealing ring, and thread grooves are provided inside the first flange and the second flange, and fixing bolts are provided inside the thread grooves. The first flange is fixedly connected to the second flange by the fixing bolts.

[0016] The above technical solution can make the connection between the two groups of pipe bodies more stable, and through the setting of the first sealing ring and the second sealing ring, when the antibacterial tube layers inside the two groups of pipe bodies are docked, the first sealing ring and the second sealing ring can be used to seal the outer side of the antibacterial tube layer, thereby increasing the sealing performance of the pipe bodies when docking.

[0017] As a preferred technical solution of the present invention, a bonding film is provided inside the first flange and the second flange, and the outer side of the antibacterial tube layer inside the pipeline body is fixedly connected to the first flange and the second flange through the bonding film.

[0018] The above technical solution enables the antibacterial tube layer to be connected to the antibacterial tube layer through the bonding film when it is bonded to the first flange and the second flange, thereby making the first flange and the second flange more firmly connected to the antibacterial tube layer and increasing the sealing performance of the antibacterial tube layer when connected to the connecting mechanism.

[0019] As a preferred technical solution of the present invention, the buffer layer inside the pipe body is made of rubber particles, and the buffer layer is located outside the support damper, and the buffer layer is elastic.

[0020] The above technical solution enables the middle layer of the pipeline body to buffer the pressure through the rubber particles inside the buffer layer when the middle layer of the pipeline body is subjected to pressure, thereby increasing the pressure resistance of the pipeline body.

[0021] As a preferred technical solution of the present invention, the left end of the buffer layer inside the pipe body is fitted with the fixed sleeve, and a connecting sealing sleeve is provided at the left end of the fixed sleeve, and the fixed sleeve is fixedly connected to the connecting sealing sleeve, and an anti-UV coating film is provided on the outside of the anti-aging pipe layer.

[0022] The above technical solution enables the anti-aging pipe layer to absorb and protect strong ultraviolet rays through the anti-UV coating film when providing anti-aging protection for the erosion of the outside of the pipeline body, thereby avoiding the occurrence of high-intensity ultraviolet rays in the anti-aging pipe layer causing cracks, thereby increasing the protection and anti-ultraviolet strength of the pipeline body itself.

[0023] As a preferred technical solution of the present invention, another pipeline connection method is provided at the right end of the pipeline body, and a sealing shell is provided at the right end of the pipeline body, and protective sleeves are provided at both ends of the left end of the sealing shell. The inside of the protective sleeve is fitted with the anti-aging pipe layer inside the pipeline body, and a group of cylindrical shells are provided on both sides of the front end of the protective sleeve, and a threaded shaft is provided inside the cylindrical shell, a threaded sleeve is provided on the outside of the threaded shaft, and a connecting spring shaft is connected to the inside of the threaded sleeve, and a sealing tube is connected to the inside of the connecting spring shaft, and the two groups of sealing tubes are fitted and connected to each other.

[0024] The above technical solution can be used to more conveniently fix pipe bodies of different sizes, and by setting the sealing shell, the joints between the two sets of pipe bodies can be protected, thereby increasing the sealing and protection of the equipment when docking pipes.

[0025] As a preferred technical solution of the present invention, a torsion shaft is fixedly connected to the outside of the threaded shaft, and the torsion shaft is located outside the cylindrical shell, and the cylindrical shell is rotationally connected to the torsion shaft.

[0026] The adoption of the above technical solution can make it more convenient for the user to rotate the threaded shaft, and can enable the cylindrical shell to limit the threaded shaft by twisting the shaft, thereby increasing the adjustability of the device during use.

[0027] Compared with the prior art, the present invention has the following advantages: the bottom side of the pipe body can be fixed by the fixing seat at the bottom of the pipe body, and when the top of the pipe body is subjected to pressure, the pipe body can be buffered by the fixing seat. At the same time, since the pipe bodies are interconnected by a connecting mechanism, the connection between the two groups of pipes can be protected by the connecting mechanism, so that when the pipe body itself is subjected to pressure, it can be buffered by the pipe body itself and the fixing seat, and when the connection is subjected to pressure, it can be protected by the connecting mechanism.

[0028] Furthermore, by providing an antibacterial pipe layer inside the pipe body, bacteria in the gas and liquid will not be adsorbed inside the pipe body and damage the pipe after entering the pipe body, thereby increasing the durability of the equipment. Moreover, by providing the support damper and the support pipe sheet, when the outside or inside of the pipe body is under pressure, the pressure can be transmitted to the support damper. The pressure is then transmitted to the support pipe sheet and the buffer layer through the support damper for pressure buffering, thereby increasing the antibacterial performance of the inner wall of the pipe body and the pressure resistance of the pipe middle layer.

[0029] Furthermore, by arranging an anti-UV coating film on the outside of the anti-aging pipe layer, the anti-aging pipe layer can absorb and protect strong ultraviolet rays while performing anti-aging protection against erosion on the outside of the pipeline body, thereby avoiding the occurrence of high-intensity ultraviolet rays in the anti-aging pipe layer causing sun cracking, thereby increasing the protection and anti-UV strength of the pipeline body itself.

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] Example 1: In order to solve the problem that the water supply pipe in the prior art is difficult to withstand high pressure, the following solution is disclosed. Please refer to Figure 1-Figure 7 The present invention provides a technical solution: a rare earth antibacterial PE water supply pipe, comprising a pipe body 1 and a fixing seat 2 provided below the pipe body 1; the bottom of the pipe body 1 is fixedly connected to the fixing seat 2, and a connecting mechanism 3 is provided at the right end of the pipe body 1, and the pipe body 1 is connected to another set of pipe bodies 1 through the connecting mechanism 3;

[0044] The pipeline body 1 includes an antibacterial tube layer 4, and a fixed tube 5 is connected to the outside of the antibacterial tube layer 4, and a support damper 6 is connected to the outside of the fixed tube 5. The support damper 6 is connected to the outside of a support pipe sheet 7, and the support pipe sheet 7 is connected to the outside of a bonding pipe sheet 8, and a buffer layer 9 is provided between the bonding pipe sheet 8 and the fixed tube 5.

[0045] The outside of the fitting tube sheet 8 is connected to an anti-aging tube layer 10, and the left end of the anti-aging tube layer 10 is fixedly connected to the fixed sleeve 11, and the antibacterial tube layer 4, the fixed tube 5 and the left end of the fitting tube sheet 8 are all fixedly connected to the fixed sleeve 11;

[0046] When water or gas passes through the pipe body 1 again, the inner wall of the antibacterial tube layer 4 will adhere to the water or gas, so that bacteria inside the water or gas will not adhere to the inner wall of the antibacterial tube layer 4 and corrode the pipe body 1. When the pipe body 1 itself is subjected to external pressure, the support damper 6 will drive the support pipe sheet 7 to shrink inward, so that the buffer layer 9 supports the support pipe sheet 7 and the bonding pipe sheet 8, so that the bonding pipe sheet 8 cooperates with the buffer layer 9 to buffer the pressure, thereby reducing the pressure on the antibacterial tube layer 4 and the fixed tube 5, thereby preventing the pipe body 1 from being deformed and ruptured, and increasing the pressure resistance of the pipe body 1 itself.

[0047] The bottom of the anti-aging tube layer 10 is fitted with the fixing seat 2, and the fixing seat 2 includes a fitting seat 13, and the left end of the fitting seat 13 is connected to a fixed bottom cover 14, the top of the fixed bottom cover 14 is connected to a fixing ring 15, and the fixing ring 15 is fixedly connected to the fixing sleeve 11, and a first connecting bolt 16 is provided at the bottom of the fixed bottom cover 14;

[0048] The right end of the fitting seat 13 is fixedly connected to the connecting mechanism 3, and the connecting mechanism 3 includes a first flange 17, and a first sealing ring 18 is provided at the right end of the first flange 17. A second sealing ring 19 is provided at the bottom of the first sealing ring 18, and a second connecting bolt 20 is provided on the outside of the first sealing ring 18. The first sealing ring 18 is fixedly connected to the second sealing ring 19 through the second connecting bolt 20;

[0049] A second flange 21 is provided at the right end of the first sealing ring 18 and the second sealing ring 19, and a thread groove 23 is provided inside the first flange 17 and the second flange 21, and a fixing bolt 22 is provided inside the thread groove 23. The first flange 17 is fixedly connected to the second flange 21 by the fixing bolt 22;

[0050] The first flange 17 and the second flange 21 are both provided with a bonding film 24, and the outer side of the antibacterial tube layer 4 inside the pipe body 1 is fixedly connected to the first flange 17 and the second flange 21 through the bonding film 24; the buffer layer 9 inside the pipe body 1 is made of rubber particles and is located outside the support damper 6. The buffer layer 9 is elastic.

[0051] The left end of the buffer layer 9 inside the pipe body 1 is in contact with the fixing sleeve 11, and the left end of the fixing sleeve 11 is provided with a connecting sealing sleeve 12, and the fixing sleeve 11 and the connecting sealing sleeve 12 are fixedly connected. The outer side of the anti-aging pipe layer 10 is provided with an anti-ultraviolet coating film;

[0052] When the two groups of pipe bodies 1 are connected to each other, the antibacterial tube layer 4 at the right end extension of the pipe body 1 is connected to the inside of the connecting mechanism 3, so that the antibacterial tube layer 4 extending inside the two groups of pipe bodies 1 passes through the first flange 17 and the second flange 21 and fits together, and then the first sealing ring 18 and the second sealing ring 19 are fit together, and at the same time, the first sealing ring 18 and the second sealing ring 19 are connected by the second connecting bolt 20, so that the first sealing ring 18 and the second sealing ring 19 seal and fix the fitting part of the antibacterial tube layer 4 extending from the two groups of pipe bodies 1, and then the first flange 17 and the second flange 21 are fixed by the fixing bolts 22, so that the first flange 17 and the second flange 21 can be fit and fixedly connected with the first sealing ring 18 and the second sealing ring 19.

[0053] Example 2: Please refer to Figures 8-10 The difference between this embodiment and embodiment 1 is that: another pipe connection method is provided at the right end of the pipe body 1, and a sealing shell 25 is provided at the right end of the pipe body 1, and protective sleeves 26 are provided at both ends of the left end of the sealing shell 25. The interior of the protective sleeve 26 is in contact with the anti-aging pipe layer 10 inside the pipe body 1, and a group of cylindrical shells 27 are provided on both sides of the front end of the protective sleeve 26, and a threaded shaft 29 is provided inside the cylindrical shell 27. A threaded sleeve 30 is provided on the outside of the threaded shaft 29, and a connecting spring shaft 31 is connected to the inside of the threaded sleeve 30, and a sealing tube 32 is connected to the inside of the connecting spring shaft 31, and the two groups of sealing tubes 32 are in contact with each other.

[0054] The outer side of the threaded shaft 29 is fixedly connected to a torsion shaft 28, and the torsion shaft 28 is located outside the cylindrical shell 27, and the cylindrical shell 27 is rotatably connected to the torsion shaft 28;

[0055] When the two groups of pipe bodies 1 are connected, the antibacterial tube layers 4 extending from the two groups of pipe bodies 1 are fitted inside the sealing shell 25, and the protective sleeve 26 is also fitted with the antibacterial tube layer 4. Then the torsion shaft 28 is rotated so that the torsion shaft 28 drives the threaded shaft 29 to rotate, thereby causing the threaded shaft 29 to drive the threaded sleeve 30 and the connecting spring shaft 31 to rotate, thereby causing the threaded sleeve 30 to drive the connecting spring shaft 31 and the sealing tube 32 to move, so that the connecting spring shaft 31 is in a contracted state to apply pressure to the sealing tube 32, thereby making the two groups of sealing tubes 32 fit and fixedly connected, and the inside of the sealing tube 32 will also seal the junction between the protective sleeve 26 and the two groups of antibacterial tube layers 4.

[0056] Working principle: When using rare earth antibacterial PE water supply pipe, first connect the pipe body 1 with the fixing seat 2, then connect the right end of the pipe body 1 with the connecting mechanism 3, so that the pipe body 1 is connected to another set of pipe bodies 1 through the connecting mechanism 3. When the pipe body 1 is subjected to external pressure, the fixing seat 2 will cooperate with the pipe body 1 to resist the pressure;

[0057] When water or gas passes through the pipe body 1 again, the inner wall of the antibacterial tube layer 4 will adhere to the water or gas, so that bacteria inside the water or gas will not adhere to the inner wall of the antibacterial tube layer 4 and corrode the pipe body 1. When the pipe body 1 itself is subjected to external pressure, the support damper 6 will drive the support pipe sheet 7 to shrink, so that the buffer layer 9 supports the support pipe sheet 7 and the bonding pipe sheet 8, so that the bonding pipe sheet 8 cooperates with the buffer layer 9 to buffer the pressure, thereby reducing the pressure on the antibacterial tube layer 4 and the fixed tube 5, thereby preventing the pipe body 1 from being deformed or ruptured.

[0058] When the two groups of pipe bodies 1 are connected to each other, the antibacterial tube layer 4 extending from the right end of the pipe body 1 can be connected to the inside of the connecting mechanism 3, so that the antibacterial tube layers 4 extending from the inside of the two groups of pipe bodies 1 pass through the first flange 17 and the second flange 21 and fit together, and then the first sealing ring 18 and the second sealing ring 19 are fit together, and at the same time, the first sealing ring 18 and the second sealing ring 19 are connected by the second connecting bolt 20, so that the first sealing ring 18 and the second sealing ring 19 seal and fix the fitting part of the antibacterial tube layers 4 extending from the two groups of pipe bodies 1.

[0059] Thereby completing a series of tasks, the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
