Description

Technical Field

[0001] This utility model relates to the field of building water supply and drainage pipeline technology, and specifically discloses a spiral flow guiding structure PPR pipe fitting. Background Technology

[0002] PPR pipes have been widely used in the construction, municipal, industrial, and agricultural sectors due to their numerous advantages, including energy and material savings, environmental friendliness, lightweight yet high strength, corrosion resistance, smooth inner walls that prevent scaling, ease of construction and maintenance, and long service life. These advantages include applications in building water supply and drainage, urban and rural water supply and drainage, urban gas supply, power and fiber optic cable sheathing, industrial fluid transportation, and agricultural irrigation. However, in actual use, ordinary PPR pipe fittings still have some issues that need improvement. For example, when water flows inside the fittings, turbulence can easily occur, increasing flow resistance and affecting not only water transport efficiency but also potentially wasting energy. Simultaneously, the impact of turbulent flow on the inner wall of the fittings is intensified, which may reduce the long-term lifespan of the fittings. Furthermore, in applications with high water quality requirements, bacteria and other microorganisms can easily grow inside the fittings, causing water pollution. Utility Model Content

[0003] This utility model proposes a spiral flow guiding structure PPR pipe fitting. Through the spiral flow guiding part and its convex rib design on the inner wall, it can effectively reduce fluid resistance, reduce turbulence and noise, while enhancing the structural strength of the pipe body. Furthermore, the nano antibacterial layer improves the hygiene performance, achieving efficient, stable and durable fluid transportation.

[0004] This utility model is implemented as follows: a spiral flow guiding structure PPR pipe fitting includes a pipe body, the inner wall of which is provided with a spiral flow guiding part, which extends from one end of the pipe body to the other end; the spiral flow guiding part includes at least three convex ribs that spirally extend along the axial direction of the pipe body, and a flow guiding channel is formed between adjacent convex ribs; the cross-section of the convex rib is trapezoidal, the height of the convex rib is 1 / 8-1 / 6 of the inner diameter of the pipe body, and the helix angle is 15°-30°; the pipe body and the spiral flow guiding part are integrally injection molded.

[0005] As a preferred embodiment of the spiral flow guiding structure PPR pipe fitting of this utility model, the spiral trajectory of the convex ribs is an equidistant spiral line, and all the convex ribs have the same spiral parameters.

[0006] As a preferred embodiment of the spiral flow guiding structure PPR pipe fitting of this utility model, the surface of the convex rib facing the flow is an inwardly concave arc surface, and the surface of the rib facing away from the flow is an outwardly convex arc surface.

[0007] As a preferred embodiment of the spiral flow guiding structure PPR pipe fitting of this utility model, the water inlet end of the pipe body is provided with a tapered flow guide, the taper angle of which is 30°-45°.

[0008] As a preferred embodiment of the spiral flow guiding structure PPR pipe fitting of this utility model, the inner wall of the conical flow guiding port is provided with an annular flow guiding groove, the depth of which is 1 / 3 to 1 / 2 of the height of the rib.

[0009] As a preferred embodiment of the spiral flow guiding structure PPR pipe fitting of this utility model, the outer wall of the pipe is provided with axial reinforcing ribs, and the number of the reinforcing ribs is consistent with the number of the protruding ribs and their positions correspond.

[0010] As a preferred embodiment of the spiral flow guiding structure PPR pipe fitting of this utility model, both the inner wall of the pipe body and the flow guiding surface of the spiral flow guiding part are provided with a nano antibacterial layer, which is a silver-loaded titanium dioxide coating.

[0011] The beneficial effects of this utility model are:

[0012] 1. Through the synergistic effect of structures such as spiral guide section, convex rib, conical guide port and annular guide groove, the water flow forms a stable and orderly spiral flow in the pipe, which greatly reduces the water flow resistance. Compared with ordinary PPR pipe fittings, it can significantly improve the water flow transmission efficiency and reduce energy consumption.

[0013] 2. The spiral flow of water impacts the inner wall of the pipe more evenly, reducing damage to the inner wall caused by excessive local impact; at the same time, the axial reinforcing ribs on the outer wall of the pipe enhance the structural strength of the pipe body and improve the compressive strength of the pipe fitting. These factors work together to effectively extend the service life of the pipe fitting.

[0014] 3. The nano-antibacterial layer set on the inner wall of the pipe and the flow guide surface of the spiral guide section can effectively inhibit bacterial growth, prevent water quality from being polluted, and ensure that the transported water always maintains good hygienic quality, providing a reliable guarantee for scenarios with high water quality requirements such as drinking water transportation.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figures 1-5 A spiral flow guiding structure PPR pipe fitting includes a pipe body 1, with a spiral flow guiding section 2 provided on the inner wall of the pipe body 1, extending from one end of the pipe body 1 to the other end; the spiral flow guiding section 2 includes at least three convex ribs 3 extending spirally along the axial direction of the pipe body 1, and a flow guiding channel 4 is formed between adjacent convex ribs 3; the cross-section of the convex rib 3 is trapezoidal, the height of the convex rib 3 is 1 / 8-1 / 6 of the inner diameter of the pipe body 1, and the spiral helix angle is 15°-30°; the pipe body 1 and the spiral flow guiding section 2 are integrally injection molded.

[0024] In this embodiment: when water enters the pipe body 1, it first passes through the conical guide port 7 at the inlet end. The conical guide port 7 initially converges and guides the water flow, allowing it to enter the pipe body 1 in a relatively orderly manner. Subsequently, the water flow contacts the spiral guide section 2 on the inner wall of the pipe body 1. Guided by the ribs 3, the water flow begins to flow along the spiral path, forming a spiral flow. Due to the special design of the ribs 3, including the trapezoidal cross section, specific height and spiral angle, equidistant spiral lines, and special front and back flow arc surfaces, the water flow remains stable and orderly during the spiral flow, effectively reducing the water flow resistance. At the same time, the annular guide groove 8 on the inner wall of the conical guide port 7 further optimizes the water flow state, allowing it to better integrate with the spiral flow inside the pipe. The axial reinforcing ribs 9 on the outer wall of the pipe body 1 disperse pressure and enhance the structural strength of the pipe body 1 when the water flow exerts pressure on the inner wall of the pipe. The nano-antibacterial layer 10 on the inner wall of the pipe body 1 and the guide surface of the spiral guide section 2 continuously inhibits bacterial growth, ensuring water quality.

[0025] The rib 3 guides the water flow to form a spiral flow within the pipe body 1, changing the original turbulent state of the water flow and making it more orderly, thereby effectively reducing water flow resistance and improving water transport efficiency. At the same time, the spiral flow of water has a more uniform impact on the inner wall of the pipe body 1, reducing the situation of excessive local impact and helping to extend the service life of the pipe fittings. The trapezoidal cross-section design ensures the structural strength of the rib 3 while helping to guide the water flow to form a stable spiral flow. The specific range of height and spiral angle can enable the water flow to form a more ideal spiral motion state within the pipe, further optimizing the flow guiding effect.

[0026] As a technical optimization of this utility model, the spiral trajectory of the convex rib 3 is an equidistant spiral, and all the convex ribs 3 have the same spiral parameters.

[0027] In this embodiment, the equidistant spirals and identical spiral parameters ensure that the water flow is consistent at all positions within the pipe, thereby improving the stability of the water flow.

[0028] As a technical optimization of this utility model, the frontal surface 5 of the rib 3 is an inwardly concave arc surface, and the backal surface 6 is an outwardly convex arc surface.

[0029] In this embodiment, the design of the concave arc surface on the upstream side and the convex arc surface on the downstream side helps to reduce the energy loss of the water flow when it passes through the convex rib 3, reduce the water flow resistance, and at the same time make the water flow more smoothly along the spiral path.

[0030] As a technical optimization of this utility model, the water inlet end of the pipe body 1 is provided with a conical guide port 7, the taper angle of which is 30°-45°.

[0031] In this embodiment: when the water flows into the pipe body 1, the conical guide port 7 can play a preliminary role in converging and guiding the water flow, so that the water flows more smoothly into the interior of the pipe body 1, reducing the impact of the water flow and the generation of turbulence, and further improving the water flow delivery efficiency.

[0032] As a technical optimization of this utility model, the inner wall of the conical guide port 7 is provided with an annular guide groove 8, and the depth of the annular guide groove 8 is 1 / 3-1 / 2 of the height of the convex rib 3.

[0033] In this embodiment, the annular guide groove 8 can further subdivide and guide the water flow entering the pipe body 1, so that the water flow can better adapt to the guiding effect of the spiral guide part 2 inside the pipe, optimize the flow state of the water flow in the pipe, and reduce the water flow resistance.

[0034] As a technical optimization of this utility model, the outer wall of the tube body 1 is provided with axial reinforcing ribs 9, the number of reinforcing ribs is the same as the number of protruding ribs 3 and their positions correspond.

[0035] In this embodiment, the axial reinforcing rib 9 can significantly enhance the structural strength of the pipe body 1 and improve the compressive strength of the pipe fitting, making it less prone to deformation or damage when subjected to greater pressure, thereby extending the service life of the pipe fitting. At the same time, the design corresponding to the position of the convex rib 3 helps to better disperse the pressure through the reinforcing rib on the outer wall when the water flow inside the pipe body 1 exerts pressure on the inner wall of the pipe, thereby improving the overall stability of the pipe fitting.

[0036] As a technical optimization of this utility model, both the inner wall of the tube body 1 and the flow guiding surface of the spiral flow guiding part 2 are provided with a nano antibacterial layer 10, which is a silver-loaded titanium dioxide coating.

[0037] In this embodiment, the nano antibacterial layer 10 can effectively inhibit the growth and reproduction of bacteria and other microorganisms on the inner wall of the pipe body 1 and the guide surface of the spiral guide part 2, prevent water quality from being polluted, and ensure that the transported water maintains good hygienic quality. It is especially suitable for scenarios such as drinking water transportation with high water quality requirements.

[0038] Working principle and usage process of this utility model:

[0039] When water enters the spiral guide structure PPR pipe fitting, it first passes through the inlet end of the pipe body 1. The conical guide port 7 initially converges and guides the dispersed water flow, allowing it to flow more smoothly into the pipe body 1. At this time, the annular guide groove 8 on the inner wall of the conical guide port 7 further subdivides and guides the water flow, cutting it into more uniform small streams, preparing for subsequent cooperation with the spiral guide section 2. After entering the pipe body 1, the water flows into contact with the spiral guide section 2 on the inner wall of the pipe body 1. The spiral guide section 2 has at least three axially spirally extending ribs 3. The concave arc surface on the flow-facing side and the convex arc surface on the flow-reverse side guide the water flow into the spiral track and propel it forward stably. The water flow continuously adjusts its posture in the guide channel 4 formed by adjacent ribs 3, transforming from a disordered state into a stable spiral flow. During the spiral flow of the water, the equidistant spiral lines and identical spiral parameters of the ribs 3 ensure that each position inside the pipe... The water flow is uniform and consistent, avoiding local turbulence, and the impact of the water flow on the inner wall of the pipe body 1 is more uniform, reducing damage to the inner wall. As the water flow spirals along the guide channel 4, the axial reinforcing ribs 9 on the outer wall of the pipe body 1, which are the same number and corresponding in position as the ribs 3, disperse the pressure under the action of the water flow pressure, enhance the structural strength of the pipe body 1, and ensure that the pipe body 1 does not deform or get damaged under the water flow pressure, providing structural support for stable water delivery. The silver-loaded titanium dioxide nano-antibacterial layer 10 on the inner wall of the pipe body 1 and the guide surface of the spiral guide part 2 continuously inhibits the growth and reproduction of bacteria and other microorganisms on the inner wall and guide surface of the pipe body 1 from the moment the water flows into the pipe, ensuring water quality and hygiene, until the water flows smoothly out from the other end of the pipe body 1, completing the delivery process. Throughout the entire process, the axial reinforcing ribs 9 continuously ensure the structural strength of the pipe body 1.
