Description

Technical Field

[0001] The utility model relates to the technical field of pipes, in particular to a PVC pipe. Background Art

[0002] PVC pipe refers to a pipe material supported by polyvinyl chloride resin.

[0003] PVC pipe is a common fluid channel pipe, especially a commonly used material for water pipes. Today's PVC pipes generally have corrosion resistance, making them more durable, making PVC pipes commonly used in household water pipes.

[0004] Water pipes used in homes are sometimes exposed or run directly on the ceiling. In this case, when water flows through the PVC pipe, the sound of the water will be transmitted directly, resulting in poor noise reduction effect of the PVC pipe. For this reason, we propose a PVC pipe that can reduce noise. Utility Model Content

[0013] Preferably, the first protection mechanism comprises a wear-resistant layer, and the wear-resistant layer is arranged on the outer wall of the outer tube.

[0014] Technical effects and advantages of the utility model:

[0015] The utility model makes the PVC pipe stronger and more durable by configuring the PVC pipe to be a double-layer structure consisting of an outer pipe and an inner pipe. At the same time, the sound-proof cotton braided layer arranged between the outer pipe and the inner pipe can reduce the propagation of sound. The sound-proof cotton braided layer is a porous structure that can absorb sound waves and reduce their propagation. Therefore, when the PVC pipe is in use, the sound of water flow in the pipe is not easy to be transmitted. Therefore, the use of the PVC pipe in household water pipes will not affect the residence, thereby improving the functionality of the PVC pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-2 A PVC pipe shown includes an outer pipe 101 and an inner lining mechanism, wherein the inner lining mechanism is arranged inside the outer pipe 101, and the inner lining mechanism includes an inner pipe 201, wherein the inner pipe 201 is inserted inside the outer pipe 101, and a sound-proof cotton braided layer 202 is arranged between the inner pipe 201 and the outer pipe 101, and a first reinforcing mechanism is arranged inside the inner pipe 201, and a first protective mechanism is arranged on the outer wall of the outer pipe 101. By arranging the PVC pipe into a double-layer structure consisting of the outer pipe 101 and the inner pipe 201, the PVC pipe is made stronger and more durable. At the same time, the sound-proof cotton braided layer 202 arranged between the outer pipe 101 and the inner pipe 201 can reduce the propagation of sound. The sound-proof cotton braided layer 202 is a porous structure that can absorb sound waves and reduce their propagation, so that when the PVC pipe is in use, the sound of water flow inside it is not easy to be transmitted, so that the use of the PVC pipe in household water pipes will not affect the home, thereby improving the functionality of the PVC pipe.

[0021] Among them, the first reinforcement mechanism includes a reinforcement layer 301, and the reinforcement layer 301 is arranged on the inner wall of the inner tube 201. The inner wall of the reinforcement layer 301 is provided with a second protective mechanism. The material of the reinforcement layer 301 is fiber reinforced plastic. Fiber reinforced plastic is a composite material, mainly composed of a plastic matrix and a fiber reinforcement. The plastic matrix is ​​usually a resin, such as a polyester resin, an epoxy resin or a phenolic resin. Fiber reinforced plastic has the advantages of high strength and rigidity, light weight, corrosion resistance and insulation. Due to the addition of fiber reinforcement, fiber reinforced plastic has higher strength and rigidity than many traditional materials. Compared with metals, fiber reinforced plastic is usually lighter, which makes it very useful in applications that require light weight but strength. Fiber reinforced plastic has good resistance to many chemicals and corrosive environments, so that it can be used for a long time in various applications.

[0022] The second protection mechanism includes an anti-corrosion layer 401, which is arranged on the inner wall of the reinforcement layer 301. The inner wall of the anti-corrosion layer 401 is provided with a pressure-resistant mechanism. The material of the anti-corrosion layer 401 is polyester fiber, which has good chemical resistance and corrosion resistance. The molecular structure of the polyester fiber makes it have good stability under common chemical substances. They have high resistance to common solvents and chemicals such as water, acid, and alkali, and are not easily corroded or dissolved by these chemicals. The surface of polyester fiber is usually relatively inert and not easy to react chemically with other substances, so it is not easy to be corroded. Polyester fiber usually has high physical strength and durability. Even when it is subject to a certain degree of corrosion or wear, its structure can remain relatively stable, thereby extending its service life.

[0023] Among them, the pressure-resistant mechanism includes a fixed ridge 601, which is fixedly connected to the inner wall of the anti-corrosion layer 401, and the fixed ridge 601 is spirally arranged. A second reinforcing mechanism is arranged inside the fixed ridge 601. The spiral fixed ridge 601 is arranged, and the fixed ridge 601 is continuously arranged, so that after the PVC pipe is squeezed, the pressure resistance of the PVC pipe is stronger and it is not easy to be crushed, thereby ensuring that the PVC pipe can be used stably, avoiding the phenomenon of PVC pipe blockage caused by squeezing and deformation, thereby improving the stability of the use of the PVC pipe.

[0024] Among them, the second reinforcement mechanism includes a reinforcement rib 602, which is fixedly inserted and connected to the inside of the fixed convex strip 601. The reinforcement rib 602 is made of metal and is used in conjunction with the fixed convex strip 601 to make the pressure-resistant mechanism more resilient, thereby making the PVC pipe more resistant to deformation.

[0025] Among them, the first protective mechanism includes a wear-resistant layer 501, which is arranged on the outer wall of the outer tube 101. The material of the wear-resistant layer 501 is ceramic particles. Ceramic particles usually have good wear resistance, hardness, pressure resistance, chemical stability and thermal stability. Ceramic particles usually have very high hardness, which enables them to resist wear when in contact with other surfaces. Common ceramic materials such as aluminum oxide and silicon carbide have very high hardness, so they can maintain the integrity of the surface when subjected to friction or wear. Ceramic particles have good pressure resistance and can withstand greater pressure without easily breaking or deforming, which enables them to maintain the flatness and shape of the surface and reduce wear when subjected to external forces. Many ceramic materials have good chemical stability and are not easily eroded or corroded by chemicals, which enables them to maintain durability for a long time in various harsh environments. Some ceramic materials have good thermal stability and can maintain their structure and performance unchanged in high temperature environments, which enables them to still maintain good wear resistance under high temperature friction or wear conditions.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
