Description

Technical Field

[0001] This utility model relates to the field of spiral pipe technology, and in particular to a PVC spiral pipe with raised ribs. Background Technology

[0002] PVC spiral wound pipe, also known as PVC steel wire spiral reinforced pipe, is a type of pipe made of rigid polyvinyl chloride with embedded spiral steel wires to improve its strength and pressure resistance.

[0003] For example, CN206145285U discloses a novel high-polymer PVC spiral pipe, which includes a pipe body. The inner wall of the pipe body is provided with spiral protrusions. The thickness of the spiral protrusions is three centimeters, and the spiral distance between the spiral protrusions is ten centimeters. The pipe body includes a bottom anti-corrosion layer, an anti-aging layer wrapped on the outer surface of the anti-corrosion layer, an anti-deformation layer wrapped on the outer surface of the anti-aging layer, and thirty equilateral triangular steels and thirty inverted triangular steels arranged in a ring array within the anti-deformation layer.

[0004] In existing technologies, spiral pipes have weak resistance to external pressure, especially the double-walled hollow structure. When buried, they are easily deformed and cracked due to soil pressure, vehicle rolling, or foundation settlement. At the same time, there are dead corners in the inner wall of the pipe, which are prone to the growth of bacteria, mold and other microorganisms due to the humid environment, leading to water pollution. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing spiral pipes having weak resistance to external pressure, being prone to deformation and cracking, and having dead corners in the inner wall of the pipe that easily breed bacteria, mold and other microorganisms, leading to water pollution. Therefore, a ribbed PVC spiral pipe is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ribbed PVC spiral pipe, comprising a spiral pipe body, a docking mechanism fixedly connected to the end of the spiral pipe body, the spiral pipe body comprising a crack-resistant outer layer, an inner layer compositely connected to the inner side of the crack-resistant outer layer, a hollow layer provided between the crack-resistant outer layer and the inner layer, radial support ribs provided inside the hollow layer, transverse support ribs fixedly connected between adjacent radial support ribs, the transverse support ribs being arranged in a uniform annular array with the center line of the radial support ribs as the axis, an antibacterial layer compositely connected to the inner side of the inner layer, and a noise reduction layer compositely connected to the inner side of the antibacterial layer.

[0007] Preferably, the inner ring surface of the noise reduction layer has a spiral groove, and a spiral rib is installed inside the spiral groove.

[0008] Preferably, the spiral rib has a spiral steel wire inside.

[0009] Preferably, the docking mechanism includes a first pair of interfaces and a second pair of interfaces, one end of the first pair of interfaces is fixedly connected to one end of the spiral tube body, and the other end of the spiral tube body is fixedly connected to one end of the second pair of interfaces.

[0010] Preferably, the other end of the first pair of interfaces has a mating groove, and the other end of the second pair of interfaces is inserted into the mating groove.

[0011] Preferably, a first sealing ring is fixedly connected to the outer surface of the second pair of interfaces, the outer surface of the first sealing ring is provided with barbs, and a second sealing ring is fixedly connected to the inner annular surface of the second pair of interfaces.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the spiral pipe body is provided with an anti-crack outer layer, an inner layer, an antibacterial layer, and a noise reduction layer from the outside to the inside. The radial support ribs and transverse support ribs can improve the resistance to external pressure. The hollow layer is filled with sound-absorbing material to reduce noise. The antibacterial layer is made of PVC material with added silver ion antibacterial agent. The inner wall is coated with a thick nano titanium dioxide photocatalytic coating to inhibit the growth of microorganisms on the inner wall of the pipe and decompose organic pollutants. The noise reduction layer is made of rubber material to absorb the vibration noise generated by the water flow impact. The inner ring surface of the noise reduction layer has spiral grooves, which form a three-dimensional flow guiding network with the spiral ribs, which can reduce water flow resistance and reduce the probability of scale adhesion.

[0014] 2. In this utility model, the second pair of interfaces is fixed by inserting and connecting the mating groove. The second sealing ring on the inner side of the second pair of interfaces is a soft rubber ring, which provides a sealing effect. The first sealing ring on the outer side is a hard rubber ring, which provides auxiliary fixation. At the same time, multiple barbs are provided on the outer surface of the first sealing ring, which are opposite to the direction of pipe insertion. The first sealing ring will bite the inner wall of the mating groove, and prevent the pipe from being pulled out excessively through mechanical locking, thereby improving the connection sealing effect.
