Description

Technical Field

[0001] This utility model relates to the field of PVC hoses, specifically to a multi-layer composite reinforced steel wire-free PVC hose. Background Technology

[0002] PVC hoses, widely used in daily life, play a vital role in water supply, cable protection, and industrial fluid transmission. Traditional PVC pipes are mostly made of single-layer PVC material, with a relatively simple manufacturing process. However, as the performance requirements for pipes in various sectors of modern society continue to increase, the limitations of single-layer PVC pipes are becoming increasingly apparent. Due to their limited functionality, possessing only basic flexibility, corrosion resistance, and a certain level of strength, they struggle to meet diverse needs in complex and varied application scenarios. For example, in outdoor garden irrigation, single-layer pipes lack UV resistance and are prone to aging, hardening, and cracking after prolonged exposure to sunlight. In industrial production, when used to transport high-temperature or corrosive liquids, single-layer pipes cannot provide effective heat insulation and protection, leading to a shortened service life. In some locations with high safety requirements, such as construction sites and flammable gas transportation environments, single-layer pipes lack both flame retardancy and antistatic properties, posing significant safety hazards.

[0003] More importantly, single-layer pipes have a simple structure and are difficult to expand in terms of functionality. Due to their limited internal space, they cannot accommodate the addition of different functional structural layers like multi-layer pipes, such as fiber braided layers to enhance pressure resistance, shielding layers to prevent electromagnetic interference, or insect-repellent layers to protect against pests. This makes single-layer PVC pipes significantly less adaptable, unable to meet the special performance requirements of pipes in different environments, and increasingly unable to adapt to the increasingly diverse needs of modern engineering construction and daily life applications.

[0004] Therefore, it is necessary to propose a multi-layer composite reinforced steel wire-free PVC hose. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer composite reinforced steel wire-free PVC flexible hose, including a tube body, a fixing tube sleeved at the end of the tube body, and fastening screws at both ends of the fixing tube. The fastening screws penetrate the fixing tube and contact the tube body. The tube body and the fixing tube are connected by threads. The tube body includes a base layer and an outer layer, and the outer layer is fixedly sleeved on the outside of the base layer.

[0007] The base layer is made of PVC material. The outer layer includes a tensile layer located outside the base layer. A pressure-resistant layer is provided outside the tensile layer. A heat-insulating layer is provided outside the pressure-resistant layer. An antibacterial layer is provided outside the heat-insulating layer. A conductive layer is provided outside the antibacterial layer. A fireproof layer is provided outside the conductive layer. A buffer layer is provided outside the fireproof layer.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] See attached document Figure 1 -Appendix Figure 4 The multi-layer composite reinforced steel wire-free PVC hose provided by this utility model includes a tube body 1, a fixing tube 2 sleeved at the end of the tube body 1, and fastening screws 3 at both ends of the fixing tube 2. The fastening screws 3 penetrate the fixing tube 2 and contact the tube body 1. The tube body 1 and the fixing tube 2 are connected by threads. The tube body 1 includes a base layer 101 and an outer layer, and the outer layer is fixedly sleeved on the outside of the base layer 101.

[0025] The base layer 101 is made of PVC material, and the outer layer includes a tensile layer 102, which is located outside the base layer 101. A pressure-resistant layer 103 is provided outside the tensile layer 102, a heat-insulating layer 104 is provided outside the pressure-resistant layer 103, an antibacterial layer 105 is provided outside the heat-insulating layer 104, a conductive layer 106 is provided outside the antibacterial layer 105, a fireproof layer 107 is provided outside the conductive layer 106, and a buffer layer 108 is provided outside the fireproof layer 107. Multiple insect repellent patches 4 are also fixedly embedded on the pipe body 1, and the insect repellent patches 4 are evenly distributed on the pipe body 1.

[0026] In this embodiment, the design of fastening screws 3 and fixing tubes 2 can adjust the length of the tube body 1 inserted into the fixing tube 2 to a certain extent, thereby adjusting the installation position of the tube body 1. Furthermore, by setting the tube body 1, which is composed of a base layer 101, a tensile layer 102, a pressure-resistant layer 103, a thermal insulation layer 104, and an antibacterial layer 105, the various performance characteristics of the tube body 1 are effectively improved.

[0027] To achieve the purpose of tensile and pressure resistance, the device adopts the following technical solution: both the tensile layer 102 and the pressure-resistant layer 103 are made of polyester fiber material. Polyester fiber has high strength and elastic modulus, is not easily deformed, and has good tensile properties. At the same time, polyester fiber also has good chemical corrosion resistance and wear resistance, and can maintain stable performance in different environments. Its flexibility is also good, and it can adapt to the bending and twisting of PVC hoses. It is often used in occasions where high flexibility and tensile performance are required.

[0028] In order to achieve the purpose of heat preservation, the device adopts the following technical solution: the heat preservation layer 104 is made of glass fiber cotton material. When it is necessary to transport high temperature or low temperature medium, the heat loss or absorption can be reduced through the heat preservation layer 104. Glass fiber cotton has a low thermal conductivity, which can effectively maintain the temperature of the medium inside the pipe and reduce energy consumption.

[0029] In order to achieve the purpose of antibacterial, the device adopts the following technical solution: the antibacterial layer 105 is made of silver ion antibacterial agent, which can inhibit the growth and reproduction of microorganisms such as bacteria and mold, prevent bacteria from growing inside the hose, and ensure the hygiene and safety of the transported medium.

[0030] In order to achieve the purpose of anti-static, the device adopts the following technical solution: the conductive layer 106 is made of conductive carbon black powder to prevent static electricity accumulation from causing safety accidents or affecting equipment operation. The conductive carbon black powder can make the hose have a certain conductivity and can dissipate the generated static electricity in time.

[0031] In order to achieve the purpose of flame retardancy and fire prevention, the device adopts the following technical solution: the fireproof layer 107 is made of triphenyl phosphate material, which has good flame retardant effect and plasticizing properties. When they burn, they form a dense carbonized layer, which prevents the transfer of oxygen and heat, thereby achieving the purpose of flame retardancy. At the same time, phosphate flame retardants can also improve the processing performance and flexibility of PVC hoses.

[0032] In order to improve the impact resistance and flexibility, the device adopts the following technical solution: the buffer layer 108 is made of ethylene propylene rubber. When the hose is subjected to external impact, the buffer layer 108 can absorb and disperse the impact force, reduce the damage to the internal structure of the hose, and make the hose more flexible, making it easier to bend and lay.

[0033] The usage process of this utility model is as follows: By designing a threaded connection between the pipe body 1 and the fixed pipe 2, the length of the pipe body 1 inserted into the fixed pipe 2 can be adjusted to a certain extent during actual use, thereby adjusting the length and installation position of the pipe body 1. Furthermore, the pipe body 1 is further fixed by the fastening screw 3 to prevent the pipe body 1 from loosening after long-term use. At the same time, by designing the pipe body 1, which is composed of a base layer 101, a tensile layer 102, a pressure-resistant layer 103, a heat insulation layer 104, an antibacterial layer 105, etc., the various performances of the pipe body 1 are effectively improved.

[0034] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
