Description

Technical Field

[0001] The utility model relates to the technical field of hoses, in particular to a lightweight and corrosion-resistant hose. Background Technique

[0002] Hoses are important components in modern industry. Hoses are mainly used as wire and cable protection tubes for wires, cables, and automated instrument signals, as well as civilian shower hoses. During use, hoses are prone to corrosion by internal and external fluids. Therefore, corrosion-resistant materials are often used in hoses to improve their corrosion resistance.

[0003] For example, in the utility model: "A corrosion-resistant hose", the publication number is: "CN219102272U". This patent has an excellent weather resistance and flexural performance through the provided silicone rubber hose. The material of the provided reinforcement layer is formed by winding thin sheet steel, which has a bending effect. However, during the implementation of this patent, when the hose is affected by extrusion force, the reinforcement layer cannot effectively buffer the extrusion force and quickly recover, making the overall hose prone to deformation under force, and the compressive capacity of the hose is poor. Moreover, the reinforcement layer formed by winding thin sheet steel makes the overall weight of the hose relatively large and inconvenient to use. Therefore, there is an urgent need for a new type of lightweight and corrosion-resistant hose to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a lightweight and corrosion-resistant hose to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A lightweight and corrosion-resistant hose, including a polytetrafluoroethylene tube and a pressure-resistant protective outer rubber tube sleeve, characterized in that: A stainless steel wire mesh sleeve is installed on the outside of the polytetrafluoroethylene tube, and a pressure-resistant protective outer rubber tube sleeve is installed on the outside of the stainless steel wire mesh sleeve. Elastic rubber rings are evenly installed inside the pressure-resistant protective outer rubber tube sleeve. One end of the polytetrafluoroethylene tube is installed with a connecting outer tube, and an outer clamping member is installed on the outside of the connecting outer tube.

[0006] Preferably, a connecting flange is installed on the outside of the connecting outer tube.

[0007] Preferably, elastic rubber sheets are installed inside the elastic rubber rings.

[0008] Preferably, heat insulation cotton is provided inside the pressure-resistant protective outer rubber tube sleeve.

[0009] Preferably, a first corrosion-resistant layer is provided on the inner side of the polytetrafluoroethylene tube.

[0010] Preferably, a second corrosion-resistant layer is provided on the outside of the pressure-resistant protective outer rubber tube sleeve.

[0011] Preferably, the cross-sectional shapes of the elastic rubber sheets are all "S"-shaped.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The lightweight and corrosion-resistant hose is equipped with a stainless steel wire mesh sleeve, a first corrosion-resistant layer, and a polytetrafluoroethylene tube. When in use, the outside of the polytetrafluoroethylene tube can be reinforced by the stainless steel wire mesh sleeve, which is beneficial to improving the overall structural strength, and the corrosion-resistant effect can be improved through the first corrosion-resistant layer, which is beneficial to extending the service life of the polytetrafluoroethylene tube;

[0014] 2. The lightweight and corrosion-resistant hose is equipped with a pressure-resistant protective outer rubber tube sleeve, elastic rubber rings, and elastic rubber sheets, and heat-insulating cotton is filled inside the pressure-resistant protective outer rubber tube sleeve. The inside of the pressure-resistant protective outer rubber tube sleeve is hollow, which can reduce the overall weight. When being squeezed, the elastic rubber rings and elastic rubber sheets are deformed by the force, which can buffer the squeezing force and reduce the influence of the squeezing force on the polytetrafluoroethylene tube. After the squeezing ends, through the elastic action of the elastic rubber rings and elastic rubber sheets, the pressure-resistant protective outer rubber tube sleeve can be quickly restored, making the polytetrafluoroethylene tube not easily deformed or damaged, which is beneficial to improving the compressive effect of the lightweight and corrosion-resistant hose;

[0015] 3. The lightweight and corrosion-resistant hose is equipped with a connecting flange, a connecting outer tube, and an external clamping member. When in use, the connecting flange can be connected to an external pipeline, etc., and the fluid can be guided into the polytetrafluoroethylene tube through the connecting outer tube, so as to facilitate the connection of the polytetrafluoroethylene tube with the external pipeline.

The heat-insulating effect can be improved through the heat-insulating cotton 8. And when the lightweight and corrosion-resistant hose is squeezed, the elastic rubber rings 10 and the elastic rubber sheets 11 are deformed by the force, which can buffer the squeezing force and reduce the influence of the squeezing force on the polytetrafluoroethylene tube 6. And after the squeezing ends, through the elastic action of the elastic rubber rings 10 and the elastic rubber sheets 11, the pressure-resistant protective outer rubber tube sleeve 7 can be quickly restored, so that the polytetrafluoroethylene tube 6 is not easily deformed and damaged, which is beneficial to improving the compressive effect of the lightweight and corrosion-resistant hose.

[0024] As Figures 1-4 shown, a first corrosion-resistant layer 5 is arranged inside the polytetrafluoroethylene tube 6, and a second corrosion-resistant layer 9 is arranged outside the pressure-resistant protective outer rubber tube sleeve 7.

[0027] During use, the outer side of the polytetrafluoroethylene tube 6 can be reinforced by the stainless steel mesh sleeve 4, which is beneficial to improving the overall structural strength. Moreover, the corrosion resistance effect can be improved by the first corrosion-resistant layer 5 and the second corrosion-resistant layer 9, which is beneficial to extending the service life of the polytetrafluoroethylene tube 6;

[0028] Meanwhile, the heat preservation effect can be improved by the heat preservation cotton 8. And when the lightweight and corrosion-resistant hose is squeezed, the elastic rubber ring 10 and the elastic rubber sheet 11 are deformed by the force, which can buffer the extrusion force and reduce the influence of the extrusion force on the polytetrafluoroethylene tube 6. Moreover, after the extrusion ends, through the elastic action of the elastic rubber ring 10 and the elastic rubber sheet 11, the pressure-resistant protective outer rubber tube sleeve 7 can be quickly restored, so that the polytetrafluoroethylene tube 6 is not easily deformed or damaged, which is beneficial to improving the compressive effect of the lightweight and corrosion-resistant hose.
