Description

A gas hose with mixed-braided reinforcement layer and its process

Technical Field

The invention relates to the technical field of pipes, and in particular to a gas hose with a mixed-braided reinforcement layer and a process thereof.

Background Art

At present, gas pipes on the market usually have a single-layer structure and a multi-layer structure. With the improvement of people's safety awareness, gas pipes are mostly multi-layer structures, which include an inner rubber layer, a reinforcement layer and an outer rubber layer. In terms of performance, the inner rubber layer needs to meet the requirements of gas corrosion resistance and low permeability, the outer rubber layer needs to have sufficient wear resistance, and the reinforcement layer determines the overall strength and pressure resistance of the gas pipe. Although the reinforcement layer of the gas pipe provides a certain structural strength for the gas pipe, due to the different permeabilities of the inner and outer rubber layers and the time difference between the inner and outer penetrations, the gas that penetrates the inner layer is more and has a greater pressure, while the gas that penetrates the outer layer is relatively less, so the pressure is smaller, resulting in the accumulation of the seeped gas at the relatively weak adhesion between the inner and outer layers, thereby forming a bulge, affecting the adhesion between the inner and outer layers. The reinforcement layer of the gas pipe in the prior art is usually composed of woven layers of different materials, and the tension between different woven layers is unequal, which further leads to the bulging phenomenon, seriously affecting the safe use of the gas pipe.

Summary of the invention

In view of the deficiencies in the prior art, an object of the present invention is to provide a gas hose with a mixed-braided reinforcement layer, which effectively increases the structural strength of the gas hose.

The above technical objectives of the present invention are achieved through the following technical solutions: A gas hose with a mixed reinforcement layer, including:

An inner rubber hose, which is a corrosion-resistant hollow pipe used to transmit gas and withstand gas pressure;

A mixed-woven reinforcement layer, comprising a woven warp thread group and a woven weft thread group, wherein the woven warp thread group is composed of at least two parallel first warp threads, and the woven weft thread group is composed of at least two parallel first weft threads;

At least one metal wire is arranged parallel to or sandwiched between the first warp and the first weft along their arrangement direction, and the braided warp group, the braided weft group and the metal wire overlap each other and are tightly wrapped outside the middle rubber tube;

Furthermore, it also includes a wear-resistant layer, which surrounds and densely mixes the reinforcing layer.

Furthermore, compression convex layers are respectively provided on the inner wall of the wear-resistant layer corresponding to the woven warp group and the woven weft group; and compression concave layers are respectively provided on the outer barrier layer corresponding to the woven warp group and the woven weft group. Through the above improvements, a certain installation positioning is provided for the mixed-woven reinforcement layer. The compression concave layer is beneficial to the weaving and forming of the mixed-woven reinforcement layer on the middle rubber hose, and the compression convex layer is beneficial to the dense mixed-woven reinforcement layer of the wear-resistant layer, thereby ensuring the structural stability of the mixed-woven reinforcement layer.

Furthermore, the mixed-woven reinforcement layer is composed of a plurality of fully cyclic structures, the structure points of the first warp along its arrangement direction are two up and two down, the structure points of the first weft along its arrangement direction are two down and two up, and the structure points of the metal wire in the warp direction are two up and two down.

Furthermore, it also includes a middle rubber hose arranged outside the inner reinforcement layer, the middle rubber hose includes a tightly fitted inner barrier layer and an outer barrier layer; the inner barrier layer is a blended layer of plastic and rubber materials, the outer barrier layer is a plastic material layer, and the inner reinforcement layer is bonded between the inner wall of the inner barrier layer and the outer wall of the inner rubber hose. Through the above improvements, the tensile strength, oil resistance and gas guidance of the inner barrier layer are increased by blending plastic and rubber materials.

Furthermore, the metal wire has a first, second and third spiral position along its arrangement direction. The metal wire is located on one side of the first warp and/or the first weft in parallel at the first spiral position; the metal wire is located between two first warp threads and/or two first weft threads at the second spiral position; the metal wire is located on the other side of the first warp and/or the first weft in parallel at the third spiral position. Through the above improvements, the metal wire is arranged on both sides of the first warp and the first weft at the first spiral position and the third spiral position, so that the metal wire tightens the first warp in the warp direction and tightens the first weft in the weft direction, making the structure of the mixed reinforcement layer tighter. The metal wire presses the first warp and the first weft at the second spiral position. When the second spiral position is between two warp tissue points and two weft tissue points of the fully cyclic tissue, it can also be located on a warp tissue point or a weft tissue point.

Furthermore, the first warp and the first weft both include a connecting wire and at least two strands of high-strength chemical fibers, and the high-strength chemical fibers are respectively wound on the connecting wire along different rotation directions. Through the above improvements, multiple strands of high-strength chemical fibers are wound on the connecting wire to form the first warp and the first weft, thereby ensuring the structural strength of a single first warp and the first weft, and the connecting wire can be made of metal or high-strength chemical fiber.

Furthermore, two adjacent braided warp groups and two adjacent braided weft groups are parallel to each other and have gaps therebetween. The metal wires are arranged to fill the gaps and are staggered at the warp points of the two adjacent first warp threads.

Furthermore, the diameter ratio of the second warp thread to the first warp thread is 1:5, the diameter ratio of the second weft thread to the first weft thread is 1:5, and the diameter ratio of the connecting wire to the metal wire is 1:4.

Furthermore, the angle between the second longitude and the second latitude is set to 60 to 90 degrees; the angle between the first longitude and the first latitude is set to 45 to 90 degrees.

A process for producing a gas hose having a mixed reinforcement layer comprises the following steps:

a. A traction wheel, a first tension control device and a take-up drum are sequentially arranged, and a plurality of first tension rollers are arranged at intervals on both sides of the first tension control device to adjust the upper and lower spacing and the front and rear spacing of each tension roller, and the second warp drum and the second weft drum with the same tension are gathered on the take-up drum;

b. Extrude the plastic material layer and the bonding layer of the inner hose, and weave the inner reinforcement layer on the surface of the bonding layer; extrude the inner barrier layer and the outer barrier layer of the middle hose and bond them together, and densely cover the inner barrier layer on the bonding layer and the inner reinforcement layer;

c. A plurality of high-strength chemical fibers are spirally twisted on the connecting wire to form a first warp and a first weft;

d. A traction wheel, a second tension control device and a wire take-up drum are sequentially arranged, a plurality of second tension rollers and a third tension roller are arranged at intervals on both sides of the second tension control device, at least two first warps or at least two first wefts are arranged side by side on the second tension roller, a metal wire is arranged on the third tension roller, the metal wire is parallel to the first warp or the first weft, the front-to-back spacing and the upper-lower spacing of the second tension roller and the third tension roller are regulated, and a mixed wire drum of metal wire and high-strength chemical fiber with consistent tension is gathered on the same wire take-up drum, which are the first warp drum and the first weft drum respectively;

e. A mixed braided reinforcement layer is woven outside the middle rubber layer, and a wear-resistant layer is densely coated outside the mixed braided reinforcement layer.

Compared with the prior art, the present invention has the following advantages and beneficial effects:

1. By mixing high-strength chemical fiber and metal wire, the metal wire increases the structural strength of the gas pipe as a whole, effectively preventing rodents such as mice from gnawing on the gas pipe, reducing safety hazards, and the gaps between the high-strength chemical fiber threads provide guidance for the accumulated gas, allowing the infiltrated gas to seep out from both ends of the gas pipe;

2. An inner reinforcement layer is arranged outside the inner rubber hose. Since the gas first seeps out from the inner rubber hose, it has a relatively large pressure. The inner reinforcement layer made of a single material of high-strength chemical fiber weave guides the seeping gas to seep out from the end of the gas hose along the arrangement direction of the second warp and the second weft, thereby effectively reducing the bulging phenomenon of the gas between the middle rubber layer and the inner rubber layer;

3. The mixed reinforcement layer is provided with at least two first warps in the warp direction and at least two first wefts in the weft direction. Metal wires are arranged in parallel on one side of the first warps and the first wefts to reduce the floating gap caused by the tension difference between the metal wires and the high-strength chemical fibers. The metal wires squeeze the first warps and the first wefts on the surface of the middle rubber hose to tighten the tightness of the mixed reinforcement layer. The metal wires are combined with the high-strength chemical fibers to ensure the structural strength and anti-twisting and anti-extrusion capabilities of the gas hose. At the same time, the intersection between the first warps, the first wefts and the metal wires constitutes another drainage channel for the gas, ensuring that the infiltrated gas is output to both ends of the gas hose along the arrangement direction of the first warps or the first wefts, thereby effectively avoiding the accumulation of gas between the functional layers of the gas hose.

4. The braided warp group, the braided weft group and the metal wire tighten the middle rubber layer, increase the density between the inner barrier layer and the outer barrier layer of the middle rubber layer, eliminate the adhesion and gap between the inner reinforcement layer and the middle rubber layer, and the wear-resistant layer further densifies each functional layer of the gas hose while ensuring the wear resistance of the outer surface of the gas hose, reducing the floating gap caused by the tension on the organization point of the inner reinforcement layer and the mixed reinforcement layer;

5. The two first warps and the two first wefts are arranged in parallel to reduce the height difference of the organization points in the warp and weft directions. By increasing the number of parallel metal wires, the vacant area between adjacent first warps and first wefts is reduced, the structural tightness of the mixed reinforcement layer and the degree of coverage of the mixed reinforcement layer on the medium rubber hose are increased, and the overall structural strength of the gas hose is improved, with low elongation and expansion coefficients.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

It should be understood that although the terms upper, middle, lower, one end, etc. appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

The longitude and latitude referred to in the present invention are relative longitude and relative latitude, not absolute longitude and absolute latitude.

As shown in FIG1-5, a gas hose with a mixed reinforcement layer includes:

Inner rubber tube 1, the inner rubber tube 1 is made of rubber material resistant to corrosion by corrosive gases;

The inner reinforcing layer 2 comprises overlapping second warp threads 2.1 and second weft threads 2.2, wherein the second warp threads 2.1 and the second weft threads 2.2 are respectively formed by twisting at least one strand of high-strength chemical fiber.

The middle rubber hose comprises a tightly fitted inner barrier layer 3.1 and an outer barrier layer 3.2;

The mixed reinforcement layer 4 comprises a braided warp group and a braided weft group, wherein the braided warp group is composed of at least two parallel first warp threads 4.1, and the braided weft group is composed of at least two parallel first weft threads 4.2, and the first warp threads 4.1 and the first weft threads 4.2 are both twisted by at least two strands of high-strength chemical fibers;

A wear-resistant layer 5, the wear-resistant layer 5 surrounds and densely mixes the reinforcing layer 4, wherein the wear-resistant layer 5 is made of a transparent material;

1. By mixing and weaving high-strength chemical fiber and metal wire 4.3, the metal wire 4.3 increases the structural strength of the gas pipe as a whole, effectively preventing rodents such as mice from gnawing on the gas pipe, reducing safety hazards, and the gaps between the high-strength chemical fiber threads provide guidance for the accumulated gas, so that the infiltrated gas seeps out from both ends of the gas pipe;

2. An inner reinforcement layer 2 is arranged outside the inner rubber hose 1. Since the gas first seeps out from the inner rubber hose 1, it has a relatively large pressure. The inner reinforcement layer 2 made of a single material of high-strength chemical fiber weave guides the seeping gas to seep out from the end of the gas hose along the arrangement direction of the second warp 2.1 and the second weft 2.2, thereby effectively reducing the bulging phenomenon of the gas between the middle rubber layer 3 and the inner rubber layer;

3. The mixed-woven reinforcement layer 4 is provided with at least two first warps 4.1 in the warp direction and at least two first wefts 4.2 in the weft direction. Metal wires 4.3 are arranged in parallel on one side of the first warps 4.1 and the first weft 4.2 to reduce the floating gap caused by the tension difference between the metal wires 4.3 and the high-strength chemical fiber. The metal wires 4.3 squeeze the first warps 4.1 and the first weft 4.2 on the surface of the middle rubber hose to tighten the tightness of the mixed-woven reinforcement layer 4. The metal wires 4.3 are combined with the high-strength chemical fiber to ensure the structural strength and anti-twisting and anti-extrusion capabilities of the gas hose. At the same time, the intersection between the first warps 4.1, the first weft 4.2 and the metal wires 4.3 constitutes another drainage channel for the gas, ensuring that the infiltrated gas is output to both ends of the gas hose along the arrangement direction of the first warps 4.1 or the first weft 4.2, thereby effectively avoiding the accumulation of gas between the functional layers of the gas hose.

4. The braided warp group, the braided weft group and the metal wire 4.3 tighten the middle rubber layer 3, increase the compactness between the inner barrier layer 3.1 and the outer barrier layer 3.2 of the middle rubber layer 3, eliminate the adhesion and gap between the inner reinforcement layer 2 and the middle rubber layer 3, and the wear-resistant layer 5 further densifies each functional layer of the gas hose while ensuring the wear resistance of the outer surface of the gas hose, reducing the floating gap caused by the tension on the organization point of the inner reinforcement layer 2 and the mixed reinforcement layer 4;

5. The two first warps 4.1 and the two first wefts 4.2 are arranged in parallel to reduce the height difference of the organization points in the warp and weft directions. By increasing the number of parallel metal wires 4.3, the vacant area between adjacent first warps 4.1 and first wefts 4.2 is reduced, the structural tightness of the mixed reinforcement layer 4 and the degree of coverage of the mixed reinforcement layer 4 on the middle rubber hose are increased, and the overall structural strength of the gas hose is improved, and the elongation and expansion coefficient are low.

Specifically, the mixed reinforcement layer 4 is composed of a number of full cycle structures, which means that the structure points of the first warp thread 4.1 along its arrangement direction are two up and two down, the structure points of the first weft thread 4.2 along its arrangement direction are two down and two up, and the structure points of the warp metal wire 4.3 are two up and two down; optionally, the structure points of the first weft thread 4.2 along its arrangement direction are three down and three up, and the structure points of the warp metal wire 4.3 are three up and three down.

Specifically, the inner barrier layer 3.1 is a blended layer of PVC and nitrile rubber, the outer barrier layer 3.2 is a PVC material layer, and the inner reinforcement layer 2 is bonded between the inner wall of the inner barrier layer 3.1 and the outer wall of the inner rubber hose 1. By blending PVC and nitrile rubber, the tensile strength, oil resistance and gas guidance of the inner barrier layer 3.1 are increased.

Specifically, two adjacent braided warp thread groups and two adjacent braided weft thread groups are parallel to each other and have gaps therebetween. The metal wires 4.3 are arranged to fill the gaps and are staggered at the warp thread points of two adjacent first warp threads 4.1.

Specifically, the diameter ratio of the second warp 2.1 to the first warp 4.1 is 1:5, the diameter ratio of the second weft 2.2 to the first weft 4.2 is 1:5, and the diameter ratio of the connecting wire to the metal wire 4.3 is 1:4.

Specifically, the included angle between the second longitude line 2.1 and the second latitude line 2.2 is set to 60 to 90 degrees; the included angle between the first longitude line 4.1 and the first latitude line 4.2 is set to 45 to 90 degrees.

As shown in Figure 2, as an embodiment, the inner wall of the wear-resistant layer 5 is provided with a compression convex layer 5.1 corresponding to the woven warp group and the woven weft group; the outer barrier layer 3.2 is provided with a compression concave layer 3.3 corresponding to the woven warp group and the woven weft group. The compression concave layer 3.3 provides a certain installation positioning for the mixed-woven reinforcement layer 4, which is beneficial to the weaving and forming of the mixed-woven reinforcement layer 4 on the middle rubber hose. The compression convex layer 5.1 relatively compresses the mixed-woven reinforcement layer 4 on the outer wall of the middle rubber hose, which is beneficial to the wear-resistant layer 5 to compact the mixed-woven reinforcement layer 4 and ensure the structural stability of the mixed-woven reinforcement layer 4.

As an embodiment, the metal wire 4.3 has a first, a second and a third spiral position 9 along its arrangement direction. The metal wire 4.3 is located at one side of the first warp 4.1 and/or the first weft 4.2 in parallel at the first spiral position 7; the metal wire 4.3 is located between two first warp threads 4.1 and/or two first weft threads 4.2 at the second spiral position 8; the metal wire 4.3 is located at the other side of the first warp 4.1 and/or the first weft thread 4.2 in parallel at the third spiral position 9. The metal wire 4.3 is arranged at both sides of the first warp thread 4.1 and the first weft thread 4.2 in the first spiral position 7 and the third spiral position 9, so that the metal wire 4.3 tightens the first warp thread 4.1 in the warp direction and tightens the first weft thread 4.2 in the weft direction, so that the structure of the mixed-woven reinforcement layer 4 is tighter. The metal wire 4.3 presses the first warp thread 4.1 and the first weft thread 4.2 in the second spiral position 8. When the second spiral position 8 is located between two warp tissue points and two weft tissue points of the fully cyclic tissue, it can also be located at a warp tissue point or a weft tissue point.

As shown in Figure 3, as an embodiment, the first warp thread 4.1 and the first weft thread 4.2 both include a connecting thread and at least two strands of high-strength chemical fiber. The high-strength chemical fiber is wound on the connecting thread along different rotation directions, and multiple strands of high-strength chemical fiber are wound on the connecting thread 6 to form the first warp thread 4.1 and the first weft thread 4.2, thereby ensuring the structural strength of a single first warp thread 4.1 and the first weft thread 4.2. The connecting thread 6 can be made of metal or high-strength chemical fiber.
