Description

Kink prevention hose with reinforced pressure resistance {TWISTED PREVENTION HOSE HAVING A REINFORCED INTERNAL PRESSURE}

The disclosed content prevents kinking of the hose to which the fluid is moved and supplied, and at the same time, when the fluid flows into the hose, the inner pressure is reinforced to prevent the outer diameter of the hose from being deformed by the pressure caused by the kinking. related to the hose.

Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and inclusion in this section is not an admission that it is prior art.

A hose is a pipe used as a passage for transporting a fluid such as water or gas, and various types are known. As for such a conventional hose, a synthetic resin hose made of synthetic resin and a metal hose made of metal are mainly used.

The synthetic resin hose is made of vinyl chloride, polyethylene, etc. and has the advantage of being easy to arrange and process due to its flexible material, but has the disadvantage of weak strength. It is widely used in general homes, farms, and workshops for the purpose of sprinkling.

Metal hoses are made of steel, copper alloy, aluminum alloy, etc., and have the disadvantage of not being easy to arrange and process due to the nature of the metal material, but have strong strength. It is usually used in machinery and factory facilities that flow heat, gas, and steam.

However, recently, a hose made of synthetic resin can exhibit as much strength as a hose made of metal, so a hose made of synthetic resin is most commonly used. A typical example is the pressure-resistant hose shown in FIG. 2, which is characterized in that the hose, which was conventionally manufactured only in one ply, is manufactured in a plurality of ply and a reinforcement part is provided therebetween. As such a pressure-resistant hose is manufactured from synthetic resin, flexibility is secured, which has the advantage of a synthetic resin hose, and at the same time, strength is secured as a reinforcing part is provided, so that it has the advantage of a metal hose.

On the other hand, such a conventional pressure-resistant hose is usually stored in a wound state, and in order to use it, one end of the wound pressure-resistant hose must be pulled out to sequentially unwind it. However, if a hose that has been wound in one direction for a long time is unwound while it is placed on the floor, kinking may occur. In case of kinking, the kinked parts must be manually untied, and if kinking occurs during use, the fluid flow and supply cannot be made smoothly. Therefore, to prevent such a problem from occurring, the pressure-resistant hose is wound and stored on a reel, and a separate fixing member is used to prevent the pressure-resistant hose from being twisted during use. However, in this case, it is necessary to purchase a reel or a separate fixing member, which incurs additional costs and takes a long time to work.

As a known technology to overcome this problem, the anti-twist hose (Patent Registration No. 10-1891751, hereinafter) that was filed on September 30, 2016 by the same applicant as the disclosed content and received a registration decision on August 20, 2018 referred to as prior art).

In this prior art, a reinforcing part made of weft yarn and yarn is provided between the inner skin and outer skin, and the knot of the weft yarn and the yarn is arranged in a spiral direction so that torsional stress can be applied, so that the hose in the wound state is twisted when unwinding. This can be prevented, and there is no need to purchase and use additional equipment such as a reel used for winding and unwinding the hose to prevent kinking, and a fixing member to fix the hose in use so that it is not kinked, so it has excellent economical advantages.

However, when the fluid flows into the anti-twist hose according to the prior art, there is a problem in that the overall outer diameter of the hose is increased and the overall length is reduced. As a result, when the hose is used in a state wound around the reel, the reel is damaged.

Hereinafter, the constituent members of the anti-twist hose 1 with reinforced internal pressure according to an embodiment of the disclosure will be described in detail with reference to FIGS. 1 to 3 .

First, referring to FIG. 1 , the inner skin 10 is provided. The inner skin 10 serves to flow a fluid therein and to be provided with an anti-twisting reinforcing part 20 to be described later on the outer periphery. The inner skin 10 is hollow inside so that the fluid can flow, and is formed to extend in a cylindrical shape. In addition, the molten vinyl chloride resin is manufactured by extrusion molding so as to have flexible properties capable of bending and bending.

This inner skin 10 is manufactured by the same manufacturing method as the manufacturing method of the hose according to the prior art, and since this is a known technique, further detailed description will be omitted for the sake of simplification of the specification.

On the other hand, the outer periphery of the inner skin 10 described above is provided with an anti-twist reinforcing portion (20). This anti-twisting reinforcing part 20 is made of polyester yarn, and serves to prevent the occurrence of a twisting phenomenon in the inner skin 10 and the outer skin 40 to be described later.

The anti-twisting reinforcing part 20 is arranged so that the weft yarn 21 arranged in the transverse direction and the weft yarn 22 arranged in the longitudinal direction overlap in a mesh shape. In addition, at each point where the weft yarn 21 and the yarn 22 overlap, the weft yarn 21 and the yarn 22 are woven with a knotted nose 23, and the weft yarn 21 has a knotted nose 23 of the inner skin 10. It is arranged in a spiral direction so that it can be arranged in an inclined line rather than a horizontal line with the central axis direction.

Torsional stress is applied to the anti-twist hose 1 whose inner pressure is reinforced by the knot nose 23 located in the spiral direction on the outer periphery of the inner skin 10 by the reinforcing yarn. Therefore, the twisting phenomenon can be prevented as the hose is returned to its original state in the opposite direction of the twisting by the torsional stress applied when the twisting phenomenon occurs while the hose is sequentially unwound in the winding state.

The twist prevention principle by such a reinforcing yarn is shown in detail in FIGS. 2 and 3, and it was filed on September 30, 2016 by the same applicant as the disclosed content and received a registration decision on August 20, 2018. Since it is described in more detail in the hose (Patent Registration No. 10-1891751), further detailed description will be omitted for the sake of simplicity of the specification.

On the other hand, a knitting yarn reinforcing portion 30 is provided on the outer periphery of the aforementioned twist preventing reinforcing portion 20 . This knitting yarn reinforcing part 30 is manufactured by polyester yarn like the twist preventing reinforcing part 20, and when the fluid flows in the aforementioned inner skin 10, the outer diameter of the inner skin 10 increases due to the inner pressure thereof. It also serves to prevent deformation that shortens the overall length.

Such a knitting reinforcing part 30 is provided on the entire outer periphery of the anti-twist reinforcing part 20 in a mesh shape, and through this, even if the fluid is supplied while the hose is wound on the reel, it prevents the reel from being damaged due to the deformation of the hose. can become

The outer skin 40 is fusion-fixed on the inner skin 10 provided with the anti-twisting reinforcing portion 20 and the knitting yarn reinforcing portion 30 described above. This outer skin 40 allows the positions of the anti-twisting reinforcing part 20 and the knitting yarn reinforcing portion 30 to be fixed, and the inner skin 10, the anti-twisting reinforcing portion 20 and the knitting yarn reinforcing portion 30 from external force. serves to protect. In addition, the outer skin 40 is manufactured by a molten vinyl chloride resin applied on the inner skin 10 provided with the kinking reinforcing portion 20 and the knitting yarn reinforcing portion 30 .

Such an outer skin 40 is manufactured by the same manufacturing method as the conventional hose manufacturing method, similar to the above-described inner skin 10, and further detailed description will be omitted for the sake of simplification of the specification.

The anti-twisting hose 1 with the internal pressure reinforced as described above is provided with an anti-twisting reinforcing part 20 made of a weft yarn 21 and a thread 22 between the inner skin 10 and the outer skin 40, but twisting Twisting can be prevented when the hose in the wound state is unwound by disposing the knot nose 23 of the weft yarn 21 and the yarn 22 in the spiral direction so that stress can be applied.

In addition, it is economical because it does not require the purchase and use of additional equipment, such as a reel used for winding and unwinding the hose to prevent kinking, and a fixing member for fixing the hose in use so that it is not twisted.

In addition, as a knitting yarn reinforcing part 30 for reinforcing internal pressure is further provided on the outer periphery of the twist preventing reinforcing part 20, it prevents the external shape of the hose from being deformed due to fluid flow, as well as damage to the reel due to this. This can be prevented.
