[Problems that this invention attempts to solve]

Conventional exposed wire laminate hoses have both inner and outer spiral rings made of stainless steel. Wire rods made of metal materials such as these were processed and used. This is about the inner spiral ring. From the viewpoint of strength to maintain the physical function as the core material of the laminated hose. The outer helical ring was designed to increase the tightening force. be.

0004 However, in the conventional exposed wire laminate hose, both the inner and outer spiral rings are fixed. Since the hose is made of metal material such as cordless, the overall weight of the hose, especially large In the case of a diameter hose, the weight of the hose increases, making it inconvenient to handle.

[0005] This device maintains a seaming force equivalent to that of a conventional outer helical ring made of metal. It is also used as a fastening material that also has anti-corrosion function, using a winding cord made of non-metallic material. This is an attempt to reduce the weight of the entire laminated hose by forming an outer spiral ring.

[0006]

[Means to solve the problem]

The basic structure of the dew wire type laminate hose according to this invention can be explained as follows with reference to Figure 1. It is a cage.

[0007] The open wire laminate hose is shown as 10, and this hose 10 is made of stainless steel. The surface An inner cloth 3 is wrapped around the inner cloth, and a continuous film 41 is spirally wound to a predetermined thickness on the surface of this inner cloth. A layered body 4 is formed, an outer cloth 5 is wrapped around the surface of this layered body, and the surface of this outer cloth is covered with a non-metallic material. The laminate is tied together at a predetermined pitch using the fastening string 2 (outer spiral string) made of material. This is an attempt to form a base.

[0008] Conceptually, the dew wire type laminated hose according to this invention is laminated with the inner spiral ring as the core. It is the same as a conventional hose in that the body is fastened by an external spiral ring, but Sealing performance between continuous films forming a laminate is improved using non-metallic, non-rigid strings. Developed materials and manufacturing methods to obtain a secure binding force and tightening method. This is the result obtained.

[0009] Although not particularly shown in the drawings, a material with the same effect as the continuous film may be provided in the laminate 4 as necessary. In some cases, a different seamless tube is installed to improve sealing performance.

0010 In addition, as a fastening string material for the outer helical ring, it has the same temperature resistance as the material forming the laminate. It has low elasticity and excellent strength, and is chemically resistant. Materials are selected and adopted.

[0011]

[Effect]

The exposed wire type hose according to this invention uses a fastening string made of non-metallic material as the outer spiral ring. As a result, the weight ratio is extremely small compared to conventional metal outer helical rings, and the entire hose It is possible to reduce the weight of the body.

【Example】

An embodiment of this invention will be described below with reference to FIG. Note that this embodiment shows a state in which the dew wire type laminate hose according to this invention is connected to a fitting. This shows the state of affairs.

[0013] As shown in FIG. 2, the laminated hose 10 according to the invention is as explained in FIG. An inner spiral ring 1 made of a metal material as a core, a laminate 4, an outer cloth 5 and an outer spiral string 2 made of a non-metal material. It consists of The above-mentioned outer spiral string 2 is of a wire rope shape based on a non-metallic thread. Therefore, if necessary, a braided cord shape can also be adopted.

[0014] As is clear from Figure 2, the hose joint has a seal securing part X and a hose gripping part Y. The seal securing part Remove the desired width L, and remove the outer spiral string 2 and outer cloth 5 by the desired width K on the outer side of the hose. It is formed in the same shape as before. Therefore, only 4 parts of the laminate are in the seal securing part X. It is considered to be exposed. In addition, the hose gripping portion Y may be specially modified depending on the shape of the laminated hose. Although it does not add any additional features, a fixing tape 9 such as adhesive tape may be applied to the surface of the outer spiral string 2. The outer spiral cord is tightened to prevent the outer spiral cord from loosening.

[0015] The above-mentioned hose securing part X and hose gripping part Y are connected to the nipple 7 and sleeve 8. The structure is such that the seal securing part The hose joint part is formed by interposing a sealing member 6 made of an elastic material such as or synthetic rubber material. has been completed.

[0016] In this embodiment, the hose gripping function is provided via the outer helical string 2 of non-metallic wire. In order to achieve this purpose, the inner helical ring 1 made of metal wire has a retaining function. In order to achieve this, a locking groove 71 that engages with the inner spiral ring 1 is formed on the nipple. Ru.

[0017]

[Effect of the idea]

This idea uses a non-metallic wire rope structure for the shape of the outer spiral string, so it is different from the conventional one. It is about 30-45% lighter than metal materials, reducing the weight of the entire laminated hose. can be reduced. An example of its use is as a fuel hose for rocket launches. Can be used in the fields of thermal flexible hoses and medical flexible hoses. It is something.

[0018] This idea can reduce the overall weight of the laminated hose, making it easier to handle. Not only is it easier, but the bending operation is also easier because the outer spiral string is made of non-metallic material. It can be done. In addition, this idea uses a wire rope structure for the outer spiral string. Therefore, you can freely select the one that suits your purpose.

[0019] In addition, the dew wire type laminated hose according to this invention only has a laminated body when joining with the coupling material. The seal securing portion formed by the seal member is sandwiched between the seal member and Since the metal inner spiral ring retains the gripping function, it has relatively low rigidity compared to metal wire. The joint portion can be constructed without applying excessive pressing force to the outer helical cord.

[0020] In addition, the dew wire type laminate hose according to this invention uses a non-metallic string for the outer spiral ring. It does not cause any damage to the ground surface, such as the deck surface of the ship's hull. In addition, the grounding function for volatile fluids is achieved by attaching a grounding wire to the outer fabric. This is no different from the conventional earthing effect.
