【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、例えば自動車等に燃料を供給する給油所に設
置するアルコールまたはアルコール混合燃料供給用のホ
ースに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a hose for supplying alcohol or alcohol mixed fuel, which is installed, for example, at a gas station for supplying fuel to automobiles and the like.
かかる給油所では、自動車の燃料として、ガソリンや軽
油の他に、メタノールなどのアルコール類を扱うことが
考えられ、ガソリン給油機とは別にアルコールまたはア
ルコール混合燃料供給装置を設置することがある。In addition to gasoline and diesel oil, such fueling stations may handle alcohol such as methanol as fuel for automobiles, and may install an alcohol or alcohol mixed fuel supply device in addition to the gasoline refueling machine.
そして、このアルコールまたはアルコール混合燃料に使
用する供給装置のホースとして、従来はガソリン給油機
に使用しているものと同様のゴム製ホースを使用するこ
とが考えられるが、ガソリン用と同様な内面のゴム製の
ホースはアルコールのような有機溶剤など、溶解力の強
い液体を使用すると、これにより劣化したり膨潤しやす
く、寿命が短かくなる欠点がある。It is conceivable to use a rubber hose similar to that used for gasoline refueling machines as the hose for the supply device used for this alcohol or alcohol mixed fuel, but it is possible to use a rubber hose similar to that used for gasoline refueling machines. When rubber hoses are used with liquids with strong dissolving power, such as organic solvents such as alcohol, they tend to deteriorate and swell, resulting in a shortened service life.
かかる不都合を解消するには、有機化合物の影響をうけ
にくい金属製のホースを使用すればよいが、例えばワイ
ヤーブレード式の金属ホースは使用するにしたがいワイ
ヤーが切れてホース外表面にささくれが生じ、これが手
にささるおそれがあり危険であり、また、可撓性が不充
分で取扱い性がよくない。To solve this problem, it is possible to use a metal hose that is less susceptible to the effects of organic compounds; however, as wire braided metal hoses are used, the wires break and hangnails form on the outer surface of the hose. This is dangerous because it may get stuck in the hand, and the flexibility is insufficient, making it difficult to handle.
本発明の目的は前記事情を考慮してなされたもので、ア
ルコール類のような溶解力の大きい液体を使用しても劣
化することが少なく、しかも使い勝手のよいホースを提
供することにある。The object of the present invention was made in consideration of the above circumstances, and it is an object of the present invention to provide a hose that is easy to use and is less susceptible to deterioration even when a liquid with a high dissolving power such as alcohol is used.
本発明は前記目的を達成するため、可撓性金属管の外側
に補強層を設け、該補強層にゴムまたは樹脂製のカバー
を施すことを要旨とするものである。In order to achieve the above object, the present invention provides a reinforcing layer on the outside of a flexible metal tube, and covers the reinforcing layer with a cover made of rubber or resin.
本発明によれば、ホース内を流れる液体は金属内管に接
しカバーであるゴムまたは樹脂管には接しないので、液
体にアルコール類などを使用してもこれによりカバーが
侵されるおそれがない。また、ゴムまたは樹脂製カバー
と可撓性金属製内管との間には補強層が介在するので、
金属製内管をベローズのようにしても同時押出しなどの
成形時にカバー材がベローズの谷部内に入り込むおそれ
もない。According to the present invention, the liquid flowing inside the hose comes into contact with the metal inner tube and does not come into contact with the rubber or resin tube that is the cover, so even if alcohol or the like is used as the liquid, there is no risk of the cover being corroded by the liquid. In addition, since there is a reinforcing layer between the rubber or resin cover and the flexible metal inner tube,
Even if the metal inner tube is shaped like a bellows, there is no fear that the cover material will get into the troughs of the bellows during molding such as co-extrusion.
以下、図面について本発明の実施例を詳細に説明する。 Embodiments of the present invention will be described in detail below with reference to the drawings.

2図は同上要部の縦断側面図で、本発明のホース1は内
側から可撓性金属内管4、補強層3及びゴムまたは樹脂
製カバー2の3層構造により形成しである。Fig. 1 is a longitudinal sectional side view showing an embodiment of the hose of the present invention, and Fig. 2 is a longitudinal sectional side view of the main parts of the same. It has a three-layer structure including a cover 2 made of rubber or resin.
このうち、補強層3は布製あるいは合成繊維を1〜数層
に重ね合わせたものであり、可撓性金属内管4は材質と

ーズまたは蛇腹状に形成した。Among these, the reinforcing layer 3 is made of one to several layers of cloth or synthetic fibers, and the flexible metal inner tube 4 is made of stainless steel, steel, or phosphor bronze and is formed into a bellows or bellows shape. .

谷部4aにカバー材が入り込むおそれはない。In this way, to make the hose 1, the flexible metal inner tube 4 serving as the core material and the rubber or resin cover 2 are integrally co-extruded. Since the reinforcing layer 3 made of cloth or the like is interposed therebetween, even if the flexible metal inner tube 4 has a bellows structure, there is no fear that the cover material will get into the troughs 4a of the bellows due to the reinforcing layer 3 made of cloth.

とがないから、アルコールのもつ溶解力によりカバー2
が侵されることがない。As shown in FIG. 3, such a hose 1 is used, for example, as a hose for an alcohol or alcohol mixed fuel supply device 5 installed on the premises of a gas station. In this case, even if a metal tube is used as the inner tube, since it is made flexible, there is no risk that the flexibility of the hose 1 as a whole will be impaired. Since such liquids do not come into direct contact with the rubber or resin cover 2, the dissolving power of alcohol allows the cover 2 to
will not be violated.
また、前記のごとく布製の補強層3により可撓性金属内
管4にカバー材が入り込まないから、ホース1の可撓性

がおさえられ、かつ最小曲げ半径が確保される。Further, as mentioned above, since the cover material does not enter the flexible metal inner tube 4 due to the fabric reinforcing layer 3, there is no risk of the flexibility of the hose 1 being impaired, and the elongation of the hose 1 itself is suppressed. Minimum bending radius is ensured.
そして、ホース1の外層はゴムまたは樹脂製なので、内

害な液がふれたり、火災の危険性がなく、また、作業に
際して弾性のあるカバーが直接子に触れるから手触りも
よく扱いやすい。Since the outer layer of the hose 1 is made of rubber or resin, when the flexible metal inner tube 4 of the inner layer is damaged, the liquid inside is immediately and rapidly released compared to when the outer layer is made of a braid made of metal wire. Since there is no risk of overflowing and it will seep out gradually, the hose 1 can be replaced or repaired during that time and the amount of leaking liquid can be kept to a minimum, avoiding the risk of contact with liquid that is harmful to the human body or a fire hazard. It has no elasticity, and the elastic cover comes into direct contact with the child during work, making it easy to handle.
以上述べたように本発明のホースは、可撓性金属製内管

向上する。As described above, since the hose of the present invention is provided with a flexible metal inner tube, even when used for supplying liquids with high dissolving power such as alcohol, the hose will not be corroded by the liquid flowing inside. There is no risk of damage and the service life is increased.
Even when using non-electrically conductive liquids such as petroleum and chemical solvents, grounding is not required, and airtightness and heat resistance are further improved.

労破壊などを防げる。In addition, the fabric reinforcement layer maintains the flexibility of the hose, making it easy to handle, and ensuring a minimum bending radius of the hose, which prevents plastic deformation, hardening, and fatigue failure of the flexible metal inner tube. It can be prevented.
さらに、内管が破損した場合の安全性も確保されるもの
である。Furthermore, safety is ensured even if the inner tube is damaged.
