Description

  The present invention is used as a fire-fighting hose for extinguishing fires in the event of a fire, and in a disaster such as an earthquake or a typhoon, a fire-fighting hose that can be diverted as a water supply hose or a water supply hose for drinking water containing drinking water It relates to a manufacturing method.

  Generally, fire hoses used for fire fighting activities are a hose body formed by forming a lining layer on the inner peripheral surface of a jacket in which warps and wefts are woven into a cylindrical shape, and a receptacle coupling fitting attached to one end of the hose body. And a fitting fitting that is attached to the other end of the hose body and detachably joined to the receptacle fitting. Various rubber materials and synthetic resin materials are used for the lining layer of the hose body. (For example, refer to Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4) Also, various rubber packings are used for the seal packing in the receptacle fitting. (See, for example, Patent Document 5, Patent Document 6, and Patent Document 7)

  When manufacturing fire hoses, the water used in the processing of the hose body (the step of forming the lining layer into a tube or the step of closely attaching the lining layer to the inner peripheral surface of the jacket) In general, industrial water is used.

  And the storage state of the fire hose is stored and stored without being shut off from the outside air in a state where the hose body is folded flat and wound into a roll.

  By the way, fire fighting hoses use general rubber (for example, NR or SBR) as the material of the lining layer, or use general rubber (for example, NBR) for the seal packing in the receptacle fitting. If this happens, the rubber may not be compatible with the Food Sanitation Law because it contains ingredients that are inappropriate for beverages. Therefore, in an emergency such as an earthquake or typhoon, a fire hose can be used for domestic water (including drinking water). There has been a problem that it cannot be diverted as a water supply hose or a water supply hose (washing water for vegetables, fruits, dishes, bath water, washing water, etc.).

  In addition, even if the fire hose uses materials that conform to the Food Sanitation Law for the lining layer and packing material, industrial water is used in the process of processing the hose and it is in a state where it is exposed to the outside air. Because it is stored and stored, it is extremely unsanitary, and in the event of an emergency such as an earthquake or typhoon, the fire hose cannot be diverted as a water supply hose or a water supply hose for domestic water including drinking water was there.

  As mentioned above, if the fire hose stored and stored can be diverted as a water supply hose or a water supply hose for drinking water in the event of a disaster, it can be used in an emergency such as an earthquake or typhoon. However, the conventional fire hose is very unsanitary for use as a water supply hose or water supply hose, and can be used as a water supply hose or water supply hose in the event of a disaster. Development of hoses for construction is desired.

From an NBR rubber packing 2g to be inserted into the ring 2, a ring-shaped protective tire 2h to be fitted into the receptacle coupling fitting 2, and a storage bag 9 sealed with a fire hose instruction manual (not shown). It is configured.

In this fire hose, when not in use, the hose body 1 is folded in a flat shape, double-folded from the middle in the length direction, wound up in a roll shape, and a band 5 ( In this example, the band is made of polyurethane 5), and the receptacle fitting 2 and the receptacle fitting 3 are joined together to form a transparent synthetic resin film 6 that conforms to the Food Sanitation Law on the surfaces of both the fittings 2 and 3. (In this example, a polyvinylidene chloride film excellent in transparency, heat resistance, and gas barrier properties) is wound, and the hose body 1 and the two fittings 2 and 3 bound in this state are removed in accordance with the Food Sanitation Law. Put together with oxygen agent 7 in transparent multi-layer tube film 8 that has gas barrier properties that comply with the Food Sanitation Law, and store and store in a sealed state with the air in multi-layer tube film 8 replaced with nitrogen gas I have to so that.
At this time, the seal packing to be inserted into the receptacle fitting 2 is a silicon rubber packing 2f conforming to the Food Sanitation Law, and an NBR rubber packing 2g and a protection when used for fire fighting. The tire 2h is sealed together with a fire hose instruction manual (not shown) in a storage bag 9 (in this example, a transparent polyethylene storage bag 9) formed of a material harmless to the human body. Attached to the outer surface of the multilayer tube film 8 as an accessory.

A hose body 1 constituting a main part of the fire hose is formed on a jacket 1a formed by weaving a synthetic fiber warp and a synthetic fiber weft in a cylindrical shape, and on the inner peripheral surface of the jacket 1a. And a lining layer 1b made of a polyurethane resin conforming to the law.
Moreover, the structure of the jacket 1a of the hose body 1 has a cylindrical twill structure in which a number of thin polyester filament yarns are used as warp yarns so that they are difficult to get dirty and easily fall off even if they get dirty.
Furthermore, in the processing step of the hose body 1, water is used in the step of forming the lining layer 1b into a tube shape and the step of closely attaching the lining layer 1b to the inner peripheral surface of the jacket 1a. In the embodiment of the present invention, the industrial water that is generally used in these steps is not used, and the hose body 1 is processed using only tap water for water supply. Therefore, the completed hose body 1 is hygienic.

  The receptacle coupling fitting 2 and the receptacle coupling fitting 3 that are attached to both ends of the hose body 1 are both made of aluminum alloy or stainless steel that conforms to the Food Sanitation Law, and aluminum alloy that also conforms to the Food Sanitation Law. Are attached to both ends of the hose body 1 by caulking the metal rings 4 formed by the above.

That is, as shown in FIG. 2, the receptacle coupling fitting 2 is screwed into the aluminum alloy cylindrical receptacle 2a inserted into one end of the hose body 1 and the other end of the receptacle 2a. A cylindrical fastening ring 2b made of aluminum alloy, an annular pawl seat 2c made of aluminum alloy fitted in the fastening ring 2b, and an aluminum alloy made of aluminum alloy disposed at equal angles in the fastening ring 2b. It consists of a plurality of arc-shaped claws 2d, a stainless steel leaf spring 2e for urging each claw 2d inward, and a seal packing inserted into the metal fitting 2a. It is structured into a structure.
Further, when the fire hose is used as a water supply hose or a water supply hose for drinking water, the seal packing of the receptacle coupling fitting 2 uses a silicon rubber packing 2f that conforms to the Food Sanitation Law. .
The silicon rubber packing 2f is not suitable for use as a fire hose for a long period of time because of its low durability against chlorine. In order to compensate for this, assuming that the hose is used only as a fire hose, an NBR rubber packing 2g having high durability against chlorine is attached as a seal packing.

  On the other hand, as shown in FIG. 2, the insertion fitting 3 is an aluminum whose one end is inserted into the other end of the hose body 1 and whose other end is detachably inserted into the receptacle fitting 2. An alloy tubular insert 3a, an aluminum alloy push ring 3b that is slidably fitted in the axial direction on the outer peripheral surface of the insert 3a, and releases the engagement between the insert 3a and the socket coupling fitting 2. It consists of a stainless steel retaining ring 3c that is fitted to the outer peripheral surface of the metal fitting 3a and prevents the push ring 3b from coming off, and has the same structure as a conventionally known one.

  The receptacle coupling fitting 2 and the receptacle coupling fitting 3 are cylindrical metal rings in which the receptacle fitting 2a and the fitting fitting 3a are respectively inserted into both end portions of the hose body 1 and fitted to the outer peripheral surfaces of both end portions of the hose body 1. 4 is attached to both ends of the hose body 1 by caulking. Both metal rings 4 are formed of an aluminum alloy that complies with the Food Sanitation Law.

  The multilayer tube film 8 is obtained by pressing synthetic resins having different properties into one mold with separate extruders and laminating them in a tube shape within the mold. This multi-layer tube film 8 is capable of withstanding freezing and boiling of food, has gas barrier properties, is excellent in transparency and flexibility, and is made of nylon, polyethylene, and modified polyethylene using environmentally friendly materials. A general-purpose product having a three-layer structure is used.

In the fire hose described above, the hose body 1 and the like are drained before being wrapped with the transparent multilayer tube film 8 having gas barrier properties. Further, both ends of the hose body 1 are made of an aluminum alloy in which the receptacle coupling fitting 2 and the receptacle coupling fitting 3 that have been subjected to removal and cleaning of impurities including oil and fat used at the time of manufacture are also washed. The metal ring 4 is attached by caulking.
And the hose body 1 and both the fittings 2 and 3 have a temperature of 72 ° C. ± 5 ° C. which does not affect the performance of the hose immediately before being sealed in a sealed manner by the transparent multilayer tube film 8 having gas barrier properties. Under the temperature range, it is heat-dried and sterilized over 3 hours.
After that, the receptacle coupling fitting 2 and the receptacle coupling fitting 3 are joined, and conforms to the Food Sanitation Law so that the coupling fittings 2 and 3 do not damage the multilayer tube film 8 on the surfaces of the coupling fittings 2 and 3. A transparent synthetic resin film 6 (polyvinylidene chloride film) is wound.
Finally, the hose body 1, the receptacle coupling fitting 2 and the insertion coupling fitting 3 are placed in a transparent multilayer tube film 8 having a gas barrier property conforming to the food hygiene law together with an oxygen scavenger 7 conforming to the food hygiene law. Then, the multilayer tube film 8 is heat-sealed and sealed while replacing the air in the multilayer tube film 8 with nitrogen gas.

Thus, in the fire hose described above, the lining layer 1b of the hose body 1, the receptacle coupling fitting 2, the receptacle coupling fitting 3, and the silicone rubber packing in the receptacle coupling fitting 2 that are in contact with water when water is passed. By using a material that conforms to the Food Sanitation Law for all 2f, it can be used not only as a fire hose, but also as a water supply hose and a water supply hose including drinking water.
In addition, the fire hose described above is attached with a deoxidizer that conforms to the Food Sanitation Law after heat drying and sterilization so that the sanitary condition does not deteriorate during storage and storage. Since it is packaged in a sealed state with the inside air replaced with nitrogen gas by a transparent multilayer tube film 8 having a gas barrier property that complies with the law, the unused period until the package is opened at the time of use Can maintain an initial state or a sanitary state close to the initial state even for a long period of time.

  Therefore, the fire hose packaged in a hermetically sealed form is very effective for storage and storage on the beach where it is susceptible to salt damage. In addition, even if the inlet fitting 2 and the outlet fitting 3 are deteriorated or damaged due to a storage accident, etc., they have a gas barrier property used as a packaging material in periodic inspections. Since the multilayer tube film 8 and the synthetic resin film 6 are transparent, abnormalities on the surface can be easily confirmed visually.

In addition, fire fighting hoses that have been used after opening the package will leave a small amount of water in the hose body 1 and both coupling fittings 2 and 3 even after draining. Although it is highly dangerous, it is not suitable as a water supply hose or water supply hose for drinking water, but it can still be used as a fire hose.
Moreover, since this fire hose is excellent in performance as a hose, it can be diverted to applications that require pressure resistance and compact storage, such as watering and industrial use.
Furthermore, if this fire hose is used as a water supply hose or a water supply hose for domestic water including drinking water after use, if the degree of dirt is not particularly bad, it will be recovered to the manufacturer, After the manufacturer performs cleaning and quality inspection and heat-drying sterilization treatment, it can be reused by packaging the same as the first time. In particular, the jacket 1a of the hose body 1 has a cylindrical twill weave structure using a large number of thin polyester filament yarns for warp, so it is difficult to get dirty, and even if it gets dirty, it is easy to fall off. Cleaning can be performed easily and easily.

For the lining layer 1b of the fire hose, use a thermoplastic polyurethane resin that has been certified as conforming to the Food Sanitation Law. The lining layer 1b is formed from the thermoplastic polyurethane resin by extrusion using tap water as cooling water. Mold the tube.
Next, a steam heating process using tap water on the inner peripheral surface of the cylindrical jacket 1a woven in a twill structure using a large number of thin polyester filament yarns for the warp yarns and polyester filament yarns for the weft yarns. The hose body 1 is manufactured by attaching the lining tube. The hose body 1 conducts a hose inspection, passes a fire test, and passes it.
On the other hand, after removing the protective tire 2h and the NBR rubber packing 2g from the aluminum alloy receptacle coupling fitting 2 that passed the fire proof certification and received the food hygiene law conformity certification, the receptacle coupling fitting 2 is also subjected to the fire certification. Wash together with the aluminum alloy outlet fitting 3 that has passed and received the Food Sanitation Law conformity certification and drain the water. Also, the silicon rubber packing 2f that has received the certification of conformity with the Food Sanitation Law is washed and drained.
The hose body 1 is folded into a flat shape, double-folded from the vicinity of the intermediate point in the length direction, wound up into a roll, and bound and fixed with a polyurethane band 5 conforming to the Food Sanitation Law. The receptacle coupling fitting 2 and the receptacle coupling fitting 3 which have been washed and drained at both ends thereof are respectively attached by caulking a washed metal ring 4 made of an aluminum alloy conforming to the Food Sanitation Law.
Thereafter, the receptacle fitting 2 and the receptacle fitting 3 are joined, and a synthetic resin film 6 made of a transparent polyvinylidene chloride film conforming to the Food Sanitation Law is wound around the surfaces of both the fittings 2 and 3.
And just before packaging of the fire hose, the hose body 1 and both coupling fittings 2 and 3 are heat-dried and sterilized at a temperature of 72 ° C. ± 5 ° C. Attached to the hose body 1 is an oxygen scavenger 7 (trade name: Ageless (registered trademark)) that has been certified by the Food Sanitation Law. A multi-layer tube film 8 (trade name: triple nylon) is used to wrap the hose body 1, both the fittings 2 and 3, the band 5, the synthetic resin film 6, and the oxygen scavenger 7 in a sealed manner. At this time, the air in the multilayer tube film 8 is drawn out to a negative pressure, and instead, the multilayer tube film 8 is filled with nitrogen gas, and the multilayer tube film 8 is heat-sealed and packaged in a sealed manner.
Finally, a polyethylene storage bag 9 that is harmless to the human body sealed with a protective tire 2h, an NBR rubber packing 2g, and an instruction manual (not shown) is attached to the outer surface of the multilayer tube film 8.

  Thus, the fire hose packaged in a sealed manner not only fulfills the function and performance as a fire hose, but also after storage of the fire hose until it is stored and stored before use. In the meantime, it becomes a fire hose that maintains a certain quality, and can maintain a state in which it can be diverted as a water supply hose or a water supply hose for domestic use including drinking water for a long period of time.

In the above embodiment, the polyurethane resin conforming to the Food Sanitation Law is used for the lining layer 1b of the hose body 1. However, in the other embodiments, the hose body 1 EVA resin that conforms to the Food Sanitation Law may be used for the lining layer 1b.
In the above embodiment, aluminum fittings conforming to the Food Sanitation Law are used for the receptacle coupling fitting 2 and the receptacle coupling fitting 3, but in other embodiments, the receptacle coupling fitting 2 and the receptacle coupling fitting 3 are used. Stainless steel that conforms to the Food Sanitation Law may be used for the coupling fitting 2 and the insertion fitting 3.
