Description

Technical Field

[0001] The utility model relates to the technical field of fire hoses, and more specifically to an enhanced fireproof and flame-retardant fire hose. Background Art

[0002] Fire hose is an important tool used by firefighters to deliver high-pressure water or foam and other fire extinguishing agents during firefighting and rescue operations. It is usually composed of an inner lining, a braided layer and an outer jacket. The outer jacket structure layer of the fire-resistant and flame-retardant fire hose needs to be made of materials with this function.

[0003] One end of the fire hose is connected to a fire hydrant or a water pump on a fire truck, and the other end is connected to a water gun or other spraying equipment to form a complete water supply system. When in use, the fire pump is turned on to increase pressure, and water or fire extinguishing agents are quickly and effectively transported to the fire source for fire extinguishing operations;

[0004] In the existing fire hose (such as application number: CN202120100124.2, a high-pressure resistant fire hose), the "buffer layer 18 and the pressure-resistant layer 17 are arranged to effectively buffer the impact force brought by the water flow and avoid damage to the internal structure of the hose", but only based on the buffering properties of the materials of the "buffer layer 18 and the pressure-resistant layer 17" themselves, the impact protection between the bonding surfaces is small, which can easily lead to layer detachment.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0008] The hose body comprises an inner lining layer, a winding layer, a first adhesive layer and an outer covering layer are sequentially attached to the outer surface of the inner lining layer, and the outer covering layer is a fire retardant layer;

[0009] The first adhesive layer has elasticity and toughness after being cured.

[0010] As a preferred technical solution of the utility model, the winding layer is a polyester yarn winding layer or a cotton yarn winding layer or an aramid yarn winding layer.

[0011] As a preferred technical solution of the present utility model, the first adhesive layer is a polyurethane glue layer.

[0012] As a preferred technical solution of the utility model, a gap is left between the winding layer and the outer side of the inner lining layer for the first adhesive layer to contact the outer side of the inner lining layer.

[0013] As a preferred technical solution of the utility model, a heat insulation layer is provided between the winding layer and the outer covering layer, the heat insulation layer is bonded to the first adhesive layer, and the heat insulation layer is bonded to the outer covering layer via a second adhesive layer.

[0014] As a preferred technical solution of the utility model, the heat insulation layer is a glass fiber cloth layer or a ceramic fiber cloth layer.

[0015] The beneficial effects of the utility model are as follows:

[0016] By providing the first adhesive layer 13 between the wrapping layer 12 and the heat insulating layer 14 to provide bonding and fixing of the wrapping layer 12 and the heat insulating layer 14, after the first adhesive layer 13 is cured, under the effect of elasticity and toughness, when the impact force of the water flow in the lining layer 11 is transmitted to between the wrapping layer 12 and the heat insulating layer 14, a buffering effect can be provided, the separation of the wrapping layer 12 and the heat insulating layer 14 can be suppressed, and the connection strength can be improved;

[0017] At the same time, when the first adhesive layer 13 is disposed on the surface of the winding layer 12, the inner lining layer 11 can be contacted through the gap left between the outer side of the inner lining layer 11 and the winding layer 12, thereby further improving the connection strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a structural schematic diagram of the utility model.

[0019] Figure numerals: hose body - 1, fire-fighting buckle - 2, inner lining layer - 11, winding layer - 12, first viscose layer - 13, thermal insulation layer - 14, second viscose layer - 15, outer covering layer - 16. DETAILED DESCRIPTION Embodiment 1:

[0020] like Figure 1 As shown, this embodiment proposes: an enhanced fire-resistant and flame-retardant fire hose, comprising a hose body 1 and a fire-fighting buckle 2 fixed at the end of the hose;

[0021] The hose body 1 includes an inner lining layer 11 (the material of the inner lining layer 11 can be water pressure-resistant, wear-resistant, corrosion-resistant and non-toxic rubber, etc., to ensure the strength when conveying water under high pressure), and the outer lining layer 11 is sequentially attached with a winding layer 12, a first adhesive layer 13 and an outer covering layer 16, and the outer covering layer 16 is a fire-retardant layer (the fire-retardant layer can be made of materials such as chloroprene rubber or EPDM rubber or PVC with flame-retardant properties, providing fire-retardant, aging-resistant, wear-resistant, weather-resistant, oil-resistant, chemical-resistant and other properties);

[0022] The winding layer 12 is a polyester winding layer, a cotton winding layer, or an aramid winding layer, so as to provide sufficient tensile strength and pressure resistance and improve the structural strength.

[0023] The first adhesive layer 13 is cured to have elasticity and toughness, so as to provide bonding and fixing of the wrapping layer 12 and the outer covering layer 16. After the first adhesive layer 13 is cured, when the impact force of the water flow in the lining layer 11 is transmitted to between the wrapping layer 12 and the outer covering layer 16, a buffering effect can be provided to inhibit the separation of the wrapping layer 12 and the outer covering layer 16, thereby improving the connection strength.

[0024] The first adhesive layer 13 can be a polyurethane glue layer or the like (the polyurethane glue layer has high initial adhesion and final bonding strength, and can achieve high-strength bonding between a variety of materials (such as metal, wood, glass, plastic, rubber, fabric, etc.); it has excellent aging resistance, moisture and heat resistance, cold resistance, oil resistance, and solvent resistance, and can maintain good mechanical properties and bonding effects within a wide temperature range; the glue layer formed after curing has good elasticity and toughness, can effectively relieve and disperse stress, and is suitable for occasions that need to withstand greater impact or vibration). Embodiment 2:

[0025] like Figure 1 As shown, the difference from Example 1 is that: it also includes that a gap is left between the winding layer 12 and the outer side of the inner lining layer 11 for the first adhesive layer 13 to contact the outer side of the inner lining layer 11 (that is, when the first adhesive layer 13 is arranged on the surface of the winding layer 12, the inner lining layer 11 can be contacted through the gap left between the outer side of the inner lining layer 11 and the winding layer 12 that is bonded to it, thereby increasing the connection area and further improving the connection strength). Embodiment 3:

[0026] like Figure 1 As shown, the difference between the embodiment 1 or the embodiment 2 is that: it also includes a heat insulation layer 14 (according to the above and as Figure 1 As shown, the wrapping layer 12 is not directly bonded to the outer cover layer 16 through the first adhesive layer 13, but is bonded to the thermal insulation layer 14);

[0027] The heat insulation layer 14 is used to reduce the heat outside the outer cover layer 16 and slow down the transfer to the inner side of the heat insulation layer 14, reduce the thermal softening of the first adhesive layer 13 by the temperature, and ensure the connection strength between the winding layer 12 / the winding layer 12 and the inner lining layer 11 and the heat insulation layer 14;

[0028] Wherein, the heat insulation layer 14 is a glass fiber cloth layer or a ceramic fiber cloth layer;

[0029] The heat insulating layer 14 is bonded to the first adhesive layer 13 , and the heat insulating layer 14 is bonded to the outer covering layer 16 via a second adhesive layer 15 (the second adhesive layer 15 may also be a polyurethane adhesive layer, etc.).

[0030] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
