Abstract

The invention discloses a fire hose. The fire hose comprises a hose body, wherein the hose body comprises an inner water-proof layer, a wear-resistant layer wrapping the inner water-proof layer and an outmost fire-proof layer; the inner water-proof layer, the wear-resistant layer and the outmost fire-proof layer are bonded with each other; the inner water-proof layer is an elastic layer or polyurethane adhesive layer; the wear-resistant layer is woven into a net cover by a plurality of steel wires and attached to the surface of the inner water-proof layer; the fire-proof layer is woven by threads made from asbestos and is coated with vermiculite; and flanges symmetrically extend out of the side walls of the fire-proof layer and are arranged in the length direction of the hose body, and steel wires penetrate through the flanges. The fire hose is resistant to high temperatures, can resist to heat for a long time, can be conveniently folded and laid, is resistant to high pressure and wear, rapidly discharges water, has an aging service life capable of being longer than five years, and can be used for firefighting extinguishment and places with high heat, such as power stations and chemical plants (the ultimate temperature can reach 150DEG C).

Description

Fire hose

Technical field

The present invention relates to a kind of fire-fighting equipment field, particularly relate to a kind of fire hose.

Background technology

Constantly expand along with city and constantly extend with building, the ever-increasing requirement also having building industry and technology therewith, in building industry, the instrument of fire-fighting is one of most basic installation requirement, and wherein fire hose is used to transport the flexible pipe of the anti-flaming liquid such as water under high pressure or foam.Traditional fire hose is with rubber for liner, and outer surface is wrapped in Caulis et Folium Lini fabric.Advanced fire hose is then made with polymeric materials such as polyurethane.Fire hose is important equipment during fire brigade's fire extinguishing.But owing to environment different on the scene of a fire can produce unpredictable high heat, some comburant can produce higher cigarette, gas, radiant heat, thus causing that fire hose is damaged.In prior art, fire hose normally uses temperature below 70 DEG C, extremely heat-resisting below 110 DEG C, uses scope and sphere to be restricted.

Summary of the invention

It is an object of the invention to the deficiency overcome in background technology, it is provided that a kind of fire hose that can solve the problems referred to above.

The concrete technical scheme of a kind of fire hose of the present invention is: include belt body, described belt body includes the inner waterproofing layer being mutually bonded, the wearing layer wrapping up inner waterproofing layer and outermost fireprotection layer, and described inner waterproofing layer is containing following weight percent composition and content: PVC/NBR blend composition 56%；Dioctyl phthalate 5.7%；White carbon 17.3%；Plasticizer TP-90B8.2%；Binding agent 3.8%；Titanium dioxide 0.7%；Paraffin 0.8%；Activator 2.5%；Accelerator 1.0%；Age resistor 1.0%；Elastic layer that sulfur 1.2% is made or polyurethane sebific duct, described wearing layer is become net attachment inner waterproofing layer surface by some braided steel wires, and the silk thread that fireprotection layer is made up of asbestos weaves and is coated with Vermiculitum and constitutes, and fireprotection layer sidewall symmetry extends outward the flange arranged along tape body length direction, run through in flange and be provided with steel wire.

Further, the thickness of described inner waterproofing layer, wearing layer and fireprotection layer is than for 2:1:1.

Compared with prior art, it is an advantage of the current invention that: heat resisting temperature height, heat-resistant time length, collapsible, to lay convenience, pressure height, water outlet fast, wear-resistant, aging life-span was up to more than 5 years, can be used for fire-fighting fire extinguishing, the place (limiting temperature is up to 150 DEG C) that the heat such as power station, chemical plant is higher.

Accompanying drawing explanation

Fig. 1 is the structural representation of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, the invention will be further described.

Consult Fig. 1, the concrete technical scheme of a kind of fire hose is: include belt body, described belt body includes the inner waterproofing layer 1 being mutually bonded, the wearing layer 2 wrapping up inner waterproofing layer 1 and outermost fireprotection layer 3, and described inner waterproofing layer 1 is containing following weight percent composition and content: PVC/NBR blend composition 56%；Dioctyl phthalate 5.7%；White carbon 17.3%；Plasticizer TP-90B8.2%；Binding agent 3.8%；Titanium dioxide 0.7%；Paraffin 0.8%；Activator 2.5%；Accelerator 1.0%；Age resistor 1.0%；Sulfur 1.2% elastic layer or polyurethane sebific duct, described wearing layer 2 is become net attachment inner waterproofing layer surface by some braided steel wires, and the silk thread that fireprotection layer 3 is made up of asbestos weave and be coated with Vermiculitum solution cured after constitute, and fireprotection layer 3 sidewall symmetry extends outward the flange 31 arranged along tape body length direction, run through in flange 31 and be provided with steel wire 32.

Further, the thickness of described inner waterproofing layer 1, wearing layer 2 and fireprotection layer 3 is than for 2:1:1.

The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, all in like manner include in the scope of patent protection of the present invention.
