Abstract

The invention relates to the technical field of fire fighting equipment, in particular to a fire hose and fire hose sharing system, wherein a fire hose is sleeved outside a fire hose, a fire hose throat valve controls the on-off of water flow inside the fire hose, a fire hydrant valve controls the on-off of the fire hose, an outlet of the fire hose is detachably connected with a nozzle through a first connector, and an outlet of the fire hose is detachably connected with a fire water gun through a second connector; if the fire spreads, when professional firefighters take place, the fire hydrant valve is opened, the fire hose starts to spray water, the water flow is large, and the fire can be quickly extinguished. The fire hose cover is established in the outside integrated an organic whole of fire hose, saves space greatly to when the intensity of a fire increases to fire hose uncontrollable, fire fighter need not to lay the fire hose again, improves work efficiency.

Description

Fire hose sharing system

Technical Field

The invention relates to the technical field of fire fighting equipment, in particular to a fire hose and fire hose sharing system.

Background

When a fire breaks out, timely and effective fire extinguishing is the key for reducing the fire hazard. The fire hydrant is widely applied to buildings as convenient and economical fire extinguishing equipment. The diameter of the bolt opening of the indoor fire hydrant is generally 65 mm or 50 mm, a water gun with the diameter of 16 mm or 19 mm is arranged, the water flow reaction force exceeds 220 newtons during fire extinguishing, the indoor fire hydrant is not easy to control, and the indoor fire hydrant is generally used for fire extinguishing by fire fighters or trained professionals. In order to extinguish an initial fire in time, a fire hose is often provided in a building to provide a device for ordinary persons to extinguish the fire before firefighters arrive. The diameter of the bolt opening of the fire-fighting water throat device is 25 mm, the inner diameter of the equipped fire-fighting hose is not less than 19 mm, the length of the fire-fighting hose is not more than 40 m, and the caliber of the water throat nozzle is not less than 6 mm. The fire hose can be installed in the fire hydrant box or separately. Fire hydrants and fire hoses are generally centrally located in a hydrant cabinet for ease of management.

There are two sets of systems of fire hydrant and fire hydrant in the indoor fire hydrant cabinet, therefore have the following problem: occupation space on the one hand, on the other hand, when the intensity of a fire increases to fire control water larynx uncontrollable, the fire fighter need lay the fire hose again, connect the fire branch, open the fire control valve, has increased the rescue time of putting out a fire.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, and provides a fire hose and fire hose sharing system which can save space, improve working efficiency and reduce fire-fighting and rescue time.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a fire hose shared system, including fire hydrant case and the fire-fighting lance of arranging in fire hydrant case inside, the fire hose, fire hose throat valve, the fire hydrant valve, the fire hose cover is established and is fixed in the outside of fire hose, the break-make of the inside rivers of fire hose is controlled to fire hose, the break-make of fire hose is controlled to the fire hydrant valve, the export of fire hose is through first joint detachable connections nozzle, the export of fire hose passes through second joint detachable connections fire-fighting lance.

Preferably, the outer wall of the fire hose and the inner wall of the fire hose are connected to realize fixation of the fire hose and the fire hose.

Or the first joint of the fire hose and the second joint of the fire hose are connected to realize the fixation of the first joint and the second joint.

Furthermore, the fire-fighting water throat valve and the fire hydrant valve are integrated.

Or the fire-fighting water throat valve and the fire hydrant valve are two mutually independent valves.

Has the advantages that: in the initial stage of fire, when the fire is not too large, the fire-fighting hose valve can be opened, the fire-fighting hose starts to spray water, the water flow of the fire-fighting hose is small, and even if the fire-fighting hose is not a professional fireman, ordinary personnel can operate the fire-fighting hose; if the fire spreads, when professional firefighters take place, the fire hydrant valve is opened, the fire hose starts to spray water, the water flow is large, and the fire can be quickly extinguished. This application establishes the fire hose cover in the outside integrated an organic whole of fire hose, saves space greatly to when the intensity of a fire increases to the uncontrollable time of fire hose, the fire fighter need not to lay the fire hose again, only need open the fire hydrant valve can, reduced the rescue time of putting out a fire, improve work efficiency greatly.

Detailed Description

The invention is further described below in conjunction with fig. 1-3.

The utility model provides a fire hose shared system, include fire hydrant case 10 and arrange at the inside fire-fighting lance 20 of fire hydrant case 10, fire hose 30, fire hose 40, fire hose throat valve, the fire hydrant valve, the outside at fire hose 40 is established to fire hose 30 cover, the break-make of the inside rivers of fire hose 40 of fire hose valve control, the break-make of fire hose 30 is controlled to the fire hydrant valve, the export of fire hose 40 is through first joint detachable connections nozzle 50, fire hose 30's export is through second joint detachable connections fire-fighting lance 20. In the initial stage of fire, when the fire is not too large, the fire-fighting water throat valve can be opened, the fire-fighting hose 40 starts to spray water, the water flow of the fire-fighting hose 40 is small, and even if the fire-fighting hose is not a professional fireman, ordinary personnel can operate the fire-fighting hose; if the fire spreads and professional firefighters take place, the fire hydrant valve is opened, the fire hose 30 starts to spray water, the water flow is large, and the fire can be quickly extinguished. This application establishes the outside integration an organic whole at fire hose 40 with fire hose 30 cover, saves space greatly to when the intensity of a fire increases to the uncontrollable time of fire hose larynx, the fire fighter need not to lay fire hose 30 again, only need open the fire hydrant valve can, reduced the rescue time of putting out a fire, improve work efficiency greatly.

Preferably, the connection between the outer wall of the fire hose 40 and the inner wall of the fire hose 30 realizes the fixation of the two.

Alternatively, the connection between the first connection of the fire hose 40 and the second connection of the fire hose 30 secures both.

It should be understood that the above-described specific embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Obvious variations or modifications which are within the spirit of the invention are possible within the scope of the invention.
