Description
Technical field
The utility model relates to a kind of spray head, is specifically related to a kind of fire-fighting spray head.
Background technology
In recent years, fire incident occurs again and again, has brought the huge person and property loss.In order to control fire in time, especially all require to arrange fire-fighting system in advance in skyscraper in public places, as hand-held fire extinguisher and prior numerous spray heads of arranging, as its name suggests, spray head is exactly when breaking out of fire, fire water is evenly spilt by spray head, thus plays an effective role in the control to the intensity of a fire of certain area.But the radiation areas of spray head of the prior art are limited, and easily there is the problem of spray head blocking, maintain cumbersome.Given this, the problems referred to above in the urgent need to address.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of fire-fighting spray head.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of fire-fighting spray head, comprise: the spray head main body and the spray head lid that form enclosed construction after assembling, described spray head lid is formed an installing hole for being fixedly connected with that with fire extinguisher canvas hose spray head main body is sent in fire water, in described spray head main body, a screen pack is set; Described spray head main body comprises sidewall and diapire, described sidewall and diapire are all formed with mouth spray, and described mouth spray is pentalpha, and the mouth spray on sidewall is at least two rows, described sidewall is also connected with several spray arms, described spray arm is formed with spray channels.So, tackled the impurity in fire water by screen pack, prevent from blocking spray head, the mouth spray of pentalpha can improve space collision and the spray dynamics of fire water, effective radiation areas increasing spray, expand spray region further by spray arm in addition.
Further, aforementioned fire extinguisher canvas hose, being provided with a booster pump near spray head lid place, solves the problem of skyscraper hydraulic pressure deficiency.
Preferably, aforementioned spray head main body is cylindrical shape, and described spray arm is 4.
Preferably, the position that aforementioned spray arm is connected with spray head main body is provided with valve, can open corresponding valve according to the actual requirements.
Further, aforementioned spray head lid is also provided with smoke sensing device and temperature inductor, dual sense and testing environment situation, guarantees to take fire protection in time.
Further, aforementioned spray channels is cylindrical through hole, and it is axially parallel with the axis of spray head main body, so, not only achieves side and bottom surface water outlet, also achieves top water outlet simultaneously, obtain better fire-fighting effect.
Usefulness of the present utility model is: a kind of fire-fighting spray head of the present utility model, the impurity in fire water has been tackled by screen pack, prevent from blocking spray head, dual-row design and space collision and the spray dynamics of fire water can be improved in the mouth spray of pentalpha, effective radiation areas increasing spray, expand spray region further by spray arm in addition, solve the problem of easy stifled, the weak effect of spray head in prior art.
Accompanying drawing explanation
Fig. 1 is the structural representation after a preferred embodiment of a kind of fire-fighting spray head of the present utility model is taken apart.
The implication of Reference numeral in figure: 1, spray head main body, 2, spray head lid, 3, screen pack, 4, fire extinguisher canvas hose, 5, mouth spray, 6, spray arm, 7, booster pump, 8, smoke sensing device, 9, temperature inductor, 10, valve.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.
See Fig. 1, a kind of fire-fighting spray head of the present utility model, comprising: the spray head main body 1 and the spray head lid 2 that form enclosed construction after assembling.Wherein, spray head lid 2 forms an installing hole, fire extinguisher canvas hose 4 is connected with installing hole, thus spray head main body 1 is sent in fire water.
In order to prevent the impurity blocking spray head in fire water, a screen pack 3 being set in spray head main body 1, correspondingly, in spray head main body 1, forming one for installing the draw-in groove of screen pack 3.
As shown in Figure 1, spray head main body 1 is preferably cylindrical shape, comprise sidewall and diapire, sidewall and diapire are all formed with mouth spray 5, in the utility model, mouth spray 5 adopts pentalpha innovatively, and the mouth spray 5 on sidewall is at least two rows (setting side by side up and down), this is because, applicant finds on stream, the mouth spray 5 of pentalpha can improve space collision and the spray dynamics of fire water, effectively increases the radiation areas of spray, to some extent solves the problem that existing spray head radiation areas are little.
In addition, sidewall is also connected with several spray arms 6,4 of preferably angularly arranging spray arm 6, and spray arm 6 is formed with spray channels, expand spray region further.Preferred as one, the position that spray arm 6 is connected with spray head main body 1 is provided with valve 10, can open corresponding valve 10 according to the actual requirements.Further, spray channels is cylindrical through hole, and it is axially parallel with the axis of spray head main body 1, so, not only achieve side and bottom surface water outlet, also achieve top water outlet simultaneously, compared to the bottom surface water outlet of existing spray head, better fire-fighting effect can be obtained.
May there is the problem of hydraulic pressure deficiency to solve skyscraper, fire extinguisher canvas hose 4 is being provided with a booster pump 7 near spray head lid 2 place.
As further improvement of the present utility model, spray head lid 2 is also provided with smoke sensing device 8 and temperature inductor 9, dual sense and testing environment situation, guarantees to take fire protection in time.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection domain of the present utility model.
