Description
Technical field
The part field of fire-fighting equipment is the utility model is related to, more particularly to a kind of fire-fighting nozzle.
Background technology
In fire-fighting domain, some fine mist spray heads are open in usual, and dust storm, insect and corrosivity pernicious gas easily pass through shower nozzle
Pipe network, valve are invaded, causes fire extinguishing system block, be corrosion-damaged, reduces its service life, in addition, system is spurting knot
Shu Hou, existing fine mist spray head will persistently drop down water, and the remaining water in pipe network is drained, and form continuous direct current waterline, cause water
Stain is lost, and such shower nozzle can not meet the use in library, while can not be used for some electrical equipment places.Secondly, some shower nozzles
In low pressure in use, atomizing effect is bad, the droplet of formation is excessive, and atomizing angle is smaller, causes zone of protection undesirable, needs to pacify
Required protected area could be covered by filling more shower nozzles, and the droplet that shower nozzle sprays in addition is distributed not in the protected area of shower nozzle
Uniformly, some places are on the high side, and other places are on the low side, directly result in protection zone protect it is unbalanced, final fire extinguishing can be influenceed
Effect.
The content of the invention
In view of the above-mentioned problems, the utility model provides a kind of fire-fighting nozzle.The technical side that the utility model is taken
Case is：A kind of fire-fighting nozzle, including knob, sprayer body, adapter, piston, sealing gasket, screen pack, hole back-up ring, spring
And sealing ring, wherein, knob is arranged on inside sprayer body, and adapter is arranged on sprayer body top, and sealing ring is arranged on adapter
Between sprayer body；Spring is arranged on inside adapter, between piston and sprayer body；Piston is arranged on inside adapter, bullet
Spring top；Piston is pressed in adapter endoporus bottom by spring；Sealing gasket is bonded in upper piston area, and hole sets adapter with back-up ring
Upper inner, screen pack are fixed in adapter upper inside wall by hole with back-up ring.
The quantity of described knob is 6, is cylinder, outer wall is provided with thread groove, is provided centrally with through hole.
Described piston lower portion is provided with 8 through holes, and top sets outside to be provided with 3 circular arc projections.
Described sprayer body is provided with 6 cylindrical grooves.
The material that described knob, piston and sprayer body uses, can be corrosion-resistant and wear-resisting for Stainless steel 316 L.
The beneficial effects of the utility model are the parts that shower nozzle of the present utility model adds similar check valve, and it can be
More than opens voluntarily under certain pressure, the seal itself in the pressure of setting, the medicament for the residual that will not be allowed in pipe network flows automatically
Out form continuous direct current waterline.The utility model devises novel turn knob part, and this knob has the helicla flute of 3 passages with
Heart small through hole, medicament is by forming strong centrifugal liquid after helicla flute, while also there is liquid discharge at center, ensures that spray orifice sprays
Atomizing effect is preferable afterwards, forms solid mist cone, in the case where sprayer body spray orifice is fixed, not only fogdrop diameter is moderate, droplet
It is evenly distributed, and atomizing angle can be increased, protected area can be effectively increased.The screen pack of shower nozzle can protect knob and spray orifice
Do not blocked by impurity, ensure that the reliability of shower nozzle action.

Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face, which combines to be specifically illustrating, is expanded on further the utility model.
Refer to the attached drawing, a kind of fire-fighting nozzle, including knob 1, sprayer body 2, adapter 3, piston 4, sealing gasket 5, mistake
Filter screen 6, hole back-up ring 7, spring 8 and sealing ring 9, wherein, knob 1 is arranged on inside sprayer body 2, and adapter 3 is arranged on shower nozzle
The top of body 2, sealing ring 9 are arranged between adapter 3 and sprayer body 2；Spring 8 is arranged on inside adapter 3, in piston 4 and spray
Between head body 2；Piston 4 is arranged on inside adapter 3, the top of spring 8；Piston 4 is pressed in the endoporus bottom of adapter 3 by spring 8；It is close
Packing 5 is bonded in the top of piston 4, and hole sets the upper inner of adapter 3 with back-up ring 7, and screen pack 6 is fixed on by hole back-up ring 7
In the upper inside wall of adapter 3.
The quantity of described knob 1 is 6, is cylinder, outer wall is provided with thread groove, is provided centrally with through hole.
The described bottom of piston 4 is provided with 8 through holes, and top sets outside to be provided with 3 circular arc projections.
Described sprayer body 2 is provided with 6 cylindrical grooves.
The material that described knob 1, piston 4 and sprayer body 2 uses, can be corrosion-resistant and wear-resisting for Stainless steel 316 L.
Operation principle：Sealing gasket 5 is bonded on piston 4, integrally formed therewith, and when shower nozzle does not work, piston 4 is by spring
8 are pressed in the one end of the endoporus of adapter 3, and now, pipe network is isolated with sprayer body and come.When fire extinguishing system starts, pipe network is put out a fire
The pressure of agent reaches certain value, and piston 4 is descending, and shower nozzle is opened, and extinguishing chemical respectively enters several knobs 1, in the work of knob
Under, the liquid flow that extinguishing chemical forms centrifugation is spilled over and is formed vaporific, and fogdrop diameter is typically in below 400um.When system is sprayed
End is put, piston 4 is up, withstands the one end of adapter endoporus, the extinguishing agent pressure remained in pipe network is extremely low, will not push up open work
Plug, avoids Liquid Residue and forms continuous direct current waterline, will not damage protected object.Before extinguishing chemical enters sprayer body 2, filtering
Net 6 need to filter out the impurity in liquid, block the spray orifice on sprayer body to prevent impurity, influence the performance of shower nozzle.
It should be noted last that above example only explains the technical solution of the utility model rather than limit to supplement
System.Although the utility model is described in detail with reference to embodiment, this area vast is it will be appreciated by the skilled person that to this
The technical scheme of utility model is modified or replaced on an equal basis, without departure from the spirit and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
