Abstract
The utility model discloses a high-pressure tiny-water atomizing jet, comprising a jet foundation, a filter screen support and a jet body, wherein a filter screen is sleeved in the external of the filter screen support, and a rotation core is installed inside the jet body. The high-pressure water above 8 M P a which enters from the jet foundation is separated in a big-end surface groove of the filter support, then is filtered by a filter screen from the backlash of the jet foundation and the filter screen support and then reach the jet body. And then the high-pressure and high-speed water flow is rotated by a rotation core installed inside the jet body, consequently the turbulent current intensity is increased. After being completely mixed in a mixing cavity of the jet body, the water is projected from a tiny spraying opening. The tiny-water atomizing jet can enable the water to be highly turbulent-flowed and rotated before being projected, and the ejected water is sucked, broken and atomized by the outside air, consequently the high-speed homogenous tiny-water fog with the diameter less than 100 micrometers is produced and the atomizing effect is perfect. The utility model is not only adaptable for fire-extinguishing, but also adaptable for other industrial fields, such as pesticide sprinkling, food manufacturing and the like.
Description
Technical field
The utility model relates to a kind of heavy pressure fine spray nozzle, particularly relates to a kind of nozzle that is applicable to fire extinguishing.
Background technology
In fire-fighting fire extinguishing, generally all adopt water sprinkler system.The non-fire damage of water sprinkler system is that water stain harm is very big.Up-to-date in the world scientific research at present shows: fine water mist fire-extinguishing system can put out category-A, category-B, C class, D class and electrical fire, and range of application is extremely wide, and non-fire damage is minimum, and water consumption is few.Fine water mist fire-extinguishing system now become in the world praise highly atmospheric ozone layer is had the HALON fire extinguishing system substitute of destruction.
In the fine water mist fire-extinguishing system commonly used at present, all adopt the gas-liquid two-phase atomizer, its atomizing effect is because the tearing of auxiliary gases at high pressure, fragmentation are fairly good, but its shortcoming is to need to be equipped with in addition auxiliary gas cylinder and associated conduit facility, system complex, it is big to take up room.
Summary of the invention
The utility model provides a kind of can remove the high pressure gas auxiliary equipment, compact conformation to current heavy pressure fine spray nozzle.
The technical solution adopted in the utility model is: it comprises nozzle base, is with the nozzle body that the screen holder of filter screen, interior dress revolve core outward.One end of nozzle base has the screwed hole that is connected with spray gun, the other end has the screwed hole that is connected with the nozzle body rear end, the centre of nozzle base has runner, the small end that is contained in the screen holder in the nozzle base runner and nozzle body are with being threaded, have waist shape runner on the screen holder, runner in waist shape runner on the screen holder and the nozzle base is communicated with, and is equipped with in the hybrid chamber of nozzle body and revolves core, and the front end of nozzle body has the spray orifice that is communicated with hybrid chamber.
For the ease of the shunting of current direction both sides, have groove at the screen holder large end face.
Shunt in the groove of screen holder large end face by the water under high pressure that nozzle base enters, through strainer filtering, enter waist shape runner on the screen holder until nozzle body by the space between nozzle base and the screen holder greater than 8MPa.Make the rotation of high-voltage high-speed current by the core aperture that revolves that is provided with in the nozzle body again, strengthen its turbulence intensity, after in the hybrid chamber of nozzle body, fully mixing, by tiny spray orifice ejection.This mist-generating nozzle make water before delivery nozzle not just by highly turbulent flow, rotation, fully entrainment with extraneous air the ejection back, broken, atomizing, can produce diameter less than all even and fine water smoke of the high speed of 100 μ m.
The beneficial effect that the utlity model has:
1) revolving property and the turbulence intensity of nozzle interior structure energy reinforced high pressure current, outlet promptly produces the thin water smoke of high-speed and high-density, realizes effectively putting out a fire rapidly;
2) atomizing effect is good, fogdrop diameter little (SMD≤100 μ m);
3) water consumption is few, compares water spray and other direct-injection type mist-generating nozzle, its capacity usage ratio height, and water damage is little;
The utility model not only is used for fire-fighting fire extinguishing, also can be used for other industrial circle, as pesticide spraying, food processing etc.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1 nozzle base, 2 screen holders, 3 filter screens, 4 nozzle bodies, 5 revolve waist shape runner, 9 hybrid chambers, 10 spray orifices on core, 6 runners, 7 grooves, 8 screen holders.
The specific embodiment
As shown in drawings, the utility model comprises: base 1 is outer to be with the nozzle body 4 that the screen holder 2 of filter screen 3, interior dress revolve core 5 and to form.Between the nozzle base 1 of mist-generating nozzle and nozzle body 4, a runner 6 is arranged, in the middle of runner 6, be provided with screen holder 2 and filter screens 3.Have passage can pass through current between screen holder 2 and the runner 6, the groove 7 that screen holder 2 large end faces have is convenient to the shunting of current direction both sides.Current are after filter screen 3 filters by the waist shape runner 8 on the screen holder 2, and through revolving the aperture rotation on the core 5, turbulence level increases, and mix through nozzle body 4 inner mixing chambers 9 again, and by elongated spray orifice 10 ejections, current are promptly once sheared atomizing by outside air in outlet.Simultaneously, the current of ejection also have very strong revolving property, can constantly entrainment a large amount of air in the process of advancing at utmost speed, and form secondary-atomizing and repeatedly atomizing, finally reach good atomizing effect.In establish screen holder 2 and filter screen 3, can prevent that the tiny spray orifice 10 of nozzle body front end from stopping up.
