Description
[technical field]
The utility model relates to a kind of nozzle, relates in particular to a kind of simple in structure and not susceptible to plugging nozzle.
[technical background]
Nozzle is a kind of device for atomizing liquid commonly used in the industrial production.At present nozzle on the market has multiple version, can be divided into hollow, solid construction, taper and different structure type such as fan-shaped.
Existing conical nozzle, liquid stream angle so just has the requirement of setting height(from bottom) to nozzle about 120 degree.The control discharge orifice of conical nozzle is less in addition, stops up easily.Thereby influence the normal use of nozzle.Existing nozzle arrangements more complicated of while.
[utility model content]
The purpose of this utility model is to provide a kind of simple in structure and not susceptible to plugging nozzle.
For realizing this purpose, the utility model adopts following technical scheme:
Nozzle of the present utility model comprises: threaded joints; And be formed at end of threaded joints and diameter sprinkler head greater than the threaded joints diameter; Wherein the inner shaft of threaded joints is to offering the control discharge orifice of length less than the threaded joints axial length, further form vertically and the ponding cavity volume of controlling that discharge orifice is communicated with and defining by annular inner wall in the threaded joints towards sprinkler head, the diameter of ponding cavity volume is greater than the diameter of control discharge orifice, and the ponding cavity volume is connected by conical walls between the discharge orifice with control, and the ponding cavity volume extends to sprinkler head inside; The inside of sprinkler head forms towards the outstanding conical surface of ponding cavity volume, is communicated with and runs through the diffusion taper hole of sprinkler head outer circumferential walls on the sprinkler head along a plurality of whirl hole that are communicated with the ponding cavity volume of tangentially offering of annular inner wall and with each whirl hole; The conical surface extends to each whirl hole.
Advantage of the present utility model is: because this nozzle uses a bigger master control discharge orifice, and has a plurality of whirl hole, therefore be difficult for taking place the phenomenon of spray nozzle clogging.A plurality of slits have been offered owing on the nozzle simultaneously, therefore easily with the atomization of liquid; The utility model structure of nozzle is simple in addition, is convenient to make.

Fig. 4 is the echelon sectional view of nozzle shown in Figure 2 along the B-B direction.
[specific embodiment]
Below in conjunction with drawings and Examples the utility model is further described.
With reference to figure 1-4, the nozzle 100 that the utility model provides comprise the threaded joints 10 of cylindrical shape and be formed at end of described threaded joints 10 and diameter greater than the sprinkler head 20 of described threaded joints 10 diameters.Form abutment walls 29 between described threaded joints 10 and the described sprinkler head 20, be used to resist between threaded joints 10 and the exterior line be threaded axially get loose.
Described threaded joints 10 is used for whole nozzle 100 with the form of screw thread and other devices that liquid is provided such as fixing seals such as water pipes, so as by described nozzle 100 with the liquid jet atomization.
The inner shaft of described threaded joints 10 is to offering the control discharge orifice 12 of length less than described threaded joints 10 axial lengths.Further form the ponding cavity volume 14 that is communicated with described control discharge orifice 12 and defines by annular inner wall 142 vertically in the described threaded joints 10 towards described sprinkler head 20.The diameter of described ponding cavity volume 14 is greater than the diameter of described control discharge orifice 12, and is connected by conical walls 16 between described ponding cavity volume 14 and the control discharge orifice 12.In addition, described ponding cavity volume 14 extends to the inside of described sprinkler head 20 always.Described ponding cavity volume 14 is used for the temporary transient liquid that enters from described control discharge orifice 12 that stores.
The inside of described sprinkler head 20 forms towards the outstanding conical surface 228 of described ponding cavity volume 14, is used for the liquid in the described ponding cavity volume 14 lead (detailed aftermentioned).Be communicated with and run through the diffusion taper hole 24 of the outer circumferential walls of described sprinkler head 20 along tangentially offering of the annular inner wall 142 of described ponding cavity volume 14 is a plurality of such as 6 whirl hole that are communicated with ponding cavity volume 14 22 and with each whirl hole 22 on the described in addition sprinkler head 20.
Preferably, the described conical surface 228 extends to each whirl hole 22, so just can will be directed to each whirl hole 22 along the conical surface 228 from the flowing fluid ratio such as the water of ponding cavity volume 14 by the conical surface 228, and then helps liquid from whirl hole 22 ejections.
Further preferably, offer a plurality of on the described sprinkler head 20 such as 6 slits 26 that are communicated with described ponding cavity volume 14, by these narrow gaps 26, can increase ejection liquid pressure and reduce the ejection area of liquid, and then promote the quick atomizing of liquid.The width in described slit 26 is 0.3-0.8MM, and partially liq from then on slit 26 penetrates, and the angle of ejaculation is that the jet in a plurality of slits 26 has certain splash effect more than following 80 degree of horizontal plane, reach substantially can covering nozzles 100 belows the zone.
In the design odor removal, the swapace height of foul smell is limited, needs a kind of nozzle that can realize that the formula that drenches with rain atomizes, requires a nozzle to cover bigger area under lower setting height(from bottom), and should be solid, that is to say that the filler of nozzle below also can be covered by current.We have carried out repeatedly test in line with such principle, have invented a nozzle that utilizes principle of reflection and eddy flow principle to combine with the slit jet.
Use a cylinder stainless steel material to get final product the described nozzle of machine-shaping than minor diameter.Penetrate after liquid flows out through ponding cavity volume 14 below the conical surface 228 on, liquid is through whirl hole 22 rotation ejections then, the exit direction of this liquid stream is a horizontal direction, and certain angle of flare is arranged, the jet of 6 whirl hole 22 has intersection mutually in the horizontal plane direction.
Because this nozzle uses a bigger master control discharge orifice, and has 6 whirl hole, therefore be difficult for taking place the phenomenon of spray nozzle clogging.A plurality of slits have been offered owing on the nozzle simultaneously, therefore easily with the atomization of liquid; The utility model structure of nozzle is simple in addition, is convenient to make.
