In order to guarantee the circulate of hot water, preferably, described hot water section 95 is shaped as cylindrical shape.
The diameter of the nozzle cooling water outlet 92 of described nozzle 9 is 3mm-10mm, preferably, is 4mm-6mm.
In addition, as shown in Figure 1, the tapering of the cold water injection of nozzle 9 outlet 16 is greater than the tapered portion 2(that is arranged on the nozzle needle end and describes in detail hereinafter) tapering.
Below describe the concrete structure of the nozzle needle of jet spool of the present utility model in detail.
As shown in Figures 4 and 5, the nozzle needle of jet spool of the present utility model comprises nozzle needle main body 1 and is arranged on the tapered portion 2 of nozzle needle main body 1 end, wherein, on the outer surface of nozzle needle main body 1, be provided with support along circumferential direction, with in the nozzle 9 that is assemblied in fluidic device at described nozzle needle the time, the outer surface of described support can coordinate or contact so that described nozzle needle main body 1 is carried out spacing with the inner chamber of nozzle 9, correspondingly, between described support, be formed with the fluid passage 3 for the fluid circulation.
The nozzle needle of this spline structure in actual use, even the pressure of the fluid by nozzle 9 more greatly or very large and flow velocity is unstable, namely along the length direction of nozzle needle, even the radial pressure that the different parts of nozzle needle bears differs greatly, also can not affect under the smooth and easy mobile prerequisite of fluid, prevent that effectively nozzle needle is because it bears very large radial pressure and depart from or radial wobble or swing occur with the spout of nozzle 9 uniformly in the radial direction, avoid having influence on the jeting effect of the nozzle cooling water outlet 92 of nozzle 9.
Effect and function according to above-mentioned described support, in practical structures, this support can have multiple different structural type, below with reference to accompanying drawing, describe several structures of described support in detail, but it will be appreciated that, described support is not limited to following described structure, and those skilled in the art can make various distortion, replacement or modification to it.
The first structure of described support:
In this structure, as shown in Figure 1, described support comprises that outer surface around described nozzle needle main body 1 is uniform and extend along the axial direction of nozzle needle a plurality of fins 4 that arrange along circumferential direction, and a plurality of fins 4 form described fluid passage 3 each other.Like this, after nozzle needle and nozzle assembling, fin 4 can contact cooperation with the inner chamber of nozzle, to the nozzle needle main body, to carry out spacing.
In reality processing, fin 4 can by the machining mode for example cutting way form, also can be by mode and nozzle needle main body 1 disposal moldings such as casting or injection mouldings, can select suitable forming method according to actual.
Further, in order to strengthen the jeting effect of nozzle, fin 4 comprises the first convex rib 41 and the second convex rib 42, wherein, with after nozzle coordinates, the first convex rib 41 can be relative with the cold water inlet of nozzle, and the radial dimension of the first convex rib 41 is less than the radial dimension of described the second convex rib 42, with the internal chamber wall with nozzle, form described fluid passage 3, with the water by the nozzle water intake, evenly import in the circulation passage 3 of nozzle needle, the outer surface of the second convex rib 42 can coordinate with the inner chamber of nozzle 9, thereby by the structural improvement of fin 4, can be when guaranteeing that support is spacing to nozzle needle, can improve the jeting effect of nozzle 9.
The length of described the first convex rib 41 depends on the axial dimension size of nozzle water intake, is generally the stroke that the length dimension of nozzle water intake on the nozzle needle axial direction added nozzle needle or nozzle.
It should be noted that, described the first convex rib 41 herein can be only one section cylindrical body, but in order to strengthen the intensity of nozzle needle main body 1, preferably, fin 4 retains the first convex rib 41.
In addition, the outside dimension of the second convex rib 42 depends on the sectional area of whole fluid passages 3, the maximum secting area that this sectional area is greater than nozzle while opening fully, and it is minimum that the hydraulic losses between the guarantee jet expansion drops to ground.
Now, nozzle needle, under the position-limiting action of support, can in nozzle, rotate, and nozzle can move with respect to nozzle needle along the axial direction of nozzle needle.The nozzle needle of this fit form and nozzle, go for having the situation of rotating component 13, and namely rotating component 13 can drive nozzle needle and rotates, and moves along the axial direction of nozzle needle thereby drive nozzle.
But in the another kind of fit form of the nozzle 9 of following explanation and the second convex rib 42, just can not be suitable for rotating component 13, namely in actual use, on the internal chamber wall of nozzle 9, can be formed with the fluting corresponding with the second convex rib 42, this fluting extends along the axial direction of nozzle 9, and the second convex rib 42 can be engaged in described fluting and slide along the axial direction of described nozzle.In this structure, described fluting has leading role and anti-rotation effect simultaneously to nozzle needle, and namely nozzle can only move back and forth along the axial direction of nozzle needle, and nozzle needle can not rotate in nozzle.During use, the position of described nozzle needle on the axial direction of described jet spool maintains static, and the end of the lifting piece that can for example be connected with the end of nozzle by external means or direct pressing nozzle, make the position of nozzle on the axial direction of described jet spool adjustable, thereby realize simultaneously described cold water is entered the adjusting of fluid space 15, hot water mouth 12a and cold water injection outlet 16.
For easily manufactured, simultaneously in order to guarantee that cold water pressure before jet expansion does not incur loss, preferably, the quantity of fin 4 is three, four or six, thereby the water cross section excessively that guarantees the fluid passage 3 that a plurality of fins form each other is greater than the cross section of jet expansion, do not incur loss to guarantee cold water pressure before jet expansion.But the quantity of fin 4 is not limited to this, also can two or five or more.
The second structure of described support:
In this structure, described support is the annular backup pad be arranged on described nozzle needle main body 1, on the plate face of this annular backup pad, forms a plurality of pod apertures as described fluid passage.
Annular backup pad can have suitable thickness according to actual needs, in addition, the shape of pod apertures is not limited to the circular hole shape, also can be fan shaped borehole, simultaneously, pod apertures should be set to the flow velocity of the fluid by it is not exerted an influence or produces slight impact, and for example, the connecting part of pod apertures and annular backup pad plate face is formed with the circular arc that is beneficial to Fluid Flow in A.
The third structure of described support:
In this structure, described support is annulus, and this annulus is connected with described nozzle needle main body 1 by a plurality of ribs, and described rib forms described fluid passage 3 each other.
The shape of annulus and rib is set to be beneficial to the smooth and easy of fluid and flows, and produces minimal effect or does not exert an influence with fluid flow.
Be only below three kinds of structural types having described support, but it is not limited to this.
In addition, as shown in Figure 4, for fear of nozzle needle with after nozzle coordinates, when the tapered portion 2 of nozzle needle coordinates with the nozzle cooling water outlet fully, the inner chamber conical surface in the support of nozzle needle and cold water injection outlet port produces interferes, preferably, between the described support of described nozzle needle main body 1 and described tapered portion 2, has the mixed water section 1a of supercharging, this supercharging mixes the cylindrical shape that is shaped as of water section 1a, with after this nozzle needle and nozzle assembling, specifically as shown in Figure 1, the mixed water section 1a of the supercharging of nozzle needle can and the internal chamber wall of nozzle between form a cold water and enter fluid space 15, can guarantee that the fluid of introducing by fluid passage mixes and realize pressurized effect in face of entering the spray cone that tapered portion 2 and nozzle cooling water outlet 92 form, and can realize pressurized effect, thereby guarantee the final good jeting effect of nozzle cooling water outlet 92 of nozzle 9.
As shown in Figure 2, when nozzle needle along the axial direction of nozzle 9 when nozzle cooling water outlet 92 moves, the tapered portion 2 of nozzle needle will coordinate with nozzle cooling water outlet 92 gradually, therefore, in order to prevent when tapered portion 2 with after nozzle cooling water outlet 92 coordinates fully, also have cold water from 92 ejections of nozzle cooling water outlet, preferably, the diameter of the mixed water section 1a of described supercharging is greater than, equals or be slightly less than the diameter of the nozzle cooling water outlet 92 of described nozzle.
After " be greater than, equal " herein referred to tapered portion 2 and nozzle cooling water outlet 92 coordinates fully, the mixed water section 1a of supercharging can seal nozzle cooling water outlet 92 fully, to prevent that cold water is from 92 ejections of nozzle cooling water outlet.
" being slightly less than " herein refers to that the diameter of the mixed water section 1a of supercharging compares with the diameter of nozzle cooling water outlet 92, both have slight difference, namely when tapered portion 2 with after nozzle cooling water outlet 92 coordinates fully, between the external peripheral surface of the mixed water section 1a of supercharging and the inner circumferential surface of nozzle cooling water outlet 92, has slight gap, although have a small amount of cold water can be by this gap from nozzle cooling water outlet 92 ejection, can ignore the minimal effect that the hot water of nozzle 9 outer walls of flowing through produces.
The length of the mixed water section 1a of described supercharging can not be too short, otherwise will likely cause nozzle water outlet bifurcated, i.e. the cross section of the length of the mixed water section 1a of supercharging and the cross section of fluid passage, jet expansion and the thickness of support are relevant, will can be very not large but affect.
