Description

Jet former

Technical field

The present invention relates to a kind of jet former.

Background technology

Along with the kind of the design variant scheme that is used for sanitary water valve and sanitary water valve delivery port is more and more, except the cylindrical water out of known for a long time circle, the shape as the rectangular cross section of the wide flat jet that particularly has aerating or not aerating of change becomes more and more important.

Here, water valve designer's purpose is to improve the elements of modeling of sanitary water valve on the water jet that flows out water, just, water valve has, and corner angle, foursquare or rectangular geometry should be transferred on the water jet of outflow as much as possible, to realize uniform overall appearance image.

But there is such problem here usually, promptly, if should flow out transparent as far as possible jet by water valve body that is designed to rectangle or water valve outlet pipe, this jet had on foursquare or wide but flat and time sees stable profile, just do not have to rise and fall or the unexpected flow disruption that fluctuates, then can not use standardized and major part also is the standardized jet regulator of aerating or not aerating, as the jet regulator described at European standard EN246.

By DE-A-25 52 786 known a kind of devices, by this device can make the water that flows out by a spraying pack unit as far as possible low noise enter a pond.This known devices formerly has a cavity body that can be installed on the pond for this reason, and this cavity body has a fresh water inlet that is defined as being used to be connected on the spraying pack unit and exports with the fresh water that at least one passes on the pool inner wall.In order to help this reduction anti noise of known devices formerly, and in order to limit the water yield that it flows through the fresh water outlet, formerly between water inlet and described at least one fresh water outlet, be provided with such element in the cavity body of known devices by DE-A-25 52 786, the reply of this element distributes from the water of spraying pack unit and/or turns to, thereby can realize tranquilization fast and carry out the transition in the laminar flow smoothly.This distribution and/or steering component can be guide way, spigot surface and/or the screen clothes that for example correspondingly designs, these elements should not form excessive backflow (R ü ckstau) certainly, to such an extent as to form the overvoltage that causes water to eject from cavity body in cavity body.

By the known a kind of jet spraying pack unit that has shower nozzle of DE 41 08 521 A1, described shower nozzle has a plurality of water outs, sprays jet to form.Shower nozzle has a jet beam-forming arrangement that has a central water port, described central water port feed on its outside perisporium zone an annular ring around and the flow divert portion that designs pouch in, in this flow divert portion, the water jet that flows through turns to towards the relative inner shell face of nozzle housing.Particularly, also on the flow direction of flow divert portion at water jet of jet beam-forming arrangement back, form first-class rotor by this

Can avoid water to pass through water out by this circulation directly flows out.Utilize this special movement-orientedly, wish to realize that very little noise forms also realizes soft sprinkling jet.

By the formerly known a kind of jet regulator of DE 203 17 910 U1, but the housing of this jet regulator forms as the plastic injection piece that correspondingly is shaped, interfixed by two identical mirror images ground, so that be fixed on the inside of the interior cross section of a non-circular outlet.The inside of described plastic injection piece, that form a vertical surrounding on vertical side of circulation passage, be projected into the intermediate ribs in the circulation passage and form two guiding flanks that are spaced apart in the both sides of intermediate ribs.Vertically extending intermediate ribs only has slightly the portion that broadens in the central in the zone, and the guiding flank dorsad water out have the thickening part of throttle valve type equally with pointing to, described thickening part diminishes to disappearance gradually towards water out equally.Form four flow regions between the inner surface of described in front thus each flank and narrow side, each flow region is separated after with two plastic injection piece assemblings mutually, because the butt joint mutually hermetically respectively of the flank respect to one another of each plastic injection piece.Because the guiding flank is towards the face of intermediate ribs orientation and also have the inner surface of narrow side to have the distribution tendency outwards directed with respect to vertical intermediate ribs slight inclination ground, described four flow regions also tend to have at the water out place distribution tendency of outside orientation respectively.This should have such advantage, promptly, although the water jet that is formed by described four flow regions can tend to shrink immediately under action of air pressure after flowing out from the water valve of guiding water, the shape that can keep internal cross section each single flow region, that pass through outlet valve to form more longways.

By the formerly known a kind of pipeline section of US-A-2 320 530, this pipeline section can middle be connected in the sanitary pipe road.By the formerly known pipeline section of US-A-2 320 530 have one with the through-flow direction of pipeline on the contrary sprinkling can type ground to the water out of upper process.Be provided with in the inside of described pipeline section a shoehorn shape and remain on the flow divert part on week in the pipeline swingably, described flow divert part keeps the cross-section of pipeline of pipeline to expose in an one swing position, so as in its another swing position, be to make the water jet that flows through in the steering position along directional steering towards delivery port.Here the outlet of delivery port can utilize closure member sealing, link to each other with described flow divert part like this in order to make the flow divert part swing described closure member, promptly, when fetching boiling water outlet, make the flow divert part enter its steering position, and the water jet through turning to that redirect in the delivery port by pipeline can flow out on hot machine formula ground from delivery port.

Summary of the invention

So the objective of the invention is to, a kind of jet former that starts described type is provided, this jet former can form has the jet that irrespectively keeps identical and constant image appearance with the pressure oscillation in the public network of rivers as far as possible, and this jet former can also be with less expense by various flexible program manufacturings, and each described flexible program can be with separately application scenario, as filling water valve or the sink water valve is complementary in the pond on water yield stream.Here water jet should meet shape of cross section desirable and by the outlet defined on long as far as possible highway section, and can not shrink, otherwise can aware this situation in visible the rotatablely moving that visually after the jet length at several centimetres of water jet, occurs owing to the adhesion of water.

Described purpose realizes like this, promptly, jet former according to the present invention is arranged in the delivery port of outlet valve of a health and has a circulation passage that has a non-circular clean channel cross-section, vertical (length) side of the passage of this circulation passage is compared with the narrow side of passage and is designed longlyer, to form a flat jet, this circulation passage has a diversion ramp that constitutes the cross section contraction flow region on one of two vertical side of passage, this diversion ramp stretch in the subregion of circulation passage and on its steering direction towards the internal perisporium that limits circulation passage, be arranged on relative vertical side and constitute the wall section orientation of impingement area, in the circulation passage front at least one fluid rectifier is set along through-flow direction.Because diversion ramp is designed to stretch into the cross section contraction flow region in the subregion of circulation passage, so the direction deflection that the part amount of the current that flow into is continued to use the relative wall section of making impingement area.Shape-designing by described impingement area, as its gradient, arch upward and broadening with and the length of longshore current outgoing direction orientation, when leaving the sanitary outlet valve, arrive on the described impingement area and on elevational profile, be subjected to tangible influence along the water jet that this impingement area is directed.Here significant is or not the current that all flow into, but have only the part amount of described current to turn to the wall section as impingement area by diversion ramp, but described part amount can not to exert an influence by the surplus of diversion ramp guiding to current yet.The acting in conjunction of diversion ramp and impingement area and each other may with the variable relatively special orientation of the shape-designing of the condition of becoming a mandarin and water valve body or water valve outlet member and the coupling be the key factor that is used to influence the water jet that leaves outlet valve, described water jet can satisfy requirement when illustration purpose.For effect from fluid stable to the water jet that flows out that apply flow distribution, rectification and/or and for the constancy (uniformity) of the water jet that helps flowing out from impingement area, advantageously, connect at least one become a mandarin grid or similar fluid rectifier in the circulation passage front at through-flow direction

For make essential part amount can be as much as possible towards directional steering as the wall section of impingement area, advantageously, diversion ramp have one along through-flow direction towards its freely, be projected into the outline of the longitudinal edge rounding in the circulation passage.

Here, according to the of the present invention one embodiment imagination that can make especially simply, diversion ramp wood shavings shape

Protrude in the vertical side of passage.

In order to make the described grid that becomes a mandarin etc. in fact can be used as fluid rectifier, advantageously, the grid opening of at least one grid that becomes a mandarin is centered on by (langgezogen) the movement-oriented wall along the through-flow direction elongation.

Here according to form of implementation imagination of the present invention, at least one grid that becomes a mandarin roughly is arranged in the plane that is limited by one of vertical side of passage.The current that flow through the grid that becomes a mandarin etc. in this form of implementation are along the directional steering towards circulation passage, and described then water jet can be shaped in jet former in the way you want.Here according to a preferred form of implementation imagination of the present invention, the perisporium of an annular is set in the circulation passage front on through-flow direction, two vertical sides of wall of this perisporium are designed to the grid that becomes a mandarin respectively.The perisporium of this annular can abut on the interior week of outlet valve hermetically, thereby is merely able to by being arranged on the grid that becomes a mandarin at least one in the vertical side of described wall along the direction flowing water flow of jet former.

According to another form of implementation imagination of the present invention, at least one grid that becomes a mandarin is arranged in the plane of the through-flow direction orientation that is substantially transverse to circulation passage.In fact this grid that becomes a mandarin can cover the distolateral opening of the inflow side of circulation passage.

Jet former can be arranged in the outflow zone that the nothing of sanitary outlet valve turns to.Relative therewith, according to a preferred form of implementation imagination of also catering to fashion in the design of this outlet valve especially of the present invention, jet former is arranged in the turn-around zone of the directed water tumbler in a preferred approximate right angle ground.

Jet former 1,2,3 and 4 according to the present invention has a circulation passage 6, this circulation passage has a diversion ramp 11 that is designed to the cross section contraction flow region on one of vertical side of two passage, described diversion ramp on its steering direction towards around the internal perisporium of circulation passage 6, be arranged on wall section orientation on relative vertical side 8 and that be designed to impingement area 12.Because diversion ramp 11 is designed to stretch into the cross section contraction flow region in the part zone of circulation passage 6, the direction deflection that makes the part amount of the current of inflow continue to use the wall section of making impingement area 12 thus.Design model by this impingement area 12, as its gradient, arch upward and broadening (Spreizung) with and the length of longshore current outgoing direction orientation, collide on the impingement area and and when leaving the sanitary outlet valve, on elevational profile, can be subjected to tangible influence along the water jet that this impingement area is directed.Here significant is, be not the current that all flow into but have only the part amount of described current to be turned to wall section, but described part amount also exerts an influence to the not surplus by diversion ramp 11 guiding of current as impingement area 12 by diversion ramp 11.The acting in conjunction of diversion ramp 11 and impingement area 12 and mutually between also may according to the special orientation of the design change of become a mandarin condition and water valve body or water valve delivery port and to cooperate be the key factor that the water jet of outlet valve 5 is left in influence, this water jet can satisfy institute's requirement in the purpose setting.

Shown in Fig. 1,3,5,7 to 9,13 and 14, the diversion ramp 11 that protrudes in the vertical side 7 of passage here the wood shavings shape have one through-flow direction towards its freely, be projected into the outline of longitudinal edge 13 roundings (rounding) in the circulation passage 6.

Shown in Fig. 3 to 14, along through-flow direction at least one

grid

14,15 or 23 that becomes a mandarin is set in jet former 2,3 fronts, the described grid that becomes a mandarin has homogenising, tranquilization and stable effect to the outflow water jet that is formed by jet former 2,3.

In the jet former shown in Fig. 3,4,7 to 9,13 and 14 2,4, the

grid

14,23 that becomes a mandarin is designed to the member in independent and the plane that be arranged on the through-flow direction orientation that is substantially transverse to circulation passage 6, and this member connects on the distolateral opening of the inflow side that removably remains on jet former 2 by kayser.

Illustrated in Fig. 5 and 6 with respect to this form of implementation that differently designs 3, the logical direction of longshore current is provided with the perisporium 16 of an annular in the front of circulation passage 6 in this form of implementation, and two vertical sides of wall of this perisporium are designed to the grid 15 that becomes a mandarin respectively.Here also work constancy (Konstanz) and salient point the tranquilization effect of flowing, help the current that flow out from impingement area 12 near the grid 15 that becomes a mandarin that is parallel to the vertical side setting of passage of jet former 3 and also be effect flow distribution, rectification and mobile tranquilization.

By Fig. 3,4,7 to 9,13 and 14 and Fig. 5 and 6 more as can be seen, the

grid

14,15,23 that becomes a mandarin can form on jet former 2,3 or 4 or be removably fixed thereon; But a form of implementation that is not shown specifically here may be that also this grid that becomes a mandarin as fluid rectifier can be installed in the water valve body of outlet valve in the jet former front by streamwise individually.Become a mandarin grid or similarly

fluid rectifier

14,15,23 for example can have cellular or have grid-like water guide frame as shown here like that.

Fig. 1 to 6 and 9 illustrates common mode of occupation, and jet former 1,2 or 3 is arranged in the turn-around zone of water turning part of a preferred approximate right angle orientation in this case.In this zone of water turning part, the current that are conducted through the water valve body of outlet valve 5 turn to and are directed into and its delivery port 22 that roughly for example meets at right angles and be provided with.Fig. 7 with one be designed to different therewith flexible programs shown in 8, the current that flow in this scheme can not be directed with in fact turning in the zone of jet former 2, and the end regions of the outflow side of outlet valve 5 limits the flow guides that a nothing turns in this scheme.The water distribution that flows into by outlet valve 5 in Fig. 7 and 8 is extended near being parallel to the water jet that is flowed out by jet former 2.

Shown in Fig. 7 and 8 with Fig. 3 and 4 similar jet formers 2.

In order irrespectively to obtain visually identical all the time flat rectangular jet with the hydraulic pressure in the public network of rivers, particularly advantageously can be, when in the inflow side, one flow adjuster preferably is installed after the choke valve of water valve, corresponding volumetric efficiency is complementary in this flow regulator and the concrete application scenario, and described volumetric efficiency is limited in the maximum value of a time per unit of determining.Also can on its width, change the jet image of jet former by the variation of volumetric efficiency, also can be by available parallel length and speed with in the pot sink pond or the impact velocity to the object that is placed into water jet.Here particularly advantageously be that the position of the flow regulator of this and pressure correlation separates with jet former in the inflow side as far as possible far, so that made water jet homogenising as far as possible best before in the inlet that enters jet former and its export structure.

Jet former 1,2,3 and 4 frictions removably remain in the delivery port 22 of outlet valve 5 sealedly and preferably in Fig. 1-14.For this reason, be provided with joint ring 17 in the maintenance groove 16 on the periphery that is arranged on jet former 1,2,3 or 4, the preferred pressing force cooperation of sealing ring remains on jet former 1,2,3 or 4 in the delivery port 22.In order to pull down jet former 1,2,3 or 4, as for purifying reason or for outlet valve being washed, in the wall periphery that is protruding in delivery port 22 on vertical side 7 of visible side faces dorsad, process a recess 18 dorsally in the first back of installing.The tip of one screwdriver can be inserted in this recess 18, this screwdriver can be used on the outlet valve 5 jet former 1,2,3 or 4 is prized by being bearing in.

Here jet former shown in form of

implementation

1,2,3 and 4 illustrate, can be designed to sharp edge around the/edge that limits the delivery port of jet former 1,2,3 or 4, thereby described edge or seamed edge 19 work the seamed edge that drips all the time, and the water that flows out can be owing to jet former 1,2,3 or 4 adhesivenesses are undesirably moved along jet former, and may arrive the downside of outlet valve 5 by capillarity, thereby continue to flow along outlet valve 5, this is along with the time can cause inaesthetic spot.

Can see that in Fig. 9 the subregion that is positioned at lower position on outlet valve 5 of jet former perisporium also surpasses the delivery port projection of outlet valve 5, thereby water always drips on the lower limb of jet formation device and can not flow along outlet valve 5 in the outside.

Can see that by comparison diagram 1 to 14 jet former 1,2,3 or 4 that illustrates both can be used as the plastic injection piece manufacturing that also can be used as multi-piece type of single-piece here.

Also has circulation passage 6 at the jet former shown in Figure 10 to 14 4, this circulation passage has a diversion ramp 11 that is designed to the cross section contraction flow region on one of vertical side of two passage, described diversion ramp on its steering direction towards limit/around the perisporium of circulation passage 6, be arranged on wall section orientation on relative vertical side 8 and that constitute impingement area 12.Here the diversion ramp 11 that protrudes in the vertical side 7 of passage this wood shavings shape along through-flow direction towards its freely, be projected into the outline that longitudinal edge 13 in the circulation passage 6 has rounding.Can see the through flow cross section of circulation passage 6 length of comparing with the inflow side in the outflow side along the passage longitudinal direction at Figure 10 to 14.For what the inlet of circulation passage 6 inflow sides is designed to seal at end regions along the passage longitudinal direction for this reason, 23 zone lines at it of grid that become a mandarin have the cell structure of multicellular opening, different therewith, the grid 23 that becomes a mandarin seals at two end regions place along the passage longitudinal direction.The entrance of inflow side is designed to seal because circulation passage is at two end regions along the passage longitudinal direction, so the inlet sealing the subregion below form turbulent flow, described turbulent flow forms the area of low pressure 21 of side in circulation passage 6, the expansion of the water jet that this area of low pressure 21 helps flowing out and widening.In the shown jet regulator 4 of Figure 10 to 14, the water jet that flows out even on the longitudinal length of the clear opening cross section of jet former 4 outflow sides, on width, launch like this, be that this water jet keeps its width on bigger jet length, and can be shrunk to circular basically jet again.Can form wide still flat fluidics diagram picture by this way, wherein the jet that is flowed out by jet former 4 is compared and can also be flowed out on bigger jet length obviously widelyer with the jet former 1,2 or 3 that circulation passage 6 has the channel cross-section that keeps identical basically.
