Description
Technical field
The present invention relates to a kind of control system, described control system has at least two passage guide part and the intermediate plate being arranged between two passage guide parts.Described intermediate plate includes the smooth metal liner layers of at least two and is arranged in the filter mesh layer between at least two surface metal laying.In intermediate plate, forming one or more fluid passage openings, this fluid passage openings is by smooth metal liner layers, thus they form passage opening.These passage openings are crossed over by filter mesh layer.Described filter mesh layer is mainly used as filter to catch granule, and this granule is likely to be not carried in passage guide part, and therefore they are likely to cause obstruction and functional fault at that.Filter mesh layer is not intended to removable filter system, but is the long-term element installed, and it is used in the whole system except another filter system that can be replaced and empty.This control system is particularly used in the control system in hydraulic drive, particularly vehicle.
Background technology
Including there is the control system of intermediate plate of filter screen (screen) generally from known in the state of the art.In EP0803654A2, disclosing a kind of control system, the intermediate plate of this control system includes bearing part and screen material.Being securely connected to bearing part at that this screen material in a continuous manner via elastic lip, described elastic lip is turned over lining (curedinplace) and so continuously around the single opening of bearing part.But, this relates to the sizable effort in manufacture.Additionally, practice display, by current pressure given in Hydraulic Power Transmission System, the structure with elastic lip and only one loading plate can not with secure manner sealing control system chronically.
Deviate from EP0803654A2, DE102007019946 and improve the former solution, because metallic plate laying is arranged on two surfaces of continuous filtering stratum reticulare by it.Instead of and in EP0803654A2, filter screen is connected to bearing bed and is used simultaneously as the elastic lip of containment member, employ two different kinds of potted component at this.On the other hand, the region not being used to fluid passage is filled with sealing block, in order to avoid transverse leakage.On the other hand, it is directed away from those surfaces of filter mesh layer to be provided with extra elastic packing lip at metallic plate laying.So, the manufacture work compared to EP0803654A2 is further augmented.
DE202010006768U1 greatly simplify sealing idea.Simultaneously, practice have shown that in the relatively large passage opening in metallic plate laying, when being exposed to only in one direction by the strong impulses pressure of filter screen or be exposed in the two directions by filter screen but when there is the fluid of significantly different pressure in the two directions, the screen area being subject to the impact of these liquid stream stretches on path direction, the open area of such filter screen is strengthened in passage opening, and consequently, it is not possible to as required for catch all granules.Due to filter mesh layer extremely stretching in the region of passage opening, such danger occurs: the single filament thread breakage of filter screen.In the worst case, this filter screen is not only no longer able to catch granule, and is the pollution granule in fluid line from the wire section circulation of the fragmentation of filter screen itself.
Summary of the invention
Therefore, it is an object of the invention to provide a kind of control system, the intermediate plate of described control system provides good sealing characteristics and at least one steady in a long-term and dimensionally stable filtration zone.Additionally, control system is for making by few cost.
The solution of this purpose is to be realized by control system according to claim 1.Preferred embodiment describe in the dependent claims.
Therefore, the present invention relates to a kind of control system, described control system has at least two passage guide part and the intermediate plate being arranged between said two passage guide part.Described intermediate plate includes the smooth metal sealing layer of at least two and the filter mesh layer between two smooth metal sealing layer.Smooth sealant (in order to distinguish with filter mesh layer better) is continuous print layer outside being construed as removing passage opening, is therefore sheet-metal layers especially.Described control system includes the multiple passage openings for fastening component, the plurality of passage opening is by all layers of described at least two passage guide part and described intermediate plate, simultaneously, described intermediate plate includes at least one fluid passage openings, at least one fluid passage openings described is by the smooth metal sealing layer of described at least two, and described filter mesh layer crosses at least one fluid passage openings described.Fluid passage openings is understood to such region, its in each of two passage guide parts of adjacent intermediate plate individually to being open to outward single opening or outwardly open in single passage.In order to ensure the filtration zone durable for a long time even with huge and unilateral pressure loading, at least one for described filter mesh layer supports at least one arranging the fluid passage openings formed in the described smooth metal sealing layer being adjacent to described filter mesh layer.
Described support arranges the extension consistently formed as extending in the fluid passage openings in the smooth metal sealing layer being adjacent to described filter mesh layer.Support layout can extend in fluid passage openings simply or be formed as connecting two edges of fluid passage openings and by the bridge of the fluid passage openings segmentation in each smooth metal sealing layer.At least one extension is formed without independent parts or the parts independently formed, but from each smooth metal sealing layer or its continuous edge and therefore become single type with each smooth metal sealing layer.
When opening the fluid passage in region of sealant and being cut by bridge and be divided into two parts, if it is continuous both down and up with single passage, then it is never considered single fluid passage openings.It is enough even at the one-sided continuity in only one passage, in order to be considered as being divided into by this way the fluid passage openings of single fluid passage openings.
In the first embodiment, this at least one fluid passage openings is formed as fillet convex polygon, and described fillet convex polygon includes polygonal n angle.Fillet convex polygon is understood by this way, due to when by punched openings in sheet-metal layers, it is often necessary to utilize the flat-rammer of transverse circular to carry out work, therefore the angle of convex polygon is circular to realize the acceptable utility services time.This also result in the fillet in parts.Commonly used radius is between 0.3mm and 1mm in this respect.Therefore, the wedge angle that polygonal n angle is not actual, but it is understood to be virtual angle, which results in when being left out rounding, make the intersection point of polygonal side continuous print line.This is equally effective for another polygon fluid passage openings, and this will mention in following several sections.
At the fluid passage openings place of the convex polygon of this first embodiment, at least one support described is arranged and is formed at least one the smooth metal sealing layer being adjacent to filter mesh layer.Described at least one support and arrange and be preferably formed to edge from fluid passage openings or two different edge edges are stretched out stretches out bridge, described edge part is spaced apart from each other.Stretching out bridge by polygon segmentation and to intersect with polygonal at least one diagonal, described diagonal connects described polygonal two angles.Polygonal limit number is more many, and therefore polygon has the angle of greater number, it is preferred that polygonal two angles are not lucky adjacent angular.It is preferred that both, when polygon has n angle of even number, said two angle is spaced apart from each other described polygonal n/2 angle, and when polygon has n angle of odd number, and said two angle is spaced apart from each other described polygonal n/2+1/2 angle.As such, it is possible to it is well established that the filter mesh layer that described vicinity given by described bridge provides good support.
Although bridge being called the most cases arranged that supports of primitive form uses the term " bridge " said the meaning of the element connecting two edges, but term also including from meaning that it has " bridge " said the meaning of " bridge of boats " of a free end.The other end is the extension of the single type that the edge from fluid passage openings stretches out.
It particularly preferably is, if at least one supports at least one bridge arranged and not only crosses over polygonal such diagonal, and described polygonal the plurality of cornerwise minimal number, this minimal number is derived from rounding up of n/3 (if n is odd number) and n/6 (if n being even number).This difference is derived from two diagonal (wherein, n is even number) met in pairs.
If n trends towards infinity, then term " fillet convex polygon " also includes the circle as extreme shape.Preferably support layout as what be used for filter mesh layer in the region of circular flow passage opening, therefore can use such bridge: described bridge connects two edges of the circular flow passage opening in the smooth metal sealing layer being adjacent to filter mesh layer.Position for bridge, it may be considered that difform bridge.On the other hand, these are the shape of bridge: the shape of described bridge has its width in its route and changes, and the described change factor is 2 to the maximum.At this, the contiguous transition point between bridge and reality circle is spaced apart from each other 120 ° of round circumference.On the other hand, these are the shape of bridge: the shape of described bridge has the change of its width in its route, and the described change factor is more than 2, and therefore the shape of described bridge broadens its exterior domain especially, therefore close to the circle being transitioned into reality in it.At this, if the contiguous transition point between the actual circle at two edges of bridge and a bridge is spaced apart from each other at least 90 °, then this is enough.
If also contemplating such line except aforesaid transition point, at this this bridge of line place, there is the half of its width and this Qiao Gai center or center line to intersect with the imagined extension (continuation) of the circumference of circle, the two point of (change of width is up to 2) is spaced apart from each other at least 150 ° of round circumference then in the previous case, and the two point of (change of width is more than 2) is spaced apart from each other at least 120 ° of round circumference in the case of the latter.
By the ellipse of the extreme shape as fillet convex polygon, as the shape of fluid passage openings, produce comparable situation.
But, if at least one fluid passage openings is fillet concave polygon, therefore, if if at least one edged surface polygonal is inside and this polygon shows at least one contraction flow region (constriction), then described support is arranged and is preferably formed to the bridge that the edge from fluid passage openings stretches out, the more described contraction flow region of described spanning and split fluid passage openings by this way.Again, this at least one support is arranged and is formed in the smooth metal sealing layer of adjacent filter mesh layer.
By the fluid passage openings elongated, certainly it is also possible that arrange more than one bridge and arrange as the support of described fluid passage openings.By the fluid passage openings of convex polygon, multiple bridges are advantageously arranged by this way, before equally effective now for the region extended between multiple bridges by multiple bridges of layout, the non-just adjacent bridge of the plurality of bridge but be spaced apart from each other a bridge or the bridge between the edge of fluid passage openings and next bridge.At this, independent bridge is arranged close to each other and different from each other on its main bearing of trend reaches at most 45 °.By the fluid passage openings of concave polygon, in the region of contraction flow region as described in being preferably formed in Long Circle fluid passage openings or in multiple angled fluid passage openings (in the fluid passage openings in the concave polygon having been described above).
If the extension that the edge of the fluid passage openings that the described support being used for filter mesh layer is arranged as from the one of smooth metal seal areas extends, then another embodiment of the present invention result is almost circular fluid passage openings.At least one extension described in described smooth metal seal areas from virtual continuous circumference circle (circumferentialcircle) extend to by virtual continuous circumference circle around region reach fluid passage openings circular diameter maximum 1/3.
This embodiment arranged that supports in control system according to the present invention includes two to eight extensions.Single described extension is spaced apart from each other.Especially, at least 15 ° of the circumference of the spaced apart virtual continuous circumference circle of single described extension, it is preferable that at least 20 °.But, at least the 1/3 of the circumference of virtual continuous circumference circle preferably not only exists virtually, and exist as actual circumference circle, described at least the 1/3 of described circumference is slit into multiple part by described extension as a rule and defines actual virtual continuous circle.
Independent of the basic configuration of fluid passage openings, provide described support component for the one in the described multiple embodiments supporting layout of filter mesh layer and include the extension that the edge of the fluid passage openings from the smooth metal sealing layer of adjacent described filter mesh layer extends.Compared to the described path surface of the fluid passage openings without described extension, described extension will abut against the path surface of the described fluid passage openings in the described smooth metal sealing layer of described filter mesh layer and decreases 5% to 20%.If the path surface that the extension by the path surface of the continuous path opening on the opposite side of filter mesh layer compared on the side of filter mesh layer reduces, then this minimizing can also by measuring compared with the fluid passage openings in filter mesh layer is relative smooth metal sealing layer.
Generally speaking, if at least one fluid passage openings at least one of smooth metal sealing layer by least one containment member around, then control system is advantageous for.Preferably, described containment member is arranged in the one in the described smooth metal sealing layer of adjacent described filter mesh layer.If if described containment member is arranged in the smooth metal sealing layer of adjacent described filter mesh layer or includes described containment member towards two sealants of passage guide part, then creating another and improve.If the fluid passage openings in the one of the passage guide part of adjacent described intermediate plate not outwardly open in opening but outwardly open in passage or in a part for passage, when the length extended in described fluid passage openings interface between intermediate plate and passage guide part is more than four times of its width, if then formed smooth metal sealing layer towards the containment member on the side of passage guide part not only in a continuous manner around access portal, but also continuously around the passage in contiguous passage guide part or channel part, then it is advantageous for.
If containment member is the welding bead (bead) formed in the one of smooth metal sealing layer, then it is advantageous for.Described welding bead can be implemented with the whole welding bead in substantially U-shaped or barrel-shaped cross section or is embodied as half welding bead with substantially flat z shape cross section.If described welding bead is formed as being extended with the complicated welding bead system of fork and lateral road (crossing) in the layer of smooth metal sealing layer, then it is preferred.In fork and lateral road region, can gradually becoming half welding bead after whole welding bead, vice versa.Especially towards the outward flange of intermediate plate, complicated welding bead system is Guan Bi, it means that seals spaced apart with the outward flange of described intermediate plate and along described intermediate plate the outward flange of line and extends.Preferably, complicated welding bead system is additionally included in the part in self-contained (self-contained) inner region of described intermediate plate.These regions are such region particularly: described region is around passage opening and be from passage opening continuous print channel part in a continuous manner as a rule.
As alternative or supplementing as the former, containment member can be the coating based on polymer, and described coating is particularly partially applied to certain pattern at least one surface of at least one of smooth metal seal areas.Same at this, coating patterns is preferably the complex pattern with fork and lateral road and also including except line self-contained around outward flange at a certain distance and is similarly self-contained and around the other part of passage opening (and as a rule from these passage opening continuous print channel parts).In the first modification, therefore partial coating is unique containment member.In the second modification, the welding bead system of welding bead or complexity is at least covered by the coating at least in part in the one on its surface.In this respect, if coating reaches on the transverse edge in actual welding bead region, such as reach from both sides about or accurately half weld width or whole weld width, then this is advantageous for.Generally, if the one of the smooth metal sealing layer of adjacent filter mesh layer includes such multiple part, in the plurality of part, cladding or uncoated welding bead are formed in these sections as containment member, and the partial coating that the plurality of part additionally includes wherein on one or two surface represents multiple parts of the unique containment member in those parts, then this is also feasible.
Except containment member (it also will be referred to as active layer (activelayer) hereinafter) that is that have welding bead and/or that be coated with, intermediate plate can also include an extra sealant, described extra sealant except passage opening do not include any structure and itself or do not include coating or at least one on its multiple surfaces, be substantially completely coated with the coating based on polymer, the coating of this polymer-matrix is similar to the partial coating of one or more active layer or has the coating (such as, zinc-plated) of Metal Substrate." substantially completely " can be interpreted as by this way within this context, the edge of passage opening can (but need not) be not coated with, or this coating removes from these edges of passage opening, thus in operation, the granule of coating is not released, and then the granule of described coating is likely to be formed the additional load of the filter screen part for described intermediate plate.This non-structured additional sealing layer is commonly referred to as wall (distancelayer), and this is because one of its task is to make the whole of described intermediate plate be highly adaptable to installation situation.Especially for the active layer having welding bead, its separation sealing line being additionally operable to either directly or indirectly arrange active layer in its surface, because it generally includes enough thickness and hardness is come bend resistance.Hereinafter, this non-structured sealant is also referred to as wall.
For partial coating, it is preferably used following coating material: described coating material includes FKM (Viton, such as vinylidene fluoride-hexafluoropropylene copolymer), silicone rubber or itrile group butadiene (NBR) rubber (nitrile rubber), hydrogenated nitrile-butadiene rubber (HNBR) (hydrated nitrile rubbers), PUR (polyurethane), NR (natural rubber), FFKM (FFKM) (perfluor-elastomer), butadiene-styrene rubber (SBR) (butadiene-styrene rubber), BR (butyl rubber), FVSQ (fluosilicic rubber), CSM (chlorosulfonated polyethylene), the mixture of silicones and/or epoxy resin or above-mentioned substance.The scope of preferred coating layer thickness is between 15 μm and 60 μm, especially between 20 μm and 40 μm.
In another embodiment, the coating of the polymer-matrix of part coating is foam coating, and described foam coating is characterised by extra high elasticity and can adapt in various shape.If these foam coatings are based on NBR or FKM, then it is preferred.
Only in when few, in all fluid passage openings, show only relative, second surface from the first surface of intermediate plate to intermediate plate or only from first passage guide part to the fluid stream of second channel guide part according to the control system of the present invention.But as a rule, they include following two fluid passage openings: provide the fluid passage openings passed through from first surface to second surface for fluid stream；For this fluid by and fluid flow to the fluid passage openings of first surface of intermediate plate from the second surface of intermediate plate.In this case, intermediate plate includes at least two fluid passage openings, each in two fluid passage openings includes supporting arranges, two of which supports layout and is embodied as different smooth metal sealing layer, different smooth metal sealing layer boths is adjacent to filter mesh layer, but from relative surface contiguous filter mesh layer.Therefore, intermediate plate includes arranging at least one support of filter mesh layer part, and wherein fluid leads to second surface from first surface, wherein supports and arranges that realization is in the smooth metal sealing layer of adjacent filter mesh layer and the second surface pointing to intermediate plate.This at least one preferred embodiment including the another part for filter mesh layer supports arranges, in this another part, fluid flows to first surface from the second surface of filter mesh layer；At this, support layout and correspondingly realize in the smooth metal sealing layer of adjacent filter mesh layer and the first surface pointing to intermediate plate.
Furthermore, it is possible to there is fluid passage openings, wherein depend on that the fluid of operation and switch instances flows up in a direction and the opposing party.Especially, if fluid stream at least one direction realizes with high pressure, then can be advantageous in following modification: in this modification, if the both sides of the filter mesh layer in the smooth metal sealing layer that each is contiguous being provided with support layout, particularly bridge shape support layout.The projection that this two (particularly bridge shape) supports in the plane being arranged into filter mesh layer is overlapping at least in part, thus liquid stream cross section is only only reduced to acceptable degree by them.If they whole regions are overlapping, then it is preferred, thus independent of flow direction, providing the excellent support to filter screen without the cross section reducing liquid stream further.
Filter mesh layer is preferably made up of grid material.Grid material in meaning of the present invention not only includes the fabric of knitted fabric, stitch bonded fabrics, rove or crochet, is also textile material especially.Within this context, plane or twill-weave are preferred.Except untreated textile material, it is also possible to use the textile material having been at being compressed.In the textile material of compression, it is especially preferred, because they easily manufacture that press polish processes textile material.The compression of grid material or press polish process the thickness causing material reduction on the direction of plane being perpendicular to screen material.By this compression, the thickness of the grid material of filter mesh layer can reduce 25% to 70% relative to its original thickness, it is preferable that reduces 35% to 55%.After compression, the thickness of silk thread on the bearing of trend that it is the shortest must at least 30 μm to avoid the destruction (such as, fracture) of grid material.Therefore the thickness of silk thread is more big is preferred, for instance about 55 μm to 150 μm and be 70 μm to 90 μm especially.As alternative, filter mesh layer can also be made up of smooth material, and this smooth material is such as by etching or being set porose by stretching this material (about characteristic steel).The scope of the diameter in hole is from 120 μm to 200 μm, it is preferable that from 120 μm to 150 μm.The distance in hole selects especially by this way, thus produce >=and the open area of 30%, preferably >=35%.
If filter mesh layer includes textile material, then this textile material show preferably the mesh width between 100 μm to 250 μm.For pressure drop and the size of granule that retains in filter screen, it proved especially advantageous that filter screen has the mesh width of 120 μm to 160 μm.
First preferred modification provides: grid material is the grid material being made up of synthetic fibers, and wherein a variety of fibers are suitable.These include polyester (PES), particularly polybutylene terephthalate (PBT) (PBT) and polyethylene terephthalate (PET)；Polyamide, particularly aromatic polyamides (AF) and fatty polyamide, phthalic anhydride (PSA), polyphthalamide (PPA), polyphenylene sulfide (PPS), polyimides (PI), Polyetherimide (PEI), polyether-ether-ketone (PEEK), politef (PTFE), polysulfones (PSU), polyacrylonitrile (PAN), polyamide-imides (PAI).In addition, carbon fiber (CF) and glass fibre can be used, be both included as independent fiber or be used as the reinforcement (reinforcement) of above-mentioned fibrous material or following material: polyethylene (PE), polypropylene (PP), polystyrene (PS), Merlon (PC), polymethyl methacrylate (PMMA), epoxy resin fiber material or the fibrous material based on unsaturated polyester (UP) (UP).For independent fiber, it is also possible to use the compound of material mentioned above, copolymer and mixture.For textile material, it is also possible to use different fiber as warp thread and weft yarn.
It is particularly preferred that the textile material being made up of PTE, it is most preferred that be use not only textile material as warp but also the PET monofilament as parallel.
According to DINENISO13934, if synthetic fibers grid is shown as 80N/10mm to 150N/10mm in the both direction of warp thread direction and weft direction, is advantageously the tensile strength of 100N/10mm to 120N/10mm, then it is advantageous for.
In contrast, in second favourable modification, screen material is metallic mesh material, particularly steel lattice material.If using and there is 500N/mm2To 900N/mm2The tinsel (include or do not include limit value) of tensile strength, then it is particularly preferred.At this, tensile strength obtains from the standard for various metal materials.Screen material does not appear in the coating being filled with grid on its whole region.But, the silk thread of grid material can be coated with partially or completely.In this respect it is essential that grid stays open on the whole surface of filter mesh layer.
Smooth metal sealing layer can be made from a variety of materials.Given higher tensile strength, the sealant being formed from steel is preferred, thus sealant is made by carbon steel or by spring steel.Spring steel is particularly advantageous for there being the active layer of welding bead, but carbon steel is also suitable for this application.The preferred scope of layer thickness of active layer (includes these limit values) between 0.15mm and 0.3mm.For wall, especially for the wall of thickness of at least 0.5mm, use the metallic plate being made up of aluminum or aluminum alloy.Owing to smooth metal sealing layer is preferably only partially coated with the coating of polymer-matrix, therefore resistance to corrosion-resistant material is particularly preferred, for instance rustless steel or galvanized steel.
There is some probabilities in the master-plan for intermediate plate, the application of some probabilities depends on application, be particularly depending on the route of passage and the condition of fluid passage openings in passage guide part.
If the fluid openings of this passage and route are quite similar in two passage guide parts of adjacent intermediate plate, it is possible to provide the containment member of identical or essentially identical route on two surfaces of intermediate plate.For this, if this intermediate plate includes two smooth metal sealing layer (therefore two active layers and layout filter mesh layer between which) just, then it is preferred.By this layout, sheet metal plate is preferably used for two smooth metal active layer.
If there is a great difference the position of the fluid passage openings in two passage guide parts of the route of passage, adjacent described intermediate plate, then the different route of almost inevitable containment member.In this case, if this intermediate plate includes at least one sufficiently thick and resistant to bending wall, thus sealing line, be therefore incorporated into sealant as the screwing force of line pressure along it and the line between passage guide part and intermediate plate is separated from one another on the two of intermediate plate surfaces, then it is preferred.At this, it is advantageous to, if intermediate plate includes the smooth metal sealing layer of at least three and arranges filter mesh layer between which, thus after the active layer on outside described first and then wall, be then followed by filter mesh layer, subsequently and then outside another on the second active layer.The flexible of the gross thickness of this permission intermediate plate.Here, again as in example above, at least one but be preferably two sealants, particularly active layer and include steel.Third layer thus particularly wall can be made up of steel, aluminum or aluminum alloy.
Before multilamellar intermediate plate is arranged between passage guide part, the layer of this intermediate plate is preferably by the method for prior art and is connected to each other, the method of described prior art as known under the background of metal flat liner, for instance by welding, riveted joint and/or cooperate with method of attachment on one's own initiative without rivet or with other.
Except being used for fastening the full opening of access portal of component, can also including the full opening of access portal especially for fluid according to the intermediate plate of the panel of the present invention, described access portal need not any filtration.In these full opening of access portal, also it is left out filter mesh layer.
Control system according to the present invention finds it to apply in the following: especially in vehicle, especially as the control system for drive system, especially for Hydraulic Power Transmission System.In such applications, filter mesh layer retains the wear particle in oil circuit.

Detailed description of the invention
Fig. 1 illustrates the control system according to prior art, and Local map 1-a provides the top view of the intermediate plate 101 of control system.Local map 1-b illustrates two passage guide parts 102,103 and the cross section of layout intermediate plate 101 between which with cross sectional view.About the cross section shown in intermediate plate 101, Fig. 1-b corresponding to the section A-A in Fig. 1-a.Fig. 1-c is focused only on intermediate plate 101 and shows in detail intermediate plate 101 in Fig. 1-b with the region that broken box is prominent.
From Fig. 1, become clear that, intermediate plate 101 includes multiple passage opening, wherein passage opening 113 and passage opening 111,112 for fluid for fastening component can be different from each other, and intermediate plate 101 is connected to passage guide part 102,103 via passage opening 113 or is connected to optional feature place by passage guide part 102,103.Fluid is mainly hydraulic fluid, thus being usually hydraulic oil.Some are crossed over by filter screen extraly for passage openings (namely fluid passage openings 111) of fluid, this filter screen there is the path for fluid and sufficiently large but in order to keep the granule and sufficiently small mesh width carried in fluid here.Particularly, can be d/d and the granule of valve, sliding plunger etc. can be carried in no instance during operational phase early stage that these granules are new actuating device, this is owing to they can stop valve, sliding plunger.It addition, intermediate plate 101 includes the multiple fluid passage openings 112 worked without any filter screen.Herein, filter mesh layer 104 therefore it is left out.The shape of the opening in volume according to the fluid that must flow through and adjacency section, fluid passage openings 111 can have difformity, in the example shown as the fluid passage openings 111 different at three with filter screen.Fluid passage openings 111a illustrates rounded rectangle shape, longitudinally extends twice bigger than the prolongation of width herein.Therefore, its convex polygon that can be considered there is angle number n=4.Fluid passage openings 11b also show fillet and can be considered the concave polygon with n=8 angle.This polygonal spill makes this polygon illustrate contraction flow region.Fluid passage openings 111c is circular open, and this circular open also can be considered the polygon with the angle of indefinite number.
In the top view of Fig. 1-a, highlighting two projecting areas being provided with element 114, these two projecting areas are for the single layer connection each other of intermediate plate 101.It addition, the welding bead net (awebofbead) 163 of branch is being visible on the surface of separator in many ways；It is shown in phantom on the surface being directed away from separator of intermediate plate 101 with the second welding bead net of several means branch.Two welding bead systems are all used for sealing fluid passage openings.Although identical hydraulic fluid is by different fluid passage openings, but they must be sealed against one another, this is because different fluid passage opening or the hydraulic fluid from the channel part of these forehearth limbs have different pressure and/or different in flow rate to control sliding plunger, valve etc..In an identical manner, this intermediate plate needs to be sealed to and external environment.
Local map 1-b illustrates how two passage guide parts 102,103 make passage 120,130 continue through intermediate plate 101.In the example given, passage in upper channel guide part 102 is directed predominantly perpendicular to plotting planes and flows, and in lower channel guide part 103 (in the left cross section drawn and right section), show the passage 130 extended in drawing cross section, connected several passages 120 of upper channel guide part 102 by the passage 130 of intermediate plate 101.
From the sectional view of Local map 1-b and the cross section of intermediate plate 101 that provides from Local map 1-c, it becomes evident that, filter mesh layer 104 is arranged between active layer 106 and wall 105, and another active layer 107 is arranged on below wall 105.Each in upper active layer 106 and lower active layer 107 includes welding bead 163,173, and welding bead 163,173 is adjacent to fluid passage openings 111,112 and extends and this can provide the sealing of convection cell passage opening 111,112.Fig. 1-b illustrates only in realizing welding bead in such region: in this region, the regional of intermediate plate rests on passage guide part.
As already mentioned, some fluid passage openings (that is, fluid passage openings 111) include filter screen 104, and other fluid passage openings (that is, fluid passage openings 112) works without these filter screens.If the fluid passage openings 111 that fluid is by being crossed over by a part for filter mesh layer, then this part covering corresponding fluid passage openings 111 of filter mesh layer 104 is loaded with pressure, and this load is more big, then fluid pressure is more big and its pulsation is more big.Therefore, the grid material of filter mesh layer 104 is stretched, and grid material expands in the plane, and it is crossed in other region between the smooth metal level 105,106 in intermediate layer 101.If if the fluid in particular fluid passage opening 111 not always in a same direction flowing or stop but its stop in this fluid passage openings 111 or when a direction or the opposing party flow up according to mode of operation, then this effect increase.Change along with each direction, affected filter mesh layer part from be adjacent to filter mesh layer 104 arrange smooth metal level 105,106 between plane stir and run in this process stirred in each sealant 105,106 the circumferential edge of passage opening 111, the particularly linear compression in its edge part, at its edge part place, it is against contiguous smooth metal sealing layer 105,106.
Under the long period of operation replaced by frequent load, this can cause the abrasion of grid material individually and cause wall scroll silk thread or fracture wiry.Once several silk threads or tinsel are separated, then it is easy to extrude region, cut edge towards both direction and increase the fracture of neighbouring silk thread or metal wire.One of result of this effect is, it does not have granule can stick in individual channel opening 111, and therefore filter mesh layer 104 is no longer able to continue the task of its reality.Even worse, each bar silk thread or metal line portions can be cut off, and each bar silk thread being then cut off or metal wire are carried in fluid line and itself are likely to afterwards stop sliding plunger, valve etc..
If the edge of the fluid passage openings 111 that too much burr, such as punching burr are in contiguous laying provides, then increase this effect.These punching burrs are formed in each metallic plate, and meanwhile, passage opening is particularly stamped out on the side that the entrance side with instrument of metallic plate is relative.
This is can not be received in hydraulic control system.The invention solves this situation: being provided with at least one in the one of the adjacent filter mesh layer of smooth metal sealing layer and support layout, the expansion and the stretching that prevent filter mesh layer are arranged in this support.Fig. 2 is illustrated as the example of the control system according to the present invention.The top view of Fig. 2-a shows intermediate plate 1, this intermediate plate 1 generally can compared with the intermediate plate 101 of display in Fig. 1-a, but this intermediate plate 1 is at the passage opening 11 filled especially, such as include bridge 41 at punctured position 47 place, this bridge 41 stretches out and across the edge at (bridge) this passage opening 11 from the edge of this passage opening 11.Also according to the positions and dimensions of passage opening and path 20,30, the passage guide part 2,3 in Fig. 2 is corresponding to the passage guide part 102,103 in Fig. 1.
The layout supporting layout and design for filter mesh layer part are shown specifically in the following Local map of Fig. 2.From Fig. 2-b and Fig. 2-c (it relates to the section B-B Fig. 2-a), it becomes obvious that passage opening 11 farther on the left of positional distance is simply filled with less pressure and/or unchanged and therefore do not need additional support on the path direction of fluid.The passage opening 11 ' (passage opening 11 ' refers to passage opening 11a in fig. 2 to mark its shape) being located closer to right side than passage opening 11 is crossed over by filter screen equally.Be different from passage opening 11, passage opening 11 ' in the face of arrive from below top high pressure loading and due to during when flows downward pressure ratio be derived from that the pressure flowing up direction is fairly small and the change of path direction.In order to prevent the filter mesh layer 4 destruction in the region of this fluid passage openings 11 ', this fluid passage openings 11 ' is disposed in the bridge 41 ' in the smooth metal sealing layer 6 at the rear (relative to main flow direction) of filter mesh layer 4 and crosses over, and this bridge is at two transverse sides of the only about half of place connecting path opening 11 ' of the longitudinal stretching of passage opening 11 '.Bridge 41 ' shows the width of about 1/6 of the longitudinal stretching corresponding to passage opening and therefore not excessively reduces passage region.Although the passage opening 11 ' in the region of sealant 6 is separated by bridge and is divided into two parts, but it is never considered single passage opening, as shown in Fig. 2-b, because passage opening 11 ' is continuous up and down in single passage 20 or 30 respectively.Even at the side in only one passage continuously for considering that passage opening is enough, this passage opening is divided into single fluid passage openings 11 as described above.
Although the bridge in Fig. 2-b 41 ' is as fluid passage openings 11 ' is completely covered, but from Fig. 2-d it becomes obvious that bridge 41 ' only partially covers fluid passage openings 11 ', Fig. 2-d shows the cross section in the cross section being orthogonal in Fig. 2-b, that is, the cross section C-C of Fig. 2-a.Fig. 2-d and Fig. 2-e also shows, at passage opening 11 " in filter mesh layer 4 (on its bottom side) also prevent by the bridge 41 of partly adjacent filter mesh layer 4 " excessive deformation that causes.In the top view of Fig. 2-a, this bridge 41 " covered by filter mesh layer and be therefore sightless.In the process of operation control system, strong pulsed flow fills filter screen under flowing to, it means that the operable state with not fluid alternates with big downward fluid stream.This, bridge 41 " formed in wall 5, and the bridge 41 ' of passage opening 11 ' formed in active layer.Although wall 5 shows bigger material thickness, but active layer 6 shows bigger deformation rigidity and bigger flexure, thus having and the bridge 41 ' of fluid passage openings similar sizes and close pressure loading and bridge 41 " about the same width can be designed with.It is essential, support and arrange that formation is in being just adjacent to the sealant 5 of filter mesh layer 4, sealant 6 and sealant 7.
Fig. 2 is respectively provided with apostrophe 11,11 ', 11 " with 41,41 ', 41 " symbol be only respectively used to the different passage opening of mark and supporting and arrange, it is considered but does not mean that its function of differentiation or they are restricted to its function.From the sectional view of Fig. 2, becoming readily apparent from, the passage 20,30 in passage guide part and potted component (at this therefore for welding bead 63,73) has different route.This basic structure being required for treating the suitably selected intermediate plate of pressure of fluid sealed against one another, i.e. utilize wall 5 to make sealing bead 63,73 separate.
Fig. 3, for illustrating the possible basic structure of the intermediate plate 1 of the control system according to the present invention, supports, to the present invention is vital, the design arranged without setting forth.Fig. 3-a shows have the smooth metal sealing layer of total of three 5,6,7 thus the structure of intermediate plate 1 of sheet-metal layers and a filter mesh layer 4.The bottom side of upper channel guide part 2 adjoins the first active layer 6, and wall 5 is arranged in the latter's (the first active layer 6) lower section.Filter mesh layer 4 adjoins this wall 5, and the second active layer 7 is between filter mesh layer 4 and lower channel guide part 3.Active layer 6,7 includes welding bead 63,73, the head points passage guide part 2,3 of this welding bead 63,73.Welding bead 63,73 is around passage opening 11 with in some cases around the passage 20,30 in passage guide part 2,3.In each in multiple welding beads, on the surface pointing to passage guide part 2,3 of welding bead, coating 64,74 is such as coated with by screen printing.This coating not only covers each welding bead but also covers the region of the foot being adjacent to welding bead, it means that the whole width of coating corresponds to 1.5 times of the developed width being a bit larger tham welding bead.Same it becomes obvious that the edge of this coating direct path opening 11 from this diagram.Although in cross section shown in Fig. 3-a, the welding bead 63 of upper active layer and welding bead 73 one of lower active layer 7 are positioned on another one, but they differently extend in other position.For this, wall 5 is arranged between active layer 6,7 herein, and this is that the separation of potted component is prepared, thus they can be compressed independently of one another.
By contrast, the structure in Fig. 3-b and Fig. 3-c is more suitable for intermediate plate, and wherein, the welding bead system 63,73 of two active layers extends substantially parallel, thus they more enhance the sealing effectiveness of each of which, but can not make sealing line separately.In two structures, filter mesh layer 4 is centered around between two active layers 6,7, in Fig. 3-a, wherein, and the head points passage guide part 2,3 of the welding bead of two active layers 6,7.Although the active layer in Fig. 3-b 6,7 uses welding bead 63,73 as containment member, but in the structure of Fig. 3-c, use partial coating in either case, its respectively active layer 6,7 towards on the surface of passage guide part around passage opening 11 or passage 20,30.In all the drawings (not only in figure 3), to such as wall 5 or on the surface being directed away from passage guide part 2,3 of active layer 6,7 optional being expressly recited of region-wide coating be omitted.
Fig. 4 shows the top view of the edge part of another intermediate plate of prior art.Except being used for fastening the passage opening 113 of component, recognizable by welding bead 163 around circular flow passage opening 111c.At this again by strong impulses fluid-load, give the excessive tensile of the part crossing over fluid passage of filter mesh layer 104 and the risk of destruction.
Compared to the edge part of the intermediate plate of display in Fig. 4, Fig. 5 shows the edge part of the intermediate plate of the control system according to the present invention, is wherein arranged on the edge of fluid passage openings 11 as two extensions 42 arranged that support for filter mesh layer 4.At this, pulsed flow shows its main flow direction on flowing to, (as in Fig. 5-c it can be seen that) extend into and makes in fluid passage openings 11 continuous print region thus extension on the upside of filter mesh layer 4, and also projects into by this way in the region of the passage 20 in upper channel guide part 2.In the projection to a plane total with fluid passage openings 11, the two structure overlaps each other.The welding bead of two active layers 6,7 shows similar route at this on whole intermediate plate, even for parallel line in the cross section shown in Figure 5.Therefore, there is no need to separate welding bead 63,73, thus being not provided with welding bead 63,73 and being laterally abutted wall and the coating in region.Structure in Fig. 5 therefore corresponds to the structure in Fig. 3-c.
In figure 6, it is shown that the modification of another novelty in the cross section of intermediate plate shown in Fig. 4.At this, in the edge of generally rounded fluid passage openings 11, the extension 42 of three rule layouts is configured to avoid the support of the excessive tensile of filter mesh layer 4 to arrange.Each in extension extend in this opening to reach 1/3 (this 40 limits by a dotted line) of the diameter 48 of the fluid passage openings 11 being slightly less than reality, and which prevent excessive tensile or the destruction of the part in passage opening 11 of filter mesh layer.
Fig. 7 illustrates another embodiment of the control system according to the present invention.At this, intermediate plate 1 includes two active layers 6,7 and the filter mesh layer 4 between two active layers 6,7.Pointing at it of active layer 6,7 has the partial coating 65,75 as containment member in each in the surface of passage guide part 2,3.The shown whole strong impulses being filled partially with controlling fluid, arranges thus all fluid passage openings 11 (it does not show independent accompanying drawing labelling at this) are provided with the support for filter mesh layer 4.The part corresponding to the region D in Fig. 7-a of intermediate plate 1 is shown specifically in Fig. 7-b, and the part corresponding to the region E in Fig. 7-a of intermediate plate 1 is shown specifically in Fig. 7-c.The passage opening being positioned at the leftmost side is filled with extremely powerful pressure on two flow directions, and is frequently changed on the direction controlling fluid, thus at this, supporting and arrange the bridge 41* including being positioned on the both sides of filter mesh layer 4.So, it is to avoid filter screen part stretching in the two directions, thus it can immobilized particles chronically.Both sides bridge 41* there is shown herein identical stretching.
Route along the intermediate plate 1 in Fig. 7-a is advanced further towards right side, then, one part occurs: in the portion, the passage 20 in upper channel guide part 2 covered by the two of intermediate plate smooth metal levels 6,7 and by the coating portion 65 of active layer 6 safely around.Filter mesh layer 4 in this region does not have filtering function owing to it is capped, but between active layer 6,7 continuously.This manufacture being not only convenient for filter mesh layer also makes filter mesh layer self-stabilization.Further towards to the right, fluid passage openings occurs: this fluid passage openings is simply filled with gentle pulse compared to other fluid passage openings shown in Fig. 7, thus being only only provided in upper active layer 6 as the extension 42 arranged that supports for filter mesh layer 4.As in figure 6, it is possible to provide three extensions 42, but only one in them can be identified in cross sectional view.
Even further towards the right side in the route of the intermediate plate 1 in Fig. 7-a, and therefore on the left-hand side in the detailed view in Fig. 7-c, passage opening occurs: but provide high fluid pressure only by upwelling, passage opening faces more intensive pulse than the multiple passage openings described by the preceding paragraph.Therefore, a bridge 41 on the upper surface of filter mesh layer 4 is enough to arrange as the support for this filter screen part.Filter screen 41 is substantially perpendicular to the doube bridge 41* of the fluid passage openings 11 provided and extends to the leftmost side in Fig. 7-a.
Next fluid passage openings (one, the centre in Fig. 7-c fluid passage openings) shows the area bigger than the fluid passage openings described by before (in the context of Fig. 7) on the whole.The filter screen part that here it is shown that faces high downward fluid pressure and somewhat smaller to the strong pulse between upper fluid pressure.Face this problem, but in order to not make passage region excessively loose, the bridge on the both sides of this doube bridge 41*, therefore filter mesh layer is arranged on the right-hand side, and little simple bridge 41 is arranged on left-hand side.On the bottom side of filter mesh layer 4, therefore needing on the surface better supported, two bridges are so provided, and the simple bridge simultaneously as a part of doube bridge 41* is enough on the top side of filter mesh layer 4.
The fluid passage openings being arranged in ultra-Right side is only filled with pressure in an upward direction, but it is showing the very big area of passage, thereby through using to be arranged in upside upper and just prevent the possible deformation and failure of filter screen part of correspondence at the rear of filter mesh layer 4 as supporting the bridge 41 arranged.
In two Local maps, Fig. 8 shows in the smooth metal sealing layer being adjacent to filter mesh layer, two embodiments of the particularly design of the bridge in active layer 6,7.This diagram is only illustrative, and particularly each in multiple angles of passage opening 11 illustrates by this way so that provide each polygonal angle when needleless is to the radius that acceptable use time of instrument is required in practice.Fig. 8-a shows the convex pentagon of the rule of the basic configuration as passage opening 11.The tip that bridge 41 is substantially relative with this center from the centre pull of pentagonal side to position, and it is from this side to the route at this tip, its width is reduced about 15%.Representing that with the dotted line 40 of strip the imagined extension at the edge of passage opening 11 divides, therefore the shape of passage opening is possibly shown as without supporting bridge 41.This pentagon includes total of five diagonal 45, and these five diagonal 45 all intersect with support bridge.
Fig. 8-b is different from the place of Fig. 8-a and is in that: the passage opening 11 covered by filter mesh layer 4 on its bottom side shows the convex pentagon as its basic configuration.Again, the edge covered by bridge of passage opening is represented by dotted line 40.At this, bridge 41 again show over the whole length without constant width.But, bridge 41 is widened towards its end, thus creating the roomy rounded transitional of transverse edge towards passage opening.Again, support bridge location in this in the minds of, thus it intersects with all of diagonal.
In 8-a and Fig. 8-b, the hithermost each other junction point 46,46 ' of bridge 41 is spaced apart separately from each other relative to the circle around pentagon or hexagonal central point more than 120 ° on an opposed edge thereof.Respectively, spaced apart separately from each other relative to the circle around pentagon or hexagonal central point substantially 180 ° of two centrages 49,49 ' of the virtual transverse edge towards passage opening of the transition part of each bridge.
