Description
Foreliggende oppfinnelse vedrører en hydraulisk maskinstyring som består av fordelerplater eller blokksegmenter, på hvis utsider de nødvendige ventiler er anordnet og hvorved de enkelte blokksegmenter er sammenføyet med hverandre til en styreblokk og holdt sammen med spennstenger. The present invention relates to a hydraulic machine control which consists of distributor plates or block segments, on the outside of which the necessary valves are arranged and whereby the individual block segments are joined together to form a control block and held together with tension rods.
Ventilsammenkoblinger for oppbygging av komplekse hydrauliske styresystemer ved sammenskruing av fordelerplater med derpå påflensete ventiler er kjent som høyde- og lengdesammenføyninger i de mest ulike utførelsesformer. Fordelerplatene holdes sammen med spennstenger eller skrues sammen, den ene til den andre. Pumpetilkoblingen, tanktilkoblingen såvel som tilleggsboringer for en adskilt styrekrets føres i sammenføyningsretningen gjennom fordelerplatene*. De nødvendige ventiler skrues med sine hus på disse fordelerplater som platepåbyggingsventiler, idet flere ventiler kan være montert på fordelerplatenes fri sider. De enkelte fordelerplatene inneholder videre minst to forbrukertilkoblinger, såvel som etter behov måletilkoblinger. Valve connections for the construction of complex hydraulic control systems by screwing together distribution plates with valves attached thereto are known as height and length connections in the most different forms of execution. The distributor plates are held together with tension rods or screwed together, one to the other. The pump connection, the tank connection as well as additional bores for a separate control circuit are led in the joining direction through the distributor plates*. The necessary valves are screwed with their housings onto these distributor plates as plate-mounted valves, since several valves can be mounted on the free sides of the distributor plates. The individual distributor plates also contain at least two consumer connections, as well as, if necessary, measuring connections.
En maskinstyring som er sammensatt på denne måte av blokksegmenter har den fordel at den er sammensettbar som et byggesett av pre-fabrikerte plater - blokksegmentene - og motsvarerende kompakt opp-bygget. En rørmontering innspares, siden blokksegmentene allerede er forsynt med tilsvarende boringer som danner væskeledningene. A machine control which is composed in this way of block segments has the advantage that it can be assembled as a building kit of pre-fabricated plates - the block segments - and the corresponding compact structure. A pipe assembly is saved, since the block segments are already provided with corresponding bores that form the liquid lines.
Disse er til å begynne med minst to i sammenføyningsretningen ut-førte boringer, for forbindelse med en trykkmediumkilde og en tanka såvel som tverrboringer for påbygging av tilsvarende ventiler på segmentutsiden. These are initially at least two bores made in the joining direction, for connection with a source of pressure medium and a tank, as well as transverse bores for fitting corresponding valves on the outside of the segment.
Oppfinnelsen vedrører en slik sammenføyning av blokksegmenter, men har til oppgave å utforme en således tildannet styreblokk ennå The invention relates to such a joining of block segments, but has the task of designing a thus formed control block yet
mer sammentrengt og oversiktligere.more condensed and clearer.
Dette oppnås ifølge oppfinnelsen ved at det for styring av hoved-strømmen benyttes forstyrte kjegleseteventiler og at disse er direkte integrert i de enkelte blokksegmenter på en slik måte at segmentene er forsynt med boringer for opptak av disse ventilelementer, som består av ventilføringshylse, sperrekjegle og trykkfjær, og at bare forstyringsventilene og innstillingsorganene er anordnet utenpå blokksegmentene. This is achieved according to the invention by the fact that baffled cone seat valves are used to control the main flow and that these are directly integrated into the individual block segments in such a way that the segments are provided with bores for receiving these valve elements, which consist of a valve guide sleeve, stop cone and compression spring , and that only the pilot valves and setting members are arranged outside the block segments.
Seteventilelementene er hensiktsmessig slik integrert i platene,The seat valve elements are appropriately integrated into the plates,
at det ved tilsvarende styring over forstyringsventiler med liten nominell vidde kan forbindes to forbrukertilkoblinger etter valg med trykkmediumkilden eller tanktilkoblingen. Man oppnår en ventil-enhet som med hensyn til byggevolum, kostnader og strømningstap er særlig fordelaktig, siden hovedstrømmene ledes av den gjennomgående trykk- og tankboringen til og fra forbrukertilkoblingene bare inne i segmentene og ikke trenger å flyte utad over påflensete ventilhus* that by corresponding control over pre-control valves with a small nominal width, two consumer connections can be connected as desired with the pressure medium source or the tank connection. A valve unit is obtained which, with regard to construction volume, costs and flow losses, is particularly advantageous, since the main flows are led by the continuous pressure and tank bore to and from the consumer connections only inside the segments and do not need to flow outwards over flanged valve bodies*
Segmentene er hensiktsmessig forsynt med to gjennomgående opptil hverandre liggende tverrboringer. I disse tverrboringer er det i hvert enkelt på platens underside integrert et seteventilelement. Tvers over disse to boringer løper en tredje boring, som skjærer The segments are appropriately provided with two cross-borings located through and next to each other. In each of these cross bores, a seat valve element is integrated on the underside of the plate. Across these two bores runs a third bore, which cuts
de første to boringene og dessuten står i forbindelse med den loddrett gjennom platene gående tankboringen. I denne tredje boring er det på begge utsider integrert seteventilelementer. Dessuten er det anordnet en fjerde tverrboring i de andre tverrboringenes plan, som forbinder de to første boringene med hverandre. I den fjerde tverrboringen munner det ytterligere en boring ut, som er parallell med de to gjennomgående, véd siden av hverandre liggende tverrboringene og som likeledes er forsynt med et seteventilelement. the first two boreholes and are also connected to the tank borehole running vertically through the plates. In this third bore, seat valve elements are integrated on both outsides. In addition, a fourth transverse bore is arranged in the plane of the other transverse bores, which connects the first two bores with each other. In the fourth cross-boring, a further bore opens out, which is parallel to the two continuous cross-borings lying next to each other and which is likewise provided with a seat valve element.
Ved. den valgte anordningen av fem forstyrte kjegle*-seteventilelementer i et segment kan de viktigste styringer av hydrosylindre eller -motorer realiseres i et segment. By. the chosen arrangement of five disrupted cone* seat valve elements in a segment, the most important controls of hydraulic cylinders or motors can be realized in a segment.
Et blokksegment ifølge oppfinnelsen er vist skjematisk på tegningen, delvis i snitt. A block segment according to the invention is shown schematically in the drawing, partly in section.
Blokksegmentet betegnes med 1. Det har to gjennomgående, ved siden av hverandre liggende tverrboringer 2 og 3. På tvers av disse to boringene forløper det en tredje boring 4, som skjærer de to første boringene 2 og 3 og dessuten står i forbindelse med en gjennom segmentet loddrett gående tankboring 5. I planet til disse tverrboringer 2, 3, 4 befinner det seg en fjerde tverrboring 6 som for binder de to boringene 2 og 3 med hverandre, såvel som ytterligere boring 7, som forløper parallelt med de to boringene 2 og 3 og står i forbindelse med boringen 8, som kommer fra trykkmediumkilden. The block segment is denoted by 1. It has two continuous, side-by-side cross bores 2 and 3. Across these two bores runs a third bore 4, which intersects the first two bores 2 and 3 and is also connected to a through segment vertically running tank bore 5. In the plane of these cross bores 2, 3, 4 there is a fourth cross bore 6 which connects the two bores 2 and 3 with each other, as well as a further bore 7, which runs parallel to the two bores 2 and 3 and is in connection with the bore 8, which comes from the pressure medium source.
I blokksegmentet 1 er det utført boringer 9 hvor igjennom det er ført spennstenger som holder sammen flere blokksegmenter i en styreblokk. In the block segment 1, bores 9 have been made through which tension rods have been passed which hold together several block segments in a control block.
For styringen benyttes forstyrte kjegleseteventiler, som er direkte integrert i blokksegmentet 1. Disse ventiler er betegnet med 10, 11, 12, 13 og 14. Hver ventil består av en ventilføringshylse 15, en sperrekjegle 16 og en ventilfjær 17, som vist ved ventilen 12. For the control, baffled cone seat valves are used, which are directly integrated into the block segment 1. These valves are designated by 10, 11, 12, 13 and 14. Each valve consists of a valve guide sleeve 15, a stop cone 16 and a valve spring 17, as shown at valve 12 .
Utenfor blokksegmentet befinner det seg forstyringsventiler 20 så vel som instillingsorganer 18 og 19. Outside the block segment, there are pilot valves 20 as well as setting members 18 and 19.
Ventilene 10, 11, 12 og 13 overtar i prinsippet vegventil- hen-holdsvis koblingsfunksjonene, idet strupefunksjoner er mulig ved innbygging av en lufttilførselsbegrensning av innstillingsorganene 18 og 19. Forstyringen av disse fire element skjer over en forstyringsventil 20 som forbinder kjegleseteventilenes styresider 22 motsvarende koblingsfunksjonene over i segmentet inngående styre-boringer med trykkboring 8 eller tankboring 5, hvorved disse kob-les inn eller ut. In principle, the valves 10, 11, 12 and 13 take over the road valve, respectively, the switching functions, as throttling functions are possible by incorporating an air supply limitation of the setting devices 18 and 19. The piloting of these four elements takes place via a piloting valve 20 which connects the control sides of the cone seat valves 22 corresponding to the switching functions above the control bores included in the segment with pressure bore 8 or tank bore 5, whereby these are switched on or off.
Pålegges for eksempel alle ventilene 10, 11, 12 og 13 på styresiden trykk og lukkes på denne måte, så sperres forbrukertilkoblingene A og B. Avlastes elementene 10 og 13 på styresiden, så åpner de og trykkmediet flyter fra boringen 8 over boringen 6, ventilen 10 og boringen 2 til forbrukeren og derfra gjennom boringen 3 og ventilen 13 tilbake til tanktilkoblingen 5. For example, if pressure is applied to all valves 10, 11, 12 and 13 on the control side and closed in this way, the consumer connections A and B are blocked. If the elements 10 and 13 on the control side are relieved, they open and the pressure medium flows from bore 8 over bore 6, the valve 10 and the bore 2 to the consumer and from there through the bore 3 and the valve 13 back to the tank connection 5.
Med ventilen 14 kan de viktigste tilleggsfunksjoner for hvert enkelt element realiseres, F. eks. kan ventilen 14 settes inn sammen med en ytterligere forstyringsventil 21 som trykkreduse-ringsventil mellom pumpetilkoblingen 8 og trykktilkoblingen til hvert enhetssegment, slik at det i hvert segment er mulig å fore-ta en spesiell, redusert trykkinnstilling. Ved innebygging av en mengderegulator i form av en innbyggingspatron i stedet for kjegle-seteventilelementet 14, kan gjennomstrømningen til forbrukere reguleres. With the valve 14, the most important additional functions for each individual element can be realised, e.g. the valve 14 can be inserted together with a further pilot valve 21 as a pressure reduction valve between the pump connection 8 and the pressure connection of each unit segment, so that in each segment it is possible to make a special, reduced pressure setting. By incorporating a quantity regulator in the form of a built-in cartridge instead of the cone seat valve element 14, the flow through to consumers can be regulated.
For ytterligere tilleggsfunksjoner, som ikke kan realiseres ved hjelp av ventilene 10-14, kan det på flaten mellom forbrukertilkoblingene A og B skrues på flenshus for strupeventiler, mengde-reguleringsventiler og sperreventiler. Dermed kan styreomfanget for de enkelte segmenter utvides betydelig. Skal det imidlertid herske samme trykk i alle enkeltelementer, så kan ventilen 14 utelates. Ved et slikt system kan oppfinnelsesideen belyses særlig enkelt. Trykkmediet flyter fra tankboringen 5 og boringen 6 sammen til de to ventilene 12 og 13. Arbeidsventilene 10 og 11 sitter nøye loddrett i forhold til disse i ledningen 6. Dette gir en meget enkel utforming. For further additional functions, which cannot be realized with the help of valves 10-14, on the surface between the consumer connections A and B, flange housings for throttle valves, quantity control valves and shut-off valves can be screwed on. In this way, the scope of management for the individual segments can be significantly expanded. However, if the same pressure prevails in all individual elements, then the valve 14 can be omitted. With such a system, the invention idea can be elucidated particularly easily. The pressure medium flows from the tank bore 5 and the bore 6 together to the two valves 12 and 13. The working valves 10 and 11 sit carefully vertically in relation to these in the line 6. This gives a very simple design.
