Description

DK 162115 BDK 162115 B

Opfindelsen angår en skyder til skydeventil, som set ovenfra har en langstrakt, især oval yderkontur, er anbragt på tværs af strømningsretningen i skydeventilhuset og kan forskydes af spindelen i spindellængderetningen fra 5 en åbnestilling til en lukkestilling, hvorhos skyderen bærer en på det rå støbejernslegeme fast anbragt, elastisk eftergivelig eller elastomer kappe, hvis tætningsafsnit i skyderlukkestillingen er indrettet til at ligge elastisk an mod skyderventilhusets sideflader, og ved sine to smalsider 10 har to overfor hinanden beliggende, i spindellængderet ningen forløbende føringsafsnit med indsatte giideplader, som er indrettet til at holde an mod skydeventilhusets modføringsafsnit .BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a sliding valve slider having an elongate, particularly oval outer contour, viewed transversely of the flow direction in the sliding valve housing, and can be displaced by the spindle lengthwise from an opening position to a closing position where the slider carries one on the raw cast iron body. a resiliently resilient or elastomeric sheath whose sealing portion in the slider closing position is arranged to resiliently abut the side faces of the slider valve housing, and at its two narrow sides 10 have two oppositely extending, spindle-length guide portions with inserted guide plates for holding against the sliding valve housing counter section.

Fra DE-OS 16 00 745 er der kendt en blødtættende 15 skyder af ovennævnte art med en elastisk eftergivelig kappe, ved hvilke skyderens føringsribber tillige kan være forsynet med indvulkaniserede metalliske føringsskinner. Enkeltheder derved, såsom hvorledes disse føringsskinner er udformet og om de træder foran kappen, fremgår ikke af 20 trykskriftet. Bortset fra vulkaniseringen består der ved disse føringsskinner ingen yderligere forbindelse med den indhyllede skyder. Det elastiske overtræk med den underste tætningsliste er her klæbet eller vulkaniseret på lukkelegemet, mens den øvre elastiske tætningsvulst som en løs 25 ring er påsat skyderen. Skyderen er som følge af den løse påsatte øverste tætningsvulst ikke tilstrækkelig korrosionsbeskyttet .DE-OS 16 00 745 discloses a soft-sealing 15 slider of the above-mentioned type with an elastic resilient sheath, in which the slider guide ribs may also be provided with indulgent metallic guide rails. Details thereof, such as how these guide rails are designed and whether they step in front of the jacket, do not appear in the printing press. Except for the vulcanization, there is no further connection with the casing slider with these guide rails. The elastic cover with the lower sealing strip is here adhered or vulcanized to the closure body, while the upper elastic sealing bead is attached to the slider as a loose ring. The slider is not sufficiently corrosion protected due to the loose applied top seal bead.

Fra FR-OS 21 21 268 er der yderligere kendt en med en elastisk eftergivelig kappe forsynet skyder af jern, 30 der til sin føring i skyderhuset har særlige sideværts udragende og i tværsnit retvinklede længdeføringsribber, der længdeforskydeligt føres i skyderhusets føringsnoter. Gummieringen af skyderen er afbrudt ved føringsribberne, og på disse føringsribber af jern er beskyttelseskapperne af 35 ikke-rustende stål eller af kunststof påsat ved en klemvirkning, som afdækker føringsribberne på alle udvendige sider og som skal forbedre giideegenskaberne i længdeførin-From FR-OS 21 21 268 there is further known an iron slider provided with an elastic resilient sheath, which has special laterally projecting and cross-sectional rectangular longitudinal ribs which are slidably longitudinally inserted in the slider housing guide notes. The rubberization of the slider is interrupted by the guide ribs, and on these iron guide ribs the protective sheaths of 35 non-rusting steel or of plastic are applied by a clamping action which covers the guide ribs on all outside sides and which is intended to improve the guide properties in longitudinal directions.

2 gen såvel som korrosionsbeskyttelsen. De i tværsnit U-formede beskyttelseskapper danner herved med deres ydre forside og de to hertil retvinklede tilstødende ydre sideflader de på de tre sider af husføringsnoten anliggende 5 giideflader. Disse blot påsatte beskyttelseskapper sikrer ingen tætnende indkapsling af føringsribben mod omgivelserne, så skyderen kan ruste på disse føringsribber. Desuden kan disse løst påsatte beskyttelseskapper løse sig fra føringsribberne ved forkantning af skyderen, der er ensi-10 digt påvirket af medietrykket.2 gene as well as the corrosion protection. The cross-sectional U-shaped protective caps thereby form with their outer front and the two adjacent outer side surfaces at right angles the 5 guide surfaces on the three sides of the housing note. These simply fitted protective caps ensure no sealing enclosure of the guide ribs against the surroundings, so the slider can rest on these guide ribs. In addition, these loosely attached protective caps can be detached from the guide ribs by cutting off the slider, which is uniquely influenced by the medium pressure.

Opfindelsens formål er derfor at udforme skyderen således, at de indsatte giideplader ved gode giideegenskaber på enkel vis er sikkert forankret på skyderen, hvorved skyderen på hele den samlede overflade, d.v.s. også 15 i føringsafsnitsområdet, er sikkert beskyttet mod korrosion.The object of the invention is therefore to design the slider such that the inserted guide plates with good guiding properties are simply anchored to the slider, whereby the slider on the entire overall surface, i.e. also 15 in the lead section area, are safe from corrosion.

Dette formål opnås ved det i krav 1 angivne.This object is achieved by the method of claim 1.

Den fast anbragte elastisk eftergivelige kappe omgiver fuldstændigt skyderen og beskytter derved denne mod 20 korrosion. GIidepladerne med de gode giideegenskaber i kappen af det lukkede elastisk eftergivelige lag er yderligere forankret gennem forbindelsesbroen, og ved kappens omgriben af giidepladen gives en sømløs tætning og dermed korrosionssikker overgang fra kunststofgiidepladen til den 25 elastisk eftergivelige kappe af skyderen. Da giidepiadepar-rets forbindelsesbro er forsynet med forankringsgennem-brydninger og indlejret i den elastisk eftergivelige kappe, er disse særligt godt forankret i det elastisk eftergivelige materiale.The rigidly resilient resilient sheath completely surrounds the slider, thereby protecting it from corrosion. The guide plates with the good guide properties in the casing of the closed elastic resilient layer are further anchored through the connecting bridge, and at the casing's circumference of the guide plate, a seamless seal and thus corrosion-resistant transition from the plastic guide plate to the 25 resilient resilient jacket of the slider is provided. Since the connecting bridge pair of bridge guides are provided with anchoring breakages and embedded in the resilient resilient sheath, these are particularly well anchored to the resilient resilient material.

30 Fra tidsskriftet Kunststoff-Rundschau, august 1970, hefte 8, side 378 til 380, er det desuden alment kendt, at giidelag af polyamid besidder meget gode giideegenskaber .30 Furthermore, from the journal Kunststoff-Rundschau, August 1970, booklet 8, pages 378 to 380, it is well known that polyamide guide layers have very good guide properties.

Ved det i krav 2 angivne er giidepladerne på 35 deres mod skyderen anliggende inderside forsynet med forankrings- eller tilbagespringende dele og/eller med i sideretningen udragende forankringsansatse, således at der er 3In the case of claim 2, the guide plates on their inside facing the slider are provided with anchoring or back-projecting parts and / or with laterally extending anchorage members, so that there are 3

5 Fortrinsvis bærer giidepladen ifølge krav 3 mod skyderen afbøjede holdelister med forankringsgennembryd-ninger, der ligger på den indvendige kappe og i det mindste er delvis indlejret i den ydre elastisk eftergivende kappe, således at der her igennem opnås en ekstra forankring af 10 giidepladen på skyderen.Preferably, the guide plate of claim 3 carries deflected retaining strips with the anchor breakthroughs which lie on the inner sheath and are at least partially embedded in the outer resilient resilient sheath, thereby providing an additional anchorage of the guide plate on the slider. .

Opfindelsen vil i det følgende blive nærmere forklaret i forbindelse med et par udførelseseksempler og under henvisning til tegningen, hvor fig. 1 viser en glidepladeforsynet ventilskyder med elas-15 tisk eftergivelig kappe set forfra, fig. 2 i den øverste tegningshalvdel den samme skyder set ovenfra og i den nederste tegningshalvdel i snit efter linien II—II i fig. 1 med to forskelligt udformede gli-deplader, 20 fig. 3 en anden skyder med på smalsiderne anbragte, udad fremspringende glidepladebærende føringslister, hovedsageligt i længdesnit, fig. 4 skyderen ifølge fig. 3 set ovenfra, og fig. 5 en føringsliste på skyderen ifølge fig. 4 med på-25 satte glideplader i større målestoksforhold.The invention will be explained in more detail below with reference to a few embodiments and with reference to the drawing, in which fig. 1 is a front view of a sliding plate-fitted valve slider with an elastic resilient sheath; FIG. 2 in the upper drawing half shows the same view from above and in the lower drawing half in section along the line II-II in fig. 1 with two differently shaped slide plates, 20 fig. Fig. 3 shows a second slider with the narrow sides, projecting outwardly extending sliding plate bearing guides, mainly in longitudinal section; 4 shows the slider according to FIG. 3 is a plan view of FIG. 5 shows a guide strip on the slider according to FIG. 4 with mounted slides in larger scale conditions.

Den i fig. 1 og 2 viste gummibelagte ventilskyder 1 har set ovenfra en oval yderkontur 2 og er indsat i det ikke viste skydeventilhus på tværs af strømningsretningen.The FIG. 1 and 2, rubber-coated valve slides 1 have a top view of an oval outer contour 2 and are inserted into the slide valve housing not shown across the flow direction.

Den udgøres i det væsentlige af det rå støbejernslegeme 3 30 og den påsprøjtede elastisk eftergivelige kappe 4. I nærheden af de med skyderventilhusets sædeflader samvirkende aftætningsflader er støbejernslegemets 3 elastisk eftergi velige kappe 4 vulstagtigt fortykket og bærer på begge sider en øverste elastisk tætningsstreng 5, som på sky-35 derens 1 smalsider 6 og nedefter går over i den nederste tætningsstreng 7.

The guide guides 8 covered by the sliding plates 10 arranged on both sides of the slider 10 reach only upwardly to the upper 5 sealing strings 5, since these sealing strings correspond to the outer contact of the slider 1. 2 outwardly grips the guide guides 8.

Den i højre halvdel af fig. 2 viste glideplade 10 er forsynet med imod skyderen afbøjede holdelister 11.The right half of FIG. 2, slide plate 10 shown is provided with retaining strips 11 deflected against the slider.

10 Disse holdelister 11 bærer forankringsgennembrydninger 12. Glidepladen 10 er sammen med begge holdelisterne 11 via en indvendig bagsprøjtning 13 og endvidere via en ydre omsprøjtning 14 af holdelisterne 11 fast indlejret i den elastisk eftergivelige kappe 4. Glidepladen 10 er også 15 forsynet med i sideretningen fremspringende forankringsaf-satse 15, som det fremgår af fig. 1. Endvidere bærer glidepladen 10 på sin mod skyderen anliggende inderside forankringsfremspring 16, med hvilke den fortandingsagtigt griber ind i det bagsprøjtede inderlag 13.These retaining strips 11 carry anchoring breakthroughs 12. The sliding plate 10, together with both the retaining strips 11, is permanently embedded in the elastically resilient sheath 4. The inner side of the retaining plate 10 is also provided with an lateral extension 14 of the retaining strips 11. anchoring ledge 15, as shown in FIG. 1. Furthermore, the slide plate 10 bears on its inner surface facing the slider anchorage protrusions 16, with which it gently engages the rear-sprung inner layer 13.

20 Ved det i venstre halvdel af fig.2* viste udførel seseksempel er begge ved den venstre smalside 6 af skyderen overfor hinanden liggende glideplader 10, som ligeledes bærer holdelister 11, sammenføjet af en forbindelsesbro 17 til et som en enhed udformet, U-formet glidepladepar 18.In the exemplary embodiment shown in the left half of FIG. 2, both on the left narrow side 6 of the slider, facing sliding plates 10, which also carry retaining strips 11, are joined together by a connecting bridge 17 to a unit-shaped U-shaped slide plate pairs 18.

25 Forbindelsesbroen 17 er ligeledes forsynet med forankringsgennembrydninger 19 og er via en indvendig bagsprøjtning 20 og en udvendig omsprøjtning 21 fast indlejret i den elastisk eftergivelige kappe 4. Glidepladeparret 18 er således også her i så høj grad af den elastomere kappe bagsprøjtet 30 og oversprøjtet, at kun den mod skyderventilhuset førte glideflade 22 bliver fri udadtil.The connecting bridge 17 is also provided with anchoring breakthroughs 19 and is permanently embedded in the resilient resilient jacket via an internal rear sprayer 20 and an external sprayer 21. The sliding plate pair 18 is thus also extruded so extensively by the elastomeric sheath 30 that only the sliding surface 22 sliding against the sliding valve housing is released externally.
