Description

Blendenregulierschieber Aperture control slider

Die vorliegende Erfindung betrifft einen Blendën regulierschieber zur DurchfhiBregelung von flüs.sigen, k & rnigen Oder gasfdrmigen Medien. Bei verschiede nen Medlien stellt sich das Problem, aufeinander gleitende Organe der Reguliervorrichtung und die Blendenelemente gegen allmâhliche Verschmutzung zu schützen, die schliefich so weit gehen kann, dal die Reguliermë>glichkeiten eingeengt od'er überhaupt jede Regulierbewegung verunmbglicht wird. Da die Blen denelemente von Blendenschiebern ganz bestimmte Bewegungen ausführen müssen, besonders wenn sie in Biner Ebene liegen und sich nur mit den Schmal seiten berilhren, bedarf es je mindestens Biner genauen Führung für jedes Blendenelement und, aul3erdem je mi.nde,stens Bines Mitnehmers für jedes Blendenele ment. Es sind daher an vielen Stellen ineinandergrei fende erhühte und vertiefte Teile vorhanden, wo durch allmâhliche Verunreinigungen Stdrungen entstehen künnen, wenn nicht GegenmaBnah:men getroffen werden. The present invention relates to an orifice regulating slide for regulating the flow of liquid, grainy or gaseous media. With various media, the problem arises of protecting the organs of the regulating device sliding on one another and the diaphragm elements against gradual contamination, which can eventually go so far that the possibilities for regulation are restricted or any regulation movement is rendered impossible at all. Since the diaphragm elements of diaphragm slides have to perform very specific movements, especially if they are in a plane and only touch with the narrow sides, at least two precise guides are required for each diaphragm element and, moreover, at least one driver for each diaphragm each aperture element. There are therefore interlocking raised and lowered portions in many places where gradual contamination may cause interference unless countermeasures are taken.

Bei bekannten Blendenschiebern, wobei die Blen denelemente mittels ineinandergreifender erhdhter un.d vertiefter, nutenartiger Teile geführt und angetrie ben werden, sind nur ungenügende oder zu umstând lichen Konstruktionen führende MaBnahmen getrof fen worden. Beim Blendenregulierschieber gemâl3 der Erfindung wird, nun dén erwâhnten Schwierigketen mit Erfolg dadurch begegnet, da(3 aile erwâhnten ver tieften Teile auf ih@rer eanzen Lânge gleiches Profil aufweisen und beidseitig frei in -qohlrâume münden, derart, daB sich in den vertieften Ireilen ansammeinde Verunreini;gungen durch die erhühten Teile beidseitig durch die En.den der vertieften Teile in die erwâhnten Hohlrâume ausgestoBen werden kônnen. In the case of known aperture slides, in which the aperture elements are guided and driven by means of interlocking raised and recessed, groove-like parts, only insufficient measures have been taken or measures which have led to cumbersome constructions. With the aperture control slide according to the invention, the difficulties mentioned are successfully countered by the fact that all the recessed parts mentioned have the same profile over their entire length and open out freely into hollow spaces on both sides, such that the recessed parts accumulate Impurities from the raised portions may be expelled through the ends of the recessed portions into the cavities mentioned on both sides.

Ein, Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, welche in Fig. 1 einen Querschnitt und in An embodiment of the invention is shown in the drawing, which in Fig. 1 shows a cross section and in

Fig. 2 einen Lângsschnntt nach Linie 11-1I in Fig. 1 durch d'en Blendenschieber zeigt. Figure 2 shows a longitudinal section taken along line II-II in Figure 1 through the diaphragm shutter.

Der Blendenremiierschie@ber ist in einem Gehâuse 1 mit Deckel 2 gekapselt und kann mit den Stutzen 3 und 4 in Bine Rohrleitung eirngebaut werden, deren Durchflul3 zu regeln i'st. Deckel und Gehliuse weisen je Bine, in montiertern Zustande einander zugekehrte ebene Dichtungsflâche 5 bzw. 6 auf, zwischen wel chen Flâchen die sich nur lângs der Schmalseiten be rührenden, im wesentlichen dreieckigen Bl@endenele mente 7 in die innerhalb der Dichtungsfl,âchen@ gebil dete, sechseckige Rebgulierôffnung 8 (Fig. 1) ragen. Diese echseckige Regul'iërdffnung lâuft beidseitig in Bine kreisrunde ôffnung aus, die je an einen der Stut zen 3 bzw. 4 anschlief3t. Die Dichtungsflâchen 5 und 6 sind mit zwekreisfdrmigen Fangnuten 9 versehen. The diaphragm stop slide is encapsulated in a housing 1 with a cover 2 and can be built into a pipeline with the sockets 3 and 4, the flow rate of which is to be regulated. Cover and housing each bin, in the assembled state, have flat sealing surfaces 5 and 6 facing one another, between which surfaces the essentially triangular diaphragm elements 7, which touch only along the narrow sides, fit into the surfaces formed within the sealing surfaces closed, hexagonal regulative opening 8 (Fig. 1). This hexagonal regulating opening ends in a circular opening on both sides, which connects to one of the sockets 3 and 4 respectively. The sealing surfaces 5 and 6 are provided with bicircular retaining grooves 9.

Die Blendenelemente 7 sind an den beiden, einen Winkel von 60 einschl'ief3enden Schmalseiten, die mit benachbarten Elementen in Berührung stehen, je mit viner entsprechend konvex bzw. konkav gew & lb ten Mâche verschen. Diesse Flâchen greifen ineinander und argeben so einen guten gegenseitigen Halt der Bl'endenelemente und Bine gute Dichtung der Fugen zwischen benachbarten Elementen. An d'en vorderen Ecken der Elemente 7 .sind scharfe Kanten 10 gebil det, die béi der gegenseitigen Verschiebung der Ele mente auf der Schmalseite des benachbarten Elemen tes abgleiten und diese Schmalseite reinigen. Damit wird einerseits vermieden, da13 die Elemente durch zwischen sie gelangende Verunreinigungen, insbeson dere Faserstoffe, zu klemmen beginnen und zugleich voneinander abgehoben werden und schlecht zu d'i.ch ten beginnen. The screen elements 7 are on the two narrow sides, which enclose an angle of 60° and which are in contact with adjacent elements, each with a correspondingly convex or concave curved shape. These surfaces interlock, providing good mutual retention of the screen members and good sealing of the joints between adjacent members. Sharp edges 10 are formed at the front corners of the elements 7, which slide off the narrow side of the adjacent element when the elements move relative to one another and clean this narrow side. On the one hand, this avoids the elements beginning to jam due to dirt getting between them, in particular fibrous materials, and at the same time being lifted from one another and beginning to fit poorly.

AuBerhalb der Dichtungsflâchen 5 und 6 sind aile Blendenelémente 7 einseitig mit Biner Mitnehmer rolle 11 versehen. Die Rollen 11 greifen in gekrümmte Mitnehmernuten 12 Bines Regulierringes 13, wel'cher auf Biner Schulter 14 des Gehâuses 1 drehbar ge- lagert ist. Die Nuten 12 .sied durchgehend gefrâst, das hei8t, sie laufen mit unverminderter Weite bis an die Innen- und AuBenflâchen des Regulierringes, wo- bei die âuBeren Nutenenden in einen Ringraum 15 des Gehâuses 1 münden. Die erwâhnte Lagerschuiter 14 für den Regulierring 13 weist geringere axiale Breite auf, als die Tiefe der Nuten 12 betrâgt, so da13 sich in den Nuten 12 ansammelnde feste. Oder faserige Stoffe durch die in den Nuten 12 laufenden Rollen 11 beidseitig in den Raum 15 ausgestol3en werden kdn- nen und daher die Nuten 12 automatisch stets sauber gehalten werden und Hemmungen der Regulierbewe- gungen nicht vorkommen kônnen. Um das AusstoBen nach innen zu erleichtern, sind an den inneren Enden der Nuten 12 flache Quernuten 12' eingefrâst, deren scharfe AuBenkanten 12" auch als Abstreifer zur Rei- nigung der Lagerschulter 14 wirken. Wâren dagegen die Mitnehmernuten 12 nicht durch:gehend- offen, wie es bei bekannten Schiebern oft der Fall ist, so kijnn- ten in den Nuten sich sammelnde Feststoffe durch die hin und her gehendë Relativbewegung der Rollen 11 in den Nuten 12 langsam an die Nutenenden gescho- ben werden, wo sie schlieBlich zu festen Pfropfen zu- sammengedrückt werden und die voue Regulierbewe- gung hindern. In diesem Falle gab es oft keinen an- deren Ausweg mehr, als den Schieber auszubauen, zu dffnen und gründlich zu reinigen. Es kdnnten übrigens am Lagerkdrper des Regulierringes auch Lüeken vorgesehen sein, welche immer dann die inneren Enden der Nuten 12 vollstândig freigeben, wenn die Rollen 11 bei ganz geschlossenem Schieber in ihre innerste Stellung gelangen. Outside the sealing surfaces 5 and 6, all screen elements 7 are provided with a carrier roller 11 on one side. The rollers 11 engage in curved driving grooves 12 in a regulating ring 13 which is rotatably mounted on a shoulder 14 of the housing 1 . The grooves 12 are milled continuously, that is, they run with an undiminished width up to the inner and outer surfaces of the regulating ring, with the outer ends of the groove opening into an annular space 15 of the housing 1 . The aforementioned bearing protector 14 for the regulating ring 13 has a smaller axial width than the depth of the grooves 12, so that solids accumulate in the grooves 12. Or fibrous substances can be ejected on both sides into the space 15 by the rollers 11 running in the grooves 12 and therefore the grooves 12 are automatically kept clean at all times and inhibitions of the regulating movements cannot occur. In order to facilitate inward ejection, flat transverse grooves 12' are milled into the inner ends of the grooves 12, the sharp outer edges 12" of which also act as scrapers for cleaning the bearing shoulder 14. If, on the other hand, the driver grooves 12 were not continuously open As is often the case with known slide valves, solids accumulating in the grooves could be slowly pushed to the groove ends by the reciprocating relative movement of the rollers 11 in the grooves 12, where they finally form solid plugs be pressed together and prevent the full regulating movement. In this case there was often no other way out than to remove the slide, open it and clean it thoroughly. Incidentally, there could also be gaps on the bearing body of the regulating ring, which fully release the inner ends of the grooves 12 whenever the rollers 11 reach their innermost position with the slide fully closed.

An der den Rollen 11 gegenüberliegenden Seite der Blendenelemente 7 sind im wesentlichen recht- eckige Führungskldtze 18 befestigt, die in gerade Nuten 19 des Gehâusedeckels 2 eingreifen und in diesen verschiebbar sind. Diese Nuten 19 durchbre- chen die Wand 20 volistândig und stehen -daher mit einem Ringraum 21 des Deckels 2 in Verbindung, und sie laufen auch nach'beid'en Seiten jebis an die âul3ere Begrenzungsflâche 22 d ier Wandung 20, wie Fig. 1 in punktierten Linien andeutet. Diese Nuten 19 werden daher durch d e praktisch spielfrei in ihnen geführten Klôtze 18 stets sauber nach beiden Seiten ausgesto- Ben, und eventuelle Feststoffe werden ohne Schwie- rigkeiten entweder radial nach auBen in den Ring raum 15 Oder aber seiflich in den Ringraum 21 aus- gestol3en. Eine Verklemmung oder Hemmung der Führungskldtze 18 in ihren Nuten 19 ist daher auch praktisch ausgescblossen. Substantially rectangular guide blocks 18 are fastened to the side of the screen elements 7 opposite the rollers 11, which engage in straight grooves 19 of the housing cover 2 and can be displaced therein. These grooves 19 completely break through the wall 20 and are therefore in connection with an annular space 21 of the cover 2, and they also run on both sides up to the outer boundary surface 22 of the wall 20, as shown in FIG indicated by dotted lines. These grooves 19 are therefore always cleanly ejected to both sides by the blocks 18 guided in them with practically no play, and any solids are ejected without difficulty either radially outwards into the annular space 15 or laterally into the annular space 21 . A jamming or obstruction of the guide pads 18 in their grooves 19 is therefore also practically ruled out.

Schlieffllich RTI ID="0002.0275" WI="4" HE="3" LX="530" LY="2310"> ist durch die beiden VerschluBschrau- ben 23 (Fig. 1) die M6glichkeit gegeben, die mitein- and'er kommunizierenden Hohlrâume des Gehâuses . und Deckels grândlich durchzuspülen. Eine solche Durchspülung bedingt keinen Betriebsunterbruch, trotzdem die Dichtungsflâchen 5 und 6 nicht in der Lage sied, ein allmâhliches Durchsickern der Flüs- sigkeit in :die Hohlrâume zu verhindern. Die Undich- tigkeit ist jedoch so gering, da13 beim Durchspülen keine unzulâssig starke Durchmischung des Nutzflus- ses und des Spülwasserflusses zu befürchten ist. Finally, the two locking screws 23 (FIG. 1) make it possible to he communicating cavities of the housing. and lids to be rinsed thoroughly. Such flushing does not cause any interruption in operation, although the sealing surfaces 5 and 6 are not able to prevent a gradual seepage of the liquid into the cavities. However, the leakage is so slight that there is no risk of an impermissibly strong mixing of the useful flow and the flushing water flow during flushing.

Die Ringnuten 9 sind normalerweise nicha mit Dichtungsringen ausgestattet. Es hat sich gezeigt, daB an den Dichtungsflâchen durchtretende Verunreini- gungen, insbesondere Fasermaterial, sich in diesen Nuten anlagert und schlief'ich selbst Bine filzartige Dichtungseinlage bildet, die das Durebtreten von Fasermaterial zum Reguliermechanismu.s wirksam beschrânkt. The ring grooves 9 are normally not equipped with sealing rings. It has been shown that contamination, particularly fibrous material, penetrating the sealing surfaces accumulates in these grooves and ultimately forms a felt-like sealing insert which effectively limits the passage of fibrous material to the regulating mechanism.

Am Regulierring 13 sind zwischen den Mitneh- mernuten 12 gerade Nuten 14 eingearbeitet, die Ver- unreinigungen von den Seitenflâchen der Blendenele- men@te abstreifen und abführen und somit zusâtzlich zur Sel!bstreinigung des Schiebers beitragen. Straight grooves 14 are worked into the regulating ring 13 between the driver grooves 12, which scrape and remove dirt from the side surfaces of the screen elements and thus also contribute to the self-cleaning of the slider.

Die Regulierung erfolgt durch Drehen Biner Spindel 25, die mittels Biner Mutter 26 einen am Regulierring vorgesehenen Hebel 27 und damit den Regulierring selbst :dreht. Die Verschiebung Bines mit der Mutter 26 verbundenen Zeigers 28 kann durch ein Sichtfen- ster 29 des Spindelgehâu,ses beobachtet und die Regu- lierstellung auf Biner auf der Geh'âuseaugen:seite an- gebracbten Skala abgelesen werden. Der Regulier- ring nimmt bei seiner Drehung die in seine Nuten grefenden Rollen 11 mit, wobei die Blendenelemente lângs dér Nuten 19 verschoben werden. Dabei gleiten ihre Schmalseiten in der erwâhnten Weise aufeinander ab, wobei die verbleibende DurchtluBôffnung, die stets polygonale Form aufweist, je nach der radialen Lage :der Elemente 7 verschieden groB ist. Der Blen- denregulierschieber kann mit beliebig vielen Blenden- elementen geba:ut werden, wodurcb sich Bine viel- eckige Durchflul3dffnung mit entsprechend vielen Sei- ten ergibt. Regulation is effected by turning a spindle 25 which, by means of a nut 26, rotates a lever 27 provided on the regulation ring and thus the regulation ring itself. The displacement of the pointer 28 connected to the nut 26 can be observed through a window 29 of the spindle housing and the regulation position can be read on the scale attached to the housing eyelet side. During its rotation, the regulating ring takes with it the rollers 11 that engage in its grooves, with the shutter elements being displaced along the grooves 19 . In the process, their narrow sides slide off one another in the manner mentioned, with the remaining through-opening, which always has a polygonal shape, varying in size depending on the radial position of the elements 7 . The diaphragm control slide can be built with any number of diaphragm elements, resulting in a polygonal flow opening with a corresponding number of sides.

Die Ringnuten 9 der Dichtungsflâchen 5 und 6 haben auBer der oben erwâhnten Wirkung auch den zusâtzlichen Vorteil, da13 ihre Kanten Verunreinigun- gen von den liber sie bewegten Seitenflâchen der Blendenelemente 7 abstreifen. Um schlieBlich auch die Selbstreinigung der Dichtungsflâchen 5 und 6 sel'bst zu verbessern, k & nnten auch die Seitenflâchen d'er Blendenelemente mit Abstreifnuten versehen wer- den, die natürlich so verlaufen müi3ten, da13 die Dicht- heit nicht unzulâssig leide.t. Eine sehr zuverlâssige Dichtung ist aber ohnehin nicht erforderlich, weil die auBerhalb der Dichtungsflâchen 5 und 6 liegenden Hohlrâume des Gehâuses und Deckels an sich wie- <RTI ID="0002.0543" WI="10" HE="4" LX="1153" LY="2148"> derum nach auBen vollstândig abgedichtet sind. The annular grooves 9 of the sealing surfaces 5 and 6 have, in addition to the above-mentioned effect, the additional advantage that their edges wipe off dirt from the side surfaces of the diaphragm elements 7 moving over them. Finally, in order to improve the self-cleaning of the sealing surfaces 5 and 6 themselves, the side surfaces of the panel elements could also be provided with wiper grooves, which of course would have to run in such a way that the tightness would not suffer unacceptably. However, a very reliable seal is not required in any case, because the cavities of the housing and cover lying outside the sealing surfaces 5 and 6 are like- <RTI ID="0002.0543" WI="10" HE="4" LX="1153" LY="2148"> which are completely sealed off from the outside.
