DIAPHRAGM-OPERATED MULTIPLE WAY VALVE

The invention concerns a memhranbetätigtes multiple way valve with a housing, in which a step drill is trained as the default of a majority of radial sealing surfaces, with an adjusting link shiftable in the step drill, which a Versehlußstück co-operating with two of the radial sealing surfaces in the Gegentakt carries, and with on an end of the adjusting link s a put on and diaphragm specified at the edge at the housing, which appropriately forms together with a final section of the step drill over a Impulsleitung by external excitation over a Magnetventäl operatable valve engine and yield a angefernten hub section has, which co-operates with its radial front surface as the further endplate with a further radial sealing surface of the step drill and which sits a Durchffangsbohrung strömunffsmitteldicht on lo the final section of the adjusting link. With one from the FR-PS Nr.2.103.982 MehrweEevent31 of this kind admitted the adjusting link only from the lV/embranen is led. Ur guidance of the Verstellgiiedes only a Rinffansatz of the diaphragm relatively thin at the housing more clamped, is consulted. Such a guidance is not sufficient for some applications, with which it depends on particularly accurate opening and closing of the valve IS. The invention is therefore the basis the task to create a multiple way valve einffangs of the kind mentioned which possesses an improved guidance of the valve adjusting link. This task is solved according to invention thereby that the Nabenabschrätt of the diaphragm exhibits one rafllal mobile lip seal and over these current on the wall of a guidance section of the step drill runs. In this way also the relatively thick hub section of the diaphragm is consulted for the guidance of the Verstellgüedes, so that the diaphragm in two axially lying one behind the other places at the housing is led, i.e. with its clamped Rihgansatz and with their portion of the hub section containing the Lippendlchtung, so that also for the adjusting link a safe guidance results. By the erfindungsgeraäße training of the multiple way valve 2s still another further substantial advantage is obtained, i.e. that too the two sides of the lip seal of lying ranges of the step drill are flowmoderately from each other separate, so that can be subjected the Impulsledtung turned range, which is limited finallaterally by the inside of the actual diaphragm, always with the same pressure, appropriately with atmospheric pressure. Hiedurch becomes the SteUkraft independently of the position of the Ventilachiebers, which during the arrangement after the FR-PS Nr.2.103.982 the case is not, since the entire inside of the diaphragm is located here in flow connection for actual valve drilling, in which the pressure as a function of the position of the adjusting link varies. A Ausführungsheispie! the invention now on the basis the only figure one describes, which an axial profile by a memhranbetätigtes Ylehrwegeventil shows in accordance with the invention. 3s the represented diaphragm-operated Mehrwegeventll --11--, which possesses a rechteckförmigen cross section, a multipart housing points --12-- up, at its a narrow side --13-- Tapped holes --14, 16 and 17-- for the compresser air bleed port --P-- and/or the exhausts --R and S-- and at its opposite narrow side --21-- Thread high run gene --18 and 19-- for the connection of two consumers --A and/or B--. Depending upon position of a Verstellgiiedes --22--, that in a raehrstufigen axial, centric Steuerbohrunff --23-- in the housing --12-- , is either, as represented in Fig.1, the compresser air bleed port is axially adjustable --P-- with the consumer --B-- and the consumers --A-- with the exhaust --R-- connected and the exhaust --S-- locked, or the compresser air bleed port --P-- is with the consumer --A-- and the consumers --B-- with the exhaust --S-- connected and the exhaust --R-- locked. The adjusting link --22--, itself with its 4s the end at one into the tax drilling --23-- locking plugs --26-- stored compression spring --27-- falls, is by a diaphragm unverschiehbar connected with its other end --28-- against the effect of the compression spring --27-- axially adjustably. The adjusting link --22-- and/or lVIembran --28-- become indirect by on the top side --29-- the housing --12-- put on and fastened electromagnetic drive --31--, represented by that only the housing, an execution o and means of mounting are operated. The diaphragm --28-- possesses at an upper range a ring beginning --32--, whose is held between two Gehäuseteilen thickened extent-lateral end positively. The ring beginning --32-- it can be either in such a manner flexibly ductile that this deformation with moving the diaphragm --28-- from Nr.361264 of its Ruhesteliung downward constantly it comes, or however in such a way that the ring beginning --32-- with this movement, that causes a detent effect the movement of the diaphragm --28-- for instance after the half way in this direction supports. In a middle range is the diaphragm --28-- with a radial close: lip --33-- provided, itself to the wall range concerned of the multi-level tax drilling --23-- sealing puts on. The diaphragm --28-- an axial, circular sealing surface furthermore possesses --34--, itself the switched on condition of the valve not represented in the design --1t-- to a first valve seat --36-- puts on, which at the transition of the bleed bore --16-- to one with the consumer drilling --18-- in connection standing annular space --37-- is arranged. Within the range of the annular space --37-- is the adjusting link --22-- with a cross hole --35-- provided. At the transition of this annular space --37-- to one with the supply drilling --14-- connected second annular space --38-- is a second valve seat --39-- planned, to that the one more ringoder tellerförmige sealing rim --41-- a double seat endplate --42-- in the represented state of rest of the valve --11-- sealing fits. The double seat endplate --42--, which is designed as sealing ring, “a further more ringoder teUerförmige sealing rim points at its other axial end --43-- up, those concerning the transverse centre plane! 5 mirror-image to the sealing rim --41-- is arranged. The two sealing rims --41 and 43-- are by an outer circumference groove wedge-shaped in the undeformed condition: - 4 4-- in the sealing ring --42-- separated and take according to the wedge-shaped groove --44-- to their outer edge constantly off. Their parallel exterior surfaces at the sealing rims --41, 43-- run in undeformed condition perpendicularly to the longitudinal axle center and close of the interior drilling possess one small enular groove each. The double seat sealing ring --42-- is between two at the adjusting link --22-- fastened disks --46-- gotten jammed and thus at the adjusting link --22-- both axially and radially unbewegbar held. The sealing ring --42-- consists either of plastic with rubber-similar characteristics or of rubber. The material and the thickness of the sealing rims --41, 43-- it is in such a way selected that itself the sealing rims --41, 43-- with setting on the Ventflsitz concerned --39, 47-- flexibly deform, like this on the basis the Dichtllppe --41-- and the 2s Ventflsitzes --39-- is represented. The reason of the extent groove --44-- thereby a substantially smaller diameter than it assigned second and/or third valve seat possesses --39, 47--. Thereby it is possible that itself the sealing rims --41, 43-- into the opening within the circular valve seat --39 and/or 47-- to at least partly draw in it leaves whereby they put on themselves under pre-loading at the valve seat concerned. This creation of the sealing rims to the valve seat is still strengthened thereby that it of the annular space --38-- ago are subjected to compressed air. Independently of Herstellungstolermlzen and such, which arise with the manipulation, the gasket with each of its sealing rims has a always safe plant at the valve seat concerned. The third circular valve seat --47-- rises up at a housing-firm projection/lead into the second annular space --38-- and limits between itself a third annular space --48--, that with the Verbraucher3s drilling --19-- in connection is located. At height of the third annular space --48-- the adjusting link possesses --22-- a Verdickung --49--, those over its extent distributes with several axially going through slots --51-- is provided. In the represented state of rest of the valve --11-- flows thus compressed air of the Zuführbohrnng --14-- by the second annular space --38--, the slots --51-- and the third annular space --48-- to the consumer drilling --19--, during the second annular space --38-- because of the sealing plant of the first sealing rim --41-- at the second valve seat --39-- no connection to the other consumer drilling --18-- possesses. At the lower end the third annular space --48-- is the third Ventflsitz --47-- turned away a fourth circular valve seat --52-- planned, at a sealing ring -53-- in resting position of the valve --11-- just as the sealing rim --41am second valve seat --39-- under the effect of the compression spring --27-- hermetically fits. The sealing ring --53-- is in a groove of a 4S of ring federation --54-- let in, with that itself the adjusting link --22-- at the compression spring --27-- supports. Between dern ring federation --54-- and the wall of the tax drilling --23-- a fourth annular space exists - 56--, into that the bleed bore --17-- flows. Becomes now on the basis of the represented rest position the adjusting link --22-- toward the arrow D moves downward, then the axial Diehtfläche puts --34-- the diaphragm --28-- to the first so valve seat --36-- and the second Diehtlippe --43-- the double seat endplate --42-- to the third valve seat --47-- hermetically on. The second sealing rim --43-- can thereby, as of its Ventflsitz --39-- becoming released sealing rim --41-- in the starting situation, into the opening between the circular valve seat ù47-- are pulled in. After this movement also the sealing ring has --53-- the fourth valve seat Nr.361264 ù52-- released, so that, as dash-dotted by arrows suggested, a compressed air connection of the supply drilling --14-- by the annular spaces --38 and 37-- and/or the cross hole--35-- to the consumer drilling --18-- and an exhaust way of the consumer drilling --19-- by the annular spaces --48 and 56-- to the bleed bore --17-- exists. The sealing plant of the sealing elements to the valve seats concerned effected in this condition under the effect one of an actuator of herrührsnden pressure, and so it is enough as this continues, according to which the adjusting link --22-- by the compression spring --27-- into his initial position again one zurüekbewegt. As actuator that becomes the inlet bore --14-- supplied working medium, here for example compressed air, uses. In addition is the supply drilling --14-- over a close offable I0 Impulsleitung or - channel --59-- with one in the housing --12-- arranged Steuerraum --67-- over the diaphragm --28-- connected. The Impulsleitung --59-- goes from a small drilling --61-- in a place of the range of the supply drilling --14-- out and over not represented flows, in the housing --12-- arranged channels or drillings in a further drilling --62-- and a cone-shaped mouthpiece arranged directed upward in the longitudinal axle center --63-- into a coaxial Saeklochbohrung --64--, those of the top side --29-- the housing --12-- ago is trained and the NIagnetantrieb --31-- faces. Eccentrically to the mouthpiece --63-- flows at the reason of the blind hole drilling --ü4-- to the circular Steuerraum --67-- prominent further channel --ö6-- the Impulsleitung --59--. In the blind hole drilling --64-- is a piston-like Verschlußorgan --68-- axially adjustably and over an O-ring --70-- sealing stored, that with the single solenoid valve --31-- in effect connection and from this is propelled. In a state of rest the piston preserves --68--, for example under the effect of one in the single solenoid valve --31-- arranged compression spring centrically closely at the opening of the mouthpiece --63-- on, so that of the supply drilling --14-- by the Impu] sleitung --59-- 2um Steuerraum --67-- no compressed air control pulse to arrive can. Becomes the reversal the electromagnetic drive --31-- operates, then his anchor pulls to the pistons --68-- toward the arrow C upward, so that it itself of the mouthpiece --63-- takes off. Thus compressed air of the supply drilling becomes --14-- by the not represented channels, the mouthpiece --63--, the area --69-- between the reason of the blind hole drilling --64-- and the pistons --68-- by the channel --66-- the Impu] sleitung --59-- into the Steuerraum --67-- pressed, so that itself the diaphragm --28-- and thus the adjusting link --22-- under effect of compressed air toward the arrow D moves downward. Becomes the magnet --31-- des-activate, then the piston becomes --68-- again sealing against the mouthpiece --63-- pressed, so that at the diaphragm --28-- no more pressure is applied and the adjusting link --22-- itself under effect of the compression spring --27-- into his starting position to again upward move can. At the reason of the blind hole drilling --64-- is at that the channel --66-- turned away side a recess --71-- planned, into the one radial drilling --72-- flows. Into the radial drilling --72--, which reaches up to the exterior, is a pin --73-- unverschiebbar, however swivelling and by an O-ring sealing stored. The pin --73-- points into the recess --71-- meeting abgeflaehtes end trained as eccentric cams --74-- up. The end --74-- it is so far, preferably up to the longitudinal centre plane flattened that it straight into the recess --71--, which possesses a circular ground, fits. In a state of rest the even, flattened surface of the end preserves --74-- the piston --68-- opposite. Is for example the electromagnetic drive --31-- defectively, so that the piston --68-- not to be operated and the entire valve could --11-- would fallow-lie, then the piston can --68-- by hand thereby to be raised by the pin --73-- from the outside by means of a screwdriver plug-in into its operating slot turned vird, whereby the flattened end --74-- with its circular extent at the piston --68-- to the plant comes and this to raise can. As soon as the piston --68-- something is raised, can compressed air by the Irish Republican Army pulse line --59-- flow and the valve --11-- operate in managing descriptive way. It understands itself that as working medium and/or or tax medium can find another gaseous medium which is at pressure or also a liquid medium use instead of compressed air also. Furthermore it is possible, closing the Impuisleitung off --59-- also in other way for example by a flap operatable by an air pulse od.dgl to cause. It is to be recognized thus that with the valve according to invention the diaphragm --28-- several functions exercises: On the one hand it serves the valve stem for the drive --22--, which the Verste] iglied, at the same time takes it represents x6 at the guidance of the Verstellglledes in the range in the locating hole --23-- part, moreover the diaphragm practices --28-- the function of a Innendiehtung out, as is to be recognized with xl, since it surrounds the adjusting spindle from the outside sealing and at this from the outside ago sealing on] puts, in addition it serves x2 within the range as seat face with the axially working disc seat --34 to 36--, beyond that it serves x3 with the lip as radially mobile and between adjusting link and locating hole sealing lip seal within the range --33, 34-- and finally it works as clamped diaphragm in the well-known way. With the preferential execution form bent in the design the electromagnet serves the invention for the Fremdbetätlgung of the valve stem --31--. The diaphragm is finally still with one to a certain extent as supporting disk serving StabilisierungsI0 ring --60-- provided, which lends stop to the diaphragm with its various functions. This stabilization ring, which can be consisted e.g. of metal and trained fit with springs-flexibly can, is at that the Impulsleitung turned side and can appropriately be connected with the diaphragm by curing.
