Description
Membrantilbakeslagsventil. Diaphragm check valve.
Oppfinnelsen vedrører en membrantilbakeslagsventil for væskeledninger, men også særlig for luft-, olje-, lut- og syreled-ninger. The invention relates to a membrane non-return valve for liquid lines, but also particularly for air, oil, lye and acid lines.
Tidligere kjente tilbakeslagsventiler utføres med kjegle eller kule som avstang-ningsorgan. Det har også vært foreslått hylseformige gummislangemembraner og lignende andre former som imidlertid alle krever et mere eller mindre komplisert ar-maturlegeme. Previously known non-return valves are made with a cone or ball as a stop device. Sleeve-shaped rubber hose membranes and similar other forms have also been proposed, which, however, all require a more or less complicated armature body.
Kravet til en tilbakeslagsventil, særlig for syre- og lutledninger, oppfylles i henhold til foreliggende oppfinnelse best ved hjelp av en spesielt formet forpresset, til-nærmelsesvis plan membran som er forsynt med kjente stoff innlegg og en spesiell leppe som er utført uten innlegg og derfor er smi-dig. Med en slik membran arbeider mem-brantilbakeslagventilen absolutt pålitelig både for syre- og lutledninger og også for vann-, luft- og oljeledninger. Den stilling hvori ventilen anbringes kan være vilkårlig, hvilket er en videre fordel ved oppfinnelsen, da lukkevirkningen er like god i hver stilling og uavhengig av tilbakestrømningen. The requirement for a non-return valve, particularly for acid and caustic lines, is best met according to the present invention by means of a specially shaped pre-pressed, approximately flat membrane which is provided with known fabric inserts and a special lip which is made without inserts and therefore is smi-dig. With such a membrane, the membrane check valve works absolutely reliably both for acid and lye lines and also for water, air and oil lines. The position in which the valve is placed can be arbitrary, which is a further advantage of the invention, as the closing effect is equally good in each position and independent of the return flow.
Ved anvendelse av tilbakeslagsmembra-nen i rørledninger med stor diameter kan membranen forsynes med steg, hvorved man får forskjelligartede åpninger, som visl i fig. 3—5. Med disse steg hindres i hvert tilfelle en utrivning av membranen ved plutselig opptredende høyt tilbakestrøm-ningstrykk. When using the non-return membrane in pipelines with a large diameter, the membrane can be provided with steps, whereby various openings are obtained, as shown in fig. 3-5. With these steps, a tearing of the membrane is prevented in each case in the event of a suddenly occurring high backflow pressure.
Som hus anvendes helt normale han-delsvanlige membranavstengningshus. Den allerede beskrevne myke leppe av tilbake-slagsmembranen ligger i hvilestilling an mot husets midtsteg som strekker seg over husets hele bredde, mens membranen ved gjennomstrømning av et medium alt etter gjennomstrømningsmengden løftes mere eller mindre og frigir gjennomstrømningen. As a housing, completely normal commercial membrane shut-off housings are used. The already described soft lip of the rebound membrane rests against the middle step of the housing, which extends over the entire width of the housing, while the membrane, depending on the amount of flow, is lifted more or less during the flow of a medium and releases the flow.
Ved tilbakestrømmende medium blir leppen alt etter tilbakestrømningstrykket trukket In the case of backflowing medium, the lip is pulled according to the backflow pressure
fast mot husets midtsteg, så at en tilbake-strømning av mediet med sikkerhet hindres. firmly against the middle step of the housing, so that a backflow of the medium is safely prevented.
Fig. 1 viser med pilen gjennomstrøm-ningsretningen av det strømmende medium som alt etter gjennomstrømningsmengden løfter membranen 3 med leppen 2 fra husets steg 4, så langt at fri gjennomstrøm-ning av mediet uten stort trykktap i hvert tilfelle sikres. Fig. 1 shows with the arrow the flow direction of the flowing medium which, depending on the amount of flow, lifts the membrane 3 with the lip 2 from the step 4 of the housing, so far that free flow of the medium without major pressure loss is ensured in each case.
Ved den allerede nevnte anvendelse av helt normale hus for membranavsteng-ningsventiler oppnås ikke bare en vesentlig billigere utførelse, men dessuten blir det mulig fra enhver membranavstengnings-ventil bare ved innsetting av en tilbake-slagsmembran i henhold til oppfinnelsen og påsetting av et plant eller hvelvet deksel, å fremstille en tilbakeslagsmembranventil, hvor et av glass fremstilt eller et som ram-me med vindu utført deksel gjør det mulig at tilbakeslagsmembranventilen kan anvendes som kontrollinstrument . Fjærvirkningen av den forpressede membran 3 gjør at membranen naturlig sø-ker å legge seg på husmidtsteget, hvorved ved tilbakestrømmende medium der inntrer tetning over stegets hele bredde. With the already mentioned use of completely normal housings for diaphragm shut-off valves, not only is a significantly cheaper design achieved, but also it becomes possible from any diaphragm shut-off valve only by inserting a non-return diaphragm according to the invention and putting on a flat or vaulted cover, to produce a non-return membrane valve, where a cover made of glass or a window-like frame makes it possible for the non-return membrane valve to be used as a control instrument. The spring effect of the pre-pressed membrane 3 means that the membrane naturally seeks to lay itself on the center step of the housing, whereby in the case of a backflowing medium, sealing occurs over the entire width of the step.
Fig. 2—5 viser forskjellig formede steg som gir sikkerhet særlig ved stor membran-diameter og/eller høye tilbakestrømnings-trykk, og gir forskjellige gjennomstrøm-ningsåpninger som tilpases vedkommende Fig. 2-5 show differently shaped steps which provide safety in particular with large membrane diameters and/or high backflow pressures, and provide different flow openings which are adapted to the person concerned
