Description
Anordning ved sugerør. Device by straw.
Sugeror, -slanger, tåtesmokker etc. har den mangel at de ikke tilpasser seg tilstandene på bnsket måte. Således vil f.eks. Suckers, hoses, pacifiers etc. have the disadvantage that they do not adapt to the conditions in the desired way. Thus, e.g.
et sugeror ikke hindre væske i å renne ut av beholderen når denne snus på hodet, og.en tåtesmokk på flaske for spebarn har en tendens til å bli flat på grunn av undertrykket som dannes i flasken eftersom næringsmidlet suges ut. Derved stanses tilfbr-selen. I romfart oppstår særlige problemer i forbindelse med inntagelse av flytende fode. I rommet kan man ikke oppbevare væske i åpne beholderen. Det er imidlertid ikke praktisk å anvende vanlige sugeror, da disse lett kan slippe væske ut i utide. a straw does not prevent liquid from flowing out of the container when it is turned upside down, and a pacifier in a bottle for infants tends to become flat due to the negative pressure created in the bottle as the food is sucked out. This stops the supply line. In space travel, special problems arise in connection with the ingestion of liquid food. Liquids cannot be stored in the open container in the room. However, it is not practical to use ordinary straws, as these can easily release liquid prematurely.
Formålet med oppfinnelsen er å tilveiebringe en anordning ved sugeror som på den ene side gir åpen forbindelse når man suger i den ene ende og dessuten sperrer når det dannes overtrykk ved den andre ende, slik at væske ikke kan presses igjennom sugeroret, men som på den annen side f.eks. slipper luft inn for utligning av trykkforskjell når det dannes undertrykk, f.eks. på grunn av at det suges væske ut av beholderen. The purpose of the invention is to provide a device for a straw which, on the one hand, provides an open connection when sucking at one end and also blocks when overpressure is formed at the other end, so that liquid cannot be forced through the straw, but as on the other side e.g. lets air in to equalize the pressure difference when negative pressure is created, e.g. due to liquid being sucked out of the container.
Dette oppnås ifolge oppfinnelsen ved en ventilanordning ved sugeror, kjennetegnet ved at den omfatter to stempler som er innbyrdes mekanisk forbundet på en slik måte at når stemplene utsettes for trykkvariasjoner i endene av sugeroret, vil et undertrykk i den ene rorende medfore at det tilhorende stempel bevirker åpning av ventilanordningen. This is achieved according to the invention by a valve device at a suction pipe, characterized by the fact that it comprises two pistons which are mechanically connected to each other in such a way that when the pistons are exposed to pressure variations at the ends of the suction pipe, a negative pressure in one of the moving parts will cause the corresponding piston to cause opening of the valve device.
Det er således tilveiebragt en anordning ved sugeror som åpner når det dannes undertrykk ved en av åpningene, men som sperrer når det dannes overtrykk ved en av åpningene. Anordningen virker således som en toveis gjennornstromningsventil hvis funk-sjon er uavhengig av trykkgradientens fortegn. A device has thus been provided for a suction pipe which opens when a negative pressure is formed at one of the openings, but which blocks when an overpressure is formed at one of the openings. The device thus acts as a two-way recirculation valve whose function is independent of the sign of the pressure gradient.
Anordningen muliggjor at man kan suge på vanlig måte, mens den automatisk sperrer hvis væsken av en eller annen grunn begynner å stromme av seg selv gjennom sugeroret. The device makes it possible to suck in the usual way, while it automatically blocks if the liquid for some reason starts to flow by itself through the suction tube.
En slik anordning innbygget f.eks. i en tåtesmokk muliggjor at undertrykk i tåteflasken automatisk utlignes straks sugingen opphorer, hvorved sugingen kan gjenopptas efter kort tid uten ytter-ligere foranstaltninger. Such a device built in e.g. in a pacifier makes it possible for negative pressure in the baby bottle to be automatically equalized as soon as suction stops, whereby suction can be resumed after a short time without further measures.
Ved å anvende en anordning ifolge oppfinnelsen på bokser med leskedrikk, vil man hindre at små barn kan bli kvalt på grunn av for stor tilforsel av væske. By applying a device according to the invention to cans of soft drinks, it will be prevented that small children can suffocate due to excessive supply of liquid.
Anvendelsesområdene for anordningen ifolge oppfinnelsen er mang-foldige. Det kan dreie seg om såvel daglig husholdning, syke- The areas of application for the device according to the invention are manifold. It can be about both daily housekeeping, sick
og barnepleie, industri, laboratorier etc. and childcare, industry, laboratories etc.
Oppfinnelsen skal belyses nærmere ved den efterfblgende be-skrivelse av et utfbrelseseksempel skjematisk vist på den ved-fbyede tegning. The invention shall be elucidated in more detail by the following description of an exemplary embodiment schematically shown in the attached drawing.
På tegningen er 1 en del av et sugeror som er forbundet med et ventilhus 2. Dette er utformet med et sentralt kammer 10 på hver side av hvilket er et ventilsete 7a resp. 7b. Mot disse virker ventillegemer 16a resp. 16b. Disse ventillegemer er utformet med armer 17 som forlbper parallelt og er fortannet. Mellom armene og i inngrep med fortanningen er anordnet et tann-hjul 18. Ved denne anordning er således stemplene 16a og 16b tvangsstyrt slik at de beveger seg samtidig mot eller fra sine respektive ventilseter. Med 8 betegnes en kanal for utligning av mulig trykkforskjell mellom kammeret 9 og atmosfæren. In the drawing, 1 is part of a suction pipe which is connected to a valve housing 2. This is designed with a central chamber 10 on each side of which is a valve seat 7a or 7b. Against these, valve bodies 16a or 16b. These valve bodies are designed with arms 17 which run parallel and are toothed. A toothed wheel 18 is arranged between the arms and in engagement with the toothing. With this arrangement, the pistons 16a and 16b are thus forcibly controlled so that they move simultaneously towards or from their respective valve seats. 8 denotes a channel for equalizing the possible pressure difference between the chamber 9 and the atmosphere.
Anordningen virker som folger: Når det f.eks. i seksjonen la oppstår en trykkreduksjon på grunn av sug, vil trykkforskjellen mellom rbrseksjonen la og kammeret 10 bevirke at stemplet 16b presses vekk fra sitt ventilsete 7b. Derved skyves samtidig stemplet 16a vekk fra sitt ventilsete 7a, hvorved anordningen åpner for gjennomstrømning av et fluidum fra rbrseksjonen lb til seksjonen la som en folge av den trykkforskjell mellom rbrseksjonene som er en forutsetning for en fluidumstrbmning. Når sug ved rbrseksjonen la opphorer, vil fluidumstrbmmen automatisk bevirke at stemplet 16a på grunn av strbmningsmotstanden presses til anlegg mot ventilsetet 7a og anordningen sperrer. Hvis derimot det ved rbrseksjonen lb er frembragt et undetrykk som er en folge av sug gjennom roret fra én beholder tilkoblet rbrseksjonen lb, vil stemplet 16a etter at sug opphorer ved rbrseksjonen la automatisk bevirke at stemplet 16a på grunn av trykkgradienten skyves vekk fra ventilsetet, hvorved ventilen åpner og en fluidumstrbm, f.eks. luftstrbm, kan flyte fra rbrseksjonen la til rbrseksjonen lb for utligning av trykkforskjellen. En slik utligning av trykkforskjellen er f.eks. meget bnskelig ved tåteflasker, hvor det, eftersom innholdet suges ut av flasken, er nbdvendig med tilfbrsel av luft for å kompen-sere det undertrykk som oppstår i flasken ved utsugning av innholdet. The device works as follows: When it e.g. in section la a pressure reduction occurs due to suction, the pressure difference between rbrsection la and chamber 10 will cause the piston 16b to be pushed away from its valve seat 7b. At the same time, the piston 16a is pushed away from its valve seat 7a, whereby the device opens for the flow of a fluid from the tube section lb to the section la as a result of the pressure difference between the tube sections which is a prerequisite for a fluid flow. When suction at the tube section ceases, the fluid flow will automatically cause the piston 16a due to the flow resistance to be pressed against the valve seat 7a and the device blocks. If, on the other hand, a negative pressure is produced at rbrsection lb which is a consequence of suction through the tube from one container connected to rbrsection lb, after suction ceases at rbrsection la, the piston 16a will automatically cause the piston 16a to be pushed away from the valve seat due to the pressure gradient, whereby the valve opens and a fluid flow, e.g. air stream, can flow from pipe section la to pipe section lb to equalize the pressure difference. Such an equalization of the pressure difference is e.g. very desirable with baby bottles, where, since the contents are sucked out of the bottle, it is necessary to supply air to compensate for the negative pressure that occurs in the bottle when the contents are sucked out.
Ventilens symmetriske oppbygning bevirker at åpning resp. sper-ring av ventilen er uavhengig av trykkgradientens fortegn. The valve's symmetrical structure means that opening or blocking of the valve is independent of the sign of the pressure gradient.
Den ovenfor beskrevne ventil kan anvendes for ethvert fluidum. Den kan modifiseres på mange måter innenfor rammen av kravene, idet forbindelsen mellom de to stempler kan utfores på andre måter enn den viste og beskrevne, likesåvel som ventilhuset kan gis modifiserte utforelser. Ventilene kan fremstilles av hen-siktsmessig materiale, og egner seg bl.a. for masseproduksjon av plast, glass e.l. The valve described above can be used for any fluid. It can be modified in many ways within the scope of the requirements, as the connection between the two pistons can be made in other ways than the one shown and described, just as the valve housing can be given modified designs. The valves can be made of suitable material, and are suitable for example for mass production of plastic, glass etc.
