Claims (10)

1. En metode til vedligeholdelse af en væskes gennemstrømningstryk ved et forudindstillet og næsten konstant niveau, der ikke afhænger af periodiske variationer i den mængde væske, der pumpes ind. Systemet omfatter mindst en trykakkumulator (6) og en dyseventil (1), som har et ventillegeme (2) og aksialt inde i dette en konisk nål (4) til åbning og lukning af udmundingen på udløbskanalen (8), og skaftet på nålen (4) styres af en glidende komponent (11) indsat i ventillegemet (2), og indstrømning ind i ventillegemet (2) kan passere til den anden side af den glidende komponent (11) gennem en eller flere kanaler (13), og nålen (4) bevæges aksialt i retning af åbning og lukning af ventilen (1) ved hjælp af de kræfter, der indvirker på den, og således justerer den tværsnittet af udløbskanalens (8) udmunding, kendetegnet ved trinene i påføring af pres på nålens (4) skaft via gennemstrømningstrykket (p1) sammen med en fjeder (5), så retningen af denne samlede kraft i alle situationer er opad, og det samlede tryk konstant holder enden af nålens (4) skaft presset mod tryk-akkumulatorens ventilskive (10), så denne åbnes, men denne kraft er altid mindre end den modsatte kraft, med hvilken akkumulatorens (6) forudkomprimerede gastryk (pO) påvirker ventilskiven (10), således at den ovennævnte samlede kraft, sammen med den kraft, gennemstrømningstrykket (p1) påfører ventilskiven (10), danner det første pres, som åbner udmundingskanalen (8) mod den anden og modsatte kraft, hvormed akkumulatorens (6) gastryk udøver pres mod ventilskiven (10). Når den første kraft som resultat heraf overstiger den anden kraft, begynder ventilskiven (10) og nålen (4), der er presset mod skiven, sammen at bevæge sig opad med det resultat, at trykket (p2) i akkumulatoren (6) stiger i overensstemmelse hermed og indstiller diameteren i udløbskanalens (8) udmunding og vinklen på nålens (4) koniske spids og tryk-akkumulatorens (6) volumen således, at ændringen i gas-volumen i akkumulatoren (6) forårsaget af nålens (4) bevægelse opad og den resulterende stigning i akkumulatorens tryk er lille selv ved maksimal gennemstrømning, med det resultat at forholdet mellem de ovennævnte kræfter automatisk justerer ventilens åbning, således at trykket i væskens gennemstrømning (p1) forbliver tæt på det oprindelige tryk (pO), der var forud-komprimeret i akkumulatoren (6), mens væskegennemstrømningen gennem udløbskanalen (8) til enhver tid fortsætter.
2. Metode i henhold til krav 1, kendetegnet ved at fjederkraften Fs, som løfter nålen (4) og presser dens skaft-ende mod ventilskiven (10), er lig med eller højere end den største af de kræfter, der er defineret i de følgende ligninger a og b: a) Fs = p2 A7 når nålen (4) er i den højeste funktionsstilling, som defineret af systemets maksimalt planlagte tryk b) Fs =ρθ A7 når nålen (4) lukker udløbskanalen (8); og i disse ligninger er A7 tværsnittet af nålens (4) hoved, vinkelret på dens akse ved kanalens (8) udmunding i driftssituationen.
3. Metode i henhold til krav 1 og 2, kendetegnet ved, at tryk-akkumulatoren (6) er en membran- eller ballon-akkumulator, og indersiden af membranen påvirkes af det oprindelige tryk (pO) i akkumulatoren (6) og ydersiden af membranen påvirkes af trykket i væskegennemstrømningen (p1), og herved bevæges membranen og den dertil fæstnede nål (4) som resultat af ændringer i væskegennemstrømningstrykket, mens de samtidig minimerer disse ændringer.
4. Metode i henhold til krav 1-3, kendetegnet ved, at når dyseventilen (1) benyttes til at vedligeholde trykket i et omvendt-osmose-system, indstilles det oprindelige tryk (pO) i akkumulatoren (6) højere end det osmotiske tryk fra det saltvand, der skal behandles.
5. Et arrangement til vedligeholdelse af væskegennemstrømningstryk i et system ved et for udindstillet og næsten konstant niveau, som ikke afhænger af periodiske variationer i en gennemstrømning, der pumpes ind i det. Systemet omfatter mindst en trykakkumulator (6) og en dyseventil (1), som har et ventillegeme (2) og deri aksialt en konisk nål (4) til åbning og lukning af udløbskanalens (8) udmunding, og nålens (4) skaft styres af en glide-komponent (11) fastgjort inde i ventillegemet (2), og gennemstrømningen ind i ventillegement (2) kan passere til den anden side af glide-komponenten gennem en eller flere kanaler (13), og nålen (4) er placeret til at kunne bevæge sig opad mod ventilens åbning og nedad på grund af de kræfter, der påvirker nålen (4), for at justere tværsnittet af udløbskanalens (8) mund, kendetegnet ved, at der til den øvre ende af ventillegemet (2), modsat udløbskanalen (8), er fastgjort en membran- eller ballon-akkumulator (6) med et for udindstillet oprindeligt gastryk (pO), og der mellem ventillegemet (2) og akkumulatoren (6) er udformet en kanal (9), gennem hvilken nålens (4) skaft-ende er anbragt til at udøve tryk på ventilskiven (10) i akkumulatoren (6) og til at bevæge sig sammen med den, således at det oprindelige tryk (pO) forårsager et nedadgående tryk, der vil lukke ventilen (1). Når ventillegemet (10) er i den nederste position og er understøttet af akkumulator-legemet (6), vil nålens (4) koniske spids lukke udmundingen på udløbskanalen (8), og den i systemet indpumpede gennemstrømning justeres til at påføre pres på ventilskiven (10) og nålen (4), som vil åbne ventilen, og en forudspændt fjeder (5) er anbragt til at påvirke nålen (4) med en fjederkraft (Fs), som forsøger at løfte nålen, og denne fjederkraft sammen med gennemstrømningskræfterne vil løfte ventilskiven (10) og nålen (4) mod den kraft, som det oprindelige tryk (pO) i akkumulatoren (6) påfører ventilskiven (10) for at åbne udløbskanalen (8) og på samme tid øge trykket i akkumulatoren (6) til det niveau (p2), der svarer til nålens (4) bevægelse opad. Diameteren af udløbskanalens (8) udmunding, vinklen på nålens (4) koniske spids og gas-volumen i akkumulatoren indstilles således, at ændringen i gas-volumen i akkumulatoren (6) forårsaget af nålens (4) bevægelse opad og den følgende stigning i trykket i akkumulatoren er lille selv med maksimal gennemstrømningsvolumen, med det resultat at tryk-akkumulatoren (6) justerer tværsnittet af udløbskanalens (8) udmunding og påvirker gennemstrømningstrykket (p1) i den væske, der flyder ud, og på denne måde holdes trykket i hele systemet tæt ved det forudindstillede oprindelige tryk (pO) i akkumulatoren (6).
6. Et arrangement i henhold til krav 5, kendetegnet ved, at den forudspændte fjeder (5) er en kompressions-fjeder, hvis ene ende understøttes af ventillegemet (2) eller glide-komponenten (11) og hvis anden ende understøttes af en udvidelse (12), som er udformet eller fastgjort på nålens (4) skaft, med det resultat at fjederens kraft (Fs), som vil løfte nålen (4), tillægges den kraft, som gennemstrømningstrykket (p1) udfører på nålen.
7. Et arrangement i henhold til krav 6, kendetegnet ved, at fjederkraften Fs, som løfter nålen (4), er lig med eller større end de største af de kræfter, der defineres i de følgende ligninger a og b: a) Fs = p2 A7 når nålen (4) er i den højeste driftsposition som defineret af systemets maksimalt planlagte tryk b) Fs = pO A7 når nålen (4) lukker udløbskanalen (8); og i disse ligninger er A7 tværsnittet af nålens (4) spids, vinkelret på dens akse ved kanalens (8) udmunding i den aktuelle driftssituation.
8. Et arrangement i henhold til krav 5-7, kendetegnet ved, at nålens (4) skattende er fastgjort til ventilskiven (10), som er fastgjort til membranen i membraneller ballon-akkumulatoren (6).
9. Et arrangement i henhold til krav 5-8, kendetegnet ved, at når dyseventilen (1) benyttes til at vedligeholde trykket i et omvendt-osmose-system, er det oprindelige tryk (pO) indstillet højere end det osmotiske tryk i det saltvand, der skal behandles.
10. Et arrangement i henhold til krav 5-9, kendetegnet ved, at dyseventilen (1) er en impulsturbine-ventil.
