Description
Qverstrømningsventil for høytrykkspumpeanlegg. Qcross-flow valve for high-pressure pumping systems.
Ved høytrykkspumpeanlegg er det vanlig å anordne i mateledningen en sik-kerhetsventil som tilsvarer et overtrykk og som ved utillatelig trykkstigning åpner seg og fører trykket tilbake til normaltrykk i mateledningen. Disse overtrykksventiler svikter imidlertid der hvor høytrykksan-legget benytter sentrifugalpumpe, da det høyeste trykk ved slike pumper er fastlagt ved pumpekarakteristikken og som regel tilsvarer det tillatte matetrykk. Hvis en slik pumpe arbeider mot en i høytrykks-ledningen anordnet og lukket sleide, oppstår det foran sleiden et trykk som på grunn av sentrifugalpumpens flate karak-teristikk bare er uvesentlig høyere enn driftstrykket, slik at overtrykksventilen reagerer dårlig eller bare utilstrekkelig. Denne utillatelige arbeidsmåte for overtrykksventilen oppstår særlig når motor og pumpe løper med fullt omdreiningstall, slik som det er vanlig ved brannsluknings-apparater. In high-pressure pumping systems, it is common to arrange a safety valve in the supply line which corresponds to an overpressure and which, in the event of an inadmissible increase in pressure, opens and brings the pressure back to normal pressure in the supply line. However, these pressure relief valves fail where the high-pressure system uses a centrifugal pump, as the highest pressure in such pumps is determined by the pump characteristic and usually corresponds to the permitted feed pressure. If such a pump works against a slide arranged in the high-pressure line and closed, a pressure occurs in front of the slide which, due to the centrifugal pump's flat characteristics, is only insignificantly higher than the operating pressure, so that the pressure relief valve reacts poorly or simply insufficiently. This impermissible way of working for the overpressure valve occurs in particular when the engine and pump are running at full speed, as is common with fire extinguishers.
Den gjennom pumpen tilførte, sam-lede energi omsettes da i varme, som kan føre til en utillatelig temperaturstigning av den væske som skal befordres og også av pumpen. Ved sentrifugalpumper som arbeider med minsket ledning (inntil 30— 35 % av normalledningen) kan der også opptre svingefenomener som følge av det ustabile område ved små gj ennomstrøm-ningsmengder. The total energy supplied through the pump is then converted into heat, which can lead to an unacceptable rise in temperature of the liquid to be conveyed and also of the pump. In the case of centrifugal pumps that work with a reduced line (up to 30-35% of the normal line), oscillation phenomena can also occur as a result of the unstable area at small flow rates.
Oppfinnelsen angår en ny utforming av en overstrømsventil i et høytrykks-pumpeanlegg, som ikke er mer enn vanlig trykkavhengig, men som er avhengig av gjennomstrømningsmengden i mateledningen og som holder den væskemengde som gjennomstrømmer pumpen uforandret eller på et innstillbart minimum som elimi-nerer de ovenfor nevnte vanskeligheter. Dette oppnås i følge oppfinnelsen ved at en overstrømsventil som styres av trykket i et i mateledningen innkoblet Venturirør, er ensidig belastet med en innstillbar fjær. The invention relates to a new design of an overflow valve in a high-pressure pump system, which is not more dependent on pressure than usual, but which is dependent on the flow rate in the supply line and which keeps the amount of liquid flowing through the pump unchanged or at an adjustable minimum which eliminates the above mentioned difficulties. According to the invention, this is achieved by an overflow valve which is controlled by the pressure in a Venturi pipe connected to the supply line, and is loaded on one side with an adjustable spring.
Den nye- utforming skal i form av ut-førelseseksempler forklares nærmere under henvisning til den skjematiske tegning. The new design shall be explained in more detail in the form of design examples with reference to the schematic drawing.
Ved utførelsene ifølge fig. 1 er i mateledningen 1 innlagt et Venturirør 2 fra hvis trangeste sted en avgreningsledning 3 går ut. I materetningen foran Venturi-røret er avgrenset en utløpsstuss 4 hvis utløp 5 overvåkes av en ventilskive 6. Ventilskiven 6 er ved hjelp av en stempelstang forbundet med to stempler 8, 9 i sylinder-husene 10, 11. De to sylinderhus 10, 11 står i åpen forbindelse med hverandre, idet huset 11 på den ene side av stemplet 9 er forbundet med avgreningsledningen 3 og på den annen side med en parallelledning 12 som går ut fra mateledningen foran Venturirøret 2. Stemplet 9 er på undersiden belastet med en fjær 13 som tjener til vekt-utligning. In the embodiments according to fig. 1, a Venturi tube 2 is inserted in the supply line 1, from whose narrowest point a branch line 3 exits. In the feed direction in front of the Venturi tube, an outlet nozzle 4 is defined whose outlet 5 is monitored by a valve disc 6. The valve disc 6 is connected by means of a piston rod to two pistons 8, 9 in the cylinder housings 10, 11. The two cylinder housings 10, 11 stand in open connection with each other, the housing 11 on one side of the piston 9 being connected to the branch line 3 and on the other side to a parallel line 12 that exits from the feed line in front of the Venturi tube 2. The piston 9 is loaded on the underside with a spring 13 which serves for weight compensation.
Ved egnet dimensjonering av ventilskiven 6, stemplene 8, 9 og fjæren 13 kan oppnås at ved sperring av mateledningen eller ved den strupning bak Venturirøret 2, flyter der over ventilskiven og utløpsled-ningen 4, i alle fall ut en minste væskemengde som gjennomstrømmer pumpen og som er tilstrekkelig til å utelukke en utillatelig oppvarming av væsken og pumpen. Blir derimot strupingen minsket og kom-mer strømningen i hovedledningen igjen i gang, så gjennomstrømmes Venturirøret 2. Det innstiller seg under stemplet 9 som følge av forbindelsen med Venturirørets trangeste sted på grunn av arbeidstrykket, et mindre trykk i forhold til trykket i ledningen 12, slik at stemplet 9 mer eller mindre beveges nedover og derved mer eller mindre resp. helt lukker gjennomgan-gen over ventilskiven 6. By suitable dimensioning of the valve disk 6, the pistons 8, 9 and the spring 13, it can be achieved that in the event of blockage of the supply line or in the case of a bottleneck behind the Venturi tube 2, at least a minimum amount of liquid flows out over the valve disk and the outlet line 4, which flows through the pump and which is sufficient to exclude an inadmissible heating of the liquid and the pump. If, on the other hand, the throttling is reduced and the flow in the main line starts again, then the flow through the Venturi tube 2. It settles under the piston 9 as a result of the connection with the narrowest place of the Venturi tube due to the working pressure, a lower pressure in relation to the pressure in the line 12, so that the piston 9 is more or less moved downwards and thereby more or less resp. completely closes the passage above the valve disc 6.
Ved utformingen ifølge fig. 2 er stus-sens 4 utløp 5 styrt av en ringsleid 14 som er forbundet med stemplet 9. Ringsleiden 14 er således formet at den ved bevegelse oppover lukker utløpet 5. I ledningen 3 er en strupeventil 15 innkoblet ved hvis hjelp der i ledningen 3 kan dannes en øket strømningsmotstand for å oppnå at stemplet 9 arbeider bløtere. Dimensjoneringen er foretatt således at ved manglende strøm-ning eller ved bare liten strømning i Ven-turirøret, frigir ringsleiden 14 utløpet 5 mer eller mindre, således at ved økende strømning d. v. s. uttak fra mateledningen ved Venturirørets arbeidstrykk avlaster oversiden av stemplet 9 som derved går i øvre endestilling, i hvilken ringsleiden 14 lukker utløpet 5. In the design according to fig. 2, the outlet 5 of the nozzle 4 is controlled by an annular slide 14 which is connected to the piston 9. The annular slide 14 is shaped in such a way that it closes the outlet 5 when it moves upwards. an increased flow resistance is formed to achieve that the piston 9 works more smoothly. The dimensioning has been done so that in the event of no flow or only a small flow in the Venturi tube, the ring slide 14 releases the outlet 5 more or less, so that with increasing flow, i.e. withdrawal from the feed line, the working pressure of the Venturi tube relieves the upper side of the piston 9, which thereby goes into upper end position, in which the ring slide 14 closes the outlet 5.
Også her kan stemplet 9 for innregu-lering. belastes med en innstillbar fjær 16. Here too, the piston 9 can be used for adjustment. is loaded with an adjustable spring 16.
Ifølge fig. 3 er stemplet 9 erstattet med en membran 9 a og utløpet 5 er overvåket According to fig. 3, the piston 9 is replaced with a membrane 9 a and the outlet 5 is monitored
av en dobbeltventil 17 som er koblet til membranen 9 a ved hjelp av stangen 7. Arbeidsmåten for denne utforming tilsvarer arbeidsmåten i fig. 2, idet en inn-regulering skjer ved hjelp av en innstillbar belastningsfjær 16. of a double valve 17 which is connected to the membrane 9 a by means of the rod 7. The working method for this design corresponds to the working method in fig. 2, as an adjustment takes place by means of an adjustable load spring 16.
