Description
Omstyringsventil. Bypass valve.
Nærværende oppfinnelse vedrører en omstyringsventil hvormed en fluidumstrøm og fortrinnsvis da en gasstrøm kan omsty-res. Ventilen ifølge oppfinnelsen kan med fordel anvendes for slike anlegg som f. eks. ekshaustoppvarmede dampkjeler ombord i fartøyer eller stasjonære anlegg. Særlig tar oppfinnelsen sikte på anvendelse for anlegg av den type hvor ekshaustgassen fra en eller flere forbrenningsmotorer ved hjelp av denne vekselventil valgfritt kan dirigeres til fri luft, eventuelt gjennom en lyddemper eller til en vannrørskjele for utnyttelse av ekshaustgassens varmeinn-hold. The present invention relates to a diverting valve with which a fluid flow and preferably a gas flow can be diverted. The valve according to the invention can be advantageously used for such systems as e.g. exhaust-heated steam boilers on board vessels or stationary installations. In particular, the invention aims at application for plants of the type where the exhaust gas from one or more internal combustion engines can optionally be directed to free air, possibly through a silencer or to a water-tube boiler for utilization of the heat content of the exhaust gas, by means of this diverter valve.
Ventilen ifølge oppfinnelsen er slik utformet at den tilveiebringer en hensikts-messig ledeflate for den gjennom ventilhuset strømmende ekshaustgass. Ventil-klappene kan videre uttaes uten å demon-tere de store exhaustrør. The valve according to the invention is designed in such a way that it provides an appropriate guide surface for the exhaust gas flowing through the valve housing. The valve flaps can also be removed without dismantling the large exhaust pipes.
Til bedre forståelse av oppfinnelsen skal denne beskrives nedenfor i detalj un-der henvisning til vedføyede tegning, hvor rent skjematisk er antydet et utførelses-eksempel ifølge oppfinnelsen. For a better understanding of the invention, it shall be described below in detail with reference to the attached drawing, in which a purely schematic example of an embodiment according to the invention is indicated.
Figuren viser som eksempel et ekshaustfyrt dampkjeleanlegg sett delvis i snitt, idet som nevnt kun de viktigste trekk er medtatt i denne skjematiske figuren, og alle i og for seg kjente og nødvendige organ som inngår i et slikt anlegg er utelatt for oversiktens skyld. The figure shows, as an example, an exhaust-fired steam boiler plant seen partially in section, as mentioned only the most important features are included in this schematic figure, and all known and necessary organs that are part of such a plant are omitted for the sake of overview.
Det på figuren viste anlegg består av vannrørskjele og en lyddemper anordnet for ved vekselventilen ifølge oppfinnelsen å kunne forbindes etter ønske med eks-haustgassavløpet fra fartøyets dieselmotor eller -motorer. Denne del av anlegget er med fordel anbragt i fartøyets skorsten eller overbygning. The system shown in the figure consists of a water tube boiler and a silencer arranged to be connected at the diverter valve according to the invention to the exhaust exhaust gas outlet from the vessel's diesel engine or engines. This part of the system is advantageously placed in the vessel's chimney or superstructure.
Ekshaustgassen fra fartøyets motor eller motorer føres inn i et ventilhus 2 gjennom en tilkoblingsflens 1. Fra ventilhuset 2 kan ekshaustgassen dirigeres som vist på figuren med de inntegnede piler The exhaust gas from the vessel's engine or engines is fed into a valve housing 2 through a connecting flange 1. From the valve housing 2, the exhaust gas can be directed as shown in the figure with the drawn arrows
gjennom et mellomstykke i form av et through an intermediate piece in the form of a
rørbend 4 og opp til en vannrørskjele 5, hvorfra ekshaustgassen avgår gjennom av-løpsrøret 6 til fartøyets skorsten. pipe bend 4 and up to a water pipe boiler 5, from which the exhaust gas leaves through the drain pipe 6 to the vessel's chimney.
Når omstyringsventilen innstilles i motsatt stilling slik at passasjen til vann-rørskjelen 5 avstenges, vil ekshaustgassen som tilføres ventilhuset 2 istedenfor gjennom forbindelsen 7 gå opp i lyddemperen 8 og derfra ut gjennom avløpsrøret 9 i far-tøyets skorsten. When the reversing valve is set in the opposite position so that the passage to the water-tube boiler 5 is closed off, the exhaust gas that is supplied to the valve housing 2 will instead go up through the connection 7 into the silencer 8 and from there out through the drain pipe 9 in the vessel's chimney.
Når vekselventilen innstilles i motsatt stilling, slik at passasjen til vannrørskje-len 5 avstenges, vil ekshaustgassen som til-føres ventilhuset 2 istedenfor å gå gjennom forbindelsen 4 gå opp i lyddemperen 8 og derfra ut gjennom avløpsrører 9 i fartøy-ets skorsten. Lyddemperen 8 kan være av vilkårlig valgt type, f. eks. den vanlige med skruespiralforløpende turbulens. When the diverter valve is set in the opposite position, so that the passage to the water-tube boiler 5 is shut off, the exhaust gas supplied to the valve housing 2 instead of going through connection 4 will go up into the silencer 8 and from there out through drain pipes 9 in the vessel's chimney. The silencer 8 can be of any chosen type, e.g. the usual one with helical turbulence.
For dirigering av ekshaustgasstrøm-men valgfritt til nevnte vannrørskjele 5 eller til lyddemperen 8, er der i ventilhuset 2 anordnet en spesiell omstyringsventil. Denne består av en arm 3 som er svingbart lagret om en aksel 33. Armen 3 kan ved passende betjeningsmidler (ikke vist) svinges mellom to ytterstillinger, i hvilke passasjen til henholdsvis kjele eller lyddemper avstenges. I den på figuren viste stilling er passasjen til lyddemperen avsteng, slik at alle ekshaustgasser passerer opp gjennom kjelen 5 og ut gjennom avløpet 6. For directing the exhaust gas flow - but optionally to said water tube boiler 5 or to the silencer 8 - a special diverting valve is arranged in the valve housing 2. This consists of an arm 3 which is pivotally mounted on a shaft 33. The arm 3 can be swung by suitable operating means (not shown) between two extreme positions, in which the passage to the boiler or silencer respectively is shut off. In the position shown in the figure, the passage to the silencer is closed, so that all exhaust gases pass up through the boiler 5 and out through the drain 6.
Selve ventillegemet omfatter ifølge oppfinnelsen to skålformede ventilskiver 30 festet dreibart om en sentral bolt e. 1. på armen 3 med de konkave sider vendende fra hverandre. Den ene eller annen av disse skålformede ventilskiver kan ved svingning av armen 3 bringes til å ligge an mot de ringformede seter 31 eller 32. Den ventil-skål som da ikke ligger an mot et ventilsete vil, som det tydelig sees av fig. 1, da tjene som meget gunstig ledeplate for gasstrøm-men gjennom ventilhuset 2. The valve body itself comprises, according to the invention, two bowl-shaped valve discs 30 fixed rotatably around a central bolt e. 1. on the arm 3 with the concave sides facing away from each other. One or the other of these cup-shaped valve discs can be brought to rest against the annular seats 31 or 32 by swinging the arm 3. The valve cup which then does not rest against a valve seat will, as can clearly be seen from fig. 1, then serve as a very favorable guide plate for gas flow - but through the valve body 2.
Ved at ventilskålene er dreibart lagret på armen 3, fortrinnsvis med en viss be-vegelsesfrihet også tvers på rotasjonsaksen, vil skålene alltid få godt anlegg mot resp. ventilsete. By the fact that the valve bowls are rotatably stored on the arm 3, preferably with a certain freedom of movement also across the axis of rotation, the bowls will always have good contact against or valve seat.
Ventilsetet mot lyddemperen 8 behø-ver ikke å være utformet annet enn som en rundtgående ringflens 32, mens derimot ringflensen 31' bør anordnes utskiftbar, slik at den kan utskiftes hvis tæringer fore-kommer og derved bevirker usikker tetning mot tilhørende ventilskive 30. Mot kjelen er det som nevnt av største betydning at ventilen gir helt sikker tetning. The valve seat against the silencer 8 does not need to be designed other than as a circumferential ring flange 32, while the ring flange 31', on the other hand, should be arranged replaceable, so that it can be replaced if corrosion occurs and thereby causes an insecure seal against the associated valve disk 30. Towards the boiler as mentioned, it is of the utmost importance that the valve provides a completely secure seal.
I forbindelsen mellom ventilhuset 2 og kjelen 5 inngår med fordel et mellomstykke i form av et rørbend 4. Rørbend 4 er forsynt med flenser i begge ender og kan således ved enkle midler taes ut av anlegget, hvorved man får fri adkomst til det indre av ventilhuset for ettersyn m. v. av vekselventilen. Samtidig fåes adgang til seteringen 31 som om nødvendig kan skif-tes ut eller slipes til, slik at det fåes effektiv tetning mellom denne og ventilskålen 30. The connection between the valve housing 2 and the boiler 5 advantageously includes an intermediate piece in the form of a pipe bend 4. The pipe bend 4 is equipped with flanges at both ends and can thus be taken out of the system by simple means, thereby gaining free access to the interior of the valve housing for inspection etc. of the diverter valve. At the same time, access is gained to the seat ring 31, which can be replaced or ground if necessary, so that an effective seal is obtained between this and the valve bowl 30.
Ventilen kan beveges med håndkraft eller mekanisk, f. eks. elektrisk. Ventilen kan på denne måte styres fra et passende sted, f. eks. fyrdørken. The valve can be moved by hand or mechanically, e.g. electric. In this way, the valve can be controlled from a suitable place, e.g. the lighthouse desert.
Ventilen ifølge oppfinnelsen er oven- The valve according to the invention is above-
for beskrevet i forbindelse med et ekshaustfyrt dampkjeleanlegg, men det vil umiddelbart forståes at den med fordel kan komme til anvendelse for en rekke andre anlegg hvor f. eks. en gass skal om-styres til den ene eller annen gasspassasje. Ved sin utformning gir den en gunstig ledeflate for de forbistrømmende gasser samtidig som den på en enkel, men effektiv måte sikrer god tetning og lett adkomst. as described in connection with an exhaust-fired steam boiler plant, but it will immediately be understood that it can be advantageously used for a number of other plants where, e.g. a gas must be diverted to one or another gas passage. Due to its design, it provides a favorable guiding surface for the passing gases while at the same time ensuring a good seal and easy access in a simple but effective way.
