Description
gjennomgående hull, hvilket legeme ved økt vanntrykk sammentrykkes i aksiell retning hvori det gjennomgående hulls diameter minskes og derved struper strømmen. Imidlertid gir en slik anordning et høyt lydnivå som øker ved økende trykk og som heller ikke gir noen særlig konstant strøm. through hole, which body is compressed by increased water pressure in an axial direction in which the diameter of the through hole is reduced and thereby chokes the flow. However, such a device produces a high sound level which increases with increasing pressure and which also does not produce a particularly constant current.
Foreliggende oppfinnelse angår å fremskaffe en slik anordning som gir et lavere lydnivå som ikke forstyrrer omgivelsene og som ubetydelig endres med trykket, idet strømmen også kan holdes til-strekkelig konstant. Dette oppnås ifølge oppfinnelsen ved at legemet kjennetegnes av en eller flere i legemets mantelflate og/eller i ledningens indre periferi anbrakt i gjennomløpsrenner, hvis ender står i forbindelse med ledningens oppstrøms- respektiv nedstrømsender. The present invention relates to providing such a device which produces a lower sound level which does not disturb the surroundings and which changes insignificantly with the pressure, as the current can also be kept sufficiently constant. According to the invention, this is achieved by the body being characterized by one or more in the body's mantle surface and/or in the inner periphery of the line placed in through channels, the ends of which are in connection with the upstream and downstream end of the line.
Ifølge foretrukket utførelsesform løper rennen eller rennene skrueformet rundt legemet. According to the preferred embodiment, the channel or channels run helically around the body.
En foretrukket utførelsesform på oppfinnelsen'skal i A preferred embodiment of the invention shall i
det følgende beskrives nærmere under henvisning til tegningen som i lengdesnitt viser en anordning ifølge oppfinnelsen. the following is described in more detail with reference to the drawing which shows a device according to the invention in longitudinal section.
Anordningen består av fire til et hylsterformet legeme sammenskrudde deler, et hus 1, som i den ene enden er forsynt med et innvendig gjenget hull for tilkopling i en utløpsledning, et lokk 2, som er sammenskrudd med huset og som er forsynt med en innvendig gjenget tilkopling for en innløpsledning, en kanalinnsats 3 samt et dempe-legeme 4 som er innsatt i husets 1 hulrom. The device consists of four parts screwed together to form a sleeve-shaped body, a housing 1, which at one end is provided with an internally threaded hole for connection in an outlet line, a lid 2, which is screwed together with the housing and which is provided with an internally threaded connection for an inlet line, a channel insert 3 and a damping body 4 which is inserted in the housing 1 cavity.
Husets 1 indre hulhet avtar noe fra innløpsenden til utløpsenden og er i flaten forsynt med en skrueformet renne 5 me(i rektangulært tverrsnitt, som i flere omdreininger, her omtrent 3» strekker seg fra innløpsenden til utløpsenden i huset. I utløpsenden er hulheten forsynt med en anleggsskive 6 med mindre diameter enn husets utløp og som ved hjelp av tre eker 7 er forbundet med huset. Huset 1 er i innløpsenden forsynt med en utvendig gjenge på hvilken lokket 2 er påskrubart ved hjelp av en innvendig gjenge. Lokket 2 utvi-des traktformet fra innløpsenden og opptar i den utvidede koniske de-len mellom tilløpet og den innvendige gjengen kanalinnsatsen 3» som består av et i det vesentlige konisk legeme méd samme konisitet som lokket 2, men med mindre diameter, slik at det oppnås et mellomrom mellom innsatsen og lokket. På innsatsen er det anbrakt fire kammer 8 som holder innsatsen i avstand fra lokket, hvor det oppnås gjennom-løpskanaler for tilstrømming av vann fra innløpet til den skrueformede rennen 5 i huset. Innsatsen er også forsynt med et sentralt gjennomgående hull 9» samt på den mot huset vendte sideflaten med en sir- The inner cavity of the housing 1 decreases somewhat from the inlet end to the outlet end and is provided on the surface with a screw-shaped channel 5 m (in rectangular cross-section, which in several revolutions, here about 3" extends from the inlet end to the outlet end in the housing. At the outlet end, the cavity is provided with a mounting disk 6 with a smaller diameter than the housing's outlet and which is connected to the housing by means of three spokes 7. The housing 1 is provided at the inlet end with an external thread on which the lid 2 can be screwed on using an internal thread. The lid 2 expands funnel-shaped from the inlet end and accommodates in the extended conical part between the inlet and the internal thread the channel insert 3", which consists of an essentially conical body with the same conicity as the lid 2, but with a smaller diameter, so that a space is obtained between the insert and the lid. Four chambers 8 are placed on the insert which keep the insert at a distance from the lid, where through-flow channels are obtained for the flow of water from the inlet to the screw shaped gutter 5 in the house. The insert is also provided with a central through hole 9" and on the side facing the house with a circular
kulser renne 10. cools flow 10.
Inne i huset 1 er nå dempelegemet 4 tilpasset i tett anlegg mot husets innside som er forsynt med rennen 5. Dempelegemet, som er utført av elastisk materiale, f.eks. syntetisk gummi, har ve-sentlig begerform med relativt tykk, utover plan bunn som ligger an mot skiven 6 og en svak konisk vegg hvis ytre ende er nedført i den sirkulære rennen 10 i innsatsen. Inside the housing 1, the damping body 4 is now fitted in close contact with the inside of the housing, which is provided with the channel 5. The damping body, which is made of elastic material, e.g. synthetic rubber, has essentially a cup shape with a relatively thick, outwardly flat bottom that rests against the disk 6 and a weak conical wall whose outer end is lowered into the circular channel 10 in the insert.
Mellom planet mot hverandre stående flater på huset og lokket er det innsatt en 0-ring 11 av gummi for tetningens skyld. A rubber 0-ring 11 is inserted between the plane facing surfaces of the housing and the lid for the sake of sealing.
Alle detaljer foruten dempelegemet 4 og 0-ringen er hen-siktsmessig utført av plast, selv om andre materialer er tenkelige, All details apart from the damping body 4 and the 0-ring are appropriately made of plastic, although other materials are conceivable,
så som metall. Den skrueformede rennen 5 kan også strekke seg ned i dempelegemets utside eller være utført i helt og holdent i denne. such as metal. The screw-shaped channel 5 can also extend down into the outside of the damping body or be made entirely in it.
I stedet for en eller flere skrueformede renner er det også mulig å bruke en eller flere aksielt gående renner. Instead of one or more screw-shaped chutes, it is also possible to use one or more axially running chutes.
Når anordningen er i drift utsettes hullet 9 i kanalinnsatsen 3 for et væsketrykk som i det nærmeste er lik det dynamiske trykket i anordningens innløp. Dette førstnevnte trykk må være større enn trykket i rennen 5> da dempelegemets 4 vegg ellers ikke blir pres-set ned i rennen. Dersom trykket i innløpet og dermed i hullet 9 °g i dempelegemets hulrom synker, synker også trykket i rennen 5« Forskjellen mellom de lavere trykkene blir mindre enn forskjellen var mellom de høyere trykkene. Derved minskes innpressingen av dempelegemets vegg i rennen og rennens frie areal øker. På den måte kommer samme strøm til å slippes gjennom rennen som ved det høyere trykket og det mindre frie areal. When the device is in operation, the hole 9 in the channel insert 3 is exposed to a liquid pressure which is approximately equal to the dynamic pressure in the device's inlet. This first-mentioned pressure must be greater than the pressure in the chute 5> as otherwise the wall of the damping body 4 will not be pressed down into the chute. If the pressure in the inlet and thus in the hole 9 °g in the cavity of the damper body drops, the pressure in the channel also drops 5« The difference between the lower pressures becomes smaller than the difference was between the higher pressures. Thereby, the pressure of the damping body's wall in the gutter is reduced and the free area of the gutter increases. In that way, the same flow will be released through the chute as with the higher pressure and the smaller free area.
Rennens 5 tverrsnittsareal må alltid være mindre enn ledningens tverrsnittsareal dersom anordningen skal ha noen virkning. Forøvrig må arealene velges etter det trykkområde i hvilket anordningen skal arbeide. Rennens areal må også avpasses til rennens lengde, og dennes lengde bestemmes av den lyddemping som anordningen skal gi. Ved høye ledningstrykk gjøres rennen lsngre enn ved lave trykk. Ved den på tegningen viste utførelsesform er forholdene mellom ledningens og rennens arealer i størrelsesordenen 10:1. The cross-sectional area of the channel 5 must always be smaller than the cross-sectional area of the cable if the device is to have any effect. Otherwise, the areas must be selected according to the pressure range in which the device is to work. The area of the gutter must also be adapted to the length of the gutter, and its length is determined by the sound attenuation that the device must provide. At high line pressures, the channel is made smaller than at low pressures. In the embodiment shown in the drawing, the ratio between the areas of the line and the channel is in the order of 10:1.
