Description

Foreliggende oppfinnelse angår en strupeanordnlng for rør ved et ventilasjonssystem, der rørets mantel er forsynt med hull som etter behov kan tillukkes for å oppnå struplngen. The present invention relates to a throttling device for pipes in a ventilation system, where the pipe's jacket is provided with holes that can be closed as needed to achieve the throttling.

Ved kjente strupeanordninger lukkes hullene på rørets mantel for oppnåelse av struplngen, f.eks. ved direkte å dekke over dem ved hjelp av et andre rør som etter behov trekkes over det første røret. Ettersom strupeanordningen i alminnelighet er beliggende i et lukket rom, må dette først åpnes, hvor-etter reguleringen av struplngen kan utføres. Dette er besværlig og krevende. Oppfinnelsen angår å fjerne de ovenfor nevnte ulempene. With known throttling devices, the holes on the tube's jacket are closed to achieve the throttling, e.g. by directly covering them by means of a second pipe which is drawn over the first pipe as necessary. As the throttling device is generally located in a closed room, this must first be opened, after which the regulation of the throttling can be carried out. This is difficult and demanding. The invention relates to removing the above-mentioned disadvantages.

Kjennetegnende for en strupeanordnlng ifølge oppfinnelsen er at den del av røret der hullene befinner seg utgjøres av flere etter hverandre beliggende rørstumper, som delvis overlapper hverandre slik at hullene i rørstykkene i den åpne stillingen ligger an mot hverandre og i den lukkede dreide stillingen ved siden av hverandre, hvorved hullene lukkes. A characteristic of a throat device according to the invention is that the part of the pipe where the holes are located is made up of several pipe stubs located one after the other, which partially overlap each other so that the holes in the pipe pieces in the open position lie against each other and in the closed turned position next to each other, whereby the holes are closed.

Ved hjelp av oppfinnelsen kan man utføre reguleringen av struplngen ved å dreie strupeanordningen fra dens ende, f.eks. ved hjelp av en liten elektrisk motor. Den elektriske motoren kan få en impuls, f.eks. fra en i et rom beliggende termostat som ved hjelp av i og for seg kjent teknikk bevirker impulser til den elektriske motoren. With the help of the invention, the regulation of the throttle can be carried out by turning the throttle device from its end, e.g. using a small electric motor. The electric motor can receive an impulse, e.g. from a thermostat located in a room which, using techniques known per se, causes impulses to the electric motor.

Kjennetegnende for en hensiktsmessig utførelsesform for oppfinnelsen er at rørstykket består av to forskjellige store, ved hverandre festede ringmanteldeler, der det ved begge finnes rundtgående hullrekker. A characteristic of a suitable embodiment of the invention is that the pipe piece consists of two different large ring jacket parts attached to each other, both of which have circular rows of holes.

Slike rørstykker er hensiktsmessig å fremstille f.eks. av plast, metall eller til og med keramikk, og det nødvendige antallet av dem kan lett monteres etter hverandre. Kjennetegnende for en annen hensiktsmessig utførelsesform for oppfinnelsen, er at rørstykkene er forsynt med et begrensningsorgan, såsom med en tapp eller skrue der det motsvarende stedet ved det motsatte rørstykket, såsom et hakk, tillater en bestemt liten dreiningsbevegelse mellom den åpne og den stengte stillingen. Således dreies rørstykkene i forhold til hverandre bare mellom den lukkede og den åpne stillingen, hvorved hele strupeanordningen er trinnløst regulerbar mellom den åpne og den lukkede stillingen. Dersom begrensningsorganet utgjøres av en skrue, kan en del av rørstykkene låses til hverandre, enten i en ønsket åpen, eller lukket stilling, hvorved de ikke kan dreies i forhold til hverandre. Such pipe pieces are suitable to produce e.g. of plastic, metal or even ceramic, and the required number of them can be easily assembled one after the other. Characteristic of another suitable embodiment of the invention is that the pipe pieces are provided with a limiting device, such as a pin or screw where the corresponding place at the opposite pipe piece, such as a notch, allows a certain small turning movement between the open and the closed position. Thus, the pipe pieces are rotated in relation to each other only between the closed and the open position, whereby the entire throat device is infinitely adjustable between the open and the closed position. If the limiting member consists of a screw, part of the pipe sections can be locked to each other, either in a desired open or closed position, whereby they cannot be rotated in relation to each other.

Oppfinnelsen skal i det følgende beskrives nærmere ved hjelp av et eksempel som er vist på tegningen. Fig. 1 viser strupeanordningen sett fra siden der et rør-stykke og endelokket er løsgjort fra strupeanordningen. Fig. 2 viser et tverrsnitt etter linjen II-II i fig. 1, og fig. 3 viser det samme som fig. 2, men i en annen, dvs. lukket stilling. In the following, the invention will be described in more detail using an example shown in the drawing. Fig. 1 shows the throat device seen from the side where a piece of pipe and the end cap have been detached from the throat device. Fig. 2 shows a cross-section along the line II-II in fig. 1, and fig. 3 shows the same as fig. 2, but in a different, i.e. closed, position.

Strupeanordningens rørparti der hullene 1 befinner seg, utgjøres av flere etter hverandre beliggende rørstykker 2 som delvis overlapper hverandre, slik at hullene 1 i rørstykkene 2 i den åpne stillingen ligger an mot hverandre (fig. 2), bg The pipe part of the throat device where the holes 1 are located is made up of several pipe pieces 2 located one after the other which partly overlap each other, so that the holes 1 in the pipe pieces 2 in the open position are abutting each other (fig. 2), bg

i den lukkede, dreide stillingen ved siden av hverandre, idet hullene lukkes (fig. 3). Rørstykket 2 består av to forskjellige store, til hverandre festede ringmanteldeler der det ved begge finnes rundtgående hullrekker 1. Rørstykkene 2 er forsynt med et begrensningsorgan, såsom en tapp 3, der det tilsvarende hakket 4 ved det motsatte rørstykket tillater en bestemt liten dreiningsbevegelse mellom den åpne og den lukkede stillingen. Strupeanordningens ende lukkes med lokket in the closed, rotated position next to each other, closing the holes (fig. 3). The pipe piece 2 consists of two different large ring jacket parts attached to each other, both of which have circular rows of holes 1. The pipe pieces 2 are provided with a limiting device, such as a pin 3, where the corresponding notch 4 on the opposite pipe piece allows a certain small turning movement between the open and the closed position. The end of the throat device is closed with the lid

5, til hvilket også motoren som regulerer strupeanordningen kan tilkoples for oppnåelse av dreiebevegelsen. Strupeanordningen er nærmest beregnet til å bli plassert i et lukket rom eller en kasse som kan fungere som trykksenkningskammer eller f ordelingskasse. 5, to which the motor which regulates the throttle device can also be connected to achieve the turning movement. The throat device is mostly intended to be placed in a closed room or a box that can function as a pressure reduction chamber or distribution box.

For en fagmann på området er det klart at oppfinnelsen ikke er begrenset til det ovenfor stående eksemplet, men kan varieres innen rammen for de etterfølgende patentkravene. For a person skilled in the field, it is clear that the invention is not limited to the above example, but can be varied within the scope of the subsequent patent claims.
