DK 1543 1 7 BDK 1543 1 7 B
Den foreliggende opfindelse angår fordelings- eller samlingsrør i ventilationskanaler, hvor røret i længeretningen er delt i rørhalvdele med afgrenede åbninger i den ene rørhalvdel, med hvilke den anden rørhalvdel er aftageligt forbundet for rengøring og inspektion.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to distribution or assembly pipes in ventilation ducts, wherein the pipe is longitudinally divided into pipe halves with branched openings in one pipe half with which the other pipe half is removably connected for cleaning and inspection.
5 I ventilationsanlæg er fordelings- eller samlingskasser sædvanligt forekommende med henblik på at føre flere kanaler sammen til en kanal. Ifølge kendt teknik udføres kasserne rektangulære med aftagelige låg til rensning, regulering og inspektion. De ulemper, som følger med denne teknik, er dels turbulent strømning, der forårsager støj og høje tryk-10 fald, og dels urationel fremstilling på grund af stort dimensionssorti-ment.5 In ventilation systems, distribution or collection boxes are usually present in order to bring several channels together into one channel. According to the prior art, the boxes are made rectangular with removable lids for cleaning, regulation and inspection. The disadvantages associated with this technique are partly turbulent flow causing noise and high pressure drops, and partly unreasonable production due to large dimensional range.
Fra britisk patent nr. 2 018 379 kendes et rør, som er .delt i længderetningen, og hvor rørhalvdelene kan sættes sammen og sammenholdes ved hjælp af Z-formede klemmeorganer, som muliggør adskillelse af rør-15 halvdelene, når det ønskes. Den ene rørhalvdel er her forsynet med en rørafgreningsåbning af mindre dimension end selve røret i. lighed med det, der forekommer i fordelings- eller samlingsrør i ventilationskana ler. Ved således at anvende denne kendte teknik, nemlig et rør deleligt på langs med op til flere afgreningsrør, opnås et fordelings- eller sam-20 lingsrør, hvor de ovennævnte ulemper vedrørende turbulent strømning, som forårsager støj og høje trykfald, er fjernet.British Patent No. 2,018,379 discloses a longitudinally divided tube in which the tube halves can be assembled and held together by Z-shaped clamping means which permit separation of the tube halves when desired. Here, one half of the pipe is provided with a pipe branch opening of smaller dimension than the pipe itself, similar to that which occurs in distribution or assembly pipes in ventilation ducts. Thus, using this known technique, namely a pipe divisible longitudinally up to several branch pipes, a distribution or assembly pipe is obtained in which the above-mentioned disadvantages of turbulent flow, which cause noise and high pressure drops, are removed.
Ifølge kendt teknik er indreguleringsorganer til indregulering af luftstrømmen gennem afgreningsrørene arrangeret i selve afgreningsåb-ningen. Ved inspektion og rengøring af fordelings- eller samlingsrøret 25 fjernes således den ene rørhalvdel, hvorefter eventuelt indregulerings-aggregaterne må svinges til åben stilling eller fjernes for adgang til afgreni ngsrørene/kanalerne.According to the prior art, regulating means for regulating the air flow through the branch pipes are arranged in the branch opening itself. Thus, upon inspection and cleaning of the distribution or manifold 25, one pipe half is removed, after which the balancing assemblies may have to be swung to the open position or removed for access to the branches / ducts.
Efter den nævnte inspektion og kanal rengøring bringes indregule-ringsaggregaterne tilbage på plads i afgreningsåbningerne og den nævnte 30 rørhalvdel kobles sammen med den anden rørhalvdel for at lukke fordelings- eller samlingsrøret. Derefter må indreguleringsaggregaterne justeres på ny for at opnå de ønskede gennemstrømningsforhold i de forskellige kanaler, som er tilkoblet fordelings- eller samlingsrøret, dvs. samlingskassen.After said inspection and duct cleaning, the balancing assemblies are brought back into place in the branch openings and the said pipe half is coupled to the other pipe half to close the distribution or assembly pipe. Thereafter, the balancing units must be re-adjusted to achieve the desired flow conditions in the various ducts connected to the distribution or connecting pipe, ie. collection box.
35 Formålet med den foreliggende opfindelse er at tilvejebringe et fordelings- eller samlingsrør af den indledningsvis angivne art, hvor indregul eringsorganerne under inspektion og eventuel rengøring ikke påvirkes, og hvor disse sammen med den aftagelige rørhalvdel kan bringes 2The object of the present invention is to provide a distribution or assembly pipe of the type indicated in the preamble, where the control means during inspection and possible cleaning are not affected and where these can be brought together with the removable pipe half 2.

tilbage på plads med indreguleringsorganerne i den oprindeligt indstillede stilling, således at en ny, tidskrævende indregulering ikke er nødvendig.back in place with the adjusting means in the initially set position so that a new, time-consuming adjustment is not necessary.
Dette opnås ifølge opfindelsen ved de i krav 1 angivne ejendomme-5 ligheder.This is achieved according to the invention by the properties of claim 1.
Ved at indreguleringsorganerne er fastgjort på aksler, der strækker sig igennem den aftagelige rørhalvdels væg og er rørformet, kan en trykmåling udføres ved hjælp af den rørformede aksel ved indregulering af indreguleringsorganet.By fixing the balancing means on shafts extending through the wall of the removable tube half and being tubular, a pressure measurement can be performed by means of the tubular shaft by balancing the balancing means.
10 Ved at indregu!eringsorganerne er pladeformede som angivet i krav 3, og forskydeligt indstillelige i de tilhørende afgreningsåbningers ak-sialretning, opnås et fordelagtigt symmetrisk lufthastighedsbi Ilede omkring det pladeformede indreguleringsorgan, når dette skydes aksielt i forhold til kanal åbningen, og dermed nedsat luftstrømningsstøj.By means of the locking means being plate-shaped as claimed in claim 3, and slidably adjustable in the axial direction of the associated branch openings, an advantageous symmetrical air velocity bias is obtained about the plate-shaped locking means when it is axially shifted with respect to the duct flow and thereby decreases air flow. .
15 Opfindelsen beskrives i det følgende nærmere under henvisning til tegningen, hvor fig. 1 viser et fordelings- eller samlingsrør ifølge opfindelsen i længdesnit, og fig. 2 viser et fordelings- eller samlingsrør ifølge fig. 1 i 20 tværsnit.The invention will now be described in more detail with reference to the accompanying drawings, in which: FIG. 1 is a longitudinal sectional view of a distribution or assembly pipe, and FIG. 2 shows a distribution or assembly pipe according to FIG. 1 in 20 cross sections.
