DK 153806 BDK 153806 B

Opfindelsen omhandler en fremgangsmåde og et organ til afbalancering af varmeafgivelse fra et varmeførende fluidums gennemstrømningsmasse i et centralvarmeanlægs radiatorer og af den i henholdsvis krav l's og krav 2's 5 indledning angivne art.BACKGROUND OF THE INVENTION The present invention relates to a method and means for balancing heat dissipation from the flow mass of a heat-carrying fluid in the radiators of a central heating system and of the nature specified in the preamble of claim 1 and claim 2, respectively.

I et centralvarmeanlæg doseres gennemstrømningsmassen af varmemediet, normalt varmt vand, ved at indstille forskellige ventiler således, at fluidets gennemstrømningsmasse fordeles korrekt igennem de enkelte radia-10 torer uanset disses større eller mindre afstand fra varmekilden, dvs. kedlen, for at kompensere for trykfaldene i anlæggets rørsystem. Denne operation kaldes "afbalancering af radiatorerne".In a central heating system, the flow mass of the heating medium, usually hot water, is dosed by adjusting different valves such that the fluid flow mass is distributed correctly through the individual radiators irrespective of their greater or less distance from the heat source, ie. the boiler, to compensate for the pressure drops in the system's piping system. This operation is called "balancing the radiators".

En sådan afbalancering kræver en nøjagtig forudbereg-15 ning af de enkelte radiatorhaneindst illinger samt en frembringelse af kunstige tryktab over i anlæggets rørsystem indskudte reguleringsspjæld, normalt i form af et T-stykke eller en bøjning med en stigeledningsventil med et forskydeligt ventillegeme til ændring af varme-20 mediets gennemstrømningsåbning til hver radiator. Her til leverer fabrikanterne nomogrammer til bestemmelse af tryktabene som følge af ventilnålestillingen.Such balancing requires an accurate pre-calculation of the individual radiator tap settings as well as the generation of artificial pressure losses inserted into the system's pipe system, usually in the form of a tee or bend with a ladder valve with a slidable valve body for changing heat. -20 medium throughput opening for each radiator. In addition, manufacturers supply nomograms to determine the pressure losses due to the valve needle position.

Sådanne reguleringer på basis af teoretiske beregninger samt de optrædende installationstilfældigheder kræver en 25 præcis regulering, idet en meget lille vinkeldrejning af ventilnålen medfører en væsentlig ændring af tjryktabet.Such adjustments on the basis of theoretical calculations as well as the occurrence of installation instances require precise regulation, since a very small angular rotation of the valve needle results in a substantial change in the pressure loss.

Fra beskrivelsen til norsk patent nr. 95 665 kendes en sådan stigeledningsventil til brug ved en afbalancering af radiatorer ved udøvelse af den i krav l's indled-30 ning angivne fremgangsmåde. I den kendte ventil måles tryktabet over en manuelt regulerbar gennemstrømningsåbning på hver sin side af åbningen inden for et 2From the disclosure of Norwegian Patent No. 95,665, such a ladder conduit valve is known for use in balancing radiators by carrying out the method set out in the preamble of claim 1. In the known valve, the pressure loss is measured over a manually adjustable flow opening on each side of the opening within a 2

og samme, ret voluminøse ventilhus, så at selve reguleringen virker tilbage på trykmålingen, så der må foretages flere successive indstillinger, før den ønskede gennemstrømningsmasse er opnået.and the same, rather bulky valve housing, so that the control itself acts back on the pressure measurement, so that several successive settings must be made before the desired flow mass is obtained.

5 Denne ulempe kan accepteres for en ventil til labora toriebrug, men er uacceptabel for afbalancering af radiatorer i et større centralvarmeanlæg, hvor montøren skal kunne indstille alle ventilerne med et rimeligt lille tidsforbrug.5 This disadvantage can be accepted for a valve for laboratory use, but is unacceptable for balancing radiators in a larger central heating system, where the installer must be able to adjust all the valves with a reasonably small time consumption.

10 Opfindelsen har til formål at tilvejebringe en frem gangsmåde af den angivne art til afbalancering af gennemstrømningsmassen i et centralvarmeanlægs radiatorer, uden at reguleringen virker tilbage på trykmålingen, hvorved der kun kræves en enkelt montøroperation til 15 opnåelse af den ønskede afbalancering for hver enkelt radiatorhane.The invention has for its object to provide a method of the specified type for balancing the flow mass in the radiators of a central heating system without controlling the pressure measurement, thus requiring only a single fitting operation to achieve the desired balancing for each individual radiator valve.

Dette opnås ifølge opfindelsen ved en fremgangsmåde af den i krav l's indledning angivne art, der er ejendommelig ved den i krav l's kendetegnende del angivne for- 20 anstaltning. Her kan installatøren indkoble sit different ialmanometer på anlæggets enkelte radiatorer efter tur og øjeblikkeligt konstatere konsekvensen af sin reguleringsaktion og nøjes med en enkelt indstillingsaktion for hver radiator.This is achieved according to the invention by a method of the kind set out in the preamble of claim 1, which is characterized by the method of claim 1. Here, the installer can switch on its different ialmanometer on the system's individual radiators in turn and immediately ascertain the consequence of its control action and settle for a single setting action for each radiator.

25 Et afbalanceringsorgan til udøvelse af fremgangsmåden ifølge opfindelsen kan som angivet i krav 2 udformes som en samlet enhed, der letter indmonteringen i rørsystemet og justeringsoperationen under afbalanceringen .A balancing means for carrying out the method according to the invention can, as stated in claim 2, be designed as a single unit which facilitates installation in the pipe system and the adjustment operation during the balancing.

3 af typen "Kent" med to diametralt modsat hinanden i et radialplan udad ragende aflukkelige afgreningsrør, til hvilke differentialmanometermåleslanger vanskeligt kan tilsluttes under knebne pladsforhold, som tilfældet of-5 te er i centralvarmeanlæg mellem radiatorernes retur ledning og gulvfladen. Til afhjælpning af denne ulempe kan afbalanceringsorganets måleventil udformes som angivet i krav 3.3 of the "Kent" type with two diametrically opposite each other in a radially plane outwardly projecting closable branch tubes to which differential gauge measuring hoses can be difficult to connect under tight space conditions, as is often the case in central heating systems between the return line of the radiators and the floor surface. To remedy this disadvantage, the balancing means of the balancing means can be designed as claimed in claim 3.

Afbalanceringsorganet ifølge opfindelsen er let at frem-10 stille i seriefabrikation, har et beskedent pladsbehov og frembyder en let manometertilslutning in situ.The balancing means according to the invention is easy to manufacture in series fabrication, has a modest space requirement and provides a light gauge connection in situ.

Opfindelsen forklares nærmere nedenfor i forbindelse med tegningen, hvor: fig. 1 er en skematisk afbildning af et centralvar-13 meanlæg med radiatorer til udøvelse af opfindelsen, fig. 2 er et længdesnit igennem et tilslutningsstykke ifølge opfindelsen, fig. 3 og 4 er afbildninger fra enden af ventillegemerne i tilslutningsstykket på fig. 2, og • 20 fig. 5 er et snit igennem et greb til at åbne og lukke hvert af ventillegemerne i tilslutningsstykket på fig. 2.The invention is further explained below in connection with the drawing, in which: FIG. Fig. 1 is a schematic view of a central heating system with radiators for carrying out the invention; 2 is a longitudinal section through a connector according to the invention; FIG. 3 and 4 are views from the end of the valve bodies in the connector of FIG. 2, and FIG. 5 is a section through a handle for opening and closing each of the valve bodies in the connector of FIG. 2nd

Som forklaret ovenfor er det nødvendigt at regulere gennemstrømningsmassen af det varmebærende fluidum ud for de enkelte radiatorer således, at disse kan udsende 5 den ønskede varmemængde.As explained above, it is necessary to regulate the flow mass of the heat-carrying fluid next to the individual radiators so that they can emit the desired amount of heat.

Til dette formål bestemmer man ifølge opfindelsen gennemstrømningsmassen af fluidet ved udløbet fra hver radiator 2 efter tur, og dersom den bestemte mængde ikke svarer til den forud beregnede værdi, ændrer man 10 gennemstrømningen af det varmeførende fluidum ved at ændre den ved en konventionel reguleringsbøjning 5 indførte indsnævring.For this purpose, according to the invention, the flow mass of the fluid at the outlet of each radiator 2 is determined in turn, and if the determined amount does not correspond to the predetermined value, the flow of the heat-carrying fluid is changed by changing the flow introduced by a conventional control bend 5. narrowing.

Til iværksættelse af disse målinger anbringes i rørsystemet 4 (eller 3) i umiddelbar nærhed af regulerings-15 bøjningen 5 et tilslutningsstykke 6 af den på fig. 2 viste art. Tilslutningsstykket 6 omfatter en cylinderformet muffe 7, hvis ene ende er indskruet i udløbet fra bøjningen 5, mens dets modsatte ende er tilsluttet på passende måde til rørsystemet 4. Boringen i muffen 7 20 omfatter en tværgående skillevæg 8 med en central dyse 9.To take these measurements, in the pipe system 4 (or 3), in the immediate vicinity of the control bend 5, a connection piece 6 of the one shown in FIG. 2 art. The connector 6 comprises a cylindrical sleeve 7, one end of which is screwed into the outlet of the bend 5, while its opposite end is suitably connected to the pipe system 4. The bore of the sleeve 7 20 comprises a transverse partition 8 with a central nozzle 9.

Endvidere omfatter tilsslutningsstykket 6 to studse 10, hvis geometriske akse hælder imod eller står vinkelret på muffen 7. Hver af studsene 10 er udformede som en hul bøsning 11 med et indvendigt gevind 11a. Det indre 25 parti af bøsningen 11 står i forbindelse med den cen trale boring i muffen 7 over en lille åbning 11b, som kan danne et lejesæde for en ventilnål 12, der kan skrues langs gevindet 11a i bøsningen 11. Ventilnålen 12 har en spalte 12a til aktivering af nålen samt en 30 plan flade 12b (fig. 3), så at der, når ventilnålen 12 ligger i afstand fra sædet 11b, er forbindelse imellem den centrale boring i muffen 7 og det indre af bøsningen 11. Denne omfatter endvidere et udvendigt gevind 5Furthermore, the connecting piece 6 comprises two studs 10, the geometric axis of which is inclined towards or perpendicular to the sleeve 7. Each of the studs 10 is formed as a hollow bush 11 with an internal thread 11a. The inner portion of the sleeve 11 communicates with the central bore of the sleeve 7 over a small opening 11b which can form a bearing seat for a valve needle 12 which can be screwed along the thread 11a of the sleeve 11. The valve needle 12 has a slot 12a for activating the needle and a flat surface 12b (Fig. 3) so that when the valve needle 12 is spaced from the seat 11b, there is a connection between the central bore of the sleeve 7 and the interior of the sleeve 11. This further comprises a external thread 5

lie, på hvilket der er indskruet en hætte 13.Ion, on which is fitted a cap 13.

Det bemærkes, at mundingerne af de små åbninger 11b i den centrale boring i muffen 7 befinder sig på hver sin side af den tværgående skillevæg 8.It is noted that the mouths of the small openings 11b in the central bore of the sleeve 7 are located on either side of the transverse partition 8.

3 Hver af ventilnålene 12 kan omfatte en langsgående not 12c (fig. 4) i stedet for den plane flade 12b, men som har den samme funktion.Each of the valve needles 12 may comprise a longitudinal groove 12c (Fig. 4) in place of the planar surface 12b, but having the same function.

Fig. 5 viser, hvorledes hvert af tilslutningsstykkerne 6 manøvreres således, at de to sonder 14a og 14b af et 10 differentialmanometer 14 kan måle trykket af den var- meførende væske på hver side af tilslutningsstykkets tværgående skillevæg 8.FIG. 5 shows how each of the connecting pieces 6 is operated so that the two probes 14a and 14b of a differential pressure gauge 14 can measure the pressure of the heating fluid on each side of the transverse partition 8 of the connecting piece.

Enden af sonden 14a, der er den samme som enden af sonden 14b, er forsynet med et mundstykke 15, der er udfor-15 met som en ring 16 med en radial nippel 17, i hvilken den be tragtede ende af sonden er indsat tætsluttende. I den centrale boring i ringen 16 er der indsat et legeme 18 af en hane, i hvilken der strækker sig en spindel 19 forbundet med et manøvregreb 20. Ved hjælp af en møtrik 20 21 på den frie ende af legemet 18 kan mundstykket 15 holdes på plads i anlæg mod hovedet 18a af legemet 18.The end of the probe 14a, which is the same as the end of the probe 14b, is provided with a nozzle 15 which is formed as a ring 16 with a radial nipple 17 into which the distal end of the probe is sealed tightly. In the central bore of the ring 16 there is inserted a body 18 of a cock, in which extends a spindle 19 connected to a maneuvering grip 20. By means of a nut 20 21 on the free end of the body 18, the nozzle 15 can be held on space in abutment against the head 18a of the body 18.

Dette omfatter en central aftrappet boring 18b, 18c, igennem hvilken spindelen 19 strækker sig tætsluttende takket være pakninger 22. Legemet 18 omfatter en peri-25 ferisk rille 18d, i hvilken det centrale hul 17a i nip- pelen 17 udmunder, og som står i forbindelse med partiet 18b af boringen i legemet 18 gennem en åbning 18e. Tætslutningen ud for ringen 16 tilvejebringes ved hjælp af to pakringe 23, som er anbragt i legemet 18 på hver 30 sin side af rillen 18d.This includes a central stepped bore 18b, 18c through which the spindle 19 extends tightly, thanks to gaskets 22. The body 18 comprises a peripheral groove 18d, into which the central hole 17a of the nipple 17 opens, and connecting to the portion 18b of the bore in the body 18 through an opening 18e. The seal closure off the ring 16 is provided by two packing rings 23 which are disposed in the body 18 on each side of the groove 18d.

Efter at hver radiator er forsynet med et tilslutningsstykke 6, udøves fremgangsmåden ifølge opfindelsen ved 6After each radiator is provided with a connector 6, the method of the invention is practiced at 6

som angivet nedenfor at måle gennemstrømningsmassen af det varmeførende fluidum ud for det enkelte tilslutningsstykke. Allerførst afskrues de to hætter 13, som tætsluttende dækker den frie ende af hver bøsning 11, 5 og derefter skrues den modsat møtrikken 21 beliggende gevindskårende ende 18f af legemet 18a på gevindet 11c på hver bøsning 11 (fig. 5). Tætslutningen tilvejebringes her ved hjælp af en pakning 24, der forbliver permanent ved bunden af gevindet 18f.as indicated below, to measure the flow mass of the heat-carrying fluid next to the individual connector. First, the two caps 13, which tightly cover the free end of each bush 11, 5, are unscrewed and then the threaded end 18f of the body 18a of the thread 18a is screwed onto the thread 11c of each bush 11 (Fig. 5). The seal closure is provided here by means of a gasket 24 which remains permanently at the bottom of the thread 18f.

10 På dette tidspunkt kan spindelen 19 forskydes aksialt således, at dens fortyndede ende 19a kommer til indgreb i spalten 12a i ventilnålen 12 således, at man ved drejning af grebet 20 i den rigtige omløbsretning fremkalder en udskruning af ventilnålen. Det varmebæ-15 rende fluidum vil da strømme igennem den lille åbning 11b og derefter langs med ventilnålen 12 som følge af tilstedeværelsen af dennes plane flade 12b eller not 12c og nå frem til mellemrummet imellem partiet 18b af boringen i legemet 18 og spindelen 19, hvorfra fluidet 20 strømmer ind i sonden 14a igennem først åbningen 18e og derefter hullet 17a. Det samme er tilfældet for den anden bøsning 11, så at man altså på differentialmano-meteret 14 kan aflæse gennemstrømningsmassen af fluidet igennem tilslutningsstykket 6. Hvis den aflæste værdi 25 ikke svarer til den beregnede værdi, ændres indsnævringen i bøjningen 5 til opnåelse af den ønskede værdi på manometerets gradskive.At this point, the spindle 19 can be displaced axially so that its diluted end 19a engages in the slot 12a of the valve needle 12, so that by turning the handle 20 in the right direction of rotation, a screwing out of the valve needle is induced. The heat-carrying fluid will then flow through the small opening 11b and then along the valve needle 12 due to the presence of its flat surface 12b or groove 12c and reach the space between the portion 18b of the bore in the body 18 and the spindle 19, from which the fluid 20 flows into the probe 14a through first the opening 18e and then the hole 17a. The same is true of the second sleeve 11, so that one can read on the differential pressure gauge 14 the fluid mass through the connection piece 6. If the read value 25 does not correspond to the calculated value, the constriction in the bend 5 is changed to obtain the desired value on the manometer's protractor.

Fremgangsmåden gentages fra radiator til radiator, indtil hele anlægget er fuldstændigt afbalanceret.The process is repeated from radiator to radiator until the entire system is completely balanced.

30 Det forstås, at den tværgående skillevæg 8 i muffen 7 af tilslutningsstykket 6 kan være demonterbar, så at man kan ændre tværsnitsarealet af dysen 9. Man kan også direkte gradere manometerets gradskive i varmeenhe-It is understood that the transverse partition 8 in the sleeve 7 of the connection piece 6 can be removable, so that the cross-sectional area of the nozzle 9. can be changed.

7 der. Tilslutningsstykket 6 kan også alternativt indskydes i tilgangsrørsystemet 3 eller integreres med bøjningen 5 eller med den betragtede radiatorhane.7 there. Alternatively, the connecting piece 6 can be inserted into the inlet pipe system 3 or integrated with the bend 5 or with the considered radiator tap.
