Kunststoffi solerlegeme for etterisolering au rør Plastic solar body for post-insulation au pipes
Oppfinnelsen angår et kunststoffi solerlegeme for etteri sol ering au' de auisolerte f orbindelsessteder , avgreningssteder og bend au fabriksmessig forhåndsisol erte, metalliske ledningsrør, bestående au to identiske haluskall huis delingsplan forløper i ledningsrørets akseretning, og som ued hjelp au tapper og tilsuarende boringer er løsbart forbundet med hverandre idet de omgir det auisolerte rørstykke. The invention relates to a plastic solar body for post-solation and the uninsulated connection points, branching points and bends in factory-pre-insulated metallic conduits, consisting of two identical hollow-shell housings, the division plane of which runs in the axial direction of the conduit, and which is removable without the help of studs and connecting bores connected to each other as they surround the insulated piece of pipe.
l/ed husinstallasjon, særlig for varmtvannsforsyningl/ed house installation, especially for hot water supply
og for oppuarming, blir det i tiltagende grad benyttet kopper-rø'r som er f orhåndsi sol ert på fabrikk. Disse på markedet til-gjengelige rør utmerker seg ued en særlig enkel legging og ued meget gode uarmeisolasjonsegenskaper. For fremstilling au forbindelses-, forgrenings- eller krumningssteder blir først den på fabrikken påførte i sol asjonsmantel fjernet, de to rør-ender sammenloddes med den tilsuarende rørfitting, og deretter etterisoleres det auisolerte sted. and for heating, copper pipes are increasingly being used which are pre-insulated at the factory. These pipes available on the market are distinguished by their particularly easy laying and very good arm insulation properties. For the production of connection, branching or bending points, the factory-applied insulation jacket is first removed, the two pipe ends are soldered together with the fitting pipe fitting, and then the uninsulated place is post-insulated.
Etterisoleringen au slike forbindélsessteder ble tidligere gjennomført ued omuikling med passende materialer eller ued pålegning au kunststoffhaluskåler som ble sammenlimt med huerandre eller omgitt au en bandasje.Da fremstillingen au omviklinger uar meget tidkreuende og. au plassgrunner ofte uar meget omstendelig, betydde innføringen au haluskåler en be-tydelig teknisk uidereutuikling. Imidlertid kunne haluskålene fremdeles ikke uære helt tilfredsstillende, da de uar forholds-uis dyre og spesielle haluskåler måtte holdes på lager for huer rørdimensjon. The post-insulation at such connection points was previously carried out without re-wrapping with suitable materials or without the application of plastic hollow cups which were glued together with other hair or surrounded by a bandage. au reasons of space often uar very laborious, the introduction of au halu bowls meant a significant technical redevelopment. However, the hollow bowls were still not completely satisfactory, as the disproportionately expensive and special hollow bowls had to be kept in stock for larger pipe dimensions.
Formålet med oppfinnelsen er således å ti 1ueiebringe et kunststoffisolerlegeme som kan fremstilles økonomisk som sprøytestøpningsartikkel med korte sp røytestøpningstider og likevel er formstabilt, som kan monteres enkelt og-lettvint med enkle midler,som er like anuendelig for flere rørdimensjoner, for vinkler og krumninger, som har heltettende delingsflater og kanter og som oppviser gode uarmei sol a-s j on s uerdi er og etter-later et godt optisk inntrykk. The purpose of the invention is thus to provide a plastic insulator body which can be produced economically as an injection-moulded article with short injection-moulding times and yet is dimensionally stable, which can be assembled simply and easily with simple means, which is equally suitable for several pipe dimensions, for angles and curvatures, as has completely sealing dividing surfaces and edges and which exhibits good unarmei solar a-sjon s uerdi er and leaves a good optical impression.
Ued et kunststoffi solerlegeme au den inniedningsuis angitte type oppnås ouenneunte formål ued at boringene oppuiser både en aufasing og en underskjæring, at tappene har en tilsuarende avskråning og en til denne tilsluttende dia meterreduksjon, og at tappene er slik utformet at de etter sammenføyning av halvskålene fjærer tilbake i boringenes underskjæringer. With a synthetic solar body of the type specified below, unusual objectives are achieved in that the bores fill up both a chamfer and an undercut, that the studs have a matching chamfer and a connecting diameter reduction, and that the studs are designed in such a way that after joining the half-shells they spring back into the undercuts of the boreholes.
Kun ststo ffi solerlegemet ifølge oppfinnelsen lar seg lett fremstille ved sp røytestøpning og er lett. å montere og demontere. The plastic solar body according to the invention can be easily produced by injection molding and is light. to assemble and disassemble.
Ytterligere fordelaktige utførelser av oppfinnelsen er angitt i underkra vene. Further advantageous embodiments of the invention are specified in the subclaims.
Oppfinnelsen skal beskrives nærmere i det følgendeThe invention shall be described in more detail below
i forbindelse med.et utførelseseksempel som er skjematisk vist på tegningene, der. fig. 1 viser en i solerhalvskål for 90°-bend og 90°-vinkler, fig. 2 viser et snitt etter linjen A - A på fig. 1 og fig. 3-5 viser forstørrede detaljtegninger. in connection with.an embodiment which is schematically shown in the drawings, where. fig. 1 shows one in a sun half bowl for 90° bends and 90° angles, fig. 2 shows a section along the line A - A in fig. 1 and fig. 3-5 show enlarged detail drawings.
På fig. 1 er vist en i solerhalvskål 1 for 90°-bend In fig. 1 shows one in sun half bowl 1 for 90° bend
og for 90°-vinkler som forbundet med en ytterligere, likeartet halvskål frembringer kunststoffi solerlegemet for etterisolering av et 90°-bend eller en 90°-fitting på fabrikk.smessig forhåndsisolerte ledningsrør. Isolerlegemets midtre område eller mellomområde 2 omslutter det i sol a s jon.sf ri e eller blanke rør-bend eller den blank-e rørforbindelsesdel (fitting) og er med hensyn til konturer o.g dimensjoner formet slik at flere forskjellig store bend eller rørforbindelsesdeler valgfritt kan innlegges på passende måte i det samme mellomområde 2. Mellornornrådet 2 utgjør samtidig et slags luftkammer som skal' forbedre kunststoffi solerlegemets i solasjonsvirkning ytterligere. Luftkammeret 4 slutter seg på sluseliknende måte til mellomområdet 2. På liknende måte som ved i solerglassruter drar man her nytte av at den innesluttede, ubevegelige luft i luftkamrene 2 og 4 er en god og billig uarmeisolator. Luftkamrene 4 omslutter sirkelformet metallrørets isolasjon. Med luftkamrene 4 er forbundet avtrappede ansatser 3. Disse er med hensyn til sin innerdiameter slik avstemt at denne svarer til ytterdiameteren av forskjellig kunststoffommantlede led-nin.gsrør. • Den siste forhåndenværende og minste avtrapning omslutter alltid metallrørets isolasjon. På ansatsenes 3 innervegg er dannet tetningslepper 18. som skal forbedre av-stengningen av den i det indre rom 2 innesluttede luft. l/ed hjelp av forskjellige krumningsradier på ytterkonturene i halvskålens krumningsområde 12 muliggjøres anvendelighet av and for 90° angles which are connected with a further, similar half-bowl, the plastic solar body produces the post-insulation of a 90° bend or a 90° fitting on factory pre-insulated conduits. The insulator body's middle area or intermediate area 2 encloses it in sun-free or blank pipe bends or the blank pipe connection part (fitting) and is shaped in terms of contours and dimensions so that several differently sized bends or pipe connection parts can optionally be inserted in a suitable manner in the same intermediate area 2. The Mellornornrådet 2 also constitutes a kind of air chamber which will further improve the solation effect of the synthetic solar body. The air chamber 4 joins in a sluice-like manner to the intermediate area 2. In a similar way as in solar glass panes, one benefits here from the fact that the enclosed, motionless air in the air chambers 2 and 4 is a good and cheap arm insulator. The air chambers 4 enclose the circular metal pipe insulation. Connected to the air chambers 4 are stepped projections 3. With regard to their inner diameter, these are matched in such a way that this corresponds to the outer diameter of various plastic-sheathed conduit pipes. • The last available and smallest taper always encloses the metal pipe's insulation. Sealing lips 18 are formed on the inner wall of the projections 3, which are to improve the shut-off of the air enclosed in the inner space 2. l/ed with the help of different radii of curvature on the outer contours in the curvature area 12 of the half-bowl, the applicability of
etterisoleringslegemet for forskjellige på markedet eksisterende 90°-bend og for forskjellige på markedet eksisterende 90°-vinkler. Halv/skålen 1 kan i mellomområdet 2 på ikke vist måte også the additional insulation body for various 90° bends available on the market and for various 90° angles available on the market. The half/bowl 1 can also be in the middle area 2 in a manner not shown
være ovalt formet, idet den lange akse forløper i delings-planets retning. I i sol erhal v skå 1 en s 1 randområder er det anbragt et antall tapper 8 og tilsuarende boringer 9 ued hjelp au huilke haluskålene 1 kan forbindes med hverandre til et etterisoleringslegeme. Notene 5 og tilsuarende fjærer 6 be oval shaped, with the long axis running in the direction of the division plane. A number of studs 8 and connecting bores 9 are placed in the edge areas of the sol erhal v skå 1 and s 1, with the help of which the hollow bowls 1 can be connected to each other to form a post-insulation body. The notes 5 and accompanying springs 6
tjener til autetning og bedre føring au de enkelte haluskåler 1. serves for sealing and better guidance in the individual hollow bowls 1.
Slik som uist på fig. 2, kan haluskålens 1 tverrsnitt uære utført med forskjellig ueggtykkelse. l/eggtykkelsen tiltar her stadig mot området for delingsplanet. Dette har •den fordel at det på den ene side er for hånden plass for tappene 8 og boringene 9 i den sprøytede uegg au- i solerlegemets mellomområde, og at den sprøytede uegg på den annen side kan uære forholdsvis tynn for oppnåelse au korte aukjølingstidér ued sprøytestøpningen. Videre oppnås det derued korte sprøyte-støpningstider og sp røytestøpningsmaterialbesparelse med derav resulterende, mer økonomisk og prisgunstig fremstilling. As illustrated in fig. 2, the cross-section of the head bowl 1 can be made with different egg thickness. The l/egg thickness here steadily increases towards the area of the dividing plane. This has the advantage that on the one hand there is room for the pins 8 and the bores 9 in the sprayed egg in the middle area of the solar body, and that the sprayed egg can on the other hand be relatively thin to achieve short cooling times the injection molding. Furthermore, short injection molding times and injection molding material savings are achieved, resulting in more economical and cost-effective production.
Haluskålene 1 oppuiser tapper 8 som etter sammen-føyningen au begge haluskåler grip.er inn i xasterspor i tilsuarende boringer 9 i den motstående haluskål 1. For dette formål er tappene 9 enten utformet hule eller, slik som uist på fig. 5, forsynt med en spalte eller sliss 8a. De fjærende, ' slissede tapper 8 muliggjør på den ene side på tross au større tappantall en lettgående montering for hånd og uten ekstra hjelpeuerktøy, og på den annen side sikres ikke desto mindre den i funksjon nøduendige tilholdingskraft også under hensyn-tagen til den under bruk opptredende uarmeinnuirkning (80-9D°C). Boringene 9 (se fig. 4) er utformet i overensstemmelse med tappene 8 og oppviser en avfasing-9a som skal utjevne små forskjeller som kan forekomme i sp røytestøpningsdeler, eksem-pelvis på grunn av krympning, skjevhet, material spenninger osv. Avskråningen 8b på tappene,8 tjener det samme formål.. The hollow bowls 1 hold studs 8 which, after the jointing of both hollow bowls, are gripped into xaster grooves in adjacent bores 9 in the opposite hollow bowl 1. For this purpose, the pegs 9 are either designed hollow or, as shown in fig. 5, provided with a slot or slot 8a. The sprung, 'slotted pins 8 on the one hand, despite the larger number of pins, enable an easy assembly by hand and without additional auxiliary tools, and on the other hand, the holding force unnecessary in function is nevertheless ensured, also taking into account the during use appearing unarmed (80-9D°C). The bores 9 (see fig. 4) are designed in accordance with the pins 8 and exhibit a chamfer 9a which is to equalize small differences that may occur in injection molded parts, for example due to shrinkage, distortion, material stresses etc. The bevel 8b on the pins,8 serve the same purpose..
De avtrappede ansatser 3 er utstyrt med avsnittsriller 10. l/ed hjelp av disse avsnittsriller 10 muliggjøres at det meget enkelt - ved hjelp av lommekniv - alt etter behov kan avskjæres på den tilsvarende rørdimensjon. Avsnittsri11 en 10 reduserer den vegg som skal gjennomskjæres og danner en føring for sk jærekrii v/en. Ued hjelp av/ av/skjæringen v/ed av-snittsrillen 10 sikres at det også ved beskårne kunststoff-isolerlegemer er til stede en tilstrekkelig overlapping av kunststoffisolerlegemevegg og røri solasjonsvegg. Avsnitts-rillen 10. har V-formet tverrsnitt og er slik anordnet at i solerlegemets 1 snittkant etter beskjæringen ikke er skarp-kan tet, men avfaset. The stepped projections 3 are equipped with section grooves 10. With the help of these section grooves 10, it is possible that everything can be cut to the corresponding pipe dimension very easily - with the help of a pocket knife - as needed. Section lines 11 and 10 reduce the wall to be cut through and form a guide for cutting the cutting edge. With the help of/off/cutting with the cut-off groove 10, it is ensured that there is sufficient overlapping of the plastic insulation body wall and pipe insulation wall, even with cut plastic insulation bodies. The section groove 10. has a V-shaped cross-section and is arranged in such a way that the section edge of the solar body 1 after trimming is not sharp-edged, but chamfered.
På en eller flere av de avtrappede ansatser 3 er det utvendig påsprøytet tangentialt på ansatsdiameteren ut-løpende forhøyninger på hvilke det befinner.seg ekstra tapper 8 og boringer 9. På denne måte sikres at også kunststoff-isolerlegemer som på grunn av sprøytestøpningsmetoden er lett forvridd eller beheftet med eventuelle,materi al spenninger, On one or more of the stepped projections 3, elevations extending tangentially to the projection diameter have been sprayed on the outside, on which there are additional pins 8 and bores 9. In this way, it is ensured that even plastic insulating bodies which are easily distorted due to the injection molding method or burdened with any material tensions,
på tross av varmeinnvirkninger i funksjonsområdet ved mon-teringen slutter tett og under bruk på tross av aldrings-effekter forblir tette over.lengre tidsrom og således holder varmelekkasjetap så små som mulig. despite heat effects in the functional area during assembly, it ends up tight and during use, despite aging effects, remains tight over a longer period of time and thus keeps heat leakage losses as small as possible.
I overgangsområdet til ansatsene 3 kan det være dannet planformribber eller riller 16 slik som vist på fig. 3, for å motvirke den naturlige krympeoppførsel ved støpestykkenes uttagning med henblikk på oppnåelse av planflate isoler-legemehalvskåler ved forholdsvis kort sprøytestøpningstid. Fordelen er-at det på tross av økonomiske, korte, sprøyte-støpningstider oppnås planflate sprøytestykker som oppfyller kvalitetskravene med hensyn til god monterbarhet og små varmeisolasjonstap på grunn av for stor spalte. In the transition area of the projections 3, planar ribs or grooves 16 may be formed as shown in fig. 3, in order to counteract the natural shrinking behavior when the castings are taken out with a view to obtaining flat insulator half-shells with a relatively short injection molding time. The advantage is that, despite economical, short injection molding times, flat injection moldings are obtained that meet the quality requirements with regard to good fitability and small heat insulation losses due to too large a gap.
