Prirobnični profil za medsebojno pritrjevanje delnih kosov zračnega kanalaFlange profile for interconnection of partial pieces of air duct
Izum zadeva prirobnični profil za prirobnično zvezo za medsebojno pritrjevanje v preseku v bistvu pravokotnih delnih kosov zračnega kanala iz pločevine, predvsem za visokotlačne napeljave za vodenje zraka.The invention relates to a flange profile for a flange connection for interconnection in cross-section of substantially rectangular partial pieces of a sheeted air duct, in particular for high-pressure air ducts.
Znano je, da se kanalski delni kosi uvodoma opredeljene vrste sestavljajo s kot okviri narejenimi kotnimi profili.It is known that the canal partial cuts of a predefined species are composed of angular profiles as frames.
Patentni spis DE 27 58 295 razkriva prirobnični profil, ki - sestavljen z delnim kosom zračnega kanala po načinu z okvirom - omogoča povezavo kosov zračnega kanala. Pri tem je pločevina profila zračnega kanala vstavljena med v bistvu vzporedna kraka prirobnice. Da se izognejo uhajanju zraka, je v kraka prirobnice, ki ležita drug nasproti drugemu in sta usmerjena pravokotno na pločevino zračnega kanala, vloženo elastično tesnilo. Pomanjkljivo pri tem je, da je tesnilna masa zelo voluminozna.DE 27 58 295 discloses a flange profile which, consisting of a partial piece of an air duct according to frame mode, enables connection of pieces of an air duct. The air duct profile sheet is inserted between substantially parallel flange arms. In order to avoid air leakage, an elastic seal is inserted into the flanges of the flange opposite each other and directed perpendicularly to the sheet of the air duct. The disadvantage is that the sealing compound is very voluminous.
V nadaljnjem ono zaradi svoje delne uvrstitve, ki jo drži neki mostič, ne zagotavlja čez in čez popolne zatesnitve delov zračnega kanala.In the future, because of its partial alignment, held by a bridge, it does not provide over and over complete sealing of air duct parts.
Patentni spis DE 35 12 669 razkriva izvedbo profilov zračnega kanala, pri kateri so na pločevine dela zračnega kanala, v obliki, ki je v sebi zaprta, prioblikovane prirobnice, ki so zasnovane za povezavo delov zračnega kanala.DE 35 12 669 discloses an embodiment of air duct profiles in which flanges are formed on the sheets of the air duct, in a sealed manner, designed to connect parts of the air duct.
Pločevine zračnega kanala se pri tem upognejo v obliki prirobnice in tvorijo prostorsko sklenjen konstrukcijski del. Končni del oblikovane prirobnice je v zgibu, razporejenem na mestu prehoda, oblikosklepno prilagojen pločevini zračnega kanala.The air duct sheets bend in the form of a flange and form a spatially contracted structural part. The end portion of the molded flange is adapted to the air duct sheet in a joint arranged at the passageway.
Ta izvedba sicer privede do v bistvu popolne odprave izstopanja zraka iz profilov zračnega kanala, jo je pa s tehnološkega vidika skrajno težko izdelati in pogojuje veliko izdelovalnega vložka. Za zračne kanale velikega formata je tovrstna izvedba možna le z velikimi gospodarskimi vlaganji.Although this embodiment results in essentially eliminating air leakage from the air duct profiles, it is extremely difficult to manufacture from a technological point of view and causes a lot of manufacturing input. For large format air channels, this kind of implementation is only possible with large economic investments.
V patentu SU 1.574.184 A3 je razkrit prirobnični profil uvodoma opredeljene vrste, ki ima med dvojicami krakov, potekajočimi vzporedno s pločevino zračnega kanala, žmulo, v katero je vložena tesnilna masa. Tesnilna masa ima ustnico, kije usmerjena proti pričakovanemu zračnemu toku, in zatesnjuje vstavljeno pločevino profila zračnega kanala proti preostalemu delu prirobnice za povezavo zračnega kanala. Izvedbe po rešitvi iz patenta pa zaradi svojih tehničnih izvedb niso funkcijsko zanesljive, ker se pri vstavljanju pločevine zračnega kanala med kraka profila tesnilna plast premakne iz žmule pa v prirobnico.SU 1.574.184 A3 discloses a flange profile of a pre-defined type having between the twin arms extending parallel to the air duct sheet a groove into which a sealing compound is inserted. The sealing mass has a lip that is directed toward the expected air flow and seals the inserted air duct profile sheet against the rest of the air duct connection flange. However, due to their technical designs, the designs according to the patent solution are not functionally reliable, since when inserting the air duct sheet between the legs of the profile, the sealing layer moves from the groove to the flange.
K pomanjkljivosti nezadovoljive funkcijske zanesljivosti pri montaži se pri tem pridruži še nenatančno naleganje prirobničnega profila na element zračnega kanala. Žmula, ki štrli v zračni kanal, ima v nadaljnjem pomembne funkcijske pomanjkljivosti, pri čemer v območju žmule nastopajo znatni zračni vrtinci, ki nato nadalje pri svojem vzvratnem teku vodijo k nabiranju umazanije in k poslabšanju celotne funkcije zračnega kanala.The disadvantage of insufficient functional reliability during mounting is the inaccurate alignment of the flange profile on the air duct element. The bulb protruding into the air duct continues to have significant functional defects, with significant air vortices present in the buccal area, which in turn reverses the accumulation of dirt and impairs the overall function of the air duct.
Patentni spis US 5,054,823 razkriva ureditev prirobnice zračnega kanala na elementu zračnega kanala. Prirobnični profil je nataknjen na element zračnega kanala, stični rob pločevine zračnega kanala zadene ob notranji vodilni rob prirobnice. Na kraku prirobničnega profila, ki se navpično vzpenja, je z usmeritvijo navznoter prioblikovana žmula. Delovna ploskev žmule je zasnovana z določeno špranjo nad pločevino zračnega kanala.No. 5,054,823 discloses an arrangement of an air duct flange on an air duct element. The flange profile is attached to the air duct element and the contact edge of the air duct sheet hits the inner leading edge of the flange. A bead is formed on the arm of the flange profile, which rises vertically, with the inward orientation. The working surface of the buzzer is designed with a slit above the air duct sheet.
Za odpravo izstopanja zraka iz prirobničnega elementa je ta špranja v območju med žmulo in pločevino zračnega kanala izravnana s tesnilom.To eliminate air leakage from the flange element, this gap is offset by a gasket in the area between the groove and the air duct sheet.
Ureditev v obliki, kakršna je znana iz omenjenega US-patenta, ima pomanjkljivost, da je naknadna uvrstitev tesnilnega elementa med profilno pločevino kanala in delovno ploskev žmule zelo zamotana. V primeru, da je tesnilni element uvrščen že pred namestitvijo na pločevino zračnega kanala, je nujno, da se pri vstavljanju pločevine zračnega kanala v območje med spodnjim krakom in tesnilnim elementom v prirobnici zračnega kanala dela poudarjeno z občutkom, ker se sicer tesnilni element premakne in postane neučinkovit.The arrangement in the form known from the aforementioned US patent has the disadvantage that the subsequent classification of the sealing element between the channel profile sheet and the working surface of the bucket is very complicated. If the sealing element is positioned prior to mounting on the air duct sheet, it is essential that the insertion of the duct sheet into the area between the lower arm and the sealing element in the air duct flange emphasizes the feeling, because otherwise the sealing element will move and becomes ineffective.
No, patentni spis DE 23 13 425 kaže ureditev žmule nad vodoravnim krakom profila zračnega kanala, na katerem vstavijo vzporedno potekajočo pločevino dela zračnega kanala. Žmula štrli v notranji prostor prirobnice in tvori ožeč se prejemni element za pločevino zračnega kanala.Well, the patent file DE 23 13 425 shows the arrangement of the bead above the horizontal leg of the air duct profile, on which a parallel running sheet of part of the air duct is inserted. The bead protrudes into the inner space of the flange to form a narrowing receiving element for the air duct sheet.
Najmanjši odmik ožečega se prejemnega segmenta je malo manjši ali enak debelini pločevine zračnega kanala. Pri vstavljanju pride pločevina med notranjo ploskev kraka in žmulni del in s tem zatesni spodnji del prirobnice, ne da bi bilo zajamčeno, da prirobnica funkcijsko pravilno poravnano sedi na kanalski pločevini in da se ne more ločiti, ker se pri dinamični obremenitvi, ki jo vsekakor lahko povzroči toplota, točkovna obremenitev, do katere pride na dotikalnem robu, zmanjša in prirobnica na kanalski pločevini ne prejme nikakršnega zanesljivega nalega.The minimum offset of the narrowing receiving segment is slightly less than or equal to the thickness of the air duct sheet. During insertion, the sheet comes between the inner surface of the limb and the bulbous part, thereby sealing the lower part of the flange, without guaranteeing that the flange is properly aligned on the channel sheet and cannot be separated, because in the dynamic load, which certainly can be caused by heat, the point load that occurs on the contact edge is reduced and the flange on the duct plate receives no reliable support.
Konstrukcija po rešitvi iz omenjenega DE-patenta ne jamči zanesljive, funkcijsko pravilne montaže, saj izdelovalne nenatančnosti, ki jih ne gre izključevati, slabo vplivajo na kontinuiteto v ohranjanju natančnosti položaja žmule proti kraku prirobnice. Spis DE 33 13 235 Al razkriva prirobniČno zvezo za pravokotne klimatizacijske kanale, ki imajo štiri stene, pri katerih so na čelno stran kosa zračnega kanala po načinu okvira nameščeni štirje prirobnični profili skupaj s štirimi pravokotnimi kotniškimi kosi (kotniki). Prirobnični profili so v bistvu kot kotniki oblikovani votlinski profili, ki so vsakokrat nataknjeni na steno kanala in tam fiksirani z več zvarnimi točkami.The construction after the solution of the aforementioned DE patent does not guarantee a reliable, functionally correct installation, since the manufacturing inaccuracies, which cannot be ruled out, adversely affect the continuity in maintaining the accuracy of the position of the flanges against the flange arm. File DE 33 13 235 Al discloses a flange connection for rectangular air conditioning ducts having four walls, with four flange profiles together with four rectangular angles (angles) mounted on the front of the air duct in the frame manner. Flange profiles are essentially angular shaped cavity profiles, which are each fixed to the wall of the channel and fixed there with several weld points.
Problematična se pri tem pojavlja zatesnitev med kraki prirobničnih profilov in steno kanala, ker zaradi medsebojnih razmikov, na katerih so razporejene zvarne točke, med notranjimi kraki prirobničnega profila in steno kanala na čelni strani stene kanala lahko zrak teče na prosto. Da se doseže boljša zatesnitev, je po omenjenem DE-spisu v votlinski profil - izhajajoč iz čelnega radialnega kraka profila zračnega kanala - s prednapetjem, usmerjenim k vodoravnemu kraku prirobnice, prioblikovana nekakšna žmula. Znotraj ležeč lok žmule s prižemnim ujemom nalega na notranjo stran stene kanala in le-to pritiska k znotraj ležečemu vzdolžnemu kraku prirobnice. S tem naj bi bil dosežen tesnilni učinek, ki je trajen in se ga da z izdelovalnotehničnega vidika dobro izvesti. Žmulo se da izvesti v raznih, vodoravno potekajočih velikostih (formatih). Format v vodoravni smeri tja do nasprotiležečega kraka prirobničnega profila lahko vseskozi visoko poteka. Praksa pa je pokazala, da do prižemnega in tesnilnega učinka, ki se pričakujeta zaradi specifične izvedbe prednapete žmule, ne pride.A problem is the sealing between the flange profile arms and the duct wall, because air can flow freely due to the mutual distances at which the weld points are arranged, between the inner flange profile rails and the duct wall at the front of the duct wall. In order to achieve better sealing, a kind of bead is formed into the cavity profile - starting from the front radial arm of the air duct profile - with a prestressing towards the horizontal flange arm. Inside the recessed arch of the buzzer, with a clamping fit, it rests on the inside of the channel wall and presses it against the longitudinal longitudinal arm of the flange. This is intended to achieve a sealing effect that is durable and can be well-executed from a technical point of view. The jumble can be made in different horizontal sizes (formats). The format in the horizontal direction to the opposite edge of the flange profile can be high throughout. However, the practice has shown that the clamping and sealing effects expected due to the specific implementation of the prestressed bead do not occur.
Izdelovalne tolerance pri vlečenju prirobničnih profilov niso v vsakem slučaju tako ozke, da bi bilo možno neproblematično vstavljanje pločevin stene kanala v prirobnico.The manufacturing tolerances for pulling the flange profiles are not in any case so narrow that it would be possible to insert the channel wall sheets into the flange without any problems.
Pokazalo seje, da pri premočnem prednapetju žmule kanalske pločevine ni mogoče vstaviti med žmulo in krak, temveč ona nanju zadene. Po eni plati tu ni dosežen pričakovani tesnilni učinek in po drugi sodelovanje kanalske stene in prirobničnega elementa ni učinkovito.It has been shown that in case of excessive prestressing of the groove, the canal sheet cannot be inserted between the groove and the trunk, but it hits them. On the one side, the expected sealing effect is not achieved here, and on the other, the cooperation of the channel wall and the flange element is not effective.
Če je žmula prioblikovana na prevelikem odmiku od spodnjega kraka, ni vzpostavljen prižemni in tesnilni učinek. V obeh slučajih se ugotavlja, da izumskega učinka, torej zatesnitve zračnega kanala v prirobničnem profilu, ni moč zagotoviti, saj čeprav je rešitev tehnično dobro predstavljena in premišljena, pa tehnološke možnosti pri izdelavi prirobničnih profilov prinašajo preveliko tolerančno odstopanje, da bi bil zagotovljen izumski uspeh po zadevni rešitvi.If the bead is shaped too far from the lower limb, no clamping and sealing effect is established. In both cases, it is found that the inventive effect, ie the sealing of the air duct in the flange profile, cannot be guaranteed because, although the solution is technically well-presented and thoughtful, the technological possibilities in the production of flange profiles provide too much tolerance to ensure the invention's success after the solution in question.
Izum temelji na nalogi, ustvariti prirobnični profil za prirobnično zvezo za medsebojno pritrjevanje v preseku v bistvu pravokotnih delnih kosov kanala iz pločevine, predvsem za visokotlačne napeljave za vodenje zraka, ki zagotavlja zanesljivo natančno montažo prirobničnega profila na delnem kosu zračnega kanala in s tem vzpostavlja trajno nepredušno zvezo prirobničnega profila s kosom zračnega kanala kot tudi med kosi zračnega kanala, pri čemer tesnilni učinek ostane elastičen in naj računa s tehnološkimi zahtevami po zadostni prilagodljivosti pri izdelavi prirobničnega profila in pri montaži.The invention is based on the task of creating a flange profile for a flange connection for interconnection of essentially rectangular partial pieces of a duct from sheet metal, in particular for high-pressure air ducts, which ensures reliable precise mounting of the flange profile on a partial piece of an air duct, thereby establishing a permanent airtight connection of the flange profile with the air duct piece as well as between the air duct pieces, leaving the sealing effect elastic and taking into account the technological requirements for sufficient flexibility in the flange profile fabrication and installation.
Po izumu se naloga reši s tem, da je teme v prirobnični profil vdelanega žmulnega zgiba prekrito z elastično plastjo, pri čemer ta plast na notranji strani nasprotiležečega dela kraka in elastično nalegajoče hermetično zapira konstrukcijsko predvideno režo med kračnim delom (delom kraka) nasprotiležečega kraka kot tudi temenom žmulnega zgiba.According to the invention, the problem is solved by the fact that the threads in the flange profile of the embedded gypsum joint are covered with an elastic layer, with that layer on the inside of the opposing leg portion and the elastically fitting hermetically closing the structural slit between the leg portion (limb portion) of the opposing leg also at the crown of the jugular joint.
V okviru izuma je, da je elastična plast nanesena vseskozi na teme žmulnega zgiba in povezana z nasprotiležečim delom kraka. Izvedbena oblika izuma je, da je nasproti temenu žmulnega zgiba ležeči del kraka kot tak vmesni del, ki je - premoščujoč stičišče dveh krakov - nagnjen pod določenim kotom med krakoma in povečuje stabilnost prirobničnega profila.According to the invention, the elastic layer is applied at all times to the topics of the jugular joint and connected to the opposing portion of the limb. It is an embodiment of the invention that, opposite to the crown of the sacrum joint, the supporting part of the leg is such an intermediate part, which is - bridging the intersection of two arms - inclined at a certain angle between the arms and increases the stability of the flange profile.
Izum je prednostno zasnovan, če je elastična plast na notranjo stran vmesnega dela, ležečega nasproti temenu žmulnega zgiba, vseskozi (skoznje) nanesena.The invention is preferably designed if a resilient layer is applied to the inside of the intermediate portion opposite to the crown of the jugular joint (through).
Razumna izvedbena oblika izumske rešitve je značilna po tem, da ima razsežnost elastične plasti v območju temenske točke vseskozi (skoznjo) debelino 1-5 mm. Razsežnost elastične plasti je prednostno odvisna od tega, v kolikšni meri je potrebno gibanje krakov in s tem tolerančno območje širine reže pri temenski točki žmule. Prednostno je izum nadalje zasnovan, če ima elastična plast razsežnost 2 mm, a se v okviru izumske zamisli giblje v območju 1 do 5 mm. Posebna izvedbena oblika izuma je, če je elastična plast narejena iz proti staranju odporne tesnilne mase.A reasonable embodiment of the invention is characterized in that the dimension of the elastic layer in the region of the tip point is (through) a thickness of 1-5 mm at all times. The dimension of the elastic layer depends, in the first place, on the extent to which the movement of the limbs is required, and thus the tolerance area of the width of the gap at the crown tip point. Preferably, the invention is further designed if the elastic layer has a dimension of 2 mm, but within the scope of the invention it ranges from 1 to 5 mm. A particular embodiment of the invention is where the elastic layer is made of an anti-aging sealant.
Prednostna zasnova izuma je v tem, da je tesnilna masa temperaturno obstojna vse do 100°C in ohrani svojo elastično konzistenco.An advantageous design of the invention is that the sealant is temperature resistant up to 100 ° C and retains its elastic consistency.
Izum naj v podrobnostih obrazložimo na osnovi izvedbenega primera. V priloženih listih skic kaže sl. 1 prirobnični profil v pogledu od strani, sl. 2 pa profil s sl. 1 z vstavljeno pločevino zračnega kanala.The invention should be explained in detail on the basis of an embodiment. In the enclosed sketch sheets, FIG. 1 is a side flange profile, FIG. 2 and the profile of FIG. 1 with air duct insert.
Prirobnični profil 1 je sestavljen iz dvojic krakov 2; 3; 4; 5. Dvojica krakov 2; 3 je na svojem prednjem koncu odprta, dvojica krakov 4; 5 pa je vseskozi (skoznje) povezana in na svoji zgornji strani ven potisnjena.Flange profile 1 consists of pairs of spokes 2; 3; 4; 5. Two spokes 2; 3 is open at its anterior end, two spokes 4; 5, however, is connected (through) at all times and pushed out on its upper side.
Med krakoma 2; 4 je v stičišču dvojice krakov razporejen vmesni del 9. Krak 5 je proti kraku 3 postavljen pod pravim kotom. V krak 5 je vodoravno in vzporedno s krakom 3 potekajoče vdelan žmulni zgib 7, ki sega v notranji prostor prirobničnega profila 1, ki je oblikovan med krakoma 4; 5 kot tudi vmesnim delom 9. V svoji vodoravni razsežnosti poteka žmulni zgib vzporedno s krakom 3. Med notranjo ploskvijo kraka 3 in stranskim bokom 13 žmulnega zgiba 7 je izvedeno vodilo 8. Teme 14 žmulnega zgiba 7 štrli v svoji razsežnosti do tesno ob notranjo ploskev vmesnega dela 9, ne da bi nanjo nalegalo.Between arms 2; 4, an intermediate portion 9 is arranged at the intersection of the two arms. The arm 5 is positioned at right angles to arm 3. A bead joint 7 extending horizontally and parallel to the bead 3 extends into the inner space of the flange profile 1 formed between the bead 4; 5 as well as the intermediate parts 9. In its horizontal dimension, the hinge joint extends parallel to the arm 3. The guide 8 extends between the inner surface of the arm 3 and the lateral flank 13 of the hinge joint 7. The threads 14 of the hinge joint 7 project in their dimension to close to the inner surface. of intermediate part 9 without being in contact with it.
Elastična tesnilna masa 15 povezuje teme 14 žmulnega zgiba 7 z notranjo ploskvijo vmesnega dela 9. Kraka 2; 3 potekata medsebojno v bistvu vzporedno in sta na notranjih koncih kotno zapognjena. Krak 3 se na svojem koncu kotno nagiba h kraku 2; krak 2 se kotno nagiba proč od kraka 3. Pri točki 16 oba kraka 2; 3 nalegata dotikajoče se drug na drugega. Pri natikanju prirobničnega profila na pločevino zračnega kanala gre pločevina 12 zračnega kanala sprva mimo točke 16, pri tem razpre kraka 2; 3 drugega od drugega in nato zdrsne ob stranski bok 13 žmulnega zgiba 7 v vodilo 8.The elastic sealant 15 connects the threads 14 of the joint joint 7 with the inner surface of the intermediate portion 9. of Step 2; 3 are substantially parallel to each other and are angularly folded at the inner ends. At its end, leg 3 tilts angularly to arm 2; arm 2 tilts angled away from arm 3. At point 16, both arms 2; 3 touch each other. When the flange profile is affixed to the air duct sheet, the duct 12 duct is initially past the point 16, opening the legs 2; 3 from each other and then slides along the side flank 13 of the blister joint 7 into the guide 8.
Skica sl. 2 kaže že vloženo pločevino 12 zračnega kanala v vodilu 8. Pri tem je z razprtjem krakov 2; 3 reža 11 nekoliko povečana in tesnilna masa 15 v reži 11 razvlečena. Tesnilni in prižemni učinek krakov 2; 3 pri točkah 16; 16’ kot tudi med stranskim bokom 13 žmulnega zgiba 7 in notranjo ploskvijo kraka 3 kot tudi čelno stranjo pločevine 12 zračnega kanala na notranji strani kraka 5 se sedaj v popolnosti vzpostavi s tesnilno maso 15 med temenom 14 žmulnega zgiba 7 in notranjo stranjo vmesnega dela 9.Sketch of FIG. 2 shows an already inserted sheet 12 of the air duct in guide 8. In this case, by opening the arms 2; 3 slot 11 slightly enlarged and the sealing mass 15 in slot 11 extended. Sealing and clamping effect of spokes 2; 3 at points 16; 16 'as well as between the lateral flank 13 of the blade joint 7 and the inner surface of the blade 3 as well as the front face of the sheet 12 of the air duct on the inner side of the blade 5 is now fully established by the sealing mass 15 between the dark 14 of the blade joint 7 and the inner side of the intermediate portion 9 .
S sodelovanjem tesnilnih elementov 8; 15; 16; 16’ se domala povsem izognemo puščanju zraka. Vgraditev tesnilne mase 15 v režo 11 v območju temenske točke 14 žmulnega zgiba 7 in njena trajno elastična izvedba dopušča prevzem prednostno dinamičnih nihanj. Hkrati se elastično sprejmejo izdelovalno in materialno pogojene tolerančne prekoračitve. Ureditev žmulnega zgiba 7 v svoji vodoravni razsežnosti z vzporedno z notranjo stranjo kraka 3 potekajočim stranskim bokom 13 je zaradi tega prednostna, ker je njegov odmik možen s tolerančnim območjem, ki dopušča lahko vstavljanje pločevine 12 zračnega kanala do naleženja na notranjo stran kraka 5 v območju stranskega boka.With the cooperation of sealing elements 8; 15; 16; 16 'almost completely avoid air leaks. The installation of the sealing compound 15 into the slot 11 in the area of the crown point 14 of the joint of the joint 7 and its permanently elastic design permits the assumption of preferably dynamic oscillations. At the same time, manufacturing and material tolerance exceedances are accepted elastically. The arrangement of the hinge joint 7 in its horizontal dimension with the laterally extending lateral flank 13 parallel to the inner side of the arm 3 is therefore advantageous because its displacement is possible with a tolerance zone which permits the insertion of a sheet of air duct 12 to fit on the inner side of the flap 5 in the region of the lateral flank.
