Description

Izum se odnosi na sustav priključaka za radijatore s priključcima za polazni i povratni vod. The invention relates to a connection system for radiators with connections for the supply and return lines.

Radijatori se dvocijevnim ili jednocjevnim sustavom preko razdjelnika priključuju na kotao za grijanje ili na spremnik tople vode. Kod dvocijevnog sustava se radijatori povezuju paralelno a kod jednocjevnog sustava serijski. Kao dovodne cijevi koriste se cijevi od metala ili plastične mase, a pretežno savitljive plastične cijevi koje se postavljaju odmatanjem s role. Pritom se cijevi od razdjelnika do pojedinih radijatora razvode po podu. Dovodne cijevi se postavljaju ili u toplinsku i zvučnu izolaciju koja je položena na pod ili na izolaciju te se prekrivaju podnim slojem na koji se zatim postavlja podna obloga, obično pločice. The radiators are connected to the heating boiler or to the hot water tank through a two-pipe or one-pipe system via a distributor. In the case of a two-pipe system, the radiators are connected in parallel, and in the case of a one-pipe system, they are connected in series. Pipes made of metal or plastic are used as supply pipes, mostly flexible plastic pipes that are installed by unrolling. In doing so, the pipes from the distributor to the individual radiators are spread over the floor. The supply pipes are placed either in thermal and sound insulation that is laid on the floor or on the insulation and are covered with a floor layer, on which the floor covering is then placed, usually tiles.

Priključak radijatora smještenih na zidovima prostorije na dovodne cijevi položene po podu vrši se preko spojnih cijevi od metala ili plastične mase smještenih okomito u odnosu na pod i s razmakom od zida, koje se s dovodnim cijevima u podu spajaju zavarivanjem ili navojno, a s priključcima radijatora pomoću priključne armature s integriranim zapornim ventilom. The connection of the radiators located on the walls of the room to the supply pipes laid on the floor is made through connecting pipes made of metal or plastic placed vertically in relation to the floor and with a distance from the wall, which are connected to the supply pipes in the floor by welding or threaded, and to the radiator connections using a connection fittings with an integrated shut-off valve.

Priključci radijatora s okomito iz poda do radijatora postavljenim spojnim cijevima ometaju čišćenje poda, a kod podne obloge od pločica zahtijevaju rezanje pločica što estetski loše izgleda. Daljnji nedostatak ovog poznatog sustava priključaka je posebice kod dvocijevnog sustava vrlo velik utrošak materijala uvjetovan time što se od razdjelnika do svakog radijatora moraju položiti po dvije cijevi za dovod tople vode i odtok hladne vode. Radiator connections with connecting pipes placed vertically from the floor to the radiator hinder the cleaning of the floor, and tile floor coverings require cutting the tiles, which looks bad aesthetically. A further disadvantage of this well-known system of connections is, especially in the case of a two-pipe system, a very large consumption of material due to the fact that two pipes for hot water supply and cold water discharge must be laid from the distributor to each radiator.

Kod priključaka na radijatore s vodoravno iz zida do radijatora položenom spojnom cijevi se priključne armature čiji je navojni cijevni spoj okrenut prema zidu mogu samo vrlo teško odostraga navojno spojiti s dovodnim vodovima. Zbog loše dostupnosti priključne armature, odn. navojnog spoja cijevi može vrlo lako doći do propuštanja istih. Zadatak ovog izuma bio je razvoj takvog sustava priključaka za radijatore koji bi u usporedbi s poznatim sustavom predstavljao tehničko pojednostavljenje glede smanjenja potrebnog materijala, jednostavnije i brže montaže i većeg stupnja predizrade. In the case of connections to radiators with a connecting pipe laid horizontally from the wall to the radiator, connecting fittings whose threaded pipe connection faces the wall can only be threadedly connected to the supply lines from the back with great difficulty. Due to the poor availability of connecting fittings, or the threaded connection of the pipes can very easily lead to leaks. The task of this invention was the development of such a system of connections for radiators which, compared to the known system, would represent a technical simplification in terms of reducing the required material, simpler and faster assembly and a higher degree of prefabrication.

Ovaj je zadatak prema izumu riješen sustavom priključaka za radijatore s karakteristikama iz patentnog zahtjeva 1. Sporedni patentni zahtjevi sadržavaju praktičnije i svrhovitije daljnje oblike sustava priključaka prema ovom izumu. Sustav priključaka prema ovom izuma odlikuje se pored prednosti koje proizlaze iz zadataka izuma i time što se zbog pričvršćenja spojnih cijevi smještenih između dovodnih cijevi na podu i radijatora na zidu kao i zbog polaganja ovih cijevi pod žbuku na zidu pod može bez problema čistiti, a ne dolazi do nepovoljnog utjecaja na estetski izgled čitave prostorije According to the invention, this task is solved by a connection system for radiators with the characteristics from patent claim 1. Subsidiary patent claims contain more practical and purposeful further forms of the connection system according to this invention. The system of connections according to this invention is distinguished, in addition to the advantages resulting from the tasks of the invention, by the fact that due to the attachment of the connecting pipes located between the supply pipes on the floor and the radiator on the wall, as well as due to the laying of these pipes under the plaster on the wall, the floor can be cleaned without any problems, and not there is an unfavorable influence on the aesthetic appearance of the entire room

Glavni konstrukcijski elementi sustava priključaka, konstruiranog kao dvocijevni sustav, prema crtežu 1 za radijatore 2 pričvršćene na zid 1 su: The main structural elements of the connection system, designed as a two-pipe system, according to drawing 1 for radiators 2 attached to the wall 1 are:

cijevni razdjelnici 3 od plastične mase koji se ugrađuju u polazni vod 4 i povratni vod 5, pri čemu je svakom radijatoru 2 dodijeljen jedan cijevni razdjelnik 3, zatim priključni cijevni elementi 6 s po dva paralelna plastična cijevna koljena 7 za spajanje priključka 8 polaznog voda i priključka 9 povratnog voda radijatora 2 s cijevnim razdjelnicima 3, nadalje metalni ventilski blokovi 10 za ugradnju između priključnih cijevnih elemenata 6 i radijatora 2. pipe manifolds 3 made of plastic that are installed in the supply line 4 and the return pipe 5, whereby each radiator 2 is assigned one pipe manifold 3, then connecting pipe elements 6 with two parallel plastic pipe elbows 7 each for connecting the connection 8 of the supply line and connection 9 of the return line of the radiator 2 with pipe manifolds 3, further metal valve blocks 10 for installation between the connecting pipe elements 6 and the radiator 2.

Cijevni razdjelnici 3 prikazani na crtežima 2 do 5 pričvršćuju se na betonski pod 11 i polažu u toplinsku i zvučnu izolaciju 12 na koju se nanosi podni sloj 13, na koji se zatim polažu tapison 14, drveni pod ili pločice. Pipe manifolds 3 shown in drawings 2 to 5 are attached to the concrete floor 11 and laid in thermal and sound insulation 12, on which the floor layer 13 is applied, on which carpet 14, wooden floor or tiles are then laid.

Cijevni razdjelnici 6 imaju dva paralelna prolazna kanala 15,16 za priključak na polazni vod 4 i na povratni vod 5 kao i dvije priključne cijevi 17,18 postavljene poprečno na prolazne kanale 15,16, pri čemu se priključna cijev 17 odvaja od prvog prolaznog kanala 15, a druga je cijev 18 spojnim kanalom 19, koji prolazi kroz prvi prolazni kanal 15, priključena na drugi prolazni kanal 16. Pipe splitters 6 have two parallel through channels 15,16 for connection to the supply line 4 and to the return line 5, as well as two connection pipes 17,18 placed transversely on the through channels 15,16, whereby the connection pipe 17 is separated from the first through channel 15, and the second pipe 18 is connected to the second passage channel 16 through the connecting channel 19, which passes through the first passage channel 15.

Cijevni razdjelnici 3 su opremljeni s dva dodatna priključna nastavka 20 koji na strani cijevnog razdjelnika 3 koja se nalazi nasuprot priključnih cijevi 17,18 poprečno graniče s drugim prolaznim kanalom 16. The pipe manifolds 3 are equipped with two additional connecting extensions 20 which, on the side of the pipe manifold 3 opposite the connecting pipes 17, 18, border the second through channel 16 transversely.

Priključni nastavci 20 cijevnih razdjelnika 3 mogu se u slučaju potrebe navrtati da bi se priključile spojne cijevi prema prolaznom kanalu 16. The connection extensions 20 of the pipe manifolds 3 can be screwed if necessary to connect the connecting pipes to the passage channel 16.

Na crtežu 1 shematski prikazani spoj, prolaznih kanala 16 priključenih npr. na povratni vod 5 dvaju cijevnih razdjelnika 3 preko priključne cijevi 21, koja međusobno spaja dva probušena priključna nastavka 20 cijevnog razdjelnika 3, potreban je u onim slučajevima kad su oba cijevna razdjelnika 3 zbog tako malog razmaka između dva radijatora 2 smještena toliko blizu jedan drugom da se zbog nedostatka mjesta za aparat za varenje mogu međusobno spojiti samo prolazni kanali 15 koji se priključuju na polazni vod 4, i to pomoću ravnog cijevnog elementa od plastične mase koji se zavaruje u izlaz jednog kanala i u ulaz drugog kanala. Izlazni kraj prolaznog kanala 16 jednog cijevnog razdjelnika 3 i ulazni kraj prolaznog kanala 16 iza priključenog cijevnog razdjelnika 3 zatvaraju se plastičnim čepovima 23 koji se zavaruju u kanale. In drawing 1, the schematically shown connection of the passage channels 16 connected, for example, to the return line 5 of two pipe distributors 3 via the connecting pipe 21, which connects the two perforated connection extensions 20 of the pipe distributor 3, is necessary in those cases when both pipe distributors 3 are such a small distance between the two radiators 2 located so close to each other that due to the lack of space for the welding apparatus, only the passing channels 15 can be connected to each other, which are connected to the starting line 4, by means of a flat plastic tube element that is welded to the outlet of one channel and into the input of another channel. The outlet end of the passage channel 16 of one pipe distributor 3 and the inlet end of the passage channel 16 behind the connected pipe distributor 3 are closed with plastic caps 23 that are welded into the channels.

Oba cijevna koljena 7 priključnih cijevnih elemenata 6 za povezivanje radijatora 2 na cijevne razdjelnike 3 imaju odstojne uloške 24 pomoću kojih se cijevna koljena 7 navarena na priključne cijevi 17,18 razdjelnika 3 pričvršćuju na zid 1 prije nanošenja žbuke 25. Both pipe elbows 7 of the connecting pipe elements 6 for connecting the radiator 2 to the pipe manifolds 3 have spacers 24 with which the pipe elbows 7 welded to the connection pipes 17,18 of the manifold 3 are attached to the wall 1 before applying plaster 25.

Ventilski blokovi 10 za ugradnju između priključnih cijevnih elemenata 6 i radijatora 2 opremljeni su s dva kutna ventila 26, s integriranim steznim spojnicama za pričvršćenje blokova 10 na iz zida 1 stršeće vodoravne krajeve 7a oba cijevna koljena 7 priključnih cijevnih elemenata 6, zatim s navojnim cijevnim spojevima 27 za navojno pričvršćenje blokova 10 na priključke 8,9 radijatora za polazni vod 4 i povratni vod 5. The valve blocks 10 for installation between the connecting pipe elements 6 and the radiator 2 are equipped with two corner valves 26, with integrated clamps for attaching the blocks 10 to the horizontal ends 7a protruding from the wall 1 of both pipe elbows 7 of the connecting pipe elements 6, then with threaded pipe connections 27 for screwing the blocks 10 to the connections 8,9 of the radiator for the supply line 4 and the return line 5.

Oba kućišta 28 ventilskih blokova 10, međusobno povezana uloškom 29, oblikovana su kao T-elementi. Na kraju 30 svakog kućišta 28 ventila, a koji kraj se natiče na cijevno koljeno 7 priključnog cijevnog elementa 6 oblikovan je vijenac 31 unutrašnjeg promjera koji odgovara vanjskom promjeru cijevnog koljena 7. Na vijencu 31 leži stezni i brtveni prsten 32 od gume ili sl. elastičnog materijala. U kraju 34 provrta 33 svakog kućišta 28 ventila, a koji kraj 34 se nalazi nasuprot vijenca 31 i opremljen je unutrašnjim navojem, postavljena je navojna čahura 36, zabrtvljena pomoću 0-prstena 35 prema kućištu 28, s vijčanom glavom 37 za pritezanje stezne čahure 38, koja obuhvaća kraj 7a cijevnog koljena 7, na stezni i brtveni prsten 32 koji leži na kraju cijevnog koljena 7a. Both housings 28 of the valve blocks 10, connected to each other by the insert 29, are shaped as T-elements. At the end 30 of each valve housing 28, which end abuts the pipe bend 7 of the connecting pipe element 6, a ring 31 is formed with an inner diameter that corresponds to the outer diameter of the pipe bend 7. On the ring 31 rests a clamping and sealing ring 32 made of rubber or similar elastic material. material. In the end 34 of the bore 33 of each valve housing 28, and which end 34 is located opposite the crown 31 and is equipped with an internal thread, a threaded sleeve 36 is placed, sealed by means of an 0-ring 35 towards the housing 28, with a screw head 37 for tightening the clamping sleeve 38. , which includes the end 7a of the pipe elbow 7, to the clamping and sealing ring 32 that lies on the end of the pipe elbow 7a.

Navojna čahura 36 djeluje preko dva prstenasta segmenta 39 na steznu čahuru 38. Prstenasti segmenti 39 tvore prolazne otvore 40 za polaznu vodu koja preko jednog cijevnog koljena 7 i stezne čahure 38 ulazi u kućište 28 jednog kutnog ventila 26 te izlazi iz kućišta 28 jednog kutnog ventila 26 kroz priključni nastavak 41 smješten okomito na prolazni otvor jednog kutnog ventila 26 i ulazi u priključak 8 za dolazni vod 4 na radijatoru 2, odn. kod drugog kutnog ventila 26 za povratnu vodu koja preko priključka 9 na radijatoru 2 za povratni vod 5 i preko priključnog nastavka 41 ulazi u kućište 28 ventila te preko stezne čahure 38 i drugog cijevnog koljena izlazi iz kućišta 28 ventila. The threaded sleeve 36 acts via two annular segments 39 on the clamping sleeve 38. The annular segments 39 form through openings 40 for the starting water, which enters the housing 28 of one angle valve 26 and exits the housing 28 of one angle valve via one pipe elbow 7 and clamping sleeve 38 26 through the connection extension 41 located perpendicular to the passage opening of one angle valve 26 and enters the connection 8 for the incoming line 4 on the radiator 2, or. at the second angle valve 26 for the return water, which enters the valve housing 28 through the connection 9 on the radiator 2 for the return line 5 and through the connecting piece 41, and exits the valve housing 28 through the clamping sleeve 38 and the second pipe elbow.

U navojnoj čahuri 36 nalazi se prema njoj zabrtvljeni navojni čunjasti zapornik 42 za otvaranje i zatvaranje sjedišta 43 ventila postavljenog kroz steznu čahuru. U krajeve oba cijevna koljena 7 priključnog cijevnog elementa 6 koji se nalaze u ventilskom bloku 10 uložene su potporne čahure 44 od metala. In the threaded sleeve 36, there is a threaded conical stopper 42 sealed against it for opening and closing the seat 43 of the valve placed through the clamping sleeve. Support bushings 44 made of metal are inserted into the ends of both pipe elbows 7 of the connecting pipe element 6, which are located in the valve block 10.

Prilikom instaliranja sustava priključaka u nekoj prostoriji se polazni vod 4 i povratni vod 5 polažu po odsječcima od razvodnog ormarića 45 po podu 11 do pojedinih cijevnih razdjelnika 3 raznih radijatora 2, a pojedini odsječci cijevi 4a, 5a polaznog voda 4 i povratnog voda 5 se zavaruju na cijevne razdjelnike 3. Zatim se priključni cijevni elementi 6 s po dva cijevna koljena 7, čiji su gornji krajevi 7a zatvoreni, zavaruju na priključne cijevi 17,18 cijevnih razdjelnika 3. Nakon toga se cijevni razdjelnici 3 pričvršćuju na pod 11. a cijevni elementi 6 na zidove 1. Zatim se na pod 11 polaže toplinska i zvučna izolacija 12, nanosi podni sloj 13 a zidovi 1 žbukaju, tako da priključni cijevni elementi 6 nestaju pod žbukom 25, a iz zidova 1 strše još samo gornji krajevi 7a cijevnih koljena 7. When installing the connection system in a room, the supply line 4 and the return line 5 are laid in sections from the distribution cabinet 45 on the floor 11 to individual pipe distributors 3 of various radiators 2, and individual sections of pipes 4a, 5a of the supply line 4 and return line 5 are welded to the pipe distributors 3. Then the connecting pipe elements 6 with two pipe elbows 7 each, whose upper ends 7a are closed, are welded to the connection pipes 17,18 of the pipe distributors 3. After that, the pipe distributors 3 are attached to the floor 11. and the pipe elements 6 on the walls 1. Then heat and sound insulation 12 is laid on the floor 11, the floor layer 13 is applied, and the walls 1 are plastered, so that the connecting pipe elements 6 disappear under the plaster 25, and only the upper ends 7a of the pipe elbows 7 protrude from the walls 1. .

Nakon toga se na zidove 1 ovješuju radijatori 2, te na odstojnu dimenziju 46 radijatorskih priključaka 8,9 od zida 1 skraćuju krajevi 7a na cijevnim koljenima, potporne čahure 44 postavljaju u krajeve 7a cijevnih koljena 7, ventilski blokovi 10 pojedinih radijatora 2 postavljaju do graničnika na krajeve 7a cijevnih koljena 7 za priključenje polaznog voda 4 i povratnog voda 5, a nakon ulaganja brtvenih prstena postavljaju preturne matice 47 navojnih cijevnih spojeva 27 ventilskih blokova 10 na radijatorske priključke 8,9 i pritezanjem navojnih čahura 36 u ventilskim blokovima 10 uspostavlja stezni spoj ventilskih blokova 10 s krajevima 7a cijevnih koljena 7 priključnih cijevnih elemenata. After that, the radiators 2 are hung on the walls 1, and the ends 7a of the pipe elbows are shortened to the distance dimension 46 of the radiator connections 8,9 from the wall 1, the support sleeves 44 are placed in the ends 7a of the pipe elbows 7, the valve blocks 10 of individual radiators 2 are placed up to the stop on the ends 7a of the pipe elbows 7 for connecting the supply line 4 and the return line 5, and after inserting the sealing rings, they place the turn nuts 47 of the threaded pipe connections 27 of the valve blocks 10 on the radiator connections 8,9 and by tightening the threaded bushings 36 in the valve blocks 10, a clamping connection is established of valve blocks 10 with ends 7a of pipe elbows 7 connecting pipe elements.
