Oblasť technikyTechnical field
Vynález sa týka nátrubku z umelej hmoty, kde na telese nátrubku je vytvarované jednak prípojné hrdlo na upevnenie prípojnej trubky, poprípade armatúry, a jednak je na ňom vytvarovaná úložná plocha na navarenie nátrubku do plášta hlavného potrubia,The invention relates to a plastic sleeve, wherein on the sleeve body, on the one hand, a connection piece is formed for fastening the connection pipe or a fitting, and on the other hand, there is a bearing surface for welding the sleeve into the casing of the main pipe.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Nátrubky tohto typu, zhotovené obvykle s teplom vytvrdí teľnej umelej hmoty, bývajú na umelohmotné potrubia ' navarené prevažne . pomocou ručných zváracích nástrojov. Pri týchto nástrojoch plášťa potrubia stranách tŕňa ohrevné telieska nátrubkom nástroj, priložený sú sa účelom ohriatia nátrubku po obidvoch teplo naskrutkované a úložnej plochy privádzajúcehoPipes of this type, usually made with heat-curing plastic, tend to be welded predominantly to plastic pipes. using manual welding tools. In these pipe casing tools, the heating element spigots are connected to the sides of the heating element by means of the sleeve of the tool, provided for the purpose of heating the sleeve after both heat-screwed and bearing surfaces of the supplying
Pri zhotovení svarového spoja medzi a hlavným potrubím je najprv ručný zvárací ohriaty na teplotu cca S60 stupňov C, potrubia, čím dôjde v na vonkajší plášť mieste zvaru k nataveniu, resp.plastifikácii vonkajšej vrstvy umelej hmoty. Bez prerušenia ohrevu plochy potrubia v mieste zvaru, t.j. pri stálom styku ručného zváracieho nástroja s potrubím, je následne nasadený' nátrubok na ohrevné teliesko, ohriate teplotu cca S60 stupňov C, čím dôjde k resp. plastifikäcii dosadacej navarovany rovnako na nataveniu, nátrubku. Potom plochy je ručný zvárací nástroj odstránený a nátrubok je svojou plastifikovanou dosadacou plochou pritlačený na plastifikovanú vonkajšiu plochu plášťa potrubia. Po tomto procese zvárania, pri ktorom je nutné ponechať určitý čas na vychladnutie zvarového spoja, je dalej na úplné zhotovenie odbočky, ktorá môže byť rovnako zosilnená kovovým púzdrom, treba prevŕtať dno navareného nátrubku, vrátane steny potrubia.When making the weld joint between and the main pipe, the manual welding is first heated to a temperature of approx. S60 degrees C, the pipe, whereby the outer shell of the weld will melt or plasticize the outer layer of plastic. Without interrupting the heating of the pipe surface at the weld site, i. When the hand-held welding tool is in constant contact with the pipe, the nozzle is then placed on the heating element, which is heated to a temperature of approx. S60 degrees C. plasticization of the seating welded equally to the fusion, sleeve. Then the surfaces are removed by the hand welding tool and the sleeve is pressed by its plasticized bearing surface onto the plasticized outer surface of the pipe jacket. After this welding process, in which it is necessary to allow some time to cool down the weld joint, to complete the branching, which can also be reinforced with a metal sleeve, the bottom of the welded sleeve, including the pipe wall, must be drilled.
V praxi sa však ukazuje, že pri použití ručného zváracieho nástroja nie je v dôsledku dĺžok ohrevných teliesok dosahované rovnomerného dosadnutia nástroja na vonkajší povrch potrubia. Tým dochádza na nerovnomerné natavenie, resp. plastifikáciu vonkajšej vrstvy z umelej hmoty v mieste zvaru a teda aj k nehomogénnemu zvarovému spoju medzi potrubím a nátrubkom. Takto vytvorené zvarové spojenie môže byť príčinou netesností v potrubnom systéme,pričom pri pôsobení vonkajšej sily vzniká rovnako nebezpečie odtrhnutia navareného nátrubku. <In practice, however, it appears that when using a manual welding tool, due to the lengths of the heating elements, a uniform bearing of the tool on the outer surface of the pipe is not achieved. This results in uneven melting, respectively. plasticizing the outer plastic layer at the weld site and hence also to the inhomogeneous weld joint between the pipe and the sleeve. Such a welded connection can cause leakage in the piping system and the risk of tearing off the welded sleeve also results from external force. <
Podstata vynálezuSUMMARY OF THE INVENTION
Vynález si kladie základnú úlohu dalej zlepšiť tento nátrubok na zhotovenie odbočky v potrubí, najmä so zreteľom na jeho funkčné a bezpečné privarenie na potrubie z umelej hmoty.The invention aims to further improve this sleeve for making a branch in a pipe, particularly with regard to its functional and safe welding to a plastic pipe.
Táto úloha je podľa vynálezu vyriešená nátrubkom podľa .vý'znakov hlavného patentového nároku.This object is achieved according to the invention by a sleeve according to the features of the main claim.
Vedľajšie patentové nároky potom obsahujú dalšie výhodné uskutočnenie nátrubku podľa vynálezu.The subclaims then comprise a further preferred embodiment of the sleeve according to the invention.
Podstata riešenia pritom spočíva v tom, že úložná plocha telesa nátrubku je vytvorená v tvare navarovacieho hrdla, ktoré je usporiadané koaxiálne s prípojným hrdlom pre odbočnú trubku. Toto navarovacie hrdlo pritom zaisťuje tesné a voči pôsobeniu vonkajších síl odolné svarové spojenie nátrubku s hlavným potrubím.The principle of the solution here is that the bearing surface of the sleeve body is designed in the form of a welding spigot which is arranged coaxially with the connection spigot for the branch pipe. In this case, the welding connection ensures a tight and resistant to external forces, the weld connection of the sleeve to the main pipe.

Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Mavarovací nátrubok 1 s priechodzím otvorom SI zhotoveným z umelej hmoty určený na vytvorenie odbočky v hlavnom potrubí S zhotovenom rovnako z umelej hmoty, je opatrený prípojným hrdlom 4, vytvarovaným na telese nátrubku 3, do ktorého je navarená ‘ odboôná trubka 5 z umelej hmoty.The weld sleeve 1 with a plastic-made through hole S1 intended to form a branch in the main pipe S made of plastic is also provided with a connection socket 4 formed on the sleeve body 3 into which the plastic branch pipe 5 is welded.
Na valcovej navarovacej, resp.dosadacej ploche 6 telesa nátrubku je dalej koaxiálne s prípojným hrdlom 4 vytvarované navarovacie hrdlo 7 .On the cylindrical welding or seating surface 6 of the sleeve body, a welding socket 7 is also formed coaxially with the connection socket 4.
hrdlo 7 nátrubku 1 je pri procese do príslušného otvoru 9, ktorý je 8 hlavného potrubia S, pričom na 10 hlavného potrubia S je súčasne 'plocha 6 telesa nátrubku-3 .' 'the neck 7 of the sleeve 1 is in the process into the corresponding opening 9, which is 8 of the main pipe S, with 10 of the main pipe S simultaneously having a surface 6 of the body of the sleeve-3. '
Navarovacie zvárania vsadené vytvorený v stene vonkajšom plášti navarená dosadaciaWelding welded welding formed in the wall of the outer casing welded seating
DÍžka 11 navarovacieho hrdla 7 je pritom väčšia ako hrúbka 18 steny 8 hlavného potrubia S. Tým je zaručená tesnosť zvarového spoja medzi nátrubkom i a hlavným potrubím S, a to pri vyskytujúcom sa vyššom tlaku, resp. teplote média prúdiacom ako v hlavnom potrubí S, tak aj v odbočnej trubke 5 .The length 11 of the welding sleeve 7 is thereby greater than the thickness 18 of the wall 8 of the main pipe S. This ensures the tightness of the weld joint between the sleeve 1 and the main pipe S at higher pressure or higher pressure. the temperature of the medium flowing in both the main pipe S and the branch pipe 5.
Ako je znázornené na obr. S, na zhotovenie zvarového spoja medzi nátrubkom i a hlavným potrubím 8 je použitý tu len zčasti znázornený ručný elektrický zvárací nástroj 88, na ktorého tŕň 13 je zo spodnej strany 15a naskrutkováné ohrevné teliesko 14.ktoré má rovnaký tvar ako spodná časť 1 telesa nátrubku 3 obsahujúca navarovacie hrdlo 7 . Ručný zvárací nástroj 88, ohriaty na teplotu tavenia umelej hmoty, je potom svojim ohrevným telieskom 14 vsadený do napred zhotoveného otvoru 9 v stene 8 hlavného potrubia 8, do ktorého má byt nátrubok 1 navarený. Po vsadení ohriateho tŕňa 15 ohrevného telieska 14 do otvoru 9 a dosadnutia nahriatej plochy 17 ohrevného telieska 14 na vonkajší plást 10 hlavného potrubia S, dôjde k nataveniut resp. plášti f ikáci i povchovej .steny 16 otvoru 9 a časti vonkajšieho plášťa 10 hlavného potrubia 8, kde má byt nátrubok 1 navarený.As shown in FIG. S, only a partially illustrated hand-held electric welding tool 88 is used for making the weld joint between the sleeve 1 and the main pipe 8, the mandrel 13 having a heater 14 screwed from the bottom 15a which has the same shape as the lower part 1 of the sleeve body 3 Welding socket 7. The hand welding tool 88, heated to the melting temperature of the plastic, is then inserted by its heating element 14 into a pre-formed opening 9 in the wall 8 of the main pipe 8 into which the sleeve 1 is to be welded. After insertion of the heated mandrel 15 of the heating bodies 14 in the opening 9 and the abutment surface 17 by heating of the heating bodies 14 of the outer jacket 10 with the main line, there is a glaze or t. the outer wall 10 of the main pipe 8 where the sleeve 1 is to be welded.
V ďalšej fáze je na ohrevné teliesko 18, naskrutkované na vrchnej strane 15b tŕňa 13, nasadený nátrubok I . V ohrevnom teliesku 18 je pritom vyhĺbený otvor 19, ktorý svojim tvarom zodpovedá tvaru navarovaeieho hrdla 7 nátrubku 1, pričom vrchná čast ohrevného telieska 18 tvorí zároveň ohrevnú plochu 30 na nahriatie dosadacej plochy 6 nátrubku 1 na nahriate ohrevné teliesko 18 tak dôjde k nataveniu, resp. plastifikácii vonkajšieho povrchu navarovaeieho hrdla 7 a dosadacej plochy 6 .In the next phase, a sleeve I is fitted to the heating element 18 screwed on the top side 15b of the mandrel 13. In the heating element 18, a hole 19 is recessed, which corresponds to the shape of the welding socket 7 of the sleeve 1, the upper part of the heating element 18 forming at the same time a heating surface 30 for heating the seating surface 6 of the sleeve 1. . plasticizing the outer surface of the weld-in sleeve 7 and the bearing surface 6.
Následne je ručný zvárací nástroj 33 vybraný z otvoru 9 hlavného potrubia 3 a súčasne je z ohrevného telieska 1S odobraný nátrubok 1, ktorý je potom ručne zatlačený do hlavného potrubia 3. Tým dôjde k styku nataveného, resp. plášti fikovaného vonkajšieho povrchu navarovaeieho hrdla 7 nátrubku 1 s rovnako natavenou resp. plastifikovanou povrchovou stenou 16 otvoru 9 hlavného potrubia S a natavené,resp. plastifikované dosadacie plochy 6 nátrubku .1 s vonkajším plášťom 10 hlavného potrubia 3, a tým ' k vzájomnému zvareniu nátrubku 1 s hlavným potrubím 3, Subsequently, the hand welding tool 33 is removed from the opening 9 of the main pipe 3 and at the same time the sleeve 1 is removed from the heating element 1S, which is then manually pushed into the main pipe 3. of the fictitious outer surface of the welded-on sleeve 7 of the sleeve 1 with the same melted or welded sleeve. a plasticized surface wall 16 of the opening 9 of the main pipe S and melted respectively. plasticized seating surfaces 6 of the sleeve 1 with the outer casing 10 of the main pipe 3, and thereby to weld the sleeve 1 to the main pipe 3 relative to each other,
