Frembringelsens anvendelsesområdeScope of production

Med stålring monteret på press-muffe opnås at kunne presse en press-muffe ind til en mindre diameter på en måde så en "almindelig” VVS press-muffe beregnet for samling af stålrør, kan skabe en samling til plastrør, der kan modstå samme indvendige hydrauliske tryk som samling af stålrør ved at stålringen har en godsykkelse, så indvendig diameter omkring plastrøret kan reduceres tilstrækkeligt for at kunne modstå det aktuelle vædsketryk.With a steel ring mounted on a press-sleeve, it is possible to push a press-sleeve into a smaller diameter in a way that a "regular" plumbing press-sleeve designed for the assembly of steel pipes can create a joint for plastic pipes that can withstand the same interior hydraulic pressures such as the assembly of steel pipes by the steel ring having a freight seam, so that the inner diameter around the plastic pipe can be sufficiently reduced to withstand the current fluid pressure.

Stålringen er fortrinsvis udformet så den kan afmonteres efterfølgende med fingrene eller en skruetrækker, så den ikke skæmmer udseendet efter montering, ved at være opslidset i langsgående retning.The steel ring is preferably designed so that it can be subsequently dismantled with the fingers or a screwdriver so that it does not damage the appearance after installation by being longitudinally slit.

Kendt teknik I VVS branchen er samling af fortrinsvis rustfrie rør, efterhånden en meget udbredt, stabil og billig rør-samleform, der erstatter skruesamlinger i forskellige udførelser. Dette system er videreudviklet og forfinet til samling af stålrør forbindelse befugtnings- og køleanlæg fortrinsvis i forbindelse med drivhuse og animalsk produktion. Mange huse er lange og meget velegnede til montering med stålrør, der er selvbærende.Prior Art In the HVAC industry, assembly of preferably stainless steel pipes is gradually a widely used, stable and inexpensive pipe assembly that replaces screw joints in various designs. This system is further developed and refined to assemble steel pipe connection wetting and cooling systems, preferably in connection with greenhouses and animal production. Many houses are long and very suitable for self-supporting steel pipes.

Plastrør til "almindelig” lavtryksvædske samles ligeledes med mange forskellige former for press-fittings, der specialfremstilles til formålet.Plastic pipes for "ordinary" low pressure fluid are also assembled with many different types of press fittings specially made for the purpose.

Det tekniske problem Når de 2 systemer, stålrør og plastrør skal kombineres og skal modstå højt tryk på måske 100 bar, opstår der problemer med overgange, fittings m.m. der ikke findes på markedet. De 2 systemer, stålrør og plastrør, kombineres typisk i ”små” områder som stikledninger, omkring luftindblæsningsenheder, ved tilslutning i vanskeligt tilgængelige områder og generelt, hvor der ikke er regelmæssig mulighed for ophængning af rør. Her er det overordentligt praktisk at kunne benytte plastrør i forlængelse af stålrør.The technical problem When the 2 systems, steel pipes and plastic pipes have to be combined and withstand high pressure of maybe 100 bar, problems with transitions, fittings and the like occur. that does not exist on the market. The two systems, steel pipes and plastic pipes, are typically combined in "small" areas such as plug lines, around air supply units, when connected in difficult-to-reach areas and generally where there is no regular possibility of pipe hanging. Here it is extremely practical to be able to use plastic pipes in extension of steel pipes.

Den nye teknikThe new technique

Med den nye stålring er det blevet muligt at kombinere stålrør og plastrør, herunder montere plastrør direkte i "normale” press-fittings uden at skulle benytte dyre og 2 DK 2013 00023 U3 komplicerede skæreringsfittings, overgange eller andre former for pressfittings specialfremstillet for plastrør.With the new steel ring it has become possible to combine steel pipes and plastic pipes, including mounting plastic pipes directly in "normal" press fittings without having to use expensive and complicated cutting fittings, transitions or other types of press fittings specially made for plastic pipes.

Den tekniske virkningThe technical impact

Med de meget simple press-fittings til stålrør er det muligt at samle plastrør med de samme fittings blot ved at supplere med den "simple” stålring, der sikrer at samlingen modstår samme indvendige hydrauliske tryk for såvel stålrør som plastrør.With the very simple press fittings for steel pipes, it is possible to assemble plastic pipes with the same fittings simply by supplementing with the "simple" steel ring, which ensures that the joint withstands the same internal hydraulic pressure for both steel pipes and plastic pipes.

Claims

2 DK 2013 00023 U3 With a steel ring mounted on a press sleeve, it is possible to push a press sleeve in to a smaller diameter in a way that a "regular" plumbing press sleeve intended for connection of steel pipes can create a joint for plastic pipes, which can withstand the same internal hydraulic pressure as the assembly of steel pipes and is new in that the steel ring has a good thickness, so that the inside diameter around the plastic pipe can be sufficiently reduced to withstand the current fluid pressure.2 The steel ring is preferably designed so that it can be subsequently dismantled according to claim 1 and is new by being longitudinally slit.
