Description
DK 158020 BDK 158020 B
Opfindelsen angår en opslidset rørformet isolationsskal, især til isolation af rør, f.eks. varmt- og.koldtvandsledninger.The invention relates to a slotted tubular insulation shell, in particular for pipe insulation, e.g. hot and cold water lines.
Ved hjælp af sådanne isolationsskaller kan der opnås en foreskreven varmeisolation, uden at der stilles væsentlige krav til montørernes 5 dygtighed, ligesom man kan opnå forholdsvis korte montagetider på selve stedet. De nævnte isolationsskaller fremstilles fortrinsvis af opskummet plast. Hvis der anvendes skumplast med lukkede porer, er isolationsskallerne som følge af deres uigennemtrængelighed for vanddamp også anvendelige til isolation af kolde rørledninger. En 10 forudsætning for, at varmeisolationexi forbliver uændret, er ganske vist, at den opslidsede isolationsskal ved montagen lukkes damptæt.With the help of such insulation shells, a prescribed heat insulation can be obtained without making any significant demands on the skill of the installers 5, as well as obtaining relatively short installation times at the site itself. Said insulation shells are preferably made of foamed plastic. If foam pores with closed pores are used, the insulation shells due to their water vapor impermeability are also useful for cold pipe insulation. A prerequisite for heat insulation exi remains unchanged is that the slotted insulation shell is closed vapor-proof at installation.
Ifølge en kendt løsning omsluttes den monterede opslidsede isolationsskal med et for damp uigennemtrængeligt plasthylster, som lukkes mekanisk ved hjælp af en lynlås. Dette plasthylster kan være fast-15 limet på isolationsskallen, eller det kan ved montagen anbringes løst omkring skallen. I alle tilfælde vil anvendelsen af en sådant plasthylster væsentligt fordyre fremstillingen af isolationsskallerne.According to a known solution, the mounted slotted insulation shell is enclosed with a vapor-impermeable plastic casing, which is closed mechanically by means of a zipper. This plastic casing may be glued to the insulation shell or it may be loosely mounted around the shell upon assembly. In all cases, the use of such a plastic casing will significantly distort the manufacture of the insulation shells.
Ved opfindelsen gås der ud fra en isolationsskal af den omhandlede art af opskummet polyolefin, fortrinsvis befugtet polyethylenskum, og 20 med en med flere læber forsynet lynlås til åbning og lukning af opslidsningen, og isolationsskallen ifølge opfindelsen er ejendommelig ved, at plastlukket er en lynlås, der kan åbnes og lukkes uden brug af værktøj, at lynlåsen er gjort gastæt ved hjælp af flere ind i hinanden gribende tætningslæber, og at lynlåsen umiddelbart er på-25 svejset isolationslegemet. En sådan direkte påsvejsning er muliggjort ved, at isolationslegemet er af skumplast med lukkede celler. Befugtet polyolefinskum er for øjeblikket det eneste kendte materiale, der både er svejseligt, og som samtidig har sådanne spærreegenskaber og mekaniske egenskaber, at det på trods af, at det er billigt at 30 fremstille, giver en særdeles god isolation. Ved den direkte påsvej-ning af lynlåsen undgår man anvendelse af et specielt plasthylster, hvilket dels billiggør fremstillingen af isolationsskallen og dels letter monteringen af isolationsskallen sammenlignet med det tilfælde. hvor der anvendes et løst plasthylster.The invention assumes an insulation shell of the present type of foamed polyolefin, preferably wetted polyethylene foam, and a multi-lip zipper for opening and closing the slit, and the insulating shell according to the invention is characterized in that the plastic closure is a zipper, it can be opened and closed without the use of tools, that the zipper is made gas-tight by means of several interlocking sealing lips and that the zipper is immediately welded to the insulating body. Such direct welding is made possible by the insulating body being of closed cell foam plastic. Wetted polyolefin foam is currently the only known material which is both weldable and which at the same time has such barrier properties and mechanical properties that, despite being cheap to manufacture, provides an extremely good insulation. The direct welding of the zipper avoids the use of a special plastic casing, which partly lowers the production of the insulation shell and partly facilitates the installation of the insulation shell compared to the case. where a loose plastic casing is used.
