Description

Rørfittings for vannledninger. Pipe fittings for water lines.

Foreliggende oppfinnelse angår rør-fittings for vannledninger og spesielt fittings beregnet i forbindelse med plastledninger. The present invention relates to pipe fittings for water pipes and in particular fittings intended for use with plastic pipes.

Ulempen ved plastledninger er at The disadvantage of plastic cables is that

disse ikke er elektrisk ledende, slik at når vannet fryser i slike plastledninger om vinteren har man vanskeligheter forbun-det med opptining av disse plastrør. Vi-dere representerer slike plastvannlednin-ger en annen ulempe, nemlig at enkelte steder, f. eks. på gårder på landet, er vannledninger som f. eks. fører til en brønn den eneste gode jordledning som huset har. Når disse vannledninger er-stattes med ledninger av plast, mister man jordforbindelsen og man får øket fare ved elektriske overledninger og ved lynnedslag. these are not electrically conductive, so that when the water freezes in such plastic pipes in winter, there are difficulties associated with thawing these plastic pipes. We-you, such plastic water pipes represent another disadvantage, namely that in some places, e.g. on farms in the country, water pipes such as leads to a well, the only good ground wire that the house has. When these water pipes are replaced with plastic pipes, the earth connection is lost and there is an increased risk of electrical overhead wires and lightning strikes.

Foreliggende oppfinnelse tar sikte på The present invention aims at

å oppheve disse ulemper ved å anbringe en elektrisk ledende tråd inne i røret. Vanske-ligheten har imidlertid vært å føre denne tråden inn eller ut av ledningen og det er spesielt en anordning for dette som løses ifølge foreliggende oppfinnelse. to cancel these disadvantages by placing an electrically conductive wire inside the tube. The difficulty, however, has been to lead this wire into or out of the wire, and there is in particular a device for this which is solved according to the present invention.

Ifølge oppfinnelsen gjøres dette ved at According to the invention, this is done by

det i en passende rørfitting anbringes et gjenget gjennomgående hull uavhengig av fittingens øvrige åpninger og at det i dette gjengede hull er utformet et spor i veggen, hvori det kan opptas en elektrisk ledende tråd som føres inn i røret. Tråden kan derved gå i dette spor og festes og hullet lukkes ved hjelp av en skrue, og det hele tettes til ved at det mellomrom skruens hode og fittingen anbringes passende pakninger. I til- a threaded through-hole is placed in a suitable pipe fitting independently of the fitting's other openings and that in this threaded hole a groove is formed in the wall, in which an electrically conductive wire can be received and fed into the pipe. The wire can thereby go into this groove and be fixed and the hole closed with the help of a screw, and the whole thing is sealed by placing suitable gaskets between the screw's head and the fitting. In to-

slutning til denne anordning kan det vi-dere på rørfittingen være anordnet en kontaktskrue for tilknytning til en ytre ledning og strømkilde. connection to this device, a contact screw can also be arranged on the pipe fitting for connection to an external wire and power source.

For at oppfinnelsen lett skal kunne forståes, skal den i det følgende forklares ved hjelp av tegningen, som viser et delvis snitt gjennom en rørfitting og et plastrør. In order for the invention to be easily understood, it will be explained in the following with the help of the drawing, which shows a partial section through a pipe fitting and a plastic pipe.

Fittingen 1 er forsynt hensiktsmessig med en vorte eller fortykning 2, slik at godset her blir tilstrekkelig tykt til anordning av et gjennomgående hull 3. I hullets vegg er det anordnet et spor 4 hvori det kan anbringes en elektrisk ledende ledning 5 som føres over til en kontaktskrue 6 som også kan være anordnet i en vorte 7 på rørfittingen. Hullet 3 tettes igjen ved hjelp av en skrue, idet det mellom skruens hode 8 og rørfittingen, dvs. vorten 2, anbringes pakninger 9 og 10. Derved får man en tett gjennomføring for ledningen 5 samtidig som denne klemmes fast på plass. The fitting 1 is suitably provided with a wart or thickening 2, so that the material here becomes sufficiently thick for the arrangement of a through hole 3. In the wall of the hole there is a groove 4 in which an electrically conductive wire 5 can be placed which is led over to a contact screw 6 which can also be arranged in a wart 7 on the pipe fitting. The hole 3 is sealed again with the help of a screw, as gaskets 9 and 10 are placed between the head of the screw 8 and the pipe fitting, i.e. the wart 2. This results in a tight passage for the wire 5 while this is clamped firmly in place.

Plastrøret 11 er hensiktsmessig stuk-ket inn i rørfittingen 1, som kan være forsynt med mothaker i de indre vegger. Samtidig med at plastledningen derved blir forsynt med en motstandstråd eller tinntråd, vil den også bli forsynt med jordledning som tjener samme formål som tidligere vannledninger av galvanisert jern eller kopper. The plastic pipe 11 is appropriately inserted into the pipe fitting 1, which can be provided with barbs in the inner walls. At the same time that the plastic line is thereby provided with a resistance wire or tin wire, it will also be provided with an earth wire that serves the same purpose as previous water lines made of galvanized iron or copper.
