Description

Anordning til å forhindre frysing av væskeledninger.
Oppfinnelsen går ut på en forbedring
av ved hjelp av varmeelementer å forhindre frysing av væskeledninger som ligger
fritt eller delvis fritt i terrenget.
På vedlagte tegning er fig. I lengde-snitt og fig. II tverrsnitt av væskelednin-gen.
Oppfinnelsen består i at det mellom et
ytre rør (1) og et indre væskeførende rør (2) er et luftsjikt som oppvarmes av et
varmeelement (3), som da skal holde en
høy nok temperatur til at væsken i det indre rør ikke fryser i den kolde årstid. Det
indre rør (2) er opplagret på klosser (4)
som da også er monteringsklosser for varmeelementet. Varmeelementet ligger i hele
rørets lengde og kan f. eks. være reguler-bart ved hjelp av et termoelement.

Claims (1)

  1. Anordning til ved hjelp av varmeelementer å forhindre frysing av væskeledninger som ligger på ikke frostfrie steder, med et ytre rør (1) og et indre væskef ør-ende rør (2) karakterisert ved et mellom-liggende luftsjikt som oppvarmes (3) i hele rørets lengde.
