LEAKAGE PREVENTION STRUCTURE FOR CONNECTION PART OF CORRUGATED PIPE

摘要

The present invention relates to a leak-proof connection structure of a spiral wave tube for fluid transfer having protrusions and recesses formed on an outer circumferential surface thereof. It was made;Double spiral wave tube in which the protruding ring portion 1a and the concave portion 1b are spirally formed on the outer circumferential surface thereof.;(1) In the installation of unvulcanized rubber at the connection portion where both ends of (1) are connected, and fastening with a pair of semi-circular connectors (4) (4),;A non-vulcanized rubber adhesive piece 2 is covered and bonded on the protruding ring connection gap G 'formed at the cut portion of the connected spiral wave tube 1, 1, and is not vulcanized along the concave connection gap G. The rubber belt 3 is wound around one turn to be crimped with the connecting ports 4 and 4 to prevent leakage.
