BENDING PIPE PART PROTECTIVE COVER OF WATER/HEATED-WATER SUPPLY PIPE AND PIPE STRUCTURE OF ONE WATER/HEATED-WATER SUPPLY PIPE HAVING BENDING PART

摘要

PROBLEM TO BE SOLVED: To prevent a protective cover from slipping out in a bending part of a pipe, by lengthening the length of one pipe by bending the middle of the pipe.;SOLUTION: This bending pipe part protective cover K₁ of a water/heated-water supply pipe P is provided for storing and protecting the bending part P₁ of bending the middle of one flexible synthetic resin water/heated-water supply pipe P at substantially 90°. In the vicinity of two connection ports 17 in a base V₁ for constituting the protective cover K₁ and on the outside of a bending pipe passage A₁, a regulating wall W₂ is formed for regulating the movement to the outside so that a bending part forming angle formed of two straight line parts P₂ of the bent water/heated-water supply pipe P becomes large by extending by the thermal expansion of the water/heated-water supply pipe P or abutting by restoring force by bending, and on the outside of the bending pipe passage A₁ in the protective cover K₁, an entrance allowing space D₂ is formed for allowing an entrance of the bending part P₁ of the water/heated-water supply pipe P extended by the thermal expansion.;COPYRIGHT: (C)2012,JPO&INPIT
