WATER SUPPLY PIPE CORROSION PROOF KIT, CORROSION PROOF SLEEVE AND INSTALLING JIG FOR CORROSION PROOF SLEEVE

摘要

To provide a water supply pipe corrosion proof kit capable of restricting erroneous fitting to the water supply pipe, a corrosion proof sleeve and installing jig for the corrosion proof sleeve.SOLUTION: This invention comprises a cylindrical corrosion proof sleeve 2 installed at a hole formed to pass through a water supply pipe and an installing jig 3 used for inserting the aforesaid corrosion proof sleeve 2 into the aforesaid hole. The aforesaid corrosion proof sleeve 2 is provided with an engaging part at an inner peripheral part at its extremity end in an inserting direction into the aforesaid hole. An outer peripheral part of the aforesaid inserting shaft part 32 is provided with an engaged part to which the aforesaid engaging part of the inserted corrosion proof sleeve 2 is engaged. The aforesaid engaging part has an extremity end surface 231 at an extremity end in the aforesaid inserting direction. The aforesaid engaged part abuts against an extremity end surface 231 of the aforesaid engaging part when the aforesaid inserting shaft part 32 is inserted from the extremity end side in the aforesaid inserting direction in respect to the aforesaid corrosion proof sleeve 2, whereby it has a regulation surface 331 for restricting the insertion subsequent to this abutment.SELECTED DRAWING: Figure 5
