Valve for water faucet and method for manufacturing the same
The present invention provides a valve for water faucet including an outlet pipe seat having a connecting seat via a first injection molding, an outlet pipe connector assembled to the connecting seat, and a hot water valve seat and a cold water valve seat integrally wrapping around the outlet pipe seat and the outlet pipe connector via a second injection molding. Each water valve seat includes a copper pipe sleeve secured to a water inlet pipe. The outlet pipe seat is formed with leak-proof rings on an outer surface thereof. Each water valve seat is formed with a water inlet pipe having a positioning post thereon and an annular wall set around the water inlet pipe. The copper pipe sleeve defines a positioning hole for receiving the positioning post when the copper pipe sleeve is positioned in the chamber between the annular wall and the water inlet pipe.
