Abstract
An inner water pipe assembly for faucet includes a copper shell with a longitudinal channel and a lateral channel. A valve seat is mounted in the longitudinal channel, and includes an inlet channel, an outlet channel, and a seat hole formed there through. A valve sleeve is fitted into the lateral channel, and has an inlet notch communicating with the inlet channel, a chamber inside the valve seat and an annular inlet passage formed between the valve sleeve and a valve. The valve is fitted into the pipe sleeve for water passage control. A valve chamber inside the valve communicates with the outlet channel of the valve seat and a water inlet formed through a periphery of the valve. The inner water pipe assembly provides a rational design reducing the copper material and cost in production, simplifying the manufacture, and resolving excessive heavy metal in drinking water.
