Description
Technical Field
A temperature control eccentric joint supporting water return and circulation functions has the functions of providing a temperature control circulation channel, reverse isolation and negative pressure isolation for cold water retained in a hot water pipeline while realizing the connection of a faucet and a pipeline in a wall.
Background
With the continuous maturity of the circulation technology, people's consciousness on saving the abandoned water is improved. Usually, a special water return pipe is installed during decoration to provide a circulation passage. However, in most of the finished environments, the special pipeline cannot be constructed, so that the environment is difficult to recycle, and particularly, the wall-mounted faucet cannot be realized. The invention aims to change an eccentric joint for connecting a faucet and a pipeline in a wall into an eccentric joint with a water return channel.
