Abstract:
1. A mixing valve assembly comprising a mixing valve including a valve body having: a first rotating element connected to a valve stem for turning on and off said mixing valve, and for adjusting outlet water temperature of said mixing valve; and a first mark on said first rotating element; and a second rotating element being an integral part of a water-tight enclosure of said mixing valve, maintaining a water-tight seal of said water-tight enclosure while being rotated, and forming said water-tight enclosure that envelopes said valve body of said mixing valve, covers a hole in a shower wall thereto said valve body penetrates, and prevents water leakage to a hidden area behind said shower wall; and a second mark on said second rotating element; wherein: a relative movement between said first and second marks occurs when said first rotating element is rotated; and said mixing valve is capable of presetting said outlet water temperature to a desired water temperature by, firstly, rotating said first rotating element to a stop position corresponding to said desired water temperature, and secondly, rotating said second rotating element to a stop position where said second mark meets said first mark; and said mixing valve is capable of retrieving said desired water temperature after said mixing valve being pre-set to said desired water temperature, in which, said first rotating element is rotated to a stop position where said first mark meets said second mark.
