Description

Soft water valve Technical Field The invention relates to the technical field of water treatment equipment, in particular to a soft water valve. Background Along with the improvement of the living standard of people, the requirements of residents on the quality of living water are improved. The domestic water contains a large amount of calcium and magnesium ions, and especially in northern areas, the domestic water causes equipment such as kettles and the like to easily form scale after being boiled, and clothes are easy to yellow. Water softener, such as water softener, water purifying equipment integrating soft water function, etc., can effectively remove calcium and magnesium ions in domestic water and improve water hardness.
