Multifunctional softening valves are widely used to switch water flow channels and realize functions such as water production, backwashing, salt absorption / slow washing, water replenishment to a salt tank, and forward washing.

[0003] In order to realize the above-mentioned multiple functions in one valve body, various cavities or flow guide holes need to be arranged on the valve body and the valve disc, and the water flow path is changed to realize the above-mentioned various functions. In this way, the water inflow and outflow under the normal water production function are limited by various structures on the valve body and the valve disc.
