Description

Water inlet valve Technical Field The utility model relates to the field of bathroom, in particular to a water inlet valve. Background The water inlet valve of the toilet water tank is used as a core component for controlling the water level of the water tank, and the working pressure of the water tank drives the valve core on the water inlet valve main body to be opened and closed through the buoyancy change of the pontoon assembly, so that the water inlet amount of the water tank is controlled.
