ABSTRACT:
An improved structure for a float valve assembly, utilizing a resisting disc which can be urged against or open the water outlet of the valve to stop or open the water flowing passage by the interrelated movement of a float, a float rod, a moving member, a cap and the resisting disc. The flowing direction of the water in the valve, i.e. the water pressure, can help push the resisting disc in covering up the outlet so the water flow can be stopped more easily and more effectively.
