A water tap, which comprises a housing having an outer cap mounted on its water supply outlet to secure therein a water intake cap, a control shaft, a control bolt and a ring-shaped element. The control shaft comprises an upper circular groove with a stop cock mounted thereon, and a lower circular groove with a ring-shaped water seal mounted thereon. When the control shaft is pushed upward, water flow is permitted to pass through water inlet holes on the water intake cap for discharging out of the outer cap. When pressure force is released from the control shaft, water flow is accumulated in the inner space of the water intake cap and the inner space of the control shaft permitting water pressure to force the control shaft to move downward so as to block up water supply. The control bolt can be turned to move up and down inside the control shaft so as to control the flow rate through the throughholes around the periphery of the control shaft.
