ABSTRACT:
A faucet includes a faucet body, a sleeve, a control valve, and a mounting seat. The control valve includes a control shaft, a stop gasket, a retaining member, a leakproof gasket, a sealing gasket, a first leakproof cap, a second leakproof cap, a control knob, and a restoring member. Thus, the sealing gasket, the leakproof gasket, the first leakproof cap and the second leakproof cap of the control valve are tightly and closely located between the control shaft and the through hole of the faucet body to seal the through hole so as to prevent the water from leaking from the through hole and to stabilize the water pressure in the faucet body.
