The invention relates to a fluid control valve, and provides a self-pressing fast-open micro faucet which is small in open and close torque, good in tightness, small in size, long in service life and capable of connecting water flow by using pressure inside a pipeline with light touch of external force. The self-pressing fast-open micro faucet comprises a faucet body, a fixed valve plate, a movable valve plug and a valve cover. The valve cover is arranged on the upper portion of the faucet body. The faucet body is provided with a water inlet channel and a water outlet channel, wherein the water inlet channel and the water outlet channel are used for allowing fluid media to pass through. A valve seat is arranged between the water inlet channel and the water outlet channel in the faucet body, the valve seat is provided with a valve opening, the valve plate is arranged on the valve opening of the valve seat in a mode of capable of being opened and closed, and the valve plate is provided with an air in-out hole. The movable valve plug is arranged above the fixed valve plate in the valve cover in a mode of capable of going up and down, a piston rod capable of releasing and pressing the fixed valve plate is fixedly arranged on the lower portion of the movable valve plug, and a magnetic locking device capable of enabling the movable valve plug to carrying out up-and-down lifting movements is arranged between the valve cover and the movable valve plug.
