摘要： The present invention relates to a valve core. The valve core comprises a valve housing, a valve handle, a rotor, a driving plate, a movable valve sheet and a fixed valve sheet. The driving plate is disposed on the bottom of the rotor, the movable valve sheet disposed inside the valve housing and below the driving plate; the fixed valve sheet disposed inside the valve housing and located at the bottom of the valve housing. The driving plate has a limiting portion; the valve housing has two inner blocks. Only when the limiting portion is aligned with the limiting recess, the movable valve sheet is capable of sliding with the driving plate in a direction of closing inlet water, when the limiting portion is exposed to a periphery of the rotor, the limiting portion inserts into the limiting recess; and when the driving plate rotates in a state where the limiting portion and the limiting recess are misaligned, the limiting portion is blocked by the inner blocks, so as to stop the movable valve sheet from sliding with the driving plate in a direction of closing inlet water. The present invention also relates to a pull-out faucet.
