The charging valve includes: an outer valve body including a first inner cavity, the outer valve body is provided with a connection port in communication with the first inner cavity; an inner valve body movably installed in the first inner cavity, the inner valve body has a sealing position for closing the connection port and a charging position for opening the connection port, and the inner valve body is provided with a second inner cavity; and a valve core assembly, installed in the second inner cavity. The inner valve body of such a charging valve realizes the isolation of the valve core assembly from the connection port. A problem that air enters the air conditioning system in a vacuum state or that leakage appears in the valve core assembly is avoided.
