CHARGING VALVE, AIR CONDITIONING SYSTEM AND ELECTRIC VEHICLE

WIPO Patent Application WO/2020/015350

A1

Disclosed are a charging valve, an air conditioning system and an electric vehicle. The charging valve comprises: an outer valve body (10) comprising a first inner cavity (11), with the outer valve body (10) being provided with a connection port (12) in communication with the first inner cavity (11); an inner valve body (20) movably mounted in the first inner cavity (11), with the inner valve body having a sealing position for closing the connection port (12) and a charging position for opening the connection port (12), and the inner valve body (20) being provided with a second inner cavity (21); and a valve core assembly (30), mounted in the second inner cavity (21). The inner valve body of such a charging valve can realize the isolation of a valve core assembly from a connection port; when an air conditioning system is vacuumized, an unused charging valve does not cause incomplete vacuumization due to an insufficient spring force; and at the same time, the problem that air enters an air conditioning system in a vacuum state or that a leakage appears in a valve core assembly can be avoided.
