Multi-position controlled airway valve, refilling device and refilling system

A refilling device, comprising:

• a multi-position controlled airway valve;
• and
• a storage vessel, the multi-position controlled airway valve being fixedly connected to the storage vessel,
• wherein the multi-position controlled airway valve comprises:
• a venting control member;
• a valve body, provided with a fluid channel and a venting channel, wherein the venting control member is provided on the venting channel;
• a valve core assembly, mounted in the fluid channel, controlling the fluid channel to switch between a connected state and a sealed state, wherein the valve core assembly in a filling mode controls the fluid channel to be in the connected state and abuts against and opens the venting control member so as to keep the venting channel to be in a ventilated state.
