High-pressure gas cylinder valve for vehicle

A high-pressure gas cylinder valve for vehicle, comprising:

• a valve seat, wherein the valve seat is provided with a gas charging runner and a gas supplying runner,
• wherein a check valve is connected in series onto the gas charging runner, and a solenoid valve is connected in series onto the gas supplying runner in a gas flow direction,
• a portion of the gas supplying runner, located downstream of the solenoid valve, is jointly connected to a portion of the gas charging runner adjacent to a gas inlet end and supplies gas to outside through a gas inlet of the gas charging runner when the gas supplying runner supplies gas,
• the valve seat is further provided with a wire harness connector configured to be externally connected to the solenoid valve,
• the high-pressure gas cylinder valve for vehicle further comprises a first flow limiting valve, and the first flow limiting valve is connected in series onto the gas supplying runner, and is located downstream of the solenoid valve and upstream of an intersection of the gas supplying runner and the gas charging runner,
• wherein the valve seat is further provided with a discharging runner, a temperature pressure relief valve is connected in series onto the discharging runner, a discharging branch is led out from upstream of the temperature pressure relief valve on the discharging runner, and a manual discharging valve is connected in series onto the discharging branch, the discharging branch is jointly connected to a downstream position of the gas supplying runner at the first flow limiting valve, or the discharging branch is jointly connected to an upstream position of the gas charging runner located at the check valve, or the discharging branch is shorted to the temperature pressure relief valve, and an external wiring of the temperature pressure relief valve is led to the wire harness connector.
