Zusammenfassung:	A high-pressure gas cylinder valve for vehicle includes a valve seat. The valve seat is provided with a gas charging runner and a gas supplying runner. A check valve (401) is connected in series onto the gas charging runner, and the check valve and a solenoid valve (601) are connected in series sequentially onto the gas supplying runner in a gas flow direction. A portion of the gas supplying runner located downstream of the solenoid valve (601) 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 gas cylinder valve further includes a flow-blocking buffer structure, and the flow-blocking buffer structure is connected in series onto the gas supplying runner and is located downstream of the solenoid valve (601) and upstream of an intersection of the gas supplying runner and the gas charging runner. Through arrangement of the flow-blocking buffer structure, when the gas is charged into the gas cylinder through the gas charging runner, the high-pressure gas flowing into the gas supplying runner is blocked by the flow-blocking buffer structure. The solenoid valve (601) is prevented from being impacted by the high-pressure gas, the solenoid valve (601) is therefore prevented from being damaged, and the reliability and safety of the gas cylinder valve are improved.
