[0002] In the hydrogen supply system of fuel cell electric vehicles, the current common safety measure is to add a safety valve on the hydrogen supply pipeline, that is, when the safety valve exceeds a certain pressure, hydrogen will be released to ensure the safety and normality of downstream pipelines, joints and sensors However, when the safety valve fails to work according to the design conditions and requirements, the downstream pipelines and joints face the risk of being damaged, and at the same time, it is very easy to explode or even explode and burn in a short time, thus causing serious harm to the occupants of the vehicle. Safety hazard and huge loss of property

Embodiment Construction
[0030] The following descriptions of various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention can be implemented.
[0031] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, this embodiment discloses a valve device for manually discharging hydrogen. The valve device for manually discharging hydrogen includes a connection housing 1, a valve base 2 and a valve core 3. The outer surface of the connection housing 1 has a first interconnected The connection joint 11, the second connection joint 12 and the installation valve joint 13, the valve base 2 is connected to the installation valve joint 13 and communicated with the connection housing 1, the valve core 3 is arranged in the valve base 2 and is used to open or close the valve Base 2.
[0032] The first connection joint 11 and the second connection joint 12 can be connected to the hydrogen supply pipeline, so that the connection housing 1 communica...

The invention discloses a manual hydrogen discharge valve device, a hydrogen supply system and a fuel cell electric vehicle. The manual hydrogen discharge valve device comprises a connecting shell, a valve base and a valve core. The outer surface of the connecting shell is provided with a first connecting joint, a second connecting joint and a mounting valve joint, all of which are in communication with one another, the valve base is connected to the mounting valve joint and communicates with the connecting shell, and the valve core is arranged in the valve base and used for opening or closing the valve base. The hydrogen supply system comprises the manual hydrogen discharge valve device. The fuel cell electric vehicle comprises the hydrogen supply system. The valve base can be opened or closed by manually controlling the valve core, and therefore hydrogen in a hydrogen supply pipeline is manually discharged in a one-way manner; and when a safety valve in the hydrogen supply pipeline cannot work normally, the hydrogen in the hydrogen supply pipeline can be manually discharged in a one-way manner, and therefore the potential safety hazard of explosion caused by sharp increase of pressure within a short time is effectively avoided, and the safety is greatly improved.
