The utility model discloses a battery box fire extinguishing device and vehicle battery system and fork truck, including fire extinguishing host computer, first control valve and second control valve, and fire extinguishing host computer is equipped with fire extinguishing agent output port, first control valve is equipped with first import, always with first import intercommunication's first export, the second export of switchable on-off, second control valve is equipped with second import, the third export of switchable on-off, first control valve is equipped as one time, and fire extinguishing agent output port intercommunication first control valve's first import, and first control valve's first export intercommunication second control valve's first import, when first control valve is equipped as multiple, and multiple first control valve series connection forms multistage flow path, wherein, first import intercommunication fire extinguishing agent output port of first stage, and first export intercommunication second import of last stage, and through first export of former stage intercommunication first import of latter stage between adjacent stage. When the number of battery box changes, only need to adjust the number of first control valve accordingly, namely can complete system expansion or simplification quickly.

The utility model belongs to the technical field of flow batteries, and particularly relates to a gas circulation system of a flow battery. The flow battery gas circulation system comprises a positive electrode liquid storage tank, a negative electrode liquid storage tank, a gas inlet pipeline, a gas exhaust pipeline, a gas pressure balance pipeline and a gas transfer device, the upstream end of the air inlet pipeline is positioned above the liquid level of the positive electrode liquid storage tank; the downstream end of the gas inlet pipeline is communicated with the inlet of the gas transfer device; the outlet of the gas transfer device is communicated with the upstream end of the exhaust pipeline; the downstream end of the exhaust pipeline is located below the liquid level of the negative electrode liquid storage tank. And two ends of the air pressure balance pipeline are respectively communicated to positions above the liquid levels of the positive electrode liquid storage tank and the negative electrode liquid storage tank. The gas transfer and reactive gas absorption process is realized, volatile gas and toxic waste gas can be quickly and effectively absorbed, the pressure balance of the positive and negative electrode liquid storage tanks is maintained, the change of active components of the electrolyte during operation is avoided, and the safety and high efficiency of long-time operation of the flow battery are maintained.
