Voir ® Bi-directional pressure relief valve

Scheme Description

High sealed products such as balanced battery boxes have bidirectional output pressure difference inside and outside, moisture resistance function, and meet the pressure difference performance of harsh environments. Ensure that under normal working conditions, the product will not fail to seal due to changes in internal and external environment (such as temperature and altitude changes) that exceed its tolerance due to pressure differences between the inside and outside.
A: Special battery PACK: Fill gas into the PACK without disassembly to achieve pressure retention, and enable pressure relief and explosion-proof function when thermal runaway occurs.

B: Military sealing device: without disassembly, the filling gas achieves the function of balancing internal and external pressure, while sealing dust and water. If necessary, manual pressing can also be performed to achieve pressure relief function.
