Abstract: A balance valve, a battery, and a power consumption apparatus are provided in the embodiments of the present application. The balance valve includes a body, a breathable membrane and a gas barrier structure, where the body is provided with a ventilation channel; the breathable membrane is arranged at one end of the ventilation channel; and, the gas barrier structure is arranged at the other end of the ventilation channel, and the gas barrier structure is configured to open the ventilation channel when the gas pressures inside and outside the gas barrier structure are unbalanced, so as to achieve the gas pressure balance between the inside and outside of the gas barrier structure. The balance valve is applicable to a battery, which could achieve a balance of gas pressures inside and outside the battery when there is a pressure difference between the inside and outside of the battery.
