VALVE, BATTERY, ELECTRIC DEVICE, AND MANUFACTURING METHOD FOR VALVE

Embodiments of the present application provide a valve, a battery, a power consumption device and an apparatus and a method for manufacturing the valve, and belong to the technical field of batteries. The valve includes a valve body and a closing member, the valve body being configured to be mounted on a box body, and the valve body being provided with a medium injection port configured to be connected to a fire-fighting device. The closing member is connected to the valve body and closes the medium injection port, and the closing member is configured to open the medium injection port when a pressure or a temperature inside the box body reaches a threshold, so as to relieve the pressure inside the box body and allow the fire-fighting device to inject a fire-fighting medium into the box body through the medium injection port. Thefire-fighting device can be connected to the medium injection port, and the fire-fighting medium provided by the fire-fighting device can enter the box body through the medium injection port, so as to cool the battery cell inside the box body and reduce the risk of large-area thermal diffusion of the battery cell inside the box body, thereby quickly and effectively controlling fire inside the box body and reducing economic losses caused by the fire.
