Abstract
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 provided with a medium injection port. 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. The fire-fighting device can be connected to the medium injection port, and the fire-fighting medium can enter the box body, 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.
