Patent attributes
A pressure relief device includes a mounting seat, a valve core, and a pressure relief member. The mounting seat is internally provided with a fluid channel, and the fluid channel is capable of communicating with an internal space of a component to be subject to pressure relief. The valve core is arranged to be aligned with the fluid channel in the mounting seat, and a pressure relief channel is formed between an outer edge of the valve core and an inner wall of the fluid channel of the mounting seat. The pressure relief member is sleeved on the outer edge of the valve core and is deformable and configured to open and close the pressure relief channel by means of its deformation. The pressure relief device of the present application utilizes the deformable property of the pressure relief member to achieve the effect of repeated use and multiple pressure reliefs of the pressure relief device.
