Abstract: An air pressure relief valve providing relief against both gradual and sudden changes in pressure is disposed on an opening of an assembly of parts. The valve includes a plurality of blades, the blades are circumferentially distributed and abut each other. Each blade includes a nozzle end, the nozzle ends abut each other, and a part of the nozzle end on each blade allows deformation by internal air pressure to form an air hole, wherein air can enter or exit the functional assembly through the air hole. The thickness of the blade gradually decreases in direction from a thick base end to the thinner-section air nozzle end.
