Beschreibung
Zusammenfassung:	The utility model belongs to the technical field of tire inflation and deflation, and particularly relates to a pneumatic tire deflation valve rubber diaphragm which is in a circular disc shape and comprises an edge part, an edge sealing part, a deformation part, a central sealing part and a central hole part, the edge part and the edge sealing part of the rubber diaphragm are located on the same plane, the center sealing part and the center hole part are located on the other plane, and the connecting part between the two planes is a deformation part. The stretching direction of the rubber diaphragm in the using process is from the plane where the center sealing part and the center hole part are located to the plane where the edge part and the edge sealing part are located. According to the rubber diaphragm, the stretching amount in the using process is reduced, the diaphragm strength is improved, the rubber diaphragm is not prone to fatigue damage, and the service life of the rubber diaphragm is prolonged. 本
