The utility model discloses an explosion-proof abnormal-pressure-relieving device for a vulcanizing machine bladder during vacuumizing, and solves the technical problem that the bladder is damaged when the vulcanizing machine bladder is pressed under the non-vulcanization working condition. The explosion-proof abnormal-pressure-relieving device for the vulcanizing machine bladder during vacuumizing comprises the vulcanizing machine bladder body (1), wherein the vulcanizing machine bladder (1) is respectively connected with a superheated water input pipe (2), a superheated water output pipe (3) and a vacuumizing pipe (6); a superheated water input valve (4) is arranged on the superheated water input pipe (2); a superheated water output valve (5) is arranged on the superheated water output pipe (3); a vacuumizing control valve (7) is arranged on the vacuumizing pipe (6); the vacuumizing pipe (6) is communicated with a vacuumizing main pipeline (8) through the vacuumizing control valve (7); a pressure relieving pipe (9) is communicated with the vacuumizing main pipeline (8); a check valve (11) is connected with the outer end of the pressure relieving pipe (9). The explosion-proof abnormal-pressure-relieving device is capable of quickly taking effects and actively removing the dangerous pressure of the pipeline when the pressure of the vacuumizing pipeline is abnormal.
