The invention discloses a passenger emergency alarm valve, and relates to the technical field of vehicle braking. The air release valve comprises a valve body, and an air release valve seat, a first reset spring, a reset spring baffle, a piston and an air release valve piston rod which are arranged in the inner cavity of the valve body, wherein a cavity A is formed between the air release valve seat and the reset spring baffle, and a first connector connected with a brake pipe is arranged on the side wall of the valve body. An upper cover is arranged at the upper end of the valve body, a cavity B is formed between the piston and the reset spring baffle, a cavity C is formed between the piston and the upper cover, and the upper cover is provided with a second connector connected with a carriage pilot valve. An inflation channel is arranged in the air release valve piston rod, and an inflation hole, a shrinkage plug I and a shrinkage plug II are arranged on the air release valve piston rod. By means of the technical scheme, the train can be braked emergently, the performance is reliable, the operation is simple, and safe operation of the train is facilitated; and after the train is emergently braked, certain air pressure can be reserved in the brake pipe, next release after the train is emergently braked is facilitated, and good application prospects are achieved.
