Anti-explosion pressure release valve and battery module

The utility model provides an anti-explosion pressure relief valve, and relates to the field of pressure relief equipment. A connecting main body is provided with a gas flow channel for gas to flow; the gland is fixed at the exposed end of the connecting main body, and a clearance channel for gas to flow out is arranged between the connecting main body and the gland; the movable assembly is installed in the space between the connecting body and the gland. In the sealed jacking state, the elastic piece exerts elastic force on the piston and abuts against the connecting body in a sealed mode, at the moment, airflow can pass through the breathable film and the inlet and outlet channel to conduct internal and external exchange, and internal and external air pressure balance is kept. When the internal pressure rises rapidly, the air pressure ejects the movable assembly open, the elastic piece is compressed, the airflow is discharged through the receding channel, rapid pressure relief can be achieved, and internal
