After the gas in the reactor main body 1 is discharged, the acting force of the second spring 708 pushes the pressing plate 709 to move away from the surface of the bell 707, and the first spring 703 drives the sealing ball 705 to move downward. At this time, the alarm disappears, and the internal air pressure of the reactor main body 1 remains normal.
