s5, after the pressurization detection is finished, releasing air in the closed space through a pressure release valve (10), reducing the air pressure of the closed space, and closing the pressure release valve (10) after each air pressure reduction;
s6, performing negative pressure detection, namely pumping air out of the closed space through a negative pressure valve (9) to reduce air pressure, and detecting the change of the air pressure in the closed space in real time through a pressure sensor (7);
s7, after the negative pressure detection is finished, releasing the air in the closed space through a pressure release valve (10), reducing the air pressure of the closed space, and closing the pressure release valve (10) after each air pressure reduction;
and S8, after detection is finished, the sealing cover (4) is moved upwards through the jacking mechanism (3) to separate the sealing cover (4) from the sealing base (5), the sealing base (5) is moved out from the lower end of the sealing cover (4) through the rotating mechanism, the rotating mechanism is fixed through the limiting piece, and after the rotating mechanism is fixed, the detection piece can be replaced and used for detection again.
