(28) airtight detector ontology (1) is opened, airtight detector ontology (1) will carry out harness ontology (2) with the air pressure of 15kpa
Air blowing 5s, then detector can carry out the pressure maintaining period of 15-16kpa within the time of 30s；
S3, baroceptor (31) can be detected the atmospheric pressure value of harness ontology (2) inside, then by the data transfer of detection
To data comparator (29), the atmospheric pressure value of detection is compared with alarming threshold value in data comparator (29), data compare
Alarming threshold value is fed back to central processing unit (28) by device (29) through feedback module (34), if being less than alarming threshold value, means that line
Atmospheric pressure value internal Shu Benti (2) is relatively low, while central processing unit (28) can open control switch (33) so that alarm
(30) it starts to work, thus can determine that the air-tightness of harness ontology (2)；
S4, when needing to be dismantled harness ontology (2), press pressure head (23), the buffering that pressure head (23) passes through fastening spring
Power squeezes the fixture block (21) being connected in card slot (22), so that fixture block (21) is squeezed out out of card slot (22),
Thus play the role of easy disassembly.
