The working principle of the self-styled dry type quick coupling of the utility model locking type:
The operation handwheel on female connector is rotated when docking, and spiral of the cam on female connector along pin end outer surface is allowed to lead
It is slid into slot；
When rotation angle reaches 10 °, male and female connector front end combines and forms the confined space being isolated from the outside, then, public access
The spool of head and the valve seat of female connector are gradually shifted and are staggered；
When rotation angle reaches 120 °, to maximum opening, forming cross section is cricoid stream for spool and valve seat detent
Dynamic channel；
Then the only stopper circle on pin end is stirred, so that it is lockked female connector completely, prevents male and female connector from surprisingly disengaging,
So far, docking finishes.
When male and female connector needs to disengage, the only stopper circle on pin end is reversely stirred first, releases lockup state, so
Opposite direction rotates female connector afterwards, and process is contrary to the above；At this point, the respective spool of male and female connector, valve seat gradually reset closure,
Until completely cut off access；Continue to rotate, male and female connector just completes real mask work, avoids the leakage of medium.
In conclusion the self-styled dry type quick coupling of the utility model locking type is axially screwed in by female connector screws out pin end
