Movement, make sealing ring 28 by 23 pressure diameter of flange become larger and hole be tightly connected, after sealed connection by first medium hole 12 to
Medium is filled in product to be measured, fluid media (medium) is in connector followed by fluid media (medium) circulation portion 111, intercommunicating pore 22 and second
Medium holes 21, in the process since the diameter of intercommunicating pore 22 is much smaller than the diameter in first medium hole 12, fluid media (medium) exists
Flow of media portion inner product swaging forms pressure at pressure difference, to the end face of connecting rod 3, increases flange 23 to the power of sealing ring 28,
Increase flange 23 again to the pressure of sealing ring 28, so that the diameter of sealing ring 28 is further swollen, it is more firm to seal；Work terminates
Afterwards, handle 4 is turned down into go back to original position, reduces 28 pressure of sealing ring, diameter reduces, and smoothly extracts connector completion detection.
During the work time, when hole is smaller, by locknut 5 and circumferential 1 direction of cylinder body adjustment is adjusted, increases handle 4 and supports
The distance between end 41 and adjusting 6 end face of ring, reduce pressure suffered by sealing ring 28；When hole is larger, by locknut 5 and ring is adjusted
The distance between it is adjusted to 4 direction of handle, reduce support end 41 and adjust 6 end face of ring, increase the suffered pressure of sealing.
After completing sealing, equipment is filled with using medium and is filled with fluid into object to be detected from the first medium hole of connector
Medium, to detect the air-tightness of object to be detected.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
