The second expanded rubber sealing ring being set in hollow stem, the second expanded rubber sealing ring top are provided on third gasket
It is provided with the second gasket being set in hollow stem, second gasket upper end is provided with the first expansion being set in hollow stem
Rubber seal is provided with the first gasket being set in hollow stem, the hollow stem on the first expanded rubber sealing ring
Top is threaded with pre-load nut.
Preferably, medium position wear ring on the tailstock, the wear-resisting ring set is in hollow stem.
Preferably, end face rubber buffer circle is arranged on the preceding sealing ring.
The utility model proposes one kind can be used for helium inspection rapid expanding connector, beneficial effect is: expanded rubber sealing
Circle is shared well to playing on aluminum component pipeline or easily-deformable material internal expansion stress, while increasing contact area, and list is avoided
Only direction stress leads to that pipeline swells and the frictional force not enough failure that falls off when size is bad or detection, expanded rubber sealing ring,
Sealing number is improved, the erroneous judgement reduced in production process is possible, using end face rubber buffer circle circle, prevents connector straight in detection process
Connect with the direct contact wear in pipeline end face, prevent edge face sealing member to be scratched, fail.
