Choke top margin be and the consistent circular conical surface of slope.103 one end of connecting plate of 62 upper end of column and rubber sleeve 102 contradict,
Connecting plate 103 is for driving rubber sleeve 102 to move down.For rubber sleeve 102 during moving down, choke is along inclined-plane
62 peripheral sealing of column is achieved the effect that be sealed channel 61 toward contract.
Working principle: when installing to long-radius nozzle 3, long-radius nozzle 3 being put into measurement pipe 1, by long-radius nozzle 3
On annular groove 5 abutted with the stop collar 4 on 1 inner wall of measurement pipe, then by rotation turning set 641, work of the turning set 641 in screw thread
Under, the spacing between column 62 and guiding surface 642 is gradually gradually become smaller, and column 62 supports under the action of guiding surface 642
Tight long-radius nozzle 3, to achieve the effect that fixed or unclamp long-radius nozzle 3；It is increasingly towards inside measurement pipe 1 and moves in column 62
In dynamic process, connecting plate 103 drive rubber sleeve 102 moving down, gum cover down move during, choke along
First inclined-plane is toward contract, and 62 peripheral sealing of column achievees the effect that be sealed opening 101 and channel 61.
When dismantling to long-radius nozzle 3, then turning set 641, effect of the turning set 641 in screw thread are rotated backward
Under, the spacing between column 62 and guiding surface 642 gradually becomes larger, then the effect that column 62 pushes against long-radius nozzle 3 is cancelled,
Long-radius nozzle 3 can be dismantled.
