Watts 41；
Under the rotation driving effect of the actuating sleeve 22, the packing element 31 can first radial dilatation and external pipe inner wall phase
Contact, the slips 41 is then moved radially to be in contact with external pipe inner wall, in the present embodiment, increases specifically, slowing down
Away from and driving mechanism 2 further include action axis 23, this action axis 23 around the driving pedestal 11, tubular cavity 12 arrangement, and
The seal assembly 3, anchoring and interlock assembly 4 are drivingly connected by this action axis 23 and the actuating sleeve 22, seal assembly 3,
Anchoring and interlock assembly 4 are axially sequentially arranged around the action axis 23 and along tubular cavity 12, and seal assembly 3 has around row
The packing element 31 that moving axis 23 is arranged, anchoring and interlock assembly 4 have the slips 41 arranged around action axis 23；Actuating sleeve 22 is neighbouring to be subtracted
The side of fast mechanism and the driving pedestal 11 have radial clearance, and action axis 23 has radially projecting action portion in the side
231, the radial outer wall in this action portion 231 is mutually drivingly connected with 22 inner wall of actuating sleeve, the portion of action in the present embodiment 231 with
Between actuating sleeve 22 by the way of threaded engagement, make action axis 23 can the drive described in the rotation driving effect lower edge of actuating sleeve 22
Moving base 11, the axial movement of 12 outer wall of tubular cavity；Packing element 31 and slips 41 can diameters under the driving effect of the action axis 23
It is in contact to expanding and moving radially with external pipe inner wall；
Anchoring and interlock assembly 4 further include arranging positioned at 41 axial sides of slips and around the action axis 23
Cone seat 42 and the second sheath 43, seal assembly 3 also have the first sheath 32 arranged around the action axis 23, first shield
For set 32 adjacent to the action portion 231, first sheath 32 and the second sheath 43 are located at the axial sides of the packing element 31
(the second sheath 43 is between packing element 31 and slips 41)；Packing element 31 and slips 41 have taper in respective axial sides respectively
Face, shown in Fig. 4,5,7,8, packing element 31 is the shape that ecto-entad (radial direction) gradually expands, and slips 41 is by extroversion
The shape that interior (radial direction) gradually tapers up, corresponding, the first sheath 32, the second sheath 43 side corresponding with packing element 31
Portion has shape compatible with packing element 31, and the second sheath 43, cone seat 42 have and slips in side corresponding with slips 41
41 compatible shapes, the second sheath 43 have shape compatible with packing element 31 and slips 41 respectively in its two sides；Using upper
It states under the driving effect for being arranged and the second sheath 43 and cone seat 42 being made to be expert at moving axis 23 (action axis 23 moves axially) and squeezes institute
Stating packing element 31 and slips 41 makes its (successively) radial dilatation, movement respectively and is in contact with external pipe inner wall.
Specifically, action axis 23 and actuating sleeve 22 have axial gap in the side towards deceleration mechanism, actuating sleeve 22 revolves
Turn to drive action axis 23 towards the direction movement close to deceleration mechanism (direction far from the first sheath 32)；In this embodiment, it bores
Seat 42 has the extension 421 extended towards second sheath 43 and with action 23 face contact of axis, the extension 421
With position first limiting groove 422 corresponding with the slips 41, there is limit lock ring in first limiting groove 422
44,44 preferred elastomeric material of lock ring is limited, is contracted in the first limiting groove 422；When limit lock ring 44 is recessed positioned at the first limit
When in slot 422, also with 43 face contact of the second sheath, i.e. the effect of the limit lock ring 44 is the second sheath of limitation 43 and cone seat 42
It is close to each other；When axis 23 of taking action is mobile, the second sheath 43, packing element 31, slips 41, cone seat 42 is driven to move together, due to glue
Cylinder 31 is extruded generation flexible deformation first, and packing element 31 is in contact prior to slips 41 with external pipe inner wall；Later, lock ring is limited
44 are elastically deformed and detached from the first limiting groove 422 under constantly squeezing action, between cone seat 42 and the second sheath 43
Generation moves towards (i.e. distance reduces therebetween), and slips 41 is radially outward moved along the inclined-plane of the second sheath 43, cone seat 42
It is dynamic, it is in contact with external pipe inner wall, intelligence keyholed back plate pipeline packer starts to block operation；The deblocking of intelligence keyholed back plate pipeline packer is completed in operation
When, motor 21 inverts, and moves backward the driving action axis 23 of actuating sleeve 22, slips 41 is withdrawn, and limit lock ring 44 returns to the first limit
In the groove 422 of position, the second sheath 43 is moved together by the restriction effect of limit lock ring 44 by the drive of cone seat 42 at this time, packing element 31
The squeezing action being subject to is gradually reduced, and 31 shape of packing element is restored, and deblocking is completed；With the intelligence keyholed back plate pipeline packer being as above arranged,
When slips 41 moves radially, the also continuous extrusion external pipe side wall of packing element 31, after slips 41 reaches anchoring dynamics, intelligence keyholed back plate
Plugging effect possessed by pipeline packer is best；During closure operation terminates deblocking, the recycling of slips 41 is relatively smooth.
