Equipped with lower cone 20 on the central canal 1 of lower slips 13 side, lower cone 20 is slidably connected with lower slips 13, lower cone Equipped with traction body 21 on the central canal 1 of 20 sides, it is connected fixing between traction body 21 with lower cone 20 by holding screw.
Block 5 and left-handed control block 6 is controlled by hexagon socket cap head screw 28 and spring equipped with dextrorotation on traction body 21, interior The purpose of hexagonal cylindrical head screw 28 is to prevent dextrorotation from controlling block 5 and the rotation of left-handed control block 6.Left-handed control block 6 side It is movably installed with brake pad 22 by button spring 23 and brake pad back-up ring on traction body 21.
The left-handed control block 6 of the mechanical packer of this bidirectionally anchoring and dextrorotation control to be respectively arranged with screw thread on block 5, with Left hand thread 24, left-handed control block 6 and the left hand thread 24 on central canal 1 it is provided with on the central canal 1 of left-handed control block 6 correspondence Engaging each other, the central canal 1 of left hand thread 24 side is provided with right-handed thread 25, dextrorotation controls block 5 and the right side on central canal 1 Rotation screw thread 25 interval engages each other.It is provided with central canal shoulder 26 on central canal 1, lower sleeve 7 is provided with sleeve shoulder 27;In It is fitted and connected between heart pipe shoulder 26 and sleeve shoulder 27.
The mechanical packer of this bidirectionally anchoring by its function can be divided into sealing mechanism, set locking mechanism, anchor mechanism, Righting mechanism conciliates sealing mechanism.
Sealing mechanism: by back-up ring 9, bearings ring 10, nylon washer, seal receptacle 3, upper lead ring 11, upper packing element 17, packing element Spacer ring 19, lower rubber cylinder 18, packing element lining 8 are constituted.
Set locking mechanism: controlled block 5, left-handed control by box cupling 2, central canal 1, hexagon socket cap head screw 24, dextrorotation Block 6 and spring are constituted.
Anchor mechanism: by lower sleeve 7, upper cone 15, torque pin 14, upper slips 12 lower slips 13, slip sleeve 4, lower cone 20 are constituted.
Solve sealing mechanism: be made up of central canal 1, packing element lining 8, lower sleeve 7, left-handed control block 6.
Righting mechanism: be made up of traction body 21, brake pad 22 and button spring 23.
The work process of the mechanical packer of this bidirectionally anchoring is as follows:
Set:
Pressing and dextrorotation central canal 1 liang circle under appointment position under this packer, dextrorotation controls on block 5 off center pipe 1 Right-handed thread 25, box cupling 2 is closed downwardly against back-up ring 9, bypass.Pressing under Ji Xuing, seal receptacle 3 promotes whole sealing mechanism to transport downwards Dynamic.After packing element and slips are enclosed in lower pressure dextrorotation two, then upper lifting pipe post, so that lower slips 13 can more preferable anchor sleeve.Under continuation Pressure, extruding packing element seals annular space, then the dovetail groove on upper cone 15 promotes upper slips 12 to stretch out anchor sleeve.At upper slips 12 anchor During Ding, some power is delivered to lower slips 13 by slip sleeve 4, makes lower slips 13 stretch out along the dovetail groove of lower cone 20 Anchor sleeve.During whole pressure down, it is fixing that brake pad 22 assembly bottom this packer is threadeded with lower cone 20 Unshifting, brake pad 22 is fitted on casing wall so that it is can not move axially, but can spring open radially, it is provided that frictional resistance. Left-handed control block 6 and dextrorotation control block 5 and are waled by spring, and dextrorotation controls on block 5 off center pipe 1 after right-handed thread 25, left-handed Control block 6 be displaced to accordingly in the left hand thread 24 on central canal 1 and engage.Press under Ji Xuing, left-handed central canal 1, this Time, upper slips 12 has been anchored on casing wall, and downward power acts on glue by seal receptacle 3 and upper lead ring 11 and lower lead ring 16 On cylinder, make packing element outward expansion, be close to casing wall, thus realize setting.
Deblocking:
Stretched center pipe 1 and dextrorotation 4-8 circle, because of slips anchoring sleeve pipe, the dextrorotation of traction body 21 and inside controls block 5 and a left side Rotation control block 6 immovable, now left-handed control block 6 with under the cooperation of the left hand thread 24 on central canal 1, central canal 1 quilt Screw out.Making the left hand thread 24 of left-handed control block 6 off center pipe 1, above carry central canal 1, the shoulder 26 on central canal 1 carries upper During be close to the shoulder 27 of lower sleeve 7.Central canal 1 i.e. drives whole lower sleeve 7 each parts above upwards, and upper slips 12 solves Envelope.Meanwhile, the restriction cancellation on the left of packing element, packing element rubber self rebounds, it is achieved deblocking.During upwards, lower sleeve 7 leads to The boss of slip sleeve 4 is tangled by the step crossing its lower end, lower sleeve 7 thus drive slip sleeve 4 upwards, thus discharge lower slips 13 Deblocking.
The mechanical packer of this bidirectionally anchoring sets and unseals simple to operate, it is not necessary to any auxiliary equipment.And by In using bidirectionally anchoring structure so that it is be provided with higher two-way bearing capacity.This packer can be high pressure resistant, it is ensured that in operation During instrument mechanical performance keep constant.Structure is relatively easy and is easy to assemble.Brake pad 22 table of this packer bottom Face, through special handling, increases hardness, and wear-resisting, has the function of righting.This packer uses and controls block control, can be effectively Locking setting force, it is ensured that setting force continuous and effective.
