Rotation driving it to move up and down.Generally, make spiral gland 16 with light-rod coaxial it is ensured that when it moves up and down, applying as far as possible
More equalize to the active force of shut-in well seal.
By screwing worm screw 15, drive worm gear 14 to rotate, and then drive the spiral gland being sleeved in worm gear to move up and down,
Compressing or to loosen shut-in well seal, as shown in figure 1, when driving spiral gland to move down, compressing shut-in well seal, so that shut-in well is sealed
Part locking polished rod, keeps shut-in well state.When needing to release shut-in well, reversely shake worm screw drives worm gear, and then drives spiral pressure
Put shifting, make shut-in well seal recover ortho states.Generally, shut-in well seal adopts the cushion rubber of oil resistant rubber, and cushion rubber is in polished rod
On be arranged side by side multigroup, strengthen active force when its sealing effectiveness and locking polished rod.
It is provided with spray-proof ball 17 between above-mentioned connect base 1 and described polished rod 2, described connect base 1 is provided with spray-proof ball
Accommodating chamber 18, this spray-proof ball accommodating chamber 18 cross section is in arc-shaped, and its upper end is provided with lead-in chamfered 19.The diameter of spray-proof ball is bigger
The through-hole diameter of polished rod is installed on connect base, its diameter is at least greater than the internal diameter of shut-in well seal.Furthermore it is possible in spray
All wearing layer can be applied it is ensured that connect base will not be worn on ball receiving luminal wall surface and lead-in chamfered.
Even if polished rod occurs the emergency case such as fracture, during fluid floats, spray-proof ball 17 can be along guiding surface
19 floatings, block spout, and spray-proof ball adopts nylon to support, and when blocking nozzle, form high pressure, sealing in connect base
Well, it is to avoid blowout, the crude oil loss because blowout causes and personnel's injury can effectively be prevented.
Above-mentioned master root cylinder 6 is threadeded with described master root gland 8, is provided with therebetween sealing ring.Above-mentioned tune mid-game 3
It is provided with and described connect base 1 between and adjust mid-game sealing gasket 20 it is ensured that sealing between structural member.
Several conducts are equipped with the excircle of above-mentioned master root gland, tune mid-game gland and secondary packing gland install
The blind hole 21 in hole, described blind hole 21 is uniformly arranged centered on described polished rod 2.Can be inserted blind using boosting-rod or special spanner
In the hole, is rotated, assembling time saving and energy saving it is ensured that the intensity of assembling product and convenience.
It is provided with adjustment gap between above-mentioned connect base 1 and described polished rod 2, when installing this well mouth sealing device, be more easy to
In assembling, need not just remain concentric with polished rod from the beginning of assembly connection base, even if there is certain deviation, in dress
Join when upper structure part and seal can gradually centering, assembly difficulty is low, and efficiency of construction is high, and will not damage polished rod.
Above-mentioned tune mid-game gland 4 is provided with for compressing the described boss 22 adjusting mid-game 3, this boss 22 surface and tune mid-game
Gland 4 contact portion, as locating surface, is finished, and remainder need not be finished, it therefore reduces difficulty of processing,
Locating surface using finishing contacts with adjusting mid-game gland, and assembly reliability improves.
By screwing worm screw 15, drive worm gear wheel, and then drive the spiral gland 16 being sleeved in worm gear to move up and down,
To compress or to loosen shut-in well seal, when needing shut-in well, to drive spiral gland to move down, compression shut-in well seal, so that shut-in well is sealed
Part locking polished rod, shut-in well is simple to operate, reliable and stable.
Major-minor packing in this sealing device does not need to stop well replacing, can at any time will using material feeding rifle when needing
Pellet packing adds, alternatively, it is also possible to according to actual conditions, not fill packing it is only necessary to adjust the gland that major and minor packing is located,
Reduce the space that corresponding packing is located, you can repack the fastening of packing, recover normal operating conditions.Therefore, it is possible to begin
Ensure that the reliability of sealing eventually, save manpower and working time, it is to avoid packing adds or with needing when changing to stop well, and overall
The drawbacks of remove sealing device, the addition of packing and replacing construction are reduced to almost nil.
Even if need to change respective seals (as major and minor packing_seal part), it is also the knot only needing to dismantle corresponding site
Component, you can directly change, without this sealing device of integral demounting, decreases time and the manpower that conventional replacing seal causes
Waste, reduce the working strength of workman.
The foregoing is only the preferred embodiment of the invention, not in order to limit the invention, all this
Within the spirit of innovation and creation and principle, any modification, equivalent substitution and improvement made etc., should be included in the invention
Protection domain within.
