Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described.
Seeing Fig. 1 and 2, one is with pressure changes valve system, including first flange the 1, second flange 2, leading screw 3 and blanking plug
4, wherein first flange the 1, second flange 2 is spaced in opposite directions and arranges and run through leading screw 3 between the installing hole of the two correspondence, and leading screw 3 is
The uniform six roots of sensation；All by threaded engagement, clamp nut 5 is installed on the leading screw of the first flange 1 both sides, i.e. can be by leading screw 3 and the
One flange 1 is fastened as a whole；Install on leading screw outside second flange 2 to install on the leading screw of pushnut 6, inner side and release nut
7.It is additionally provided with oil leak hole on first flange 1.
Blanking plug 4 includes axostylus axostyle 46 and the back of the body cap 41 being sleeved on successively on axostylus axostyle, packing element 42, first cone of centre
43, cartridge type slips 44 and the second cone 45, is constituted between wherein the conical surface of the first cone 43 and the second cone 45 is positioned opposite
Twin-stage inclined-plane, the both sides of cartridge type slips 44 recline with twin-stage inclined-plane respectively；Blanking plug 4 runs through the first flange 1 and the second flange 2
Interstitial hole, and the outer surface of the first end of blanking plug 4 second cone 45 can and the first flange 1 between constitute slipper seal join
Close, inner surface is connected by threaded engagement with axostylus axostyle 46, and the second end of the second cone 45 of blanking plug 4 is pacified by threaded engagement
Pressure cap 9, outer pressure cap 8 in dress, and fasten with the two sides of the second flange 2 respectively.
Operation principle is as follows:
When changing gate, first outer wellhead side gate is shut, lays down original tape ring flange, then by blanking plug 4 one end from
First flange 1 passes, and is put on by the second flange 2 from the other end, then by the first flange 1 with shaft collar flange is by leading screw 4
With clamp nut 5 tightened relative, the second flange 2 and blanking plug 4 are passed through interior pressure cap 9, outer pressure cap 8 tightened relative；Simultaneously advance
Nut 6 and release nut 7 are separately mounted to outside and the inner side of the second flange 2.
Blanking plug 4 process of press in: open outer side sleeve gate, interior side gate is also opened, and such well head homonymy gate is formed
One passage；Upper button releases nut 7 and pushnut 6, releases nut 7 and concedes the position of leading screw 4 and make the second flange 2 can
To move inwards, the effect of pushnut 6 is to force the second flange 2 to move by the screw thread effect of tightening, thus drives blanking plug 4 to lead to
Cross the second cone 45 to coordinate with the slipper seal of the first flange 1 and to gate medial movement；When being screwed to certain position, now block
Device 4 is delivered to inside interior side gate, and now blanking plug 4 is setting forms the stopper sealed, and outside is changed gate and would not be stressed impact.
Blanking plug 4 setting procedure: after blanking plug 4 moves into place, unscrews interior pressure cap 9, outer pressure cap 8, and force-multiplier tool is by adding
Power hole 47 makes axostylus axostyle 46 rotate forward, and now the second cone 45 moves to left under threaded function, thus compressing cartridge type slips 44, packing element successively
42 setting grapplings；Put in place when anchorage force is anticipated, open the relief hole on the first flange 1, without the most excessive phenomenon, show
Blanking plug 4 successfully blocks shaft collar, at this moment can be laid down by interior flood tide gate, be connected by the best gate, after connecting, and well
Mouth recovers beginning state.
Blanking plug 4 exits process: force-multiplier tool makes axostylus axostyle 46 invert by afterburning hole 47, and now the second cone 45 is at screw thread
Move to right under effect, so that cartridge type slips 44, packing element 42 unseal and release plugging device 4.Screw interior pressure cap 9, outer pressure cap 8, now
Blanking plug 4 makes it link together with the second flange 2 by interior pressure cap 9 and outer pressure cap 8, and twisting simultaneously is released nut 7 and advances
Nut 6 so that it is to the direction action released, releases loosening of nut 7 and just forces the second flange 2 to be displaced outwardly, so at screw thread
Effect under, the second flange 2 moves along leading screw 3 and just blanking plug 4 is pulled out.When blanking plug 4 arrives outer flange, respectively
Shut inside and outside gate, open the oil leak hole checking flange quality on outward flange.If gate is good, it is possible to lay down first
Flange, and together device is laid down, finally outer flange dish is connected.
This utility model is to utilize the slips of blanking plug and packing element to seal and be anchored on well head dedicated tunnel, and plugging fluid circulates
Road, is so that gate is isolated with high-pressure space, it is achieved dismounting operating gate.What blanking plug utilized is that on screw thread, unloading functions realizes glue
Cylinder and the action of slips, i.e. rotate forward and make packing element, cartridge type slips setting, and reversion makes the release deblocking of packing element, cartridge type slips.
It is only more than exemplary embodiments of the present utility model, is not used to limit this utility model；At this utility model
Protection domain in, those skilled in the art can carry out suitable adjustment to each control parameter completely according to actual needs, but
Identical with the principle of the various embodiments described above, within each falling within protection domain of the present utility model.
