The compression type glue barrel of the packing element 32 two ends steel ring protection of described setting mechanism 3, this is more ripe structure, it is simple to operation, reliable and stable.
The pressure reduction at balance packing element about 32 two ends when the design of described pressure relief mechanism 4 is to take out blanking plug, after pressure relief mechanism 4 is opened, blanking plug connects up and down, pressure balance；
As described in Figure 2, realize setting and unseal the special of use for this utility model and fetch and deliver instrument cross-sectional schematic, described instrument of fetching and delivering includes interior bar 20 and is set in the outer bar 10 outside interior bar 20, during use, mandrel 12 6 side of interior bar 20 6 side and this device that fetch and deliver instrument is docked, described outer bar 10 and the open butt joint of upper locknut 5.
The operation principle of Novel wellhead box cupling blocking valve that this utility model provide be described in detail below:
1, grappling
Being connected with special instrument of fetching and delivering by this device, after fetching and delivering instrument and being put at the box cupling of well head by this device, box cupling slips 21 by tube inner wall confined shrinkage, is strutted to be locked at box cupling by spring 23 and completes grappling in oil pipe.
2, set
When after this device grappling success, it is motionless that described box cupling slips 21 keeps fetching and delivering the interior bar 20 of instrument after flicking in box cupling, rotate the urceolus 10 of instrument of fetching and delivering, be compressed to set completely at the effect lower rubber cylinder 32 of leading screw at mandrel 1, the most directly go up extraction and send instrument to can be achieved with giving up.
3, pressure release
Needing to suppress in oil pipe during deblocking, piston 41 is cut off and is cut off 42 under pressure, and piston 41 is descending to be fallen to pumping out bottom valve 44, pumps out valve 44 and opens, the inside and outside connection of well.
4, deblocking
Enter to fetch and deliver instrument under pumping out after valve 44 is opened and dock completely with blocking valve, six sides of six sides and mandrel 1 that fetch and deliver the interior bar 20 of instrument are docked, outer bar 10 and the open butt joint of upper locknut 5, in now keeping, bar 20 is motionless, the outer bar 10 of counter-rotating, until packing element 32 unseals completely, epicone seat 22 returns to initial position, the interior bar 10 of instrument is sent in now upper extraction, i.e. can be taken off blocking valve；Do not have fully retracted slips to be in the lock state with the bigger strength epicone seat 22 that yet cannot bring forward proof when carrying on if, now continue to rotate urceolus 10, until slips unlocks completely.
Above-described embodiment, preferred embodiment the most of the present utility model, not for limiting practical range of the present utility model, therefore all equivalent variations done with content described in this utility model claim, within this utility model right all should be included in.
