Description
Technical field
The utility model is related to the test of water injection well in oil fields well head, for the associated component of hermetical testing valve, specifically
It is a kind of new type of water flooding test valve sealing joint.
Background technology
At present, injection well testing valve sealing joint in steel wire sealed packing be all to load from top to bottom, block up
Head bottom is shut, and plug inner disc root hole bottom escape has the screw thread of fastening packing with upper bit during due to processing, makes
Obtaining blowout-preventing choke plug needs that the packing at top can only be changed when changing packing, and bottom packing is due to plug pressure cap in test construction
Fastening causes packing rubber to expand, and is bonded on plug inner disc root hole screw thread, it is difficult to take out replacing, the packing of bottom is due to sealing hole
Grind bigger and bigger by steel wire, sealing function is lost substantially, and only top one packing in portion is extremely difficult to seal the effect of profit so that
Profit is taken in compartment and winch drum by steel wire, is caused steel wire corrosion, reduction of service life, is caused very big economic waste.
The content of the invention
The purpose of this utility model is aiming at above-mentioned deficiency present on prior art, a kind of new type of water flooding of design
Test valve sealing joint.
Above-mentioned purpose is realized by following technical proposals：
New type of water flooding tests valve sealing joint, including：Body, hoop, relief hole, seal head, sealing ring, release
Plug, regulation pressure cap, " O " grommet type seal, conduction hole, steel wire connect hole；Its new type of water flooding tests valve sealing joint body
Hollow structure is in the form of a column, the external screw thread that the internal thread that body upper part is provided with is provided with regulation pressure cap is engaged, and bottom is provided with clip
Head, the internal thread that hoop inner circumferential is provided with is engaged with the external screw thread that seal head is provided with, provided with one and body in the middle part of right-hand member
The relief hole of chamber insertion, relief hole is engaged with the release plug filled added with " O " grommet type seal.
Provided with sealing pipe screw thread outside the cylindrical frustum cone structure of its seal head, seal head, axis part is provided with diameter 5mm's
Provided with two-stage sealing ring up and down in mesopore, mesopore, bottom is provided with interior six side's counterbores.
It is in T-shape shape hollow design that it, which adjusts pressure cap, and regulation pressure cap axis part is provided with diameter slightly larger than steel wire diameter
Steel wire connects hole.
Its release plug is in step-like bar type structure, and release plug axis part is provided with one in drawing that " L " shape connects
Discharge orifice.
The beneficial effects of the utility model are：The air-tight manner of original pulling water nozzle is changed, airtight and watertight padding is changed easy
Fast, beneficial to clean manufacturing, and the service life of pulling steel wire is extended, with simple in construction, cost is low, security performance is high
It is also a kind of water injection well pulling water nozzle well head sealing joint that oil field is widely applied Deng technical characteristic.
