Description
Technical field
The utility model relates to pipeline in workover treatment and connects key equipment used, specifically a kind of anti-theft oil plug.
Background technology
Plug is parts conventional in oil field operation, is that a kind of hoop through Production tree for pumping well of being everlasting, restriction choke or oil transportation oil pipe end are used as plug.Its structure be external surface with tubing round thread, rear end mill becomes the solid cylinder of six sides.Structure is simple, is convenient to installation and removal.But to the oil well be positioned near village, occur repeatedly from the plug stolen event of production tree side, supervision difficulty.Not only have impact on the normal production in oil field, also pollute the environment of wellsite.
Summary of the invention
The purpose of this utility model is the defect overcoming the existence of above-mentioned prior art, provides a kind of anti-theft oil plug.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises plug and plug switching mechanism two parts, it is characterized in that: plug is set to cylindrical, central part is provided with a cylinder shape groove, is provided with male thread in the periphery of cylinder shape groove, on the resistance oil nozzle sleeve that plug is arranged on oil well or the end of petroleum pipeline; Plug switching mechanism comprises torsion bar, housing, handle, gland and slip insert, and be enclosed in the housing being provided with three opennings in the middle part of torsion bar to bottom, torsion bar bottom is provided with three angles 120
0deep-slotted chip breaker, the inner cambered surface of deep-slotted chip breaker and slip insert matches, the card tooth of the outer end of slip insert and the openning of housing match, housing is inserted in plug, the card tooth of slip insert is engaged with the groove of plug by the openning of housing, by the rotatable handle torsion bar set by torsion bar top, Ka Ya is engaged with the groove of plug, by rotating torsion bar handling plug.
Described torsion bar is set to cylindrical, and upper diameter is less than lower diameter, and top radial direction is provided with handle hole, and bottom is provided with band three Baltimore grooves, angle 120 between three Baltimore grooves
0.
The utility model has the advantages that easy to use, safe and reliable.The end of plug is inner circle structure, after installation, concordant with restriction choke, the first-class place of clip, without any catching part, uses general tool to dismantle, thus plays anti-theft function.Only have and insert the endoporus of Anti-theft wrench to plug rear end, rotary handle, slip insert protrudes, and stings the inner headed face of tight plug, could realize the loading, unloading of screws valve for preventing illagel application.And slip insert have employed carburizing quenching process, guarantee its intensity and case hardness.

Detailed description of the invention
For disclosing the technical solution of the utility model further, elaborated by embodiment below in conjunction with Figure of description:
Anti-theft oil plug, comprise plug and plug switching mechanism two parts, it is characterized in that: plug 2 is set to cylindrical, central part is provided with a cylinder shape groove, male thread is provided with, on the resistance oil nozzle sleeve 3 that plug is arranged on oil well or the end of petroleum pipeline in the periphery of cylinder shape groove; Plug switching mechanism comprises torsion bar 4, housing 6, handle 1, gland 5 and slip insert 7, be enclosed in bottom in the middle part of torsion bar in the housing being provided with three opennings, torsion bar bottom is provided with the deep-slotted chip breaker of three angles 120 degree, the inner cambered surface of deep-slotted chip breaker and slip insert matches, the card tooth of the outer end of slip insert and the openning of housing match, housing is inserted in plug, the card tooth of slip insert is engaged with the groove of plug by the openning of housing, by the rotatable handle torsion bar set by torsion bar top, card tooth is engaged with the groove of plug, by rotating torsion bar handling plug.
In order to further describe the structural principle of this device, accompanying drawing further illustrates it to specifications below.
Accompanying drawing 1 is scheme of installation of the present utility model.The male thread of plug 2 and the inner oil tube threaded engagement of production tree resistance oil nozzle sleeve 3 are installed.The outer face of the plug 2 after installing is almost concordant with resistance oil nozzle sleeve end face, without any catching part.Have only and can unload in the groove of plug switching mechanism insertion plug 2, handling of in addition having nothing for it, thus play antitheft effect.
Accompanying drawing 2 is the scheme of installation of plug and torsion bar.One end mill of torsion bar 4 becomes three angles 120
0deep-slotted chip breaker, the other end is provided with radial direction through hole.Handle 1 is also fixing through the through hole of torsion bar 4, can slide in hole and not deviate from.Housing is provided with groove, and the one side of slip insert 6 is provided with several longitudinal teeth, and another side is arc-shaped, and arc end is slightly larger than flank of tooth size, and do not come off in the openning that just can be stuck in housing 6, its arc surface coordinates with the arc groove of torsion bar 4.Gland 5 is arranged on the male end of housing 6, prevents torsion bar 4 from deviating from from housing 6.When left-handed or dextrorotation torsion bar 4, it is overhanging that the arc groove of torsion bar lower end will promote slip insert 7, and making on its groove inner surface being stuck in plug 2 and to sting tight, continuing to rotate torsion bar 4 can install plug 2 or unload.
