Accompanying drawing explanation
Fig. 1 is the structure chart of eccentric abrasion prevention blowout prevention box in the utility model embodiment.
Detailed description of the invention
The utility model provides a kind of eccentric abrasion prevention blowout prevention box, bends to solve polished rod in prior art the technical problem that eccentric wear blowout prevention box causes blowout prevention box seal failure.
Technical scheme in the embodiment of the present application is solve above-mentioned technical problem, and general thought is as follows:
Provide a kind of eccentric abrasion prevention blowout prevention box, comprising: base, described chassis interior is provided with through hole; Guard shield holder, is welded in the middle part of described chassis outer side; Guard shield, is welded in above described guard shield holder; High-pressure hose, is fixed on above described base; Blowout prevention pressure cover, is fixed on described high-pressure hose top; Polished rod hole, is arranged in the middle part of described blowout prevention pressure cover; Two pressure-bearing holders, are oppositely arranged at described guard shield top, and the width between described two pressure-bearing holders is greater than the diameter of polished rod.And then when being coordinated polished rod seal well head by this eccentric abrasion prevention blowout prevention box, polished rod can be penetrated from through hole and pass from polished rod hole, after polished rod is bending, high-pressure hose top is with polished rod transverse shifting, the polished rod seal well head of distortion can be coordinated, and then prevent polished rod from causing eccentric wear to this eccentric abrasion prevention blowout prevention box, reach the technique effect keeping sealing.Thus the pollution of equipment and environment can be avoided further.
In order to better understand technique scheme, below by accompanying drawing and specific embodiment, technical solutions of the utility model are described in detail, the specific features being to be understood that in the utility model embodiment and embodiment is the detailed description to technical solutions of the utility model, instead of the restriction to technical solutions of the utility model, when not conflicting, the technical characteristic in the utility model embodiment and embodiment can combine mutually.
The utility model embodiment provides a kind of eccentric abrasion prevention blowout prevention box, please refer to Fig. 1, comprising:
