Abstract
The utility model relates to a self adjustable anti-spurting box of the smooth roll arranged on the mechanical oil well head. A base tube (1) is connected to the wax cleaning sluice of the mechanical oil well head, the smooth roll goes through the wax cleaning sluice after the wax cleaning sluice is connected with a compression nut. A seal gasket (2), an eccentric adjustment seat (3), a sealing cup (4), a packing tube (5), a spring seat (7), a spring (8), and a spring press cap (9) are orderly seated in a base tube and formed a sealing packing box in the formed ring-shaped containment room. A groove (12) is arranged on the eccentric adjustment seat, and an axial groove (14) is arranged on the packing tube body, so the moving range is enlarged.
Description
The utility model relates to a kind of blowout prevention box that is used between oilfield pumping well well head and the polished rod, and it belongs to sealing device.
Rod-pumped well on the oil field, excessive for the crude oil of avoiding the down-hole to be drawn up in polished rod (sucker rod) pumps process, need to settle sealing device at well head; In addition, wellhead equipment and oil pumper cause polished rod to make it the eccentric wear packing in the process of pumping owing to reason or other reason of down-hole are installed, and the sealing performance of sealing device is descended.At present more advanced is automatic deflection adjusting blowout prevention box, adopt binodal, holddown spring to be loaded on the inside and outside separation seal of packing tube respectively, in the room of packing tube bottom ball seal after connecting by base tube, clamping nut, its complex structure, assembling back body body is longer, and cost is higher, is difficult for installing and debugging, bring difficulty for the replacing sealed packing, the scope of self-regulated simultaneously is less.
The purpose of this utility model is to overcome above-mentioned shortcoming part of the prior art, and a kind of Installation and Debugging simple in structure, easy, the convenient and bigger rod-pumped well wellhead polish rod self-regulated blowout prevention box of self-regulated scope of replacing sealed packing are provided.
The purpose of this utility model can reach by following measure: by the base tube with after clamping nut is connected, passed by polished rod, sitting successively in the annular room that forms has sealing mat, off-centre to adjust seat, obturating cup, packing tube, packing, spring base, spring, spring pressure cap formation sealed packing box.
The purpose of this utility model can also reach by following measure: adjust on seat ［ 3 ］ body fluted ［ 12 ］ in off-centre, on packing tube ［ 5 ］ body axial groove ［ 14 ］ is arranged, spring pressure cap ［ 9 ］ is eccentric pressure cap.
Be further described below in conjunction with accompanying drawing:
Fig. 1 is a rod-pumped well wellhead polish rod self-regulated blowout prevention box structure principle chart;
Fig. 2 is eccentric main section, the vertical view looked of seat ［ 3 ］ of adjusting on Fig. 1;
Fig. 3, the 4th, packing tube ［ 5 ］, main section, the vertical view looked of spring pressure cap ［ 9 ］ on Fig. 1;
By shown in Figure 1, on rod-pumped well well head paraffin valve, connect base tube ［ 1 ］, it is connected the back and is passed by polished rod ［ 13 ］ with clamping nut ［ 10 ］, in the annular room that forms, be seated at successively sealing mat ［ 2 ］ arranged on base tube ［ 1 ］ the body internal projecting ring, eccentricly adjust seat ［ 3 ］, an obturating cup ［ 4 ］, packing tube ［ 5 ］, packing ［ 6 ］, spring base ［ 7 ］, spring ［ 8 ］, spring pressure cap ［ 9 ］ constitutes the sealed packing box; Wherein:
Adjust seat ［ 3 ］ in off-centre and go up fluted ［ 12 ］, after being seated at sealing mat ［ 2 ］ and going up, its eccentric direction can be according to actual conditions, and insert arbitrarily to dial in the groove ［ 12 ］ with instrument changes;
The interior sabot root of packing tube ［ 5 ］ ［ 6 ］ has axial groove ［ 14 ］ on the cylindrical shell, as shown in Figure 3, cylindrical shell has annular room outward, makes packing tube ［ 5 ］ with polished rod ［ 13 ］ activity certain self-regulated scope be arranged;
Have annular that groove is installed in spring base ［ 7 ］ outside, in addition, spring pressure cap ［ 9 ］ is eccentric pressure cap, and gapped ring ［ 11 ］ between polished rod.
During assembling, except that packing ［ 6 ］, earlier sealing mat ［ 2 ］, eccentric adjustment seat ［ 3 ］, an obturating cup ［ 4 ］, packing tube ［ 5 ］ are seated in the end seat tube ［ 1 ］ successively; In advance spring base ［ 7 ］, spring ［ 8 ］ are placed in the packing tube ［ 5 ］, spring pressure cap ［ 9 ］ is pressed thereon, connects clamping nut ［ 10 ］, constitutes the blowout prevention box of non-stuffing, lays in stand-by; During use, this blowout prevention box is connected on the rod-pumped well well head paraffin valve, passed by polished rod, unclamp clamping nut ［ 10 ］, packing tube ［ 5 ］ is proposed base tube ［ 1 ］ along polished rod ［ 13 ］, again spring in the packing tube ［ 8 ］ and spring base ［ 7 ］ are proposed on the packing tube ［ 5 ］, be equipped with packing according to the polished rod diameter then and place sealing in the packing tube ［ 5 ］, after this according to the well head actual conditions, adjust the eccentric direction of adjusting seat ［ 3 ］, its upper groove ［ 12 ］ is fixed in a certain side, at last packing tube ［ 5 ］ is set back, firmly be connected on the base tube ［ 1 ］ with hadle clamping nut ［ 10 ］, its inner member compresses sealing successively.
Compare with at present advanced automatic deflection adjusting blowout prevention box, the utlity model has following advantage:
1. structure is simpler: by tube at the bottom of the existing packing box of base tube ［ 1 ］ replacement, directly connect clamping nut, shortened length, reduce by 7 members, form the single-unit sealing, have suitable to guaranteeing the blowout prevention box perpendicularity;
2. improved self-regulated flexibility and scope of activities: packing tube ［ 5 ］ bottom spheroid is changed into by secure fit and contacts cooperation, and eccentric room increases between eccentric adjusting seat ［ 3 ］ and base tube ［ 1 ］, leave annular room between packing tube ［ 5 ］ and base tube, polished rod ［ 13 ］ and sealing gasket ［ 2 ］, eccentric adjusting seat ［ 3 ］, obturating cup ［ 4 ］, spring pressure cap ［ 9 ］, gap between the clamping nut ［ 10 ］ is enlarged, owing to wellhead equipment and oil pumper installation or other reason of down-hole, cause when making polished rod or production tree deflection, above-mentioned measure can make the polished rod scope of activities enlarge, improve the self-regulated flexibility, reduce polished rod to the wearing and tearing of packing in the blowout prevention box, prolong the service life of packing.
