Abstract
The utility model discloses a universal ball type polish rod sealer of a pumping well, which comprises a clamp head, an offset adjusting body, a screw sleeve, a lower sealing gasket, a bulb, upper sealing gaskets, a packing box, a rubber gate and adapter connectors. The packing box and the rubber gate of the universal ball type polish rod sealer disclosed by the utility model are the same with the packing box and the rubber gate of an original polish rod sealer, and are provided with central holes; the adapter connectors at the lower ends of the packing box and the rubber gate are provided with internal screw threads; and the upper sealing gaskets which are made of metal are embedded at the upper parts of the packing box and the rubber gate. The offset adjusting body which is circular tube-shaped is provided with a central hole, and the bulb is arranged at the upper part of the offset adjusting body. The lower sealing gasket made of metal is embedded at the upper part of the screw sleeve which is hexagonal. The screw sleeve is sleeved from the lower end of the offset adjusting body to be connected with the adapter connectors through screw threads so as to clamp the bulb. External screw threads are arranged at the lower end of the offset adjusting body and are connected with the internal screw threads of the clamp head. The universal ball type polish rod sealer is simple in structure, easy to manufacture and low in price; the central angular displacement of the universal ball type polish rod sealer can reach 0-6 degrees; the rated working pressure of the universal ball type polish rod sealer is 10Mpa; the packing is long in service life; the universal ball type polish rod sealer has the advantages of friction load is reduced, the loss of crude oil is reduced, environment pollution is effectively prevented, the oil well management level is improved and the labor intensity of the workers is lightened.
Description
Technical field
The utility model relates to well rod and well head tuningout centralising device, particularly is a kind of pumpingh well universal ball polished rod sealer.
Background technology
Rod-pumped well because well head surface line or oil pumper immerge, causes polished rod and well head deflection in process of production, makes polished rod and well head packing eccentric wear, not only shortens packing application life, and causes well head leakage of oil, contaminated environment.Thereby the tuningout centering of well head is a great problem of rod-pumped well management, on-the-spot through school machine, adjustment beam-pumping unit axis jackscrew, the tuningout well head be installed realized.School machine, adjustment beam-pumping unit axis jackscrew workload are big, the inconvenience adjustment, and existing tuningout shaft collar is complicated, and expensive is difficult to apply.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of pumpingh well universal ball polished rod sealer is provided.
Above-mentioned purpose is realized by following technical proposals:
The utility model technical scheme comprises: clip head, tuningout body, silk braid, lower seal pad, bulb, last sealing mat, packing box, rubber gate, joint.Packing box, the rubber gate of its pumpingh well universal ball polished rod sealer are identical with former polished rod sealer, are provided with centre bore, and the bottom joint is provided with internal thread; Top studs with sealing mat on the metal, and pipe shape tuningout body is provided with centre bore, and top is provided with bulb; The silk braid top that is provided with six sides studs with metal lower seal pad, and silk braid is inserted in joint screw thread from tuningout body bottom and is connected, and compresses bulb; Tuningout body lower end is provided with external screw thread, is connected with the internal thread of clip head.
The beneficial effect of the utility model is: simple in structure, easy to manufacture, cheap; The central angle displacement can reach 0～6 °, rated operating pressure 10Mpa, and oil pumping polish rod and well head centering are effective; The packing long service life, the load that reduces friction reduces the crude oil loss; Effectively prevent the pollution of the environment, improve the oil well management level, alleviate working strength of workers.
Description of drawings
Accompanying drawing is that the utility model master looks the broken section structural representation.
Among the figure, 1-clip, 2-tuningout body, 3-silk braid, 4-lower seal pad, 5-bulb, the last sealing mat of 6-, 7-packing box, 8-rubber gate, 9-joint; The A-steel ring slot, the B-centre bore.
The specific embodiment
Below in conjunction with accompanying drawing further elaboration is done in the enforcement of the utility model:
Pumpingh well universal ball polished rod sealer is made up of clip head 1, tuningout body 2, silk braid 3, lower seal pad 4, bulb 5, last sealing mat 6, packing box 7, rubber gate 8, joint 9.Its packing box 7, rubber gate 8 are identical with former polished rod sealer, are provided with centre bore B, and bottom joint 9 is provided with internal thread; Top studs with sealing mat 6 on the metal, and pipe shape tuningout body 2 is provided with centre bore B, and top is provided with bulb 5; Silk braid 3 tops that are provided with six sides stud with metal lower seal pad 4, and silk braid 3 is inserted in joint 9 from tuningout body 2 bottoms and is threaded, and compresses bulb 5; Tuningout body 2 lower ends are provided with external screw thread, are connected with the internal thread of clip head 1.
Mounting method: at first, stop oil pumper, load removal is dismantled former polished rod sealer; Secondly, be inserted in pumpingh well universal ball polished rod sealer from polished rod, put steel ring between clip head 1 and the well head threeway, the card front band tightens set bolt; The 3rd, on carry dead space, polished rod is connected with polished rod eye; The 4th, added packing, silk braid 3 and joint 9 are tightened, then polished rod and pumpingh well universal ball polished rod sealer align.
