Description
One, technical field: the utility model relates to a kind of rod-pumped well well head tuningout sealing blowout hookup.
Two, background technology: in oilfield development process, the main at present mechanical oil production technology that adopts.The form of the sealer that the pumpingh well well head is used has multiple, and first kind is the sealed packing box of function singleness, and second kind is to have increased a well head tuningout function on having first kind basis, and the third is to have changed encapsulant and type shape on second kind basis.The sealer of the above three kinds of form all need be shut down when changing encapsulant, and complex structure easily causes environment pollution, does not reach ideal effect, and difficulty is bigger aspect applying.
Three, summary of the invention: the purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of wellhead deflection-regulating sealing blowout-preventing device for oil pumping machine well is provided.
Its technical scheme is: the utility model is made up of packing box, preventer and adjusting deviation device, it is characterized in that packing box is located at its top, and preventer is located at its middle and lower part, and adjusting deviation device is located at its underpart, and packing box, blowout prevention seat and tuningout body are made as one, same axle center; Packing box is tubular, which is provided with outer male thread, with set packing pressure cap threaded engagement, be made as Taper Pipe shape in it, which is provided with Taper Pipe shape packing gland, be provided with the rubber packing under the gland, its bottom is provided with the blowout prevention seat; Preventer is rounded, and the downward-sloping certain angle of an end is welded on packing box lower end outer circumferential side, which is provided with the pressure cap with its threaded engagement, week is provided with spring cavity in the pressure cap, is provided with helical spring in the chamber, is provided with steel ball or nonmetal ball under the spring; Adjusting deviation device is made up of tuningout body, tuningout seat and hold-doun nut, and tuningout body lower end external diameter is less than the external diameter of tuningout seat, greater than its internal diameter, the vertical pressure thereon, and spiro cap is fixed tuningout body and tuningout seat cooperating with male thread on the tuningout seat on the tuningout body.
Be provided with sawtooth downward sawtooth cannelure in some roads in the packing box week; Week be provided with concave station in the tuningout body, be provided with the nonmetal supporting positive cover of spill in the platform, the internal diameter of supporting positive cover is less than the diameter of blowout prevention spheroid; Nut is inverted concave, top internal diameter greater than tuningout body top external diameter, and all sides are provided with handle; The tuningout seat is divided into the clip head, with the well head clamp connection.
The utility model compared with prior art has advantage simple in structure, reasonable in design, that sealing is reliable, blowout prevention is sensitive, tuningout is conveniently feasible, has wide popularization market.
Four, description of drawings:
Fig. 1-section of structure of the present utility model.
Sequence number among the figure is expressed as respectively:
1-tuningout seat 2-nut handle 3-nut 4-tuningout body 5-supporting positive cover 6-prevents sprinkler body 7-helical spring 8-steel ball 9-preventer pressure cap 10-packing box 11-rubber packing 12-packing gland 13-pressure cap 14-blowout prevention seat
Five, the specific embodiment:
For further disclosing the technical solution of the utility model, below in conjunction with Figure of description, be described in detail by example: as shown in the figure: the utility model the utility model is made up of packing box 10, preventer 6 and adjusting deviation device, it is characterized in that packing box 10 is located at its top, preventer 6 is located at its middle and lower part, adjusting deviation device is located at its underpart, and packing box, blowout prevention seat 14 and tuningout body 4 are made as one, same axle center; Packing box 10 is tubular, which is provided with outer male thread, cooperate with set packing pressure cap screw thread 13, is made as Taper Pipe shape in it, which is provided with Taper Pipe shape packing gland 12, and gland is provided with rubber packing 11 under this, and its bottom is provided with spray seat 14; Preventer 6 is rounded, and the downward-sloping certain angle of an end is welded on packing box lower end outer circumferential side, which is provided with the pressure cap with its threaded engagement, week is provided with spring cavity in the pressure cap, is provided with helical spring 7 in the chamber, is provided with steel ball or nonmetal ball 8 under the spring; Adjusting deviation device is made up of tuningout body 14, tuningout seat 1 and hold-doun nut, tuningout body lower end external diameter is less than the external diameter of tuningout seat, greater than the internal diameter of its tuningout seat, vertically be pressed on the tuningout seat, spiro cap is cooperating with male thread on the tuningout seat on the tuningout body, tuningout body and tuningout seat are fixed.When using with on the tuningout seat or taper pipe thread be threaded with clamp connection or with platinotron with well head, nut 3 is enclosed within earlier on the tuningout body 4, preventer 6 in the welding, tuningout body 4 is inserted in wellhead polish rod with top, with the screw thread of nut and tuningout seat screw on several buttons, carry out tuningout, it is consistent with the axle center of polished rod that the axle center of packing box is transferred to, tightening nuts, and tuningout work is finished.Add the rubber packing, tighten the packing pressure cap, week hold polished rod tightly in the packing, outer periderm is got in the sawtooth of packing box.When the packing blow-by, twist the packing pressure cap again, compress packing, when adding packing, needs need not stop production, turn on the packing pressure cap, mention gland and just can add packing, get in the serrated slot because of remaining packing, can not ejected by oil, and good seal, can oil spout.During each tight packing, the lower end packing in the packing box can be worn into chip, falls in the oil, flows away with oil, so just need not get old packing outward when adding packing at every turn.Polished rod is disconnected aborning when taking off when oil well, and half of polished rod falls in the pit shaft, and half is proposed well head by oily machine; the black steel ball of sealer this moment is released by spring, is shifted onto on the seal receptacle by oily stream, and oil just can not spray outward; prevent the serious accident that causes because of blowout, protected natural environment.
