Ensure to protect primary seal between cable and hanger, this two seals is not conventional seal structure, and its sealing difficulty is big, often
Often there is the problem of oil stream seepage, cause well head to pollute, can also influence electric pump oil well production.
The content of the invention
The purpose of this utility model is a kind of Well head device for electric pump well of design, the problem of making it overcome prior art to exist,
Make its sealed reliable, convenient installation.
What the purpose of this utility model was realized in：Including suspension joint, cable duct tube, pressed joint, gland, cable
Seal, joint, support tube, anchor tip, flange, the bottom of suspension joint and the top of flange connect, inside suspension joint
There is twice tubing round thread, the bottom of anchor tip is connected with flange, and the endoporus of anchor tip communicates with the lower cavity of flange, Gu
The axis of joint is determined in the outside of the axis of flange, and the extended line of the axis of anchor tip and the axis of flange has intersection point, makes solid
Determine that the axis of joint is inclined, joint is set with from the bottom of support tube, the top connection support tube of anchor tip, support tube
Top endoporus be conical bore, have the cable aperture described in three in cable seal, described three cable aperture are uniformly distributed, will
Cable seal is cut into uniform three and broken, and tangent line intersects by the center of circle of cable aperture on the axis of cable seal, there is circle
The cable seal of cone outer wall is placed in the upper cone hole of support tube, the cone of cable seal and support tube it is upper
Portion's conical bore fitted seal, gland clasp cable seal, and joint entangles gland, and cable duct tube liner is in pressed joint, pressure
Tight coupling is connected with joint screw thread, and interior shoulder and the outer shoulder in support tube of joint mount, and make its pressed joint and joint phase
To that can be compressed or releases cable seal during rotation.
Keyway is set outside support tube top, and gland entangles keyway, and pin, the described keyway of pin insertion are installed on gland
In, gland is axially moved, it is impossible to rotary motion.
The beneficial effects of the utility model are：The bottom of suspension joint is threadedly coupled with the top of flange, junction it is close
Envelope is easily guaranteed that cable seal encases cable and is easily guaranteed that sealing through screw thread compacting, and flange on well head with being sealed into steel ring
Sealing, is mature technology, therefore, the utility model sealed reliable, overcomes the problem of prior art is present, electric motor drive oil pump system well head
Will not seepage, do not pollute the environment, can guarantee that electric pump producing well normally produces, there is significant economic benefit.
Brief description of the drawings
Fig. 1 is the installation diagram of the utility model embodiment.
Fig. 2 is the upper surface perspective view of part 5 in Fig. 1.
Embodiment
Embodiment of the present utility model is illustrated with reference to Fig. 1.
As shown in Figure 1, embodiment of the present utility model include suspension joint 1, cable duct tube 2, pressed joint 3, gland 4,
Cable seal 5, joint 9, support tube 10, anchor tip 11, flange 12, the bottom of suspension joint 1 connect with the top of flange 12
Connect（Threaded connection, junction ensure sealing）, there is twice tubing round thread, lower road sealing and OIH Guan Lian inside suspension joint 1
Connect, upper track is sealed for connecting lifting sub, is easy to lift tubing string G.I.H, bottom and the flange 12 of anchor tip 11 connect
Connect, assemble for the ease of processing and communicated using welding, the endoporus of anchor tip 11 with the lower cavity of flange 12, anchor tip 11
Axis in the outside of the axis of flange 12, the extended line of the axis of anchor tip 11 and the axis of flange 12 has intersection point（Two axles
The angle of line is 20-30, makes the axis of anchor tip 11 inclined, and gradient is advisable with good tripping in cable, joint 9 from
The bottom suit of support tube 10, the top connection support tube 10 of anchor tip 11, the top endoporus of support tube 10 is conical bore, electricity
There is the cable aperture 6 described in three on cable seal 5, described three cable aperture 6 are uniformly distributed, cable seal 5 is cut into
Uniform three break, and tangent line intersects by the center of circle of cable aperture 6 on the axis of cable seal 5, there is the cable of cone outer wall
Seal 5 is placed in the upper cone hole of support tube 10, the cone of cable seal 5 and the upper cone hole of support tube 10
Fitted seal, gland 4 clasp cable seal 5, and joint 9 entangles gland 4, and the liner of cable duct tube 2 compresses in pressed joint 3
