Abstract
The utility model relates to a universal automatic deviation correcting well head tee which is used for the well head of the pumping well in oil fields. The utility model overcomes the shortages of multi-angle deviation or displacement which is easily caused on the transverse and the longitudinal connecting positions of the present integrated well head tee in butt joint on the spot, eccentricity of the packing box of the well head and the polishing rod, and inconvenient installation. The utility model is characterized in that the loosed flange slice is externally sheathed on the inner side spherical surface of a spherical surface connecting body, one end of the spherical surface connecting body is in screwed connection with the transverse part of the tee, and the surface of the other end of the spherical surface connecting body is spherical; the lower end of the longitudinal part of the tee is connected with a connecting sphere, the external surface of which is spherical, and a connecting press cap externally sheathed between the tee and the connecting sphere; the lower part of the connecting press cap is connected with the well head.
Description
The utility model relates to a kind of threeway that is used for oil field pumping well well head position, the inclined to one side well head threeway in particularly a kind of school automatically.
Existing well head threeway standard piece, its horizontal and vertical two-part are inseparable single piece, and the flange of transverse end is connected with well head oil transportation process pipelines, and the upper end of longitudinal component is connected with packing box is vertical, and the lower end is connected with the production tree central vertical.Owing to be integral piece, in the field joint laterally and longitudinally connection part easily produce the deviation or the inconsistent phenomenon of multi-angle, cause well head packing box and polished rod decentraction, and have the easy to wear and problem of leakage of oil of inconvenience, polished rod and packing of installing.
But the purpose of this utility model is to design a kind of laterally scalable and horizontal and vertical all inclined to one side well head threeways in multi-angle school, promptly universal automatic deviation correcting wellhead wye.
The utility model comprises laterally and is vertical to be the threeway of one, its main points are: the lateral part of threeway and an end are screw thread the other end outer surface for the screw thread end of spherical sphere connecting body spins, and center hole is coated on the inboard sphere of sphere connecting body less than the loose flange sheet of sphere diameter; Outer surface is the lower end that spherical connection ball is connected in the threeway longitudinal component, connects pressure cap and is coated between the two, and its underpart is connected with the ball seat body.The ball seat body is used for being connected with the production tree of well head.Owing to the loose flange sheet and connect the outer surface that pressure cap all is socketed on spheroid and form flexible connection, but make they respectively with respect to threeway laterally and vertical position multi-angle tuningout, and the one section screw thread that spins between sphere connecting body and threeway makes the distance that one section transversal stretching has been arranged between them mutually.
Compared with prior art, the utility model has overcome the horizontal deficiency that vertically is fixed-direction and horizontal non-telescoping existence that reaches in the prior art, can correct wellhead flange dislocation connection and packing box and polished rod deviation, be convenient to install and add packing and operate the life cycle that can prolong packing.
Below in conjunction with accompanying drawing the utility model and embodiment are made a brief description:
Fig. 1 is the utility model structural representation.
By one section screwed connection, the length of this section screw thread has determined horizontal telescopic distance between them between the lateral part of sphere connecting body 1 one ends and threeway 5; The outer surface of the other end of sphere connecting body 1 is a spheroid form, center hole is coated on the inboard sphere of sphere connecting body 1 less than the loose flange sheet 2 of sphere diameter, the internal surface of the center hole of loose flange sheet 2 should be with relative with outer surface of spheroid, but because it does not play sealing and other effect, therefore can be not corresponding with corresponding sphere yet, but the diameter in hole must be less than the diameter of spheroid; The lower end of threeway 5 longitudinal components also is the connection ball 10 of spheroid form by the screwed connection outer surface, Placement also can adopt horizontal punching back to embed method or other non-screwed connection method of pin, connect pressure cap 9 and be coated at and connect between ball 10 and the threeway 5, and itself and the aperture that is connected ball 10 socket places are less than the external diameter of connection ball 10; Ball seat body 11 lower ends are used for being connected with production tree, the upper end be connected that pressure cap 9 bottoms articulate or screw thread spins.Sealing gasket 3, sealing press tongue 4, seal ring 6, seal ring 7, seal ring 8 and seal ring 12 etc. all to seal.Be spheroid form with loose flange sheet 2 and the position that is connected 9 sockets of pressure cap, but make their activities, promptly played the inclined to one side effect in multi-angle school at the scene with respect to threeway 5 equal multi-angles.
