Description

Two ball tuningout well head packing box integral type plugging devices
Technical field
The utility model belongs to sealing device, particularly relates to a kind of pair of ball tuningout well head packing box integral type plugging device.
Background technology
In oil extraction process, because oil pumper is worked under varying duty for a long time, very easily cause the suspension point track of oil pumper and tubing string axis to depart from, cause sucker rod partial wear in the oil recovery process, therefore, the well head packing box is main anti-inclined to one side, blowout prevention instrument.And existing packing box is because unreasonable structure, exist tuningout weak effect, packing utilization rate low, change the packing cycle short, increased labor strength, prolonged maintenance time, reduced oil recovery efficiency, increased cost for oil production.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of pair of ball tuningout well head packing box integral type plugging device is provided.
Of the present utility model pair of ball tuningout well head packing box integral type plugging device is to be made of gland, pressure cap, packing group and universal joint.The packing group places in the upper cardan, and pressure cap compresses the packing group and has gland to compress pressure cap and connects with upper cardan bar spiral shell button; The upper cardan bulb is seated in the ball seat suitable for reading of lower cardan bar, upper cardan cap cutting ferrule connects on the upper cardan bulb and with lower cardan bar screw thread tight fit, the lower cardan bulb is seated in the ball seat suitable for reading of well head short circuit, and lower cardan cap cutting ferrule is buckled to screw on the lower cardan bulb and with well head short circuit spiral shell and connected.
As further improvement of the utility model, in the cavity of upper cardan, be divided into the equal chamber section on top and the awl chamber section of bottom according to its internal diameter.
As further improvement of the utility model, the packing group in the section of universal pitch cone chamber from top to bottom its external diameter is contraction-like along with reducing of awl chamber section internal diameter.
As further improvement of the utility model, the upper cardan cap is suitable for reading all to be embedded with spherical seal ring with the sphere place that contacts the upper cardan bulb suitable for reading of lower cardan bar.
As further improvement of the utility model, the lower cardan cap is suitable for reading all to be embedded with spherical seal ring with the sphere place that contacts the lower cardan bulb suitable for reading of well head short circuit.
The of the present utility model pair of ball tuningout well head packing box integral type plugging device tuningout is effective, packing utilization rate height, need not to change packing, simple in structure, easy to maintenance.
Description of drawings
Figure of description is the structural representation of of the present utility model pair of ball tuningout well head packing box integral type plugging device.
