Abstract
The utility model relates to an oilfield mechanism which is a multi-function pumping well head rod packer used for sealing the polish rod of the pumping well. A packing gland nut is pressed on a packing set and the packing set and the packing gland nut are equipped in the up cap-shell. The lower part of the up cap-shell is connected with a seal valve though screw and the body of the seal valve is equipped with a sealing member which can be driven by a screw rod. The lower part of the seal valve is a sphere and the upper part of the sphere is provided with a sphere press cap. The sphere is equipped in the ball socket of the lower seal space and the sphere press cap is screwed with the lower seal space. As a result of adopting the dual free positioning mechanism of the globe joint and the translation body, the utility model has advantages of good adaptability for the movement of the polish rod, small drag friction and long service life. When changing the packing set, the utility model can close the seal valve. Closing the oil channel can reduce the loss of the crude oil.

Between last annular seal space and lower seal chamber, be connected with ball-joint, ball-joint comprises spheroid and spheroid pressure cap, the upper end of spheroid has the adapter cavity that can be threaded with last annular seal space, adapter cavity is sleeved in the spheroid pressure cap, have ball-and-socket on the translation pedestal in lower seal chamber, spheroid is installed in the ball-and-socket, and the spheroid pressure cap is threaded with the lower seal chamber.
Be connected with seal valve between last annular seal space and lower seal chamber, be provided with the seal that can be promoted by screw rod in the seal valve valve body, the valve body upper end is connected with last annular seal space, and the lower end is connected with the lower seal chamber.
Packing is up big and down small round platform, and its outside has the packing sheath.
The place that the top of translation pedestal is connected with the lower cylindrical body portion has a circle groove.
Base can be the body that is threaded, and also can be the clamp connection body.
Have sealing ring in the spheroid.
The outside of packing has the packing sheath.
Have handle socket on the outer circumference of locking jacket.
The utility model compared with prior art has following advantage:
(1) owing to having increased the spheroid coupling part, can be suitably crooked in 360 degree scopes, improved compliance to the polished rod motion.
(2) since the diameter of translation pedestal less than the internal diameter of pressing locking jacket thereon, the translation pedestal can be done radial motion in the 360 degree scopes with base, has further improved the compliance to the polished rod motion, reduces friction.
(3) when changing packing, can partly close polished rod sealer, reduce the crude oil loss, increase work efficiency by seal valve.
