Abstract
A rotary seal joint mainly comprises an upper joint (1), a seal ring (2, 5), a fixed bolt (3), a rolling steel ball (4), and a lower joint (6). The outer diameter of the upper joint (1) is processed with steps, the lower joint (6) is sleeved on the steps, and matches with the steps in a clearance way; Corresponding to position of the steps, the lower joint (6) is provided with a plurality of through holes along the circle direction, the inner of the through holes is provided with the rolling steel ball (4) and the fixation bolt (3); the upper joint (1) is provided with half-round cross-section ring grooves which are corresponding to the position of the through holes, and matched with the rolling steel ball (4), two sides of the rolling steel ball (4) are provided with a seal ring (2, 5) respectively. The structure of the utility model is simple, the action is reliable, the upper and the lower joint can mutually rotate without the limitation of direction and number of turns, the rolling steel ball in the corresponding groove limits the mutual movement of the upper and the lower joints in axis direction, the utility model can be in the rotation while maintaining hydraulic seal.
Description
Technical field
The utility model relates to the down-hole aid that oil-gas field development uses in the petroleum industry, belongs to the downhole tool class.
Background technology
In the petroleum industry in the oil-gas field development operation process, the situations that different instruments need have difference to move on the underground work tubing string often appear, need rotate and the lower tube string need keep static as the upper tube string, and whole instrumentation tubes string need keep hydraulic seal, to realize separation last lower tubular column.
Summary of the invention
Need keep static and whole instrumentation tubes string need keep the difficult problem of the operation of hydraulic seal for the upper tube string that solves the underground work tubing string need rotate the lower tube string, the utility model provides a kind of rotatory sealing joint.
The utility model mainly is made up of top connection 1, sealing ring 2,5, set bolt 3, rolling steel ball 4, lower contact 6, is processed with step on top connection 1 external diameter, and lower contact 6 is sleeved on the step, and the two is a matched in clearance; Corresponding step position, lower contact 6 upper edges circumferentially have several through holes, and rolling steel ball 4 and set bolt 3 are housed in the through hole; The position of top connection 1 corresponding through hole has the cannelure that the cross section is a semicircle shape, is complementary with rolling steel ball 4; The both sides of rolling steel ball 4 have sealing ring 2,5 respectively.
Simple in structure, the reliable in action of the utility model, upper and lower joint can relatively rotate, and no rotation direction or the restriction of the rotation number of turns rely on the rolling steel ball in its mutual corresponding groove to limit its mutual axially-movable, still can keep hydraulic seal simultaneously in rotation.
