Description
Technical field
The utility model relates to a kind of joint, particularly, relates to a kind of swivel joint.
Background technique
Coiled tubing work vehicle belongs to mobile unit truck, and swivel joint is one of requisite vitals on coiled tubing work vehicle, and its effect is exactly under high pressure can rotate, and can seal completely again, non-leakage.
Model utility content
The utility model, in order to solve the above-mentioned defect and deficiency that exist in prior art, provides a kind of swivel joint, overcomes the technical barrier being difficult to because high pressure causes solid of rotation to bear very large axial force when construction operation rotate.
For solving the problems of the technologies described above, the utility model provides a kind of swivel joint, comprise solid of rotation and permanent joint, described solid of rotation is connected with permanent joint, described solid of rotation upper end portion is provided with joint upper cover, the trough of described solid of rotation cylindrical is connected with fixture block, and described fixture block is provided with rolling bearing, and described rolling bearing is provided with tapered roller bearing; Be provided with sealing seat below described fixture block, be provided with filler below described sealing seat, described filler is provided with Gland nut, and described filler has pad; Described permanent joint is provided with internal thread, and described permanent joint is provided with gland, and described gland is provided with the outside thread matched with permanent joint internal thread; Described solid of rotation is provided with lubricating cup, and described lubricating cup is connected with tapered roller bearing with described rolling bearing respectively; Described permanent joint is provided with movable slips, and described movable slips has the tight cap of the union be connected with external lug.
Further, O-ring seals two and O-ring seals three is respectively equipped with in described sealing seat.
Further, O-ring seals one is provided with outside described sealing seat.
Further, the bottom of described filler is provided with O-ring seals four.
Further, described movable slips is provided with the back-up ring preventing movable slips from coming off.
Further, dust cover is provided with above described tapered roller bearing.
Further, the material of described filler is nitrile rubber.
Further, be also fixedly linked by fastening screw trip bolt between described gland and described permanent joint.
The Advantageous Effects that the utility model reaches: the utility model adopts tapered roller bearing, overcome the technical barrier being difficult to because high pressure causes solid of rotation to bear very large axial force when construction operation rotate, tapered roller bearing can bear larger radial force also can bear larger axial force, therefore significantly reduce the load that solid of rotation under high pressure rotates, improve working life; In addition, adopt integrated type permanent joint, avoid the risk that joint causes because of welding quality; And, O-ring seals is set in the bottom of filler, substantially increases the sealability of solid of rotation, extend working life.
