Abstract
The invention relates to an oil pipe joint. The oil pipe joint comprises a joint body and a locking sleeve. The joint body is a hollow cylinder, an equipment connection part is arranged at one axial end of the hollow cylinder, and a pipeline connection part is arranged at the other axial end of the hollow cylinder. Threads are arranged on the hollow-cylinder outer wall of the pipeline connection part, and the locking sleeve is connected to the hollow-cylinder outer wall in a sleeved mode through the threads; a spiral groove is formed in the hollow-cylinder inner wall of the pipeline connection part, and a coil spring is embedded into the spiral groove; a plurality of line grooves are formed in the hollow-cylinder wall surface of the pipeline connection part. The equipment connection part is arranged according to specific working conditions of equipment. Because the coil spring can be additionally arranged in the inner wall of an expansion bolt, the expansion effect is improved, and influence of plastic deformation of joint metal under long-time pressing on the sealing effect is avoided as well.
Description
Technical field
The present invention relates to a kind of oil connection, belong to Hydraulic Field.
Background technique
Traditional oil connection seals by the principle that compresses bolt or expansion bolt, but the compacting sealing mechanism of this rigidity is after long-time use, can produce leakage because of the plastic deformation of metal, produces dangerous.
Summary of the invention
The object of the invention is to: the oil connection that a kind of metal generation plastic deformation that can to a certain degree prevent joint is provided.
The present invention realizes by the following method:
A kind of oil connection, comprises adapter body and lock sleeve, and described adapter body is hollow cylinder, is provided with equipment connection portion in axial one end of hollow cylinder, is provided with pipeline joint at the axial the other end of hollow cylinder;
The hollow cylinder outer wall of described pipeline joint is provided with screw thread, described lock sleeve is connected on hollow body outer wall by thread bush, the hollow body inwall of described pipeline joint is provided with spiral chute, in described spiral chute, be inlaid with coil spring, on the hollow body wall of described pipeline joint, be provided with some straight-line grooves;
Described equipment connection portion arranges according to the concrete operating mode of equipment.
As further innovation of the present invention, described lock sleeve is coaxially arranged with ring-shaped depression towards one end of equipment connection portion, on the hollow cylinder outer wall of equipment connection portion and pipeline joint intersection, be provided with annular groove, in the space of described ring-shaped depression and annular groove formation, be filled with stuffing box packing.
As further innovation of the present invention, described annular groove top is also socketed with packing press ring.
beneficial effect
The present invention adds coil spring at expansion bolt inwall, has improved the effect of tensioner, also prevents that under long-time compressing, joint metal generation plastic deformation affects sealing effect simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is right elevation of the present invention.
Embodiment
Be described further below in conjunction with accompanying drawing
A kind of oil connection, comprises adapter body 1 and lock sleeve 2, and adapter body 1 is hollow cylinder, is provided with equipment connection portion 6 in axial one end of hollow cylinder, is provided with pipeline joint at the axial the other end of hollow cylinder;
The hollow cylinder outer wall of pipeline joint is provided with screw thread, lock sleeve 2 is connected on hollow body outer wall by thread bush, the hollow body inwall of pipeline joint is provided with spiral chute, is inlaid with coil spring 5 in spiral chute, on the hollow body wall of pipeline joint, is provided with some straight-line grooves;
Equipment connection portion 6 is provided with the screw thread with equipment connection;
In order to prevent that tube wall is thicker, lock sleeve 2 cannot be rotated in place, and for filler provides good compression, annular groove top is also socketed with packing press ring 4.
When use, first locking ring is pulled down, be inserted in packing press ring, in annular groove, add filler, be inserted in oil pipe in the straight-line groove position of pipeline joint, by screw thread, lock sleeve screwed in subsequently, filler is finally filled in the toroidal cavity of screw thread and annular groove and ring-shaped depression composition simultaneously, realize sealing, finally whole joint is fixed to equipment.
