Description
Technical field
The present invention relates to a kind of oil connection, belong to Hydraulic Field.
Background technique
Traditional oil connection is sealed by the principle compressing bolt or expansion bolt, but the compacting sealing mechanism of this rigidity after a 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: a kind of oil connection that to a certain degree can prevent the metal generation plastic deformation of joint is provided.
The present invention realizes by the following method:
A kind of oil connection, comprise adapter body and lock sleeve, described adapter body is hollow cylinder, axial one end of hollow cylinder is provided with apparatus connecting unit, the other end of hollow cylinder axis is provided with pipe connection portion;
The hollow cylinder outer wall of described pipe connection portion is provided with screw thread, described lock sleeve is connected on hollow body outer wall by thread bush, the hollow body inwall of described pipe connection portion is provided with spiral chute, in described spiral chute, be inlaid with coil spring, the hollow body wall of described pipe connection portion is provided with some straight-line grooves;
Described apparatus connecting unit is arranged 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 apparatus connecting unit, the hollow cylinder outer wall of apparatus connecting unit and pipe connection portion intersection is provided with annular groove, in the space that described ring-shaped depression and annular groove are formed, is 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, improves the effect of tensioner, and under also preventing 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, comprise adapter body 1 and lock sleeve 2, adapter body 1 is hollow cylinder, axial one end of hollow cylinder is provided with apparatus connecting unit 6, the other end of hollow cylinder axis is provided with pipe connection portion;
The hollow cylinder outer wall of pipe connection portion is provided with screw thread, lock sleeve 2 is connected on hollow body outer wall by thread bush, the hollow body inwall of pipe connection portion is provided with spiral chute, is inlaid with coil spring 5 in spiral chute, and the hollow body wall of pipe connection portion is provided with some straight-line grooves;
Apparatus connecting unit 6 is provided with the screw thread with equipment connection;
Lock sleeve 2 is coaxially arranged with ring-shaped depression towards one end of apparatus connecting unit 6, apparatus connecting unit 6 with the hollow cylinder outer wall of pipe connection portion intersection is provided with annular groove, in the space that ring-shaped depression and annular groove are formed, is filled with stuffing box packing 3;
In order to prevent tube wall 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.
During use, first locking ring is pulled down, be inserted in packing press ring, filler is added in annular groove, be inserted in oil pipe in the straight-line groove position of pipe connection portion simultaneously, screwed in by lock sleeve subsequently by screw thread, filler is finally filled in the toroidal cavity of screw thread and annular groove and ring-shaped depression composition, realize sealing, finally whole joint is fixed to equipment.
