Technical field
The utility model is related to oilhydraulic engineering field, and in particular to a kind of oil connection.
Background technology
The situation for docking two oil pipes can be usually run into when installing or connecting oil circuit, it is how that two oil pipes are quickly firm
Solid link together, how prevent leakage, be all problems faced.In the prior art, the connection of oil pipe, is connect by oil pipe
What head was attached.Chinese invention patent CN106247045A discloses a kind of oil connection, and the oil connection includes joint sheet
Body, connecting tube and nut, joint body are that the through hole that feed flow force feed passes through is provided with cylindrical structural, joint body, joint
One end of body is provided with cone-shaped groove, and one end of connecting tube is plugged in groove, and nut sleeve is in connecting tube and with connecting
Female connector body is threadedly coupled, and is provided with sealing ring on the end face and/or circular conical surface of one end that connecting tube is plugged in groove, is passed through
Sealing ring realizes the sealing between joint body and connecting tube.
This oil connection in use, it is necessary to by the conical surface of both joint body and connecting tube carry out positioning and
Sealing, if the cone face process that both are engaged is unqualified, can cause sealing ring to damage and joint body and connecting tube
The cooperation cone face process precision that junction often occurs in permeability phenomenon, therefore this pipe joint butt joint body and connecting tube will
Ask higher, overall manufacturing cost is higher.
Utility model content
The utility model purpose is：There is requirement on machining accuracy height for oil connection of the prior art and cause production
The problem of product manufacturing cost is higher is there is provided a kind of oil connection, and the oil connection requirement on machining accuracy is low, and manufacturing process is simple,
Cost of goods manufactured can effectively be reduced.
To achieve these goals, the technical solution adopted in the utility model is：
Clamping cap, the clamping cap are arranged with outside a kind of oil connection, including joint body and connecting tube, the connecting tube
It is provided with external screw thread, joint body and is correspondingly provided with internal thread, the connection tube end outward flanging formation compressed part, the pressure
The external diameter in tight portion is less than the diameter of internal thread on joint body, and sealing gasket is provided between the compression end surface and joint body.
Promote connecting tube to be moved to joint body by screwing clamping cap, compress compressed part and be located at compression end surface with connecing
Sealing gasket is provided between head body, so as to realize the sealing to oil pipe junction, prevent leakage is used due to the oil connection
It is flat seal mode, sealing effectiveness is played after bringing it about deformation by compressing sealing gasket, thus can reduces related zero
The requirement on machining accuracy of part, simplifies manufacturing process, can effectively reduce cost of goods manufactured, also reduces product later maintenance cost,
Extend oil connection service life.
As preferred scheme of the present utility model, anaerobic sealer is scribbled between the external screw thread and internal thread.By
Anaerobic sealer is applied between screw thread pair, further the junction of oil connection can so be sealed after joint installation,
Prevent leakage.
As preferred scheme of the present utility model, the material of the sealing gasket is red copper.Because red copper material is softer, by
It can be deformed after power extruding, you can realize better seal effect, while red copper pad can bear higher temperature and pressure,
Be not in cause the situation of seal failure because of HTHP.
As preferred scheme of the present utility model, the clamping cap, which is provided with, is used for the clamping part that spanner is tightened, the folder
Portion is held for outer hexagonal prism.It is easy in clamping cap precession joint body using such design by spanner, pacifies joint
Dress is more convenient and strength-saving.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
1st, by screw clamping cap promote connecting tube moved to joint body, make compressed part compress be located at compress end surface with
Sealing gasket is provided between joint body, so that the sealing to oil pipe junction is realized, prevent leakage, because the oil connection is used
Be flat seal mode, play sealing effectiveness after bringing it about deformation by compressing sealing gasket, thus correlation zero can be reduced
The requirement on machining accuracy of part, simplify manufacturing process, can effectively reduce cost of goods manufactured, also reduce product later maintenance into
This, extends oil connection service life；
2nd, by using red copper pad as sealing gasket, because red copper material is softer, it can be deformed after stress extruding, i.e.,
Better seal effect can be achieved, while red copper pad can bear higher temperature and pressure, be not in because of HTHP
Cause the situation of seal failure.
