Abstract
For the deficiency overcoming existing petroleum sleeve joint to exist, this utility model provides a kind of petroleum sleeve joint, and this utility model includes joint body, connecting shaft, sealing ring, axis, anticorrosive packing layer, expansion joint, sealing lid；This petroleum sleeve joint can realize the mating operation of multiple interface, and connects reliable, and good sealing effect also has antiseptic effect, extends the use cycle.
Description
Technical field
This utility model relates to a kind of oil field device, a kind of mating operation that can realize multiple interface,
And connect reliable, and good sealing effect, also there is antiseptic effect, extend the petroleum sleeve joint in use cycle.
Background technology
Petroleum casing pipe is the important equipment of oil drilling, its main equipment also include drilling rod, basket and sleeve pipe, drill collar and
Slim hole drilling steel pipe etc..Domestic sleeve pipe is hot rolled with geological drilling steel or cold-drawn is made, grade of steel " geology " (DZ) table
Showing, conventional casing grade has DZ40, DZ55, DZ753 kind.Linking between sleeve pipe will use petroleum sleeve joint, existing
Petroleum sleeve joint position many employings surface antiseptisis technology, in severe use environment, petroleum sleeve joint position is often
Corrosion phenomenon will soon occur, it is easy to cause scrapping of petroleum pipeline, cause a large amount of economic loss to enterprise every year, if
It is not made corresponding safeguard procedures, also may proceed to cause unnecessary economic loss, affect extremely serious.
At present, known petroleum sleeve joint structure is to include joint body, connecting shaft, sealing ring, axis, anticorrosive packing
Layer.This petroleum sleeve joint can not carry out the linking between multiple sleeve pipe, and function is the most single, and practical limitation is stronger.
Summary of the invention
For the deficiency overcoming existing petroleum sleeve joint to exist, this utility model provides a kind of petroleum sleeve joint,
This petroleum sleeve joint can realize the mating operation of multiple interface, and connects reliable, and good sealing effect also has anticorrosion effect
Really, the use cycle is extended.
This utility model solves the technical scheme is that this utility model of its technical problem and includes joint body, company
Spindle, sealing ring, axis, anticorrosive packing layer, expansion joint, sealing lid.
Setting connecting shaft in joint body, connecting shaft two ends connect with joint body end, are vertically provided with in the middle part of joint body
Sealing ring, sealing ring is respectively embedded into and is arranged on connecting shaft and joint body, is vertically provided with axis, axis top in sealing ring
And bottom both passes through joint body upper surface and lower surface is arranged, and is transversely provided with anticorrosive packing layer between sealing ring and axis, anti-
Rotten packing layer is fixed on sealing ring and axis, and described sealing ring is horizontally installed with sealing lid, and the position sealing lid can be pacified
Dress expansion joint.
Thermoplasticity is used to be connected between anticorrosive packing layer and sealing ring.
Described anticorrosive packing layer built-in nylon nano anti-corrosion structure layers.
The beneficial effects of the utility model are, it is possible to achieve the mating operation of multiple interfaces, and connect reliable, sealing effectiveness
Good, also there is antiseptic effect, extend the use cycle.

Detailed description of the invention
At Fig. 1, in 2 illustrated embodiments, this utility model includes joint body 1, connecting shaft 2, sealing ring 3, axis 4, prevents
Rotten packing layer 5, expansion joint 6, sealing lid 7.
Setting connecting shaft 2 in joint body 1, connecting shaft 2 two ends connect with joint body 1 end, vertical in the middle part of joint body 1
Being provided with sealing ring 3, sealing ring 3 is respectively embedded into and is arranged on connection 2 axles and joint body 1, is vertically provided with axis in sealing ring 3
4, axis 4 top and bottom both pass through joint body 1 upper surface and lower surface is arranged, and are transversely provided with between sealing ring 3 and axis 4
Anticorrosive packing layer 5, anticorrosive packing layer 5 is fixed on sealing ring 3 and axis 4, and described sealing ring 3 is horizontally installed with sealing lid 7, close
Expansion joint 6 can be installed in the position of capping 7.
When being embodied as, when needing other joint, directly open sealing lid 7, expansion joint 6 docked up, it is achieved
The mating operation of multiple interfaces, states and uses thermoplasticity to be connected, in described anticorrosive packing layer 5 between anticorrosive packing layer 5 with sealing ring 3
Put nylon nano anti-corrosion structure layers, can not only preferably improve antiseptic property, also greatly strengthen the use year of anticorrosive packing layer
Limit.
As known by the technical knowledge, this utility model can be by other essence without departing from its spirit or the reality of essential feature
The scheme of executing realizes.
Embodiment disclosed above, for each side, is all merely illustrative, and is not only.All at this
All it is included in the utility model in the range of utility model or being equal to the change in the range of this utility model.
