Abstract
The utility model discloses a petroleum casing joint, including connecting the body, it is inside sunken to connect the body middle part, connect this internal connecting axle of establishing, connecting axle both ends and this end of body of joint intercommunication, connect the vertical sealing ring that is equipped with in body middle part, the sealing ring imbeds the setting respectively at the connecting axle and on connecting the body, vertical installation has the axis in the sealing ring, axis top and bottom are all passed and are connected body upper surface and lower surface setting, transversely be equipped with the anti -corrosive filler layer between sealing ring and the axis, anti -corrosive filler fixes on the layer in the sealing ring reaches epaxially, this petroleum casing joint, reliable connection, good sealing effects are achieved, antiseptic effect still has, the life cycle has prolonged, anti -corrosion performance is strong, long string and petroleum casing pipe have been practiced thrift in a large number in the certain degree, can extensively be arranged in the oil development.
Description
Technical field
The utility model relates to a kind of joint, particularly a kind of petroleum sleeve joint.
Background technique
Existing petroleum sleeve joint position many employings surface antiseptisis technology, in severe Environmental Conditions, often will soon there is corrosion phenomenon in petroleum sleeve joint position, be easy to cause scrapping of petroleum pipeline, a large amount of economic loss is caused every year to enterprise, if do not make corresponding protective measures to it, also can continue to cause unnecessary economic loss, affect very serious.
Model utility content
The technical problems to be solved in the utility model is: overcome the problems referred to above, and provide a kind of and connect reliably, good sealing effect, also has antiseptic effect, extends the petroleum sleeve joint of life cycle.
To achieve these goals, the technical solution adopted in the utility model is such: petroleum sleeve joint of the present utility model, comprise joint body, cave inward in the middle part of joint body, coupling shaft is established in joint body, coupling shaft two ends are communicated with joint body end, vertically seal ring is provided with in the middle part of joint body, seal ring embeds respectively and is arranged on coupling shaft and joint body, vertically axis is installed in seal ring, axis top and bottom are all arranged through joint body upper surface and lower surface, laterally anticorrosive packing layer is provided with between seal ring and axis, anticorrosive packing layer is fixed on seal ring and axis.
Further, as a kind of concrete structural type, anticorrosive packing layer cross section described in the utility model adopts netted cross section structure.
Further, as a kind of concrete structural type, anticorrosive packing layer described in the utility model is connected with adopting thermoplasticity between seal ring.
Further, as a kind of concrete structural type, the built-in nylon nano anti-corrosion structure layers of anticorrosive packing layer described in the utility model.
Further, as a kind of concrete structural type, the middle part of seal ring described in the utility model is cylinder barrel shaped, uniformly on the middle part inner circle wall of seal ring arranges along its axial arranged groove.
Compared with prior art, the utility model has the advantage of: this petroleum sleeve joint, connect reliable, good sealing effect, also has antiseptic effect, extends life cycle, corrosion resistance is strong, to a certain degree substantial saving in long string and petroleum casing pipe, can be widely used in petroleum production.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure: 1. joint body; 2. coupling shaft; 3. seal ring; 4. axis; 5. anticorrosive packing layer.
Embodiment
Be described in further detail the utility model by reference to the accompanying drawings now, these accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The preferred embodiment of the utility model petroleum sleeve joint as shown in Figure 1, comprise joint body 1, cave inward in the middle part of joint body 1, coupling shaft 2 is established in joint body 1, coupling shaft 2 two ends are communicated with joint body 1 end, seal ring 3 is vertically provided with in the middle part of joint body 1, seal ring 3 embeds respectively and is arranged on connection 2 axle and joint body 1, in seal ring 3, axis 4 is vertically installed, axis 4 top and bottom are all arranged through joint body 1 upper surface and lower surface, laterally anticorrosive packing layer 5 is provided with between seal ring 3 and axis 4, anticorrosive packing layer 5 is fixed on seal ring 3 and axis 4, described anticorrosive packing layer 5 cross section adopts netted cross section structure, described anticorrosive packing layer 5 adopts thermoplasticity to be connected with between seal ring 3, the built-in nylon nano anti-corrosion structure layers of described anticorrosive packing layer 5, the middle part of described seal ring 3 is cylinder barrel shaped, uniformly on the middle part inner circle wall of seal ring 3 arrange along its axial arranged groove.
Petroleum sleeve joint of the present utility model, connect reliable, good sealing effect, also there is antiseptic effect, extend life cycle, corrosion resistance is strong, to a certain degree substantial saving in long string and petroleum casing pipe, can be widely used in petroleum production, described anticorrosive packing layer 5 cross section adopts netted cross section structure, and described anticorrosive packing layer 5 adopts thermoplasticity to be connected with between seal ring 3, the built-in nylon nano anti-corrosion structure layers of described anticorrosive packing layer 5, better can not only improve antiseptic property, also greatly strengthen the service life of anticorrosive packing layer; The middle part of described seal ring 3 is cylinder barrel shaped, uniformly on the middle part inner circle wall of seal ring 3 arranges along its axial arranged groove, and sealing effect is better, can better avoid occurring Seepage.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff completely can in the scope not departing from this model utility technological thought, carry out various change and amendment, the technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
