The connecting end of each female connector is provided with a taper end face, the connecting end of each male connector is provided with a taper sleeve opening matched with the corresponding taper end face, a liner layer is arranged on the inner wall of the composite pipe, and the flanges of the male connectors and the female connectors are fixedly connected with slips, and the outer surface of each slip is provided with a taper sleeve in a sleeved mode. The self-tightening connector connecting structure of the composite pipe slip taper sleeve is simple in structure, reasonable in design, capable of achieving self tightening, good in sealing performance, not prone to leakage, resistant to bending and high pressure and simple in construction.
Description
Technical field
The utility model relates to a kind of pipe connecting structure, is specifically related to a kind of composite pipe slips tapered sleeve self-tightening joint connecting structure.
Background technique
At present, at present, on oil field tap the latent power produce in application note polymerizing technology, but high pressure injection of polymer severe corrosive and abrasion make in steel pipe anticorrosive coat by quick-wearing very, corrode very soon, working life is short, has increased cost.Use now composite pipe to solve the problems referred to above, but the connection of composite pipe jointing generally adopts the basic Connecting format such as flange plate connection, welding, these Placements are comparatively complicated.Have the structure that adopts slips to connect, but this Placement is not counter-bending, easily causes leakage yet, and not high pressure resistant, and impact is promoted the use of.
Summary of the invention
The purpose of this utility model is exactly the defect existing for prior art, provides a kind of simple in structure, reasonable in design, can realize self-tightening, and good airproof performance is difficult for revealing, counter-bending, high pressure resistant, the simple composite pipe slips tapered sleeve self-tightening joint connecting structure of constructing.
Its technological scheme is: composite pipe slips tapered sleeve self-tightening joint connecting structure, metal tube one end that described composite pipe joins is between two the tool joint pin with chimb, another connecting end is the female joint with chimb, the connecting end of described female joint is provided with tapered end face, the connecting end of described tool joint pin is provided with the taper running-on suitable with tapered end face, the inwall of described composite pipe is provided with inside liner, and the chimb place of described tool joint pin and female joint is fixedly connected with slips, and described slips outer surface is arranged with tapered sleeve.
Described tapered end face is stepped cone, described stepped cone comprises that cone angle is the first cone, the cylindrical body being connected with the first cone rounding off and second cone being connected with cylindrical body rounding off of 10 °～70 °, and the cone angle of described the second cone is 15 °～90 °.
Described tapered end face is curved surface cone, and described curved surface cone is parabola surface of revolution.
The chimb outside of described tool joint pin and female joint is provided with first conical surface suitable with two inner side card access surfaces of slips, and the cone angle of described first conical surface is Self-locking angle ± 3 °.
The internal surface of described tapered sleeve has with slips outer surface second conical surface matching, and the cone angle of described second conical surface is 4 °～Self-locking angle-2 °.
The utility model compared with prior art, has the following advantages: simple in structure, reasonable in design, can realize self-tightening, and good airproof performance, is difficult for revealing, and counter-bending, high pressure resistant, construction is simple.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment one structural representation;
Fig. 2 is the utility model embodiment two structural representation.
Embodiment
Embodiment one:
With reference to Fig. 1, composite pipe slips tapered sleeve self-tightening joint connecting structure, metal tube one end that described composite pipe joins is between two the tool joint pin 1 with chimb, another connecting end is the female joint 2 with chimb, the connecting end of described female joint 2 is provided with tapered end face 3, the connecting end of described tool joint pin 1 is provided with the taper running-on 4 suitable with tapered end face 3, the inwall of described composite pipe is provided with inside liner 5, described tool joint pin 1 and female joint 2 are fixedly connected with slips 7 by chimb 6, and described slips 7 outer surfaces are arranged with tapered sleeve 8.
Described tapered end face 3 is stepped cone, described stepped cone comprises that cone angle is the first cone 13, the cylindrical body 14 being connected with the first cone 13 rounding ofves and second cone 15 being connected with cylindrical body 14 rounding ofves of 10 °～70 °, and the cone angle of described the second cone 15 is 15 °～90 °.
During connection, inside liner 5 is penetrated, docking tool joint pin 1 and female joint 2, be connected to chimb 6 places by two semicircle slips 7, and be inserted in tapered sleeve 8, and outer painting is anticorrosion, constructs simple and reliable.
During use, under interior pressure effect, make inside liner 5 elastic expansions, the surface of the first cone 13, cylindrical body 14 and second cone 15 of compressing tool joint pin 1 is pressed on the corresponding internal conical surface of female joint 2 it, play a part to support inside liner 5, counter-bending ability is strong, and high pressure resistant; When tubular axle combined, during to resiliently deformable, the conical surface place of the first cone 13 there will be little annular space, and inside liner 5 is out of shape and is compensated under pressure, in case stopping leak reveals, and cylindrical body 14 and the second cone 15 places fit tightly, good sealing effect.This conical surface self-tightening sealing structure, can prevent from revealing, good sealing effect, and also high pressure resistant, counter-bending ability is strong.
Chimb 6 outsides of described tool joint pin 1 and female joint 2 are provided with first conical surface 9 suitable with two inner side card access surfaces of slips 7, and the cone angle of described first conical surface 9 is Self-locking angle ± 3 °.By this structure energy auto lock, prevent from use becoming flexible, high pressure resistant effective.
The internal surface of described tapered sleeve 8 has with slips 7 outer surfaces second conical surface 10 matching, and the cone angle of described second conical surface 10 is 4 °～Self-locking angle-2 °.Can play auto lock effect, prevent from use becoming flexible.
Embodiment two:
With reference to Fig. 2, other is basic identical with embodiment one, and difference is: described tapered end face 3 is curved surface cone 11, and described curved surface cone 11 is parabola surface of revolution.Enforcement parameter is: the surface of revolution of formed curve when the metal ball body class level speed of dishing out is 0.7cm/s～1.5 cm/s.During selection, can choose above-mentioned speed according to pressure size, the low choosing of pressure is worth greatly, and pressure is high selects little value.By curved surface cone, can realize good sealing effect, the strong effect of high pressure resistant, counter-bending ability.
The utility model is simple in structure, reasonable in design, can realize self-tightening, and good airproof performance is difficult for revealing, and counter-bending, high pressure resistant, construction is simple.
