Description
Technical field
This utility model relates to a kind of joint connection, particularly relates to a kind of joint connection for fiberglass plastics alloy composite pipe junction.
Background technology
The single well pipeline in oil extraction in oil field district is generally made up of fiberglass plastics alloy composite pipe, and these pipelines are usually due to pressure, variations in temperature or by high concentration H2The impact of S and corroded.Since 2013, the pipeline of oil production near Tarimhe River is concentrated and is occurred in that Problem of Failure, and oil spill disaster frequently occurs.Finding through statistics, in these oil spill disasters, the accident having about 44.82% is to be lost efficacy by the joint of fiberglass plastics alloy composite pipe to cause.
At present, the joint connection manner of fiberglass plastics alloy composite pipe is mainly gluing connection, i.e. socket joint defensive position pasty adhesive and connects, then is wound around compound glass silk.This connected mode is simple and convenient, low cost, time-consumingly few, and the most gluing being connected to is used widely when fiberglass plastics compo pipe connects.
But, there are the following problems to use existing bonding way to connect the method for fiberglass plastics alloy composite pipe, on the one hand joint joining during glue because firming agent is not enough or excess causes joint insufficient strength in gluing connection；On the other hand, the hydrogen sulfide that oil-producing region contains and and oil well in there is more heavy oil wells, in the case of long-term temperature and pressure change, the easy ageing failure of binding agent；Thus cause pipeline that leakage of oil frequently occurs, cause serious environmental problem and huge economic loss.
Accordingly, it would be desirable to design a kind of joint connection for fiberglass plastics alloy composite pipe, to guarantee not losing efficacy in glass reinforced plastic composite pipe joint, prevent crude oil leakage and environmental pollution.
Summary of the invention
For solving above-mentioned the problems of the prior art, this utility model provides a kind of joint connection.
For achieving the above object, the concrete technical scheme of joint connection of the present utility model is as follows:
A kind of joint connection, including: sealing gasket, cover outside the tube wall of multiple tube junction；Slips, is nested with on sealing gasket, and one end of slips is formed with surface and has externally threaded inclined-plane；Hollow sleeve, is nested with the outside at multiple tube, and the opening part of hollow sleeve end is formed with otch, and the surface of otch has the female thread that can mate with the external screw thread on inclined-plane；Rotary hollow sleeve can make slips crush seal pad to be fixed on multiple tube by sealing gasket.
Further, the surface of the otch being formed at hollow sleeve end is clinoplain, and has the slope identical with the inclined-plane of slips.
Further, between sealing gasket and multiple tube, tack coat it is provided with.
Further, grout layer it is filled with between hollow sleeve and multiple tube.
Joint connection of the present utility model can reduce the generation of pipeline thorn leakage, it is ensured that oil security produces, and prevents crude oil leakage and environmental pollution, thus significantly improves the safety of Crude Oil Transportation.
Accompanying drawing explanation
Fig. 1 is the structural representation according to joint connection of the present utility model.
Detailed description of the invention
In order to be best understood from the purpose of this utility model, structure and function, below in conjunction with the accompanying drawings, joint connection of the present utility model is described in further detail.
As it is shown in figure 1, joint connection of the present utility model includes that sealing gasket 2, sealing gasket 2 cover outside the tube wall of multiple tube 1 junction, sealing gasket can be used for sealing and protecting the junction of multiple tube；Sealing gasket 2 outer cover is equipped with slips 3, and slips 3 is preferably cone shape or the contract bodily form, and one end of slips 3 is formed with surface and has externally threaded inclined-plane 31；Above-mentioned joint connection also includes the hollow sleeve 4 being nested with outside multiple tube 1, the opening part of hollow sleeve 4 end is formed with otch 41, the surface of otch 41 has the female thread that can mate with the external screw thread on inclined-plane 31, and hollow sleeve 4 is threaded connection with slips 3.When rotary hollow sleeve 4, hollow sleeve 4 and slips 3 occur relative motion, slips 3 to be squeezed on multiple tube 1 by sealing gasket 2.
Further, the surface of the otch 41 being formed at hollow sleeve 4 end is clinoplain, and described clinoplain has the slope identical with the inclined-plane 31 of slips 3.
It addition, optionally sealing gasket 2 be provided with on the joint face of multiple tube 1 for increasing the tack coat (such as viscous resin layer) being connected effect.Additionally, can between hollow sleeve 4 and multiple tube 1 filling concrete pulp layer；Also can be in the outside joints cement pulp layer of multiple tube junction, preferably to protect the jointing of multiple tube so that it is not by temperature, pressure changes is affected, and extends the service life that pipeline is overall.
The specifically used process of joint connection of the present utility model is as follows, after processing utilizing existing method to be attached by two multiple tubes, cover according to sealing gasket 2 of the present utility model in the junction of two multiple tubes, then slips 3 and hollow sleeve 4 is added in the outside of sealing gasket 2, slips 3 and hollow sleeve 4 are threaded connection, then slips 3 tightened by rotary hollow sleeve 4 so that sealing gasket 2 is tightly squeezed in the junction of multiple tube.
Use joint connection of the present utility model, it is not necessary at multiple tube junction hands pasty adhesive so that multiple tube is closely coupled.
By specific embodiment, this utility model is further described above; although it is understood that; the most concrete description; should not be construed as the restriction to spirit and scope of the present utility model; the various amendments that above-described embodiment is made by one of ordinary skilled in the art after reading this specification, broadly fall into the scope that this utility model is protected.
