Abstract
The utility model relates to a pipe connecting component structure, in particular to a pipe connecting component structure suitable for a shape memory alloy pipe connector. The pipe connecting component structure comprises a connected pipe, a rubber backing ring and a shape memory alloy pipe connector, wherein an external interface strengthening layer and an internal interface strengthening layer are arranged on the outer side of the connected pipe and the inner side of the shape memory alloy pipe connector respectively; the rubber backing ring and a heat-insulating layer are sequentially arranged on the outer part of the external interface strengthening layer; the shape memory alloy pipe connector of the internal interface strengthening layer is arranged on the inner side of the external interface strengthening layer. The pipe connecting component structure can effectively prevent primary battery reaction between shape memory alloy and a steel tube, so that not only the sealing performance between the connected pipe and the shape memory alloy pipe connector is improved, but also temperature deformation and a necessary ductility requirement during an earthquake can be met; the pipe connecting component structure has relatively good economic and social benefits.
Description
Technical field
The utility model relates to the structure of pipe joint, particularly relates to a kind of structure of the pipe joint that is applicable to marmem pipe road joint.
Background technique
At present, pipeline transport has become a kind of important Material Transportation form, is bringing into play irreplaceable important function in national economy.But, the leakage accident of the pipeline configuration causing due to a variety of causes often occurs, once pipeline configuration lost efficacy, huge economic loss and casualties will be brought, show after deliberation: the leakage accident of most of pipeline all occurs in the jointing of pipeline, main cause have following some: first, traditional oil transportation, feed channel interface adopts the method for welding more, welded structure has the superiority of itself, but also there are many welded structure malicious events, illustrate that this method itself exists defect, and be welded under naked light condition and work, just there is very large potential safety hazard in itself.Secondly, the etching problem of oil-gas pipeline facility is startling, and the corrosion of the pipeline weld joint of especially working under high temperature, high pressure is the most serious.Therefore want the generation of Avoids or reduces pipeline transport accident, not only normal maintenance is necessary, and for pipeline configuration significant points---pipe joint place will take necessary measure, adopt novel pipeline Placement to substitute original connecting means, can effectively avoid economic loss.
This functional material of marmem (SMA), because have shape memory effect (SME), can produce good driving force, and this drive performance can be used in the connection of pipeline.By the temperature of control connection part, make SMA produce certain phase transformation and cause circumferential deformation, thereby two-part pipeline to be connected is linked together effectively.Its FeMnSi be SMA because raw material are cheap, good mechanical property, hot working is easy, the hysteresis of phase transformation is wide and be subject to extensive concern.In petroleum pipeline and gas pipeline, use in recent years cheap iron-base marmem pipe joint to become a study hotspot.But existing iron-base marmem pipe road joint, does not all consider insulation and the sealing problem at interface between connected pipe and marmem pipe road joint and the anti-seismic performance of connected pipe.
Summary of the invention
The utility model is for the technical problem of above-mentioned existence, a kind of marmem-rubber pad ring combination pipe link is provided, the Ductility Requirement of necessity while preferably resolving temperature deformation or earthquake, effectively between prevention marmem and steel pipe, produce galvanic cell reflection simultaneously, reach the fastening force that can ensure to improve pipe coupling, can ensure again the structure of a kind of pipe joint that pipe interior anticorrosive coat is not destroyed.
The technological scheme of the utility model technical solution problem is to achieve these goals:
A structure for pipe joint, comprises connected pipe, rubber pad ring and marmem pipe joint, and its connected pipe outside and marmem pipe road joint inner side are respectively equipped with outer boundary strengthened layer and inner boundary strengthened layer; The outside of described outer boundary strengthened layer be also provided with successively rubber pad ring, thermal insulation layer with and inner side be provided with the marmem pipe joint of inner boundary strengthened layer.
Described outer boundary strengthened layer and inner boundary strengthened layer are epoxy glue layer.
Described thermal insulation layer is inorganic fibre mat.
The utility model compared with prior art has following advantages and effect: the utility model has added epoxy resin as interface enhancing layer owing to adopting in connected pipe outside and marmem pipe road joint inner side, and therefore the sealability of coupled pipeline, withstand voltage properties and anti-pulling performance are all improved preferably; Because can ensure adding of thermal insulation layer when marmem pipe joint is heated, the anticorrosive coat of pipe interior can be not destroyed again; The setting of rubber pad ring not only can prevent the galvanic cell reaction of two kinds of different metal materials, thereby reduce the rate of corrosion of metallic conduit, can improve the sealability between connected pipe and marmem pipe road joint simultaneously, again can satisfied temperature the Ductility Requirement of necessity when distortion and earthquake, there is good economic benefit and social benefit.

Fig. 2 is the cross section sectional structure schematic diagram of the utility model Fig. 1.
In figure: inner boundary strengthened layer 1, marmem pipe joint 2, thermal insulation layer 3, rubber pad ring 4, connected pipe 5, outer boundary strengthened layer 6.
Embodiment
Below in conjunction with specific embodiment, the utility model is further elaborated, but protection domain of the present utility model is not limited by specific embodiment, is as the criterion with claims.In addition, under the prerequisite without prejudice to technical solutions of the utility model, within any change that those of ordinary skill in the art that the utility model is done easily realize or change all will fall into claim scope of the present utility model.
Embodiment 1:
The structure of a kind of pipe joint as shown in Figure 1, 2, comprise connected pipe, rubber pad ring and marmem pipe joint, its connected pipe 5 outsides and marmem pipe road joint inner side are respectively equipped with outer boundary strengthened layer 6 and inner boundary strengthened layer 1; The outside of described outer boundary strengthened layer 6 be also provided with successively rubber pad ring 4, thermal insulation layer 3 with and inner side be provided with the marmem pipe joint 2 of inner boundary strengthened layer 1.Described outer boundary strengthened layer 6 and inner boundary strengthened layer 1 are epoxy glue layer, and described thermal insulation layer 3 is inorganic fibre mat.
When the utility model specifically uses:
First polished in connected pipe 5 surfaces, then coat epoxy glue layer in connected pipe 5 outsides and joint 2 inner sides, marmem pipe road, solidify rear formation outer boundary strengthened layer 6 and inner boundary strengthened layer 1; Then put prefabricated rubber pad ring 4 in outer boundary strengthened layer 6 outsides of connected pipe 5, the internal diameter of this rubber pad ring 4 is less than the external diameter of connected tube; At the thermal insulation layer of rubber pad ring 4 outside spraying inorfils; Outermost surface shape-memory pipe coupling 2 is inserted in to connected pipe 5 outsides; Finally heat in marmem pipe joint 5 outsides with heater dedicated, be incubated and take off heater after ten minutes, marmem pipe connects 2 because produce shape memory effect contraction deformation, thereby holds tightly, fixes and connect two steel pipes.
Complete the process of utilizing marmem-rubber pad ring combination pipe link to connect two pipelines.
The utility model is rational in infrastructure, is easy to processing, and work progress is simple, effective, practical simultaneously, is beneficial to and applies.
