Abstract
The utility model relates to a connecting element between tubes, in particular to a multi-angle electric smelting sleeve for connecting the tubes when the PE tubes are used in fuel gas and water supply in a non-excavation mode. The multi-angle electric smelting sleeve is characterized by comprising two sleeve bodies, and a corrugated tube is connected between the two sleeve bodies. According to the multi-angle electric smelting sleeve, the two PE tubes at different angles can be connected, the internal stress can be effectively relieved, construction can be easily and conveniently carried out, and the technical problems that in the prior art, PE tubes at different angles are high in connecting difficulty, the internal stress cannot be effectively relieved and great difficulties are brought to construction are solved.
Description
Technical field
The utility model relates to the connector element of pipeline and pipeline, relates in particular to a kind of PE pipeline when combustion gas is adopted non-excavation with water supply, the multi-angle electric melting sleeve that pipeline is connected with the electric smelting of pipeline in the different amount situation.
Background technique
Electric melting sleeve is indispensable a kind of joint during steel-skeleton plastic composite pipe connects, and unidirectional pipeline firmly is welded together.Patent document about electric melting sleeve also has, such as Chinese patent: " a kind of electric melting sleeve and steel skeleton plastic clad pipe (CN202402867U) ", comprise pure plastic electrofusion sleeve, pure plastic electrofusion sleeve has the metal steel bushing outward.This electric melting sleeve is mainly to increase outside the layer of metal steel bushing in order to strengthen electric melting sleeve in the pressure-bearing situation, to design.But can only be used for connect two pipelines on same axis, not propose any solution for the connection of different amount pipeline.In recent years along with the industry of urban road Infrastructure with perfect.Road excavation is examined becomes combustion gas, how the outstanding difficult problem of the relevant units such as water supply solves the difficult problem of puzzlement, and one of its method is to adopt the push pipe mode of non-excavation, due to the narrow limitation of push pipe distance, certainly exist pipeline and pipeline at the connectivity problem at unearthed point place.Pipeline connects because angle is different, and traditional Placement difficulty is large, and internal stress can not effectively be eliminated, and therefore brings difficulty to construction, gives putting into operation and hide some dangers in the future.
Summary of the invention
It is a kind of when non-excavation operation that the utility model provides, and can connect the PE pipeline of two different amount, and the internal stress that produces when effectively eliminating the push pipe operation, the multi-angle electric melting sleeve simply and easily of constructing; Solved the different amount PE pipe connection difficulty that exists in the prior art large, internal stress can not effectively be eliminated, and brings the technical problem of difficulty to construction.
Above-mentioned technical problem of the present utility model solves by following technical proposals: a kind of multi-angle electric melting sleeve is characterized in that: comprise two sleeve body, be connected with bellows between two sleeve body.Utilize pliability and the plasticity of bellows, can realize the connection between the different amount pipeline, the internal stress that produces when the stretchability of bellows can absorb push pipe simultaneously, thus improve the convenience of construction.
As preferably, described sleeve body and bellows-welding place are provided with the anti-deforming cover, and the anti-deforming cover is positioned on the inwall of sleeve body.In both joints, the anti-deforming cover is installed, can be effectively prevented from extending the sleeve body of electric melting sleeve and the distortion that bellows produces when welding, guarantee the close contact of injection mould and sleeve body.
As more preferably, described anti-deforming cover is fixed on sleeve lining by spot welding.Fix by the spot welding mode, simple in structure, be connected firmly.
As preferably, described sleeve body is Stainless Steel Tube, and described bellows is many ripples corrugated stainless steel tubing.The Stainless Steel Tube load performance is good, simultaneously convenient welding.Sleeve body and bellows are all stainless steel material, and overall performance is stable, when moulding transition as the steel of gap bridge steel pipe and PE pipe, can effectively absorb the axial internal stress that steel pipe expands with heat and contract with cold and produces.
As preferably, the wave mode of described bellows is S shape.Decrement is large, and resiliently deformable is good.
As preferably, offer 12 slotted holes and twice dovetail groove on the circumference of described sleeve body.Electric melting sleeve is when injection moulding, in order to ensure the integrity of Stainless Steel Tube and electric melting sleeve, offer 12 slotted holes on the circumference of Stainless Steel Tube, help the inside and outside perforation of plastics, the dovetail groove of offering on this external Stainless Steel Tube cylindrical, after making plastics inject, more strengthened pull resistance, the integrity of electric melting sleeve.
Therefore, a kind of multi-angle electric melting sleeve of the present utility model possesses following advantage: the corrugated stainless steel tubing of multi-angle electric melting sleeve has the reelability of various angles, stretchability, the internal stress that produces in the time of can absorbing push pipe; While multi-angle electric melting sleeve can be used as the steel of gap bridge steel pipe and PE pipe and moulds transition, absorbs the axial internal stress that steel pipe expands with heat and contract with cold and produces.
Description of drawings
Fig. 1 is the schematic diagram of a kind of multi-angle electric melting sleeve of the present utility model.
Fig. 2 is use phase diagram of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technological scheme of model utility is described in further detail.
Embodiment:
As shown in Figure 1, a kind of multi-angle electric melting sleeve comprises columniform sleeve body 1, and sleeve body 1 adopts stainless steel material one-body molded.A side in sleeve body 1 is connected with bellows 2, and bellows 2 is also to adopt stainless steel material to make.The wave mode of bellows 2 is S shape.The anti-deforming cover 3 of annular is arranged in bellows 2 and sleeve body 1 connecting part, and anti-deforming cover 3 is positioned on the inwall of sleeve body 1, is fixed on by spot welding on the inwall of sleeve body 1.Offer slotted hole 4 and two dovetail grooves 5 of connecting working of plastics on sleeve body 1.
As shown in Figure 2, the installation of multi-angle electric melting sleeve; In the working pit of push pipe unearthed point, block PE pipe redundance by the effective length of multi-angle electric melting sleeve, code requirement by the electric melting sleeve welding scrapes off oxide layer, multi-angle electric melting sleeve one side is inserted intended PE pipe joint 6 places to be welded, implement welding, after cooling inspection is errorless, the electric melting sleeve joint of opposite side is aimed at after compress bellows intended PE pipe joint to be connected, release pressure, connection puts in place, is the internal stress that prevents from producing because of angle, and available crowbar is auxiliary to be adjusted, errorless rear welding is until cooling.
