Description
Technical field
The utility model relates to a kind of helical bellows electricity consumption hot melt link.
Background technique
Along with people's is to the concern of environmental protection; In the municipal engineering pipeline network construction; Helical bellows is with characteristics such as its light weight, high tenacity, corrosion-resistant, anti-aging, environmental protection, in international, the domestic desirable substitution material that is just becoming conventional concrete pipe, cast iron tube, common plastics waste pipe.Safe and reliable connection is the key point that guarantees the permanently effective use of helical bellows.Its joint style adopts pyrocondensation joint at present, and after the pyrocondensation joint heating, effect at high temperature down; Utilize the function of its contraction to coat pipeline, play the effect of sealing, but the intensity of pyrocondensation joint is low; A little less than the counter-bending power; Gap between joint and the tubing is difficult to accurate control, and the seepage phenomenon of join domain can take place after the installation, destroys quality of connection.In pipeline lifting, backfilling process, the joint damage that very easily fractures.
The model utility content
The utility model technical problem to be solved is: provide a kind of simple in structure, easy to operate, the helical bellows electricity consumption hot melt link that join strength is high.
The technological scheme that the utility model technical solution problem adopts is: helical bellows electricity consumption hot melt link, comprise the helical bellows that port docks, and also comprise matrix, matrix is wrapped in the butt joint joint, and said matrix two ends are provided with electric installation.
Further be, said matrix comprises skin, internal layer, and be embedded in the electric heating fuse net between skin and the internal layer.
Further be that said electric heating fuse net is a metallic material.
Because electric heating fuse net is embedded between skin and the internal layer, the position is more fixing, in operating process, the danger and the situation of local superheating that the heating wire net moves can not take place, can effectively improve the quality after the connection, the reliability height.
Further be, said electric installation is to be connected two online wiring terminals of electric heating fuse, and this wiring terminal and is connected energising with electric hot-melting machine between electric heating fuse net and internal layer.
The beneficial effect of the utility model is: the utility model is used for the connection between the helical bellows.Electric thermal smelting belt is wrapped on the pipeline, and energising makes the outer surface and the interior melting layer of the molten connecting band of electric heating of pipeline, engages, thereby reaches purpose of connecting.Advantages such as this model utility has simple in structure, and mechanical strength is high, and counter-bending ability is strong.Be adapted at promoting the use in the connection of helical bellows.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 applies to the schematic cross-section after bellows connects for the utility model.
Mark among the figure: matrix 1, skin 2, internal layer 3, electric heating fuse net 4, wiring terminal 5, helical bellows 6.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1, the utility model relates to a kind of helical bellows electricity consumption hot melt link, comprises the helical bellows 6 of port butt joint, also comprises matrix 1, and matrix 1 is wrapped in pipeline butt joint joint, and said matrix 1 two ends are provided with electric installation.
Said matrix comprises skin 2, internal layer 3, and be embedded in the electric heating fuse net 4 between skin 2 and the internal layer 3.
Because the molten link of this electric heating is used for helical bellows 6; Its skin 2 is and the close material of helical bellows 6 cladding materials like this, can make molten link of electric heating and helical bellows 6 outward appearances clean and tidy; Working life is close; Generally select high-density polyethylene material for use, its internal layer 3 is used to melt back connecting tube 6, and internal layer 3 materials can melt after meeting high temperature fast.
This matrix 1 is a sheet structure, and its width and length are all adjustable, so the molten link of this electric heating can be used for the pipeline of various different models.Since electric heating fuse net 4 be embedded in outer 2 with internal layer 3 between, the position is more fixing, in operating process, the danger that electric heating fuse net 4 moves and the situation of local superheating can not take place, can effectively improve the quality after the connection, the reliability height.
Because electric heating fuse net 4 needs could generate heat after the conduction, utilize its conduction back heating that matrix 1 internal layer 3 and helical bellows 6 outer walls are melted and link together, therefore, said electric heating fuse net 4 is made up of metallic material.
Said electric installation is two wiring terminals 5 that are connected on the electric heating fuse net 4, and this wiring terminal 5 and is connected energising with electric hot-melting machine between electric heating fuse net 4 and internal layer 3.
After fixing the molten link of electric heating, wiring terminal is connected 5 receive on the electric hot-melting machine, open electric hot-melting machine, electric heating fuse net 4 generates heat under the effect of electric current, fusing matrix 1 internal layer 3 and helical bellows 6 outer walls, thus reach purpose of connecting.
The workflow that the utility model is used for helical bellows 6 connections is:
The helical bellows 6 that needs are connected lies in a horizontal plane in the position of being convenient to process, port butt joint, and welding.Removing is bonded at earth, moisture and other foreign material on the joint area pipe surface.The molten connecting band of electric heating is wrapped in the trough of two bellows joints, the trough of Electric thermal smelting belt and helical bellows 6 is fitted tightly.The width of the molten connecting band of electric heating is two distances between the trough.The output line and the wiring terminal 5 of hot-melting machine are joined, and setting starts hot-melting machine after heating time, makes helical bellows 6 outer surfaces and matrix 1 internal layer 3 melt, engage, thereby reaches purpose of connecting.After fusion process is accomplished, turn off power supply, wait for that the molten connecting band of electric heating fully cools off, accomplish to connect.
