Abstract
The utility model discloses an electric hot melting tape. The electric hot melting tape comprises a resistance wire net and a pair of electrode terminals connected with the resistance wire net, wherein a pair of parallel corresponding L-shaped flow guide wires are arranged at one end, far away from the electrode terminal, of the resistance wire net; and the L-shaped flow guide wires are flow guide copper wires. Compared with the prior art, the electric hot melting tape has the benefits that the flow guide wires are arranged in a corner cold region, so that the current blind region is eliminated completely when the traditional electric hot melting tape is welded, each part of the resistance wire emits heat uniformly, each part of the electric hot melting tape is heated uniformly and welded when the electric hot melting tape is welded, the welding time and the welding current are reduced, the welding strength is guaranteed, and the connecting sealing property is also guaranteed.
Description
Technical field
The utility model relates to the pipe joint technical field, particularly a kind of Electric thermal smelting belt.
Background technique
High density polyethylene (HDPE) (HDPE) entwining tube is that a kind of materials are economized, rigidity is high, the good tubing of sheathed.But entwining tube has high-impact, high measuring body characteristic than the common tube material-saving 40% of same specification with intensity, develops very fast.In states such as America and Europe, the HDPE entwining tube, quite replaced steel pipe, cast iron tube, cement pipe, asbestos pipe and common plastics tube in the scope, be widely used as waste pipe, sewage pipe, underground cable pipe, agricultural drainage and irrigation pipe.
That the connecting means of Electric thermal smelting belt formula has is easy for installation, connect advantages such as reliable, cheap, is the main connecting means of present HDPE entwining tube.The general structure such as the figure one of now commercially available Electric thermal smelting belt find out that from figure one Electric thermal smelting belt is on plastics (PE) sheet material, to press the high heating resistance wire net of one deck, respectively draws a wiring from the resistance screen of sheet material one end and uses electrode terminal.During welding; The HDPE entwining tube two-port that connects need with Electric thermal smelting belt coats and tightens up, and connects Ac from electrode terminal, and high heating resistance wire produces a large amount of heats; Making pipe and the plate on resistance wire both sides set up molecule penetrates each other; Each other tangle, form reliable intermolecular interaction, thereby make Electric thermal smelting belt and HDPE entwining tube fuse (like figure two).This shows that the heating value of resistance screen and uniformity are the keys of Electric thermal smelting belt welding quality quality, still; There is the electric current blind area in the traditional electrical hot melt belt when connecing, like figure three current distributing figures, two corner no currents in Electric thermal smelting belt overlap joint position pass through; This not heating of district's resistance wire; Plastics do not reach the hot melt state, can't connect (cold-zone, figure one yl moiety turning) by hot melt, directly influence whole Electric thermal smelting belt weld strength and sealability.Improve plate property (reduction fusing point), can reduce cold-zone, turning area, but can reduce weld strength greatly.
The model utility content
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of can eliminate the electric current blind area, reduces the cold Electric thermal smelting belt that removes area in turning.
The technological scheme of the utility model is: a kind of Electric thermal smelting belt, comprise resistance screen, a pair of electrode terminal that links to each other with resistance screen, and the end away from electrode terminal on resistance screen is provided with corresponding " L " type channelizing line of pair of parallel.
Described " L " type channelizing line is the water conservancy diversion copper cash.
Compared with prior art; The beneficial effect of the utility model is: electric current blind area when connecing through being increased in cold-zone, turning increase channelizing line, thoroughly eliminating the traditional electrical hot melt belt evenly generates heat the resistance wire each several part; The each several part welding that evenly heats up when making the Electric thermal smelting belt electric-fusion; Reduce weld interval and welding current, both guaranteed heat seal strength, guarantee to connect sealability again.
Description of drawings

Fig. 2 is existing Electric thermal smelting belt CURRENT DISTRIBUTION schematic representation.
Fig. 3 is the utility model structural representation.
Fig. 4 is the CURRENT DISTRIBUTION schematic representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 3; A kind of Electric thermal smelting belt; Comprise resistance screen 1, first electrode terminal 21 that links to each other with resistance screen and second electrode terminal 22, on resistance screen, be provided with first " L " type water conservancy diversion copper cash 31 and second " L " type water conservancy diversion copper cash 32 of parallel correspondence away from an end of first electrode terminal 21 and second electrode terminal 22.
As shown in Figure 4, during the utility model work, the CURRENT DISTRIBUTION on the Electric thermal smelting belt is even; Eliminated the deficiency that CURRENT DISTRIBUTION in the existing technology is inhomogeneous, have a cold-zone, turning; Adopt all the surface of contact heating soaking of new route mode Electric thermal smelting belt and entwining tube, firm welding does not have the welding blind area.Simultaneously, electric smelting time and size of current all decrease.
Claims (2)
1. an Electric thermal smelting belt comprises resistance screen, a pair of electrode terminal that links to each other with resistance screen, it is characterized in that: the end away from electrode terminal on resistance screen is provided with corresponding " L " type channelizing line of pair of parallel.
2. Electric thermal smelting belt according to claim 1 is characterized in that: described " L " type channelizing line is the water conservancy diversion copper cash.
