Embodiment Construction

[0021] Such as figure 2 As shown, the plastic electric melting belt 4 reinforced by wire mesh or metal orifice plate of the present invention includes a thermoplastic strip 5, one side of the plastic strip 5 is press-fitted with a conductive metal mesh 6, and the conductive metal mesh 6 is on the The two ends in the length direction are connected with the conductive metal mesh 6 to connect the wire electrodes 7, and the plastic strip 5 is compounded with at least one layer of reinforced wire mesh or metal hole plate 8. The length of conductive metal net 6 is identical with the length of plastic strip 5, and the edge of longitudinal conductive metal net 6 is flush with the edge of plastic strip 5, and the width of conductive metal net 6 is slightly less than the width of plastic strip 5, and the width Each edge of the conductive metal mesh 6 is at an equal distance from the corresponding edge of the plastic strip 5 in the direction. Like this, can prevent the molten plastic f...

Abstract

The invention relates to a screen mesh or metal hole plate-reinforced plastic electric hot melting belt used for connecting a plastic pipeline. The screen mesh or metal hole plate-reinforced plastic electric hot melting belt comprises a thermoplastic plastic plate belt, wherein a conductive metal net is pressed and embedded on a plate surface at one side of the plastic plate belt; two ends of the metal net in a length direction are provided with outgoing wire electrodes connected with the metal net; and at least one layer of reinforced screen mesh or metal hole plate is compounded in the plastic plate belt. A connecting structure for connecting the plastic pipeline with the electric hot melting belt comprises a coating electric hot melting belt, filling solders and a lapping electric hot melting belt, wherein the coating electric hot melting belt is coated and fusion-welded on the outer wall surfaces of two connected pipe end connecting areas in a manner of two-end butting or is adhered and fusion-welded on the inner wall surfaces of two connected pipe end connecting areas, and a gap suitable for welding is arranged at an abutting joint; the filling solders are used for welding and filling the gap of the abutting joint of the coating electric hot melting belt; and the lapping electric hot melting belt is used for fusion-welding a surface area of the abutting joint of the coating electric hot melting belt. A connecting method for connecting the plastic pipeline is comprised in the invention.

Description

technical field [0001] The invention relates to an electric heating fusing belt, in particular to a plastic electric heating fusing belt reinforced by a wire mesh or a metal orifice plate. The invention also relates to a connection structure and a connection method for connecting plastic pipes with the electric heating fusing tape. Background technique [0002] The existing ordinary plastic electric heating belt products based on the known technology are composed of thermoplastic strips and a conductive metal mesh pressed and inlaid on one surface of the strips, which are widely used in the connection of large-diameter pressureless thermoplastic drainage pipes . Ordinary plastic electric heating belts are made of pure plastic, and their tensile strength is low, so they can only be used in drainage pipes that only bear external pressure (no tensile stress load). When in use, it is coated on the outer wall surface of the connected pipe end, or closely attached to the inner w...
