Description
Technical field:
The utility model relates to a kind of metal and plastic composite pipe, is particularly applied to employing plastically welding that thin-wall metal is connected with plastic composite pipe and the pipe fitting of clip connected.
Background technique:
Existing metal and plastic composite pipe mainly refer to, its pipeline lining is that plastic outer layer is metal (being generally steel), and within the plastics of its internal layer are hidden in outer layer metal completely, skin is smooth metal tube.The connecting means of composite pipe is at present more, and modal have: screw connected, this Placement mainly relies on outer layer metal to be threaded, and internal layer is without connection, has the poor problem of antiseptic property; Clip connected, this Placement is mainly made groove by outer layer metal, and joint utilizes groove clamping hoop, and crimping connects together pipe fitting with socket joint.The pipe end of joint is useless in the metal ring connecting, the also plastic hoop for sealing not, and pipeline is failed to realize metal and is distinguished and be connected simultaneously with plastics, exist the join strength of pipeline not high, Sealing adopts rubber or other filler more, can not realize the composite joint of multiple tube, and antiseptic power is low.
Summary of the invention:
Technical problem to be solved in the utility model is: how to solve metal be connected with plastic composite pipe in join strength poor, the problem that joint antiseptic power is low.
The technological scheme that the utility model adopts is: a kind of metal and plastic composite pipe connection set, comprise the first connecting end, the second connecting end, bolt, electric smelting sheet, upper metal clip, plastic ring, lower metal clip, in described upper metal clip, there is wire perforation, described the first connecting end and the second connecting end have metal connecting ring, described metal connecting ring is inclined-plane with the surface of contact of upper and lower metal clip, described electric smelting sheet is comprised of plastics and electric heating wire, electric heating wire coils in plastics, electric heating wire is all surrounded by plastics, electric heating wire is drawn from radial direction, electric smelting sheet is toroidal.
The utility model is in connection procedure, first connecting end that first will connect and the alignment of the second connecting end, the circular electric fuse piece identical with this composite pipe diameter is clipped between the first connecting end and the second connecting end, then utilize upper and lower metal clip that the alignment of the metal connecting ring of the first connecting end and the second connecting end is held tightly, the wire of electric smelting sheet is passed from the wire of upper metal clip simultaneously, then utilize bolt that upper and lower metal clip is linked together, and make connection pipe fitting have certain pretightening force by bolt, subsequently the wire of electric smelting sheet is connected to and on power source special, is energized to the stipulated time, inner plastic place has connected, so far, pipe fitting successful connection.
The beneficial effects of the utility model are: the utility model can make thin-wall metal and inner plastic all couple together, and can guarantee the join strength of pipe fitting, can guarantee again the antiseptic effect of joint, simple to operate, at the bottom of labor intensity, meet growing work requirements.

Embodiment
Embodiment 1
Metal is connected with pipeline with plastic composite pipe pipeline to adopt and connects as the equal diameter pipe of Fig. 1.Pipe fitting connected element is comprised of upper and lower metal clip 6,10, electric smelting sheet 3, bolt 9.During connection, adjust pipeline location, make inner plastic 11 corresponding good and sound, electric smelting sheet 3 is placed in to the first connecting end 1 and the second connecting end 2 centres, upper and lower metal clip 6 and 10 is enclosed within to the second connecting end metal connecting ring 7 and second connecting end metal connecting ring 8 outsides of pipe fitting joint, and the static wire of electric smelting sheet 3 is passed to the wire perforation 4 of upper metal clip 6, tighten the bolt 9 of metal clip, metal shell 8 is coupled together, as shown in Figure 4, electric smelting sheet is made by inlaying electric heating wire 14 in the middle of the plastics 13 with the identical material of pipe fitting inner plastic, subsequently the electric heating wire of electric smelting sheet 3 14 is connected to and on power source special, is energized to the stipulated time, inner plastic place has connected, so far, pipe fitting successful connection.
Embodiment 2
The bending part of metal and plastic composite pipe pipeline adopts as the elbow of Fig. 2 is connected, and connecting means is same as described above, and difference is the first used connecting end 1, the second connecting end 2, metal clip 6,10 etc. is all crooked up and down.
Embodiment 3
The threeway branch of metal and plastic composite pipe pipeline adopts and is connected as the threeway of Fig. 3, connecting means is same as described above, difference is that the first connecting end is threeway, and the second connecting end is straight or curved, and other corresponding component adjusts accordingly according to shape.
