Abstract

The utility model discloses a connecting piece for plastic pipes and plastic compound pipes, including a pipe body (1) and a connecting jacket (2). The internal wall of the connecting jacket (2) is provided with an electric heating strip, through heating the electric heating strip, the two ends of the connecting piece are connected with the pipe body (1). The two ends of the internal hole of the connecting jacket (2) and the external axial end of the pipe body (1) are the conical structure with 0.3 degrees to 10 degrees taper. The utility model with convenient construction and operation, safe and reliable connection, superior sealing performance, can be widely applied in the electric melted connecting process of various plastic pipes, plastic compound pipes, polyethylene pipes and steel-skeleton reinforced plastic compound pipes.

Description

Plastic pipe and plastic composite pipe pipe connecting

One, technical field

The utility model relates to tubing and pipe joint, relates in particular to a kind of plastic pipe and steel skeleton plastic clad pipe pipe connecting.

Two, background technique

At present, the Placement of plastic tube, plastic composite pipe and steel-frame reinforced plastic composite pipe comprises that the hot melt butt joint is connected with electric smelting, and plastic tube is many with the mode of hot melt butt joint, and it is more that plastic composite pipe is then used the electric smelting Placement.The intensity of the docking point of hot melt docking mode is lower, and electric smelting connects this Placement and is difficult to grasp because of the matching gap of electrofusion connecting piece and tubing, therefore relatively difficulty is installed, the leakage phenomenon of connection part often takes place, and cause the electric heating wire of electrofusion connecting piece to damage easily, influenced quality of connection greatly.

Three, summary of the invention

The technical problems to be solved in the utility model is to overcome or avoid above-mentioned shortcoming of the prior art or deficiency, and a kind of easy construction that has is provided, and is simple to operate, plastic tube that join strength is high and plastic composite pipe link.

The technological scheme that the utility model will be dealt with problems is: the plastic tube and plastic composite pipe and the electrofusion connecting piece that comprise body and link, the two ends of its link link together the end of itself and body by the electric heating wire of heating equipment in link, the endoporus two ends of link and the external diameter end of body are cone structure, two taperings cooperatively interact, and its tapering is 0.3 °～10 °.The connection end of body is an external taper, and connecting sleeve endoporus two ends are inner taper, and its tapering is preferably 0.5 °～2.5 °.

The utility model compared with prior art has following advantage:

1. connection is convenient;

2. connection part intensity height is safe and reliable;

3. the gap when connecting between body and the link is even, and it is firm to connect, and does not have to leak good seal performance.

Four, description of drawings

Fig. 1 is the utility model example structure schematic representation.

Fig. 2 is the pipe structure schematic representation of the utility model Fig. 1.

Fig. 3 is the utility model body thickening design diagram.

Five, specific embodiments

Can implement the utility model well with reference to the accompanying drawings, be described in further detail below in conjunction with accompanying drawing:

As Fig. 1, the two ends of link 2 and body 1 link together, and the endoporus two ends of link 2 and the external diameter end of body 1 are cone structure, and its tapering is 0.5 °～1.5 ° (being expressed as 1 ° among the figure).

As shown in Figure 2, the end connection part of body 1 can be designed to structure thicker, and its thickness is 3～15mm (being 5mm among the figure)

Claims
