Abstract

A copper plated internal thread straight joint comprises a plastic pipe a (1) with a larger external diameter and a plastic pipe b (2) with a smaller external diameter; the plastic pipe a (1) and the plastic pipe b (2) are formed through co-extrusion injection molding at one time; the inner part of the plastic pipe a (1) is communicated with the inner part of the plastic pipe b (2); a metal layer (3) with the copper-plated internal thread is inlaid on the inner wall of the plastic pipe a (1) to form a whole; a limiting step a (6) is arranged at the inner end of the internal thread of the plastic pipe a (1); a limiting step b (5) is arranged on the inner wall of the plastic pipe b (2) in a position close to the communicated part; and a plurality of anti-skid sheets (4) axially parallel to the straight joint with the copper plated internal thread are arranged on the surfaces of the ends of the plastic pipe a (1). The utility model has the advantages of reasonable structure, convenient connection, favorable sealing performance, and no leakage.

Description

Edge copper internal thread straight joint
Technical field
The utility model relates to a kind of pipeline straight joint, especially inlays copper internal thread straight joint.
Background technique
Use the common pipe straight joint to connect at present in the pipeline, Placements such as FERRULETYPE, compression type, clamp-press type, clamp band type are arranged, connect by these modes, joint barotolerance and heat-resisting quantity are relatively poor, influence the normal use of pipeline, the joint is prone to the seepage phenomenon.The Placement of metal pipe has enlarging, welding etc., and these Placement complicated operations are used inconvenient.
Summary of the invention
The purpose of this utility model promptly is to overcome the deficiencies in the prior art, edge copper internal thread straight joint easy for installation, high voltage bearing is provided, and edge copper internal thread is ductile, after edge copper internal thread straight joint spins by screw thread with outer tubing, the link position better tightness can prevent the seepage phenomenon.
The purpose of this utility model is achieved through the following technical solutions: edge copper internal thread straight joint, it is made up of external diameter bigger plastic tube a and the less plastic tube b of external diameter, plastic tube a and plastic tube b internal communication, plastic tube a inwall are embedded with the metal layer of band edge copper internal thread, constitute an integral body.Plastic tube a internal thread inner end is provided with limited step a, and plastic tube b inwall is provided with limited step b near connection place, and the cross cut end (of a beam) of plastic tube a is provided with the anti-slide plate of a plurality of and described edge copper internal thread straight joint parallel to an axis.Edge copper internal thread straight joint is screwed on other tubing by edge copper screw thread.
By top narration as can be seen, the utility model has following advantage: rational in infrastructure, easy to connect, favorable sealing property the seepage phenomenon can not occur.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Among the figure, 1-plastic tube a, 2-plastic tube b, the 3-metal layer, 4-prevents slide plate, 5-limited step b, 6-limited step a.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, edge copper internal thread straight joint is made up of external diameter bigger plastic tube a1 and the less plastic tube b2 of external diameter, plastic tube a1 and plastic tube b2 internal communication, plastic tube a1 and plastic tube b2 adopt a co-extrusion injection moulding to form, plastic tube a1 inwall is embedded with the metal layer 3 of band copper internal thread, plastic tube a1 internal thread inner end is provided with limited step a6, to guarantee no longer to continue the precession plastic tube after outer tubing connecting end arrives limited step a6, the b2 inwall is provided with limited step b5 near connection place, the access degree of depth of the outer tubing of restriction, it is best to make hot melt connect effect, the cross cut end (of a beam) of plastic tube a1 is provided with the anti-slide plate 4 of a plurality of and described edge copper internal thread straight joint parallel to an axis, and convenience spins with outer tubing.
