Abstract
The utility model discloses a connection type pipe, which includes an internal connecting piece, a first metal-plastic composite pipe and a second metal-plastic composite pipe, wherein the outer part of the first part of the internal connecting piece is sleeved with the first metal-plastic composite pipe, the outer part of the second part of the internal connecting piece is sleeved with the second metal-plastic composite pipe, and the first metal-plastic composite pipe and the second metal-plastic composite pipe are welded and fixed mutually by cold welding flux. The connection type pipe has the technical effects of pressure resistance, oil resistance, corrosion resistance, high-temperature resistance, low cost and good sealing effect.
Description
Technical field
The utility model relates to a kind of link, particularly a kind of connected pipe fitting for composite metal-plastic pipe.
Background technique
Applying of present domestic composite metal-plastic pipe is growing, in use, there are some problems in connection for the metal composite pipe of large, medium caliber, because the common wall thickness of metal layer of composite pipe is thinner, the Placement that is not easy to the conventional pipe fittings such as tapping, electric welding realizes, if the increase metal layer thickness, its cost greatly increases.Some employings " electric-melting " connect, make the suffered axial force of pipeline only depend on the outer plastic layer connection part with, be difficult to adapt to the usage requirement of Intermediate High Pressure pipeline, and heat resistance is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of connected pipe fitting of good airproof performance.
A kind of connected pipe fitting of the present utility model comprises:
Built-in link;
Be inserted in the first composite metal-plastic pipe in described built-in link first portion outside; And
Be inserted in the second composite metal-plastic pipe in described built-in link second portion outside.
Preferably, described built-in link first portion be from the middle of the built-in link to the part of one end.
Preferably, described built-in link second portion is from the middle part to its other end of built-in link.
Preferentially, the metal layer of described the first composite metal-plastic pipe one end is inserted in built-in link first portion outside.
Preferably, the metal layer of described the second composite metal-plastic pipe one end is inserted at built-in link second portion outside.
With respect to above-mentioned prior art, the utility model can make greatly, the composite metal-plastic pipe of medium caliber be connected firmly and have withstand voltage, oil resistant, corrosion resistant, high temperature resistant, cost is low, the technique effect of good airproof performance.
Below in conjunction with accompanying drawing the utility model is elaborated.
Description of drawings
Fig. 1 is the structural representation of connected pipe fitting of the present utility model.
Embodiment
Fig. 1 has shown the structure of connected pipe fitting of the present utility model, and such as Fig. 1, connected pipe fitting of the present utility model comprises, built-in link 3 is inserted in the first composite metal-plastic pipe 1 in built-in link 3 first portion outsides; And be inserted in the second composite metal-plastic pipe 2 in built-in link 3 second portion outsides.
The first portion of built-in link 3 of the present utility model is from the middle part to the one end of built-in link.
The second portion of built-in link 3 of the present utility model is from the middle part to its other end of built-in link.
Specifically, the metal layer 11,12 of the first composite metal-plastic pipe 1 and the second composite metal-plastic pipe 2 one ends is inserted in respectively in the outside of link 3, is welded and fixed by the cold welding agent between them.
Although above the utility model is had been described in detail, the utility model is not limited to this, and those skilled in the art of the present technique can carry out various modifications according to principle of the present utility model.Therefore, all modifications of doing according to the utility model principle all should be understood to fall into protection domain of the present utility model.
