Abstract
The utility model relates to a joint-type pipe element, which is composed of a left metal-plastic composite pipe, a right metal-plastic composite pipe and a joint element. The metal layer on one end of the left metal-plastic composite pipe and the right metal plastic composite pipe is telescoped inside the connection elements respectively. These elements are fixed by nontoxic and cold-welding. The structure like this can secure the connection fastness of the metal composite pipes with large and medium calibers. Apart from these, the effects such as pressure resistance, oil proof, corrosion resistance, high-temperature resistance, low cost and good air tightness have been obtained as well.
Description
The utility model relates to a kind of articulated pipe fitting.
Applying of present domestic composite metal-plastic pipe is growing, in use, there are some problems in connection for the metal composite pipe of big, medium caliber, because the common wall thickness of metal layer of composite pipe is thinner, the Placement that is not easy to conventional pipe fittings such as tapping, electric welding realizes, if the increase metal layer thickness, its cost greatly increases.The employing that has " electric smelting formula " connects, 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.
The purpose of this utility model be to provide a kind of withstand voltage, oil resistant, wear-resisting, high temperature resistant, cost is low, the articulated pipe fitting of good airproof performance.
For achieving the above object, articulated pipe fitting of the present utility model, form by left composite metal-plastic pipe, right composite metal-plastic pipe, link, the metal layer of left side composite metal-plastic pipe and right composite metal-plastic pipe one end is inserted in respectively in link, and is fixing by nontoxic cold welding agent welding between them.
After adopting such structure, make big, medium caliber composite metal-plastic pipe be connected firmly and have withstand voltage, oil resistant, corrosion resistant, high temperature resistant, cost is low, the effect of good airproof performance.
Fig. 1 is the structural representation of the concrete a kind of embodiment of the utility model.
Articulated pipe fitting of the present utility model as shown in Figure 1, form by left composite metal-plastic pipe 1, right composite metal-plastic pipe 2, link 3, it is characterized in that: the metal layer 11,12 of left composite metal-plastic pipe 1 and right composite metal-plastic pipe 2 one ends is inserted in respectively in link 3, and is fixing by nontoxic cold welding agent welding between them.During application, what connecting tube can crooked shape, also two flanges merge and dig, also can in the middle of the band bellows, also can extend into modes such as threeway connection.
