Abstract
The utility model relates to a connecting member for aluminum-plastic composite pipes. The connecting member for aluminum-plastic composite pipes is composed of aluminum alloy pipe connecting members and plastic inner linings. The aluminum alloy pipe connecting member (1) is formed into a tee by large circular pipes (4), (5), and (6), and T-shaped small circular pipes (7) and (8) in the middle. The aluminum alloy pipe connecting members (2) and (3) are formed into a straight way and a bent head by large circular pipes (4) and (5) on two ends, a small circular pipe (9) in the middle, and a bent pipe (10). The large circular pipes are provided with outer threads, and inner holes are conical holes. Cylindrical holes are arranged in the small circular pipes (7), (8), and (9), and the bent pipe (10). The plastic inner linings (11), (12), and (13) are respectively cylindric T-shaped, straight cylindric, and bent cylindric. The plastic inner linings (11), (12), and (13) are respectively compounded on the inner walls of the aluminum alloy pipe connecting members (1), (2), and (3). The connecting member for aluminum-plastic composite pipes has clean no poison, corrosion resistance, and durable use performance. The utility model is suitable for drinking water pipelines, gas pipelines, and chemical industry pipelines.
Description
The utility model relates to Pipe jointing part, particularly a kind of plastic-aluminum combined pipe connector that is lined with plastics in the Al-alloy pipe inner nosepiece wall.
Aluminum alloy is as a kind of stock of pipeline fitting in the prior art, have in light weight and mechanical strength high, the surface is difficult for characteristics such as corrosion, can be used as general liquid conducting pipes coupling, but exist under the situation of chlorion in tap water, aluminium and aluminum alloy can corrode, even the appearance point corrosion, aluminium ion is separated out and is increased, and has so just limited the use in water supply system of aluminium and aluminum alloy.
Plastics (as polyethylene etc.), chemical property is stable, have characteristics such as nontoxic, corrosion-resistant, light weight, it is the good material of making the drinking water pipeline system, but the mechanical strength of plastics own is not high, and aging quality resistance is poor, surperficial subject to damage, being heated, the back is easy to produce distortion, so has also dwindled the using scope in pipe-line system.
The purpose of this utility model is: the plastic-aluminum combined pipe connector that is lined with plastics in a kind of is provided, can be used as pipe joint member in the pipe-line system of carrying potable water, combustion gas and chemical liquid.
Formation of the present utility model: constitute by Al-alloy pipe fitting and plastic inner lining, Al-alloy pipe fitting (1) (2) (3) is plastic-aluminum combined pipe connector shell, plastic inner lining (11) (12) (13) is plastic-aluminum combined pipe connector internal layer, Al-alloy pipe fitting (1) is formed threeway by big pipe (4) (5) (6) and the middle little pipe of T shape (7) (8), Al-alloy pipe fitting (2) is formed straight-through by the big pipe (4) (5) and the middle little pipe (9) at two, Al-alloy pipe fitting (3) is formed elbow by the big pipe (4) (5) and the middle bend pipe (10) at two, on the outer cylinder of big pipe (4) (5) (6) screw thread is arranged, endoporus is the little conical bore of outer imperial palace, cylindrical hole in conical bore and little pipe (7) (8) (9) and the bend pipe (10) is communicated with, plastic inner lining (11) is cylindric T font, plastic inner lining (12) is straight tubular, plastic inner lining (13) is curved tubular, is compounded in respectively on the inwall of Al-alloy pipe fitting (1) (2) (3).General pipe connectors such as that plastic-aluminum combined pipe connector can make is straight-through, elbow, threeway, reducer union.
Compared with the prior art, the utility model is rational in infrastructure, employing is at Al-alloy pipe fitting plastic lining layer, can make this plastic-aluminum combined pipe fitting avoid deficiency on independent two kinds of performances of material own, and have the overall merit of two kinds of materials, promptly have clean nontoxic, corrosion-resistant, mechanical strength is high, premium properties such as not aging, durable in use and in light weight.
Accompanying drawing 1 is the utility model three-way pipe fitting structural drawing;
Accompanying drawing 2 is the utility model straight-through tube fitting structural drawing;
