Abstract
The utility model relates to a combined steel-plastic compound fitting-the fitting of a compound steel-plastic pipe which can be used for delivering the corrosive gas and liquid. An internally arranged plastic liner is wrapped by two steel plate bodies (1) and (5); the end parts of the two oppositely connected steel plate bodies (1) and (5) are provided with screw threads and integral flange inner screw thread for connection; a sunk screw (4) is also added at the connecting part between the two oppositely connected steel plate bodies (1) and (5). The combined steel-plastic compound fitting has the advantages of easy production, low cost and reliable performance.
Description
The utility model relates to the accessory of the steel-plastic composite pipe that can carry corrosive gas, liquid.
Corrosion of metal is a harm, and the annual corrosion loss of China can reach two, 30,000,000,000 yuan.Under the situation of carrying corrosive gas, liquid, it is more outstanding that etch-proof problem just seems.Use stainless steel, titanium, it is expensive that anticorrosive materials such as zirconium seem, the present steel-plastic composite pipe that uses---make matrix with carbon steel tubing, the thermoplastic pipe that the liner chemical stability is good, it is a kind of intensity height, corrosion-resistant, long service life, the desirable anti-corrosion pipeline that overall economic efficiency is good, accessory as steel-plastic composite pipe, as elbow connection, tee union, the fitting of cross fitting and other pattern, because cavity shape complexity, the lining of accessory often adopts subsides rubber, lining bath of glass pottery, methods such as lining glass fibre, though these methods all have certain anticorrosion ability, but certain deficiency is arranged respectively, rubber lining tends to occur weak bond and pitting corrosion phenomenon, the bath of glass ceramic lined enbrittles, fiberglass skin is owing to adopt the manual subsides that are coated with, thickness is irregular, easily produces hole, also is difficult to processing for small-bore accessory.
In order to overcome above-mentioned deficiency, it is compound to adopt steel to mould too to the accessory of steel-plastic composite pipe.In view of the accessory complex structure, adopt combined steel to mould compound accessory.
Description of the present utility model is as follows: the lining that combined steel is moulded compound accessory is the plastics inner bag of processing with the thermoplastic mould, make the structure of elbow, threeway, four-way or other pattern as required, its material is a polypropylene, or polyethylene, or poly-six ethene, or teflon, with polypropylene for well.The accessory steel body that matches with the plastics inner bag, be positioned at the inner bag outside is cast iron or cast steel casting, that have involutory shape, and promptly accessory steel body is combined into by two and half slit bamboo or chopped woods.After two and half slit bamboo or chopped woods are involutory, in anchor clamps, by cutting, make its internal diameter and the consistent ， And of plastics inner bag external diameter in the cutted thread of the end of accessory joint.Flange is the internal thread that matches of turning also, is connected with the accessory joint by screw thread, as hoop two and half slit bamboo or chopped wood steel bodies is combined into integral body, connects with sunk screw in the involutory connection place of steel body two slit bamboo or chopped woods simultaneously.Being painted in the outside, makes the steel of all size requirement and mould compound accessory again.
Further narrate below in conjunction with drawings and Examples.
Fig. 1 moulds compound accessory for steel of the present utility model.Among the figure 1---the steel body, 2---the plastics inner bag, 3---flange, 4---sunk screw.
Fig. 2 is Figure 1A-A sectional view.Among the figure 1,5---the steel body.
With internal diameter is that 50 millimeters steel are moulded compound threeway accessory as present embodiment.Plastics inner bag (2) is made material with polypropylene, and by the injection machine molding and forming, internal diameter is 50 millimeters of φ, and external diameter is 60 millimeters of φ.Steel body (1), (5) are involutory shape, by casting, are grey cast iron or cast steel.In anchor clamps with the boring of steel body internal diameter to 60 millimeters of φ.Threeway end turning outside thread M74.To flange (3) Internal Threading M74.On the corresponding position of steel body (1), (5) the two involutory joints of slit bamboo or chopped wood, Yi Bian 7 millimeters of the φ of punching, Yi Bian tapping M6.Be combined into accessory by following order: plastics inner bag (2) is placed inside; the outside is involutory two slit bamboo or chopped wood steel bodies (1), (5); precession integral (type) flange (3); advance sunk screw (4) at steel body (1), (5) involutory joint spiral shell again; go up 4 attachment holes of brill at flange (3); at the end face of flange plastics flange of burn-oning, coat protective paint at outer surface at last, knockdown steel is moulded compound accessory and has just been carried out.
The advantage of combined steel-plastic compound fitting of the present utility model: can utilize the good steel body of intensity and the good plastics of antiseptic property to be combined into accessory, owing to adopt combined type, make and make simply, not need complex apparatus, technology is simple, and is with low cost; The accessory service behaviour is good: durable in use.
Claims (2)
1, a kind of accessory-combined steel that relates to the steel-plastic composite pipe that can carry corrosive gas, liquid is moulded compound accessory, it is characterized in that the involutory steel bodies of two slit bamboo or chopped woods (1), (5) encase the plastics inner bag (2) that places inside, the involutory steel bodies of two slit bamboo or chopped woods (1), (5) end have screw thread and integral (type) flange to be threaded, and also are added with sunk screw (4) in the connection place of the involutory steel bodies of two slit bamboo or chopped woods (1), (5).
2, combined steel according to claim 1 is moulded compound accessory, it is characterized in that plastics inner bag (2) makes material with polypropylene or polyethylene or poly-six ethene or teflon, molding and forming, and grey cast iron or cast steel are adopted in steel body (1), (5).
