Abstract
By means of the thermal swelling property of plastics, non-toxic polyvinyl chloride pipe is heated and pressured in special equipment to stick closely onto inner wall of galvanized steel pipe and to form non-toxic composite pipe.
Description
The present invention is a kind of relating to metal tube and non-toxic plastic pipe through the compound method of water pipe and the device of use thereof of manufacturing, and belongs to building materials water pipe class.
At present commercially available galvanized metal pipe and hard non-toxic polyvinyl chloride plastic tube respectively have pluses and minuses when being used separately as running water pipe: galvanized pipe has high compression strength, but easily produces the corrosion polluted water, and it is little that plastic tube can the corrosion resistance to water-flow, but compressive strength is lower.These two kinds of Guan Ruojing are combined into water pipe, just can comprehensively bring into play both strong points, avoid weakness.Claim according to the Japan clear 60-47088 of special permission communique, can make the water pipe of galvanized metal pipe and PVC pipe jointing with the method for die drawn diameter reduction.
Method with the stretching undergauge might make water pipe become non-standard product, and influence is installed and used.Make simultaneously in this way that the equipment pulling force is big, processing water pipe difficulty is also big.The present invention adopts the thermosol polyvinyl chloride pipe that expands to make it method with the compound manufacturing water pipe of galvanized pipe, and it both can make the water pipe with the comprehensive strong point of metallo-plastic, can reduce non-standard product again and occur.
Technological scheme of the present invention is: behind the even spraying binder of nontoxic rigid PVC tube outer surface, insert in the galvanized metal pipe, in specific device with heat medium to pvc tube seal the heating pressurization make its heat expansion and cling Coating Steel Pipe inwall, cooling back composite water pipe.Specific device is made up of air exhaust loop (3), rubber stopper (4), honeycomb duct (5,5 '), locking device (7) valve (6,6 '), but wherein air exhaust loop has the aperture of exhaust.Heat medium both can be gas (as steam, a nitrogen), also can be that liquid (as glycerine, mineral oil), its temperature are 140～170 ℃, and pressure is 1～4kg/cm
2
Now in conjunction with the accompanying drawings shown in 1, details are as follows:
The Vybak pipe (2) that the surface was evenly sprayed tackiness agent inserts in the Coating Steel Pipe (1), and plastic tube (2) two ends are longer slightly and fill in rubber stopper (4) than steel pipe (1) two ends.Simultaneously after the both ends of the surface of galvanized pipe (1) are loaded onto air exhaust loop (3), with locking device (7) locking both ends of the surface, at last having valve (6,6 ') honeycomb duct (5,5 ') by rubber stopper (4), the central authorities of locking device (7) are stayed in mouthful insertion plastic tube (2), install.Close outlet valve (6 ') this moment, opens inlet valve (6), feeds the glycerine that has been heated to 170 ℃ at honeycomb duct (5) and be full of plastic tube (2), simultaneously thermal medium glycerine is forced into 1～4kg/cm
2Treating that plastic tube (2) heat expansion and galvanized pipe (1) cling is one, and opens valve (6 ') and discharge glycerine release cooling behind the heat-insulation pressure keeping in a moment, cleans through inside through compound water pipe again, cut plastic tube (2) two ends elongated portion, galvanized pipe and the compound finished product water pipe of polyvinyl chloride pipe.
By above-mentioned, apparent the inventive method simple and feasible because of combining the strong point of two pipes, has high economic benefit by the metal-plastics composite water pipe of its manufacturing, and the short method of the undergauge that stretches can reduce the non-standard product appearance again.
With the surface evenly be coated with tackiness agent, external diameter be the nontoxic Vybak pipe of 25mm to insert internal diameter be in the Coating Steel Pipe of 27mm, 12mm is stretched out than the two ends of steel pipe in the two ends of plastic tube.With specific device, press shown in the accompanying drawing 1 packaged.Feed 170 ℃ of glycerine heat carrying agent, close outlet valve, make glycerine be pressurized to 4kg/cm
2, treat that plastic tube thermal expansion and Coating Steel Pipe are compound for one, tubing is also cleaned in release immediately, cooling.
By glycerine heat carrying agent temperature is that 140 ℃, pressure are 1kg/cm
2, all the other conditions are identical with embodiment 1.Can make compound nontoxic metallo-plastic tubing.
Claims (3)
1, a kind of metal tube and plastic tube are combined into the manufacture method of metallo-plastic water pipe, it is characterized in that: behind the even spraying binder of nontoxic Vybak tube-surface, insert in the galvanized metal pipe, in specific device, the Vybak pipe is sealed heating pressurization and makes its heat expansion and cling the galvanized metal inner tube wall with heat medium, the cooling back composite water pipe.
2, according to claim 1, it is characterized in that described heat medium both can be gas (as steam, a nitrogen), also can be liquid (as glycerine, mineral oil), its temperature is that 140～170 ℃, pressure are 1～4kg/cm
2
3,, it is characterized in that described specific device is made up of air exhaust loop (3), rubber stopper (4), honeycomb duct (5,5 '), locking device (7), valve (6,6 '), but wherein air exhaust loop has the aperture of exhaust according to claim 1.
