Abstract
The utility model discloses a metal tube with glass fibre reinforced plastics liner and equipment thereof. The metal tube with glass fibre reinforced plastics liner is that a layer of glass fibre reinforced plastics is extruded on the inner wall of a common metal tube; the product can be realized through the special equipment which comprises an air compressor, an aerocyst, a spray lance, etc. The air compressor is connected with a spray lance; the periphery of the spray lance is provided with one aerocyst; the lengths of the spray lance and the aerocyst are selected according to the length and the diameter of the metal tube. During processing, the aerocyst and the spray lance are inserted into the metal tube; the inside of the aerocyst is pressurized by an air compressor through the spray lance; the glass fibre sleeve on the periphery of the aerocyst and the liquid glass fibre reinforced plastics are extruded on the inner wall of the metal tube; the metal tube with high temperature resistant and high voltage impact resistance can be formed.
Description
The utility model relates to a kind of corrosion-resistant, high temperature resistant, high pressure resistant, shock proof frp lining metal tube and equipment.
Existing inner wall of metal tube has epoxide coal bituminous, epoxy powder electrostatic coating, these two kinds of products are anticorrosive weaker; Patent Office of the People's Republic of China's Gazette of Patent for Invention on May 1st, 1991 disclosed a kind of metal--glass (glaze) heat spray composite anti-corrosive pipeline (publication number CN1051075A) application number 891078568), this kind pipeline has solved the problem of the corrosion resistance difference of above-mentioned two kinds of pipelines, but exists the shortcoming of glass (glaze) impact resistance difference.
The purpose of this utility model provides a kind of frp lining metal tube and equipment, and this product can not only be anticorrosion, and can be high temperature resistant, high pressure resistant, and particularly shock resistance is good, and equipment is the special device of producing this product.
The purpose of this utility model is achieved in that the said equipment of the utility model is to produce frp lining metal tube special device, it is made up of back blanking cover, air bag, spray gun, gun hole, preceding blanking cover, valve (two), liquid glass steel tank, pressure gauge, air compressor, its assembly relation is: air compressor is connected with preceding blanking cover by pipeline, pressure gauge and valve are housed on the pipeline, in the preceding blanking cover with on managing corresponding position spray gun is housed, spray gun is a long tube, and the gun hole of off side is arranged on the circumference of pipe; The liquid glass steel tank connects with the Guan Yuqian blanking cover, valve is arranged on the pipe, outside spray gun, be with length and the duct length of being processed, the air bag that diameter is complementary, before and after blanking cover be to prevent from that the liquid glass steel from leaking outside to be fixed by bolts to processed pipe ends, during processed glass Steel Lining metal tube, to be ready to the glass yarn cover earlier and be enclosed within the air bag periphery, then with the glass silk braid, air bag, spray gun one now inserts in the processed pipeline, the valve of opening simultaneously on the liquid glass cylinder of steel pipeline is emitted liquid glass fibre reinforced plastics, its stream is put at glass yarn, a throttle down when the glass silk braid is inserted into, the all cover screws in front and back are fixed on the pipeline, the startup air compressor is opened valve and is pressurizeed in air bag with spray gun, and air bag is heaved gradually, along with the pressure increase of air bag, the glass silk braid of air bag periphery and liquid glass steel will be bonded on the inwall of metallic conduit gradually, behind extruding certain hour in the pipeline of air bag, blanking cover and air bag before and after pulling down, spray guns etc. are sent pipeline into moist closet and are got final product.
Description of drawings:
Fig. 1 is the utility model general illustration, wherein 1, back blanking cover, 2, pipeline, 3, frp layer, 4, air bag, 5, spray gun, 6, gun hole, 7, preceding blanking cover, 8, valve, 9, liquid glass steel tank, 10, pressure gauge, 11, air compressor, 12, valve.
The extreme length 10m of the utility model process pipeline, diameter at first are processed into the spray gun (5) of the air bag (4) of different-diameter, preceding blanking cover (7), back blanking cover (1) and different length by 76mm to 600mm by this requirement.Spray gun (5) is the long tube of a diameter 24mm, and processing is porose on the circumference of pipe.Assemble by figure after part is got all the ready in addition, its assembly relation following (seeing figure): air compressor (11) connects with Guan Yuqian blanking cover (7), valve (12) and pressure gauge (10) are housed on the pipe, on preceding blanking cover (7) inboard and the corresponding position of pipe spray gun (5) is housed, spray gun (5) is a long tube, and the gun hole (6) of off side is arranged on the circumference of pipe; Liquid glass steel tank (9) connects with Guan Yuqian blanking cover (7), valve (8) is arranged on the pipe, be with a length and pipeline (2) length of being processed, the air bag (4) that diameter is complementary at spray gun (5) outer, back blanking cover (1), preceding blanking cover (7) are to prevent from that the liquid glass steel from leaking outside to be fixed by bolts to the two ends of processed pipeline (2).During processed glass Steel Lining metal tube, ready glass silk braid (length and diameter and processed metal tube are complementary) is enclosed within periphery to preceding blanking cover (7) inboard of air bag (4), valve (8) on liquid glass steel tank (9) pipe is opened, liquid glass steel stream is put at glass yarn, meanwhile the glass silk braid is sent in pipeline (2), air bag (4) is also corresponding with spray gun (5) to send air bag (4) in pipeline (2), spray gun (5), after the glass yarn cover puts in place with preceding blanking cover (7), back blanking cover (1) fixes with bolt and pipeline (2).Throttle down (8) after the glass yarn cover puts in place, at this moment start air compressor (11), opening valve (12) pressurizes in air bag (4), pressure is added to air bag (4) periphery all to be squeezed in glass silk braid and liquid glass steel on the inwall of pipeline (2), the thickness of frp layer (3) is by 1-3mm the best, at this moment show that by pressure gauge (10) pressure should be 8 barometric pressure, this pressure should keep 20 minutes time, and sending into the time of depositing 40 minutes in the greenhouse then promptly becomes the frp lining metal tube.
The utility model environment division is simple in structure, and is easy to operate, the good product quality of producing, and the frp lining metal tube has anticorrosion, high temperature resistant, high pressure resistant, shock proof performance.
