Abstract
The invention relates to a fiberglass reinforced plastic ribbed pipe straight joint, which is characterized in that the straight joint has a cylindrical shape and is formed of upper and lower cylindrical bodies connected by a bolt, there are internal threads on the inner wall of the joint, the outer wall of the joint has a smooth surface, flanges for connection are arranged on the left and right sides of the upper and lower cylindrical bodies, a gasket is arranged between the flanges, the upper and lower flanges and the gasket are connected via a bolt, internal threads for connection with a fiberglass reinforced plastic ribbed pipe are embedded in the inner cavities at the left and right ends of the joint, the tube inside diameter of the ribbed pipe straight joint is 50-1,000mm, and the ribbed pipe straight joint is made from a fiber reinforced thermosetting resin molding material SMC (sheet molding compound) or BMC (bulk molding compound) by hot pressing. Compared with prior arts, the inventive straight joint has high strength because the inner side of the joint has thread grooves matching with the outer side of the ribbed pipe so as to tightly connect pipes; has good corrosion resistance and long service life; and is a simple, firm and quick joint.
Description
[technical field]
The invention relates to the conveyance conduit joint of draining, blowdown, optical fiber, cable, highway and railway underground construction, water conservancy irrigation, chemical industry, mine fluid, specifically a kind of glass fiber reinforced plastic finned tube straight joint.
[background technique]
Along with China's expanding economy is to municipal engineering, electric power system, chemical industry, communication, the requirement of water conservancy irrigation safety also improves day by day, therefore select good conveyance conduit even more important, for a long time, conveyance conduit adopts metallic material to make, as steel pipe, iron pipe etc., traditional metal materials pipeline due to its production process energy consumption large, operation mainly with and actual use in humidity, dirty long-pending thing, metallic conductivity in the rugged environment such as coastal salt fog, easy-to-rust, life-span is short, shortcomings such as facility maintenance expense is high and being gradually eliminated, the substitute is various New Type Material pipeline.Now commercially common pipeline, the various single plastic pipe such as PVC of extruding and moulding and the various hollow plastic having glass fiber reinforced plastics composite material Wrapping formed is provided with the plastic ripple pipeline of reinforcement.
A kind of appearance of new glass fibre reinforced plastic riffled tube, its joint uses traditional joint cannot meet the requirement of use, the connection of glass fiber reinforced plastic finned tube cannot be welded as plastic film capicitor, if stick with glue straight cutting as Plastic Flat pipe, due to ripply existence, its sealing is not very reliable, so a kind of new connecting means will be found, ensure the use of new pipeline.
[summary of the invention]
Object of the present invention, in order to solve above-mentioned contradiction, is met the need of market, and according to moulded glass steel manufacturing technology principle, adopts the molding material SMC of short fiber reinforced or BMC compression molding to produce the straight joint of this glass fiber reinforced plastic finned tube.
For achieving the above object, design a kind of glass fiber reinforced plastic finned tube straight joint, it is characterized in that the shape of this straight joint is cylindrical body, be bolted together by upper and lower two semicylinders, the inwall of straight joint is internal thread; The outer wall of straight joint is smooth surface, upper and lower cylindrical the right and left of straight joint is respectively equipped with Flange joint, be provided with pad between upper lower flange, upper lower flange bolt connects, and the inner chamber at two ends, straight joint left and right embeds the internal thread connecting glass fiber reinforced plastic finned tube road respectively; The ips of described riffled tube straight joint 50 ~ 1000 millimeters, hot-forming by fiber reinforced thermosetting resin molding compound SMC or BMC.Described fiber adopts glass fibre, carbon fiber or basalt fibre or aramid fiber.Described resin is the high-performance thermosetting resin of epoxy resin or polyester resin or phenolic resin or modification.High-performance thermosetting resin: urea formaldehyde resin, melamine formaldehyde resin, unsaturated resin, polyurethane, polyimide etc. strengthen resin, comprise the thermosetting resin of alternative glass.Described straight joint inwall internal thread is meshed with the outside thread in glass fiber reinforced plastic finned tube road.
The invention compared with prior art, the inner side of straight joint with riffled tube outside the thread groove that matches, pipe can be linked together tightly, straight joint material adopts short fiber reinforced thermosetting resin molding compound SMC or BMC hot pressing to form, intensity is high, easy to use, and corrosion-resistant, long service life, is one joint succinctly, firmly and fast.

Fig. 2 is longitudinal schematic diagram of the invention Fig. 1;
Fig. 3 is the horizontal schematic diagram of the invention Fig. 1;
See Fig. 1,1 is the glass fiber reinforced plastic finned tube of left end, and 2 is riffled tube straight joint.
See Fig. 2,3 is corrosion-resistant bolt, and 4 is rubber cushion.
See Fig. 3,5 is the internal thread groove of straight joint.
[embodiment]
Below in conjunction with accompanying drawing, be described in further details the invention, the mounting technique of this straight joint is clearly concerning the people of this specialty.
Fig. 1 gives the organigram of this joint.
See Fig. 1, the riffled tube (1) that will connect is stitched together, and joint cylindrical body separates up and down, thread groove (5) on upper and lower cylindrical body is aimed at the outside thread on riffled tube (1) surface, close up upper and lower cylindrical straight joint, add rubber cushion, lock bolt can complete the invention.Straight joint material therefor is short fiber reinforced molding compound SMC or BMC, and resin material is epoxy, polyester or phenolic resin.
