Embodiment
Below in conjunction with accompanying drawing and embodiment the technological scheme of the utility model is carried out detailed elaboration.
FRP is the abbreviation of Fiber Reinforced polymer (fibre reinforced materials).
To shown in Figure 3, the utility model provides a kind of pipe joint like Fig. 2, comprises sleeve pipe 5, is fastened on the FRP material 6 of said sleeve pipe 5 outer surfaces.Under the situation that guarantees pipe joint each item performance index, effectively reduce the wall thickness of sleeve pipe 5, reduce cost of material and material weight; And adopt FRP material 6 to meet environmental protection, conservation-minded society's growth requirement.The pipe joint that the utility model is produced, FRP material 6 can connect through insertion for smooth shape makes between the tubing, has solved the narrow limitation of pipe applications well.
Said FRP material 6 comprises reinforcing fiber and resin.The weight percentage of reinforcing fiber is 75%, and the weight percentage of resin is 25%.Said reinforcing fiber is any one in glass fibre, aramid fibre, polyvinyl fiber, basalt fibre, graphite fiber, ramee, flax fiber, the jute fiber.Said reinforcing fiber preferably can be the chopped strand prepreg.The chopped strand prepreg is cut through the fibrous cutter weak point through wet method and long filament and is formed.Said resin is any one in the unsaturated resin, epoxy resin, vinyl ester resins in the thermosetting resin.When specifically selecting vinyl ester resins for use, the vinyl ester resins glue is to be mixed by vinyl ester resins, coupling agent, inner pattern releasing agent applicable, benzoyl peroxide, peroxidized t-butyl perbenzoate, vinyl benzene, water-thickening agent, filler and mill base; Wherein, get parts by weight and be 100 parts vinyl ester resins, the parts by weight that add other each component again are: coupling agent 0.5-3.0 part; Inner pattern releasing agent applicable 1-1.5 part; Benzoyl peroxide 0.2-1.0 part, peroxidized t-butyl perbenzoate 0.8-1.8 part, vinyl benzene 2-10 part; Water-thickening agent 2-5 part, filler 3-10 part and mill base 0.5-1.5 part.
Said sleeve pipe 5 is metal tubes such as Stainless Steel Tube, copper pipe or aluminum pipe.Said sleeve pipe 5 thickness are 0.2～1.2mm, and the thickness that can select said sleeve pipe 5 is 0.5mm, and preferably the thickness of sleeve pipe 5 is 0.2mm; Thickness >=the 1mm of said FRP material 6, the thickness of preferably said FRP material 6 are 3～10mm.The utility model can adopt the sleeve pipe 5 of 0.2mm limit wall thickness to support as inwall; Sleeve pipe 5 guarantees its corrosion resistance; Performances such as internal pressure-resistant change consumption, thickness or the material of outsourcing FRP material 6 by the product specification requirement, can effectively guarantee under the condition of each item mechanical property requirements of tubing; Reduce cost of material and material weight, cost advantage and weight advantage are provided for product uses.
Said pipe joint can be set to many logical types according to concrete needs, two pass joints as shown in Figure 2, and tee union as shown in Figure 3 also can be the inconsistent different pass joint of import and outlet diameter.The port of preferably said sleeve pipe 5 is provided with the screw thread with the tubing threads engaged that will be connected, and is that the joint of outside thread, sleeve pipe 5 ports just is correspondingly provided with the internal thread of cooperation like the tubing joint; When the tubing joint is an internal thread, the joint of sleeve pipe 5 ports just is correspondingly provided with the outside thread of cooperation; Pipe joint is provided with screw thread and makes and can be connected with tubing through screw thread, has solved the narrow limitation of pipe applications well.
As shown in Figures 2 and 3; Pipe joint also is provided with seal ring 4 in the joint of sleeve pipe 5 ports and tubing; Also can along the tail end that sleeve pipe 5 central directions extend a socket joint circle be set at sleeve pipe 5 screw threads, make pipe joint seal, firmly effectively be connected with tubing without seal ring 4.
As shown in Figure 1, the preparation method of the utility model pipe joint comprises the steps:
(1), put into mould 1, fixing in positioning work piece and thread forming mould 3, location and at sleeve pipe 5 ports and tubing joint formation screw thread according to the sleeve pipe 5 of concrete needs shape such as logical or threeway with two;
(2), will be packed into according to the FRP material 6 of weight calculated value weighing in the mould 1;
(3), compression and moulding: mould 1 matched moulds is placed on the working platform of hotpress 2, and heating, pressurization make FRP material 6 at sleeve pipe 5 outer surface solidifyings;
(4), after the heat cure, apocatharsis hotpress 2 pressure are opened mould 1, take off pipe joint blank spare.
(5), the burr of excision pipe joint blank spare, promptly be trimmed to satisfactory pipe joint finished product.
Preferentially, said compression and moulding is die pressing or injection moulding.Mold pressing is the Chinese translation of compression moulding, and compression moulding claimed again in the abbreviation of compression molding.Plastics or rubber size are shaped to the plastic working method of goods by heating, pressurization in closed mould cavity.Generally be with powdery, granular, granule shape, sheet, even make the material base with the goods similar shape earlier, be placed in the die cavity of heated mold that mold closing pressurization then makes its moulding and solidifies or sulfuration, gets goods through the demoulding again.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is only limited to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
