Abstract
A plastic socket elbow is formed by connecting a straight-pipe elbow pipe with two flared socket pipes. The straight-pipe elbow pipe is made of the plastic wound structural wall pipe, the flared socket pipes are integrated structural members formed by injection molding, and the two flared socket pipes are respectively fused and connected with two openings of the straight-pipe elbow pipe through hot-melt adhesive. The utility model has the advantages of a rational structure, firm sol welding, high ring stiffness, convenient and quick installation, corrosion resistance and non-leakage, and saves raw materials.
Description
Technical field
The utility model relates to a kind of plastic tube, relates in particular to a kind of spigot and socket type plastic elbow and preparation method thereof.
Background technique
Being tightly connected between the spigot and socket type pipe joint that mainly is used in threeway, elbow, flange, application such as direct and the plastic pipe put in the tipping of the spigot and socket type pipe of plastic pipe.Being tightly connected between existing spigot and socket type pipe joint and the plastic pipe mainly is to rely on " hot blast welding ", " thermosol connection ", " glue connection " mode to seal.The drawback of " hot blast welding " is, can't install in inflammable and explosive place, and not quick detachable after welding finishes, weld seam is not withstand voltage, easy to leak.The drawback of " thermosol connection " is, when the pipeline more than two carries out doubling installation and pipeline when carrying out high-lift operation, the thermosol workpiece can't use.The drawback of " glue connection " is, is chemical product as the fluid in the pipeline, and chemical product might react with glue, causes to connect to come off.And these sealing means, complex process has certain requirement to workmen's technical merit, implements inconvenient.
In the drainage pipe field, pipe fittings such as the main fingering orchid of PE plastic pipe, reducing, threeway, four-way, small-bore pipe fitting is (below pipe fitting weight 8000 grams, φ 315 and φ 315 following specifications) can produce by Shooting Technique, get product through secondary operations again, most equal tee, elbow can be produced by the weldering system, and the heavy caliber pipe fitting is (more than pipe fitting weight 8000 grams, greater than φ 315 specifications) in flange, reducing, reducing tee since complex structure can not produce by the weldering system.Because weight is big, produce again, then need the investment of huge injection molding machine and mould, do not reach in the market demand under the situation of economic flow rate as adopting Shooting Technique, very inadvisable.
The model utility content
The purpose of this utility model in order to overcome the problems referred to above that prior art exists, provides a kind of spigot and socket type plastic elbow with new structure exactly.
The purpose of this utility model is achieved in that a kind of spigot and socket type plastic elbow, connect and compose by a straight tube swan neck and two flared type socket pipe members, the straight tube swan neck is made by plastic winding structural wall tube, the flared type socket pipe member is the integral structure component of molding and forming, and two flared type socket pipe members are connected with two mouth fusions of straight tube swan neck by hot melt adhesive respectively.
Described straight tube swan neck is welded to connect with the broadband melt flux after cutting moulding by two sections plastic winding structure wall straight tubes and is made.
Described plastic winding structural wall tube is to twine the I-steel shape structured wall plastic tubing of making by plastics square tube spiral.
The utility model spigot and socket type plastic elbow makes it compared with prior art owing to adopted above technological scheme, have following advantage and and characteristics:
1, the tube wall of straight tube swan neck is the I-shape construction wall, under the identical situation of ring stiffness, saves big content of starting materials than solid wall pipe;
2, tubing generally adds other auxiliary agents by high density polyethylene (HDPE) and makes, and light weight is convenient to transportation and installation, corrosion-resistant, only reacts with a spot of organic solvent;
3, adopt the high density polyethylene (HDPE) manufacturing, belong to flexible pipe, good toughness, shock-resistant;
4, adopt winding to add the mode of fusion weld, needn't adopt large-scale injection molding machine, and can satisfy the production needs of the complex pipes of heavy caliber, different bores;
5, have good toughness and plasticity, dry concrete pipe and flexible PVC pipe all can't be by comparison;
6, water tightness is good, adopts the band socket fitting type structure can guarantee to manage interior sewage and does not leak outside, and can comply with asymmetry settlement of foundation, can not produce the disconnection phenomenon of rupture of concrete pipe, and quick and easy for installation.
Description of drawings
The structural representation of Fig. 1 the utility model spigot and socket type plastic elbow.
Embodiment
Referring to Fig. 1, spigot and socket type plastic elbow of the present utility model, connected and composed by a straight tube swan neck and two flared type socket pipe members 21,22, the straight tube swan neck is welded to connect with broadband melt flux 3 after cutting moulding by two sections plastic winding structure wall straight tubes 11,12 and is made.Plastic winding structural wall tube is to twine the I-steel shape structured wall plastic tubing of making by plastics square tube spiral.The flared type socket pipe member is the integral structure component of molding and forming, and two flared type socket pipe members 21,22 are connected with two mouth fusions of straight tube swan neck by hot melt adhesive 4 respectively.
The structure wall thickness of the plastic winding structure wall straight tube in the utility model can be by adjusting the internal mold rotational speed control of forming machine, spiral angle and roundness can be by adjusting the internal mold angle of swing control of forming machine, the flared type socket pipe member can pass through more mold exchange, and the relative position of adjusting mould is to realize the manufacturing of different bores, different wall.
The tube wall of the plastic winding structure wall straight tube in the utility model is smooth, and flared type socket pipe member design bore is big slightly, connects at socket joint to finish, it is smooth that tube wall still keeps, and the corner part welding has certain circular arc, makes the whole pipe inwall smooth, reduces the water resistance coefficient.
The pipeline structure of the plastic winding structure wall straight tube in the utility model is to the helix structure that is tilt fixing, because of several angle being arranged with pressure-bearing direction (being generally level or vertical), slowed down pressure to a certain extent, compare with the straight burr pipeline of directly extruding, be not prone to whole section obscission, the welding of the tubing of threeway simultaneously also is to adopt material welding of the same race, socket pipe member also is to adopt material fusion of the same race to be formed by connecting, can make the cold and hot contraction of spigot and socket type plastic elbow of moulding synchronous, avoid coming off, leaking.
