Description
Technical field
The utility model belongs to a kind of plastics (comprising PE) flanged joint in plastic conveying and plastic conduit component technical field.
Background technique
Injection molded polyethylene (PE) flanged joint is widely used in combustion gas, feedwater and liquid conducting pipes.Along with continuous progress and the development of combustion gas, feedwater and liquid conducting pipes, also more and more higher to the technical requirements of plastics used (comprising PE) flanged joint.In known technology, existing injection molded polyethylene plastics flange joint be by plastics pipe end, circular cone and flange plate three part form.But limit by its structure, its structural design is unreasonable, because the wall thickness of plastics pipe end differs more with between the thick and flange plate wall thickness of the large end wall of circular cone, when adopting polyethylene (PE) tube material injection molding flanged joint, in view of polyethylene (PE) tube material has high melt viscosity and wider molecular weight distribution usually, therefore injection molded flange joint not only appearance more easily there is pit, buckling deformation, and it is more to produce hole in flanged joint inside, cause bulk strength low, especially the increase of injection molded flange joint specification, the probability that its inner void defect occurs increases, the volume of inner void also increases thereupon, hole presents arc strip and has the trend extended gradually along flanged joint circumference, What is more, and its hole circumference runs through whole flanged joint, annular aperture hole defect is formed in flanged joint wall thickness biggest place inside, cause the injection-molded finished up-to-standard rate of flanged joint lower, use is restricted.
Model utility content
In order to overcome the deficiencies in the prior art, solve existing injection molded polyethylene plastics flange joint structure and design unreasonable, inner void is more, the problem that bulk strength is low.The object of the utility model is to provide a kind of simple and practical, novel plastic (the comprising PE) flanged joint of the mechanical strength of flanged joint and the integral rigidity of pipe fitting, good seal performance.
The technical scheme in the invention for solving the above technical problem is:
A kind of novel plastic flanged joint, it comprises: flanged joint body, the plastics pipeline section of flanged joint body with on be connected flange plate also the conjuncted L-type that is shaped with strengthen gusset and ring strengthens gusset, consist of the flanged joint of single injection-molded.Due to the setting of L shape gusset and ring gusset, save cost of material than existing structure scheme, enhance the mechanical strength of flanged joint and integral rigidity, the good seal performance of pipe fitting simultaneously, also improve usability.
Above-mentioned a kind of novel plastic flanged joint, the L-type of described flanged joint body is strengthened gusset and ring and is strengthened all two faces of gusset and intersect part and be round-corner transition, be conducive to that melt viscosity is large, polyethylene (PE) tube material of poor fluidity in injection moulding process smooth mold filling with eliminate stress centrostigma.
Above-mentioned a kind of novel plastic flanged joint, the groove floor surrounding corner that the L-type of described flanged joint body strengthens gusset mutual is arc transition.
Above-mentioned a kind of novel plastic flanged joint, the wall thickness of described flange plate is equal with the wall thickness of plastics pipeline section, and the inside lock radius of plastics pipeline section and flange plate equals the 25%-60% of flange thickness, the best is 50%; The outer knuckle radius of plastics pipeline section and flange plate equals the 100%-200% of flange plate wall thickness, the best is 150%.One is the flowing of melting charge when being conducive to mold filling, the internal stress of reduction injection moulding generation, and two is that injection molding pipe part cooling aftershrinkage evenly reduces surface warp, the defects such as hole and inner void of collapsing.
Above-mentioned a kind of novel plastic flanged joint, the wall thickness that described L shape strengthens gusset equals the 50%-80% of flange plate wall thickness B, and L shape strengthens the 25%-60% that gusset and plastics pipeline section and flange plate and ring stiffening rib plate junction inside lock radius equal flange plate wall thickness.Be conducive to polyethylene and melt material Injection filling and the centrostigma that eliminates stress.
Above-mentioned a kind of novel plastic flanged joint, the wall thickness of described ring reinforcement gusset equals the 50%-80% of flange plate wall thickness, and ring reinforcement gusset and flange plate inside lock radius equal the 25%-60% of flange thickness.Be conducive to polyethylene and melt material Injection filling and the centrostigma that eliminates stress.
When the utility model uses, the same with existing injection molded polyethylene plastics flange joint, according to designing requirement, be fitted to conveyance conduit.
Because the utility model design have employed technique scheme, efficiently solve the design of existing injection molded polyethylene plastics flange joint structure unreasonable, inner void is more, the problem that bulk strength is low.Show through testing result on trial for several times, the advantages such as it compared with prior art has simple and practical, the mechanical strength of flanged joint and the integral rigidity of pipe fitting, good seal performance, applied widely, are applicable to the conveyance conduits such as combustion gas, feedwater and liquid.
