Know in technology, existing steel pipe and plastic tube mating conversion pipe fitting are mainly connected through a screw thread injection molded polyethylene by coupling
Plastic pipe joint composition, but limited by its construction, unreasonable structural design, especially coupling and plastic pipe joint
The connection of intersection is to intersect vertically, wedge angle transition mutation structure, so that it is also easy to produce local bulge, crackle, deformation after being pressurized,
In practical application, coupling and the mating of plastic pipe joint are easy to slide fastener, and the connection that cooperates is not close, leakproofness compared with
Difference, emerged in operation loosening causes to leak when long, and there are insecurity factors, or even cause environmental pollution, in actual use especially
It is that conveying natural gas, oil product etc. are restricted, and brings inconvenience to using.
Utility model content
For overcome the deficiencies in the prior art, it solves existing steel pipe and plastic tube mating conversion fitting structure design does not conform to
Reason, leakproofness is poor, after compression the problem of local bulge, crackle, deformation.The purpose of the utility model is to provide a kind of structure letter
Single practical, coupling and plastic pipe joint mutual cooperation are completely embedded, good airproof performance, not bulge after compression, not crackle, no
Deformation, integral strength is high, and coupling and the connection of plastic pipe joint intersection are arc chord angle smooth transition, and hot-melting and injection-molding is held
Inserting is connected into type product qualified rate height, applied widely, runs new-type steel pipe and plastic tube mating transition safe and convenient to use
Convert pipe fitting.
The technical scheme in the invention for solving the above technical problem is:
A kind of threaded connection injection molding steel modeling conversion pipe fitting, it includes: joint for plastic tube, coupling, hot melt spigot-and-socket formula
It is welded pole, the coupling is that 3-6 is formed on steel-plastic pipe union body with the steel-plastic pipe union of diameter and reducing branching pipe joint, steel
It is formed with the road 1-4 annular groove on the coupling body of plastic pipe union mating joint for plastic tube, is fitted with heat on the joint for plastic tube
Molten spigot-and-socket is welded pole.
Above-mentioned threaded connection injection molding steel modeling conversion pipe fitting, the 3-6 of the steel-plastic pipe union is the same as diameter and reducing branched pipe
Vertical arc reinforcing rib, circular cone tubular type reinforcing rib, any reinforcing rib in oblique supporting plate reinforcing rib are formed in the ring body of connector bottom,
And the reinforcing rib of other adaptive types.
Pipe fitting is converted in above-mentioned threaded connection injection molding steel modeling, the road ring of steel pipe branch fitting body in the steel-plastic pipe union
The trench bottom of shape slot is formed with the transition arc of annular groove, transition arc >=0.4.
Joint for plastic tube steel pipe branch is coupled in above-mentioned threaded connection injection molding steel modeling conversion pipe fitting, the steel-plastic pipe union
It is formed with the uniformly distributed longitudinal slot in the road 2-10 in the outer round body of fitting body junction end, the transition circle of longitudinal slot is formed on longitudinal slot
Arc, transition arc >=0.4.
Pipe fitting is converted in above-mentioned threaded connection injection molding steel modeling, and steel pipe is coupled in steel pipe branch connector in the steel-plastic pipe union
Connector portions screw thread in be formed with annular groove, be installed with elastic seal ring in annular groove.
When the utility model is used, according to design requirement and actual needs, the steel-plastic pipe union of the utility model is made for together
The internal screw thread of diameter or reducing adaptable model, externally threaded plastic tube branch joint, steel pipe branch connector, according to reality
Need, carry out it is prefabricated or it is live be coupled to correspondingly delivery main road, on lateral, pipeline operation can be carried out.
Since the utility model design uses above-mentioned technical proposal, efficiently solves existing steel pipe and plastic tube is matched
Connect that conversion fitting structure design is unreasonable, and leakproofness is poor, after compression the problem of local bulge, crackle, deformation.Also by for several times
It is simple and practical in structure that actual tests result on trial shows that it has, and coupling and plastic pipe joint cooperate connection tightly
It is close, good airproof performance, not bulge, not crackle, indeformable, integral strength height, coupling and plastic pipe joint intersection after compression
The connection at place is arc chord angle smooth transition, and shaping finished product qualification rate height is coupled in hot-melting and injection-molding socket joint, and applied widely, operation uses
The advantages that safe ready, it is defeated to be suitable for aqueduct, liquid conducting pipes, oil gas mixture conveyance conduit, natural gas and biogas
Send pipeline etc..
