Description
Technical field
The utility model relates to plastic tubes and steel pipe connection area, produce more particularly, to a kind of steel modeling transition from cuff structure
Product.
Background technique
Current plastic tube, especially polyethylene pipe have obtained universal application in pipeline engineering, in engineering construction, warp
It is commonly encountered the connectivity problem of plastic tube and steel pipe.A kind of engineering proposal is using flanged joint, and another method is moulded using steel
The method of transition connects.It is a kind of more easy-to-use scheme using flanged joint, but bolt used in flanged joint is difficult
Anti-corrosion is done, there are problems easy to aging for the sealing ring that flanged joint uses, if but needed using the higher sealing element of hardness higher
Bolt fastening strength, anticorrosion difficulty existing for flanged joint and sealing difficulty often make flanged joint position become pipeline
The weak spot of system.It is a kind of preferable solution that steel, which moulds transition, uses integrated Joining Technology, is not mechanically connected
Existing disadvantage.Steel modeling transition moulding process multiplicity currently on the market, reliable moulding process is injection molding, still
The process program needs higher technological equipment investment, becomes very uneconomical in the steel modeling transition molding of larger caliber.It passes
The steel modeling transitional product structure of system is that steel pipe is inserted into plastic tube, and due to needing bearing capacity to design, steel pipe needs to retain foot
Enough wall thickness, cause circulation area of pipeline to become smaller, and application will affect the negotiability of pipeline in main pipeline engineering, play
The big advantage of plastic conduit negotiability is not gone out.
Summary of the invention
The purpose of this utility model is that solve the deficiencies in the prior art, and provide a kind of from hoop
The steel of structure moulds transitional product.
The new technical solution of the utility model is: a kind of steel from cuff structure moulds transitional product, including steel pipe, steel bearing sleeve,
Steel nesting and plastic tube, the steel nesting is equipped with minus thread or sets one's teeth on edge, and steel nesting is welded on steel pipe one end；The steel is held
It is arranged with internal screw thread, and steel bearing sleeve is welded on steel pipe one end, is equipped with process inspection hole at the steel bearing sleeve and steel-pipe welding；Institute
The steel bearing sleeve and steel stated are nested to form embedded space, are equipped with plastic tube in the embedded space.
The steel bearing sleeve even circumferential is equipped with process inspection hole 2-6.
The steel bearing sleeve internal diameter is greater than steel nesting outer diameter.
The plastic tube is polyethylene.
The utility model has the following beneficial effects: steel bearing sleeve progress preservative treatment nested with steel in the utility model, solves steel
Prepared material etching problem；Steel bearing sleeve using minus thread or is set one's teeth on edge, the root that steel bearing sleeve is contacted with steel pipe using internal screw thread, steel nesting
If process inspection hole, Product Process performance is improved, guarantees product quality of connection.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the enlarged drawing in the portion A in Fig. 1.
Wherein: 1 be steel pipe, 2 be steel bearing sleeve, 3 be steel it is nested, 4 be plastic tube, 5 be process inspection hole.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
A kind of steel modeling transitional product from cuff structure, including steel pipe 1, steel bearing sleeve 2, steel nesting 3 and plastic tube 4, it is described
Steel nesting 3 is equipped with minus thread or sets one's teeth on edge, and steel nesting 3 is welded on 1 one end of steel pipe；The steel bearing sleeve 2 is equipped with internal screw thread, and steel
Bearing sleeve 2 is welded on 1 one end of steel pipe, and the steel bearing sleeve 2 and 1 weld of steel pipe are equipped with process inspection hole 5；The steel bearing sleeve 2
Nested with steel 3 form embedded space, are equipped with plastic tube 4 in the embedded space.
2 even circumferential of steel bearing sleeve is equipped with process inspection hole 52-6.
2 internal diameter of steel bearing sleeve is greater than nested 3 outer diameters of steel.
The plastic tube 4 is polyethylene.
It is welded after the 3 machined molding nested with steel of steel bearing sleeve 2 in 1 one end of steel pipe and carries out preservative treatment.
Steel bearing sleeve 2 is equipped with internal screw thread, suit is rotated when plastic tube 4 is connect with steel pipe 1, plastic tube 4, which is inserted into steel part, to be made
It is embedded in screw thread and realizes steel modeling connection, steel pipe 1 and plastic tube 4 is made to be not easy to loosen.
Steel nesting 3 is equipped with minus thread or sets one's teeth on edge, and plastic tube 4, which more easily screws in, is embedded in space, reinforces steel and moulds connection effect,
Improve anti-loose ability.Steel nesting 3 and steel bearing sleeve 2, which are formed, is embedded in space, and plastic tube 4 melts end insertion and is embedded in area, with steel
Part forms reliable the problem of being embedded in, being not in melt influence circulation area of pipeline.
The root that steel bearing sleeve 2 is contacted with steel pipe 1 is equipped with 2-6 process inspection hole 5, when plastic tube 4, which is full of, is embedded in space,
Extra melt can be overflowed from process inspection hole 5, facilitate monitoring forming quality of products.
