Abstract

The utility model provides a kind of polyvinyl piping materials steel modeling transitional product, wherein tapered thread is equipped with inside described steel pipe one end, described plastic tube one end screws in steel pipe along tapered thread, the plastic tube is lined with inner support, and inner support is located at steel pipe and plastic tube junction, the inner support is thin metal pipe, and the length of inner support is than the outer diameter of long 2/3 plastic tube of length of plastic tube insertion steel pipe;Advantage are as follows: steel pipe is threadedly coupled simple and easy to do with plastic tube in the utility model, and it is reliable and stable that steel moulds transition quality of connection;Plastic tube is lined with inner support, can resist plastic tube insertion steel tubing portions Radial creep stress, can also resist torsion break when plastic tube screws in steel pipe;Manufacturing cost is low, reliable product quality.

Description

A kind of polyvinyl piping materials steel modeling transitional product
Technical field
The utility model relates to plastic tubes and steel pipe connection area, produce more particularly, to a kind of modeling transition of polyvinyl piping materials steel 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, and 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 a kind of polyvinyl piping materials steel modeling transition is provided Product.
The new technical solution of the utility model is: a kind of polyvinyl piping materials steel moulds transitional product, including steel pipe, plastic tube and Inner support, steel pipe one end inside are equipped with tapered thread, and described plastic tube one end screws in along steel pipe along tapered thread, described Plastic tube be lined with inner support, and inner support is located at steel pipe and plastic tube junction, the inner support is thin metal pipe, and inner support The outer diameter of length 2/3 plastic tube longer than the length of plastic tube insertion steel pipe.
The plastic tube is polyethylene.
The inner support is stainless steel or copper.
The utility model has the following beneficial effects: steel pipe is threadedly coupled simple and easy to do, steel modeling with plastic tube in the utility model Transition quality of connection is reliable and stable;Plastic tube is lined with inner support, 2/3 modeling longer than the length of plastic tube insertion steel pipe of the length of inner support The outer diameter of expects pipe, inner support reach optimal support effect, and inner support can resist plastic tube insertion steel tubing portions Radial creep stress, also Torsion break when plastic tube screws in steel pipe can be resisted;Manufacturing cost is low, reliable product quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: 1 being steel pipe, 2 be plastic tube, 3 be inner support.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
A kind of polyvinyl piping materials steel moulds transitional product, including steel pipe 1, plastic tube 2 and inner support 3, in described steel pipe one end Portion is equipped with tapered thread, and described 2 one end of plastic tube screws in steel pipe along tapered thread, and the plastic tube 2 is lined with inner support 3, and inner support 3 is located at steel pipe and 2 junction of plastic tube, the inner support 3 is thin metal pipe, and the length of inner support 3 is than plastic tube 2 It is inserted into the outer diameter of long 2/3 plastic tube 2 of length of steel pipe 1.
The plastic tube 2 is polyethylene.
The inner support 3 is stainless steel or copper.
Embodiment 1: steel pipe 1 cuts into section, processes tapered thread using machining equipment;Inner support 3 cuts into section, removal Surface spikes, end round-corner transition;It is spare that plastic tube 2 cuts into section.Firstly, pre- 2 end of thermal plastic pipe, makes 2 end of plastic tube Surface temperature is at 100-110 DEG C, until 2 insertion end of plastic tube softens;Secondly, inner support 3 is lining into plastic tube 2 using tool Portion;Finally, the plastic tube 2 of softening is screwed in 1 tapered thread end of steel pipe using tool, it is cooled and shaped.
Embodiment 2: steel pipe 1 cuts into section, processes tapered thread using machining equipment;Inner support 3 cuts into section, removal Surface spikes, end round-corner transition, surface lining plastic anti-corrosion;It is spare that plastic tube 2 cuts into section.Firstly, pre- 2 end of thermal plastic pipe, Make 2 end surface temperature of plastic tube at 100-110 DEG C, until 2 insertion end of plastic tube softens;Secondly, inner support 3 is served as a contrast using tool Enter inside plastic tube 2;Finally, the plastic tube 2 of softening is screwed in 1 tapered thread end of steel pipe using tool, it is cooled and shaped.
