Abstract
The utility model provides an accessory used for steel-plastic transition of gas pipes. The accessory is characterized in that the accessory comprises a deformed steel bar and an electric melting connecting pipe, the deformed steel bar is integrally connected to one end of the electric melting connecting pipe in an injection-molding mode, a plurality of electric melting electrodes are arranged at the other end of the electric melting connecting pipe, electrode protection jackets are arranged on the electric melting electrodes, and the deformed steel bar is provided with threads and thus can be connected with a steel pipe. The accessory is low in cost and small in size; construction can be carried out more conveniently and faster, all-day construction can be carried out without using fire and electricity, and thus the construction quality is greatly improved, and engineering cost is reduced.
Description
Technical field
The utility model relates to fuel tube field, more specifically, relates to a kind of accessory of moulding conversion for fuel tube steel.
Background technique
In laying for City Buried Pipeline, more and more PE gas pipelines and PE steel of using are moulded crossover sub, and it has obvious advantage at the aspects such as strong variations of anticorrosion, construction and anti-geology and steel pipe and parts, in combustion gas, is generally applied.Existing Placement is first to fill male connection to squeeze in PE tubing by equipment, in order to guarantee its when mounted fastening, with extrusion equipment, squeeze into a seamless steel sleeve again, be fixed on the part of screw thread extruding inlet pipe, with PE pipe joint and electric smelting, lead directly to and weld again, so just complete a steel and mould conversion accessory.This kind of method operating procedure is more, and will use plurality of devices just can complete, and the more difficult control of sealing of equipment extruding, has sometimes security-hidden trouble.
Summary of the invention
In order to solve the problem of mentioning in background technique; the invention provides a kind of accessory of moulding conversion for fuel tube steel; comprise screw thread steel part and electric smelting connecting tube; described screw thread steel part is by integrated injection molding, to be connected in one end of electric smelting connecting tube; other one end at described electric smelting connecting tube; be provided with a plurality of electric smelting electrodes, described electric smelting electrode is provided with electrode protection cover, and described screw thread steel part is provided with screw thread and can be connected with steel pipe.
Described described electric smelting electrode is copper electrode.
Described a plurality of electric smelting electrodes are 2 electric smelting electrodes.
Described electric smelting connecting tube is polyethylene electric-melting connecting tube.
On described electric smelting electrode, be wound with resistance wire.
Screw thread on described screw thread steel part is hexagonal screw thread.
It is provided by the invention that for fuel tube steel, to mould the accessory cost of conversion low, volume is little, construction more convenient and quicker, without using fiery electricity consumption, can whole day construct, thereby making construction quality greatly improve existing Placement is first to fill male connection to squeeze in PE tubing by equipment, in order to guarantee its when mounted fastening, with extrusion equipment, squeeze into a seamless steel sleeve again, be fixed on the part of screw thread extruding inlet pipe, with PE pipe joint and electric smelting, lead directly to and weld again, so just complete a steel and mould conversion accessory, this kind of method operating procedure is more, and use plurality of devices just can complete, and the more difficult control of sealing of equipment extruding, there is sometimes security-hidden trouble, reduced engineering cost.
Accompanying drawing explanation
Fig. 1 is the sectional view of moulding the accessory of conversion for fuel tube steel provided by the invention.
Wherein, 1 is screw thread steel part, and 2 is electric smelting connecting tube, and 3 is electric smelting electrode, and 4 is electrode protection cover.
Embodiment
As shown in Figure 1; the invention provides a kind of accessory of moulding conversion for fuel tube steel; comprise screw thread steel part and electric smelting connecting tube; described screw thread steel part is by integrated injection molding, to be connected in one end of electric smelting connecting tube; other one end at described electric smelting connecting tube; be provided with 2 electric smelting electrodes; described electric smelting electrode is copper electrode; described electric smelting electrode is provided with electrode protection cover; described screw thread steel part is provided with screw thread and can be connected with steel pipe; described electric smelting connecting tube is polyethylene electric-melting connecting tube, on described electric smelting electrode, is wound with resistance wire.
The present invention makes by the following method:
Screw thread steel part is put in injection mould, completed and be connected by injection moulding embedded component with plastic cement part, then carry out the wiring processing of electric smelting, integral molded plastic has guaranteed sealing.
Above-mentioned fuel tube steel is moulded the accessory of conversion, and compared with prior art, integral molded plastic has reduced equipment double thread and the multiple operation of managing the extruding being connected, and has deducted the assembly of seamless steel sleeve and PE pipe joint, has reduced processing cost.Screw thread steel part has the screw thread form of hexagonal, and while facilitating injection moulding location to be installed and to be connected, instrument is fixing.
