Abstract
Welding steel is moulded conversion pipe fitting, comprise that metal steel pipe and PE mould pipe, described PE moulds the sheathed metal locking ring of pipe outer wall, metal locking ring inwall is shaped with seal groove, rubber elastomer is installed in seal groove, rubber elastomer is moulded the sealing of pipe outer wall with PE and is contacted, and described metal locking ring head arranges welding zone A, and metal steel pipe and metal locking ring are welded to connect by welding zone A.The main feature of this programme is that welding zone A is set on metal locking ring, metal steel pipe and metal locking ring are welded to connect by welding zone A, be threaded or buckle the mode such as is connected and compares with existing, be welded to connect as seamless link, it is more firm to connect, better tightness, simple in structure, application is convenient, particularly applicable to the straight tube of various nominal outside diameter different sizes, the production that bent-tube boiler steel is moulded conversion, practical.
Description
Technical field
The utility model relates to a kind of welding steel and moulds conversion pipe fitting, belongs to connection pipe fitting field, is mainly used in buried with combustion gas and feedwater in polyethylene pipe distributing system.
Background technique
At present, in gas pipeline and feedwater piping course of conveying, steel is moulded conversion pipe fitting and is used widely.Country's correlation engineering regulation and stipulation, plastic pipe is access user end directly, therefore, when PE(polyethylene) so after feed channel pressure regulation, register one's residence and grid-connected connection of the steel pipe of having ventilated and PE pipeline all needs steel to mould to change pipe fitting to complete, steel mould conversion pipe fitting be mostly embedded in underground, easily corrosion, so the connection reliability to pipe fitting and sealing requirements are very high.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, provides a kind of and metalwork is set moulding on pipe, and metalwork is connected with steel-pipe welding, and it is firm to connect, anticorrosive, good seal performance, and practical welding steel is moulded conversion pipe fitting.
The technological scheme that the utility model welding steel is moulded conversion pipe fitting is: comprise that metal steel pipe and PE mould pipe, described PE moulds the sheathed metal locking ring of pipe outer wall, metal locking ring inwall is shaped with seal groove, rubber elastomer is installed in seal groove, rubber elastomer is moulded the sealing of pipe outer wall with PE and is contacted, it is characterized in that described metal locking ring head arranges welding zone A, metal steel pipe and metal locking ring are welded to connect by welding zone A.
Welding steel of the present utility model is moulded conversion pipe fitting, main feature is that welding zone A is set on metal locking ring, metal steel pipe and metal locking ring are welded to connect by welding zone A, are threaded or buckle the mode such as is connected and compares with existing, are welded to connect as seamless link, it is more firm to connect, better tightness, simple in structure, application is convenient, particularly applicable to the straight tube of various nominal outside diameter different sizes, the production that bent-tube boiler steel is moulded conversion, practical.
Welding steel of the present utility model is moulded conversion pipe fitting, and described A place, welding zone is shaped with welding inclined-plane, and welding inclined-plane welds mutually with metal steel pipe, inclined-plane convenient welding, firm.Described welding zone A and metallic steel tube-surface apply corrosion-inhibiting coating, prevent corrosion.Described PE moulds in pipe rigidity plug-in part is set, and the radial compression applied that rigidity plug-in part provides realizes the sealing that PE moulds pipe and welds rear metal locking ring and metal steel pipe on metal locking ring inwall.
Brief description of the drawings
Fig. 1 is that welding steel of the present utility model is moulded conversion pipe fitting structural representation.
Embodiment
The utility model relates to a kind of welding steel and moulds conversion pipe fitting, as shown in Figure 1, comprise that metal steel pipe 1 and PE mould pipe 2, described PE moulds the sheathed metal locking ring 3 of pipe 2 outer wall, metal locking ring 3 inwalls are shaped with seal groove 4, and rubber elastomer 5 is installed in seal groove, and rubber elastomer 5 is moulded pipe 2 outer wall sealings with PE and contacted, described metal locking ring 3 heads arrange welding zone A, and metal steel pipe 1 is welded to connect by welding zone A with metal locking ring 3.The main feature of this programme is that welding zone A is set on metal locking ring 3, metal steel pipe 1 is welded to connect by welding zone A with metal locking ring 3, be threaded or buckle the mode such as is connected and compares with existing, be welded to connect as seamless link, it is more firm to connect, better tightness, simple in structure, application is convenient, particularly applicable to the straight tube of various nominal outside diameter different sizes, the production that bent-tube boiler steel is moulded conversion, practical.Described A place, welding zone is shaped with welding inclined-plane 6, and welding inclined-plane 6 welds mutually with metal steel pipe 1, inclined-plane convenient welding, firm.Described welding zone A and metal steel pipe 1 surface apply corrosion-inhibiting coating 7, prevent corrosion.Described PE moulds the pipe 2 interior rigidity plug-in parts 8 that arrange, the sealing that the radial compression applied that rigidity plug-in part provides realizes PE on metal locking ring inwall moulds pipe and the rear metal locking ring of welding and metal steel pipe.
