Abstract
The utility model relates to a gas pipe network, in particular to a positioning block device of a fully corrosion-resistant steel-plastic inlet pipe. The positioning block device of the fully corrosion-resistant steel-plastic inlet pipe comprises a fully corrosion-resistant steel-plastic inlet pipe (4), wherein a positioning block (2) is welded outside the upper part pipe of a steel-end connector (1) of the fully corrosion-resistant steel-plastic inlet pipe (4), the outer wall of the pipe head is provided with external threads, and a heat shrinkable sleeve (3) is sleeved outside the fully corrosion-resistant steel-plastic inlet pipe (4) and the positioning block (2). According to the positioning block device of the fully corrosion-resistant steel-plastic inlet pipe, the steel-end connector is welded with a positioning block, when the steel-end connector is connected with an indoor pipe network, the inlet pipe can be easily fixed, the connection between the inlet pipe and the indoor pipe network is facilitated, and the positioning block device has the advantages of being fast, convenient, reliable and the like.
Description
Technical field
The utility model relates to gas ductwork, the locating block device of the full antiseptic steel-plastic inlet tube that especially a kind of pipe network is used.
Background technique
At present the fuel tube in buried pipe network is introduced to the user in building, utilize in advance two kinds of steel pipe connectings to be connected into, its joint and buried pipeline preservative treatment scene complete, it is a kind of local anti-corrosion measure, therefore it is not high to exist anticorrosive quality, corrosion air-leakage rate is high, and working life is short, can not effectively avoid slide strip terrace to sink or house sinking, cause inlet tube to destroy and cause the deficiencys such as combustion gas seepage simultaneously.At bulletin on December 5th, 2012, notification number CN202580432U, bulletin " a kind of 90 ° of full anticorrosive steel plastic-steel inlet tubes " patented technology, has solved the electrochemistry corrosion that passes surface location; Utilize the large feature of PE pipe specific elongation, can effectively avoid slide strip terrace to sink or house sinking, cause inlet tube to destroy and cause combustion gas seepage.But when steel end connector is connected with indoor pipe network, need be fixedly clamped with pliers motionless, the outer heat-contraction sleeve of easy damaged steel end connector, time-consuming, make troubles to installing engineering and maintenance.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, adopts steel end connector outer wall to be welded with the locating block device of the full antiseptic steel-plastic inlet tube of positioning block.
The technological scheme that the purpose of this utility model adopts, comprise full antiseptic steel-plastic inlet tube, the steel end connector upper tube outside weld of its full antiseptic steel-plastic inlet tube is connected to positioning block, tube head outer wall has outside thread, and full antiseptic steel-plastic inlet tube and positioning block overcoat have heat-contraction sleeve.
Also have, the steel end connector tube head outside thread of full antiseptic steel-plastic inlet tube does not overlap heat-contraction sleeve.
Also have, positioning block is polygonal or circle.
The features such as the utility model adopts steel end connector to be welded with positioning block, and when being connected with indoor pipe network, easily fixedly inlet tube is motionless, is conveniently connected with indoor pipe network, quick, convenient, reliable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, further illustrate the utility model.
Fig. 1 is the utility model sectional structure schematic diagram.
In figure: the full antiseptic steel-plastic inlet tube of 1-steel end connector 2-positioning block 3-heat-contraction sleeve 4-.
Embodiment
As shown in Figure 1, comprise full antiseptic steel-plastic inlet tube 4, the steel end connector 1 upper tube outside weld of its full antiseptic steel-plastic inlet tube 4 is connected to positioning block 2, tube head outer wall has outside thread, and full antiseptic steel-plastic inlet tube 4 and positioning block 2 overcoats have heat-contraction sleeve 3.The steel end connector 1 tube head outside thread of full antiseptic steel-plastic inlet tube 4 does not overlap heat-contraction sleeve 3.Positioning block 2 is polygonal or circle.
Heat-contraction sleeve 3 adopts denaturation PE plastics to make.Full antiseptic steel-plastic inlet tube 4 adopts the applicant, at bulletin on December 5th, 2012, and notification number CN202580432U, bulletin " a kind of full anticorrosive steel plastic-steel inlet tube " patented technology.
