Abstract
Heavy caliber inner liner stainless steel pipe, comprises galvanized pipe and Stainless Steel Tube, and Stainless Steel Tube sleeve is in galvanized pipe, and two ends of Stainless Steel Tube form flange, and two flange are pressed on the end face of two ends of galvanized pipe respectively; The inwall of Stainless Steel Tube forms Stainless Steel Tube threading tenon, the outer wall of galvanized pipe forms galvanized pipe threading groove, Stainless Steel Tube threading tenon is linked in galvanized pipe threading groove.Its galvanized pipe and Stainless Steel Tube compound closely, are installed simultaneously and construct also more convenient.
Description
Technical field:
The utility model relates to pipe technology field, more specifically to being lined with stainless running water pipe in one.
Background technique:
In order to avoid water body is secondary polluted in running water pipe, now conventional method is lining with Stainless Steel Tube on the inwall of galvanized pipe, thus avoid tap water to be secondary polluted in body, can also increase the working life of pipeline simultaneously.
As shown in Figure 1, existing small-bore inner liner stainless steel pipe is made up of galvanized pipe A1 and Stainless Steel Tube A2, and two ends of Stainless Steel Tube A2 form flange A21, and flange A21 is pressed on the end face of galvanized pipe A1 bis-end.It, when constructing, is haul swollen head A3 by expander roll A4 to pass from Stainless Steel Tube A2, allows zinc pipe A1 and Stainless Steel Tube A2 closely be combined with each other.Its deficiency is: if the diameter of galvanized pipe A1 is more than after 100mm, adopt again such complex method then easily formed galvanized pipe A1 and Stainless Steel Tube A2 compound not tight, thus make the working life of heavy caliber inner liner stainless steel pipe and quality unsatisfactory, have much room for improvement.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of heavy caliber inner liner stainless steel pipe, and its galvanized pipe and Stainless Steel Tube compound closely, are installed simultaneously and construct also more convenient.
Technology solution of the present utility model is as follows:
Heavy caliber inner liner stainless steel pipe, comprises galvanized pipe and Stainless Steel Tube, and Stainless Steel Tube sleeve is in galvanized pipe, and two ends of Stainless Steel Tube form flange, and two flange are pressed on the end face of two ends of galvanized pipe respectively; The inwall of Stainless Steel Tube forms Stainless Steel Tube threading tenon, the outer wall of galvanized pipe forms galvanized pipe threading groove, Stainless Steel Tube threading tenon is linked in galvanized pipe threading groove.
There is installation annular groove described two ends at galvanized pipe respectively spinning.
The thickness of pipe wall of described Stainless Steel Tube is 3 ~ 6mm.
The beneficial effects of the utility model are:
Its galvanized pipe and Stainless Steel Tube compound closely, are installed simultaneously and construct also more convenient.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
In figure: 1, galvanized pipe; 11, galvanized pipe threading groove; 12, installation annular groove; 2, Stainless Steel Tube; 21, flange; 22, Stainless Steel Tube threading tenon.
Embodiment:
Embodiment: as shown in Figure 2, heavy caliber inner liner stainless steel pipe, comprises galvanized pipe 1 and Stainless Steel Tube 2, and Stainless Steel Tube 2 sleeve is in galvanized pipe 1, and two ends of Stainless Steel Tube 2 form flange 21, and two flange 21 are pressed on the end face of two ends of galvanized pipe 1 respectively; The inwall of Stainless Steel Tube 2 forms Stainless Steel Tube threading tenon 22, the outer wall of galvanized pipe 1 forms galvanized pipe threading groove 11, Stainless Steel Tube threading tenon 22 is linked in galvanized pipe threading groove 11.
There is installation annular groove 12 described two ends at galvanized pipe 1 respectively spinning.
The thickness of pipe wall of described Stainless Steel Tube 2 is 3 ~ 6mm.
Working principle: first by Stainless Steel Tube 2 sleeve in galvanized pipe 1, the helical spring of cone table shape is utilized to pass by from Stainless Steel Tube 2 under power drive, so just, formed out Stainless Steel Tube threading tenon 22 on the inwall of Stainless Steel Tube 2, the outer wall of galvanized pipe 1 has formed out galvanized pipe threading groove 11, and Stainless Steel Tube threading tenon 22 is linked in galvanized pipe threading groove 11.It makes the combination of Stainless Steel Tube 2 and galvanized pipe 1 more tight.
In two ends of galvanized pipe 1, spinning has installation annular groove 12 respectively, facilitates the utility model to utilize other groove pipe fitting to connect like this.Simultaneously spinning installation annular groove 12 out is also conducive to Stainless Steel Tube 2 and galvanized pipe 1 combines more tight, and installation annular groove 12 utilizes commercially available pipe fitting spinning machine to suppress to form.
