Abstract
The utility model discloses a connecting copper pipe, which belongs to the technical field of pipeline connecting pieces. The connecting copper pipe comprises a copper pipe and connecting screw caps, wherein the connecting screw caps are arranged on both ends of the copper pipe and can slide on the copper pipe; both end surfaces of the copper pipe are provided with flange surfaces; the flange surfaces are integrative double-layer structures; the thicknesses of the double-layer structures are three to four times of the wall thickness of the copper pipe (1). By adopting the structure, when the connecting copper pipe is connected with other pipelines or interfaces through the connecting screw caps, the utility model improves sealing property and connecting strength to prolong the service life of a product.
Description
Technical field
The utility model discloses a kind of connection copper pipe, metal conduit link technical field.
Background technique
Connecting copper pipe is the link of a kind of connecting tube, valve, is mainly used on water heater, air-conditioning, the hot-water heating equipment and plays interconnect function.It mainly comprises copper pipe and places the coupling nut that plays the connecting tube effect at copper pipe two ends that coupling nut can slide, and for increasing sealing and the spacing coupling nut that is connected with pipeline, all is designed to individual layer flanged surface structure on the copper pipe both ends of the surface simultaneously on copper pipe.But find that in actual use when adopting this structure to link to each other with pipeline, its sealing is relatively poor, join strength is lower, thereby causes the working life of product shorter.
Summary of the invention
The utility model is at above-mentioned situation, and purpose is to provide a kind of good airproof performance, the connection copper pipe that join strength is high.
For achieving the above object, the technological scheme that the utility model adopted is: connect copper pipe, comprise copper pipe and place the coupling nut at copper pipe two ends, coupling nut can slide on copper pipe, the copper pipe both ends of the surface are provided with flanged surface, flanged surface is the integral type double layer construction, and its thickness is 2-3 times of copper pipe (1) wall thickness.
After the utility model adopts technique scheme, its advantage is: flanged surface adopts the integral type double layer construction, greatly improved sealing and join strength when the connection copper pipe links to each other with other pipeline or interface by coupling nut, thus the working life of having improved product.
Description of drawings
Fig. 1 is the utility model overall structure schematic representation.
Embodiment
As shown in Figure 1, the utility model comprises copper pipe 1 and places the coupling nut 2 at copper pipe 1 two ends, coupling nut 2 can slide on copper pipe 1, copper pipe 1 both ends of the surface are provided with flanged surface 3, flanged surface 3 adopts extension process to form the integral type double layer construction, bent to double-deck face after both flanged surface 3 having been elongated, its thickness is 2-3 times of copper pipe 1 wall thickness.
The Placement of the utility model and other pipeline or interface is with conventional to be connected copper pipe identical.
Claims (2)
1, connect copper pipe, comprise copper pipe (1) and place the coupling nut (2) at copper pipe (1) two ends, coupling nut (2) can be gone up at copper pipe (1) and slide, and copper pipe (1) both ends of the surface are provided with flanged surface (3), it is characterized in that flanged surface (3) is the integral type double layer construction.
2, connection copper pipe according to claim 1, its thickness of flanged surface (3) that it is characterized in that described two-layer stratigraphic structure are 2-3 times of copper pipe (1) wall thickness.
