Description
Technical field
The utility model is related to copper pipe technical field, more particularly to a kind of copper pipe.
Background technology
Copper pipe is one kind of nonferrous metal tube, is the seamless pipe of compacting and drawing；Copper pipe possesses firm, corrosion resistant spy
Property, and the first choice installed as modern contractor in the water supply pipe of all Commercial Residential Building's, heat supply, refrigeration piping；At present
Copper pipe can be welded in interface, but be got rusty easily for a long time using the interface of rear copper pipe, and weld can leak
Water, influences service life.
Utility model content
The purpose of this utility model is to provide interface and is difficult to get rusty, and weld is not susceptible to a kind of copper pipe of leak.
The technical solution of the utility model is as follows：
A kind of copper pipe, it is characterised in that including copper pipe, the copper pipe includes cylindrical section and conical section；The conical section is removable
Unload and be connected with transition sleeve, the transition sleeve is externally connected with waterproof jacket；The waterproof jacket include the tapered portion that is connected with transition sleeve and
Cylindrical portion；The transition sleeve outer surface is provided with external screw thread, the tapered portion internal face of waterproof jacket be provided with for transition sleeve be screwed into it is recessed
Internal thread is provided with groove, the groove.
The step surface that the cylindrical portion is connected with tapered portion, which is provided with annular groove, the annular groove, is provided with sealing ring.By setting
Sealing ring, strengthens the sealing effectiveness of interface.
The copper pipe outer surface is provided with netted reinforcing rib layer.Due to setting netted reinforcing rib layer in copper pipe outer surface, increase
The intensity and hardness of strong copper pipe avoid its surface stress from deforming upon, and influence attractive in appearance.
Hardness coating is coated with the copper pipe inner and outer surfaces.Due to setting hardness coating in copper pipe inner and outer surfaces, increase
The hardness of the inside and outside wall of strong copper pipe, it is to avoid its surface stress is deformed upon, and is increased the service life.
The beneficial effects of the utility model are：By setting transition sleeve connecting copper pipe and waterproof jacket；Due to waterproof jacket taper
Portion is threadedly attached on transition sleeve, convenient that waterproof jacket is installed after the completion of copper pipe welding, and dismounting is also compared
Convenient, sealing is higher.
Brief description of the drawings
By detailed description below in conjunction with the accompanying drawings, the utility model is foregoing to incite somebody to action with other objects, features and advantages
Become apparent.
Wherein：Fig. 1 is the utility model structural representation；
In accompanying drawing, 1 is copper pipe, and 2 be cylindrical section, and 3 be conical section, and 4 be transition sleeve, and 5 be waterproof jacket, and 6 be tapered portion, and 7 are
Cylindrical portion, 8 be external screw thread, and 9 be groove, and 11 be annular groove, and 12 be sealing ring, and 13 be netted reinforcing rib layer, and 14 be hardness coating.
Embodiment
It is shown in Figure 1, a kind of copper pipe, it is characterised in that including copper pipe 1, the copper pipe includes cylindrical section 2 and conical section 3；
The conical section is removably connected with transition sleeve 4, and the transition sleeve is externally connected with waterproof jacket 5；The waterproof jacket includes and transition sleeve
The tapered portion 6 and cylindrical portion 7 of connection；The transition sleeve outer surface is provided with external screw thread 8, the tapered portion internal face of waterproof jacket and set
Have and internal thread is provided with the groove 9 being screwed into for transition sleeve, the groove.By setting transition sleeve connecting copper pipe and waterproof jacket；Due to
Waterproof jacket tapered portion is threadedly attached on transition sleeve, convenient that waterproof jacket is installed after the completion of copper pipe welding, and
Dismounting is also more convenient, and sealing is higher.
The step surface that the cylindrical portion is connected with tapered portion, which is provided with annular groove 11, the annular groove, is provided with sealing ring 12.Pass through
Sealing ring is set, strengthens the sealing effectiveness of copper pipe interface.
The copper pipe outer surface is provided with netted reinforcing rib layer 13.Due to setting netted reinforcing rib layer in copper pipe outer surface,
The intensity and hardness for strengthening copper pipe avoid its surface stress from deforming upon, and influence attractive in appearance.
Hardness coating 14 is coated with the copper pipe inner and outer surfaces.Due to setting hardness coating in copper pipe inner and outer surfaces,
Strengthen the hardness of the inside and outside wall of copper pipe, it is to avoid its surface stress is deformed upon, and is increased the service life.
Described be detachably connected can be using threaded connection or clamping.Not only convenient disassembly, and production cost is low.
The hardness coating can use titanium nitride or nitrogen calorize titanium coating.Produced using titanium nitride or nitrogen calorize titanium coating
Cost is low, and hardness is high.
It is described above, only it is preferred embodiment of the present utility model, any formal limit is not done to the utility model
System, it is every according to any simple modification made in technical spirit of the present utility model to above example, equivalent variations, fall
Enter within protection domain of the present utility model.
