One end of part connection is provided with toward the vertically extending annular flange in outside；
Casing, described sleeve pipe include offering through-hole with female canister portion and set on cartridge one end and centre
End plate, wherein cartridge is sheathed on that the annulus is outer to be connect with the annulus screw thread, and the end plate is sheathed on described second
Pipe fitting is outer and the annular flange of second pipe fitting is pressed on the end face of the annulus；
Gasket, the gasket are pressed between the end plate and the end face of the annulus.
In some embodiments, the annular flange side, second pipe fitting outer surface on offer annular
Groove, the gasket and the end plate are clamped between the annular flange and the side wall of the annular groove.
In some embodiments, one end in the annulus far from the annular flange, first pipe fitting appearance
Positioning protrusion is provided on face, the end of the annulus offsets with the positioning protrusion.
In some embodiments, it connect on the outer surface of one end and offers with second pipe fitting in first pipe fitting
An at least annular slot, is provided with sealing ring in the annular slot, and the sealing ring is pressed on institute by second pipe fitting
It states in annular slot.
In some embodiments, the annular slot being opened on first outer surface of pipe fittings includes 2 and interval point
Cloth.
The technical scheme provided by this disclosed embodiment can include the following benefits：
1, the connection structure of the water heating pipe fittings of the utility model, structure is relatively simple, the first pipe fitting and the second pipe fitting it
Between it is easy to connect, and connect intensity and reliability it is higher.
It should be understood that above general description and following detailed description is only exemplary and explanatory, not
The disclosure can be limited.
Description of the drawings
Fig. 1 is the structural schematic diagram of the connection structure of water heating pipe fittings in embodiment.
Specific implementation mode
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Embodiment one：As shown in Figure 1, the present embodiment is a kind of connection structure of water heating pipe fittings, including：
First pipe fitting 1 is fixed with annulus 3 in 1 external welding of the first pipe fitting；
Second pipe fitting 2, second pipe fitting 2 are sheathed on outside first pipe fitting 1, in second pipe fitting 2 and described the
One end of one pipe fitting 1 connection is provided with toward the vertically extending annular flange in outside 201；
Casing 4, described sleeve pipe 4 include being opened with female canister portion 401 and set on 401 one end of cartridge and centre
End plate 402 equipped with through-hole, wherein cartridge 401 are sheathed on outside the annulus 3 and are threadedly coupled with the annulus 3, the end
Plate 402 is sheathed on outside second pipe fitting 2 and the annular flange 201 of second pipe fitting 2 is pressed on to the end face of the annulus 3
On；
Gasket 5, the gasket 5 are pressed between the end plate 402 and the end face of the annulus 3.
The connection structure of the water heating pipe fittings of the present embodiment, structure is relatively simple, between the first pipe fitting 1 and the second pipe fitting 2
It is easy to connect, and connect intensity and reliability it is higher.In addition, first can be effectively improved by newly-increased gasket 5
The leakproofness connected between pipe fitting 1 and the second pipe fitting 2, and then the case where avoid leaking.
Further, annular 201 side of flange, second pipe fitting 2 outer surface on offer annular groove
202, the gasket 5 and the end plate 402 are clamped on the side wall of the annular flange 201 and the annular groove 202
Between, it is simple in structure, each parts can effectively be fixed with this, avoid the axial movement of each parts.
Preferably, one end in the annulus 3 far from the annular flange 201, first pipe fitting 1 outer surface on set
It is equipped with positioning protrusion 100, the end of the annulus 3 offsets with the positioning protrusion 100, and the annulus 3 can be effectively fixed with this,
Avoid the axial movement of the annulus 3.
Further, it is connect on the outer surface of one end with second pipe fitting 2 in first pipe fitting 1 and offers at least one
Annular slot 101, is provided with sealing ring 6 in the annular slot 101, and the sealing ring 6 is pressed on by second pipe fitting 2
In the annular slot 101, it is preferable that be opened in annular slot 101 on 1 outer surface of the first pipe fitting include 2 and
Every distribution, the leakproofness that the first pipe fitting 1 is connect with the second pipe fitting 2 can be improved with this, avoid the generation of leakage scenarios.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this practicality
Novel protection domain.
