Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with attached drawing pair
The utility model is further detailed.
As shown in Fig. 2, the utility model embodiment provides a kind of flange assembly, including tube body 1, the end of the tube body 1
It is provided with butt plate 2, the end far from the tube body 1 is provided with extension 4, the end of the extension 4 on the butt plate 2
It fits on the lateral surface of the butt plate 2.Here medial surface refers on butt plate 2 towards the side of tube body 1, and lateral surface
It is then the side on butt plate 2 away from tube body 1, namely the side that two butt plates 2 are oppositely arranged when composition flange.
As in Figure 2-4, a kind of novel abutted flange provided in an embodiment of the present invention comprising two flange assemblies, phase
It answers, including two tube bodies 1 being connected to each other, the end of the tube body 1 is provided with butt plate 2, the butt plate of two tube bodies 1
It is sealed between 2 docking settings and two butt plates 2 by gasket 3, far from the tube body 1 on each butt plate 2
End is provided with extension 4, and the end of the extension 4 is embedded between two butt plates 2 and abuts the gasket 3.
Specifically, two 1 ends of tube body of flange are connected to each other, two tube bodies 1 are coaxially arranged, and the end of two tube bodies 1 is equal
It is provided with butt plate 2, butt plate 2 is cyclic structure, and when two tube bodies 1 are connected to each other, two butt plates 2 are also connected to each other, and two right
It connects and is provided with gasket 3 between disk 2, the size of gasket 3 is less than or equal to the size of butt plate 2.In the present embodiment, butt plate
2 marginal portion, i.e., the end far from tube body 1 are provided with extension 4, and extension 4 can be cricoid sheet metal structural, be arranged in
The excircle part of butt plate 2, is also possible to the multiple rod-shaped, strips circumferentially arranged on butt plate 2 or sheet extends knot
Structure.By primary or multiple bending, the one end opened is inserted between two butt plates 2 extension 4, and abuts sealing
The outside of pad 3.The advantages of such setting, is, for flange as a whole, it is right to two that the marginal portion opened is extended into
It connects between disk 2, is not exposed to outer structural edge, eliminates potential security risk；Improve gasket 3 and extension 4
Bonding strength；The outside that gasket 3 is abutted by extension 4 reduces its outer probability moved.
The bending of extension 4 at 2 edge of butt plate is entered two by novel abutted flange provided by the embodiment of the utility model
To abut gasket 3 between butt plate 2, first, improving the bonding strength of butt plate 2 Yu gasket 3；Second, eliminating pair
The corner angle for connecing 2 edge of disk, improve safety；Third, limiting by extension 4 to gasket 3, gasket 3 is reduced
The probability of displacement.
In another embodiment provided by the utility model, further, on two butt plates 2 and gasket 3
