Description
Technical field
The utility model belongs to field of metallurgy, is related to steel-plastics composite pipe, especially a kind of joint sealing of steel-plastics composite pipe
Structure.
Background technology
Steel-plastics composite pipe is to be formed by coating steel pipe after overcoating modeling layer and/or inwall modeling layer, by coating steel pipe
Overcoating modeling layer, can effectively improve the anti-inside and outside corrosion function of coating steel pipe, thus extend the service life of coating steel pipe.But it is existing
Some multiple tubes, the connection of its steel tubing portions is relatively easy to, but the connection sealing of inwall modeling layer is more difficult.Although can use
Adapter of plastic is solved, but due to the effect expanded with heat and contract with cold, the coefficient of expansion between the multiple tube and adapter of plastic of steel is not
Together, it is very easy to cause between joint because of the difference formation gap of the coefficient of expansion, or even comes off.Therefore, existing multiple tube
Connection has had a strong impact on the overall corrosion resistance of multiple tube, so as to influence the service life of multiple tube.
By retrieval, following two related patent documents are found：
1st, a kind of steel plastic compount steel pipe (CN200986078Y) with anti-corrosion connectivity port, including steel plastic compount steel pipe master
Body and anti-corrosion connectivity port, the anti-corrosion connectivity port are to be done be fabricated to by rule or engineering preliminary dimension in advance before anti-corrosion by pipeline
The connection terminal of shape is constituted with its port corrosion-inhibiting coating.Anti-corrosion connectivity port is plough groove type or spigot-and-socket.
2nd, a kind of flanged steel plastic compount steel pipe and flanged pipe, the connection sealing device (CN203115345U) of pipe fitting, its
Including flange plate, pad, lining plastic tube layer, wherein flange plate is welded on the outside of the tube wall of steel plastic compount steel pipe, lining plastic tube layer
Be inlaid in the inner side of steel plastic compount steel pipe, pad is inlaid between two flange plates to be connected, lining plastic tube layer for once into
Type bound edge casts and is coated on pipe end.
By the contrast of technical characteristic, although above-mentioned two patent documents can realize connection between multiple tube and
Sealing, but its complex structure, install inconvenient, have larger difference with the present utility model application.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art to connect quick, good seal performance there is provided a kind of
The sealing structure of steel-plastics composite pipe.
The utility model solves the scheme that its technical problem used：
A kind of sealing structure of steel-plastics composite pipe, the inwall of multiple tube has posted inwall modeling layer, on left multiple tube, the right side
The end of multiple tube is radially formed between a flange, two flanges and fastened using bolt, it is characterised in that：In left multiple tube
Socket is made in one end, and bellmouth is made in one end of right multiple tube, coaxially connected between bellmouth and socket, in left and right multiple tube
A sealing ring is installed between two end face of flange.
Moreover, the inwall modeling layer bending of the left multiple tube envelopes the radial end face of socket, the right multiple tube upwards
Inwall modeling layer bending envelope the radial end face of bellmouth upwards.
Advantage of the present utility model and good effect are：
1st, the connection between this multiple tube uses bell and spigot mode, the connection between two multiple tubes is kept same
Axle, while the docking for also making inwall mould between layer can also be realized coaxially, thereby ensures that being tightly connected between multiple tube, makes
Inwall modeling layer between two multiple tubes keeps effective uniformity, it is to avoid the leakage of connecting portion.
2nd, a sealing ring is installed between the flange of this multiple tube connecting portion, passes through the sealing ring, and inwall modeling layer
Elasticity, the bonding strength between adjustment connecting portion can be made；Meanwhile, the sealing ring can with butt joint carry out secondary seal,
It is prevented effectively from leakage problem.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model；
Fig. 2 for Fig. 1 A-A to cross-sectional view.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by specific embodiment, following examples are to retouch
The property stated, be not limited, it is impossible to limit protection domain of the present utility model with this.
A kind of sealing structure of steel-plastics composite pipe, the inwall of multiple tube 3 has posted inwall modeling layer 4, left multiple tube,
The end of right multiple tube is radially formed between a flange 2, two flanges and fastened using bolt 1.
Innovative point of the present utility model is：
Socket is made in one end of left multiple tube, the inwall modeling layer bending of the left multiple tube envelopes the radial direction of socket upwards
End face；Bellmouth is made in one end of right multiple tube, the inwall modeling layer bending of the right multiple tube envelopes the longitudinal end of bellmouth upwards
Face, referring to Fig. 2 label 6, the label 6 is the dogleg section that inwall moulds layer, so that when left and right multiple tube connects relatively, no
But coaxially connected sealing between left and right multiple tube, and the inwall modeling layer of left and right multiple tube also realizes end face seal, thus protects
The connection and sealing between two multiple tubes are demonstrate,proved.
Because inwall modeling layer is flexible, when being fastened between two flanges using bolt, the inwall of left and right multiple tube can be made
Modeling layer realizes effective elastic terminal surface sealing.In addition, being provided with a sealing ring between two end face of flange of left and right multiple tube
5, to realize the secondary seal at multiunit tube joint position.
