Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, new to this practicality below in conjunction with accompanying drawing
Type embodiment is described in further detail.
This utility model embodiment provides a kind of sealing flange, as it is shown in figure 1, this sealing flange includes the first flange portion
Part 100 and the second flange components 200, the first flange components 100 and the second flange components 200 are provided with bolt hole 01.
First flange components 100 is provided with sealing tenon 110 on the bottom surface of the second flange components 200, seals tenon 110
Between bolt hole 01 and the first semicircle epoxy sleeve 02.
Second flange components 200 is provided with close with seal that tenon 110 fastens on the bottom surface of the first flange components 100
Sealing groove 210, seal groove 210 is between bolt hole 01 and the second semicircle epoxy sleeve 03.Concrete, the first flange components and the
Two flange components are bolted to connection.First flange components and described second flange components are ring flange.
In sum, the sealing flange that this utility model embodiment provides, owing to arranging on the bottom surface of the first flange components
There is sealing tenon, the bottom surface of the second flange components be provided with and seal the seal groove that tenon fastens, compared to prior art, it is not necessary to
Using gasket seal to seal flange face, perfusion epoxies high compressive strength packing material is difficult to from flange face and bolt
Hole leaks, and this improves the sealing of sealing flange.
Further, as in figure 2 it is shown, the bottom surface that sealing tenon 110 and seal groove 210 fasten is provided with n sunk structure
111, n are more than 1.
It is protruding that the bottom surface that seal groove 210 and sealing tenon 110 fasten is provided with n fastened with n sunk structure 111
Structure 112.Example, the bottom surface that sealing tenon and seal groove fasten is provided with 3～10 sunk structures of array arrangement, seals
Groove and seal the bottom surface that fastens of tenon and be provided with array arrangement with sunk structure same number bulge-structure.In Fig. 2 100
Being the first flange components, 200 is the second flange components.It should be noted that Fig. 2 only depicts a sunk structure 111 and
Individual bulge-structure 112, remaining sunk structure and this sunk structure 111 are along being perpendicular to the direction array arrangement of paper, and remaining is protruding
Structure and this bulge-structure 112 are along the direction array arrangement being perpendicular to paper.Seal multiple sunk structures and the seal groove of tenon
The pairing engaging of multiple bulge-structures, improves the sealing effectiveness of snap-latch surface between the first flange components and the second flange components.
Optionally, as it is shown on figure 3, sealing tenon 110 is stepped with the side that seal groove 210 fastens, such as 04 in Fig. 3
Indicated region.The side sealing tenon is stepped with the side of seal groove, makes sealing tenon closely join with seal groove further
To engaging, improve the sealing effectiveness of snap-latch surface between the first flange components and the second flange components.
Optionally, seal tenon to run through and be arranged on the first flange components on the bottom surface of the second flange components；Seal groove passes through
Wear and be arranged on the second flange components on the bottom surface of the first flange components.
Optionally, the snap-latch surface sealing tenon and seal groove is provided with metal binding agent.Example, after metal binding agent solidification
Thickness be 1.5 millimeters.It should be noted that in the defect that two semicircle steel epoxy sleeves are arranged on pipeline to be repaired
Behind position, the snap-latch surface that can in the past seal tenon and seal groove injects metal binding agent, after metal binding agent solidifies, and whole sealing
Flange forms one and seals entirety, strengthens the overall structure of sealing flange, improves the first flange components and the second flange portion
The sealing effectiveness of the snap-latch surface between part.
Fig. 4 shows the second semicircle epoxy set being provided with the second flange components 200 that this utility model embodiment provides
The top view of cylinder 03.In Fig. 4,210 is seal groove, and 06 is the container A filling metal binding agent, and 01 is bolt hole, and bolt hole is used
In through fixing the first flange components and the bolt of the second flange components.Two semicircle steel epoxy sleeves are being arranged on to be repaired
After the rejected region of multiple pipeline, container A can be extruded in the position shown in Fig. 4, and then glues toward injection metal in seal groove
Connect agent.
Seeing Fig. 4, the engaging base sealing the two ends of tenon (being not drawn in Fig. 4) and the two ends of seal groove 210 is polyline shaped,
Region as indicated by Fig. 4 05.The two ends sealing tenon and seal groove are polyline shaped so that seal tenon and the two ends of seal groove
Can tight clamping fit, improve the sealing effectiveness of snap-latch surface between the first flange components and the second flange components.
Additionally, be provided with positioning bolt hole on the first semicircle epoxy sleeve, for through bolt, bolt makes peace
The epoxy sleeve installed keeps certain interval with pipeline outer wall to be repaired.Meanwhile, bolt can fix epoxy sleeve, with
Epoxy sleeve is made not to be moved.
It should be added that also have a kind of sealing flange in prior art, this sealing flange includes two ring flanges
With the epoxy mortar being coated on flange face and bolt, but this sealing flange needs manual site's dispensing to obtain epoxy mortar,
The manual epoxy mortar that coats on flange face and bolt, so, not only time-consuming consumptive material, also cannot ensure construction quality.
For avoiding the epoxies high compressive strength between two semicircle steel epoxy sleeves and pipeline to be repaired to fill material
Material leaks from flange face and bolt hole before curing, and then causes sleeve inner to form cavity, causes reinforcement to lose efficacy, this practicality
New embodiment provides a kind of sealing flange, the first flange components of this sealing flange seal tenon and the second flange components
Seal groove can match engaging, seals multiple sunk structures of tenon and can match with multiple bulge-structures of seal groove and engage, close
The side of envelope tenon is stepped with the side of seal groove, makes sealing tenon closely match with seal groove further and engages, seals tenon
It is polyline shaped with the two ends of seal groove, enables the two ends tight clamping fit of sealing tenon and seal groove, seal tenon and seal groove simultaneously
Snap-latch surface be additionally provided with metal binding agent, improve the sealing of snap-latch surface between the first flange components and the second flange components
Effect.
In sum, the sealing flange that this utility model embodiment provides, owing to arranging on the bottom surface of the first flange components
There is sealing tenon, the bottom surface of the second flange components be provided with and seal the seal groove that tenon fastens, compared to prior art, it is not necessary to
Using gasket seal to seal flange face, perfusion epoxies high compressive strength packing material is difficult to from flange face and bolt
Hole leaks, and this improves the sealing of sealing flange, and the simple in construction of this sealing flange, it is easy to accomplish.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model
Within the scope of protecting.
