Description
Technical field
The present invention relates to a kind of pipeline coupling flanges.
Background technology
Flange is called flange flange disk or flange.Flange is the part being connected with each other between pipe and pipe, is used for pipe end
Between connection.All it is at present exposed to air after flanged joint, without safeguard measure, by long-term wet by the rain and burnt by the sun,
Its connector will corrosion, not only affect the fastness of its connection, there are security risk, and dismantle it is also highly difficult, to dimension
The personnel of repairing cause great trouble for.
Invention content
For overcome the deficiencies in the prior art, it the purpose of the present invention is to provide a kind of simple in structure, reasonable design, can carry
High security and pipeline coupling flange convenient for disassembly and assembly.
To solve the above problems, the technical solution adopted in the present invention is as follows：
A kind of pipeline coupling flange, including first pipe, second pipe, first flange and second flange, first method
Orchid is set in first pipe, and second flange is set on second pipe, first pipe and second pipe by first flange and
Second flange is connected；It is arranged with the first ring flat-plate positioned at first flange side in the first pipe, is arranged on second pipe
The second ring flat-plate positioned at second flange side；The side of first ring flat-plate is equipped with annular cover plate, annular cover plate and the first ring flat-plate
Vertical connection, the internal diameter of annular cover plate is identical as the diameter of the second ring flat-plate, the length of the annular cover plate be more than first flange and
The sum of thickness of second flange, first ring flat-plate, annular cover plate and the second ring flat-plate, which connect, to be formed one and can house the first method
Blue and second flange seal chamber.
Further, first ring flat-plate is integrally formed with annular cover plate.
Further, the inner wall of the annular cover plate is equipped with internal thread, and the side of the second ring flat-plate is equipped with and internal thread
External screw thread in mating connection.
Further, neonychium is equipped in the seal chamber, neonychium is respectively arranged on the first ring flat-plate and the second ring flat-plate.
Further, it is equipped with seal groove on the bottom surface of first ring flat-plate and the second ring flat-plate, sealing is equipped in seal groove
Circle.
Compared with prior art, the beneficial effects of the present invention are：First, the first ring flat-plate and the second ring flat-plate can be on pipeline
Sliding, so the installation and removal of two flanges are not interfered with thus, secondly, the first ring flat-plate, annular cover plate and the second ring
After plate is connected, first flange and second flange would not exposed to weather, avoid first flange, second flange and its connection
Part is corroded, and can ensure that the fastness of pipeline connection and easy access personnel carry out it dismounting maintenance, structure letter in this way
Single, reasonable design substantially increases the safety of pipeline.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
In attached drawing, 1 is first pipe, and 2 be second pipe, and 3 be first flange, and 4 be second flange, and 5 be the first ring flat-plate, 6
It is annular cover plate for the second ring flat-plate, 7,8 be seal chamber, and 9 be neonychium, and 10 be sealing ring.
Specific implementation mode
Invention is further described in detail with reference to the accompanying drawings and detailed description.
Such as Fig. 1, a kind of pipeline coupling flange, including first pipe 1, second pipe 2, first flange 3 and second flange 4,
The first flange 3 is set in first pipe 1, and second flange 4 is set on second pipe 2, first pipe 1 and second pipe
2 are connected by first flange 3 with second flange 4；The first ring positioned at 3 side of first flange is arranged in the first pipe 1
Plate 5 is arranged with the second ring flat-plate 6 positioned at 4 side of second flange on second pipe 2；The side of first ring flat-plate 5 is equipped with annular
Cover board 7,5 vertical connection of annular cover plate 7 and the first ring flat-plate, the internal diameter of annular cover plate 7 is identical as the diameter of the second ring flat-plate 6, described
The length of annular cover plate 7 is more than the sum of the thickness of first flange 3 and second flange 4, first ring flat-plate 5, annular cover plate 7 and the
The connection of two ring flat-plates 6 forms a seal chamber 8 that can house first flange 3 and second flange 4.
First ring flat-plate 5 is integrally formed with annular cover plate 7, simple and strong in structure.
The inner wall of annular cover plate 7 is equipped with internal thread, and the side of the second ring flat-plate 6 is equipped in mating connection with internal thread
External screw thread is connected firmly in this way, and dismounting is convenient to.
Neonychium 9 is equipped in seal chamber 8, neonychium 9 is respectively arranged on the first ring flat-plate 5 and the second ring flat-plate 6, passes through protection
Pad can protect two flanges, prevent two ring flat-plates from directly colliding with two flanges, cause breakage.
It is equipped with seal groove on the bottom surface of first ring flat-plate 5 and the second ring flat-plate 6, is equipped with sealing ring 10 in seal groove, in this way may be used
To improve the leakproofness that ring flat-plate is connect with pipeline, prevent rainwater from entering in seal chamber along pipeline.
It will be apparent to those skilled in the art that technical solution that can be as described above and design, make various other
Corresponding change and deformation, and all these changes and deformation should all belong to the protection domain of the claims in the present invention
Within.
