Description
Technical field
The utility model relates to a kind of pipeline coupling flanges.
Background technique
Flange is called flange flange disk or flange.Flange is part interconnected between pipe and pipe, is used for pipe end
Between connection.It is all exposed to air after flanged joint at present, without safeguard measure, by long-term wet by the rain and burnt by the sun,
Its connector will corrode, and not only affect the fastness of its connection, and there are security risks, and disassembly is also highly difficult, to dimension
The personnel of repairing cause great trouble for.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of structure is simple, design rationally,
Safety and pipeline coupling flange convenient for disassembly and assembly can be improved.
To solve the above problems, technical solution used by the utility model 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 with the diameter of the second ring flat-plate, the length of the annular cover plate be greater than first flange with
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 accommodate the first method
Blue and second flange seal chamber.
Further, first ring flat-plate and annular cover plate are integrally formed.
Further, the inner wall of the annular cover plate is equipped with internal screw thread, and the side of the second ring flat-plate is equipped with and internal screw 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, is equipped with sealing in seal groove
Circle.
Compared with prior art, the utility model has the beneficial effects that: firstly, the first ring flat-plate and the second ring flat-plate are on pipeline
It can slide, so the installation and removal of two flanges are not interfered with thus, secondly, the first ring flat-plate, annular cover plate and
After two ring flat-plates are connected, first flange and second flange would not exposed to weather, avoid first flange, second flange and its
Connector is corroded, and can guarantee that the fastness of pipeline connection and easy access personnel carry out dismounting maintenance to it in this way, tie
Structure is simple, and design rationally, substantially increases the safety of pipeline.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
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 embodiment
The utility model is described in further 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, annular cover plate 7 is vertical with the first ring flat-plate 5 to be connect, and 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 greater than the sum of first flange 3 and the thickness of second flange 4, first ring flat-plate 5, annular cover plate 7 and the
The connection of two ring flat-plates 6 forms the seal chamber 8 that can accommodate 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 screw thread, and the side of the second ring flat-plate 6 is equipped in mating connection with internal screw thread
External screw thread is connected firmly in this way, and dismounts also very convenient.
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, prevents two ring flat-plates from directly colliding with two flanges, causes 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 can make various other according to the above description of the technical scheme and ideas
Corresponding change and deformation, and all these changes and deformation all should belong to the protection of the utility model claims
Within the scope of.
