Abstract
The utility model relates to a novel flange assembly, which comprises a first flange plate, a second flange plate and a gasket, wherein the first flange plate and the second flange plate are both matched with a pipe to be connected and are both provided with a conical boss inserted into the pipe to be connected; the first flange plate and the second flange plate are connected through a bolt; the top surface of the first flange plate is provided with a circular ring-shaped fixed block; the inner diameter of the fixed block is larger than the inner diameter of the first flange plate; the gasket is in a circular ring shape, the outer diameter of the gasket is the same as the inner diameter of the fixed block, and the inner diameter of the gasket is the same as the inner diameter of the first flange plate; the thickness of the gasket is larger than the height of the fixed block; the first flange plate and the second flange plate are respectively connected with the pipe to be connected through screws; and the joints of the boss with the first flange plate and the second flange plate are respectively a small section of circular ring, and the outer diameter of the circular ring is the same as the inner diameter of the pipe to be connected. The novel flange assembly disclosed by the utility model can make the flange connection of pipelines tight, has a good sealing performance, a long service life and a simple structure, and is convenient to maintain.
Description
Technical field
The utility model relates to a kind of flange arrangement, particularly a kind of novel flange assembly that is used for connecting tube.
Background technique
Flange is the important Placement of pipeline construction, comprises two flange plate and a flange gasket.During use, generally at first two flange plate are welded on respectively on the pipe to be connected, in the middle of two flange plate, add a flange gasket then, two flange plate are fixedly connected with bolt etc.Often in order to increase the working life of flange gasket; After accomplishing all connection operations, also need twine protective film, though can play the certain protection effect in the flange gasket outside; But under the environment in the open; Just do not had much effects, in case flange gasket by weathering, pipeline junction has not just had sealing.In addition, owing to time between flange plate and the pipe to be connected welds, its maintenance, replacing flange plate be inconvenience very, must sever flange plate earlier, if but do not adopt welding, being threaded and adopt, it connects and defective tightness, and its sealing also can not get assurance.
The model utility content
The utility model purpose be provide for the deficiency that overcomes existing technology a kind of connection closely, good airproof performance, long service life, and novel flange assembly easy to maintenance.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of novel flange assembly comprises first flange plate, second flange plate and packing ring; Said first flange plate, second flange plate all match with pipe to be connected, and are equipped with the cone boss that inserts in the pipe to be connected on first flange plate, second flange plate; Said first flange plate is connected through bolt with second flange plate; The end face of said first flange plate is provided with the ring fixed block; The internal diameter of said fixed block is greater than the internal diameter of first flange plate; Said packing ring is a ring, and the external diameter of packing ring is identical with the internal diameter of fixed block, and the internal diameter of packing ring is identical with the first flange plate internal diameter; The thickness of said packing ring is greater than the height of fixed block; Said first flange plate, second flange plate are connected with pipe to be connected respectively through screw.
Preferably, the said boss and first flange plate, the second flange plate joint are a bit of annulus, and the external diameter of annulus is identical with the internal diameter of pipe to be connected.
Preferably, said packing ring exceeds fixed block 8-12mm.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The novel flange assembly of the utility model scheme, the thickness of packing ring are greater than the height of fixed block, and behind the bolt mounting flange, packing ring will receive compression swelling, is filled in the fixed block; Boss and flange plate joint are provided with the external diameter annulus identical with bore to be connected, make to connect tight more, better tightness, and can increase the working life of flange assembly.In addition, the novel flange assembly of the utility model scheme, simple in structure, cost is lower, and easy to maintenance.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the sectional view of the novel flange assembly of the utility model;
Accompanying drawing 2 is the exploded view of the novel flange assembly of the utility model;
Wherein: 1, first flange plate; 2, second flange plate; 3, packing ring; 4, fixed block; 5, pipe to be connected; 6, annulus; 7, boss; 8, screw; 9, bolt.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The distance that above-mentioned packing ring 3 exceeds fixed block 4 also can be 9mm, 10mm, 11mm or 12mm.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of novel flange assembly of the utility model scheme, the thickness of packing ring are greater than the height of fixed block, and behind the bolt mounting flange, packing ring will receive compression swelling, is filled in the fixed block; Boss and flange plate joint are provided with the external diameter annulus identical with bore to be connected, make to connect tight more, better tightness, and can increase the working life of flange assembly.In addition, the novel flange assembly of the utility model scheme, simple in structure, cost is lower, and easy to maintenance.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
