Abstract

The invention discloses a novel flange component comprising a first flange plate, a second flange plate and a gasket. The first flange plate and the second flange plate match with to-be-connected pipes, and each of the first flange plate and the second flange plate is provided with a tapered boss to be inserted into the to-be-connected pipes. The first flange plate is connected with the second flange plate through bolts, a circular fixing block is arranged on the top surface of the first flange plate, and the inner diameter of the fixing block is larger than that of the first flange plate. The gasket is of a circular shape, the outer diameter of the gasket is identical to the inner diameter of the fixing block, the inner diameter of the gasket is identical to the inner diameter of the first flange plate, and the thickness of the gasket is larger than the height of the fixing block. The first flange plate and the second flange plate are respectively connected with the to-be connected pipes through screws, each joint portion of the boss with the first flange plate and the second flange plate is of a small section of a ring, and each outer diameter of the rings is identical to each inner diameter of the to-be-connected pipes. With the novel flange component, pipe flanges can be connected tightly, sealing is good, and service life is prolonged. The novel flange component is simple in structure and convenient to maintenance.

Description

A kind of novel flange assembly
Technical field
The present invention 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 pipe to be connected, then add a flange gasket in the middle of two flange plate, with bolt etc., two flange plate are fixedly connected with.Often in order to increase the working life of flange gasket; after completing all connection operations; also need to be wound around protective film in the flange gasket outside; although can play certain protective action; but under environment in the open; just there is no much effects, in case flange gasket by weathering, pipeline junction has not just had sealing.In addition, due to time welding between flange plate and pipe to be connected, its maintenance, to change flange plate very inconvenient, must first cut open flange plate, if but do not adopt welding, being threaded and adopt, it connects and defective tightness, and its sealing also can not be guaranteed.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of connection closely, good airproof performance, long service life, and novel flange assembly easy to maintenance.
Technical solution of the present invention is achieved in that a kind of novel flange assembly, comprises the first flange plate, the second flange plate and packing ring; Described the first flange plate, the second flange plate all match with pipe to be connected, and are equipped with the cone boss that inserts in pipe to be connected on the first flange plate, the second flange plate; Described the first flange plate and the second flange plate are bolted; The end face of described the first flange plate is provided with the ring fixed block; The internal diameter of described fixed block is greater than the internal diameter of the first flange plate; Described packing ring is 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 described packing ring is greater than the height of fixed block; Described the first flange plate, the second flange plate are connected with pipe to be connected respectively by screw.
Preferably, described boss and the 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, described packing ring exceeds fixed block 8-12mm.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Novel flange assembly of the present invention, the thickness of packing ring are greater than the height of fixed block, and after being bolted to connection flange plate, packing ring will be subjected to compression swelling, is filled in fixed block; Boss and flange plate joint are provided with the external diameter annulus identical with bore to be connected, make connection more closely, better tightness, and can increase working life of flange assembly.In addition, the present invention program's novel flange assembly, simple in structure, cost is lower, and easy to maintenance.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing l is the sectional view of novel flange assembly of the present invention;
Accompanying drawing 2 is the exploded view of novel flange assembly of the present invention;
Wherein: 1, the first flange plate; 2, the 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, the present invention is described.
Be depicted as a kind of novel flange assembly of the present invention as accompanying drawing 1,2, comprise the first flange plate 1, the second flange plate 2 and packing ring 3; Described the first flange plate 1, the second flange plate 2 all match with pipe 10 to be connected, and are equipped with the cone boss 7 that inserts in pipe 10 to be connected on the first flange plate 1, the second flange plate 2; Described the first flange plate 1 is connected by bolt 9 with the second flange plate 2; The end face of described the first flange plate 1 is provided with ring fixed block 4; The internal diameter of described fixed block 4 is greater than the internal diameter of the first flange plate 1; Described packing ring 3 is ring, and the external diameter of packing ring 3 is identical with the internal diameter of fixed block 4, and the internal diameter of packing ring 3 is identical with the first flange plate 1 internal diameter; The distance that described packing ring 3 exceeds fixed block 4 is 8mm; Described the first flange plate 1, the second flange plate 2 are connected with pipe 10 to be connected respectively by screw 8; Described boss and the first flange plate 1, the second flange plate 2 joints are a bit of annulus 6, and the external diameter of annulus 6 is identical with the internal diameter of pipe 10 to be connected.
The distance that above-mentioned packing ring 3 exceeds fixed block 4 also can be 9mm, 10mm, 11mm or 12mm.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Novel flange assembly of the present invention, the thickness of packing ring are greater than the height of fixed block, and after being bolted to connection flange plate, packing ring will be subjected to compression swelling, is filled in fixed block; Boss and flange plate joint are provided with the external diameter annulus identical with bore to be connected, make connection more closely, better tightness, and can increase working life of flange assembly.In addition, the present invention program's novel flange assembly, simple in structure, cost is lower, and easy to maintenance.
