Abstract

The utility model relates to a fast connecting flange which is matched with valves in the pipelines of the systems of heating, water supply, oil transportation, chemical industry, etc. The fast connecting flange is characterized in that a groove is arranged on the flange connection surface of a valve; a sealing rubber ring is arranged in the groove; one end of a sealing and extruding steel jacket is in a straight mouth, which is inserted in the groove, and the other end is in an oblique mouth; the two end surfaces of a rubber swelling seal ring whose cross section is in a trapezoid are respectively connected with the inner end surfaces of the steel jacket and a pipeline connecting flange in an oblique mouth and are connected into one unit by connecting bolts. The utility model has the advantages of high disassembling and assembling speed, and convenient maintenance; the fast connecting flange can effectively complete the connection of the valve, the flange, and the pipelines when is not influenced by geographical and process conditions.

Description

Fast connecting flange for valve pipeline
The utility model relates to a kind of systematic pipelines and the matching used quick adpting flange of valve such as heating, water supply, oil transportation and chemical industry of being used for.Make between valve, flange and the pipeline and need not weld and be threaded, on the place and material that is specially adapted to not allow to weld.
Pipeline in the past and flange are in connection procedure, usually way is to use screw thread and welds two kinds, the latter is more reliable, this technology has following point in real work: can not rotate with workpiece because of the job site is local narrow in welding process, make the welder can not normal running, often influence welding quality and progress.For addressing this problem, union flange that Chinese patent application CN2071741U proposes without screw thread, it has just solved the connectivity problem between the pipeline and pipeline in the pipeline construction, and can not effectively solve being connected of pipeline and flange and valve.
The purpose of this utility model provides a kind of influence that is not subjected to any geography and technology, during connection without screw thread and welding, in installation process, need only fixing bolt be tightened up operator, just can effectively finish the quick adpting flange of valve pipe of valve and flange, pipeline three interconnect function.
The utility model is achieved in that and has the straight port recess of concentric annular on the flange junction surface of valve, be provided with the rectangular sealing rubber ring in cross section in the groove, sealing extruding steel bushing one end is straight mouthful, is squeezed on the sealing rubber ring in the groove, the other end is angle, and the center is installed with pipeline.The pipeline adpting flange interior edge face that the center is installed with pipeline and sealing extruding steel bushing is angle.The cross section is trapezoidal rubber swelling seal ring and joins with the angle that seals extruding steel bushing and pipeline adpting flange respectively, successively with valve flanges, sealing rubber ring, the sealing extruding steel bushing, rubber swelling seal ring and the pipeline adpting flange that are installed with pipeline are linked to be an integral body by connecting bolt.On the exterior edge face of pipeline adpting flange one end, be provided with a plurality of pipeline positioning bolts.
Earlier rubber seal is put into the groove of valve flanges when installing and using, be inserted in pipeline adpting flange, rubber swelling seal ring and sealing extruding steel bushing successively by pipe end, and the angle of rubber swelling seal ring and pipeline adpting flange and sealing extruding steel bushing is joined, to seal the extruding steel bushing and be straight mouthful of place's aligning valve flanges groove, valve flanges and pipeline adpting flange being connected as a single entity, at last the pipeline positioning bolt is tightened with connecting bolt.
The utility model only adopts steel bushing of two rubber rings and flange owing to need not weld and be threaded, and several connecting bolts and pipeline positioning bolt just can be finished whole operation.So it is quick, easy to maintenance and be not subjected to the influence of geography, process conditions that it has dismounting, just can effectively finish the three's of valve, flange and pipeline interconnect function.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is an overall structure half sectional view of the present utility model.
Open a straight port recess of concentric annular on valve flanges [ 1 ] junction surface, in straight port recess, the rectangular sealing rubber ring in cross section [ 2 ] is housed, sealing extruding steel bushing [ 3 ] is an end of straight mouthful and inserts in the groove, two trapezoidal faces that the cross section is trapezoidal rubber swelling seal ring [ 4 ] respectively with sealing extruding steel bushing [ 3 ] and pipeline adpting flange
[ 5 ] interior edge face is the angle face and joins, and inserts pipeline [ 7 ] then, by connecting bolt [ 6 ] valve flanges [ 1 ] and pipeline adpting flange [ 5 ] is connected as a single entity again.The exterior edge face of pipeline adpting flange one end is provided with a plurality of pipeline positioning bolts [ 8 ].

Claims (1)

1, the quick adpting flange of a kind of valve pipe is connected as one by connecting bolt as cushion rubber, stuffing box gland, pipeline and pipeline adpting flange successively by valve flanges, sealing, it is characterized in that:
A. have the straight port recess of concentric annular on the junction surface of valve flanges [1], be provided with the rectangular sealing rubber ring in cross section [2] in the groove,
B. sealing extruding steel bushing [3] one ends are on the straight mouthful of sealing rubber ring [2] that is squeezed in the groove, and the other end is angle, and the center is installed with pipeline [7],
