Description
[technical field]
The utility model belongs to technical field of pipeline connection, and in particular to a kind of convex surface high pressure flange connection structure.
[background technique]
High pressure flange connection is exactly that two pipelines, pipe fitting or equipment are first individually fixed at a female flange and a convex surface
On flange, flange gasket is then added between two ring flanges, finally so that it is combined closely two ring flange tensions with bolt
A kind of dismountable connector to get up.It, need to be using male and fomale(M&F) band neck butt welding when pipe design pressure is greater than or equal to 4.0Mpa
Flange, therefore budget inaccuracy will appear concave-convex quantity mismatch and female flange and concave surface occurs sometimes in pipe installation process
Both ends are all that convex flange causes can not be right when the case where flange docks or pipeline docking pipeline or instrument nozzle docking instrument
It connects, excision is needed not match flange, after welding new flange up, weld seam not through carrying out flaw detection, do not protect by the quality of weld seam
Barrier, there are security risks.
The utility model is researched and proposed aiming at the shortcomings in the prior art.
[utility model content]
The technical problem to be solved by the present invention is to provide a kind of convex surface high pressure flange connection structures.
In order to solve the above technical problems, the utility model uses following technical proposals: a kind of convex surface high pressure flange connection
Structure, which is characterized in that include left flange and right flange, the connection that can connect the two is provided between left flange and right flange
Part；The connecting pin of the left flange and right flange is provided with boss；The two sides of the connector are respectively arranged with and boss phase
The groove of cooperation offers the connector aperture being connected with the through-hole on Zuo Falan or right flange in groove.
A kind of convex surface high pressure flange connection structure as described above, which is characterized in that be provided with flange gasket in the groove
Piece, and the depth of groove is greater than the thickness of flange gasket.
A kind of convex surface high pressure flange connection structure as described above, which is characterized in that the boss is annular protrusion, described
Groove be annular groove.
A kind of convex surface high pressure flange connection structure as described above, which is characterized in that the outer diameter of the groove is greater than described
The outer diameter of boss, the diameter of the connector aperture are equal to the diameter of the through-hole.
A kind of convex surface high pressure flange connection structure as described above, which is characterized in that the connector is ring structure.
A kind of convex surface high pressure flange connection structure as described above, which is characterized in that the left flange and right flange pass through
It is bolted.
Compared with prior art, a kind of convex surface high pressure flange connection structure of the utility model achieving the following effects:
The convex surface high pressure flange connection structure of the utility model connects left flange and right flange by connector, solves
Budget inaccuracy will appear concave-convex quantity mismatch and occur what convex flange was docked with convex flange sometimes in pipe installation process
Situation, the assembled length for shortening its pipeline are the short of female flange especially suitable for compact erecting bed, without welding both ends
Adapter tube accomplishes that no-welding-seam processing reduces the risk of leakage of weld seam, improves valve group to accept the connection between two panels convex flange
Packaging efficiency reduces fastener.
[Detailed description of the invention]
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, in which:
Fig. 1 is the perspective view of the utility model；
Fig. 2 is the exploded view of the utility model；
Fig. 3 is the structure chart of the utility model connector.
[specific embodiment]
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
As shown in Figure 1 to Figure 3, a kind of convex surface high pressure flange connection structure includes left flange 1 and right flange 2, Zuo Falan
The connector 3 that can connect the two is provided between 1 and right flange 2；The connecting pin of the left flange 1 and right flange 2 is provided with
Boss 201；The two sides of the connector 3 are respectively arranged with the groove 301 matched with boss 201, offered in groove 301 with
The connector aperture 302 that through-hole 202 on left flange 1 or right flange 2 is connected.The utility model connects left flange by connector
With right flange, solve in pipe installation process budget inaccuracy sometimes will appear concave-convex quantity mismatch occur convex flange with
The case where convex flange docks, the assembled length for shortening its pipeline, especially suitable for compact erecting bed, without welding both ends
The connection between two panels convex flange is accepted for the nipple of female flange, accomplishes that no-welding-seam processing reduces the leakage of weld seam
Risk improves valve group packaging efficiency, reduces fastener, saves cost.
As shown in Figure 1 to Figure 3, in the present embodiment, it is provided with flange gasket 4 in the groove 301, and groove 301
Depth is greater than the thickness of flange gasket 4.The depth of groove is 2mm bigger than the thickness of flange gasket, guarantees that flange gasket can be put into
In groove；The depth of groove is less than or equal to the sum of the thickness that flange gasket adds boss.
As shown in Figure 1 to Figure 3, in the present embodiment, the boss 201 is annular protrusion, and the groove 301 is annular
Groove.
As shown in Figure 1 to Figure 3, in the present embodiment, the outer diameter of the groove 301 is greater than the outer diameter of the boss 201, institute
The diameter for stating connector aperture 302 is equal to the diameter of the through-hole 202.The outer diameter of groove is greater than the diameter 2mm of flange boss.
As shown in Figure 1 to Figure 3, in the present embodiment, the connector 3 is ring structure, convenient for assembling.
As shown in Figure 1 to Figure 3, in the present embodiment, the left flange 1 and right flange 2 are bolted.It is applying in this way
The flange that multiple specifications of the same race can occur in working hour is attached, and is not needed to weld, be saved labour turnover.
