Description

A kind of flanged pipe coupling arrangement
Technical field
The utility model relates to a kind of flanged pipe coupling arrangement.
Background technique
In pipeline was installed, normally two pipelines, pipe fitting or equipment were fixed on the flange plate earlier separately, between two flange plate, add flange gasket, utilize flanged joint or flange birdsmouth joint etc. with pipeline with bolton together, finished the pipeline butt joint.It is the important Placement of pipeline construction that flange connects, flange connects easy to use, can bear bigger pressure, general flanged pipe coupling arrangement is at present: an end and the pipeline upper flange of flange are fixedly connected, the other end passes through fixedly, and rubber seal is connected with pipeline is direct insertion, rubber seal is installed in the fixedly birdsmouth of coupling, itself and the sealing of inserting pipeline, be that resiliently deformable by rubber realizes, frictional resistance is finished the displacement of general straight cutting pipeline axial between external diameter by pipeline and rubber inside diameter, so, bigger at the line size scattered error, the insertion amount is few, under the situations such as paved surface out-of-flatness, the sealability of pipeline is difficult to guarantee, may causes axially sometimes to come off.Simultaneously, between coupling birdsmouth position and rubber seal, because the design of sealing grooved is not sufficiently complete, the axial connection place of pipe fitting axis is difficult to overlap, the phenomenon that has level and smooth displacement between pipe fitting, under the hydrodynamic pressure of PN10~PN16, there is the hidden danger of leaking in the fixedly birdsmouth place of pipe fitting coupling.
The model utility content
Problem to be solved in the utility model provides a kind of flanged pipe coupling arrangement, its objective is that the fixedly birdsmouth pipe that guarantees coupling connects the sealability between position and rubber seal; Guarantee the coincidence of pipe fitting connection place axis, make pipe fitting have the axially locating anti-slip function, eliminate the pipe fitting coupling and fixedly have the hidden danger of leaking in the birdsmouth place.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of flanged pipe coupling arrangement, comprise flange base, rubber seal, pipeline collar, joiner gland and attachment bolt, the lower end of flange base is a flange arrangement, is used for being connected by bolt with corresponding piping flange or valve flange; The through hole top of flange base is provided with the annular seal groove of placing rubber seal, be provided with the pipeline collar of location joiner gland between the upper surface of flange base and the joiner gland, the upper end of flange base joins joiner gland, pipeline collar, flange base and rubber seal together by attachment bolt; Flange base, rubber seal, pipeline collar and the dead in line of joiner gland.The flange base upper end is in contact with one another with the pipeline collar, and joiner gland internal surface cooperates with the axial 20 ° of oblique angles of pipeline collar outer surface.
The pipeline collar is two to split the metal ring that copper or stainless steel internal surface are provided with the triangle annular projection, the divided ring centerline leaves the gap more than or equal to 2mm, be positioned over the upper surface of flange base, being all 20 ° of oblique angles with the joiner gland cooperates, when attachment bolt drive joiner gland moves down, the pipeline collar can produce the radial displacement of 20-30mm, at utmost satisfies the chucking requirement of various criterion scope pipe fitting, and there is the hidden danger of leaking in the fixedly birdsmouth place of eliminating the pipe fitting coupling; Internal surface adopts the triangle annular projection, can strengthen the self-locking card sigma compactness energy of pipeline.
The internal surface of rubber seal is provided with the zigzag fashion annular projection, and profile is identical with the flange base sealed groove, and the two adopts zero-clearance to cooperate.After pipe fitting inserts joiner, by the resiliently deformable generation sealing effect of rubber; Rotation attachment bolt joiner gland is done axial displacement, and pipeline collar radial contraction produces the locking effect to pipeline, prevents that pipeline axial from coming off.
Flange base lower end snail keyhole is the long trough hole, makes things convenient for the location of flange to connect, and has also satisfied requirement aesthetic in appearance simultaneously.The use that reduces material is axially gone up in the circular arc design of contracting in adopting in no coupling position, flange base middle part, to reduce the deadweight of connected body.
A kind of flanged pipe coupling arrangement of the utility model, adopt technique scheme, compared with prior art, characteristics with novel structure, reliable performance, in abnormity, nonstandard pipeline straight cutting connected, this structural member had more installation efficiency height, good seal performance (having zero seepage characteristics under the hydrodynamic pressure of PN16~PN40), the reliable advantage in pipeline chucking location especially.Owing to guarantee the fixedly birdsmouth point of attachment of coupling and the sealability between rubber seal, guarantee the coincidence of pipe fitting connection place axis, make pipe fitting have the axially locating anti-slip function, eliminate the pipe fitting coupling and fixedly have the hidden danger of leaking in the birdsmouth place.
