Description
Technical field
The utility model belongs to conveyance conduit Quick Connect Kit technical field, is specifically related to a kind of pipe flange
Jointing.
Background technology
Pipeline is the most frequently used conveying equipment, and the connection of pipeline needs conduit coupling, conduit coupling energy
Enough connected pipe it is docking together and ensures that junction fully seals.
Application No. 201510345265, entitled high pressure resistant antiseep metal sealing locked clip device formula major diameter
The patent application document of pipeline connecting device discloses a kind of pipeline connecting parts, it solves large-diameter pipeline even
Connect the non-refractory of equipment rubber sealing device existence, service life is short, sealing property is unstable, security
Difference, maintenance and repair cost pressure big, that bear is little, installation requirement is harsh and is not suitable for some special gas
Body, the technical problem of occasion of hydraulic seal, but this connector needs to use special tool in installation process
Tool is installed, and there is the technical problem that installation effectiveness is low and cost is high, and yoke configurations is complicated, difficult processing
Degree is big, yield rate is low.
Summary of the invention
The purpose of this utility model is to solve existing conduit coupling to have that installation effectiveness is low, cost is high, clip
The technical problem that structure is complicated, difficulty of processing is big and yield rate is low, it is provided that a kind of pipe flange jointing.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of pipe flange jointing, including ring flange, screw bolt and nut, wherein: it also includes that pipe connects
With two sealing rings, ring flange is located at the outside of the annular boss that pipe joint end is arranged, and pipe connects close with two
Seal ring is attached separately to the interface of pipeline, and makes the outside of sealing ring contact with the inner side of annular boss, spiral shell
Bolt is located in the bolt hole of ring flange and is fixed on by sealing ring during pipe connects by nut, and makes the anti-of sealing ring
Ooze the outer wall close contact of the edge of a knife and pipeline.
Being provided with annular stop boss in the middle of the inner surface that described pipe connects, pipe connects the two ends of inner surface and is provided with interior sealing
The conical surface.
One end of described sealing ring is provided with the external seal conical surface that the interior sealing cone connect with pipe matches, sealing ring
The other end be provided with boss, the inner surface of sealing ring is provided with the antiseepage edge of a knife, and this antiseepage edge of a knife is positioned at sealing ring
Inner surface is near the side of the external seal conical surface.
Owing to the utility model have employed technique scheme, solve existing conduit coupling and there is installation effect
The technical problem that rate is low, cost is high, yoke configurations is complicated, difficulty of processing is big and yield rate is low.Therefore, with
Background technology is compared, and the utility model has easily installation, low cost, yoke configurations processing simple, easy and becomes
The advantage that product rate is high.
