Description
Technical field
The utility model belongs to conveyance conduit attachment means technical field, more particularly to pipe flange attachment structure.
Background technology
Flange is applied to the part that pipeline is connected with each other with pipeline as connector, is connected to pipe end, and be widely used in
The multiple fields such as machinery, petrochemical industry and nuclear industry.Existing pipeline is together with the flange welding with convex surface, after pipeline is fixed
Just can not adjustment angle, it is therefore necessary to be first aligned after the flange bolt hole of both sides could fixed -piping, and this structure is to pass through
The convex surface of two flanges extrudes elastic packing packing ring to realize the sealing of interface, and this structure is a resealing, if bullet
Property seal washer it is damaged or aging will seal and unsuccessfully produce leakage.
The content of the invention
The purpose of this utility model is to facilitate alignment method when installing there is provided one kind for above-mentioned problems and shortcomings
Blue bolt hole, with dual sealing functions to improve the dual-seal loose flange attachment structure of sealing property.
What the technical solution of the utility model was realized in：Dual-seal loose flange attachment structure, including movable sleeve
The first adpting flange on the first pipeline, it is fixed on the first pipeline terminal pad of the first pipeline butt end and is fixed on second
Second adpting flange of pipeline butt end, the first adpting flange is located at the rear of the first pipeline terminal pad, the first pipeline terminal pad
The end face junction of docking of second adpting flange is provided with two end-face seal rings, the first adpting flange and the second adpting flange
On be equipped with bolt hole, the first adpting flange is bolted with the second adpting flange.
Further, the docking end face of the first adpting flange is provided with the groove matched with the first pipeline terminal pad.
Further, the first pipeline terminal pad is welded on the first pipeline butt end, and the second adpting flange is welded on the second pipe
The butt end in road.
Further, the first pipeline terminal pad and the first pipeline butt end can also be integrally manufactured, the second adpting flanges
Butt end with second pipe can also be integrally manufactured.
In order that flange connection has dual sealing functions, sealing property, the butt end of the second adpting flange are improved
Face is provided with the ring-type first groove and second groove of concentric different-diameter, and sealing ring includes the first sealing ring and the second sealing ring,
First sealing ring and the second sealing ring are O-ring seals, and the first sealing ring is adapted with first groove, the second sealing ring and
Two grooves are adapted, and the first sealing ring is placed in first groove, and the second sealing ring is placed in second groove.
The utility model by the first pipeline terminal pad by being welded on the first pipeline butt end, and the second adpting flange is welded on
Second pipe butt end, two O-ring seals are individually positioned in the groove of the second adpting flange, the first adpting flange movable sleeve
On the first pipeline, the first adpting flange and the second adpting flange, which are bolted, makes the first pipeline terminal pad connect with second
Acting flange extruding O-ring seals realize the sealing of interface.Adjusted it is achieved thereby that the first adpting flange can be rotated around pipeline
Angle, not only facilitates and is directed at the bolt hole of the first adpting flange and the second adpting flange when mounted, and with dual close
Envelope is acted on, and when the breakage of one of them 0 shape sealing ring or aging, another 0 shape sealing ring may proceed to play sealing function, carry
High sealing performance.
