Description
Technical field
Flange technical field is the utility model is related to, more particularly to a kind of corrosion protection method flange connection structure.
Background technology
Flange connection is frequently used on the conveyance conduit of oil, chemical industry liquid product, because oil etc. all has corrosivity,
So pipeline will do anti-corrosion treatment, and the anti-corrosion treatment effect of flange connections is poor, and reason is the close of flange connections
Packing sealing structure, it can make have certain gap between two flanges, corrosive liquid is known from experience in gap penetration to sealing gasket,
Cause sealing gasket be corroded damage in addition leak, the useful life of sealing gasket is greatly reduced, improve maintenance use into
This.
Utility model content
The utility model is above-mentioned in order to overcome the shortcomings of, there is provided a kind of corrosion protection method flange connection structure, including two spiral shells
The ring flange 1 connect is tethered, ring flange 1 is provided with centre bore 2 and bolt hole 3, and the ring flange 1 is provided with adapter sleeve 4 and ring-type
Boss 5；
The adapter sleeve 4 includes some spaced connecting plates 41, and the connecting plate 41 is equal in magnitude and is uniformly distributed
In the surrounding of centre bore 2, the medial surface of connecting plate 41 flushes with the inwall of centre bore 2, between adjacent two connecting plates 41 be provided with
The breach 42 that connecting plate 41 is engaged, the breach that the connecting plate 41 on one of ring flange 1 can be inserted on another ring flange 1
In 42；
The boss 5 is located between the lateral surface and bolt hole 3 of connecting plate 41, and boss 5 is provided with the He of groove 51 of annular
The projection 52 of annular, groove 51 are engaged with projection 52, and the projection 52 on one of ring flange 1 may be inserted into another flange
In groove 51 on disk 1.
Further, the corrosion protection method flange connection structure also includes the sealing gasket 6 being arranged between two boss.
Further, the medial surface of the inwall of centre bore 2 and connecting plate 41 is provided with epoxy coating layer 7.
The beneficial effects of the utility model are：In scheme provided by the utility model, the sealing knot on ring flange boss
Structure design is more reasonable, and the projection on two pieces of flanges is embedded in mutually with groove, makes sealing effectiveness more preferable；Company on one piece of ring flange
Fishplate bar is inserted on another piece of ring flange in corresponding breach, and interconnection forms complete tubular, blocks the gap of sealing structure,
Effectively stop corrosive liquid direction of flow sealing gasket, avoid sealing gasket from being corroded, so as to ensure that the useful life of sealing gasket, reduce
Maintenance cost.
