Abstract
The utility model provides a flange sealing structure. The flange sealing structure comprises a flange, and a connecting part which is connected with the flange, wherein a sealing ring is arranged between the flange and the connecting part, one end, facing towards the sealing ring, of the flange is provided with a groove, one side, facing towards the flange, of the sealing ring is clamped inside the groove and is matched with the flange, and one side, facing towards the connecting part, of the sealing ring abuts against the connecting part. The flange of the flange sealing structure and the connecting part of the flange sealing structure are simple in dismantling, sealing effect is good, screw fixing is benefited, and the problems that a traditional panel flange is not tight in seal and prone to leaking, over locking of a screw causes the problems that a mouth of the screw is broken and is locked in a dead mode, and when a flange sealing rubber plate is overhauled and dismantled again, the flange sealing rubber plate is prone to being torn and broken.

Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of flange seal structure, flange and link dismounting are simple, good sealing effect, be conducive to screw and fix, solved that the conventional planar flange seal does not sternly easily leak, screw crosses locking and cause that silk mouthful mashed tooth is locked, the problem that the flange seal offset plate easily tears is heavily torn in maintenance open.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: a kind of flange seal structure, comprise flange, the link that is connected with flange, be provided with seal ring between described flange and the link, described flange is provided with groove towards an end of seal ring, described seal ring is stuck in the groove towards a side of flange and cooperates with flange, and described seal ring is against on the link towards a side of link.
As preferably, described seal ring is O-ring seal, and described groove is circular groove, and described seal ring, groove and flange are located on the same central shaft.
As preferably, the slot cross-section of described groove is trapezoidal.
As preferably, described seal ring is two, and two seal rings are located at same and go up and one of them is located in another, and corresponding described flange is provided with two circular grooves that cooperate with two seal rings 2.
As preferably, described flange and link are fixed by screw, and described screw is between two rings.
As preferably, described seal ring is two concentric O type circles.
As preferably, the diameter of described O type circle is than the wide 0.1-1mm of the bottom land of groove, and the diameter of described O type circle equals the slot opening of groove, and the diameter of described O type circle is greater than the groove depth of groove.
As preferably, the diameter of described O type circle is identical with the groove depth of groove.
As preferably, described link is provided with groove towards an end of seal ring, and described seal ring is stuck in the groove towards a side of link and cooperates with link.
As preferably, described link is flange or blind flange.
Beneficial effect:
A kind of flange seal structure that the utility model adopts technique scheme to provide, flange and link dismounting are simple, good sealing effect, be conducive to screw and fix, solved that the conventional planar flange seal does not sternly easily leak, screw crosses locking and cause that silk mouthful mashed tooth is locked, the problem that the flange seal offset plate easily tears is heavily torn in maintenance open.

Embodiment
Embodiment one:
As illustrated in fig. 1 and 2, a kind of flange seal structure, comprise flange 1, the link 5 that is connected with flange 1, be provided with seal ring 2 between described flange 1 and the link 5, described flange 1 is provided with groove 4 towards an end of seal ring 2, described seal ring 2 is stuck in the groove 4 towards a side of flange 1 and cooperates with flange 1, and described seal ring 2 is against on the link 5 towards a side of link 5.Described seal ring 2 is O-ring seal, and described groove 4 is circular groove, and described seal ring 2, groove 4 are located on the same central shaft with flange 1.The slot cross-section of described groove 4 is trapezoidal.Described seal ring 2 is two, and two seal rings 2 are located at same and go up and one of them is located in another, and corresponding described flange 1 is provided with two circular grooves that cooperate with two seal rings 2.Described flange 1 is fixing by screw 3 with link 5, and described screw 3 is between two rings.Described seal ring 2 is two concentric O type circles.The diameter of described O type circle is than the wide 0.1-1mm of the bottom land of groove 4, and the diameter of described O type circle equals the slot opening of groove 4, and the diameter of described O type circle is greater than the groove depth of groove 4.Described link 5 is flange.
Described Sealing 2 materials have nitrile rubber, ethylene-propylene diene copolymer, silicone rubber, neoprene, FFKM, teflon, soluble poly tetrafluoroethylene, contraposition polyphenyl, nylon etc.
In the present embodiment, by 2 sealings of two-layer seal ring, improved sealing effect, solved the offset plate sealing easily aging and again the unloading process Intermediate gasket easily tear the problem such as leak that causes to shreds; Seal ring and flange contact facings are little, and screw is locked slightly and just is easy to sealing, have solved the use offset plate and screw must have been crossed locking, thereby caused the silk mouthful locked problem of mashed tooth; At the flange bottom slot, it is tightr that seal ring and flange are fitted.Seal ring 2 directly adopts O type circle, and the radius of seal ring 2 is more than or equal to the groove depth of groove 4, and is simple in structure, and cost is low.
