Description

Novel metal sealing device

Technical Field

The utility model belongs to the petroleum machinery field, in particular to novel metal seal device.

Background

At present, in the actual production process of an oil field, the existing sealing device for the flange and the sleeve generally adopts a BT rubber sealing ring or an FS rubber sealing ring, and rubber can be hardened and aged and has poor sealing performance under the complex working conditions of high temperature, high pressure and high corrosion if being used for a long time, so that the condition of fluid leakage is generated, and safety accidents are caused, so that the metal sealing device suitable for the complex working conditions is provided under the condition.

Disclosure of Invention

The utility model discloses a solve rubber seal and can not be long-time technical problem who uses under the complicated operating mode of high temperature, high pressure, high corruption, provide a novel metal seal device specially.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a novel metal seal device comprising: the device comprises a flange, a sleeve, a supporting seat, a metal sealing ring, a pressure ring, an O-shaped sealing ring and a connecting bolt; the method is characterized in that: the upper end and the lower end of the metal sealing ring are designed into V-shaped grooves, the inner side and the outer side of the metal sealing ring are designed into C-shaped sealing grooves, the pressing ring and the supporting seat are both provided with V-shaped convex ends, the inner side and the outer side of the pressing ring are provided with sealing grooves, the supporting seat, the metal sealing ring and the pressing ring sequentially pass through a sleeve, the lower end of the supporting seat is self-seated on a flange surface, the V-shaped groove at the lower end of the metal sealing ring is contacted with the V-shaped convex end at the upper end of the supporting seat, the V-shaped convex end at the lower end of the pressing ring is contacted with the V-shaped groove at the upper end of the metal sealing ring, and the O-shaped sealing rings are arranged in the sealing grooves at the inner side and the outer side of the pressing ring and are used for secondary sealing of the outer wall of the sleeve and the inner side of the flange; after the components are assembled, connecting bolts which are uniformly distributed on the flange are tightened under the action of external force, so that the V-shaped convex surfaces of the compression ring and the V-shaped convex surfaces of the supporting seat extrude V-shaped grooves at the upper end and the lower end of the metal sealing ring, and C-shaped sealing grooves at the inner side and the outer side of the metal sealing ring are transversely expanded and deformed, so that the inner C-shaped sealing groove ring is tightly contacted with the outer wall of the sleeve, the outer C-shaped sealing groove ring is tightly contacted with the inner wall of the flange, and the metal sealing of the sleeve and the flange is realized.

The utility model has the advantages that: the metal sealing ring is designed into a structure of V-shaped grooves at the upper end and the lower end and C-shaped sealing grooves at the inner side and the outer side, and is easy to deform under the action of external force, so that the sealing performance is greatly improved; the metal sealing device is reasonable in structure, metal sealing of the sleeve and the flange can be achieved as long as the connecting bolts of the flange are uniformly tightened, and therefore during field operation, operation is simple, and working efficiency is improved.
