Description
Technical field
The utility model relates to a kind of flange more particularly to a kind of flange assemblies that seal request is high.
Background technique
Flange is called flange flange disk, is part interconnected between pipe and pipe, for the company between pipe end
It connects.In existing flange assembly coupling structure, centre only has a piece of plane sealing pad, as long as gasket seal failure will
Leakage accident occurs, especially for the high pipe-line system of seal request, such as vacuum heat-insulated pipe system, existing flange assembly
Coupling structure cannot meet seal request.
Summary of the invention
In view of the above deficiencies, the utility model provides a kind of tightness high multi-sealed flange assembly.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme.
A kind of multi-sealed flange assembly, including ring flange, plane sealing pad and fastener include flange on ring flange
Hole, is equipped with the small conical socket of outer imperial palace at the aperture of the flange hole of sealing surface one end of ring flange, and two ring flanges pass through
Fastener connection, plane sealing pad are located between the sealing surface of two ring flanges connection；Two ring flanges to link together
The cavity that is formed of two conical sockets in be equipped with seal taper sleeve, the conical surface patch of the lateral surface of seal taper sleeve and two conical sockets
It is tight to be tightly connected, aperture sealed taper sets of holes identical with the aperture of the flange hole of ring flange, sealed taper are equipped on seal taper sleeve
Sets of holes are communicated with flange hole, and the both ends of the sealed taper sets of holes of seal taper sleeve are equipped with sky between the groove bottom of conical socket respectively
Gap；Sealed taper is respectively equipped with perpendicular to sealed taper sets of holes on the lateral surface of the seal taper sleeve of the conical surface position of two conical sockets
Lantern ring connected in star is equipped with O-ring seals in seal taper sleeve annular groove.
Further, the frustoconical bevel angle A of conical socket is 24o.
A kind of multi-sealed flange assembly disclosed by the utility model, first the conical surface of the conical socket of ring flange with it is close
It seals and forms taper linear sealing between the lateral surface of tapered sleeve；Secondly the O-ring seals and ring flange in seal taper sleeve annular groove
Conical socket the conical surface between formed squeeze shape sealing；Plane sealing pad shape is finally used between ring flange and ring flange
At flat seal.The design of triple seal makes the better tightness of flanged joint, is more suitable for the demanding pipeline of sealing performance
System.It avoids that leakage accident occurs.The utility model has the advantages that improving the sealing performance and effect of flanged joint.
