Abstract
The utility model relates to a flange structure, in particular to a high-pressure pipeline flange connecting structure, which comprises flanges. The flanges are provided with sealing surfaces, and a sealing gasket is arranged at the joint of the flange sealing surfaces on two sides. The high-pressure pipeline flange connecting structure is characterized in that the flange is a welding high-neck flange which is in welding connection with a high-pressure pipeline, and the sealing gasket is a lens gasket made of metal materials. The flange structure has the advantages of simple processing, safe and reliable connection, convenient mounting and maintenance, fine sealing property, simple structure and the like.
Description
Technical field
The utility model relates to a kind of flange arrangement, especially relates to a kind of high pressure pipe line flanged connecting structure.
Background technique
As everyone knows, the prior art flange is connected with the screwed flange connection and is connected two kinds of structures with welding neckflange, the screwed flange linkage structure is simple, seal with metal lens ring face is a sphere, sealing is reliable, and is easy to processing, installs and keeps in repair easily, owing to want machining screw, the end that is threaded exists local strength to weaken and localized stress, and the safety reliability of connection exists not enough; Welding neckflange connects has avoided screwed flange to connect the deficiency that exists, because sealing gasket adopts O type pad or octangonal ring, to the requirement on machining accuracy height, is not easy to install and maintenance.
Summary of the invention
The utility model mainly is at the technical problem of existing in prior technology high pressure pipe line flange attachment security reliability deficiency, installation and maintenance inconvenience etc., and a kind of attachment security good reliability, installation and maintenance high pressure pipe line flanged connecting structure easily is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of high pressure pipe line flanged connecting structure, comprise flange, flange is provided with sealing surface, both sides flange facing joint is provided with sealing gasket, it is characterized in that described flange is the butt welding hubbed flange, described butt welding hubbed flange is by being welded to connect high pressure pipe line, the German-style metal lensring of described sealing gasket for adopting metallic material to make.Flange of the present utility model connects employing metal lens pad sealing welding neckflange linkage structure, avoided prior art owing to wanting machining screw to cause to be threaded end local strength to weaken and stress raisers, sealing gasket is the metal lens pad, sealing is reliable, and is easy to processing, installs and keeps in repair easily.
As preferably, described flange facing is the conical surface, and the sealing surface of described German-style metal lensring is protruding sphere.Reliable and the attachment security of ball face sealing face seal, good reliability.
As preferably, described flange facing is a ledge structure, and the sealing surface of described German-style metal lensring is the two-way conical surface.Good airproof performance and attachment security, good reliability.
As preferably, described ledge structure is a double step structure.Good airproof performance and attachment security, good reliability.
Therefore, the utlity model has that processing is simple, attachment security is reliable, installation and maintenance are convenient, good airproof performance, characteristics such as simple in structure.
