Abstract

The utility model provides a spherical flange joint structure which comprises a spherical flange. An open spherical cavity of the spherical flange is meshed with an open spherical cavity of a spherical flange clamp sleeve through a spherical flange core sleeve, and an elastic sealing ring and a metal sealing ring are arranged between the spherical flange and the spherical flange clamp sleeve. When the spherical flange joint structure is used, one side without the open spherical cavity of the spherical flange is connected with a first pipeline in a welded manner, and one side of a rectangular cavity of the spherical flange clamp sleeve is connected with a second pipeline directly or through a standard butt welded flange. When the spherical flange joint structure is individually used, the maximum deflection angle of the pipelines is 10 degrees. When two spherical flange joint structures are simultaneously used, the pipelines can deviate and deflect maximally by 20 degrees. The spherical flange joint structure overcomes the shortcomings of the prior art, the pipelines can deflect and deviate, double seal protection is realized, and pipeline leakage caused by misalignment in flange mounting is prevented.

Description

A kind of spherical flange joint structure
Technical field

Background technique
At present, pipeline, as a kind of special equipment of mass transport, is widely used in the industries such as machinery, oil, chemical industry, metallurgy, to modernization industry production and people's lives, plays a part very important.Yet, along with the development of modern industry, the operating conditions of pipe-line system often become complex and harshness, pipeline is difficult for installing alignment in complex environment.
When if common flange is installed misalignment, easily produce and leak.In the middle of the transmitting procedure of medium, particularly oil, rock gas etc. contain H 2s, CO 2and the medium of other corrosive gass, owing to installing and sealing generation leakage, serious harm environment and the people's lives and property safety.
Model utility content
The technical problems to be solved in the utility model is to provide and a kind ofly can realizes pipeline deflection and skew, and has double seal protection, prevents the spherical flange joint structure of revealing.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of spherical flange joint structure, it is characterized in that: comprise ball flange, agree with by the chamber of kicking off of ball flange core retainer plate and ball flange cutting ferrule in the chamber of kicking off of ball flange; Between ball flange and ball flange cutting ferrule, be provided with elastic sealing ring and metallic packing ring.
Preferably, described ball flange cutting ferrule is provided with ball flanged joint sealing monitoring holes.
Preferably, described ball flange cutting ferrule is loop configuration, the kick off chamber of the inner one end of loop configuration for coordinating with described ball flange, and the inner the other end of loop configuration is rectangular cavity, the chamber of kicking off connects and is connected with rectangular cavity; Loop configuration rectangular cavity one side connection standard welding neckflange.
Preferably, described ball flange cutting ferrule one end is loop configuration, and the described ball flange cutting ferrule the other end is cone structure; The inner chamber of kicking off for coordinating with described ball flange of loop configuration, cone structure inside is rectangular cavity, the chamber of kicking off connects and is connected with rectangular cavity.
Preferably, described elastic sealing ring is H type elastic sealed body.
Preferably, described metallic packing ring appearance is provided with curing molybdenum layer.
When a kind of spherical flange joint structure that the utility model provides is used, non-chamber one side of kicking off of ball flange connects with the first pipeline is soldered, and rectangular cavity one side of ball flange cutting ferrule is direct or be connected with second pipe by standard welding neckflange.When the spherical flange joint structure that the utility model provides is used separately, the maximum deflection angle that can realize pipeline is 10 °; When two spherical flange joint structures are used simultaneously, can realize the deflection of 20 ° of pipeline skew and maximums.Elastic sealing ring, metallic packing ring double seal protection, prevent from revealing.
The device that the utility model provides has overcome the deficiencies in the prior art, can realize deflection and the skew of pipeline, and double seal protection prevents the pipe leakage that when flange is installed, misalignment causes.
