Description

A kind of double sealing structure hoop type flange
Technical field
The utility model relates to a kind of design of Novel double-seal structure hoop type flange joint, and the pipe transmission system that is applicable to the chemical industry such as submarine oil, natural gas high pressure and contains Korrosionsmedium ensures the agility, sealing and the corrosion resistance that connect.
Background technology
Along with the increase day by day of oil demand amount both at home and abroad, impel the dynamics of marine petroleum exploitation constantly to strengthen. Pipeline is widely used in the industries such as machinery, oil, chemical industry, metallurgy as a kind of special equipment of mass transport, plays a part very important to modernization industry production and people's lives. But along with the development of modern industry, the condition of work of pipe-line system often becomes complex and harshness, pipeline is difficult for installing in complex environment, if common flange installation workload is revealed greatly and easily. Flange forge piece is as one of indispensable strength member in petroleum production system, along with the difficulty of the installation of pipe-line system strengthens, finally causes in installation flange to aim at difficulty and strengthens. In the middle of the transmitting procedure of medium, particularly oil, natural gas etc. contain H2S、CO2And the medium of other corrosive gas, owing to installing and sealing generation leakage, serious harm environment and the people's lives and property safety.
Utility model content
Problem to be solved in the utility model is to provide and a kind of easily installs, quality is light, have hermetically-sealed construction and corrosion resistant hoop type flange.
In order to address the above problem, the utility model provides a kind of double sealing structure hoop type flange, comprise a pair of anchor ear, anchor ear both sides connect by bolt, nut, it is characterized in that, the two ends up and down of described anchor ear are provided with hermetically-sealed construction, and sealing structure comprises the flange cover joint of being located at a pair of and anchor ear at the upper and lower two ends of anchor ear and matching, the flange cutting ferrule of being located at pipeline outside; Between flange cover joint one and flange cover joint two, be provided with environmental sealing ring, runner sealing ring, runner sealing ring matches with the runner on anchor ear; The runner inner wall of described anchor ear is provided with etch resistant layer.
Preferably, between described environmental sealing ring and runner sealing ring, be provided with pressure tester.
Preferably, between the nut at described bolt two ends and anchor ear, be provided with one group of shim pack being become by outer spherical pad, interior spherical shim pack.
Preferably, described nut is spherical nut.
The flange arrangement that the utility model provides, for realizing Fast Installation and the dual-seal protection of pipeline, is a kind of material, energy Fast Installation, good airproof performance, corrosion resistant hoop type flange saved.
