Description
Technical Field
The utility model relates to a flange seal structure technical field, concretely relates to seal gasket of wound structure.
Background
The sealing principle of the ANSI flange is extremely simple: the two sealing surfaces of the bolt press the flange gasket against each other and form a seal. But this also leads to a break of the seal. In order to maintain the seal, a significant bolt force must be maintained. For which the bolts are made larger. Larger bolts are matched to larger nuts, which means that larger diameter bolts are required to provide for tightening the nuts. It is not known that the larger the diameter of the bolt, the more the applicable flange becomes bent, and the only way is to increase the wall thickness of the flange part. The entire installation will require a great size and weight, which is a particular problem in offshore environments, since weight is always a major concern in such cases. Also, the ANSI flange is fundamentally an ineffective seal requiring 50% of the bolt load to be applied to the compression gasket, with only 50% of the load remaining to maintain compression.
When the flange is sealed daily, a rubber gasket, a non-asbestos gasket and the like are usually adopted to realize the sealing effect of flange connection. But has the defects of poor sealing performance, no pressure resistance, easy abrasion and short service life, and influences the normal operation of equipment. The pressure is seriously even caused to be insufficient, and the equipment cannot normally operate.
