Background technology
For gasket, the sealing connected is by tightening bolt, the compressive stres causing flange and gasket surface in contact and gasket thereof inner bigger, thus make gasket surface and flange surface fit tightly, fill up the microgap of flange surface on the one hand, reduce the porosity of gasket material on the other hand that is reduce by fluid-encapsulated leakage passage. Owing to any manufacture or working method all can not form definitely smooth desirable surface, also can not realize the total blockage of the completely chimeric and hole of sealing member between trim own, thus between the trim contacted with each other and the inside of sealing member always there is small gap or passage. Thus, concerning gasket sealing, leak always inevitable. When medium passes through Bolted Flanged Connection with certain pressure, always occur at seal point place leaking, analyze this kind of phenomenon, it is possible to find that it occurs in two forms, namely so-called " boundary leakage " and " infiltration leakage ".
Boundary leakage: gasket compressive stres is not enough, flange sealing surface is coarse, the thermal distortion of pipeline, mechanical deformation and vibration etc. all can cause the laminating between gasket and flange sealing surface tight and leak. In addition, Bolted Flanged Connection is due to the effect of temperature, pressure under operation operating mode, and bolt anamorphic stretching, gasket creep relaxation, resilience ability decline, and the aging, rotten etc. of gasket material also can cause the leakage between gasket and flange sealing surface. The leakage that this kind occurs between backing and flange sealing surface is called " boundary leakage ".
Infiltration leakage: conventional seals pad is suppressed with rubber bound by vegetable fibre, animal fibre, mineral fibre or man-made fiber usually, or is made by porous materials such as soft graphites. Owing to its tissue loosens, compactness is poor, there is countless minim gap between fiber and fiber, is easy to be soaked into by medium, and particularly under pressure, medium can be infiltrated by the hole of material internal. The leakage phenomenon that this kind occurs in gasket material inside is called " infiltration leakage ".
The material that traditional gasket uses is paronite or without asbestos seal sheet material, these sealing materials all process by main raw of the fiber such as asbestos or non-asbestos mostly. Owing to there is pore between fibrous inside and fiber, causing gasket in use, the medium sealed is gone out from these pore infiltration leakages, makes seal failure. But, the means preventing gasket from revealing at present are coated with seal gum on the front cover of gasket, and boundary leakage can only play certain anti-leak result, and for infiltration leakage, owing to there is no closing or reducing the space of gasket material inside, the generation of infiltration leakage can not be prevented.
Number of patent application CN201520273881.4 discloses a kind of combined labyrinth and carbon gland pad, comprise gasket body, described gasket body comprises again multiple gasket split, described gasket body surface has multiple disconnection place, disconnect from disconnection and form multiple gasket split, body side surface is divided to scribble seal gum at gasket, the sealant layer that sealant layer in disconnection place compares other positions is thick, disconnection place of gasket split has ramp structure, described ramp structure is the face dividing body side surface to form angle with gasket, ramp structure has seal gum, the sealant layer of described disconnection place is layer of silica gel, but this kind of gasket globality is not good, if being applied in automobile vehicle bridge, the phenomenon that wheel box place then very easily causes poor sealing and lost efficacy, and said apparatus in use also exists, local heating is uneven causes local ageing too fast, thus cause the phenomenon of gasket partial failure, shorten work-ing life and the stability of gasket greatly.
