Abstract
The utility model discloses a novel little seal gasket, be in including the sealed advance capital for body and setting the rubberised layer on the sealed external surface of advance capital for, set up a plurality of through -holes between sealed advance capital for body upper surface and the lower surface, set up in the through -hole with the I shape wire that the rubberised layer is connected, intensity in order to guarantee rubberised layer coupling part in the through -hole sets up the wire, like copper wire, nonrust steel wire etc. Inhomogeneously lead to the fact local aging failure and the local inhomogeneous phenomenon of being heated in order to avoid outside and inside being heated of seal gasket, and adopt set up the heat conduction silk between the I shape wire, not only make whole heat distribution even, make in addition and insidely be heated evenly with the outside for this device ages at a rate is unanimous, guarantees its leakproofness, simultaneously set up the I shape wire in the through -hole, not only be convenient for set up the heat conduction silk, can guarantee the intensity connected moreover, this device simple structure, realized the good balance of intensity with the leakproofness, be worth using with the popularization.
Description
Technical field
The utility model belongs to tightness system technical field, is specifically related to a kind of novel micro-gasket seal.
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.
The gasket of number of patent application CN96229956.1 good seal performance, applied range, it solve general solid pad high temperature, high pressure or in, low pressure when the leakage problem of the equipment of industrial product that can not solve, sealing pad comprises three layers, the first layer and third layer are high temperature resistant, high pressure seal glue-line, the second layer is middle layer, for metallic gasket, it is high temperature resistant with the first layer and third layer, high pressure seal glue-line is integrally formed. But it does not arrange sealing ply inside gasket, make sealing-ring in use owing to inner seal is not good, cause poorly sealed close or be connected not tight with shim body due to sealing layer, make the phenomenon in use causing gas leakage, and owing to gasket is in seal process, owing to sealing station difference can cause, local heating is uneven causes local ageing too fast, thus causes the phenomenon of gasket partial failure, and it shortens work-ing life and the stability of gasket greatly.
Practical novel content
The purpose of this utility model is to provide that a kind of structure is simple, good sealing effect and possess novel micro-gasket seal of good heat conductivility and stability.
Realizing the technical scheme that the purpose of this utility model adopts is: a kind of novel micro-gasket seal, comprise gasket body and it is arranged on the rubberised layer of described this external surface of gasket, between described gasket body upper surface and lower surface, some through holes are set, the work font wire being connected with described rubberised layer is set in described through hole.
Described gasket body is cellular sealing pad body.
Between described work font wire, heat conductive filament is set.
Described rubberised layer upper surface and lower surface arrange some annular projections or groove.
Described rubberised layer is polytetrafluorethylecoatings coatings.
The utility model, causes sealing failed phenomenon owing to there is gap between gasket fiber for existing gasket seal; And adopting the mode that rubberised layer is set in all sides of gasket body so that this external surface of gasket forms dense seal layer, it is ensured that the effect of sealing; And need to possess certain compressive property due to gasket seal, avoid only being set to cause, after rubberised layer causes life-time service without support, the phenomenon sealing effect reduction and even losing due to rubberised layer distortion.
In addition, in order to the connection degree of compactness ensured between rubberised layer and gasket seal, some through holes are set between gasket seal upper surface and lower surface, make when gluing, the rubberised layer of the rubberised layer of upper surface and lower surface can be connected with each other, simultaneously owing to adopting cellular gasket body to make in the process carrying out gluing, make in the gap that glue liquid infiltrates into cellular sealing pad body, make the point of fixity forming numerous branching shape between rubberised layer and gasket seal, add the attachment force between rubberised layer and gasket body, simultaneously by rubberised layer initial time infiltration, ensure that the stopping property of gasket seal.
In addition, in order to ensure the intensity of rubberised layer connection portion in through hole, wire is set, such as copper wire, Stainless Steel Wire etc., in order to avoid outside and inner being heated of gasket seal uneven to cause the phenomenon that local ageing lost efficacy and local heating is uneven, and adopt and heat conductive filament is set between work font wire, not only make overall uniform heat distribution, and inside and outside are heated evenly so that this device aging speed is consistent, ensures its stopping property; Simultaneously work font wire is set in through hole, is not only convenient to arrange heat conductive filament, and the intensity that connects can be ensured, this apparatus structure is simple, achieve intensity with stopping property well balanced, be worth application and popularization.
