Abstract
The utility model relates to a kind of ripple tooth composite combined pad, comprise and be wound around packing ring, inner ring, be wound around the excircle that packing ring is closely arranged on inner ring, upper surface and/or the lower surface of inner ring are provided with circular groove, the circular groove of upper surface and lower surface is concentric, but the diameter of circular groove is unequal, upper surface and/or the lower surface of inner ring are equipped with expanded graphite.The utility model rebound elasticity is good, and can keep outstanding sealability for a long time, safety reliability is good, without revealing, can repeat fastening, easy for installation, is easy to replace.
Description
Technical field
The utility model relates to a kind of place being applicable to need in the industrial environment of the multiple harshnesses such as high temperature, high pressure, corrosivity are strong, operating mode alternation gasket seal.As chemical plant and boats and ships etc.
Background technique
Conventional pads can not meet the seal request of High Temperature High Pressure, easily falls apart and conquassation under spirotallic gasket overload situations, and when Composition spacer pretightening force is not enough, sealability sharply declines.
Model utility content
Technical problem to be solved in the utility model to provide a kind of
The technological scheme realizing above-mentioned purpose is as follows:
Ripple tooth composite combined pad, it is characterized in that: comprise and be wound around packing ring, inner ring, be wound around the excircle that packing ring is closely arranged on inner ring, upper surface and/or the lower surface of inner ring are provided with circular groove, the circular groove of upper surface and lower surface is concentric, but the diameter of circular groove is unequal.
Preferably, the upper surface of inner ring and/or lower surface are equipped with expanded graphite.
Preferably, described inner ring material is metal material.
Preferably, described inner ring material is for having flexible metal material.Pad is made to have the characteristic of resilience.
Preferably, the excircle being wound around packing ring is provided with positioning ring.
Preferably, described positioning ring is ripple tooth composition ring.
Preferably, described ripple tooth composition ring is annular.Ripple tooth composition ring, under specific sealing configuration or equal conditions, has resilience sealing characteristics equally.
Preferably, the cross section of described circular groove is V-type or U-shaped structure.
Preferably, the excircle of described positioning ring is provided with reticulate structure.Increase frictional force, prevent pad from rotating.
The utility model has close structure, does not fall apart, overload-resistant, can not by the advantage of conquassation when pretightening force is large, when pretightening force hour also can have good sealability.Simultaneously the utility model also has the advantage of high temperature resistant, dynamic compensation temperature and pressure change, thus keeps sealability to stablize; Another advantage of the utility model is that rebound elasticity is good, and can keep outstanding sealability for a long time, safety reliability is good, without revealing, can repeat fastening, most importantly easy for installation, is easy to replace.This pad is applicable to the higher place of the seal requests such as chemical industry, oil refining, natural gas transport and fire fighting supply.

Figure number illustrates: be wound around packing ring 1, inner ring 2, circular groove 3, expanded graphite 4, positioning ring 5.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Ripple tooth composite combined pad is by being wound around part and composite portion is formed, and be wound around part for being wound around packing ring, composite portion is that inner ring and expanded graphite form, and the description of lower mask body structure of the present utility model forms.
In figure, ripple tooth composite combined pad comprises winding packing ring 1, inner ring 2, inner ring 2 preferable alloy material, especially adopt rebound characteristics very good, there is flexible metal material, inner ring plays support reinforcing effect, is wound around packing ring and is closely arranged on the excircle of inner ring, the upper surface of inner ring and/or lower surface are provided with circular groove 3, the circular groove of upper surface and lower surface is concentric, but the diameter of circular groove is unequal, and the concentric circle circular groove mutually staggered makes compound gasket have good rebound elasticity.The upper surface of inner ring and/or lower surface are equipped with expanded graphite 4.The excircle being wound around packing ring is provided with positioning ring 5, and positioning ring 5 is ripple tooth composition ring preferably, and positioning ring can be continuous print annular, also can be the protrusion at interval.The preferred V-type in cross section of circular groove or U-shaped structure.
After combination, the winding packing ring of winding part avoids the shortcoming of falling apart with conquassation, and when pretightening force is excessive, the stress of annular inner portion increases, and the wound portion component of stress increases few, avoids conquassation; When pretightening force is less than normal, because winding part can play good seal action, so also the shortcoming of compound gasket poor sealing can be avoided.The particularly important is, winding part can not be transshipped, safety operation can be ensured, under the condition of High Temperature High Pressure, bolt assembling load is comparatively large, and flange bolt link stores part energy, with compensatory pressure and temperature fluctuation, when making operation, the stress of winding part does not change substantially, thus ensure that constant sealing.Can the fluctuation of adaptive temperature and pressure.
These are only the preferred embodiment of the utility model embodiment; not in order to limit the utility model embodiment; within all spirit in the utility model embodiment and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included in the protection domain of the utility model embodiment.
