Abstract
The utility model discloses a seal element for a silencer. Seal member for the silencer is characterized by comprising a skeleton formed by a metal wire net in a rolling way. The skeleton is covered with graphite to form a seal element body. The skeleton of the seal member the silencer is formed by the metal wire net in a rolling way; the graphite is pressed on the skeleton, so great damping effect and sealing property is achieved; graphite material possesses low thermal expansion coefficient and high heat conductivity; and with lubrication property of the graphite, lubrication and seal effect can be realized.
Description
Technical field
The utility model relates to seal element field, particularly a kind of silencing apparatus seal element.
Background technique
Vent systems has certain air-flow to discharge, in order to prevent that gas from, in the each connection part leakage of silencing apparatus, producing abnormal sound, therefore need coordinate according to demand certain seal element at the each connection part of silencing apparatus, and the damping effect of current seal element is poor, and can softening transform under hot environment.
Model utility content
Technical problem to be solved in the utility model is for shortcomings and deficiencies of the prior art, provides a kind of good sealing effect, damping effect remarkable and resistant to elevated temperatures silencing apparatus seal element, to address the above problem.
The technical problem that the utility model solves can realize by the following technical solutions:
Silencing apparatus seal element, is characterized in that, comprises and adopts wire gaze to roll the skeleton forming, and is coated with graphite body to form seal element body on described skeleton.
In a preferred embodiment of the present utility model, described seal element body is annular, bowl-type or adpting flange shape.
In a preferred embodiment of the present utility model, be coated with one deck ceramic layer at the outer surface of the seal element body of bowl-type.
In a preferred embodiment of the present utility model, described wire gaze is Stainless Steel Cloth.
In a preferred embodiment of the present utility model, the density of described Stainless Steel Cloth is 4g/cm
3.
Owing to having adopted technological scheme as above, silencing apparatus of the present utility model adopts wire gaze to roll with its skeleton of seal element and forms, and utilizes graphite to be coated skeleton, makes the utlity model has good damping effect and sealing.Graphite material has lower thermal expansion coefficient and higher thermal conductivity in addition, at high temperature, can not soften, and it has lubrication simultaneously, can play lubricated, seal action.Moreover be coated with ceramic coating at the outer surface of the seal element of the utility model bowl-type, and effectively prevent the oxidation of graphite, extend the working life of graphite.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of embodiment's of the utility model structural representation.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Fig. 3 is the another kind of embodiment's of the utility model sectional view.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Embodiment 1
Referring to the silencing apparatus seal element shown in Fig. 1 and Fig. 2, it is the seal element of an annular, this annular seal element comprises that employing wire gaze rolls the cyclic skeleton 200 forming, on cyclic skeleton 200, be suppressed with graphite 300 to form seal ring body 100, wire gaze in the present embodiment is Stainless Steel Cloth, and its density is 4g/cm
3; Certainly also can be other wire gazes.The annular seal element of the present embodiment is compressed on graphite 300 on cyclic skeleton 200, there is good damping effect and sealing, graphite 300 materials have lower thermal expansion coefficient and higher thermal conductivity, and it has lubrication simultaneously, can play lubricated, seal action.
Embodiment 2
Silencing apparatus seal element shown in Figure 3, it is a bowl-shape seal element, this bowl-shape seal element comprises that employing Stainless Steel Cloth rolls the bowl-shape skeleton 200a forming, and is suppressed with graphite 300a to form a bowl-shape seal element body 100a on bowl-shape skeleton 200a.Wire gaze in the present embodiment is Stainless Steel Cloth, and its density is 4g/cm
3; Certainly also can be other wire gazes.
The bowl-shape seal element of the present embodiment is compressed on graphite 300a on bowl-shape skeleton 200a, there is good damping effect and sealing, graphite 300a material has lower thermal expansion coefficient and higher thermal conductivity, at high temperature, can not soften, it has lubrication simultaneously, can play lubricated, seal action.
In order to prevent the oxidation of graphite 300a, extend the working life of graphite 300a, on bowl-shape seal element body 100a outer surface, be coated with one deck ceramic layer 400a.
In addition, the utility model silencing apparatus can also be adpting flange shape with seal element, and the seal element of adpting flange shape is also to have the wire gaze of employing to roll the skeleton forming, and is coated with graphite body to form seal element body on skeleton.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
