Abstract
The utility model relates to a turbo charging technical field, in particular to high temperature resistant seal gasket. The stainless steel gasket is provided with a plurality of graphite rings which are arranged at intervals and penetrate through the stainless steel gasket, the outer sides of the graphite rings are welded on the stainless steel gasket, and a plurality of limiting clips are arranged on the outer edge of the stainless steel gasket. The utility model discloses the advantage of graphite ring and stainless steel gasket has been combined (the graphite ring is high temperature resistant, has good compression resilience, receives compression deformation resilience during the use, plays sealed thermal-insulated effect stainless steel gasket, forming process is simple, can not have ageing phenomenon), has made the improvement to seal structure.
Description
Technical Field
The utility model relates to a turbo charging technical field, in particular to high temperature resistant seal gasket.
Background
In the working process of the turbocharger, the inlet air temperature and pressure of the volute are high, the temperature of a diesel engine is about 700 ℃, the temperature of a gasoline engine reaches about 900 ℃, and the gas pressure is 3-4bar generally. A graphite ring or a stainless steel gasket is usually adopted for sealing between an engine and a volute air inlet, and the single graphite ring or the single stainless steel gasket has respective disadvantages. The graphite ring is high temperature resistant, has good compression resilience, receives compression deformation resilience during the use, plays sealed thermal-insulated effect, but graphite ring coefficient of friction is little, under the exogenic action, produces easily and slides, and after the long time use, graphite produces ageing phenomenon easily, and the graphite surface drops, uses ageing graphite ring, and sealed effect reduces. The stainless steel gasket is simple in forming process and free of aging, one side of the stainless steel gasket is provided with the arc-shaped groove, the other side of the stainless steel gasket is provided with the arc-shaped boss, the gasket boss is flattened and precisely attached to a sealing surface in the sealing process of the supercharger, so that a good sealing effect is achieved, the flattened iron gasket is displaced in the assembling and disassembling process of the supercharger, the gasket cannot be reused, a new gasket needs to be replaced, and the maintenance cost is increased. There is a need for a sealing gasket to solve the above problems.
Disclosure of Invention
The utility model aims at overcoming the defect that prior art exists, providing a high temperature resistant seal gasket.
Realize the utility model discloses the technical scheme of purpose is: the utility model provides a high temperature resistant seal gasket, has a plurality of graphite rings, the stainless steel gasket is passed to graphite ring interval arrangement, the welding of graphite ring outside is on the stainless steel gasket, stainless steel gasket outer fringe is provided with a plurality of spacing checkposts.
Furthermore, the outer edge of the stainless steel gasket is provided with a plurality of positioning mounting holes matched with the mounting holes of the volute.
Furthermore, the number of the graphite rings is three, and the graphite rings are respectively sleeved on the air passages of the volute.
Furthermore, the number of the limiting clamps is six.
Furthermore, the stainless steel gasket is welded in the middle of the graphite ring.
After the technical scheme is adopted, the utility model discloses following positive effect has:
(1) The utility model discloses the advantage of graphite ring and stainless steel gasket (the graphite ring is high temperature resistant, has good compression resilience, receives compression deformation resilience during the use, plays sealed thermal-insulated effect; stainless steel gasket, shaping simple process can not have ageing phenomenon), has improved seal structure.
Drawings
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is given in conjunction with the accompanying drawings, in which
FIG. 1 is a schematic view of the present invention;
FIG. 2 is a schematic view of the structure of the utility model after installation;
fig. 3 is a side view of the present invention;
FIG. 4 is a schematic view of the assembly structure of the present invention;
fig. 5 is an assembly view of a conventional mechanism.
Detailed Description
The following describes embodiments of the present invention in further detail with reference to the drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships that are based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and simplicity of description, rather than to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1 to 4, the utility model has three graphite rings 1, which are respectively sleeved on the air passage of the volute. Graphite ring 1 is arranged at intervals and passes through stainless steel gasket 2, and the outside of graphite ring 1 is welded on stainless steel gasket 2, and stainless steel gasket 2 outer fringe is provided with six spacing checkposts 21. The outer edge of the stainless steel gasket 2 is provided with a plurality of positioning mounting holes 22 matched with the mounting holes of the scroll. The stainless steel gasket 2 is welded in the middle of the graphite ring 1.
The utility model discloses a theory of operation does: the utility model combines the advantages of the graphite ring and the stainless steel gasket (the graphite ring is high temperature resistant, has good compression resilience, is rebounded by compression deformation during use, plays a role in sealing and heat insulation, and the stainless steel gasket has simple forming process and no aging phenomenon), and improves the sealing structure. The stainless steel gasket is welded around the graphite ring, the circular arc-shaped groove and boss structure of the stainless steel gasket in the figure 5 is eliminated, the limiting clamp is added at the edge of the gasket, and the limiting clamp is bent during use, so that the stainless steel gasket of the graphite ring and the sealing surface are prevented from sliding relatively, and the phenomenon that the graphite ring is aged due to sliding is delayed.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
