Abstract
The utility model relates to a multilayer metal gasket for an engine, which comprises a gasket body. The gasket body is formed by an upper metal plate, an intermediate metal plate and a lower metal plate. The intermediate position of the gasket body is equipped with a bleed hole. The upper metal plate, the intermediate metal plate and the lower metal plate are connected with each other through the flanging and the compressing of the upper metal plate at the bleed hole. The edge of the intermediate metal plate at the bleed hole is equipped with sealed corrugations. The two sides of the bleed hole are equipped with bolt holes. The multilayer metal gasket for an engine has the advantages of artful design, reasonable design, high sealing reliability, long service life and environmental protection.
Description
Technical field
The utility model relates to a kind of motor and uses multilayer metal gasket.
Background technique
As everyone knows, pad is to be used for the high-temperature fuel gas that canned motor produces, and its operating temperature is generally about 500 ℃; And need bear the continuous action of high-temperature fuel gas; The sealing operating mode is abominable, the good and bad discharging and the performance that directly influences motor of pad, and whether engine noise is met the demands all has direct influence simultaneously; Along with the raising of engine power, the sealing reliability and the adaptability of pad are had higher requirement.
Domestic pad adopts asbestos slate and sheet metal to be composited more at present; Because asbestos composite board material stress relaxation rate is bigger, rebound elasticity is little, and especially sealing effect is poor on high power engine, working life short; Asbestos belong to pollutant simultaneously; Carcinogenic composition is arranged, and many countries ban use of, so asbestos composite board material pad can not satisfy usage requirement.
The model utility content
The purpose of the utility model provides a kind of motor and uses multilayer metal gasket, and sealing reliability is strong, and long service life is beneficial to environmental protection, to overcome the above-mentioned deficiency of existing product.
The purpose of the utility model realizes through following technological scheme:
A kind of motor is used multilayer metal gasket; Comprise shim body; Said shim body is made up of upper strata sheet metal, intermediate metal plate and lower metal plate, and the neutral position of shim body is provided with exhaust port, and flange compresses connection at the exhaust port place through the upper strata sheet metal between upper strata sheet metal, intermediate metal plate and the lower metal plate; The intermediate metal plate is provided with the sealing ripple in the edge of exhaust port, and the both sides of exhaust port are equipped with bolt hole.
The beneficial effect of the utility model is: be skillfully constructed, reasonable in design, sealing reliability is strong, long service life, and be beneficial to environmental protection.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the described a kind of motor of the utility model embodiment with multilayer metal gasket;
Fig. 2 is the sectional view of a kind of motor shown in Fig. 1 with multilayer metal gasket A-A along the line.
Among the figure:
11, shim body; 1, upper strata sheet metal; 2, intermediate metal plate; 3, lower metal plate; 4, exhaust port; 5, bolt hole; 6, sealing ripple.
Embodiment
Shown in Fig. 1-2; The described motor of the utility model embodiment is used multilayer metal gasket; Comprise shim body 11; Said shim body 11 is made up of upper strata sheet metal 1, intermediate metal plate 2 and lower metal plate 3, and the neutral position of shim body 11 is provided with exhaust port 4, compresses connection through upper strata sheet metal 1 at exhaust port 4 place's flange between upper strata sheet metal 1, intermediate metal plate 2 and the lower metal plate 3; Intermediate metal plate 2 is provided with sealing ripple 6 in the edge of exhaust port 4, the both sides of exhaust port 4 are equipped with bolt hole 5.
Upper strata sheet metal 1, intermediate metal plate 2 and lower metal plate 3 all adopt stainless steel material, and the thickness of upper strata sheet metal 1 is greater than the thickness of intermediate metal plate 2, and the material hardness of intermediate metal plate 2 is higher than the material hardness of upper strata sheet metal 1.There are certain thickness difference in exhaust port 4 positions and shim body 11 positions; Rely on this thickness difference to form the first road sealing strip; Intermediate metal plate 2 is provided with sealing ripple 6 in exhaust port 4 edges; Form the second road sealing strip, promptly around exhaust port 4, formed the two seals band, can reduce the generation of gas leakage situation effectively.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technological scheme, all belongs to the protection domain of the utility model.
