Abstract
The utility model relates to a metal graphite composite type exhaust pipe gasket for an engine. The metal graphite composite type exhaust pipe gasket comprises a gasket body, wherein an exhaust hole is formed in the middle of the gasket body, bolts holes are respectively formed at two sides of the exhaust hole, the gasket body comprises an upper-layer metal plate, a lower-layer metal plate is mounted at the bottom end of the upper-layer metal plate, the inner edge and the outer edge of the upper-layer metal plate are connected with the inner edge and the outer edge of the lower-layer metal plate in a flanging manner, an inner cavity is formed between the upper-layer metal plate and the lower-layer metal plate, and expanded graphite composite plates are filled in the inner cavity. The metal graphite composite type exhaust pipe gasket for the engine has the beneficial effects of simple structure, reasonable design, good sealing property, strong reliability and long service life; and meanwhile, as the graphite does not belong to pollutant, according to the metal graphite composite type exhaust pipe gasket for the engine, the problems of environmental pollution and the like are avoided, and the environmental protection is benefitted.
Description
Technical field
The utility model relates to a kind of motor compound exhaust pipe gasket of metallic graphite carbon.
Background technique
As everyone knows, exhaust pipe gasket is the high-temperature exhaust air that canned motor burning produces, and its operating temperature is generally about 700 ℃, and the continuous action that need bear high-temperature exhaust air, and the sealing operating mode is abominable.This is just so that the quality of exhaust pipe gasket directly affects discharging and the performance of motor, and also whether engine noise being met the demands simultaneously also has direct impact.And along with the raising of the power of motor, people also have higher requirement to sealing reliability and the adaptability of outlet pipe.At present, what domestic exhaust pipe gasket generally adopted is the material that asbestos slate and sheet metal are composited, because the composite material stress relaxation rate of asbestos slate and metal is larger, rebound elasticity is less, thus this exhaust pipe gasket that makes when relatively poor with pad engagement flange facial plane degree, sealing effect neither be very desirable, asbestos belong to pollutant simultaneously, carcinogenic composition is arranged, and many countries ban use of, so asbestos slate composite material outlet pipe can not satisfy usage requirement.
The model utility content
The purpose of this utility model provides a kind of motor with the compound exhaust pipe gasket of metallic graphite carbon, and it is simple in structure, and is reasonable in design, and good airproof performance, reliability is strong and long service life, is conducive to simultaneously environmental protection.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of motor compound exhaust pipe gasket of metallic graphite carbon, comprise shim body, the middle part of described shim body has exhaust port, the both sides of exhaust port have bolt hole, described shim body comprises the upper strata sheet metal, the bottom of described upper strata sheet metal is equipped with the lower metal plate, the inside and outside two edges of described upper strata sheet metal are connected with the inside and outside two edges flange of described lower metal plate, be formed with internal cavities between described upper strata sheet metal and the lower metal plate, be filled with the expanded graphite composite sheet in this internal cavities; Evenly be provided with some thorn plates in the described expanded graphite composite sheet.
The beneficial effects of the utility model are: simple in structure, reasonable in design, and good airproof performance, reliability is strong, and long service life, simultaneously because graphite does not belong to pollutant, thereby so that the utility model has avoided occurring the problems such as environmental pollution, is conducive to environmental protection.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the structural representation that the described a kind of motor of the utility model embodiment is used the compound exhaust pipe gasket of metallic graphite carbon;
Fig. 2 is A-A sectional view among Fig. 1;
Among the figure:
1, shim body; 2, exhaust port; 3, bolt hole; 4, upper strata sheet metal; 5, expanded graphite composite sheet; 6, lower metal plate; 7, thorn plate.
Embodiment
Shown in Fig. 1-2, the described a kind of motor compound exhaust pipe gasket of metallic graphite carbon of the utility model embodiment, comprise shim body 1, the middle part of described shim body 1 has exhaust port 2, the both sides of exhaust port 2 have bolt hole 3, described shim body 1 comprises upper strata sheet metal 4, the bottom of upper strata sheet metal 4 is equipped with lower metal plate 6, the inside and outside two edges of upper strata sheet metal 4 are connected with the inside and outside two edges flange of lower metal plate 6, be formed with internal cavities between described upper strata sheet metal 4 and the lower metal plate 6, be filled with expanded graphite composite sheet 5 in this internal cavities; Expanded graphite composite sheet 5 is interior evenly to be provided with some thorn plates 7.
During concrete the use, upper strata sheet metal 4 and lower metal plate 6 adopt the high temperature resistant stainless steel material.
The utility model is because the inside and outside two edges of upper strata sheet metal 4 are that flange is connected with the inside and outside two edges of lower metal plate 6, thereby so that edge's better tightness of exhaust port 2, and because graphite has high temperature resistant and characteristic thermal expansion, so that expanded graphite composite sheet 5 also has good rebound elasticity when having high-temperature stability, thereby avoided having the undesirable problem of sealing effect between expanded graphite composite sheet 5 and layer sheet metal 4 and the lower metal plate 6, simultaneously evenly be provided with some thorn plates 7 because expanded graphite composite sheet 5 is interior, so that the phenomenon that can not occur sliding between the graphite of Palta type occurs, further guaranteed the sealing between expanded graphite composite sheet 5 and layer sheet metal 4 and the lower metal plate 6.The utility model is simple in structure, and is reasonable in design, good airproof performance, and reliability is strong, and long service life, simultaneously because graphite does not belong to pollutant, thereby so that the utility model has avoided occurring the problems such as environmental pollution, is conducive to environmental protection.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technological scheme, all drops within the protection domain of the present utility model.
