Abstract
A kind of engine exhaust sealing gasket, comprise shim body, described shim body is provided with bolt hole and gas passes through hole, described shim body is to consist of upper, middle and lower-ranking corrosion resistant plate, its special way is: on described upper and lower two layers of corrosion resistant plate, corresponding described gas is provided with trapezoidal sealed muscle around by hole, and corrosion resistant plate corresponding gas in described middle level inwardly turns down formation flange by bore edges place.Its beneficial effect is: middle level corrosion resistant plate is turnup structure, makes gas pass through hole and forms difference of height around, and at high temperature difference of height still keeps constant, the sealed muscle continuous and effective of the upper and lower two layers of corrosion resistant plate that adequately protect; Trapezoidal sealed muscle forms double-sealing band under tightening state, makes sealability more reliable.
Description
Technical field
The utility model relates to the engine exhaust sealing gasket that engine exhaust system is used.
Background technique
Development along with engine technology and supercharging technology, the pressure of explosion of motor progressively improves, the temperature of exhausting air also improves thereupon, gas temperature is too high, exhaust sealing system is caused to harmful effect, and available engine exhaust sealing mat structure is two layers or threepayer corrosion resistant plate and presses onboard half ripple sealed muscle.When delivery temperature reaches more than 900 ℃, the hardness of corrosion resistant plate can reduce, and sealed muscle resilience can reduce, and sealability declines, and affects the sealing of gas.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of rational in infrastructure, can guarantee the engine exhaust sealing gasket of sealability under the condition of high temperature.
Technical solution of the present utility model is:
A kind of engine exhaust sealing gasket, comprise shim body, described shim body is provided with bolt hole and gas passes through hole, described shim body is to consist of upper, middle and lower-ranking corrosion resistant plate, its special way is: on described upper and lower two layers of corrosion resistant plate, corresponding described gas is provided with trapezoidal sealed muscle around by hole, and corrosion resistant plate corresponding gas in described middle level inwardly turns down formation flange by bore edges place.
The beneficial effects of the utility model are:
Middle level corrosion resistant plate is turnup structure, makes gas pass through hole and forms difference of height around, and at high temperature difference of height still keeps constant, the sealed muscle continuous and effective of the upper and lower two layers of corrosion resistant plate that adequately protect; Trapezoidal sealed muscle forms double-sealing band under tightening state, makes sealability more reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
In figure: 1-shim body, the upper corrosion resistant plate of 101-, corrosion resistant plate in 102-, corrosion resistant plate under 103-, 104-flange, 2-bolt hole, 3-gas is by hole, the trapezoidal sealed muscle of 4-.
Embodiment
As shown in the figure, the engine exhaust sealing gasket that the utility model relates to, comprise shim body 1, described shim body 1 is provided with bolt hole 2 and gas passes through hole 3, described shim body is to consist of upper, middle and lower-ranking corrosion resistant plate 101,102,103, on described upper and lower two layers of corrosion resistant plate 101,103, corresponding described gas is provided with trapezoidal sealed muscle 4 around by hole 3, and corrosion resistant plate 103 corresponding gases in described middle level are inwardly turned down and formed flange 104 by hole 3 edges.
Claims (1)
1. an engine exhaust sealing gasket, comprise shim body, described shim body is provided with bolt hole and gas passes through hole, described shim body is to consist of upper, middle and lower-ranking corrosion resistant plate, it is characterized in that: on described upper and lower two layers of corrosion resistant plate, corresponding described gas is provided with trapezoidal sealed muscle around by hole, corrosion resistant plate corresponding gas in described middle level inwardly turns down formation flange by bore edges place.
