Problems solved by technology

However, since the gasket is sealed by the sealing line 6, the sealing area is small, resulting in poor sealing effect and prone to high-temperature and high-pressure gas leakage

Embodiment Construction

[0034] In the following, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments, so as to understand the technical ideas claimed in the present invention more clearly.

[0035] Such as Figure 5 , 6 As shown, in order to invent a gasket for the exhaust system of a supercharged engine, it includes a ring-shaped pressing block 2 and an elastic plate 1 embedded in the pressing block 2 along the circumferential direction of the pressing block 2; the The pressing block 2 has a degree of freedom of expansion and deformation along its thickness direction. in, Figure 5 The S direction in is the circumferential direction of the pressing block 2. In actual design, the elastic plate 1 can be embedded in the pressing block 2 along the circumference of the pressing block 2 in a circular, plane spiral or other path. The present invention can improve the stability of the structure of the pressing block 2 by utilizing the su...

Abstract

The invention discloses a sealing gasket for an exhaust system of a supercharged engine and a machining method of the sealing gasket, wherein the sealing gasket for the exhaust system of the supercharged engine comprises an annular pressing block and an elastic plate embedded in the pressing block along the periphery of the pressing block, and the pressing block has the degree of freedom of flexibility and deformation in the thickness direction. Due to the combined design of the pressing block and the elastic plate, the end face of the pressing block is sealed with a flange surface under the action of the elastic plate during pressing, therefore, compared with an existing sealing gasket using a seal line for sealing, the area of a sealed area is increased and the sealing effect is improved; the pressing block is made of mica paper, so that the pressing block has the compressing flexibility; and the machining roughness of the flange surf ace can be made up in the dynamic operation of the engine to exert the effect of micro-sealing, so as to further improve the sealing effect.

Description

[0001] technical field [0002] The invention relates to a gasket used for the exhaust system of a supercharged engine and a processing method thereof. Background technique [0003] The gasket of the supercharged engine exhaust system is installed between the supercharger and the exhaust manifold, which directly affects the performance of the supercharged engine. Due to the large heat load and high boost pressure of the supercharged engine, if the gasket of the exhaust system cannot withstand this severe working condition and reduce the sealing performance, not only will the supercharged engine lose the advantages brought by the supercharging technology, It also reduces engine performance. [0004] Such as figure 1 , 2 As shown, the gasket of the existing supercharged engine exhaust system includes an upper metal corrugated substrate 3, a middle metal corrugated substrate 4, and a lower metal corrugated substrate 5; an upper metal corrugated substrate 3, a middle metal co...
