Problems solved by technology

However, due to the fatigue nature of the sealing device material itself, it is easy to cause damage, so that the sealing cannot be achieved
In this way, the sealing device needs to be replaced frequently, which affects the working efficiency of the equipment where the flat or arc surface needs to be sealed.
[0004] Moreover, the existing sealing method using sealing rings or sealing gaskets cannot realize dynamic sealing and cannot meet the occasions that require dynamic sealing

Abstract

The invention relates to a large-diameter sealing element, which comprises two or more than two bulges. The other side, opposite to each bulge, of the sealing element is in a rectangular shape; the length of each bulge is the length of each rectangular shape and is equal to the length to be sealed of a plane or the length to be sealed of an arc surface; a connecting part with a first preset widthis arranged between each two adjacent bulges; a groove is formed in a lower part corresponding to each bulge of the sealing element; or the sealing element is provided with a cushion block under eachconnecting part; and the sealing piece and the cushion blocks as well as one or two sealed planes or arc surfaces or curve surfaces are fixedly installed through a mechanical installation way. The invention provides the sealing element used for ensuring a sealing effect between the planes or the arc surfaces of two parts requiring to be sealed.

Description

technical field [0001] The invention relates to a sealing device, in particular to a large diameter sealing element. Background technique [0002] The sealing between the existing two parts is mostly realized by a sealing ring or a sealing gasket. Since sealing devices such as sealing rings or sealing gaskets are used for sealing, they are generally applied between two coaxial components. And for different shafts, and when the area to be sealed is large, the existing sealing ring or sealing gasket cannot realize sealing well. [0003] Especially when preventing liquid or gas from entering the space between two planes or arc surfaces that need to be sealed, a compressed sealing gasket is usually used to achieve the sealing effect. However, due to the fatigue nature of the sealing device material itself, it is easy to cause damage, so that the sealing cannot be achieved. In this way, the sealing device needs to be replaced frequently, which affects the working efficiency of...
