Detailed explanation of the sealing principle and applicable scene of metal sealing parts

As an important sealing element, metal sealing is widely used in the industrial field. This article will introduce the sealing principles and applicable scenarios of metal seals in detail to help you better understand its working principles and application scope.

1. The principle of sealing:

Metal sealing is tightly exposed to the surface of the sealing surface through metal materials to form an effective seal. The principle of sealing mainly includes the following aspects:

Surface flatness: The sealing effect of metal sealing is closely related to the flatness of the seal surface. When the surface of the seal is high, the metal sealing parts can be closely fitted with the seal surface, forming a good sealing effect.

Elastic deformation: Metal sealing will cause elastic deformation when stressing, so that it will form a good sealing contact with the seal surface to prevent leakage of liquid or gas.

Pre -load capacity: Metal sealing usually needs to apply a certain pre -added capacity to ensure that a stable sealing effect can be maintained under various working conditions.

2. Applicable scenario:

Metal sealing is suitable for many different scenarios and industrial areas, mainly including but not limited to the following aspects:

High temperature and high -pressure environment: Because metal sealing has good high temperature resistance and high pressure resistance, it is suitable for high -temperature and high -pressure environments that require long -term stable work, such as aerospace, petrochemical industry and other fields.

Corrosive medium: Metal sealing can resist the erosion of many corrosive media, so it is suitable for working environments that need to resist corrosion performance, such as chemical industry and ocean.

High -precision requirements: Metal sealing parts have high processing accuracy and size stability, and are suitable for working scenarios that require high precision seal, such as precision instruments and optical equipment.

3. Note:

Sealing surface treatment: When installing metal sealing parts, it should be ensured that the surface of the seal should be high to avoid rough or uneven surfaces.

Pre -load control control: When using metal sealing parts, you need to pay attention to appropriate pre -load capacity to ensure that the sealing part is closely fitted with the seal surface to maintain a stable sealing effect.

Material selection: According to the work environment and media characteristics, choose suitable metal materials and sealing types to ensure the sealing effect and service life.

in conclusion:

Metal sealing through the elastic deformation of metal materials and the tight contact between the surface flatness and the surface of the seal to achieve an effective sealing effect. It is suitable for various working environments such as high temperature, high pressure, corrosive media, and high precision requirements, and has a wide range of application prospects. When using metal sealing parts, pay attention to the sealing surface treatment, pre -load control control and material selection to ensure its sealing effect and service life.
