Sealing gasket refers to the part that is placed between the connected part and the nut. It is used to protect the surface of the connected part from being scratched by the nut and disperse the pressure of the nut on the connected part. There are many types of gaskets, and there are many kinds of materials such as metal, rubber, asbestos, etc. Different types of gaskets have different functions. Now let us know about the function of gaskets and the selection of gaskets for seals with Xinruituo.
The function of the Sealing gasket is to protect the surface of the connected part from being scratched by the nut, and to disperse the pressure of the nut on the connected part. At the same time, the tip of the bevel of the sealing gasket is against the nut and the supporting surface of the connected part, which also has a relaxing effect.
Selection of sealing gaskets:
1. Temperature
In the process of selecting models, temperature resistance is the primary consideration. This will quickly narrow down the options, especially from 95°C to 540°C. When the ambient temperature used reaches the temperature limit of a particular gasket material, a higher grade material should be replaced. The same is true in some low temperature environments.
2. Application
The effective gasket sealing pressure is derived from the bolt load and the gasket contact surface. Without these parameters, it will not be possible to select a suitable material.
3. Medium
There are tens of thousands of media, and the corrosiveness, oxidation, and permeability of various substances vary greatly. In order to prevent the erosion of the gasket by the cleaning fluid, attention should be paid to the characteristics of the medium.
4. Stress.
Each gasket has its ultimate pressure. If your pressure fluctuates frequently, you need to know the details to make your choice. Otherwise the gasket will be easily damaged.
According to the above basic properties to select the applicable sealing gasket, you can distinguish the quality of the sealing gasket. The above is selection and function of sealing gasket compiled and shared by Xinruituo. For more information, welcome to continue to pay attention.
