The same place of O-ring and gasket: both meet the implicit condition: when the sealing contact pressure is greater than the pressure of the sealed medium, the sealing effect is maintained; When the sealing contact pressure is less than the pressure of the sealed medium, the gasket or O-ring is pushed open, and a large amount of leakage occurs in the medium.
The difference between O-ring and gasket: the flat gasket seal contains gaskets, flanges and bolts, forming a complex statically indeterminate system; The sealing contact pressure is provided by the deformation of the bolt. The contact pressure distribution during the operation of the flat gasket is uniform, and when the medium pressure fluctuates, it is greater than the contact pressure, leakage may occur.
In contrast, both of them can be matched when the pressure is unchanged; However, for variable working conditions, when the pressure rises, it is possible to exceed the contact pressure range of the gasket, and the media top opening seal gap will leak. O-ring finishing gasket; In the application, the gasket is only used for static sealing, and the O-ring can be used for both static sealing and dynamic sealing of reciprocating linear motion. In the design, the traditional sealing design method of gasket is not strict enough, and the new design specification of flange gasket is in the process of experimental research; O-ring design as long as the design manual on the line, both simple and reliable, convenient and practical.
In fact, whether it is O-ring or gasket, the most important thing is suitable, can be better play its sealing role. We Haisheng rubber is tailored according to the real needs of customers, we also have a professional team of engineers to tailor for you.
